Using proportions, it is found that she needs 4 consecutive hits to raise her batting average to .400.
What is a proportion?A proportion is a fraction of a total amount.
Hence, the batting average is given by the number of hits divided by the number of at-bats.
If she gets x consecutive hits, she will have 8 + x hits in 25 + x at-bats, for an average of 0.400, hence:
[tex]0.4 = \frac{8 + x}{25 + x}[/tex]
8 + x = 10 + 0.4x
0.6x = 2
x = 3.33
Rounding up, she needs 4 consecutive hits to raise her batting average to .400.

The local amusement park is a popular fleld trip destination. This year the senior class at the High
School planned their senior class trip there. The school had to take 24 total vehides between vans
Vand buses. There are 752 total students in the senior class. Each van holds 8 students and each
bus can hold 43 students. How many vans and buses did they have to take?
Answer:
8 vans16 busesStep-by-step explanation:
The given relations can be written as two equations in two unknowns. These can be solved by any of the ususal methods.
__
SetupLet v and b represent the numbers of vans and buses used, respectively.
v + b = 24 . . . . . 24 vehicles were taken
8v +43b = 752 . . . . 752 students were transported
__
SolutionPerhaps the easiest solution is that afforded by a graphing calculator. It shows the solution to be ...
v = 8 . . . . vans required
b = 16 . . . . buses required
__
You can eliminate the v variable by subtracting 8 times the first equation from the second.
(8v +43b) -8(v +b) = (752) -8(24)
35b = 560 . . . . . simplify
b = 16 . . . . . . divide by 35
v = 24 -16 = 8 . . . . . find v from the first equation
They had to take 8 vans and 16 buses.
y=(1+2z+3z^3)(5z+8z^2-Z^3)
Answer:
Step-by-step explanation:
multiplying the first bracket with the second (step by step)
= 1( 5z + 8z^2 - z^3) +2z ( 5z + 8^2 - z^3 )+3z^3 (5z + 8^2- z^3)
= 5z + 8z^2 - z^3 + 10z^2 + 16z^3 - 2z^4 + 15z^4 + 24z^5 -3z^6
=5z + 16z^2 + 15z^3 + 17z^4 + 24z^5 -3z^6

Find the volume of the cone.
Use 3.14 for π. Round your answer to the nearest tenth if needed. Do not enter units.
Step-by-step explanation:
Volume of a cone = 1/3 x π x r^2 x h
= 1/3 x 3.14 x (8)^2 x (18)
= 1/3 x 3.14 x 64 x 18
= 1/3 x 3.14 x 1,152
= 1/3 x 3.14 x 1,152
= 1,205.76

A parallelogram has an area of 37 square feet. If the height of the parallelogram is 4 feet, how many feet is the base?
Answer:The base of the given parallelogram is
Step-by-step explanation:Area of a parallelogram is defined as the product of its base and height respectively. Mathematically;
→ Area of parallelogram = base * height
By substituting the given values in the formula, we get the following results:
→ 37 = base * 4
→ base = 37/4
→ base = 9.25
Hence, the base of the given parallelogram is 9.25 feet.
Additional information:Let's know something more about a parallelogram.

Find the sum of the first 6 terms of the following sequence. Round to the nearest
hundredth if necessary.
324,
54,
9….
Answer:
388.79 (nearest hundredth)
Step-by-step explanation:
Given sequence: 324, 54, 9, ...
Therefore:
[tex]a_1=324[/tex]
[tex]r=\textsf{common ratio}=\dfrac{54}{324}=\dfrac16[/tex]
Sum of a finite geometric series:
[tex]S_n=\dfrac{a_1-a_1r^n}{1-r}[/tex]
Sum of the first 6 terms → n= 6:
[tex]\begin{aligned}S_6 & =\dfrac{324-324(\frac16)^6}{1-\frac16}\\ & =\dfrac{324-\frac{1}{144}}{1-\frac16}\\ & =\dfrac{9331}{24}\\ & = 388.79\:\textsf{(nearest hundredth)}\end{aligned}[/tex]
So
[tex]\\ \rm\Rrightarrow S_n=\dfrac{a-ar^n}{1-r}[/tex]
[tex]\\ \rm\Rrightarrow S_6=\dfrac{324-324(1/6)^6}{1-1/6}[/tex]
[tex]\\ \rm\Rrightarrow S_6=\dfrac{324-\dfrac{1}{12^2}}{\dfrac{5}{6}}[/tex]
[tex]\\ \rm\Rrightarrow S_6=\dfrac{9331}{24}=388.79[/tex]
