a rectangle has an area of 651m². One of the sides is 7m in length. Work out the perimeter of the rectangle
Answer:
200
Step-by-step explanation:
So first off, let's find the other side.
651 divided by 7 = 93
93 would be the other side measurement. There are two sides that measure 93 degrees, two sides that measure 7 degrees.
93 + 93 + 7 +7 = perimeter
Once we add up like terms, 200

60≥22x-8
22x+8≤60
22-8x≥60
22+8x≤60
Answer:
I believe the answer is D.
Step-by-step explanation:
22= jeans 8x= 8 dollars PER shirt
All of this has to be less than or equal to $60 because that is all the money she has. I hope this helps!! Please mark me brainliest!!
Answer:
[tex] 22 + 8x \le 60 [/tex]
Step-by-step explanation:
She has at most $60, so the amount she spends is less than or equal to $60.
[tex] amount~she~spends \le 60 [/tex]
The jeans cost $22.
The shirts cost $8 each, so for x shirts, she'll pay 8x.
The total amount she spends is 22 + 8x. It must be less than or equal to 60.
[tex] 22 + 8x \le 60 [/tex]

The top view of a school bus showing the arrangement of the passenger seats is shown below: which of the following is the correct way of counting the total number of passenger seats in the bus
The correct way of counting the total number of passenger seats in this bus is: option C: 5 × 12 + 6.
What is an expression?An expression refers to a mathematical equation which is used to show the relationship that exist between two or more numerical quantities.
How to calculate the total number of passenger seats?In order to determine the total number of passenger seats, we would develop an expression that multiplies the rows by the columns and then add the remaining seats as follows:
Total number = (5 × 12) + 6
Total number = 60 + 6
Total number = 66 seats.

Write the polynomial form given the leading coefficient
and the zeros of the function.
1. Leading coefficient: -1; roots: 1, 1+73, 1 - 3
someone help please
Answer:
For a polynomial of any degree, with roots x₁, x₂, ...., xₙ and a leading coefficient A, we can write it as:
p(x) = A*(x - x₁)*(x - x₂)*...*(x - xₙ)
In this case, we have:
Leading coefficient = -1
Roots : 1, 1 + 73, 1 - 3
Then the polynomial will be:
p(x) = -1*(x - 1)*(x - (1 + 73))*(x - (1 - 3))
= -1*(x - 1)*(x - 74)*(x + 2)
Now, if the roots are:
1, 1 + 73*i, 1 - 3*i
then:
p(x) = -1*(x - 1)*(x - 1 - 73*i)*(x - 1 + 3*i)

Anthony earned $131 in tips last night while working at the restaurant. If his tips consisted of $1 bills and $5 bills only and he counted 47 bills in total, then how many $5 bills did Anthony receive?
Answer:
21
Step-by-step explanation:
Let x = $1 bill
Let y = $5bill
Translating the word problem into an algebraic equation;
For the total number of bills;
[tex] x + y = 47[/tex] .........equation 1
For the total number of tips;
[tex] x + 5y = 131[/tex] ..........equation 2
*Solving the linear equation by using the substitution method*
Making x the subject in equation 1:
[tex] x = 47 - y[/tex] .......equation 3
Substituting "x" into equation 2;
[tex] (47 - y) + 5y = 131 [/tex]
Simplifying the equation, we have;
[tex] 47 + 4y = 131 [/tex]
[tex] 4y = 131 - 47 [/tex]
[tex] 4y = 84 [/tex]
[tex] y = \frac {84}{4} [/tex]
y = 21 (For the $5 bills).
Therefore, Anthony received 21 pieces of the $5 bills.
To find x;
Substituting "y" into equation 3;
[tex] x = 47 - 21[/tex]
x = 26 (For the $1 bill).
a waterslide has an angle of elevation of 20 degrees whats is the rise for a run of 2.6 m?
Answer:
Therefore, the rise will be 0.95 m
Step-by-step explanation:
As the waterslide has an angle of elevation of 20 degrees.
Ф = 20°
And we have to determine the rise for a run of 2.6 m.
All we need is to use the trigonometric ratio of tan Ф
Because
tan Ф = rise/runAs
run = 2.6 m
Ф = 20°
so
tan Ф = rise/run
tan (20) = rise/run
rise = tan (20) × 2.6
rise = 0.95 m
Therefore, the rise will be 0.95 m

The ratio of boys to girls in a class is 3:5. There are 32 students in the class. How many students are boys?
Answer:
12.
Step-by-step explanation:
to find a ratio, you must add the two numbers in the ratio, (3+5=8) and divide the total by that number (32÷8=4) once that is dine you can multiply the ratio number to find the amount (3×4=12) (5×4=20) so the ratio is 12:20, but the amount of boys is 12.

what is the y-intercept of (5,8) and (12,36)
Answer:
The y intercept is (0,-12)
Step-by-step explanation:
You use the slope formula and the slope-intercept form to find the slope m and then the y intercept b.
Answer:
(0, -12)
Step-by-step explanation:
In order to find the y-intercept of the equation y = mx + b ( where m is the slope and b is the y-intercept), we first have to find the slope. We can do this by using the two points given to us.
To find the slope:
The slope is equal to: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's plug (5,8) and (12,36) into the equation:
[tex]\frac{36 - 8}{12 - 5}[/tex]
Now let's solve for the slope:
36 -8 = 28
12 - 5 = 7
So we get: [tex]\frac{28}{7}[/tex]
Now that we've found the value of the slope, we can put it into the equation:
y = [tex]\frac{28}{7}[/tex]x + b
To find the value of b, we can input the values of one of the given points into the equation and solve for b. Let's use (5,8):
Input the values of x and y into the equation: 8 = [tex]\frac{28}{7}[/tex](5) + b
Multiple [tex]\frac{28}{7}[/tex] by 5: 8 = [tex]\frac{140}{7}[/tex] + b
Divide 140 by 7: 8 = 20 + b
Subtract 20 from both sides of the equation to isolate b:
8 - 20 = 20 - 20 + b
-12 = b
The y-intercept is (0, -12).
