Answer:
695 revolutions
Step-by-step explanation:
Finding the number of revolutions is basically a units conversion problem. You want to translate miles to revolutions. We can do this by way of feet and inches. The circumference of the wheel is pi times the diameter.
1 mi = (1 mi) × (5280 ft)/(1 mi) × (12 in)/(1 ft) / (29π in)/(1 rev)
= (1·5280·12·1)/(1·1·29π) = (63360/(29π)) rev ≈ 695.45 rev
About 695 revolutions will be needed to make the bike travel 1 mile.

x²+4x=8
Step-by-step explanation:
x²+4x=8
rearrange
x² + 4x - 8 = 0
half of 4 is 2
so
x² + 4x + 2² - 2² - 8 = 0
do x² + 4x + 2²
multiplies to give 4 adds to give 4
2+ 2
(x + 2)²
(x + 2)² - 2² - 8

Answer:
Steak burgers = $4.50
Fries = $2.25
Step-by-step explanation:
Steak burgers = x; fries = y
-2 (3x + 2y = $18)
3 (2x + 3y = $15.75)
-6x - 4y = -36
6x + 9y = 47.25
5y = 11.25
÷5 ÷5
y = $2.25
3x + 2y = 18
3x + 2( 2.25 ) = 18
3x + 4.5 = 18
-4.5 -4.5
3x = 13.5
÷3 ÷3
x = $4.50

slope of 2.
2.
Write the equation of the
line in slope intercept form
that contains the points
(4,−2) and (2,5).
Answer:
1.[tex]y=2x+4[/tex]
2.[tex]y=1x+3[/tex]
Step-by-step explanation:
Given the following questions:
Question one:
Point A = (-1, 2) = (x1, y2)
m = 2
To find the answer we will use the formula to find the slope intercept, substitute the values and then solve for b.
[tex]y=mx+b[/tex]
[tex]m=2[/tex]
[tex]x=-1[/tex]
[tex]y=2[/tex]
[tex]2=2(-1)+b[/tex]
[tex]2\times-1=-2[/tex]
[tex]2=-2+b[/tex]
[tex]-2+2=0[/tex]
[tex]2+2=4[/tex]
[tex]4=b[/tex]
[tex]b=4[/tex]
[tex]y=2x+4[/tex]
The slope intercept form of the line that passes through (-1, 2) and has a slope of 2 is "y = 2x + 4."
Question two:
Point A = (-1, 2) = (x1, y1)
Point B = (2, 5) = (x2, y2)
To find the slope intercept form we must first find the slope using the formula to calculate slope or rise over run.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{5-2}{2--1}=\frac{3}{3}[/tex]
[tex]3\div3=1[/tex]
[tex]m=1[/tex]
Now that we have the slope, we will use the formula for slope intercept, substitute the values, then solve for b.
[tex]y=mx+b[/tex]
[tex]m=1[/tex]
[tex]y=2[/tex]
[tex]x=-1[/tex]
[tex]2=1(-1)+b[/tex]
[tex]1\times-1=-1[/tex]
[tex]2=-1+b[/tex]
[tex]-1+1=0[/tex]
[tex]2+1=3[/tex]
[tex]3=b[/tex]
[tex]b=1[/tex]
[tex]y=1x+3[/tex]
The line that passes through the points (4, -2) and (2, 5) in slope intercept form is indeed "y = 1x + 3."
Hope this helps.

For which values of c does the quadratic equation x^(2)-2x+c=0 have No real roots?
Answer:
c > 1
Step-by-step explanation:
Given equation: [tex]x^2-2x+c=0[/tex]
General form of quadratic equation: [tex]ax^2+bx+c=0[/tex]
We can use the discriminant to determine the value of c for which the equation has no real roots.
[tex]b^2-4ac < 0\implies \textsf{no real roots}[/tex]
From the given equation:
[tex]a=1[/tex][tex]b=-2[/tex][tex]c=c[/tex]Inputting these values into the discriminant formula:
[tex]\implies (-2)^2-4(1)(c) < 0[/tex]
[tex]\implies 4-4c < 0[/tex]
[tex]\implies 4 < 4c[/tex]
[tex]\implies 1 < c[/tex]
[tex]\implies c > 1[/tex]
Here
a=1b=-2Discriminant must be less than 0
[tex]\\ \rm\Rrightarrow b^2-4ac<0[/tex]
[tex]\\ \rm\Rrightarrow (-2)^2-4(1)(c<0[/tex]
[tex]\\ \rm\Rrightarrow 4-4c<0[/tex]
[tex]\\ \rm\Rrightarrow 4(1-c)<0[/tex]
[tex]\\ \rm\Rrightarrow 1-c<0[/tex]
[tex]\\ \rm\Rrightarrow 1<c[/tex]
[tex]\\ \rm\Rrightarrow c>1[/tex]
PLEASE HELP ME FOR QUESTION 25
Step-by-step explanation:
Hopefully this helps you,
So if A= 70 degrees, C will also 70 degrees.
The parallelogram will always equal 360 degrees, so 70(2) = 140.
Then 360 - 140 = 220.
Then divide 220 by 2, so 220/2 = 110.
Therefore angles B and D are 110 degrees.
So your answer,
C = 70 degrees
B and D = 110 degrees

What's the question ?
Julian forgot his bat when he left for baseball camp. His mother finds a box to ship it to him with the dimensions shown. If the bat measures 34 inches long, will the bat fit inside the box? Drag words to complete the statements about the diagonal of the base and the interior diagonal of the box. Words may be used once, more than once, or not at all.
Here are the words shorter than longer than equal to will not
The diagonal of the base of the box is
the bat.
The length of the interior diagonal of the box is
The bat will fit in the box if the length of the bat is less than the interior diagonal of the box
Julian's bat will not fit inside the box
How to determine if the bat can fit the box?From the complete question, the dimension of the box is:
32 in by 6 in by 8 in
Start by calculating the diagonal (d) of the base of the box using the following Pythagoras theorem
[tex]d^2 = 6^2 + 8^2[/tex]
Next, calculate the length of the interior diagonal of the box.
[tex]L = \sqrt{32^2 + d^2\\[/tex]
This gives
[tex]L = \sqrt{32^2 + 6^2 + 8^2}[/tex]
Evaluate
[tex]L = 33.53[/tex]
The length of the bat (34 inches) is greater than the interior diagonal of the box (33.53 inches)
Hence, the bat will not fit inside the box

Find the value of each variable in the parallelogram. Please help!
Answer:
m = 35 , n = 110
Step-by-step explanation:
the opposite angles of a parallelogram are congruent , then
2m = 70 ( divide both sides by 2 )
m = 35
consecutive angles are supplementary, that is sum to 180° , then
n + 70 = 180 ( subtract 70 from both sides )
n = 110
Solution:
We know that:
In a parallelogram, opposite angles are equivalentThis means that:
70 = 2mDivide 2 both sides to find m:
70 = 2m70/2 = 2m/2m = 70/2 = 35°We can see that two angles measuring 70° and n° are a linear pair.
n + 70 = 180n = 180 - 70 = 110°Find the distance between the points (2,5) and (10,5).
Answer:
8 units
Step-by-step explanation:
Points (2, 5) and (10, 5) have the same y-coordinate, so lie on the horizontal line y = 5. The distance between the points is the difference of their x-coordinates:
10 -2 = 8
The points are 8 units apart.

Justin is 74 inches and casts a shawdow that is 102 inches long. At the same time , a tree casts a shadow that is 39 feet long. How tall is the tree to the nearest foot?
Answer:
The tree is 28 feet in height.
Step-by-step explanation:
This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.
74 / x = 102/39 Cross Multiply
102x = 74*39 The inches as a unit cancel out.
102x = 2886 Divide by 102
x = 2886/102
x = 28.29 feet

Valerie drives 400 meters up a hill that makes an angle of 20° with the horizontal. To the nearest tenth of a meter, what horizontal distance has she covered?
425.7 meters
375.9 meters
1169.5 meters
136.8 meters
Answer:
For this case we can model the problem as a rectangle triangle.
We know:
Length of the hypotenuse
Angle between the base of the triangle and the hypotenuse.
We want to know:
Length of the base.
For this we use the following trigonometric relationship:
cos (15) = \frac{x}{500}cos(15)=500x
Clearing x we have:
x = 500 * cos (15) x = 482.96x=500∗cos(15)x=482.96
Rounding to the nearest tenth of a meter:
x = 483.0 mx=483.0m
Answer:
The horizontal distance she has covered is:
x = 483.0 mx=483.0m
Find the perimeter of the parallelogram with these vertices.
(6,4),(-1, 4), (1, -5), (-6, -5)
Answer:
34.6
Step-by-step explanation:
The perimeter of a plane geometric figure is the sum of its side lengths. This figure has two horizontal sides, so their length is easy to compute. It also has two diagonal sides, so the distance formula or Pythagorean theorem must be invoked to find their length.
The length of diagonal AC is ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((1 -6)² +(-5 -4)²) = √((-5)² +(-9)²) = √106 ≈ 10.3
The length of each horizontal segment can be found by counting grid squares or by finding the difference of x-coordinates.
AB = 6 -(-1) = 6 +1 = 7
__
Two sides have length 10.3 and two sides have length 7, so the perimeter is ...
P = 2(10.3 +7) = 34.6 . . . units
