Answer:

A.) The two tiles are similar because is 1 : 3 and is also 1 : 3.

Step-by-step explanation:

If you can calculate the sides of each tile you can get the ratio from the base to the height, in this case the side j-k measures 1 unit, and the side J-M measures 3, in this case the aspect ratio is 3:1.

And in the second tile the side P-Q is 2 units long, and the side P-S is 6 units long, now the aspect ratio would be: 6:2, if you reduce this it´d be 3:1.

Since both have an aspect ratio of 3:1 they are similar.

What is the product of -4 and 8.1?<br><br> a) -32.4<br> b) -12.1<br> c)12.1<br> b) 32.4

Sergeeva-Olga [200]

Option A

<u>Answer: </u>

The product of -4 and 8.1 is -32.4

<u>Solution: </u>

When we multiply a negative number with a positive number we get the resultant product as a negative number.

Here we have to multiply - 4 which is a negative number and 8.1 which is a positive number.

To simplify the multiplication calculation we can write 8.1 as 8+0.1 and then multiply 4 with both 8 and 0.1

-4 $\times$ 8.1 = -4 $\times$ (8+0.1)

⇒ -4 $\times$ 8.1 = -4 $\times$ 8 – 4 $\times$ 0.1 [Multiplying 4 with 8 and 0.1]

⇒ -4 $\times$ 8.1= -32 - 0.4

⇒ -4 $\times$ 8.1= - 32.4

Thus the product of -4 and 8.1 is -32.4

The mean (rounded to the nearest tenth if needed) of the following data set is: 30, 29, 40, 51, 39, 33, 24, 60, 40, 35, 58

bekas [8.4K]

Mean is just the average so to calculate the average just add up all the data and divide it by the number of data.
so it's gonna be
(30+29+40+51+39+33+24+60+40+35+58) / 11
= 39.9 (corrected to the nearest tenth)

Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)

Mkey [24]

<h2><u>Polynomial Function</u></h2>

<h3>Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)</h3>

To determine the answer, substitute the given value to the function and simplify.

h(x) = 3x² + 2 - 2x; h(-2)
h(-2) = 3(-2)² + 2 - 2(-2)
h(-2) = 3(4) + 2 + 4
h(-2) = 12 + 2 + 4
h(-2) = 14 + 4
h(-2) = 18

<u>Answer:</u>

<u>18</u> is the answer.
