Answer:

The area of the kite is 60 square feet

Step-by-step explanation:

The area of a kite is given as half multiplied by the product of the diagonals.

The longer diagonal measures 30 feet.

The shorter diagonal measures 4 feet.

The area of the kite is; [tex]\frac{1}{2}*30*4=60[/tex]

ANSWER

The area of the kite is 60 square feet

EXPLANATION

The area of a kite is half times the product of the diagonals.

The longer diagonal is 10+20=30 feet.

The shorter diagonal is 2+2 =4 feet.

The area of this kite

[tex] = \frac{1}{2} \times 30 \times 4[/tex]

This simplifies to,

[tex] = 60 {ft}^{2} [/tex]

Therefore the area of the kite is 60 square feet

Answer:

D. [tex]x=\frac{-4-\sqrt{31}}{3}[/tex] or  [tex]x=\frac{-4+\sqrt{31}}{3}[/tex]

Step-by-step explanation:

The given equation is:

[tex]3x^2+8x=5[/tex]

Divide through by 3;

[tex]x^2+\frac{8}{3}x=\frac{5}{3}[/tex]

Add the square of half the coefficient of x to both sides.

[tex]x^2+\frac{8}{3}x+(\frac{4}{3})^2=\frac{5}{3}++(\frac{4}{3})^2[/tex]

[tex]x^2+\frac{8}{3}x+\frac{16}{9}=\frac{5}{3}+\frac{16}{9}[/tex]

The left hand side is now a perfect square:

[tex](x+\frac{4}{3})^2=\frac{31}{9}[/tex]

Take square root

[tex]x+\frac{4}{3}=\pm \sqrt{ \frac{31}{9}}[/tex]

[tex]x=-\frac{4}{3}\pm \sqrt{ \frac{31}{9}}[/tex]

[tex]x=-\frac{4}{3}\pm \frac{\sqrt{31}}{3}[/tex]

D. [tex]x=\frac{-4-\sqrt{31}}{3}[/tex] or  [tex]x=\frac{-4+\sqrt{31}}{3}[/tex]

Answer:

333 in^3

Step-by-step explanation:

Circumference = pi *d

27 = pi*d

Replacing d with 2*r  ( 2 times the radius)

27 = pi * 2 * r

Divide each side by 2

27/2 = pi *r

13.5 = pi *r

Divide by pi

13.5/ pi = r

We want to find the volume of a sphere

V = 4/3 pi * r^3

V = 4/3 pi (13.5/pi)^3

  = 4/3 pi * (13.5)^3 / (pi^3)

  4/3 pi/pi^3  * (13.5)^3

   4/3 * 1/ pi^2 *2460.375

 3280.5 / pi^2

Let pi be approximated by 3.14

 380.5/(3.14)^2

Answer:

1923 cm²

Step-by-step explanation:

The surface area of a sphere is A = 4πr².

The first spherical beach ball has a radius of 24 cm:

A = 4π (24)²

A ≈ 7238 cm²

The second spherical beach ball has a radius 3 cm greater, or 27 cm:

A = 4π (27)²

A ≈ 9161 cm²

So the difference in area is:

9161 - 7238

1923 cm²

Answer:

1923 cm²

Step-by-step explanation:

Equation for the surface area of a sphere is 4πr².

The surface area of the bigger ball is (27²×4×π) = 2916π

The surface area of the smaller ball is (24²×4×π) = 2304π

The difference is 2916π-2304π = 612π

This is 1923 cm²

Answer:

80%

Step-by-step explanation:

According to the given data, the numbers 0 through 6 represent students who sent a text yesterday while the numbers 7 through 9 represent students who did not send a text yesterday.

Based on this key, we will calculate the number of students who sent the text yesterday and the number of students who did not sent the text yesterday.

The given data is: 62072, 34570, 80983, 04292, 83150, 36330, 96268, 14077, 77985, 13511

For each group we will identify how many students sent the text and how many students did not. According to the key, a number from 0 to 6 will be counted as a student who sent the text and a number from 7 to 9 will be counted as a student who did not send the text. Students who did not sent the text are made bold in the groups below.

62072:  4 students sent the text, 1 did not

34570:  4 students sent the text, 1 did not

80983:  2 students sent the text, 3 did not

04292:  4 students sent the text, 1 did not

83150:   4 students sent the text, 1 did not

36330:  All 5 students sent the text

96268:  3 students sent the text, 2 did not

14077:   3 students sent the text, 2 did not

77985:  1 student sent the text, 4 did not

13511:    All 5 students sent the text

We need to find the probability that 3 or more of a group of 5 students randomly selected will send a text today.

From the given groups, the number of groups where 3 or more students sent a text = 8

This represents our number of favorable or desired outcomes.

Total number of possible outcomes is the total number of groups = 10

Since, probability is defined as the ratio of number of favorable outcomes to total number of outcomes, based on the simulated data  the probability that 3 or more of a group of 5 students randomly selected will send a text today will be = [tex]\frac{8}{10}=0.80=80\%[/tex]

Thus, based on the simulated data there is 80% probability that 3 or more of a group of 5 students randomly selected will send a text today

Answer:

The answer is 80% or 4/5(;

Step-by-step explanation:

Janice should measure each wall's height and length to determine the square footage needed for painting and divide this by the coverage area of a gallon of paint to estimate the number of gallons she will need, ensuring to round up for any excess needed for touch-ups.

Janice's accuracy in estimating the amount of paint needed for her apartment is important to ensure that she neither runs out of paint before completing the job nor wastes money buying too much.

In general, paint cans are sold in one-gallon sizes, and a gallon typically covers around 350 to 400 square feet of wall space.

When calculating the paint needed, Janice should measure each wall's height and length to determine the square footage, considering any deductions for windows and doors.

Once she has the total square footage, she can divide by the coverage area of a gallon of paint to estimate the number of gallons needed. It's usually a good idea to buy a little extra for touch-ups, so round up to the nearest whole number.

As a review, understanding unit conversions is also pertinent.

For example, when converting miles to feet, ounces to pounds, or quarts to gallons, each conversion requires knowledge of the correct factors: 1 mile = 5,280 feet, 1 pound = 16 ounces, and 1 gallon = 4 quarts.

Such conversions are crucial in accurately determining quantities and can help avoid overestimating or underestimating the resources required for a task.

Final answer:

Janice needs to carefully calculate the amount of paint needed for her apartment by considering the square footage and paint coverage, possibly with a margin for extra paint. The painting job timing can be expressed with a linear equation T = 4 + 0.001S, where T is total time and S is square footage.

Explanation:

For Janice to estimate the amount of paint needed accurately, it's important that she does a careful calculation based on the square footage of her apartment walls and the coverage provided by each gallon of paint. The accuracy of this estimation will prevent the wastage of resources and ensure that the work does not halt due to the shortage of paint. However, it's also practical to consider buying an extra can to account for any unforeseen circumstances, as the estimation might have a margin of error.

Regarding the linear equation for the painting job: If it requires four hours of setup time plus one hour per 1,000 square feet, then we can express this as T = 4 + 0.001S, where T is the total time in hours and S is the square footage of the painting area. This linear equation will help to estimate the time needed for any given square footage.

Answer:

Option C is correct.

Step-by-step explanation:

Andy tested gemstones already = 30

Jacob tested gemstones already = 40

Total gemstones tested by Andy and Jacob already = 30+40 = 70

Andy continue to test gemstones per hour = 30

Jacob continue to test gemstones per hour = 25

Total gemstones tested by Andy and Jacob per hour = 30 +25 = 55

The total number of gemstones tested by Andy and Jacob after x hours will be: 55x

So, the equation will be: f(x) = 55x + 70

After 5 hours i.e. x =5

f(5) = 55(5) + 70

f(5) = 275 + 70

f(5) = 345

Andy and Jacob will have tested 345 gemstones in 5 hours.

So, Option C is correct.

Answer:

2,180 people

Step-by-step explanation:

Let

x-----> number of people at the book fair

we know that

1) 1/4 of the people bought 1 book each

(1/4)x=(5/20)x

2) 3/5 of the remaining  people bought 2 books each

The remaining people is (3/4)x

so

(3/5)(3/4)x=(9/20)x

3) the rest of the people bought 3  books each

The rest of the people is x-(5/20)x-(9/20)x=(6/20)x

The linear equation that represent this situation is

(1)*(5/20)x+(2)*(9/20)x+(3)*(6/20)x=4,469

(5/20)x+(18/20)x+(18/20)x=4,469

(41/20)x=4,469

x=4,469*20/41

x=2,180 people

Step-by-step explanation:

her wage is $4.00 + s*0.5 so 7.25-4> s*.5== 3.25 > s*.5 == 6.5 > s

The inequality for the given information can be written as 6.5 > s.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

A lifeguard at a swimming pool gives one-hour swim lessons to children in the morning before the pool is open to the public. She earns four dollars per class and fifty cents per swimmer. The minimum wage in her state is $7.25.

The inequality can be written as:-

$4.00 + ( s x 0.5 )

7.25-4 > ( s x 0.5 )

3.25 > ( s x 0.5 )

6.5 > s

Step-by-step explanation:

The answer is -3

Because

Check the picture below.

so the figure is really just 3 triangles and one square, we can simply get the area of each shape and sum them up, and that's the area of the composite

[tex]\bf \stackrel{\textit{green triangle}}{\cfrac{1}{2}(9)(3.5)}+\stackrel{\textit{brown triangle}}{\cfrac{1}{2}(2)(2)}+\stackrel{\textit{purple square}}{(2\cdot 2)}+\stackrel{\textit{pink triangle}}{\cfrac{1}{2}(5)(2)} \\\\\\ 15.75+2+4+5\implies 26.75[/tex]

Answer:

Step-by-step explanation:

Look at the picture.

We have

the right traingle with the legs a = 3.5 and b = 2 + 2 + 5 = 9

the trapezoid with the bases b₁ = 2 + 2 + 5 = 9, b₂ = 5 and the height h = 2.

The formula of an area of a right triangle:

[tex]A=\dfrac{ab}{2}[/tex]

Substitute:

[tex]A=\dfrac{(3.5)(9)}{2}=15.75[/tex]

The formula of an area of a trapezoid:

[tex]A=\dfrac{(b_1+b_2)h}{2}[/tex]

Substitute:

[tex]A=\dfrac{(9+2)(2)}{2}=11[/tex]

The area of the shape:

[tex]\bold{A=15.75+11=26.75}[/tex]

Answer:

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

[tex]CB'=C'B'=2[/tex]

[tex]B'B=6[/tex]

[tex]CB=CB'+B'B=2+4=6[/tex]

The scale factor of a figure is

[tex]k=\frac{\text{Length of any side of image}}{\text{Length of corresponding side of preimage}}[/tex]

[tex]k=\frac{C'B'}{CB}[/tex]

[tex]k=\frac{2}{6}[/tex]

[tex]k=\frac{1}{3}[/tex]

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

A. [tex]g(x)=(x-4)^2[/tex]

Step-by-step explanation:

The graph of [tex]f(x)=x^2[/tex] is transformed to obtain the graph of g(x).

We can see from the diagram that, f(x) is shifted 4 units to the right to obtain the graph of g(x).

Therefore [tex]g(x)=f(x-4)[/tex].

Hence the equation of g(x) is

[tex]g(x)=(x-4)^2[/tex]

The correct answer is A.

The equation of the graph of g(x) is g(x) = (x - 4)²

From the graph shown, we can see that the f(x) = x² as shown is shifted   4 units to the right to obtain the graph of g(x).

Then, we have that this shift can be achieved by replacing x in the equation of f(x) with x - 4 to represent the horizontal shift.

We have the equation of the graph of g(x), to be;

g(x) = (x - 4)²

This equation represents a horizontal shift of the graph of f(x) by by 4 units to the right, as g(x) remains the same shape f(x) but is  shifted horizontally to the right by 4 units.

Answer:

the equation of the perpendicular bisector of segment AB is y = -2x + 7

Step-by-step explanation:

Going from B(-1, 4) to A(3, 6), x increases by 4 and y increases by 2.  Thus, the slope of this line is m = rise / run = 2/4, or 1/2.

Any line perpendicular to the one joining A and B has a slope which is the negative reciprocal of 1/2:  that'd be -2.

                                                               3 - 1       6 + 4

The midpoint of line segment AB is ( --------- , ---------- ), or (1, 5)

                                                                  2            2

Thus, the perpendicular bisector passes through the midpoint (1, 5) and has slope -2:

Starting from y = mx + b, we get  5 = -2(1) + b, or 7 = b, and so the equation of the perpendicular bisector of segment AB is

y = -2x + 7
