Jeremy goes on a bike ride for 45 minutes per day during the summer. At the end of the summer, he has rode his bike for 2,475 minutes. How many days did he ride his bike? He rode days.
Answer:
55 days
Step-by-step explanation:
1 day = 45 minutes
=> x days = 2475 ÷ 45
=> x days = 55 days
Therefore, he had rode 55 days in the whole summer.

Find the angle measure of X, Y, and Z
Answer:
x=33
y=134
z=46
Step-by-step explanation:
Lets solve for Z first. It is in a triangle with 2 angles already known: 84 and 50. Because the 3 angles in all triangles add to 180...
z+50+84=180
z=180-50-84
z=46
Angles z and y are supplementary, because they exist on the same line and are cut off by one line segment. This means that their angles add to 180.
180=y+z
we already know that z=46
180=y+46
y=180-46
y=134
Now we can use the same rule we used to find z, to find x.
x+y+13=180
we just found that y=134
x+134+13=180
x=180-134-13
x=33

cardboard rectangle. He folds the remaining cardboard to make
a tray that is x in. high. Write and simplify a function for the volume
V of the tray in terms of x.
HELP
Answer:
V(x) = 4x³ - 50x² + 150Step-by-step explanation:
Initial area is 10 in x 15 in.
After cutting the corners and folding, the remaining dimensions are:
Length, l = 15 - 2xWidth, w = 10 - 2xHeight, h = xThe volume of the tray is:
V = lwhV(x) = (15 - 2x)(10 - 2x)x = 4x³ - 50x² + 150Solve this equation by factoring by grouping x^2-4x=12. All work must be shown and no other method will be accepted.

Question 5
Solve for b.
−1/3b=9
b=−27
b=−3
b = 3
b =27
Answer:
1) 2 5/12
2) -3 1/30
3) 3/5
4) m = -28
5) b = -27
Step-by-step explanation:
1) You may be expected to solve this a different way, but how I prefer to solve these involves converting to "improper fractions", then making everything whole.
-11/3 = x - 5/4 (convert to improper fractions)
-44 = 12x - 15 (multiply everything by 12 to get whole numbers)
-29 = 12x (add 15 to both sides)
-29/12 = x (divide both sides by 12)
2 5/12 = x (convert to a mixed number, because that's what the question asks)
For clarity, that's two and five twelfths.
2) Same thing as above. I prefer improper fractions.
x + 17/6 = -1/5 (simplify and convert to improper fractions)
30x + 85 = -6 (multiply everything by 30 to get whole numbers)
30x = -91 (subtract 85 from both sides)
x = -91/30 (divide both sides by 30
x = -3 1/30 (convert to a mixed number, because that's what the question asks)
For clarity, thats minus/negative three and one thirtieth.
3) Same thing as above.
-(11/3)x = -11/5
-55x = -33
55x = 33
x = 33/55
x = 3/5
4) Same as above, but it's multiple choice! Yay!
-3m = 84
m = -28
5) You know the drill.
-b = 27
b = -27
I'd be happy to explain more if you need it at all. I'd recommend that next time this comes up, you post just one problem and see if you can understand the method so you can better learn how to do it on your own. Good luck (:

Which of the following is the maximum value of the function y = −2x^2 + 5?
A. 0
B. 25
C. −2
D. 5
Answer:
A. 0 because 5 is the minimum
Step-by-step explanation:
Use the formula
x = − b /2 a
to find the maximum and minimum.
( 0 , 5 )
Multiple x² by -1 would flip it across x-axis so -x² would have maximum value 0. Now multiplying -x² by 2 stretch it vertically, however 2 times 0 is still 0 so maximum value is still 0. Now we add it by 5 which makes it shifts 5 units up, so this affects maximum value. So everything will be shifted 5 units up, so new maximum would be 5. Final 5

What is an equation of the line?A line equation is defined as a linear equation with a degree of one. The line equation has two variables, x and y. The third parameter is the line's slope, which represents the line's elevation.
The following is the general form of the line equation:
y = mx + c
m = slope
c = y-intercept
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
Calculate the slope of the line:-
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m = \dfrac{ -2 + 1 } { -3 - 5 }[/tex]
[tex]m = \dfrac{1}{8}[/tex]
The y-intercept will be:-
y = mx + c
[tex]-2 = \dfrac{-3}{8} + c[/tex]
[tex]c = \dfrac{-13}{8}[/tex]
The equation can be written as:-
y = mx + c
[tex]y = \dfrac{1}{8} x- \dfrac{13}{8}[/tex]

If we want the area to be more than 225 sqft, and the width is already established as 25, then we can divide 225 by 25 to see what the minimum would be. 225/25 is 9, so this is the minimum. We want a set of possible lengths though, and as long as the pen is over 225 sqft, it's allowed. Therefore, the answer is [tex]x\geq 9[/tex].

How to solve: 10 x -7 = 4x + 5
[tex]10x -7 = 4x+5 \\\\\implies 10x -4x = 5+7 \\\\\implies 6x = 12 \\\\\implies x = \dfrac{12}6 =2[/tex]
~one variable linear equation
===============================
10x - 7 = 4x + 5
= 10x - 7 - 4x = 5
= 10x - 4x = 5 + 7
= 6x = 5 + 7
= 6x = 12
= x = 12 ÷ 6
= x = 2 ✔️

I dont understand this question
-32=8m
Answer:
m= -4
Step-by-step explanation:
the question is asking you to make the variable 'm' by its self and find what it is equal to. you divide 8 by both sides. this gets 'm' alone and -32 divided by 8 is -4.
What is the equation in slope-intercept form of the line that passes through the point (-2,3) and is parallel to the line represented by y= - 3/4x + 4?
Answer:
[tex]y = \frac{-3}{4}x + \frac{3}{2}[/tex]
Step-by-step explanation:
Because is a line the equation is of the form
[tex]y = mx + b[/tex]
Since both lines are parallel the slope of both equations are the same
[tex]y = \frac{-3}{2}x + b[/tex]
Now for find the unknow [tex]b[/tex] replace the [tex]x[/tex] and [tex]y[/tex] fo the given point.
[tex]3 = (\frac{3}{4}) 2 + b[/tex]
[tex]3 = \frac{3}{2} + b[/tex]
[tex]3 - \frac{3}{2} = b[/tex]
[tex]\frac{3}{2} = b[/tex]
So the final equation is equal to
[tex]y = \frac{-3}{4}x + \frac{3}{2}[/tex]

3. The triangular prisms shown below are similar. What are the values of x and y? 14cm X 20 cm > 4 cm 8 cm X:
Applying similarity of triangles, the values of x and y are given as follows:
x = 7 cm.y = 10 cm.Similar trianglesSimilar triangles have congruent angle measures, thus the measures of the side lengths are proportional. This relation can be proven from the law of sines.
In this problem, we have two triangular prisms which are similar, and the equivalent side lengths are presented as follows:
14 cm and x.8 cm and 4 cm.20 cm and y.Hence the following proportional relationship is established with the side lengths:
14/x = 8/4 = 20/y.
Applying cross multiplication with the middle term, the measure of x is calculated as follows:
14/x = 8/4
14/x = 2
2x = 14
x = 14/2
x = 7 cm.
The measure of y is calculated as follows:
20/y = 8/4
20/y = 2
2y = 20
y = 20/2
y = 10 cm.
Missing InformationThe triangular prisms are given by the image at the end of the answer.

Answer
y = -88x + 99
Step-by-step explanation
Step 1: Find the slope by doing the rise over run equation, which is y2-y1 / x2-x1. Plug in x and y numbers based on the table. So, the slope (m) = -88.
Step 2: Figure out the real equation: y=mx+b. Plug in numbers that you have to find the missing number, the y-intercept (b).
y=mx+b --> 11 = -88 * 1 + b --> 99 = b
Step 3: Plug everything into the y=mx+b equation.
