Answer:
This question has incorrect answers but the answer that they are looking for is: 24 hours
Step-by-step explanation:
The average is the total hours divided by the number of weeks
So far Emily has 6 hours for the first 3 weeks, x is the number of hours she needs to work in the 4th week.
(6+x)/4=10
6+x = 40
x = 34
All the answers they gave are wrong because they did not account for the 4th week while taking averages.

Cora bought 90 feet of cable for $.25.20. She needs 40 more feet. If the unit price is the same, how much will she pay for the extra 40 feet of cable?
Answers
Answer: $11.2
Step-by-step explanation:
Given
Cora bought 90 feet cable for [tex]\$25.20[/tex]
So, the price of a foot is the division of rate and length
[tex]\Rightarrow \text{Price P=}\dfrac{25.20}{90}\\\\\Rightarrow P=\$0.28\ \text{per foot}[/tex]
for additional 40 feet, the cost is
[tex]\Rightarrow 0.28\times 40\\\Rightarrow \$11.2[/tex]
Thus, Cora pays $11.2 for extra 40 feet

Halla dos numeros enteros sabiendo que al sumarlos se obtiene (-9) y que el mayor de ellos menos 5 es igual al menor
Answers
Respuesta:
-7 y - 2
Explicación paso a paso:
Dejemos que los dos números = x y y
x = mayor
y = menor
x + y = - 9 - - - (1)
x - 5 = y - - - (2)
Ponga y = x - 5 en (1)
x + (x - 5) = - 9
x + x - 5 = - 9
2x - 5 = - 9
2x = - 9 + 5
2x = - 4
x = - 4/2
x = - 2
Ponga x = - 2 en y = x - 5
y = - 2 - 5
y = - 7

NEED HELP WILL BRAINLIST AND 10 points
Answers
Answer:
-4, -2, 6, 10, 12
Step-by-step explanation:
The function is h(x) = 2x + 4. H(x) is basically just another way of writing "y", so we technically have y = 2x + 4. We can complete the table by substituting the value of x that the table gives us.
The table gives us x = -4 and wants us to find h(x), or y. So, we do y = 2(-4) + 4 and we get y = -4.
The table gives us x = -3 so we do y = 2(-3) + 4 and we get y = -2.
The table gives us x = 1 so we do y = 2(1) + 4 and we get y = 6.
The table gives us x = 3 so we do y = 2(3) + 4 and we get y = 10.
The table gives us x = 4 so we do y = 2(4) + 4 and we get y = 12.

Find the area of a square with a diagonal of length 12.

Answer:

Step-by-step explanation:
Answer:
72 square units
Step-by-step explanation:
you can use the Pythagorean Theorem; because we're dealing with a square then each side can be assigned the same variable, let's use 'a'
a² + a² = 12²
2a² = 144
a² = 72
a = [tex]\sqrt{72}[/tex]
[tex]\sqrt{72}[/tex] can be simplied as [tex]\sqrt{9}[/tex]·[tex]\sqrt{4}[/tex]·[tex]\sqrt{2}[/tex] which is 3·2·[tex]\sqrt{2}[/tex]
each side has a length of 6[tex]\sqrt{2}[/tex]
A = (6[tex]\sqrt{2}[/tex])² which is 6·6·2 or 72

Answers
Answer:
D
Step-by-step explanation:
The horizontal cross-sections of the prisms which is at same height as the cone should have same area.
Therefore Option D is the answer.
What is a Cone ?A cone is a three dimensional figure that has a circular horizontal structure , and vertically tapering up till a point.
It is given that
A Pyramid and a cone both have same volume.
Height of cone is same as Height of Pyramid .
Volume of cone = (1/3)πr²h
Volume of a pyramid = Area of base * h
When both the volume are equated
as height is same
The Area of the base of the cone = Area of the base of the Pyramid
The horizontal cross-sections of the pyramid which is at same height as the cone should have same area.
Therefore Option D is the answer.

Shannon rolls two number cubes, each numbered one through six. She observes the numbers facing up on each number cube and finds the total of the two numbers. What is the probability the total will be 5?
Answers
starting with 2 cubes that have 6 numbers total for each one, so 2 cubes will have 12 numbers total, and the probability of number 5 is 2/12 (because each cube has a number 5, so two cubes will have 2, and fraction for it will be 2/12).
The probability the sum total will be 5 is 4/36.
What is probability?"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one".
For the given situation,
The sample space for rolling two 6 sided cube is
s ={
[tex](1,1), (1,2), (1,3), (1,4), (1,5), (1,6)\\(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)\\(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)\\(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)\\(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)\\(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)[/tex] }
⇒ [tex]n(s)=36[/tex]
The event is getting the probability that the sum total will be 5.
e = { [tex](1,4), (2,3), (3,2), (4,1)[/tex] }
⇒ [tex]n(e)=4[/tex]
Thus the probability that the sum total will be 5 is
[tex]P(e)=\frac{n(e)}{n(s)} \\[/tex]
⇒ [tex]P(e)=\frac{4}{36}[/tex]
Hence we can conclude that the probability the sum total will be 5 is 4/36.
