Sandi lives 5 miles from her school. One day, she took the bus from her house to school. After school, she went to the library to pick out a book. Then she went to the park to read. If sandi traveled along the route shown, how far did she travel.
Her house to school is 5 miles.
The distance on the map is 2.5 inches, so we know 2.5 inches equals 5 miles.
Divide 5 miles by 2.5 inches to find miles per inch:
5 / 2.5 = 2 miles per inch.
Now you can multiply the other dimensions on the map by 2 to find total miles:
School to Library = 3 x 2 = 6 miles.
Library to Park = 1.5 x 2 = 3 miles.
Total distance traveled: 5 + 6 + 3 = 14 miles.
Given f(x) = 10 -2xfind f(7). –4 3 7 56
Answer: [tex]f(7)=-4[/tex]
Step-by-step explanation:
1. You have the following function given in the problem:
[tex]f(x)=10-2x[/tex]
2. Then, to find [tex]f(7)[/tex] asked in the exercise, you only need to substitute [tex]x=7[/tex] (which is the input value) into the given function.
3. Therefore, keeping the above on mind, you obtain that [tex]f(7)[/tex] is:
[tex]x=7[/tex]
[tex]f(7)=10-2(7)[/tex]
[tex]f(7)=10-14[/tex]
[tex]f(7)=-4[/tex]
Answer:
The correct answer is,
f(7) -4
Step-by-step explanation:
It is given that,
f(x) = 10 - 2x
To find f(7)
To find f(7) we have to put 7 instead of x in f(x).
Here f(x) = 10 - 2x,
Step 1: substitute the value x = 7 we get ,
f(7) = 10 - (2 * 7)
= 10 - 14 = -4
Therefore we get the answer f(7) = -4

Area of a triangle is 0.5(base x height)
Base = 320mi
Height= 270+210= 480mi

solve x^2+10x=24 by completing the sqaure. which is the solution set of the equation
Answer:
{-12, 2}
Step-by-step explanation:
x^2 + 10x = 24
Take half of the x-term coefficient and square it. Add that to both sides.
Half of 10 is 5. 5^2 = 25.
x^2 + 10x + 25 = 24 + 25
(x + 5)^2 = 49
x + 5 = +/-sqrt(49)
x + 5 = 7 or x + 5 = -7
x = 2 or x = -12
{-12, 2}

well, we have a missing point of R, but since is part of one of the tangent lines, we can safely assume is the point where the PR of 5 inches is at.
what is the angle at point R? namely the ∡SRP, well, SR is a tangent, RP is a radius line, they both touch/intersect at point R, thus R is the point of tangency for those two, and the point of tangency is always a 90° angle.

350-40x>40
Now you subtract 350 from both sides. -40x is greater than negative 310. Divide by -40 on both sides and flip the sign since you are dividing by a negative. x<31/4 or 7.75, so round down and she can only have 7 exhibits
Answer:
she can have at most seven exhibits
Step-by-step explanation:
do 350-40 because that is the amount of space needed for a walkwaynext do 310/40 because that is the amount of space is needed for each exhibitround 7.75 down because you can't have part of an exhibit:)Juan pulled a red card from the deck of regular playing cards.

A sphere and a cylinder have the same radius, and the height of the cylinder is equal to its radius; which figure has the greater volume?
Given a sphere and a cylinder with the same radius, r, and the height of the cylinder equal to the radius, the sphere has a greater volume. This is concluded by comparing the volume formulas for a sphere (4/3πr³) and a cylinder (πr³).
Explanation:The sphere and cylinder have the same radius, r, and the height of the cylinder, h, is equal to its radius, r. We'll calculate the volumes of both an apply our given conditions to see which figure has a greater volume.
The formula for the volume of a cylinder is Vcylinder = πr²h. In this case given that h=r, it becomes Vcylinder = πr³.
The formula for the volume of a sphere is Vsphere = 4/3πr³.
Comparing both, we definitely see that the sphere with a volume of 4/3πr³ is greater than the cylinder with a volume of πr³

Jacob made a banner for a sporting event in the shape of a parallelogram. The area of the banner is 127 1/2 square centimeters. The height of the banner is 4 1/4 centimeters. What is the base of the banner?
Answer:
30 cm
Step-by-step explanation:
The area of a parallelogram is given by [tex]A=bh[/tex]
Where
A is the area
b is the base, and
h is the height
Since A and h are given, we plug that in and find the base. Shown below:
[tex]A=bh\\127\frac{1}{2}=b(4\frac{1}{4})\\b=\frac{127\frac{1}{2}}{4\frac{1}{4}}\\b=\frac{\frac{255}{2}}{\frac{17}{4}}\\b=\frac{255}{2}*\frac{4}{17}=30[/tex]
Hence, the base is 30 centimeters

Answer:
General quadratic form is 17x²- 12x + 0 = 0.
Step-by-step explanation:
Given : 17x² = 12x.
To find : Write the quadratic equation in general quadratic form below.
Solution : We have given that 17x² = 12x.
General quadratic form is : [tex]ax^{2} + bx + c = 0[/tex].
We have 17x² = 12x.
Convert it in to general quadratic form
On subtracting both sides by 12x .
17x²- 12x + 0 = 0.
Here a = 17 , b = - 12 , c = 0 .
Therefore, General quadratic form is 17x²- 12x + 0 = 0.
n edge of Cube A is 8 inches, and an edge of Cube B is 5 inches. To the nearest tenth, how many times greater is the volume of Cube A than Cube B?

what you do is take 5 away from 3. No! Borrow 1 Whole (9) and makes it 9 13/8 - 8 5/8 then subtract the 2 fractions
[tex] \frac{13}{8} - \frac{5}{8} ...[/tex]
and that is
[tex] \frac{8}{8} [/tex]
then convert that into 1 whole. Now add the whole to the 9 and thats 10. Now, subtract the 2 whole numbers. 10-8=2 so the answer is 2

Answer:
x = -3/4 and 7/2 will be your final answer, but check below for a correction on your work
Step-by-step explanation:
***Your work is incorrect, it should be
2x² - 11x - 21 = 0
you need to subtract an 'x' from both sides, and add 5 to both sides...you added an x to the left side and subtracted a 5 from the left side instead***
I'll solve this so in case you will need help on it too.
Now you'll have
x = (11 ± √[(-11²) - 4(2)(-21)])/([4(2)]
x = (11 ± √289)/8
x = (11 ± 17)/8
x = (11 + 17)/8 = 28/8 = 7/2
or
x = (11 - 17)/8 = -6/8 = -3/4

Kay was walking along the bridge above the river. She accidentally lost her grip on her camera when she was trying to get it out to photograph massive birds nest in the trees.The height of the camera above the water can be modeled by the equation y=-16t^2+400, where t represents the seconds after the camera is dropped. How long will it take before Kay sees the splash from the camera hitting the water.
Answer:
5 seconds it will hit the water.
Step-by-step explanation:
y=-16t²+400
add -16t² to both sides
-16t²=-400
divide both sides by 16
t²=-25
t=√25
t=5
Answer:
t=5
Step-by-step explanation:
t=√25=t=5

7 POINTS!!! ~ A 6 foot tall man casts a shadow that is 4.5 feet long. A telephone pole casts a shadow that is 15.6 feet long. Two similar triangles are created. How tall is the telephone pole?
The answer is:
The telephone pole is 20.8 foot tall.
Why?Since it's not mentioned, we can assume that both, man and the telephone pole are close, so, if two similar triangles are created, we know that both shadows are proportional and we can find the telephone pole height creating a proportionality relationship.
We can find the telephone pole height using the following equation,
[tex]\frac{ManHeight}{ManShadow}=\frac{PoleHeight}{PoleShadow}[/tex]
Were,
Man height is 6 foot
Man shadow is 4.5 feet long
Telephone pole shadow is 15.6 feet long.
So, substituting we have:
[tex]\frac{6}{4.5}=\frac{PoleHeight}{15.6}[/tex]
[tex]PoleHeight=15.6*\frac{6}{1.5}=20.8ft[/tex]
So, the telephone pole is 20.8 foot tall.
Have a nice day!

Answer:
The answer in the procedure
Step-by-step explanation:
we have
x+2y > 6
Isolate the variable y
y > -0.5x+3
The solution of this inequality is the shaded area above the dashed line
The equation of the dashed line is y=-0.5x+3
The slope of the dashed line is negative (m=-0.5)
The y-intercept of the dashed line is 3 (value of y when the value of x is equal to zero)
The x-intercept of the dashed line is 6 (value of x when the value of y is equal to zero)
Plot the intercepts to draw the dashed line and shaded the area above the dashed line

8 divided by 2=4 then square the 4
16
Answer:
16
Step-by-step explanation:
A perfect square trinomial is a three-term polynomial (also called a trinomial) that results from squareing a binomial. Every trinomial of the form: [tex]a^{2} +2ab+b^{2}[/tex], It is a perfect square trinomial.
In this case, it is necessary to divide the intermediate value of 8 by 2, and then square it, obtaining the result.
