Answer:
The total length of the trip was 400 miles.
Step-by-step explanation:
He fell asleep at 44% through the trip, they already had traveled 176 miles.
.44x = 176 ⇒
176 ÷ .44 ⇒
x = 400
The total length of the trip was 277 miles when Dalvin fell asleep after they had traveled 176 miles.
What is the distance?A mathematical number known as distance measures "how much ground an object has traveled" while moving. Distance is defined as the product of speed and time.
If Dalvin fell asleep 44% of the way through the trip, then the total length of the trip is 100% - 44% = 56% longer than the distance Dalvin's family had traveled when he fell asleep.
The total length of the trip is therefore 1.56 times the distance that Dalvin's family had traveled when he fell asleep.
Since Dalvin's family had traveled 176 miles when he fell asleep, the total length of the trip is 1.56 x 176 miles = 277 miles.
Therefore, the total length of the trip was 277 miles.

i need help with this question please
Answer:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

SOLVE FOR x IN THE DIAGRAM BELOW
Answer:
x = 12°
Step-by-step explanation:
(x + 42) + 3x = 90°
(The interior angle equals 90°)
Simplify.
4x + 42 = 90
Subtract.
4x = 48
Divide.
x = 12°
good luck, i hope this helps :)
Answer:
x= 12°
Step-by-step explanation:
Information needed:
The two angles add up to 90°
Equation: (x+42)+3x= 90°
Solve:
(x+42)+3x= 90°
x+42+3x= 90°
x+3x+42= 90°
4x+42= 90°
-42 -42

Of the 120 math tests, 47 were Bs. What percent of the math tests were Bs? Round to the nearest whole percent.
Answer:
39.17%
Step-by-step explanation:
Answer:
39%
Step-by-step explanation:
Percent is ALWAYS out of 100, and the unknown is percent so our first part of the equation will be %/100. Now our second part of equation: is/of
Of represets whole the total, and we have our key word “Of the 120 math tests”. We have our total: 120; 47 is our part so second part of equation: 47/120.
Our equation so far: %/100 = 47/120 now we need to multiply the numbers that we have diagonally: 100% x 47; 47/100 we’re multiplying so we’ll move two 0s to the right. Answer: 4700
Now, we’ll divide 4700 by 120. 4700/120. Answer: 39.1666666667. Round to nearest whole means round to nearest ones.
Thus, the answer is 39.

Explain relationship between the factors of a quadratic expression, the roots of the related quadratic equation, and the x-intercepts if the graph of the related function
Step-by-step explanation:
So, let's use x2 - 3x - 28 as an example.
It's factors are (x - 7)(x + 4).
The roots are the x-values that make our expression equal 0. In order for x2 - 3x - 28 to equal 0, either of our factors need to equal 0, since 0 times anything is 0.
x2 - 3x - 28 = 0
(x - 7)(x + 4) = 0
x - 7 = 0
x = 7
(7 - 7)(7 + 4) = 0(11) = 0
x + 4 = 0
x = -4
(-4 - 7)(-4 + 4) = -11(0) = 0
That gives us two points on our graph, (7,0) and (-4,0). Where are those? On the x-axis! Thus, there are our x-intercepts.
By the way, for the future, along the x-axis, y = 0, so if you are asked for the x-intercepts (or roots), set y = 0 and solve for x.
Along the y-axis, x = 0, so if you are asked for the y-intercepts, set x = 0 and solve for y.
y = 02 - 3(0) - 28
y = -28
So, the y-intercept(s) of our same equation is y = -28, or (0,-28).
Boom.
Answer:
The x-intercepts are happen are when y = 0. If you tried to substitute y = 0 into a quadratic in the standard form you can not use traditional methods for solving for x.
Y=0 when looking for an x-intercept. Doing the factored form you are finding the x-intercepts. You always want the equation to equal 0 then factor out the equation till you get the numbers for the x-intercept.

DeAngelo rode his bike at a rate of 12 miles per hour. At that rate, how far could he ride in three hours?
At the given rate, he could ride 36 miles in three hours
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
DeAngelo rode his bike at a rate of 12 miles per hour.
At that rate,
He rode in three hours,
= 3 x given rate
= 3 x 12
= 36
