A photo that measure 5 inches in length by 7 inches in width is enlarged to 7.5 inches in length. What is the width?

galina1969 [7]

Answer:

10.5

Step-by-step explanation:

You can use ratios to solve this problem.

The original dimensions of the photo is

5 in. by 7 in.

This can be written as:

5:7

And the next is 7.5:?

Then you can use ratios to solve this.

5:7=

7.5:?

5*1.5=7.5 so you can multiply the other side by the same thing. 7*1.5=10.5

The width is 10.5 inches.

Let A = {1, 2, 3, 4, 5} and B = {2, 4}. What is A ∩ B?

tatyana61 [14]

Answer:

A ∩ B = {2, 4}

Step-by-step explanation:

Definition: The intersection A ∩ B of two sets A and B is the set that contains all elements of A that also belong to B.

For example:

If x∈A and x∈B

then;

x∈ A ∩ B

Given the sets:

A = {1, 2, 3, 4, 5} and B = {2, 4}

We have to find A ∩ B.

By definition we have;

A ∩ B = {2, 4}

Therefore, the value of A ∩ B is, {2, 4}

Answer

15% of 30

 $30 \times 15\% \\ 30 \times \frac{15}{100} \\ = 4.5$ 

30% of 45

 $45 \times 30\% \\ 45 \times \frac{30}{100} \\ = 13.5$ 

60% of 7

 $7 \times 60\% \\ 7 \times \frac{60}{100} \\ = 4.2$ 

23% of 20

 $20 \times 23\% \\ 20 \times \frac{23}{100} \\ = 4.6$ 

Hope this helps you:-)

17. Classify Each Angle Pair then find the value of X

IRISSAK [1]

Given -

If l || m, m∠1 = (13x + 24)°, and m∠2 = (5x-6)°,

To find -

m∠2.

Concept -

Whenever two parallel lines are cut by a transversal, an interesting relationship exists between the two interior angles on the same side of the transversal. These two interior angles are supplementary angles. Hence, according to the figure l and m are two parallel lines and t is the transversal intersecting them then ∠1 + ∠2 = 180°.

Solution -

$\rightarrow\sf{(13x+24)^{ \circ}+(5x-6)^{ \circ}=180^{ \circ}}$
