Select each pair of equivalent numbers. PLS HELP DUE TMR AND I DONT HOW TO SOLVE IT, PLS SHOW HOW U SET IT UP

Answers

The pairs that are equivalent to each other are 40/1000 and 40%, 6/5 and 120%, 1/8 and 12.5% . They are the correct answers because if we divide for example 6/5 , we would get 1.2 and to turn a decimal into a percent we have to move the decimal point 2 times to the right meaning that the percentage would be 120% and you just do that for all!

At the dealership where she works, Denise fulfilled 1/2 of her quarterly sales goal in January and another 5/12 of her sales goal in February. What fraction of her quarterly sales goal had Denise reached by the end of February?

Answers

Answer:

She has fulfilled about 91.6666 repeating

Step-by-step explanation:

If half of her sales were fulfilled in January, then that is 50% or 0.5. Then if you take 5/12 then it = 0.41666666, add the two decimals together and you have 0.916666 repeating. If you want to turn that into a fraction it would be 9/10 by rounding down due to the decimal.

Answer:

the answer will probably be around 1 / 12

Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in.

What is the area of the curved surface of the trash can she will need to decorate?


A trash can with radius 4 inches and height 12 inches.

Answers

12 in =30 cm

4 in = 10 cm

area of 1 circle= 3.14×10×10= 314 cm²

area of 2 circle= 314×2= 628 cm²

if u unfold the trash can the biggest surface(not the circle) will become a rectangle with two circles(628 cm²)

length of rectangle = circle circumference

= 2×3.14×10

=62.8 cm

area of rectangle= 62.8 × 30 = 1884 cm²

total area= 1884 + 628 = 2512 cm²

Find the quotient. Express your answer as a simplified fraction. 3/10 divided by 3.8

Answers

Answer:

4/5



Step-by-step explanation:

3/10÷3/8

=(3×8)/(10×3)

=24/30

Simplifying 24/30, the answer is

=4/5

The value of the quotient of ''3/10 divided by 3.8'' as a simplified fraction would be 3/38.

Given that;

The expression is,

3/10 divided by 3.8

Now it can be divided as,

3/10 divided by 3.8

3/10 ÷ 3.8

3/10 × 1/3.8

3/38

Therefore, the value of the quotient as a simplified fraction would be 3/38.

Answers

Answer:

y=3/4x

Step-by-step explanation:

From the origin (0,0) count the rise to the next point (3) and then the run (4) leaving you with 3/4 as your slope.

well, we see that it is a linear function.

so, we should make an equation that follows:


y = mx + b


b = y intercept, which is 0 because it connects at the origin.


m is the slope, which is rise/run.

we find a point at ( 0.7 , 0.5 ).

the rise is 0.5, and the run is 0.7, so we do

0.5/0.7

and we get 0.714285714285714, which we can round to 0.7143 for the m.

we have everything we need.


so,


y=0.7143x


(the b is 0, so we don’t have anything else to add).


hope this helped!

Answers

it’s a linear function so,

y = mx+b

b is 0.

m is rise/run, which is 6/3, which is 2.

so

y=2x


hope this helps!

Answer:

y = 2x

Step-by-step explanation:

the equation of proportional relationships are in the form y = mx, where m is the slope.

this means you need to solve the slope.

to find the slope, find 2 random points and do change in y divided by change in x.

for example, (3, 6) and (0, 0)

this would be (6 - 0)/(3 - 0) = 2

this means m = 2

so the equation is y = 2x
