Answer:
c: 1,335 yd³
Step-by-step explanation:
The formula for volume of a cylinder is V = πr²h where r is the radius of the base circle, and h is the height of the cylinder
We are given r = 5, and h = 17. Plug them in and solve for V...
V = π(5²)(17)
V = π(25)(17)
V = 425π
V = 425(3.14) = 1,334.5 yd³,
so 1,335 yd³ rounded to the nearest cubic yard

How many flowers, spaced every 3 in., are needed to surround a circular garden with a 150-ft radius? Use 3.14 for pi.
Final answer:
To surround a circular garden with a 150-ft radius every 3 inches with flowers, calculate the garden's circumference using the formula C = 2πr, convert it to inches and divide by the spacing. You'd need approximately 3,768 flowers.
Explanation:
To calculate the number of flowers needed to surround a circular garden with a 150-ft radius spaced every 3 inches, you have to find the circumference of the garden and then determine how many 3-inch spaces fit along that circumference.
First, find the circumference (C) of the garden using the formula C = 2πr, where π (pi) is approximately 3.14 and r is the radius. In this case:
C = 2 × 3.14 × 150 ftC = 2 × 3.14 × 150 ft = 942 ftConvert 942 ft into inches because the spacing is in inches:
C = 942 ft × 12 in/ft = 11,304 inNow, divide the circumference in inches by the spacing to get the number of flowers:
Number of flowers = 11,304 in / 3 in per flowerNumber of flowers = 3,768Therefore, you would need 3,768 flowers to surround the garden spaced every 3 inches.

Help me solve plz. Use substitution to check. y - 4 = 36
Answer:
y = 40
Step-by-step explanation:
Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides.
y - 4 = 36
y - 4 (+4) = 36 (+4)
y = 36 + 4
y = 40
Check. Substitute 40 for y.
Plug in 40 for y.
y - 4 = 36
(40) - 4 = 36
36 = 36 (True).

Step-by-step explanation:
Answer:
The correct option is B.
Step-by-step explanation:
From the given figure it is clear that triangle LMN is a right angled triangle.
According to Pythagoras theorem: In a right angled triangle
[tex]hypotenuse^2=perpendicular^2+base^2[/tex]
In triangle LMN,
[tex]LN^2=LM^2+MN^2[/tex]
[tex](\sqrt{20})^2=x^2+(x-2)^2[/tex]
[tex]20=x^2+x^2-4x+4[/tex]
[tex]20=2x^2-4x+4[/tex]
Subtract 20 from both sides.
[tex]0=2x^2-4x+4-20[/tex]
[tex]0=2x^2-4x-16[/tex]
Taking out common factors.
[tex]0=2(x^2-2x-8)[/tex]
Splitting the middle term we get
[tex]0=2(x^2-4x+2x-8)[/tex]
[tex]0=2(x(x-4)+2(x-4))[/tex]
[tex]0=2(x-4)(x+2)[/tex]
Using zero product property we get
[tex]x-4=0\Rightarrow x=4[/tex]
[tex]x+2=0\Rightarrow x=-2[/tex]
The value of can not be negative because side of a triangle is always positive. So, the value of x is 4.
Therefore the correct option is B.

The point slope form of the eqaution of the line that passes through (-5,-1) and (10, -7) is y+7= -2/5 (x - 10) what is the standard form of the equation for this line 2x-5y=-15 2x-5y= -17 2x+5y=-15 2x+5y=-17
Answer:
2x + 5y = -15Step-by-step explanation:
The standard form of an equation of a line:
[tex]Ax+By=C[/tex]
We have the equation in point-slope form:
[tex]y+7=-\dfrac{2}{5}(x-10)[/tex]
Convert it to the standard form:
[tex]y+7=-\dfrac{2}{5}(x-10)[/tex] multiply both sides by 5
[tex]5y+35=-2(x-10)[/tex] use the distributive property a(b + c) = ab + ac
[tex]5y+35=(-2)(x)+(-2)(-10)[/tex]
[tex]5y+35=-2x+20[/tex] subtract 35 from both sides
[tex]5y=-2x-15[/tex] add 2x to both sides
[tex]2x+5y=-15[/tex]

Step-by-step explanation:
Question 1: If they're not similar it can't be the same shape but if they have the same corresponding angles it has to be either a rectangle or a square. It can't be a rectangle so it must be a square.
Question 2: Can't be similar so it can't be the same shape. The only two shapes with side lengths proportional are the parallelogram and the rectangle. It can't be the rectangle so it must be the parallelogram.
Question 3: If it's similar it has to be the same shape so the answer must be the rectangle.

The first step you have to get it into this form
a[tex]x^{2}[/tex] + bx + c
So that would be
3x[tex]x^{2}[/tex] + 1x + c
we do not know what c is
we have to get x by it self from 3x[tex]x^{2}[/tex] so first you have to square it now we are at 9x
9x divided by 9 that would leave us with x
so our finished product is x + 1x + c
we have to get x by itself from 1x so we do exactly what we just did 1x divided by 1x would leave us with x
x + x=[tex]x^{2}[/tex] + x
[tex]x^{2}[/tex] + c is the finished product which is your answer
Line jk passes through points j(-4,-5) and k(-6,3). What is the value of b
Answer:
b = -21Step-by-step explanation:
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
b - y-intercept → (0, b)
We have the points J(-4, -5) and K(-6, 3).
The points J, K and y-intercept A(0, b) are collinear. Therefore the slope of JA and KA are the same.
We have the equation:
[tex]\dfrac{b-(-5)}{0-(-4)}=\dfrac{b-3}{0-(-6)}\\\\\dfrac{b+5}{4}=\dfrac{b-3}{6}\qquad\text{cross multiply}\\\\6(b+5)=4(b-3)\qquad\text{use the distributive property}\\\\6b+30=4b-12\qquad\text{subtract 30 from both sides}\\\\6b=4b-42\qquad\text{subtract 4b from both sides}\\\\2b=-42\qquad\text{divide both sides by 2}\\\\b=-21[/tex]

m∠QPR = 80°Step-by-step explanation:
Look at the picture.
We know: the sum of the measures of the angles of the triangle is equal to 180 °.
Therefore
In ΔTQR we have the equation:
[tex]\alpha+\beta+130^o=180^o[/tex] subtract 130° from both sides
[tex]\alpha+\beta=50^o[/tex]
In ΔPQR we have the equation:
[tex]2\alpha+2\beta+m\angle QPR=180^o[/tex]
[tex]2(\alpha+\beta)+m\angle QPR=180^o[/tex]
Substitute from the first equation
[tex]\alpha+\beta=50^o[/tex]
[tex]2(50^o)+m\angle QPR=180^o[/tex]
[tex]100^o+m\angle QPR=180^o[/tex] subtract 100° from both sides
[tex]m\angle QPR=80^o[/tex]

On a local sports team, 20% of 50 players are left-handed. How many left-handed players are there?
Answer:
10
Step-by-step explanation:
20%x50=10
Final answer:
To find the number of left-handed players on the sports team, 20% of the 50 total players is calculated, which equals 10 left-handed players.
Explanation:
To calculate the number of left-handed players on a local sports team where 20% of the players are left-handed, you need to apply the percentage to the total number of players. If there are 50 players in total, you would calculate 20% of 50:
Convert the percentage to a decimal by dividing it by 100. So, 20% becomes 0.20.
Multiply this decimal by the total number of players to find the number of left-handed players: 0.20 imes 50 = 10.
Therefore, there are 10 left-handed players on the team.
What is the surface area of this cylinder to the nearest integer?
57 in2
75 in2
132 in2
250 in2
Answer:
131.95in^2
Step-by-step explanation:
The formula for surface area in a cylinder is A = 2pi*r*h + 2pi*r^2
The radius in this cylinder is half the diameter in the cylinder which is 6, so the radius is 3.
The height is 4 since it is given.
Then we just plug the values into the equation and we get a surface area around 131.95in^2

Jessica loves to read. She reads at a speed of 3 pages per minute. How many pages can she read in 2 hours? (First concert 2 hours into minutes)
Jessica, who reads at a speed of 3 pages per minute, can read 360 pages in 2 hours.
Explanation:The subject of this question is mathematics, answered by a simple multiplication operation. Jessica loves to read and reads at a speed of 3 pages per minute. We know that there are 60 minutes in an hour, so in 2 hours, there are 2 * 60 = 120 minutes. Now, if Jessica reads 3 pages per minute, in 120 minutes, she would read 120 * 3 = 360 pages. Therefore, Jessica can read 360 pages in 2 hours at her reading speed.
