Answer:

110 degrees

Step-by-step explanation:

ABL + ABC = 180

BED + ABC = 180 ( BED = ABL )

BED = 180 - ABC = 180 - 70 = 110

for question 1

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Height = 15 cm

Using the formula

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

Area of base = 7× 5/2= 17.5 cm²

Perimeter of base = (7+7+7) = 21 cm

Surface area = 2B + Ph

Surface area of prism = 2×17.5+ 21×10 = 245cm²

Volume = Bh = 17.5×10 = 175 cm³

Answer: 12 degrees or 11 5/5 or 60/5

Step-by-step explanation:

Since the temperature is rising 2 2/5 per 1/5 of an hour we just need to multiply 2 2/5 times 5 because 5/5 would equal the whole hour. In order to multiply easier you can change 2 2/5 to an improper fraction by multiplying the whole number with the denominator and then adding the numerator. Which you should get 12/5 next change 5 to a fraction which would be 5/1. 5 times 12 is 60 and 5 times 1 is 5. You get 60/5 which if divided is 12.

For the number line you just have to find 1/5 and 2 2/5 on it and mark it.

Answer:

LCD=5 Final answer= 5/5 -> 5/1 -> to 5

Step-by-step explanation:

First, find the LCD(least common denominator) which is 5. This is done listing the multiples of each number in this case the lowest number is 5.

3/5 will stay the same but for 1/10 you need to convert it to the fraction 2/5 Next add the fractions together to get 3/5 + 2/5 = 5/5 of 5/1 or just 5

Answer:

LCD=5 Final answer= 5/5 -> 5/1 -> to 5

Answer:

A B and E

Step-by-step explanation:

To figure out the correct answer we must solve for the area. We do this with length x width.

Square Area:

32 * 32 = 1024

Rectangle Area:

48 * 20 = 960

From this we know, the rectangle has a smaller area of 960 inches, this means that A and B are correct, we also know that E is correct the difference betweenn 1024-960 = 64.

The solution is Option A

The ratio of length : width : thickness of the plank is 1 : 12 : 4

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the length of the plank = 1 cm

The width of the plank = 12 cm

The thickness of the plank = 4 cm

Now , the proportion is given as

The ratio of length : width : thickness of the plank = 1 : 12 : 4

Therefore , the value of A is 1 : 12 : 4

Hence , the proportion is  1 : 12 : 4

x = 67°

Same-side interior angles are supplementary.

r = 2°

     The little box represents 90 degrees, meaning that these angles are complementary.

Step-by-step explanation:

You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.

The speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...

  A speed - B speed

  45000 mi/(5 h) - 79200 mi/(18 h) = 4600 mi/h

Explorer B travels 4600 fewer miles in an hour than Explorer A.

Answer:

The speed of the wind is 12 miles per hour.

Explanation:

Let's call the speed of the plane in still air "p" and the speed of the wind "w".

From the given information, we know that:

756 miles = 7 hours * (p + w) (with the wind)

756 miles = 9 hours * (p - w) (against the wind)

We can simplify these two equations by dividing both sides by 7 and 9, respectively:

108 miles/hour = p + w

84 miles/hour = p - w

Now we can use a system of equations to solve for p and w:

p + w = 108

p - w = 84

Adding these two equations, we get:

2p = 192

Dividing by 2, we get:

p = 96

So the speed of the plane in still air is 96 miles per hour.

To find the speed of the wind, we can substitute p = 96 into either of the simplified equations:

p + w = 108

96 + w = 108

Subtracting 96 from both sides, we get:

w = 12

So the speed of the wind is 12 miles per hour.

Therefore, the speed of the plane in still air is 96 miles per hour and the speed of the wind is 12 miles per hour.

Answer:

Supplies used:

a. 12 feet of wood used

b. 3.5 bundles used, .5 left

Areas:

a. .75 ft

b. 1.61 ft

c. 2.625 ft

d. 3.33 ft (3 1/3 ft)

Paint:

8 ounces

Step-by-step explanation:

For the supplies used, we can multiply 16 by 3/4 to get 48/4, which simplifies to 12

Then for the shingles we can multiply 4 by 7/8 to get 28/8, which simplifies to 3.5

To get the areas, we just have to multiply the length and width together

6/7 * 7/8 will give us 3/4 or .75

1 1/8 * 1 3/7 will give us 1.61 feet

1 1/8 * 2 1/3 will give us 2.625 feet

1 3/7 * 2 1/3 will give us 3.33 or 3 1/3 ft

To find out how much paint we need, we just have to multiply 2/3 by 12

So we will get 24/3, which simplifies to 8

So we need 8 ounces of paint

Answer:

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°
