Answer:

The area of the shaded region is 24 cm^2.

Step-by-step explanation:

1. find the area of the rectangle

A = 8*4

A = 32 cm^2

2. find the area of the triangle

A = (4*4)/2

A = 8 cm^2

3. to find the area of the shaded region, subtract the area of the triangle from the area of the rectangle

A = 32 - 8

A = 24 cm^2

Answer: the area of the shaded region is 24 cm^2.

Answer:

Answer is -8 I used Mathwat

Tyrone is working with two other students to build a border around the school’s triangular garden. Each student brought in one side of the border, but they all used different units to measure the side lengths. The first side is 312 inches long, the second side is 20 feet long, and the third side is 12 yards long. If the measurements need to be in feet, will the three border pieces make a right triangle?

Convert the first side into feet using a proportion.

Answers

Answer:

NO, the these three border pieces will not make a right triangle

Step-by-step explanation:

Perform the necessary conversions:

1.  312 in converts to

      312 in       1 ft

     ----------- * ------- = 26 ft

        12 in         1

2.  20 ft

3.  12 yd converts to

         12 yd         3 ft

       ------------- * --------- = 36 ft

            1 yd             1

So the three different side lengths are 26 ft, 20 ft and 36 ft.

For the three pieces to make a right triangle, these measurements must satisfy the Pythagorean Theorem:

26² + 20² = 36², or 1296

676 + 400 = 1076

The Theorem is NOT satisfied, and so NO, the these three border pieces will not make a right triangle.

Answers

Answer:

I'm sorry I have no clue what this is. What grade are you in? I'm in seventh and  I have never learned anything like this lol.

Step-by-step explanation:



3)first you count the sides
There are 8 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(8-2)*180
=6*180=1080

To find the measure of one interior angles divide the answer by the number of sides
900/8=112.5



4)first you count the sides
There are 7 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(7-2)*180
=5*180=900

To find the measure of one interior angles divide the answer by the number of sides
900/7= 128.57

You can see the picture for the steps but I’m sure the answer is -72

Answer:

x = -72

Step-by-step explanation:

Using algebra:

⇒ [tex]-\frac{x}{8} -11 = 2[/tex]  (First add 11 to both sides of "=")

⇒ [tex]-\frac{x}{8} =9 (11 + -2)[/tex] (The multiply both sides by "8")

⇒ [tex]-x = 9*8[/tex] (Lastly the answer is 72 when x-value is negative, so when x-value will be positive the answer will be opposite of 72 which is -72)

⇒ [tex]x = -72[/tex]

3. Consider the following expressions. EVALUATE each expression AND
EXPLAIN WHY they have different answers.
2 points
6 + 32 and (6 + 3)?
Can you please help me with both of does problems

Answers

the first one = 12 and the second one = 18.
the reason why they have different answers is because of PEMDAS.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

For the first equation we gave to multiply the exponent (2) to the number (3) because that’s the order of PEMDAS. So, 3x2=6 then + 6=12.

For the second equation there are parentheses, which means we solve the equation inside the parentheses first because of PEMDAS. So, 6+3=9 then x 2 =18.

They have different answers because they are ordered in different ways . PEMDAS controls the order we solve equations in.

The grocery store is mile from Katie’s house and the gas station is 0.5 mile from Katie’s house.
Which comparison of these distances is both true and correctly justified?
A. Because 0.5 < , the gas station is closer than the grocery store.
B. Because 0.5 < , the grocery store is closer than the gas station.
C. Because < 0.5, the gas station is closer than the grocery store.
D. Because < 0.5, the grocery store is closer than the gas station.

Answers

Answer:

A is the answer i got a 100 on my test yay

Step-by-step explanation:

The correct answer is:

A. Because 0.5 < 5/6, the gas station is closer than the grocery store.

Given that the grocery store from Katie’s house is 5/6 miles away and the gas station is 0.5 miles away, we need to compare the distances of both the places and choose the correct option,

To compare the distances accurately, we need to convert the fraction 5/6 into a decimal.

To do this, we divide 5 by 6:

5 ÷ 6 = 0.8333...

Now let's compare the distances:

0.5 is less than 0.8333..., so we can conclude that the gas station is closer to Katie's house than the grocery store.

Therefore, the correct answer is:

A. Because 0.5 < 5/6, the gas station is closer than the grocery store.
