Michelle delivers books to school libraries. her truck has a slide out ramp for unloading the books. the top of the ramp is 3 ft above the ground. the ramp itself is 5.2 ft long. what is the horizontal distance the ramp reaches
Answer:
4.2 ft
Step-by-step explanation:
We can assume that the truck is vertically straight, so this will make up the vertical side of the triangle.
This means that the triangle is a right triangle since a right angle will be formed with the ground and the 3 ft side.
Next, we have the ramp length which is 5.2 ft long. This will be the hypotenuse of the right triangle since the ramp is slanted.
We want to find the length of the horizontal leg of the right triangle, which will give us the horizontal distance the ramp reaches.
We can use the Pythagorean Theorem since this is a right triangle:
a² + b² = c² a and b are the legs, c is the hypotenuseSubstitute these values into the equation and solve for b.
(3)² + b² = (5.2)² 9 + b² = 27.04 b² = 18.04 b = 4.24735211632The horizontal distance the ramp reaches is 4.2 ft, parallel to the ground.
For an assignment, Jorge needs to translate a figure on a coordinate plane. A vertex of the figure is at (-2,5). After translation, that vertex is at (4,-2), as shown in the diagram

Step-by-step explanation: Have a good day
which one is correct?
Answer:
SSS or SAS
Step-by-step explanation:
Remark
Since the two diagonals bisect each other, you have created two sets of equal lines. If that is the case, then you could prove the equality of the triangles 2 different ways.
1) The angles at the center are vertically angles which makes them equal. Since they are equal, the triangles are congruent by SAS. Notice that the angle is between the 2 equal sides.
2) Since CD and AB are marked as being equal, the triangles are congurent by SSS.

A cylinder has a radius of 10 yards. Its volume is 3,454 cubic yards. What is the height of the cylinder?
Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
11 yard
Step-by-step explanation:
volume of a cylinder=πr²h ⇒ 3454=3.14×10²×h
⇒ h=3454/314=11 yard
Answer:
6,769.84 yards
Step-by-step explanation:
Find the circumference of a 11cm radius circle using pi 3.14
Answer:
69.08 cm
Step-by-step explanation:
circumference= 2πr = 2 × 3.14 × 11 cm
Answer:
69.12 cm
Step-by-step explanation:
C = 2πr
C = 2(3.14)11
C = 6.28(11)
C = 69.12 cm
Part A: Xavier needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the correctly written inequality to represent the number of cans, c, that Xavier must still collect (before solving)
A 64 + c ≥ 120
B 64 + c < 120
C c - 120 ≤ 64
Answer:
A
Step-by-step explanation:
He needs to collect at least 120 so if c is what he must still collect
64 +c must be greater than or equal to 120
Start at 4 3/4 and count on steps of 1/4. If 4 3/4 is the first number in the sequence write down the 3rd number and the 6th number and the 9th number
Answer:
5 1/4 ; 6 ; 6 3/4
Step-by-step explanation:
Using the nth term of an arithmetic progression relation.
an = a + (n - 1)d
First term, a = 4 3/4
Common difference, d = 1/4
3 rd term ; n = 3
a3 = 4 3/4 + (3 - 1)1/4
a3 = 4 3/4 + 2*1/4
a3 = 4 3/4 + 1/2
a3 = 5 1/4
6th term ; n = 6
a6 = 4 3/4 + (6 - 1)1/4
a6 = 4 3/4 + 5*1/4
a6 = 4 3/4 + 5/4
a6 = 6
9 th term ; n = 3
a9 = 4 3/4 + (9 - 1)1/4
a9 = 4 3/4 + 8*1/4
a9 = 4 3/4 + 2
a9 = 6 3/4

Given the function y=-\frac{3\sqrt{x^5}}{4},y=− 4 3 x 5 , find \frac{dy}{dx}. dx dy . Express your answer in radical form without using negative exponents, simplifying all fractions.
Given:
The function is:
[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]
To find:
The value of [tex]\dfrac{dy}{dx}[/tex].
Solution:
We have,
[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]
It can be written as
[tex]y=-\dfrac{3}{4}x^{\frac{5}{2}}[/tex] [tex][\because \sqrt[n]x=x^\frac{1}{n}][/tex]
Differentiate with respect to x.
[tex]\dfrac{dy}{dx}=-\dfrac{3}{4}\times \dfrac{5}{2}x^{\frac{5}{2}-1}[/tex] [tex][\because \dfrac{d}{dx}x^n=nx^{n-1}][/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{5-2}{2}}[/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{3}{2}}[/tex]
[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}\sqrt{x^3}[/tex]
Therefore, the value of [tex]\dfrac{dy}{dx}[/tex] is [tex]-\dfrac{15}{8}\sqrt{x^3}[/tex].

Raymond needs to cover the entire surface area of the square based pyramid with paper what is the minimum amount of paper he will need
Answer: 408 sq ft
Step-by-step explanation: You would need to use the surface area formula SA = 1/2LP + B. Note that L is the slant height, P is the perimeter of the base, and B is the area of the base. 11 is the slant height as shown in the image above, p is 48 since you add 12 + 12 + 12 + 12, and the area of the square will be 144 since 12*12 = 144. Once you substitute the numbers in their correct place, you should get SA = 1/2 (11)(48)+144 which gives you 408 sq ft. Hope this helps!

Please help! I don't know this question.
Answer:
B. 14/15
Step-by-step explanation:
I hope this helps.
Answer:
B: 14/15
Step-by-step explanation:
Here's why I say this:
The total is 120. 8 have a box meaning 112 do not have a box. The question is asking about those without a box, so 112 will be used. 112/120. Simply by dividing each the numerator and denominator, in this case by 8. The fraction left is 14/15

The product of two numbers is negative. What conclusion can you draw about the sign of the quotient of the same numbers? *
Answer:
The quotient is negative.
Step-by-step explanation:
The rules of signs for multiplication and division of two numbers are the same.
If you multiply or divide two numbers with the same sign (both positive or both negative), the answer is positive.
If you multiply or divide two numbers with different signs (one positive and one negative), then the answer is negative.
Since the product is negative, then the quotient is also negative.
Answer: The quotient is negative.

find the product of (3x+8)^2
Answer:
The product is 9x^2+48x+64
Step-by-step explanation:
Slope intercept form of (2,4) slope is 2
To write slope intercept form from a point, you take the 2 and covert it to 2/1, or rise/run form. Then you find the y-intercept. Now listen, this is very complicated. Ready? It's the y-coordinate. 4. Veery complicated.
So y=2/1+4
