What are the values of a and b?
dangina [55]

Answer:

D

Step-by-step explanation:

These two triangles are similar triangles. The two angles marked are the same and the two angles at the intersection where you see the square are also the same, making it clear that the last angle must be the same as well.

Therefore,

length 8 from the top triangle is similar to length 6 on the bottom triangle,

length 10 from the top is similar to b on the bottom triangle,

length 6 from the top is similar to a on the bottom.

To find the ratio of similarity, you would compare the length 8 to length 6, and divide them. 8/6 = 1.33333

Now that you've found the proportionality constant, you divide the other two lengths on the top triangle with the constant to get <em>b </em> and <em>a</em>.

b = 10/1.3333 = 7.5

a = 6/1.3333 = 4.5

Therefore, the answer is D: a = 9/2, b = 15/2.

In mr. wilson's geometry class, 12 of the students received a's and 20 received b's. in his statistics class, 11 of the students
Ainat [17]

In (A) statistics class Wilson's students earn a higher ratio of a's to b's.

<h3>What are ratios?</h3>
  • A ratio in mathematics describes how many times one number contains another.
  • For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six.
  • Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.

To find the higher ratio:

Given -

  • Geometry class = a:b = 12:20 = 3:5
  • Statistics class = a:b = 11:15

As we can observe that 3:5 < 11:15.

Therefore, in (A) statistics class Wilson's students earn a higher ratio of a's to b's.

A rectangle flower bed had a total area of 40 square yards. If it was 4 yards wide, how long was it?
Pie
Area=wide times long
area=40
4=wide

40=4 times long
divide both sides by 4
10=long


10 yd long

The width of a piece of paper is 8.5in the length is 11in and the thickness is 0.0037inches there are 2700sheets sitting in a ca
Musya8 [376]

Answer:

934.2 in³

Step-by-step explanation:

The following data were obtained from the question:

Width (W) = 8.5 in

Length (L) = 11 in

Thickness (T) = 0.0037 in

Number of paper = 2700 sheets

Volume occupied by the 2700 sheets of paper =?

Next, we shall determine the volume of 1 sheet of paper. This can be obtained as follow:

Width (W) = 8.5 in

Length (L) = 11 in

Thickness (T) = 0.0037 in

Volume (V) =?

Volume = Length × Width × Thickness

Volume = 11 × 8.5 × 0.0037

Volume = 0.346 in³

Thus, the volume of 1 sheet of paper is 0.346 in³

Finally, we shall determine the volume occupied by the 2700 sheets of paper as follow:

Volume of 1 sheet of paper = 0.346 in³

Volume of 2700 sheets of paper =?

1 sheet of paper occupied 0.346 in³.

Therefore, 2700 sheets of paper will occupy = 0.346 × 2700 = 934.2 in³

Thus, the volume occupied by the 2700 sheets of paper is 934.2 in³.
