how many 1/2 cups to make 3/4 of a cup?

Answers

Fill a cup with the thing you want to measure. Pour or take out half of it into another cup(this is 1/2 cup,). Now from either of the cups take out half of the thing you are measuring(it is 1/4 cup) . Add this one fourth quantity to half of the quantity now the final quantity in the cup is 3/4( 1/2 +1/4).

We are required 1.5 half cups to form the required fraction of a cup.

What is a fraction?

The upper part of a fraction is numerator and the lower part is denominator.

How to find the fraction?

We are told to make 3/4 of a cup from1/2 of cup so let the number of times we need half of a cup be x

So

1/2 * x=3/4

x=3/2 which means 1.5

So we need 1.5 times the half cup to make 3/4 of a cup.

You invest $1,900 at 4% and it's compounded semi-annually (twice a year) for 3 years. How much will your $1,900 be worth in 3 years?

Answers

Answer:

FV= $2,139.71

Step-by-step explanation:

Giving the following information:

You invest $1,900 at 4% and it's compounded semi-annually (twice a year) for 3 years.

First, we need to calculate the semiannual interest rate:

Semmi-annual interest rate= 0.04 / 2= 0.02

To calculate the future value, we need to use the following formula:

FV= PV*(1 + i)^n

PV= $1,900

i= 0.02

n= 2*3= 6 semesters

FV= 1,900*(1.02^6)

FV= $2,139.71

Answers

Answer:

All three are similar!

Step-by-step explanation:

If you get that right, follow Sammy Revv on Spotify!

Answer:

The three of them are similar.

Step-by-step explanation:

1- Triangle A and Triangle B have two same angles, 37° and 47°, which means the two angles are congruent. According to the Angle Angle Theorem (AA), in two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar.

2- First, place both triangles correctly. When you do it, you'll notice that 24≅12, 32≅16, and 9≅4.5:

24/12 = 2 ✓ 32/16 = 2 ✓ 9/4.5 = 2 ✓

According to Side-Side-Side Theorem (SSS), if the measures of corresponding sides are known, then their proportionality can be calculated. If all three pairs are in proportion, then the triangles are similar.

3- Here, the triangle shows in each one two different angles, sharing only one which is 55°. To know if they are congruent, you can add the two different angles that show both triangles, 72° and 53°, with the 55°. If it gives 180, it means the can be congruent:

55°+72°+53 = 180° ✓

9. Find DP
please help!!!!!!

Answers

Answer:

DP = 15.

Step-by-step explanation:

I am assuming that DP EP and FP are peroemdicular bisectors of the sides of ABC.

D is the midpoint of AB so

2x + 14 = 8x - 52

14+52 = 8x - 2x

6x = 66

x = 11.

So side AD = 2(11) + 14 = 36.

Now PC = PA = 39.

So by pythagoras:

DP^2 = AP^2 - AD^2

= 39^2-36^2 = 225

DP = sqrt 225

= 15.

The length of a rectangular garden is four times its width (w), plus 3 feet. Which expression represents the garden's length in feet?

Answers

Answer: 4w + 3

Step-by-step explanation:

Since the width is represented by w.

The expression for the length of the rectangular garden which is four times its width (w), plus 3 feet will be:

= (4 × w) + 3

= 4w + 3

For example, if the width is 5feet, the length will be:

= 4w + 3

= 4(5) + 3

= 20 + 3

= 23 feet.
