40 (16) = 640
The area of the two semicircles is
2x (16/2 x 16/2 x h x 1/2) which is 64h and when h =3.14 and 64 x 3.14 = 200.96 and when u minus it it will give u 439.04ft^2
439.04 ft² (Approximately)
Step-by-step explanation:The Length of the Gymnasium court = 40 ft
The Breadth of the Gymnasium court = 16 ft
Total area of the Gymnasium court = Length * Breadth
= 40 * 16
= 640 ft²
Diameter of the circles = 16 ft
Radius of the circles = Diameter / 2
= 16 / 2
= 8 ft
Area of a semicircle = πr² / 2
= 3.14 * 8² / 2
= 3.14 * 64 / 2
= 3.14 * 32
= 100.48 ft² (Approximately)
Number of semicircles = 2
Area of all the semicircles = Area of semicircle * Number of semicircles
= 100.48 * 2
= 200.96 ft² (Approximately)
Area of shaded region = Area of rectangle - Area of semicircles
= 640 - 200.96
= 439.04 ft² (Approximately)

The dimensions of the new rectangle after the dilation would be given as follows:
12 cm.4.5 cm.What is a dilation?A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.
The dimensions of the original rectangle are given as follows:
4 cm.1.5 cm.The scale factor is given as follows:
k = 3.
Hence the dimensions of the dilated rectangle are given as follows:
3 x 4 = 12 cm.3 x 1.5 = 4.5 cm.More can be learned about dilation at brainly.com/question/3457976

The 1st question-Elena is organizing her craft supplies. She estimates that her jars will fit 1,000 buttons or 50 large beads.they actually fit 677 buttons or 22 large beads. does Elena's estimate about the buttons or her estimate about the large beads have less percent error> to the nearest percent, how much less? show your work

Answer:
C
Step-by-step explanation:
0.25 x 865
Answer:
Step-by-step explanation:
1,,,To determine which estimate has a lower percent error, we need to calculate the percent error for each estimate and compare them.
Percent error can be calculated using the formula:
percent error = [(actual value - estimated value) / actual value] x 100%
For the buttons estimate:
percent error = [(677 - 1000) / 1000] x 100% = -32.3%
For the large beads estimate:
percent error = [(22 - 50) / 50] x 100% = -56%
Since the percent error for the large beads estimate (-56%) is larger than the percent error for the buttons estimate (-32.3%), Elena's estimate about the buttons has less percent error.
To determine how much less, we can subtract the two percent errors:
percent error difference = (-56%) - (-32.3%) = -23.7%
Rounding to the nearest percent, Elena's estimate about the buttons has 24% less percent error than her estimate about the large beads. 2,,,w weekly salary after a 25% raise, we can multiply his current weekly salary by 1.25 (which represents a 125% increase, since 100% + 25% = 125%). So, the correct answers are:
D. Multiply 865 by 1.25.
E. Add 865 and 1/4 of 865.
The steps for each option are:
A. Divide 865 by 0.25: This will not give Kevin's new salary after the raise. Instead, it will give the amount of the raise itself (since 25% of 865 is $216.25). To find the new salary, we need to add the raise amount to his original salary.
B. Divide 865 by 1.25: This will also not give Kevin's new salary after the raise. Instead, it will give his salary before the raise (since 865 ÷ 1.25 = 692, which is 100% of his original salary). To find the new salary, we need to multiply his original salary by 1.25.
C. Multiply 865 by 0.25: This will also give the amount of the raise itself (since 25% of 865 is $216.25). To find the new salary, we need to add the raise amount to his original salary.
D. Multiply 865 by 1.25: This will give Kevin's new weekly salary after the 25% raise.
E. Add 865 and 1/4 of 865: This is equivalent to multiplying 865 by 1.25, so it will also give Kevin's new weekly salary after the 25% raise.
F. Add 865 and 1 1/4 of 865: This is not a correct way to calculate Kevin's new weekly salary after the raise, since 1 1/4 of 865 is not a valid percentage increase.
