Answer:
A. 9.8 h
Step-by-step explanation:
1. Use the formula d = rt. Find t for r = 46.6 m/h and d = 456.68 m. Show your work.
2. Express 0.578 in words
1. d = rt
456.68 = 46.6 times t
divide both sides by 46.6 to get 9.8
So the time is 9.8
2. 0.578 is five hundred seventy-eight thousandths
Hope this helps
For the first problem all you have to do is plug in r and d in the equation and solve for t. So here is how we do that:
d=rt
546.68=46.6t
11.73=t
All we did there was divide both sides to isolate t (get t by itself).
For the second one you just need to know the places after the decimal point. The first spot is the tenths, the second is the hundredths, and the third is the thousands. So you would read 0.578 as:
Five-hundred and seventy-eight thousandths.
Substituting:
456.68 = 46.6t, so, dividing ach side by 46.6:
t = 456.68/46.6, so
t = 9.8
2. nought point five seven eight.

SOLVE THESE TWO FOR BRAINLY PLSSSS!!!!!!!!
Answer: 1) D
2) A
Step-by-step explanation: plz mark me brainliest
Answer:
1) C) 2) B)
Step-by-step explanation:
First one is just times them together get 12root(a^2b^2) = 12ab.
Second question, you use equation 1 to minus equation 2 get 2x = 6, then x = 3, then substitute it into either equation, for example the first one get -7*3 + 5y = 24, then solve for y, can get y = 9, so B) is correct answer.

The odometer in a car measures the number of miles driven by the car since it was made. During a trip, the odometer reading in Anita’s car is modeled by the function y=9500+55x, where x represents the number of hours driven during the trip and y represents the odometer reading in miles.
Part A
What is the meaning of the rate of change in this function?
The number of miles driven each hour during the trip.
The total number of miles driven at the beginning of the trip.
The total number of miles driven at the end of the trip.
The number of miles driven during the trip.
Question 2
Part B
What was the odometer reading, in miles, before Anita’s trip?
Answer:
Step-by-step explanation:
Part A
The units on 9500 must be miles. So if x is time, then 55 must be the rate at which she travels ie 55 miles per hour. So the answer must be A.
Part B
The trip began when the time was zero. Therefore x is zero. What remains is the mileage on the odometer when x = 0. The answer must be 1950.
what is the value of y?
Answer:
the answer to that is 4 hope it help
Answer:
y = 8
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4}{y}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
y = 8

Answer: 16p^8q^4r^8 The yellow one
Step-by-step explanation:
Step 1: Use Multiplication Distributive Property: (xy)^a = x^a y^a. So 4^2p^2(q^3)(r^4)^2
Step 2: Simplify 4^2 to 16. So 16p^2(q^3)^2(r^4)^2
Step 3: Use Power Rule: (x^a)^b=x^ab. So 16p^2q^6(r^4)^2
Step 4: Use Power Rule: (x^a)^b=x^ab. So the answer is 16p^2q^6r^8. The yellow one

Answer:
Step-by-step explanation:
Sin A = [tex]\frac{opposite side}{hypotenuse}=\frac{5}{13}\\\\[/tex]
Cos A = [tex]\frac{Adjacent side}{hypotenuse}=\frac{12}{13}[/tex]
Tan A = [tex]\frac{opposite side}{adjacent side}=\frac{5}{12}[/tex]
A = tan⁻¹ (5/12) = 22.61°
Answer:
Step-by-step explanation:
a) Sin A = opposite/hypothenuse
Sin A = 5/13 ≈ 0.3846..
b) Cos A = adjacent/hypothenus
Cos A = 12/13 ≈ 0.9230..
c) Tan A = opposite/adjacent
Tan A = 5/12 ≈ 0.4166..
d) we will use the inverse Sine function
< A = sin^-1(5/13)
< A = sin^-1(0.3846) ≈ 22.62°
P.S. You can use any of the three inverse functions to find the angle: sin^-1 | cos^-1 | tan^-1

Answer:
6ft
Step-by-step explanation:
On a certain hot summer's day, 218 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $349.75.
How many children and how many adults swam at the public pool that day?
Answer:
We call x the number of children and y the number of adults
We have system of equations
x + y = 218 (1)
1.25x + 2y = 349.75 (2)
(1) => x = 218 - y. Replace x in (2) 1.25 (218-y) + 2y = 349.75
=> y = 103 replace y in (1) x = 218-103 = 115
Children and how many adults swam at the public pool that day is : 115 and 103

Find CD
This question is represented with the attached triangle
To solve CD, we make use of tan formula.
[tex]tan(70) = \frac{DE}{CD}[/tex]
Substitute 12 for DE
[tex]tan(70) = \frac{12}{CD}[/tex]
Make CD the subject

A radio disc jockey has 8 songs on this upcoming hour's playlist: 2 are rock songs, 4 are reggae songs, and 2 are country songs. The disc jockey randomly chooses the first song to play, and then she randomly chooses the second song from the remaining ones. What is the probability that both songs are reggae songs? Write your answer as a fraction in simplest form.
Answer:
[tex] \displaystyle \frac{1}{28} [/tex]
Step-by-step explanation:
we are given 8 songs
2 are rock. 4 are reggae, 2 are country
we want to figure out the probability of getting both reggae songs
notice that, they aren't replacing thus it's an independent probability
recall that,
[tex] \displaystyle \rm P(A \: \text{and} \: B) = P(A) \times P(B \mid A)[/tex]
P(A) represents the chance of getting our subject first time and P(B|A) represents the chance of getting the same subject second time
let's figure out P(A)
we have 2 reggae songs
and total 8 songs
therefore
[tex] \displaystyle\rm P(A) = \frac{2}{8} = \frac{1}{4} [/tex]
let's figure out P(B|A)
since we took a reggae song before now we have only a reggae song
and total 8-1=7
therefore
[tex] \displaystyle \rm P(B\mid A) = \frac{1}{7} [/tex]
Altogether
[tex] \displaystyle \rm P(A \: \text{and} \: B) = \frac{1}{4} \times \frac{1}{7} [/tex]
simplify multiplication:
[tex] \displaystyle \rm P(A \: \text{and} \: B) = \frac{1}{28} [/tex]
And we are done!

The volume of a mini-basketball is approximately 4846.59 cubic centimeters. What is the approximate radius of a mini-basketball?
A
10.5 cm
B
11.5 cm
C
21 cm
D
23 cm
Answer:
