Subtract the sum of three test scores from the product of 75 and 5 .
I think

Answer:

Subtract the sum of the three test scores from the product of 75 and 5, and then divide the result by 2.

Step-by-step explanation:

From the question:

100, 70, 85 on three of her five tests

Total number of test = 5

mean of the five scores is 75

mean = average of the five scores

Average score = Total score / total number of test

Total score = Average score * total number of test

= 75*5 =375

to find remaining two tests' scores

Total score - the 3 scores from question

= 375 - 100 - 70 - 85

=120

If u want to find the score of each of the unknown test

From question:

She could not remember the other two scores, which were the same.

Thus,

The score of one test

= 120/ 2

=60

Ed is building a model of a house with a flat roof, as shown in the diagram. There is a chimney through the roof. Ed will cover the roof with square tiles.

If the area of each tile is 1 square inch, how many tiles will he need?

Answers

Answer:

Step-by-step explanation:

3x4

You will need to find the area first so 50in x 40in =2,000in

Then find the area the chimney takes up. 4in x 3in = 12in

2,000in - 12in =1,988 tiles for the roof.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 30 inches, and the length of the base is 10 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.

Answers

Perimeter = 78.7 inches
Step-by-step explanation:
From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;
= +
= +
=841 + 81
= 922
hyp =
= 30.3645
The perimeter of the triangle can be determined as;
perimeter = + +
= 30.3645 + 18 + 30.3645
= 78.729
The perimeter of the triangle = 78.7 inches

The perimeter of the triangle is 70.82 inches.

Given as :

The length of the altitude is 30 inches, and

The length of the base is 10 inches

What is right triangle?

Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.

Let, perpendicular = 30 and base = 5

According to Pythagoras theorem,

A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

perpendicular² + base² = hypotenuse²

Substitute the values,

30² + 5² =  hypotenuse²

900 + 25 =  hypotenuse² or

hypotenuse² = 925

hypotenuse = √925

hypotenuse = 30.41

The perimeter of the triangle can be determined as:

Perimeter of the triangle = l₁ + l₂ + l₃

Perimeter of the triangle = 30.41+ 10 + 30.41

Perimeter of the triangle = 70.82

Hence, the perimeter of the triangle is 70.82 inches.

Because the radius is 4.5 inches we use the area formula for a circle ( pi * radius squared) to find the answer so

4.5 * 4.5 * 3.14 which will equal 63.585 inches squared

Hope this helps

Answer:

D. 4.5

The Area is 63.585

Step-by-step explanation:

So the diameter is twice the size of the "r" or radius so divide 9 by 2

which is 4.5

The formula for a circle is πr^2

4.5 times itself is 20.25

times pi or 3.14 is 63.585
