A teacher is making worksheets for the next unit. He can create 3 worksheets in an hour and has 10 worksheets already created from the previous year. Which of the following lengths of time worked will not be long enough for the teacher to have created 27 worksheets. * Check All That Are True*
6 hours, 10 hours, 8 hours, 2 hours, 4 hours
Answer:
2 hours, 4 hours
Step-by-step explanation:
So lets go over what we know.
There are already 10 worksheets created.
Every 1 hour 3 more are made.
27 worksheets need to be made.
Ok, the first thing we can do is subtract the amount of worksheets needed by the amount we laready have:
27-10
=
17
Now, lets divide the amount of worksheets we still need, by how many we make each hour:
17/3
=
Well, 3 goes into 15, 5 times. Then 2 is left. So we know it takes 5 2/3 hours to create all 27 worksheets.
Looking at the answers, 6 hours, 8 hours, and 10 hours would work. However 2 hours and 4 hours would not work.
Hope this helps! ;)

Answer:
what's the answer?
Step-by-step explanation:
given m||n, find the value of x
Answer:
x= 154°
I hope it's helps you
Answer:
x=154
Step-by-step explanation:
The figures provides us with a variable and the number 154.
In this situation, the value of x and the given angle are corresponding angles.
The theorem of corresponding angles states that if a transversal is cut by two parallel lines the corresponding angles are CONGRUENT.
When an angle is congruent, they are equal to each other.
So in this case, x=154, x≅154.
Hope it helps! :)
Jamya is making a rectangular blanket. The length of the blanket is 10inches greater than it's worth, W, in inches. Write the function, f(w), that describes the area, in square inches, of Jamya's blanket as a function of the width, w.
Answer: (w² + 10)inches²
Step-by-step explanation:
Since the width of the rectangular blanket is given as w and the length of the blanket is 10inches greater than it's width, therefore the length will be:
= 10 + w.
Therefore,
length = 10 + w
width = w
Area = length × width
Area = (10 + w) × w
Area = 10w + w²
Therefore, the area of the blanket will be (w² + 10)inches².
Mark is six years older than his brother Sam. The sum of their ages is 30. Let 'a' be Sam's age.
Answer:
a = 12 years
Step-by-step explanation:
Mark is 6 years older than his brother Sam. Now, we are asked to represent Sam’s age by a. This means that if Sam is a years old, Mark is (a + 6) years old.
The sum of their ages is 30, this means that when we add their ages together, we get the sum of thirty.
Mathematically this means a + a + 6 = 30
2a + 6 = 30
This is the equation needed to get a. To get a , we proceed to solve the equation to completion.
2a = 30 - 6
2a = 24
a = 24/2
a = 12
What is the volume of the rectangular prism?
I need a lot of help bro
Explain Jan’s error
Answer:
Please check explanations
Step-by-step explanation:
To find the volume of the surface area of a cone, we need to use the height and not the slant height of the cone
The slant height, the height and the base radius forms a right triangle with the slant height being the hypotenuse of this triangle
By Pythagoras’ theorem, the square of the hypotenuse (slant height) equals the sum of the squares of the two other sides
6.5^2 = 2.5^2 + h^2
h^2 = 36
h = √36
h = 6 cm
So we have the volume as;
V = 1/3 * pi * r^2 * h
where r in this case is base radius of 2.5 cm
V = 1/3 * pi * 2.5^2 * 6 = 39.3 cm^3

C: 48
D: 80
Answer:
The answer is C, 48
Step-by-step explanation:
Its the only answer that makes sense
Answer:
75
Step-by-step explanation:
1. Eliminate wrong answers
a. (boys 5 & girls 4) meaning the boys should have a higher number than girls (which is 60) this meaning that 48 and 61 can not be the correct answer.
5/4=x/60
x=(5/4)*60
x=75
Math rocks
Leaving it to the obvious chose(The answer is 75)

4. Ann bought four pens and three exercise books for a total of sh 17 while peter bought five
similar pens and two exercise books for a total of sh.16 find the cost of a pen and an exercise
book.
Answer:
pen = 2 book = 3
Step-by-step explanation:
p= pens
b=books
4p +3b =17
5p+2b=16
Multiply the first by 5
Multiply the second by -4
Add both (p variable will ce cancelled)
20p +15b = 85
-20p -8b = -64
7b = 21
b=3 (book =3)
Lets plug this in one of the equations
4p + 3x3 = 17
4p +9 0 19
4p = 8
p= 2 (pencil = 2)
8. Find the area of the triangle. (1 point) 16 ft 62 ft Not drawn to scale.
Answer:
Hello! Answer: 496
Step-by-step explanation:
When finding area for triangles we have to do base x height then divide by 2 so
62 x 16 = 992
992 ÷ 2 = 496
So 496 is our answer!
Answer:
A - 496
Step-by-step explanation:
formula for area of a triangle
[tex]a = \frac{bh}{2} [/tex]
where b = base length and h = height
The triangle shown has a base length of 62 ft and a height of 16 ft
That being said we plug in the given values into the formula
[tex]a = \frac{62 \times 16}{2} \\ 62 \times 16 = 992 \\ \frac{992}{2} = 496[/tex]
Hence the area of the triangle is 496 square feet

The area of a rectangular park is 300 sq.M. If the length of the park is 25 m, find the breadth. *
Answer:
Breadth = 12 m
Step-by-step explanation:
Area of a rectangle is given by the formula,
Area = Length × Width
Value of area and length of the rectangular park has been given in this question.
Therefore, by substituting these values in the formula,
300 = 25 × Width
Width = [tex]\frac{300}{25}[/tex]
= 12 m
Therefore, width or breadth of the rectangular park will be 12 m.

Answer:
x = √149
Step-by-step explanation:
Compartmentalize the odd figure into a rectangle (with sides 3 and 7) and a triangle (with sides 10 and x). Now, that you have a triangle, you can use the rectangle underneath to find the bottom side of the triangle--it is 7. The triangle that has been formed is a right triangle, so we can use the Pythagorean Theorem to find x, which is the hypotenuse.
10² + 7² = x²
100 + 49 = x²
149 = x²
√149 = x
Answer:
7√2
Step-by-step explanation:
Remark
Draw another line parallel to 7.
Move to the other end of 3
that makes the vertical leg on the left 10 - 3 = 7
You now have a smaller right triangle.
Equation
a = 7
b = 7
c = x
Solution
x^2 = 7^2 + 7^2
x^2 = 49 + 49
x^2 = 98
x^2 = 7 * 7 *2
sqrt(x^2) = sqrt(7 * 7 * 2)
The rule about square roots is for every pair of factors you can take one out of the square root sign and throw the other one away.
x = 7 sqrt(2)

Answer:
uiptyftyfkghfcytfghvchjcghcfgcjvbcfg
Step-by-step explanation:
Answer:
2nd option
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 75, b = b , h = b - 10, then
[tex]\frac{1}{2}[/tex] b(b - 10) = 75 ( multiply both sides by 2 to clear the fraction )
b(b - h) = 150 ← option 2
There is a hot market at school for used graduation gowns, in fact the price is growing exponentially! Last week I could have gotten one for $25, but today, one week later, the price is $37.50. What would the price be if I decide to wait to buy my graduation gown at graduation, six weeks from now?
Answer:
$100
Step-by-step explanation:
the equation to solve this is:
[tex]y=12.5x+25[/tex]
[tex]y=12.5x+25\\ =(12.5*6)+25\\ =75+25\\ =100[/tex]

A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height h (in feet) can be expressed as a function of time t (in seconds) by the equation h = -16t2 + 56t. How much time does the ball take to reach its highest point?
1.75 seconds B) 2.50 seconds C) 2.75 seconds D) 3.50 seconds
Answer:
1.75
Step-by-step explanation:
h(t) = -16t² + 56t
h'(t) = -32t + 56
To find time at max height equate h' to 0
0 = -32t + 56
t = 56/32 = 1.75 s
It takes 1.75 s to reach max highest point
