Answer: Darren got 75% of the questions correct.
Step-by-step explanation:
To find the percentage of questions Darren got correct, we can divide the questions he got correct by the total number of questions.
42 ÷ 56 = 0.75
0.75 X 100 = 75
So, Darren got 75% of the questions correct.
Dr. W Sweet Rides Car Rental charges a flat fee of $24 and an additional $0.35 for every mile the car is driven. Which function models the total cost, C(x), of renting a car for x miles?
If you drive 40 miles, how much can you expect to pay?
Step-by-step explanation:
this is a strange rental company charging no daily fees.
but ok.
so, we have a fixed part of the cost : $24
we have to pay that no matter how many miles we drive. even for 0 miles, just to get the keys to the car.
and then we pay $0.35 for every mile driven.
that makes our function
C(x) = 0.35x + 24
and if we drive 40 miles, that makes x = 40.
C(24) = 0.35×40 + 24 = 14 + 24 = $38
it would cost us $38.
Three numbers have an average of 15. If two of the numbers are 10 and 12, then what is the other number?
Answer with supporting work:
Answer:
Step-by-step explanation:
(12+10+x)/3=15
15*3=12+10+x
45-12-20=x
X=23
F(x) = the integral from 0 to x cos(t^2)dt. Use your calculator to find F’(1)
By the fundamental theorem of calculus,
[tex]\displaystyle F(x) = \int_0^x \cos(t^2) \, dt \implies F'(x) = \cos(x^2)[/tex]
and so F'(1) = cos(1).

An electrician cut 3 5/8 yards of wire into six equal sections. After cutting, how long was each piece?
Answer:
29/48
Step-by-step explanation:
3 5/8 Divided By 6= 29/48
Dividing fractions is simple if you know what to do, and how to multiply.
Here's how:
-----------------------------
1. convert any whole number or mixed number into a fraction.
6 = 6/1.
Whole number x denominator + numerator = 29/8
(3) (8) (5) (answer/original denominator)
-----------------------------
2. Keep, Change, Flip (KCF)
29 1
__ x __
8 6
With KCF, we keep the first fraction, change the division to multiplication, and flip the second fraction.
---------------------------------------
3. Multiply numerators and denominators
29 x 1 = 29
__
8 x 6 = 48
29/48 is in it's simplest form.
Hence, your answer.
Each wired piece was 29/48 of a yard.P.S - Please let me know if i made any mistakes.A board isThree boards are placed end to end to make a walkway.

Answer:
x = 7
Step-by-step explanation:
A rhombus is a parallelogram where all sides are equal. Therefore, as we know two sides are equal to 7x+8 and 9x-6, we can say that
7x+8 = 9x - 6
subtract 7x from both sides to put the variable on one side
2x - 6 = 8
add 6 to both sides to isolate the variable and its coefficient
2x = 14
divide both sides by 2 to isolate x
x = 7

Answer:
3*(8-5)=(3*8)-(3*5)
Answer:
I think it would be 3x(8-5)=(3x6)-(3x3)
Step-by-step explanation:
This is because if you answer the left side of the equation, it would be 9:
3x(8-5)
(8-5=3)
then 3x3=9
and on the right side of the equation, if you plug in 6 and 3 + solve the equation you would get 9:
(3x6)-(3x3)
18-9
=9
so all together it would be 9=9 which is true
meaning that the numbers 6, and 3 are the numbers you use to fill in the blanks (this is only one of the possible answers, there are many more!)
Not sure if all calculations are correct, but I hope this helps! :)

A building has a triangular rooftop terrace which is modeled by triangle A BC. In triangle A BC, the measure of XA is 55°. the measure of
XB is 65°, and the measure of C is 60°.
Which side of the terrace has the greatest length?
Considering the angles of the triangle, side AC has the greater length, as it is opposite to the greatest angle.
Which side has the greatest length on a triangle?It is the side that is opposite to the angle with the greatest measure.
In this problem, angle B has the greatest measure, of 65º, hence side AC has the greater length, as it is opposite to angle B.

PLEASE HELP ME GET ANSWER
Answer:
The second number is 90.
Step-by-step explanation:
The first statement isn't at all helpful when you start the problem. Three numbers add up to 185. Big deal. Hold that thought for later.
You need a place to start: think about some quantity to assign a variable name (letter) to. Look at the second statement.
The second number is 5 times the first. If x represents the first number, then 5 times that is 5x. So far, you have this:
x = first number
5x = second number
Next: The third number is 13 less than the second number. "13 less than" means to subtract 13 from something. But what? The second number.
5x - 13 = third number
Now the first statement is useful. All three numbers add up to 185.
x + 5x + (5x - 13) = 185
Combine like terms.
11x - 13 = 185
Add 13.
11x = 198
Divide by 11.
x = 18
Wait! Trick question. The problem asks for the second number, not the first.
5x = 5(18) = 90

A 4 lakhs
B 43 lakhs
C 4 crores
D 43 crores
→ C 4 crores
Explaination :
2 - Unit place
3-tens place
9- hundred place
6 - thousand place
0- ten thousand place
4 - lakh place
3 - ten lakh place
4 - crore place
hence , closest approximation of this number is 4 crores.
Approximation of number is 4 crores.
What is Approximation?Anything that is similar to something else but not exactly equal to it is an approximation. By rounding, a number can be approximated. By rounding the values contained within a calculation prior to performing the operations, it can be approximated.
Given census of a country is 43406932
Adjusting numbers to the closest 10, 100, 1,000
To rough to the closest ten, check out at the digit during the tens section.
Look at the digit in the hundreds column to approximate to the nearest hundred. Take a look at the digit in the thousands column to determine the nearest thousand.
so the number to the closest is crore
Hence the closest approximation of this number is 4 crores.

Step-by-step explanation:
Solve by completing the square
x² - 3x + 10 = 0
x² - 3x = -10
x² - 3x + 9/4 = -10 + 9/4 half of 3 and square the answer (half of 3 = 3/2
and square the number (3/2)² = 9/4
x² - 3x + 9/4 = -31/4
