Answers

Answer:

Step-by-step explanation:

Here's what's going on: some person buying their furniture sees this sofa and it's $1200. That person sees theres a 1/3 off sale! They're happy and buy their sofa with a 20% off discount they got.

Now we have to find out if they should use the 20% off discount before or after adding the 1/3 off sale.

The answer is, they're both the same.

Say they add the 1/3 off sale discount and then use their 20% off discount. Find the 1/3 off sale: 1200 divided by 3 (because fractions are division problems) = 400. 20% of 400: 400 x 0.2 = 80. It's not just 80, because it's not an "only pay 20%" discount. 400 - 80 = 320. They'd pay $320 with this method.

This shows that using the 20% discount after the 1/3 off sale the customer spends $320.

Now let's calculate what happens if they use the discount after the 1/3 off sale. 20% of 1200: 1200 x 0.2 = 240. 1200 - 240 = 960. Now adding the 1/3 off sale: 960 divided by 3 = 320. They'd also pay $320 with this method.

If it's a short answer, you could just write something like, "No, both methods end up with the sales associate paying $320."

Hope this helps!

Find the area of the region bounded by the y-axis, x-axis and the line y=-2x+4.

Answers

Answer:2

Step-by-step explanation:y = 0 : 0 = -2x + 4 → x = -2 is the x-intercept. Similarly, when the line crosses the y-axis, the x-coordinate at this point will be zero and substituting x = 0 into the equation will give us the y-intercept. x = 0 : y = 0 + 4 → y = 4 is the y-intercept.

Suppose a cheetah could travel 1.5 hours a top speed covering 111.9 miles how far could the cheetah travel in 1 hour

Answers

1 hour = 74.6
u get that by doing :
37.3(2) which equals 74.6

The number of miles that the cheetah will travel in 1 hour based on the ratio will be 74.6 miles.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

A cheetah could travel for 1.5 hours at a top speed covering 111.9 miles.

The ratio of the number of miles to time = 111.9/1.5

With the same ratio, the number of miles x in 1 hour will be as,

x/1 = 111.9/1.5

x = 74.6 miles.

Hence "The number of miles that the cheetah will travel in 1 hour based on the ratio will be 74.6 miles:".

Solve the equation.
1/10 (x + 34) = −2(4 − x)
x = _____

HELPPP PLZZ DUEE TODAYY

Answers

Answer:

−0.383

Step-by-step explanation:

Let's solve your equation step-by-step.

1/10 (x+34)=(−2(4−x))(x)

Step 1: Simplify both sides of the equation.

1/10 x+ 17/5 =2x2−8x

Step 2: Subtract 2x^2-8x from both sides.

1/10 x+ 17/5 −(2x2−8x)=2x2−8x−(2x2−8x)

−2x2+ 81/10 x+17/5 =0

For this equation: a=-2, b=8.1, c=3.4

−2x2+8.1x+3.4=0

Step 3: Use quadratic formula with a=-2, b=8.1, c=3.4.

−b±√b2−4ac

−(8.1)±√(8.1)2−4(−2)(3.4)
