Answer:
Step-by-step explanation:
Here the function is y = 5x.
If x = -2, y = 5(-2) = -10;
If x = 0, y = 5(0) = 0; and
If x = 9, y = 5(9) = 45
And so on
If y varies jointly as x and z and y = 4 when x = 2 and z = 3, what is y when x = -6 and z = 2?
Answer:
Step-by-step explanation:
Y = kxz
Putting values of y x and z in the equation
4 = k(2)(3)
4 = k6
2/3 = k
Now finding y when x = - 6 and z = 2
Y = kxz
= 2/3(-6)(2)
= - 8

Q2) for both of the following, calculate A5 and A100.
(i) An= 6n-3
Answer:
27 and 597
Step-by-step explanation:
To evaluate A5 and A100, substitute n = 5, n = 100 into An , that is
A5 = 6(5) - 3 = 30 - 3 = 27
A100 = 6(100) - 3 = 600 - 3 = 597
Answer:
5n=6n-3
C.L.T
6n-5n=3
n=3
ii.100n=6n-3
C.L.T
100n-6n= -3
94n/94=-3/94
n=-0.032

What is the surface area of this triangular pyramid the height is 4 the base and width is 4 and the bottom back line is 4 and the base height is 3.5 yd.
Answer:
37 yd²
Step-by-step explanation:
The computation of the surface area of this triangular pyramid is shown below:
The surface area of this triangular pyramid is
But before that
Lateral area = 3(1 ÷ 2) × base × height
= (3 ÷ 2)(4 yd)(5 yd)
= 30 yd²
Now
base area = 1 ÷ 2 × base × height
= 1 ÷ 2(4 yd)(3.5 yd)
= 7 yd²
Now the total surface area is
surface area = lateral area + base area
= 30 yd² + 7 yd²
= 37 yd²

Answer: Yes, they are similar
Step-by-step explanation:
Angle A is congruent to angle D
Angle B is congruent to angle E
Angle C is congruent to angle F
Therefore, the triangles are similar by the AAA (angle-angle-angle) similarity theorem.

Step-by-step explanation:
Sam is a cashier at the local grocery store. He earns $8/hr and works there 10 hours per
week. Every week, he puts 75% of his money in a savings account so he can reach his goal
of having $1,000 as an emergency fund. School is starting in a few weeks and he wants to
buy some new supplies including a backpack, pens and notebooks, and more. He
estimates the total will be about $75.
T
Answer:
A. $80
B. $60
C. 4 Weeks
D. Sam might have to work more at his work or possibly lower the amount of money he needs to save.
Step-by-step explanation:
Hope this Helps!!
The number of weeks taken by Sam to save enough money is 17 weeks.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
a) Money Sam earns in one week = Money paid per hour * Number of hours per week
= 8×10
= $80
b) Money saved every week is
75% of 80
= 75/100 ×80
= 0.75×80
= $60
c) He can reach his goal of having $1,000 as an emergency fund.
Let the number of weeks taken by Sam to save enough money be x.
Now, 60x=1000
x=1000/60
x=17 weeks
d) School is starting in a few weeks and he wants to buy some new supplies including a backpack, pens and notebooks, and more.
He estimates the total will be about $75.
So, Sam has to work one week extra to purchase his needs for school.
Therefore, the number of weeks taken by Sam to save enough money is 17 weeks.

Find the GCF of the group of monomials
9a^2b^3 and 15ab^2 and 21a^4b^3
Answer:
3ab^2
Step-by-step explanation:
The GCF of 9, 15, and 21 is 3.
The GCF of a^2b^3, ab^2, and a^4b^3 is ab^2.
The answer is the product of the two terms which is 3ab^2.
Suppose we want to choose 3 objects, without replacement, from the 4 objects pencil, eraser, desk, and chair.
(a) How many ways can this be done, if the order of the choices is relevant?
?
(b) How many ways can this be done, if the order of the choices is not relevant?
Answer:24 , 4
Step-by-step explanation:
Given
There are 4 objects
(a)When the order is relevant
We use permutation to get the no of ways, that is
Choosing 3 objects out of 4
[tex]^4P_3=\dfrac{4!}{(4-3)!}=\dfrac{4!}{1!}\\^4P_3=24[/tex]
(b) When the order is not important, the same thing can be done in
[tex]^4C_3\ \text{ways}\\\\\Rightarrow \dfrac{4!}{1!3!}=4\ \text{ways}[/tex]

The x-coordinate of the vertex of the function y=-x²+bx+3 is 10. Determine the y-coordinate of the vertex.
Answer:
103Step-by-step explanation:
Given function:
y = -x² + bx + 3The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = -b/2aThe given function has:
x = 10, and a = -1Find the value of b:
10 = -b / -2b = 20The function is:
y = -x² + 20x + 3The y-coordinate of the vertex is:
y = -(10²) + 20*10 + 3 = -100 + 200 + 3 = 103Answer:
Solution given:
y = -x² + bx + 3
we have
The x-coordinate of a quadratic function y = ax² + bx + c is determined by:
x = [tex] \frac{ - b}{2a} [/tex]
we have
x = 10, and a = -1
Substituting value of a in -b/2a
we get
b = 20
now
The y-coordinate of the vertex is:
y = -(10²) +20*10+ 3 = -100 + 200 + 3 = 103 is your answer.

Answer:
50%
Step-by-step explanation:
Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 30 feet and a height of 16 feet. Container B has a diameter of 22 feet and a height of 20 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full. To the nearest tenth, what is the percent of Container A that is full after the pumping is complete?
Answer:
32.8%
Step-by-step explanation:
Container A:
Diameter = 30 feet
Radius = diameter/2 = 30/2
= 15 feet
Height = 16 feet
Volume of a cylinder = πr²h
= 3.14 * 15² * 16
= 3.14 * 225 * 16
= 11,304 feet ³
Container B:
Diameter = 22 feet
Radius = diameter / 2
= 22/2 = 11 feet
Height = 20 feet
Volume of a cylinder = πr²h
= 3.14 * 11² * 20
= 3.14 * 121 * 20
= 7598.8 feet ³
what is the percent of Container A that is full after the pumping is complete?
Container A - container B
= 11,304 feet ³ - 7598.8 feet ³
= 3,705.2 feet ³
percent of Container A that is full after the pumping is complete = 3,705.2/11,304 × 100
= 0.328 × 100
= 32.8%
percent of Container A that is full after the pumping is complete = 32.8%
