Grade 6 - End of term assessment

sertanlavr [38]

Answer:

The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Step-by-step explanation:

Given

Total length of one roll of ribbon = 9 feet

As the pieces have to be cut into inches, we will convert the measurement in feet to inches

As there are 12 inches in one feet, 9 feet will be equal to:

9*12 = 108 inches

Now first of all, we have to see how many 15 inches pieces can be cut from one role

So,

$=\frac{Length\ of\ roll}{Length\ of\ piece}\\=\frac{108}{15}\\=7.2$

So the seamstress can cut 7 15-inch long pieces from a roll.

Now given that he has to cut from 5 rolls, the total number of 15-inch pieces will be:

$= 5 * 7 =35$

Hence,

The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Marsha is buying a new cell phone. She has a 45% off coupon from the store. She pays $275 for the cell phone. What is the price

jekas [21]

Answer:

The price of the cell phone without the coupon= $500

Step-by-step explanation:

Step 1: Express discounted amount

The discounted amount can be expressed as a function of the original cost of the phone as follows;

D=r×A

where;

D=discounted amount

r=coupon rate

A=original price of the cell phone before the coupon

In our case;

r=45%=45/100=0.45

A=a

replacing;

Discounted amount=(0.45×a)=0.45 a

Step 2: Amount she pays up

Amount she pays=Original cost of cell phone-discounted amount

where;

Amount she pays= $275

original cost of cell phone=a

discounted amount=0.45 a

replacing;

$275=a-0.45 a

0.55 a=275

a=275/0.55

a=500

The price of the cell phone without the coupon= $500

Could someone answer this pls thank u

Given:

The area model.

The area of the shape is 82 square units.

To find:

The correct equation for the given situation.

Solution:

We know that, area of a rectangle is

$Area=Length \times Width$

The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is

$A_1=(x)\times (3x)=3x^2$

$A_2=(x)\times (4)=4x$

$A_3=(3)\times (3x)=9x$

Now, the total area is equation to 82 square units.

$A_1+A_2+A_3=82$

$3x^2+4x+9x=82$

$3x^2+13x=82$

Since the required equation is $3x^2+13x=82$ , therefore, the correct option is C.
