The diagram represents a triangle that is reduced by a scale factor of 0.4.

A rectangle has a base of 6 inches and a height of 2 inches.

What is the height of the original triangle?
0.8 inches
2.4 inches
5 inches
8 inches

Answers

Answer 1

Answer:the answer would be 8.

Step-by-step explanation:

If you look at the reduced triangle, the height is 2. Therefore you would have to multiply by 4 instead of 0.4 even if the scale factor is 0.4. The reason is, you are enlarging the triangle to find the bigger triangle. If you did 0.4 times 2 you would get 0.8. But that wouldn’t make any sense if you said that that was the height of the ENLARGED triangle.

Answer 2

Answer:

8

when solving an equation, which is the best first step to begin to simplify the equation? -2(x+3)=-10​

Answers

Answer: Following the rules of PEMDAS, you want to divide both sides of the equation by -2. This would change your equation to x+3=5. Then you move your constant to the right-hand side and change its sign. Your equation is now x=5-3. subtract 5-3 and your answer is x=2.


A triangle has side lengths of 21, 27, and 35 inches. Is it
right triangle?

Answers

Answer: No
In right triangle we have 30:60:90
and the ratios are
x: x root of 3: 2x
so, for example, if we have side of length 3 against 30 degrees, then against 60 degrees the side will be 3 root of 3, and against 90 degrees it will be 6.

A 6 ounce serving of grapefruit juice contains 171 grams of water. How many grams of water are in 20 ounces of grapefruit juice?

Please help me with this question. I have 2 minutes left to answer it.

Answers

Answer:

570 grams of water

Step-by-step explanation:

171 divided by 6 = 28.5

28.5 grams are in 1 ounce

so Multiply 28.5 by 20 to get the new amout which is 570

The amount of water present in 20 ounces of grapefruit juice will be 570 grams.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

A 6-ounce serving of grapefruit juice contains 171 grams of water.

The ratio of the amount of grapefruit and water present will remain constant.

Let 'x' be the amount of water present. Then the equation is given as,

x / 20 = 171 / 6

x = 20 · 171 / 6

x = 570 grams

The amount of water present in 20 ounces of grapefruit juice will be 570 grams.

A retail store makes k% profit on the selling price. What is the least integer value of k that will enable the store to make a profit of at least 30% of the cost of the item?

Answers

Answer:

k = 23% profit on sale price is needed to ensure 30% profit on cost price

Step-by-step explanation:

Let sale price be = s , Profit = k% of s

Let cost price be = 100 , Profit = 30% of c

Cost price (c) + profit (p)  = Sale price (s)

c + 0.3c = s

1.3c = s

Profit as a percentage of sale = (Profit / Sale) x 100

= (0.3c / 1.3c) x 100

= 23%

Which pair of vectors is orthogonal?

u = ⟨1, 5⟩ and v = ⟨–5, 1⟩
u = ⟨2, 1⟩ and v = ⟨–4, 3⟩
u = ⟨2, 3⟩ and v = ⟨3, 1⟩

Answers

Answer:

B: u = (1,5) and v = (-5,1)

Step-by-step explanation:

edge 2021

The pair of vectors which are orthogonal to each other will be u = ⟨1, 5⟩ and v = ⟨–5, 1⟩. Then the correct option is B.

What is a vector?

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

For the orthogonal vector, the dot product of two vectors will be zero.

Check first option, we have

u·v = ⟨–3, 2⟩·⟨–2, 1⟩

u·v = 6 + 2 = 8 (incorrect)

Check second option, we have

u·v = ⟨1, 5⟩·⟨–5, 1⟩

u·v = –5 + 5 = 0 (correct)

Check third option, we have

u·v = ⟨2, 1⟩·⟨–4, 3⟩

u·v = –8 + 3 = –5 (incorrect)

Check fourth option, we have

u·v = ⟨2, 3⟩·⟨3, 1⟩

u·v = 6 + 3 = 9 (incorrect)

Then the correct option is B.

In a small private liberal arts college, 40 percent of the students receive financial aid, and 30 percent of the students that receive financial aid also are first generation college students. In addition, 25 percent of the students in the college own a hybrid car. What is the probability that a randomly selected student receives financial aid and is first generation college student

Answers

Answer:

P(A∩B) = 0.12

Step-by-step explanation:

Given:

Students receive financial aid P(A) = 40% = 0.4

Students receive financial aid and first generation P(B/A) = 30% = 0.3

Find:

Probability [Selected student receives financial aid and is first generation college student] P(A∩B)

Computation:

P(A∩B) = P(A) x P(B/A)

P(A∩B) = 0.4 x 0.3

P(A∩B) = 0.12
