willa can type 900 words in a quarter of an hour. how many words per minute can willa type?
Answer:
Willa can type 60 words per minute
Step-by-step explanation:
60 minutes = 1 hour
1/4 hour = 1/4 × 60 minutes
= 60/4 minutes
= 15 minutes
Quarter of an hour= 15 minutes
Willa can type 900 words in 15 minutes
how many words per minute can willa type?
Words per minute= Total words in 15 minutes / 15 minutes
= 900 / 15
= 60 words per minute
Willa can type 60 words per minute

Given f(x)
=
4x + 1
3
solve for F-1(3). (5 points)
Answer:
Step-by-step explanation:
First we need to find inverse function of f(x) which is written in a form of (f(x))^(-1)
That means that we are actually looking for function f(y) and we need to solve this equation for "y"
y=(4x + 1)/3
3y = 4x + 1
4x = 3y - 1
x = (3y - 1) / 4
f(y) = (3y - 1)/4
Now we simply put the value of 3 instead of y and find the answer:
f(y=3) = (3*3-1)/4 = 2
Answer is 2
how many pieces each of length 9/4metre can be cut from a rope of length 40 metre 50 cm
Answer:
18 pieces
Step-by-step explanation:
This is a division problem.
1 m = 100 cm
To convert from cm to m we divide the length in cm by 100.
40 m + 50 cm = 40 m + 50/100 m = 40.5 m
The rope is 40.5 m long.
9/4 m = 2.25 m
Each piece is 2.25 m long.
[tex] \dfrac{40.5~m}{2.25~m} = 18 [/tex]
Answer: 18 pieces

A. It's a straight line so the angle is 180. U subtract 50 from. 180 and u get 130
B. It 50 because it's vertically opposite angle to angle AEC
Answer:
a. the angle measure is 130°
b. the angle measure is 50°
Step-by-step explanation:
a. you have to subtract 180°- 50° to get 130°
b.angle AEC is congruent to angle DEB so they are both 50°

This is the same as:
[tex]=\pm\sqrt{66\cdot-1}[/tex]
Separate:
[tex]=\pm\sqrt{66}\cdot\sqrt{-1}[/tex]
Replace the second term with i:
[tex]=\pm i\sqrt{66}[/tex]

a right triangle has side lengths 8 15 and 17 as shown below use these lengths to find tan B sin B and cosine B
Answer:
sin(B) = [tex]\frac{15}{17}[/tex]
cos(B) = [tex]\frac{8}{17}[/tex]
tan(B) = [tex]\frac{15}{8}[/tex]
Step-by-step explanation:
I always find it easiest to model out the triangle: Angle B will be at the converging point of a and c.
Using SOH CAH TOA, we know that the Sin of an angle will be its opposite over hypotenuse. The opposite is 15, and the hypotenuse is 17.
So [tex]\frac{15}{17}[/tex] is the sin of B.
We also know that the cosine of B will be it's adjacent over hypotenuse. The adjacent is 8 and the hypotenuse is 17, so
[tex]\frac{8}{17}[/tex]
Lastly, we know the tangent of B will be it's opposite over adjacent. The opposite of B is 15, and it's adjacent is 8, so
[tex]\frac{15}{8}[/tex] is the tangent of B.
Hope this helped!

Mr. Jackson is ready to empty his backyard swimming pool for the winter. He knows that the time, T, required to empty the pool varies inversely as the rate, R, of pumping. Mr. Jackson's old pump could empty the pool in 55 minutes, pumping at a rate of 200 gallons per minute. This year he has a new pump which pumps at a rate of 325 gallons per minute. How long will it take to empty the pool this season? Round your answer to the nearest minute. DUE IN 2 HOURS, 15 POINTS, WILL GIVE BRAINLIEST.
Answer:
34 minutes
Step-by-step explanation:
Given that T varies inversely as R then the equation relating them is
T = [tex]\frac{k}{R}[/tex] ← k is the constant of variation
To find k use the condition
T = 55 when R = 200, that is
55 = [tex]\frac{k}{200}[/tex] ( multiply both sides by 200 )
11000 = k, thus
T = [tex]\frac{11000}{R}[/tex] ← equation of variation
When R = 325, then
T = [tex]\frac{11000}{325}[/tex] ≈ 34 minutes ( to the nearest minute )
Answer:
Option 2
Step-by-step explanation:
An inverse variation can be represented by the equation xy=k or y=kx .
If (x1,y1) and (x2,y2) are solutions of an inverse variation, then x1y1=k and x2y2=k
Substitute x1y1 for k
x1y1=x2y2 or x1x2=y2y1
The equation x1y1=x2y2 is called the product rule for inverse variations.
Let x be the time required, and y the rate of pumping.
x1 = 55min y1 = 200gal/min
x2 = Unknown y2 = 325gal/min
(55)(200) = x2(325)
11,000 = x2 (325)
11,000/325 = x2
33.84 = x2

Tammy drove 715 miles in 11 hours. at the same rate, how long would it take her to drive 845 miles?
Answer:
Step-by-step explanation:
So we have direct proportions here.
So
715=11
845=x
845*11/715
x=13
To check our work.
715/11=65
65*13=845.
Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/
So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.
Hope this helped, ask me if you have any questions.
what is f(3) for f(x)=3x+2
Answer:
f(3) = 11
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x), that is
f(3) = 3(3) + 2 = 9 + 2 = 11
Answer: f(3) = 11
Step-by-step explanation: Notice that f is a function of x.
So we want to find f(3).
We find f(3) plugging 3 in for x,
everywhere that x appears in the function.
So we have 3(3) + 2 which is 9 + 2 or 11.
So f(3) = 11.

Express 0.7 as a fraction
Answer:
7/10
Step-by-step explanation:
In 0.7 we will change the decimal to fraction. First we will write the decimal without the decimal point as the numerator. Now in the denominator, write 1 followed by one zeros as there are 1 digit in the decimal part of the decimal number. Therefore, we observe that 0.7 (decimal) is converted to 7/10

Can you explain why the answer to 12-8x=3(x+4) is x=0 ?
Answer:
12 - 0 = 12.
Step-by-step explanation:
If you substitute all x values for 0, then you get 12 - 8(0) = 3(0+4). Combine like terms and you will arrive at 12 - 0 = 3(4). Which then goes to 12 - 0 = 12. Since 0 has no value, just remove it from the equation. You are left with 12 = 12.
Answer:
it is x= 0
Step-by-step explanation:
you distribute the numbers in the parentheses first so your new equation would be 12 - 8x = 3x + 12 (basically multiply 3 by what was in the parentheses)
then cancel equal terms so 12 - 8x = 3x + 12 becomes -8x = 3x
after that move the variable and the 3 to the left while changing the sign from + to - (the + sign is implied since it's a positive number) your new equation becomes -8x - 3x = 0
next collect like terms so the numbers with the same variable meaning subtract -8x - 3x also known as -8x + -3x creating the equation -11x =0
finally divide both sides of the equation -11x = 0 by -11 creating x=0
