Mathematics
1 answer:
Snowcat [4.5K]3 years ago
6 0

Answer:

4

Step-by-step explanation:

If she got a 90% on her test, and the test was 40 questions long, we need to do a bit of division and multiplication.

We have to divide 40 by 100, as percentages are out of 100.

So now we have 0.4.

Now we multiply this by 90.

36. She got 36 answers correct out of 40, which means she got four wrong.

Let g(x) = 4x - 20 and h(x) = -1/2x + k. For what value of k is the zero of h(x) equivalent to the zero of g(x)
uranmaximum [27]

Answer:

Step-by-step explanation:

The zero of a function is also known as the x-intercept of a function. The x-intercept of a function exists where y = 0. So we will begin by setting each of those lines = 0:

4x - 20 = 0     and     -1/2x + k = 0 and then solve each for x:

4x = 20 so

x = 5 and

-1/2x = -k and

1/2x = k so

x = 2k. Now we set the 2 x expressions equal to each other and solve for k:

5 = 2k so

k = 5/2

A pipe is leaking at 1.5 cups per day. How many gallons per week is the pipe leaking?
neonofarm [45]
1.5 cups per day...7 days per week....1.5 * 7 = 10.5 cups per week
16 cups = 1 gallon

16/1 = 10.5/x....16 cups to 1 gal = 10.5 cups to x gal
cross multiply
(16)(x) = (1)(10.5)
16x = 10.5
x = 10.5/16
x = 0.65625 rounds to 0.66 gallons per week
