There are 6 balloons in small bouquet and 21 balloons in large bouquet.
Step-by-step explanation:
Let,
Number of balloons in small balloon bouquet = x
Number of balloons in large balloon bouquet = y
According to given statement;
2x+3y=75 Eqn 1
2x+y=33 Eqn 2
Subtracting Eqn 2 from Eqn 1
[tex](2x+3y)-(2x+y)=75-33\\2x+3y-2x-y=42\\2y=42[/tex]
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{42}{2}\\y=21[/tex]
Putting y=21 in Eqn 2
[tex]2x+21=33\\2x=33-21\\2x=12[/tex]
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{12}{2}\\x=6[/tex]
There are 6 balloons in small bouquet and 21 balloons in large bouquet.

Final answer:
In solving the system of linear equations, we determined that a small balloon bouquet contains 6 balloons and a large balloon bouquet contains 21 balloons.
Explanation:
Solving a System of Equations
Let's denote the number of balloons in a small bouquet as s and in a large bouquet as l. The given problem provides us with two equations based on the information about the graduation party and Father's Day celebration:
For the graduation party: 2s + 3l = 75
For the Father's Day celebration: 2s + l = 33
Now we solve this system of linear equations to find the values of s and l. Subtracting the second equation from the first gives us:
2s + 3l - (2s + l) = 75 - 33
Which simplifies to:
2l = 42
Dividing by 2 gives us:
l = 21
Now we can plug in the value of l into any of the original equations to find the value of s. Let's use the Father's Day equation:
2s + 21 = 33
Subtracting 21 from both sides gives us:
2s = 12
Finally, dividing by 2 gives us:
s = 6
Therefore, a small balloon bouquet contains 6 balloons and a large balloon bouquet contains 21 balloons.
What is the y-intercept of f(x)=8x^5-3x^3+12
The y intercept is (0, 12)
Solution:
Given function is:
[tex]f(x) = 8x^5 - 3x^3 + 12[/tex]
To find: y intercept
y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system.
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y
Substitute x = 0 in given function
[tex]f(0) = 8(0) -3(0) + 12[/tex]
y = 0 - 0 + 12
y = 12
Thus y - intercept is (0, 12)
Find the indicated probability. Round to three decimal places. The participants in a television quiz show are picked from a large pool of applicants with approximately equal numbers of men and women. Among the last 11 participants there have been only 2 women. If participants are picked randomly, what is the probability of getting 2 or fewer women when 11 people are picked? 0.006 0.033 0.027 0.032
Answer:
0.033
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ (1−p)ⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Here, p = 0.5, q = 0.5, and n = 11.
We need to find P when r is 0, 1, and 2, then add up the results to get the total probability.
r = 0:
P = ₁₁C₀ (0.5)⁰ (0.5)¹¹⁻⁰
P ≈ 0.0005
r = 1:
P = ₁₁C₁ (0.5)¹ (0.5)¹¹⁻¹
P ≈ 0.0054
r = 2:
P = ₁₁C₂ (0.5)² (0.5)¹¹⁻²
P ≈ 0.0269
Therefore, the total probability is:
P = 0.0005 + 0.0054 + 0.0269
P = 0.0328
Round to the thousandths place, the probability is 0.033.

Find the volume of the prism. Round to the nearest tenth if necessary.
Answer:
The volume of the prism will be given by 204.7 cubic cm.
Step-by-step explanation:
The area of a triangle whose three side lengths are given is equal to
Δ = [tex]\sqrt{s(s - a)(s - b)(s - c))}[/tex] .......... (1)
Where, a, b, and c are the three side lengths and s is the half perimeter i.e.
[tex]s = \frac{a + b + c}{2}[/tex] ......... (2)
Now, in our case, [tex]s = \frac{6 + 7 + 6}{2} = 9.5[/tex] {From equation (2)}
So, Δ = [tex]\sqrt{9.5(9.5 - 6)(9.5 - 7)(9.5 - 6)} = 17.05[/tex] sq. cm.

Lin is saving $300 per year in an account that pays 4.5% interest per year, compounded annually. How do I find the value after 20 years?
To find the value after 20 years, use the future value of a series formula with the given parameters, resulting in an approximate amount of $9,321.
Explanation:To find the value of $300 saved annually at 4.5% interest compounded annually after 20 years, we use the future value of a series formula:
FV = [tex]P * ((1 + r)^n - 1) / r[/tex]
Where:
FV = Future value of the seriesP = Yearly deposit ($300)r = Annual interest rate (4.5% or 0.045)n = Number of years (20)Substituting the given values:
FV = $300 * ((1 + 0.045)^20 - 1) / 0.045
= $300 * ((1.045)^20 - 1) / 0.045
= $300 * (2.398 - 1) / 0.045
= $300 * 1.398 / 0.045
= $300 * 31.07
= $9,321
Therefore, after 20 years, the value will be approximately $9,321.

Answer:
The fractions [tex]\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}[/tex] are not in order from least to greatest.
Step-by-step explanation:
Given order of fractions from least to greatest:
[tex]\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}[/tex]
To check if the fractions are in correct order.
Solution:
The fractions given have same numerators but different denominators.
For fractions the higher the denominator the lower is the value of that fraction.
Thus, in the given list the least value fraction will be the fraction with the greatest denominator which is [tex]\frac{3}{12}[/tex] and the greatest value fraction will be the fraction with the least denominator which is [tex]\frac{3}{9}[/tex]
So, the order of the fractions from least to greatest is not correct. Instead the order is from greatest to least.
The correct order from least to greatest should be:
[tex]\frac{3}{12},\frac{3}{11},\frac{3}{10},\frac{3}{9}[/tex].

in trapezium abcd, as shown in the figure, ab is parallel to dc, ad=dc=bc=20cm and ‹a=60°. find: (i) length of ab (ii) distance between ab and dc
Answer:
AB = 40 cm
Distance = [tex]10\sqrt{3}[/tex] cm
Step-by-step explanation:
Draw two heights DE and CF. These heights together with bases of trapezoid form rectangle DEFC. In this rectangle, DC=EF=20 cm.
Consider right triangle ADE. In this triangle, angle ADE has the measure of 30° (the sum of the measures of all interior angles is always 180°, so m∠ADE=180°-60°-90°=30°)
Leg opposite to 30° angle is equal to half of the hypotenuse, so
[tex]AE=\dfrac{1}{2}AD=\dfrac{1}{2}\cdot 20=10\ cm[/tex]
Similarly, in triangle CBF, BF=10 cm.
Hence,
[tex]AB=AE+EF+FB=10+20+10=40\ cm[/tex]
The height of the trapezoid (the second leg of triangle ADE) is the distance between DC and AB. By the Pythagorean theorem,
[tex]AD^2=AE^2+DE^2\\ \\DE^2=20^2-10^2=400-100=300\\ \\DE=\sqrt{300}=10\sqrt{3}\ cm[/tex]
Create an equation where the solutions are 1/3 and 4 plus or minus i sqrt 7
Answer:
[tex] 3 {x}^{3} - 25 {x}^{2} + 35x - 23 = 0[/tex]
Step-by-step explanation:
We want to create an equation that will have the solution
[tex]x = \frac{1}{3},x = 4 + \sqrt{7}i,x = 4 - \sqrt{7}i[/tex]
This implies that:
[tex]3x -1= 0,x -( 4 + \sqrt{7}i) = 0,x - ( 4 - \sqrt{7}i) = 0[/tex]
We put the roots in factored form by reversing the zero product principle to get:
[tex](3x -1)(x -( 4 + \sqrt{7}i))(x - ( 4 - \sqrt{7}i)) = 0[/tex]
We expand the last two parenthesis to get:
[tex](3x - 1)( {x}^{2} - 4x + \sqrt{7}ix - 4x - \sqrt{7}ix + 16 - 7 {i}^{2}) = 0 [/tex]
We simplify to get:
[tex](3x - 1)( {x}^{2} - 8x + 23) = 0[/tex]
We expand further to obtain:
[tex]3 {x}^{3} - 25 {x}^{2} +35x - 23 = 0[/tex]

Mary says 1/8 is
greater than 1/4 because 8 is greater than 4.
Is Mary's reasoning correct? Explain.
Answer:
No, Mary is incorrect. If you turn the fractions into decimals, 1/4 would be 0.25 and 1/8 would be 0.12½. Since 0.25 is greater than 0.12½, Mary is incorrect.
Mary's reasoning is incorrect because in fractions, the larger the denominator, the smaller the fraction's value, making 1/4 greater than 1/8.
Mary's reasoning that 1/8 is greater than 1/4 because 8 is greater than 4 is not correct. In the context of fractions, the larger the denominator (the bottom number), the smaller each part of the whole it represents. Thus, 1/4 is actually greater than 1/8 because dividing something into 4 parts results in larger parts than dividing it into 8 parts. This can be further understood by transforming both fractions into equivalent fractions with a common denominator or by converting them into decimal form (0.25 for 1/4 and 0.125 for 1/8) to directly compare their sizes.
B is the midpoint of AC. If: AB = 9x+1 and BC= 6x+25 Find AC
Answer:
AC = 146
Step-by-step explanation:
Given that B is the midpoint of AC, then
AB = BC, that is
9x + 1 = 6x + 25 ( subtract 6x from both sides )
3x + 1 = 25 ( subtract 1 from both sides )
3x = 24 ( divide both sides by 3 )
x = 8
Hence
AC = AB + BC = 9x + 1 + 6x + 25 = 15x + 26, thus
AC = (15 × 8) + 26 = 120 + 26 = 146
Answer:
146
Step-by-step explanation:
AB = BC (Definition of midpoint) so:
9x+1=6x+25.
Solve it as you would any other algebraic equation >>> 9x+1=6x+25 >>> 9x+1-1=6x+25-1 >>> 9x=6x+24 >>> -6x+9x=6x-6x+24 >>> 3x=24 >>> 3x/3=24/3 >>> x=8
AB=9x+1 >>> AB=9*8+1 >>> AB=73
BC=6x+25 >>> BC=6*8+25 >>> BC=73
AC=AB+BC >>> AC=73+73 >>> AC=146

given: <1 and <2 and supplements, <3 and <4 are supplements, and <1 ≅ <4
prove: <2 ≅ <3
By using the fact of supplement angles of congruent angles are congruent, we proved that ∠2 ≅ ∠3
Step-by-step explanation:
The supplementary angles are:
Two angles their sum is 180°The supplement of an acute angle is an obtuse angle and vice versaThe supplement of a right angle is a right angleIf one angle is supplement to two other angles, then the two angles are equal in measure (if 50° is supplement to angles X and Y, then X and y must be 130°)Supplement angles of congruent angles are congruent (If angles X and Y are supplement to angles A , B and angles A , B are congruent, then angles X and Y are congruent∵ ∠1 and ∠2 are supplementary
∴ m∠1 + m∠2 = 180° ⇒ (1)
∵ ∠3 and ∠4 are supplementary
∴ m∠3 + m∠4 = 180° ⇒ (2)
We can equate the left hand sides of (1) and (2) because the right hand sides are equal
∴ m∠1 + m∠2 = m∠3 + m∠4 ⇒ (3)
∵ ∠1 ≅ ∠4
∴ m∠1 = m∠4
- Substitute m∠4 by m∠1 in (3)
∴ m∠1 + m∠2 = m∠3 + m∠1
- Subtract m∠1 from both sides
∴ m∠2 = m∠3
∴ ∠2 ≅ ∠3
By using the fact of supplement angles of congruent angles are congruent, we proved that ∠2 ≅ ∠3

The mass of two sacks of potatoes is 168 grams. One-eight of the mass of Sack A and three-quarter of the mass of Sack B is 76 grams. Write an equation to find the mass of Sack A.
Answer:
1/8(A)+(3/4)(168-A)=76 is an equation to find the mass of A, the mass of A is 80 grams.
Step-by-step explanation:
What do we know?
Both sacks together are 168 grams. Therefore;
A+B=168
One eighth of sack A and three quarters of sack B is equal to 76 grams. Therefore;
1/8(A)+(3/4)B=76
Let's solve using the substitution method to find A. First, we need to isolate and then substitute B for an expression containing A.
A+B=168
B=168-A
Now that we have isolated B, we can substitute '160-A' for B in the other equation.
1/8(A)+(3/4)(168-A)=76
1/8(A)-3/4(A)+126=76
1/8(A)-3/4(A)+126=-50
-5/8(A)=-50

trapizoid figure STUV is scaled version of figure WXYZ. The scale factor of figure STUV to figure WXYZ is 3:1. If ST= 117 mm and SV= 153 mm, what is the length of side WZ?
Answer:
39mm
Step-by-step explanation:
Final answer:
Using the scale factor of 3:1, the length of side WZ from trapezoid WXYZ can be calculated by dividing the known length of side SV from trapezoid STUV by the scale factor. The length of WZ is found to be 51 mm.
Explanation:
If trapezoid STUV is a scaled version of trapezoid WXYZ with a scale factor of 3:1, we can use this scale factor to determine the length of side WZ given the lengths of ST and SV. To find the length of WZ, we divide the length of SV by the scale factor. Since SV = 153 mm and the scale factor is 3, we perform the division 153 mm / 3 to get 51 mm as the length of WZ.
A proportion is a mathematical statement that two ratios or fractions are equal. It is used to express the equality of two fractions that compare two numbers or quantities to each other. For example, if we have two fractions a/b and c/d, a proportion states that these two fractions are equivalent: a/b = c/d. Proportions are fundamental in various branches of mathematics and applications, including solving problems involving scales, maps, and ratios in real-life scenarios.

Complete the equation of the line through (-8, -2) and (-4, 6)
Answer:
Equation of line is given by:
[tex]y=2x+14[/tex]
Step-by-step explanation:
Given points:
[tex](-8,-2)\ and\ (-4,6)[/tex]
Slope of line [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is a point on the line
[tex]m=\frac{6-(-2)}{-4-(-8)}[/tex]
[tex]m=\frac{6+2}{-4+8}[/tex]
[tex]m=\frac{8}{4}[/tex]
∴ [tex]m=2[/tex]
Point-slope equation of line is given by:
[tex]y-y_1=m(x-x_1)[/tex]
where [tex](x_1,y_1)[/tex] is a point on the line and [tex]m[/tex] is slope of line.
Using point [tex](-8,-2)[/tex] and slope [tex]m=2[/tex] point-slope equation of line is given by:
[tex]y-(-2)=2(x-(-8))[/tex]
Simplifying.
[tex]y+2=2(x+8)[/tex]
Using distribution.
[tex]y+2=2x+16[/tex]
Subtracting 2 to both sides.
[tex]y+2-2=2x+16-2[/tex]
[tex]y=2x+14[/tex]
Thus, equation of line is [tex]y=2x+14[/tex]
Mrs. Kelly creates a garden. She buys 15 flowers and 3 bushes for a total cost of $160.32. Each bush costs $11.50 more than each flower. How much does each bush cost?
The cost of each bush is $ 18.49
Solution:Let "f" be the cost of each flower
Let "b" be the cost of each bush
Given that Mrs. Kelly buys 15 flowers and 3 bushes for a total cost of $160.32
15 flowers x cost of each flower + 3 bushes x cost of each bush = 160.32
[tex]15 \times f + 3 \times b = 160.32[/tex]
15f + 3b = 160.32 ----- eqn 1
Each bush costs $11.50 more than each flower
Cost of each bush = 11.50 + cost of each flower
b = 11.50 + f ------ eqn 2
Let us solve eqn 1 and eqn 2 to find values of "b" and "f"
Substitute eqn 2 in eqn 1
15f + 3(11.50 + f) = 160.32
15f + 34.5 + 3f = 160.32
18f = 160.32 - 34.5
18f = 125.82
f = 6.99Substitute f = 6.99 in eqn 2
b = 11.50 + 6.99 = 18.49
b = 18.49Thus the cost of each bush is $ 18.49
