Answer:

$(a)=6\\(b)=1\ \frac {1}{2}\\(c)=1\ \frac {1}{2}\\d=6$

Step-by-step explanation:

(a)

3 ft long when divided into half ft each will be

3ft ÷1/2 ft

We change the ÷ to × then the second part is reciprocated hence

3ft÷1/2= 3ft×2/1=6 pieces

(b)

The question requires us to get the differences. Initially, Phil makes 3 quarts of soup but the family takes only half of the original quantity to mean Phil remains with the other half.

Therefore, half of 3 is 3×1/2=3/2= 1.5 or 1 1/2

(c)

Hiding 3 pounds of gold into two equal sections means 3 is divided by 2

3÷2=1.5 or 1 1/2

(d)

If half, 0.5 represent 3 cups then full quantity represent x

0.5=3 cups

1=x

By cross multiplication

1*3/0.5=6

After counting her weekly earnings, she bought a candy bar for $.45, a pen for 250 and her mom gave her 2.00. She had $5.05 left

horsena [70]

Answer:

She started with $6.00.

Step-by-step explanation:

1. This problem is meant to have you work backwards from the information given. Firstly, it is important to write all the expenses and earnings she had to her weekly earnings.

Starting Amount = ?

- $0.45 (candy bar)

- $2.50 (pen)

+ $.200 (mom)

End Total = $5.05

2. With this information, this next step will be much easier. With this process, you can now use inverse operations to undo the last few equations.

Firstly, $2.00 given by her mom will be subtracted from $5.05.

Secondly, with our new total of $3.05, $2.50 from purchasing the pen will be added to this amount. This leaves you with $5.55.

Lastly, the $0.45 cents she spent with the candy bar will be added to the $5.55.

This leaves the starting amount to $6.00.

3. She started with $6.00

Find the value of xxx in the isosceles triangle shown below.

Ivahew [28]

Answer:

$x=10\ units$

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The height of an isosceles triangle divide the triangle into two congruent right triangles.

Applying the Pythagorean Theorem

$(\sqrt{74})^2 =7^2+(\frac{x}{2})^2$

solve for x

$74 =49+\frac{x^2}{4}$

$\frac{x^2}{4}=74-49$

$\frac{x^2}{4}=25$

$x^2=100\\x=10\ units$
