Answer:
A
Step-by-step explanation:
the formula is A=πr2!!! So since diameter is 10, 10/2 = 5 that means 5 is the radius, 5^2 = 25, 25*π = 78.54

28/40
1:2
110:19
180
$10
Step-by-step explanation:
For 1-8, they are ratios. Ratios can be expressed in many two major ways. Fractions, and the answer i put. Ratio is like division. Therefore, you divide it by something.
Let’s bring question 8 for example,
It says: There are 110 students on a bus filled with 129 people. What is the ratio of students to teachers?
The given fact is that there is 110 students and 129 in total. It means that there is 19 adults, since 129-110 is equal to 19. Then, it’s looking for the ratio of students to teacher. The answer would be 110:19, 110/19, or 110 divided by 19
For question 9, it asks how much oranges Lisa will use if she serves 800 people.
It takes 9/40 oranges per servings. To solve this, we need to multiply 9/40 by 800, which is equal to 180(9/40*800=7200/40=180)
For question 10, we have to find how much it costs for a single ring.
if 5 rings cost $1, it means that it costs $0.2 per ring, since 1/5 is equal to 0.2. Then, we have to multiply it by 50. 0.2 time 50 is equal to 10.
I hoped this helped
I only know these ones tho...
1. 60:13 (You arrange it to the order the question asked in this case they asked for "the ratio of students to teachers" so I did that)
2. 16:56 (You are supposed to add them like this to get the ratio of students 40 + 16 = 56)
3. 11:16 (You arrange them in the order that the question asked for your example was "What is the ratio of calico kittens to non-calico kittens" so I arranged them like that)
4. 10:17 (You are supposed to add them like this to get the ratio of attendees 7 + 10 = 17)
5. 2:7 (What we do is that because they told us there are 2 brindle puppies and we know the number of puppies is 9 so we minus the 2 brindle puppies from 9. To find the amount of non-bridle puppies we do this 9 - 2 = 7)
6. 28:40 (You are supposed to add them like this to get the ratio of attendees to teenagers 28 + 12 = 40)
7. 11:33 (You are supposed to add them like this to get the ratio of total cakes 22 + 11 = 33)
8. 110:19 (What we do is that because they told us there are 110 students and we know the number of people is 129 so we minus the 110 students from 129 to find the ratio of students to teachers we do this 129 - 110 = 19)

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

Step-by-step explanation:
Consider the line y=2/3x-4 a line perpendicular to the graph of the line would have a slope of
Answer:
-3/2
Step-by-step explanation:
The slope of a line is its gradient. The equation shown here is y=mx+c. m is the gradient, therefore the gradient is 2/3. To find the perpendicular gradient you flip the sign (+ turns to -, - turns to +) and you switch numerator with the denominator.

Answer:
Equation:x+70=8x and both angles measure 80 degrees.
Step-by-step explanation:
Equation:x+70=8x
That is because vertical angles are congruent.
x+70=8x
-x -x
70=7x
x=10
Both angles measure 80 degrees.

15 unique triangles can be made.
Step-by-step explanation:Given : A triangle has one angle measures 60° and another angle is an obtuse angle .
To find : How many unique triangles can be made ?
Solution : Since we know, that sum of all three angle of a triangle is 180°,
One angle is 60°,
Second angle is obtuse angle(means angle is greater than 90°) then the third angle is acute angle(means less than 90°) .
60 + O + A = 180°
O + A = 180 - 60°
= 120°
90 + A + A = 120°
A + A = 120 - 90
= 30°
This means the third angle is sum of two acute angle is 30°.
So, The possible sum is (1+29),(2+28),(3+27),........(15+15)
Therefore, The possible ways the triangle can form is 15 ways.
Hence, 15 unique triangles can be made.
A simple and a similar answer -
More than 2 unique triangles can be made where on angle measure 60 degrees and another angle is obtuse.

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)
Hope my answer helps you.

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
The 2nd question-Kevins weekly salary is $865. He receives a 25% raise. How can kevin find his new weekly salary? select all that apply
A. divide 865 by 0.25
B. divide 865 by 1.25
C. multiply 865 by 0.25
D. multiply 865 by 1.25
E. add 865 and 1/4 of 865
F add 865 and 1 1/4 of 865
last question im gonna make on another one of these
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.
