A softball player has had 8 base hits out of 25 at bats for a current batting average of 8/25 = .320. How many consecutive base hits does she need if she wants to raise her batting average to .400? Explain or show your reasoning.
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.

Answer:
D. 310.86 L
Step-by-step explanation:
[tex]\textsf{Volume of a cylinder}=\pi r^2h[/tex]
where:
[tex]r[/tex] is the radius[tex]h[/tex] is the heightGiven:
r = 0.3 mh = 1.1 m[tex]\pi[/tex] = 3.14[tex]\implies \sf \textsf{Volume of the tank}=(3.14)(0.3)^2(1.1)=0.31086\:m^3[/tex]
[tex]\sf 1\:liter = 1000\:cm^3[/tex]
To convert cubic cm to cubic meters, divide by 1,000,000:
[tex]\implies \sf 1\:liter =\dfrac{1000}{1,000,000} = 0.001\:m^3[/tex]

One company makes inflatable swimming pools that come in four sizes of rectangular prisms.
The length of each pool is twice the width and twice the depth.
The depth of each pool is a whole number from 3 to 6 feet.
If the pools are filled all the way to the top, what is the volume of each pool?
Answer:
Pool 1: 2(3)*3*3= 54 ft^3
pool 2: 2(4)*4*4= 128 ft^3
Pool 3: 2(5)*5*5= 250 ft^3
pool 4: 2(6)*6*6= 432 ft^3
Step-by-step explanation:
length can be modeled by twice the width or twice the depth which means that deapth=width,
both the width and the depth are equal, hence
L= 2x
W=X
x=3,4,5,6 (which are values for depth as well as width)
susbtitute values:
Pool 1: 2(3)*3*3= 54 ft^3
pool 2: 2(4)*4*4= 128 ft^3
Pool 3: 2(5)*5*5= 250 ft^3
pool 4: 2(6)*6*6= 432 ft^3

What is the factored form of the function? what are the zeros of the quadratic function?
Answer:
The factored form of the equation is f(x) = (x - 2)(x + 10), which makes the zeros of the function x = -10 and x = 2.
In order to factor a quadratic like this, you must find factors of the constant (in this case -20). The pairs of factors are listed below.
1 and -20
-1 and 20
2 and -10
-2 and 10
4 and -5
-4 and 5
Now we must pick out the pair that add to the coefficient of x.
1 and -20
-1 and 20
2 and -10
-2 and 10
4 and -5
-4 and 5
Once you've picked out those numbers, you can place each in a parenthesis with x.
f(x) = (x - 2)(x + 10)
Then to find the zeros to the equation, set each parenthesis equal to 0 and solve.
x - 2 = 0
x = 2
x + 10 = 0
x = -10

The area of a rectangle is 46.56 mm2.
If the width is 9.7 mm, find the length.
Answer:
The length is 4.8 mm
Step-by-step explanation:
The area of a rectangle is calculated by multiplying the length times the width. So:
46.56 = l * w
46.56 = l * 9.7
To find the length, we must get "l" alone. To do this, we must divide both sides by 9.7.
46.56/9.7 = 4.8
4.8 = l
The length is 4.8
Shaunta is developing a recursive formula to represent an arithmetic sequence in which 5 is added to each term to determine each successive term. which formula could represent her sequence? f(n 1) = f(n) 5 f(n 1) = f(n 5) f(n 1) = 5f(n) f(n 1) = f(5n)
Answer:
f(n+1) = f(n)+5
Step-by-step explanation:
So lets say
f(1)=5
f(2)=10
1+1=2 so
f(2)=f(1+1)
therefor
f(n+1)=f(n)+5 since the difference of the functions is 5
the answer is A f(n+1)=f(n)+5
we know that
An arithmetic sequence is a sequence of numbers which increases or decreases by a constant amount each term
In this problem
the sequence of numbers increase by a constant amount equal to
5
each term
so
f(2)=f(1)+5
f(3)=f(2)+5
f(4)=f(3)+5
.
.
f(n+1) = f (n) + 5
therefore
the answer is the option

Slope intercept form of x intercept=3 y intercept=-5
Answer:
[tex]y = \frac{5}{3} x - 5[/tex]
Step-by-step explanation:
To write an equation in the slope-intercept form, we need the slope (which can also be calculated) and at least a coordinate.
What is slope-intercept form?
y= mx +c, where m is the slope and c is the y-interceptWhen the coefficient of y is 1, and all the other terms are on the right-hand side of the equationx- intercept occurs at y= 0 while y-intercept occurs at x= 0. With this information, let's write out the two coordinates given.
(3, 0) and (0, -5)With two coordinates, we can calculate the slope using the equation below.
[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
[tex]slope = \frac{ - 5 - 0}{0 - 3} [/tex]
[tex]slope = \frac{ - 5}{ - 3} [/tex]
[tex]slope = \frac{5}{3} [/tex]
Substitute the value of the slope into m in the equation.
[tex]y = \frac{5}{3} x + c[/tex]
Given that the y-intercept is -5, c= -5.
[tex]y = \frac{5}{3} x - 5[/tex]

Choose one answer: A: 13+t=17
B:13t=17
Find the value of t that makes the equation true
Answer:
a: 13 + t = 17
Step-by-step explanation:
the top is equal to the bottom
the top is 13 and t together but you are not multiplying
thus the answer is 13 + t = 17
Answer:
A, 13+t=17
Step-by-step explanation:
Since you are trying to find the missing part of the diagram and both rows add up to 17, the answer would be A. This is the case because you aren't multiplying 13 over and over to get 17, rather instead you are adding a number to get 17.

If f (x) = startroot one-half x minus 10 endroot 3, which inequality can be used to find the domain of f(x)? startroot one-half x endroot greater-than-or-equal-to 0 one-half x greater-than-or-equal-to 0 one-half x minus 10 greater-than-or-equal-to 0 startroot one-half x minus 10 endroot 3 greater-than-or-equal-to 0
A function assigns values. The inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The domain of a function is a set of values for which the equation is satisfied. Since the function has under root values, the value which is under the root should be non-negative so that it does not give a complex number, therefore,
The inequality [tex]\sqrt{\dfrac12x^2-10}\geq 0[/tex]satisfied to find the domain of the function f(x).
Also, we can write that 0.5x²-10≥0 for the value to be positive.
Hence, the inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.
