There are 40 adults and 2 children had haircuts on Friday.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given the system of equation as;
x + y = 42
4x + 14y = 568
We need to solve, let 'x' = 42-y and substitute this expression for 'x' in the second equation to get:
4(42-y) + 14y = 568
168 - 4y + 14y = 568
168 + 10y = 568
10y = 400
y = 40
therefore, x = 2

A zookeeper is 6 1/4 feet tall. A young giraffe in his care is 9 3/8 feet tall how many times as tall as the zookeeper is the giraffe?
Answer: The giraffe is 1.5 times tall as the zookeeper.
Step-by-step explanation:
Given: Height of Giraffe = [tex]9\dfrac38\ feet =\dfrac{72+3}{8}\ feet =\dfrac{75}{8}\ feet[/tex]
Height of zookeeper= [tex]6\dfrac14\ feet =\dfrac{24+1}{4}\ feet =\dfrac{25}{4}\ feet[/tex]
Let n = number of times the giraffe is tall as the zookeeper.
[tex]n=\dfrac{\dfrac{75}{8}}{\dfrac{25}{4}}=\dfrac{75\times4}{25\times8} = 1.5[/tex]
Hence, the giraffe is 1.5 times tall as the zookeeper.

Find the surface area and volume of the figure. Round to the nearest tenth.
Answer:
SA=64
V=28
Step-by-step explanation:
formula for SA: 2(lw+hw+lh)
formula for volume: l*w*h
where
l-(length)=2
w-(width)=2
h-(height)=7
lets solve for SA first:
2(2*2+2*7+2*7)
2(4+14+14)
2(32)
64
SA=64
now lets solve 4 volume
v=lwh
v=2*2*7
v=28

Steve sold 252 fruit baskets for a school fundraiser. Evie sold 25 fruit baskets for each 100 baskets that Steve sold. How many fruit baskets did Evie sell?
Answer:
63 baskets
Step-by-step explanation:
Given data,
Steve sold = 252 baskets
Evie sold = 25 fruit basket for each 100 basket sold by Steve
So, Evie is selling 25% of baskets sold by Steve.
We can calculate the total number of basket sold by Evie by using following formula,
Evie total basket sold = Percent sold by Evie × Basket sold by Steve
By putting the value, we get
Evie total basket sold = 25% × 252
= 63 baskets
A shop sells 3 types of boots football boots rugby boots and hiking boots sales are usually sold in the ratio 6:2:3 last moth 24 football boots were sold how many boots in total was sold last week
Answer:
44
Step-by-step explanation:
The sum of the ratios is 6 + 2 + 3 = 11
Let b = total number of boots sold last week
If 24 football boots are sold, the equation representing this =
6/11 x b = 24
To solve for b, divide both sides by 11/6
b = 44 = total number of boots sold last week

Which graph represents f(x)=−2x2?
Answer:
a
Step-by-step explanation:
it has a negative number which causes the parabola to be a maximum as opposed to a minimum
Using parabola concepts, it is found that the graph that represents [tex]f(x) = -2x^2[/tex] is given by option A.
The graph of a second degree equation is a parabola.If the leading coefficient, that is, the term that multiplies [tex]x^2[/tex] is positive, the parabola is concave up.Otherwise, if the leading coefficient is negative, the parabola is concave down.
In this problem, we have [tex]f(x) = -2x^2[/tex], which has a negative leading coefficient, thus it is a concave down parabola, which is represented by option A.

Rational Number Arithmetic Kiran says that -2 <5. Do you agree with kiran? Explain or show your reasoning
Answer:
I agree with Kiran
Step-by-step explanation:
Given the inequality -2<5, I agree with Koran because all negative values are less than all positive values and reverse is never the case. Since. -2 is a negative value and 5 is positive value, hence -2 is less than 5 thereby making the inequality expression -2<5 to be correct.

$18, P = $200, r = ?, t = 1.5 years. Find the annual interest rate.
I = $60, P = $750, r = 4%, t = ?. Find the amount of time. (sorry I added this one as well the other time I asked this no responded but you don't have to answer this if you want)
Question 1)
Given
Interest I = $18
Principle P = $200
t = 1.5 years
To determine
Interest rate r = ?
Using the formula
[tex]P = Irt[/tex]
[tex]r=\frac{I}{Pt}[/tex]
susbtituting I = 18, t = 1.5 and P = 200
[tex]r=\frac{18}{\left(200\times 1.5\right)}[/tex]
[tex]r = 0.06[/tex]
or
r = 6% ∵ 0.06 × 100 = 6%
Therefore, we conclude that the interest rate required to accumulate simple interest of $18.00 from a principal of $200 over 1.5 years is 6% per year.
Question 2)
Given
Interest I = $60
Principle P = $750
Interest rate = 4% = 0.04
To determine
Time period t = ?
Using the formula to calculate the time period
[tex]P = Irt[/tex]
[tex]t\:=\:\frac{P}{Ir}[/tex]
[tex]t=\frac{60}{\left(750\times 0.04\right)}[/tex]
[tex]t = 2[/tex] years
Therefore, the time required to accumulate simple interest of $ 60.00
from a principal of $ 750 at an interest rate of 4% per year is 2 years.

In one day the National Civil Rights Museum in Memphis Tennessee admitted 321 people and collected $1590. The price of admission is $6 for adults and $4 for children under 13. How many adults and how many children were admitted to the museum that day?
Answer:
Step-by-step explanation:
a + c = 321
6a + 4c = 1590
c = 321 - a
6a + 1284 - 4a = 1590
2a = 306
a = 153
c = 168
