Step-by-step explanation:

This are the options:

A. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 4 equal parts.

B. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 8 parts.

C. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 5 equal parts.

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

Amount of Fabric owned by Louisa = 4 yards

If she uses 2/5 yards to make a doll dress, to get the number of dolls that 4 yards can make we will say:

1 doll = 2/5 fabric

x doll = 4 fabrics

Cross multiply

2/5 * x = 4*1

2x/5 = 4

cross multiply

2x = 20

Divide both sides by 2:

2x/2 = 20/2

x = 10

This means that she can make 10 dolls using 4 yards of fabric.

Hence the correct option will be

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

Answer:

Original : $437.416 Rounded to Nearest Cent : 437.42

Step-by-step explanation:

Turn 30% into a decimal which is 0.3. Now multiply 0.3 by 584.

0.3 x 584 = 175.2

Now you have to subtract the answer by the original price, $584.

584 - 175.2 = 408.8

Finnaly, you have to find the sales tax of $408.8. In order to find that, you have to convert 7% into a decimal which is 0.07, then multiply it by 408.8. Then you have to add 408.8 to the following answer.(You can change a percent into a decimal by doing the number divided by 100)

0.07 x 408.8 = 28.616

408.8 + 28.62 = 437.42

Here's your answer. I know I'm late.

The cost of the kit is $437.416

A deduction from the usual cost of something, typically given for prompt or advance payment or to a special category of buyers.

Given that, Brandt is buying a new set of golf clubs for $584. If the clubs are on sale now for 30% off and sales tax is 7%, we are asked to how much will he pay in total,

The cost of golf kit will be,

= (100-30)% of 584 + 7% of (100-30)% of 584

= 70% of 584 + 7% of 70% of 584

= 408.8 + 28.616

= 437.416

Hence, the cost of the kit is $437.416

Step-by-step explanation:

Since 2 1/2 cups of sherbet are needed to make 24 cups, and we need to make 12 cups of punch, it's basically 24 divided by 2. So we need to divide 2 1/2 by 2, which would be 1 1/4 cups.

DISTANCE BETWEEN TWO POINTS

We want to firstly assume that the the three trees lies on the same line

so tress A,B and C are on the same line

Given

The direct distance between A to B= 200 ft

The direct distance between B to C= 300 ft

hence A to C= 200+300= 500ft

let us do a graphical representation for better understanding

A----B-----------C

200ft    300ft

A---------- -----C

       500ft

A to C= 500ft

Answer:

Between 100 and 500

Step-by-step explanation:

A to B is 200

And b to c is 300

A to C =500

200-300=100

Answer:

shortest side = 3 in

Explanation:

Sum the 3 sides and equate to 13, that is

x - 5 + 6 +  = 13, that is

x + 1 +  = 13 ( subtract 1 from both sides )

x +  = 12 ( multiply through by 2 to clear the fraction )

2x + x = 24

3x = 24 ( divide both sides by 3 )

x = 8

 x - 5 = 8 - 5 = 3 and  =  = 4 , then

The shortest side is x - 5 = 3 in

Answer:

Each leg in a right triangle is adjacent to one of the acute angles and opposite the other acute angle.

Keep in mind that the labels “opposite” and “adjacent” depend on which angle you are talking about. The side opposite an angle does not need to be the height of the triangle. Consider the following example:

Answer:

The percentage of students who chose art is 52 %

Step-by-step explanation:

Given;

total number of students, T = 100 students

number of students who chose mathematics, m = 22

number of students who chose history, h = 26

number of students who chose art, a = 100 - (22 + 26)

number of students who chose art, a = 52

percentage of students who chose art = (a / T ) x (100%)

= (52 / 100) x (100%)

= 52 %

Therefore, the percentage of students who chose art is 52 %

Answer:

2/5 & 1/10

Step-by-step explanation:

So, the result we are looking for is 3/2

Simplify the following:

1/5 + 7/10 + 3/5

Put 1/5 + 7/10 + 3/5 over the common denominator 10. 1/5 + 7/10 + 3/5 = 2/10 + 7/10 + (2×3)/10:

2/10 + 7/10 + (2×3)/10

2×3 = 6:

2/10 + 7/10 + 6/10

2/10 + 7/10 + 6/10 = (2 + 7 + 6)/10:

(2 + 7 + 6)/10

2 + 7 + 6 = 15:

15/10

The gcd of 15 and 10 is 5, so 15/10 = (5×3)/(5×2) = 5/5×3/2 = 3/2:

Answer: 3/2
