You received a 85, 88, and a 94 on your last three math exams. What grade would you need on your next exam to have an average of 90? (Show all work on your scratch paper and make sure you set up an equation)
You would need to get a ??????
to have an average of 90%.
Answers
Answer: 93
suppose: the grade we need on the next exam is x (x > 0)
to have an average of 90, we have the equation:
[tex]\frac{85+88+94+x}{4}=90\\\\<=>267+x=360\\\\<=>x=360-267\\\\<=>x=93[/tex]
so the grade we need on the next exam is 93
Step-by-step explanation:
[tex]suppose: the grade we need on the next exam is x (x > 0)
to have an average of 90, we have the equation:
\begin{gathered}\frac{85+88+94+x}{4}=90\\\\ < = > 267+x=360\\\\ < = > x=360-267\\\\ < = > x=93\end{gathered}485+88+94+x=90<=>267+x=360<=>x=360−267<=>x=93
so the grade we need on the next exam

If y = kx, and x = 3 and y = 15, calculate k.
Answers
Answer:
k = 5
Step-by-step explanation:
Since the equation is y = kx and x equals 3 while y equals 15, in order to solve this equation we are going to have to substitute the variables with their answers:
x = 3
y = 15
15 = 3k
Now we divide 3 from both 3x and 15 to segregate the variable x:
15/3 = 3k/3
5 = k
Now to check our work we are going to substitute 5 for the variable k, 3 for the variable x and 15 for the variable y.
y = kx
15= (5)(3)
15 = 15
Tada, I hope this helps you!
Answer:
k=5
Step-by-step explanation:
y=kx Also meaning y = k times x
x=3 y=15
y divided by x = 15 divided by 3 = 5
k=5
Lets Check Our Work
y=kx
15=?3
? times 3 is 15 = 5
solve for x thank you

The lateral surface area of the triangular prism is
Explanation:
The side lengths of the base of the triangular prism are 5 meters, 8 meters, and 10 meters.
It is given that the height of the prism is 16.5 meters.
To determine the lateral surface area of the prism, let us use the formula
LSA = (a + b + c)h
where a, b,c are the side lengths of the base of the triangular prism and h is the height of the prism.
Here: a = 5, b = 10,c = 8 and: h = 16.5
Substituting these values in the formula, we have,
LSA = (5 + 10 + 8) 16.5
Simplifying, we get,
LSA = (23) 16.5
Multiplying, we get,
LSA = 379.5
Thus, the lateral surface area of the triangular prism is,
379.5sq. units

While taking a ride in a hot-air-balloon in Napa Valley, Francisco wonders how high he is. To find
out, he chooses a landmark on the ground that is to the east of the balloon and measures the angle of
depression to be 54°. A few minutes later, after the balloon floats horizontally 100 feet east, closer to the
landmark, the angle of depression to the same landmark is determined to be 61°. Determine the height h
of the balloon. Round your answer to the nearest tenth.
a) Find the measures of ∠1, ∠2, ∠3 and ∠4:

Which statement best describes the zeros of the function h(x) = (x + 9)(x2 - 10x+ 25)?
ОА.
The function has three complex zeros.
OB. The function has three distinct real zeros.
OC.
The function has one real zero and two complex zeros.
OD.
The function has two distinct real zeros.
Answers
Step-by-step explanation:
h(x) = (x + 9)(x² - 10x + 25) = (x + 9)(x - 5)²
When h(x) = 0, (x + 9) = 0 or (x - 5)² = 0.
=> x = -9 or x = 5.
Hence there are 2 distinct real roots of h(x).
