Answer:
3:7
Step-by-step explanation:
To simplify the ratio 30:70, we find the greatest common divisor of 30 and 70, and then we divide 30 and 70 by the greatest common divisor. The greatest common divisor that you can use to simplify 30:70 is 10. This means the answer to ratio 30:70 simplified is: 3:7.

solve by substitution y=3x+5 and y=x+1
Answer:
x= -2 y= -1
Step-by-step explanation:
To solve by Substitution you would make this equation equal to each other x+1=3x+5 from there you would solve for x subtract x on both sides. and subtracting 5 from both sides 2x= -4 then divide by 2 to get x by itself x=-2 since we now found what the value of x is you can now plug in x into one of the origunal equations and get your answer for y which is y=-1

Step-by-step explanation:
angle A and angle B are complementary angles. If m angle A = (6x – 8)° and m
angle B = (5x + 21)°, then find the measure of angle B.
Answer: B = 56 degrees
Step-by-step explanation: Complementary angles add up 90 degrees. So we will set both of the equations equal to 90 degrees and then solve from there.
6x+8+5x+21=90
1. Simplify 5x + 6x and 21 - 8
11x+13=90
2. Subtract 13 from both sides.
11x=90-13
3. Simplify 90-13 to 77.
11x=77
4. Divide both sides by 11.
x = 77/11
5. Simplify 77/11 to 7
x=7
Now we have to take the value of x and substitute it back into B = (5x+21)
1. Substitute
B = (5(7)+21)
B = 35 +21
B = 56

Which of the following points lies on the graph of y=x^2-5?
Answer:
(-2,-1)
Step-by-step explanation:
The point (-2, -1) lies on the graph of y=x²-5
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given function is y=x²-5
A relation is a function if it has only one y-value for each x-value.
We have to find the points which lies on the graph of y=x²-5
The graph is a parabola which has vertex of (0, -5)
Let us find few points of function
When x=-2, y=-1
When x=0, y=-5
when x=1, y=-4
when x=2, y=-1
when x=3, y=4
when x=4, y=11
when x=5, y=20
Hence, the point (-2, -1) lies on the graph of y=x²-5

First, follow the first step in PEMDAS so you would do the parenthesis first followed by exponents, multiplication, division, addition, then subtraction
Step-by-step explanation:
6 + 8 ÷ 4 (4*5)^2
6 + 8 ÷ 4 + 20^2
6 + 8 ÷ 4 + 400

There were 680 gallons of water ALREADY in a 1600-gallon pool. Water is being pumped into the pool at the rate of 320 gallons per hour. Let x represents the number of hours. Find how many hours it will take to fill the pool.
Answer:
2 7/8 hours
Step-by-step explanation:
Answer:
2hrs 12 mins
Step-by-step explanation:
5hrs = 5x = 1600 question asks us to find 680
2 1/2x + 680-640 =-x + 2.8hrs
2x + 40 = x + 2.8hrs
2x + 40 = 680
Then use the 2.8 to convert into hrs : minutes ie) 0.8 x 60
0.8 * 60 = 48 minutes
Then go back to x + 2.8hrs = x + 2hrs 48mins
2x + 48 = 60
2x + 48 = 60
2x+ 60 - 48
x = 2:12 hours
Find the area of trapezoids
Answer:
Area is 10.5
Step-by-step explanation:
We can use the trapezoid formula of
[tex]A = \frac{a+b}{2}h[/tex]
A = (2 + 5) / 2 * 3 = 3.5 * 3 = 10.5
or break it into a rectangle and a triangle (natural split by y axis).
A = 2 * 3 + 3 * 3 / 2 = 6 + 9 / 2 = 6 + 4.5 = 10.5
Answer:
10.5 units²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = OS = 3 , b₁ = OC = 5 , b₂ = SK = 2 , then
A = [tex]\frac{1}{2}[/tex] × 3 × (5 + 2) = 1.5 × 7 = 10.5 units²

total weekly payroll?
B
A 7. (20 − n)
(7 • 20).
с 20 · (n + 7)
D (n + 20) • 7
Answer:
B if there is an N at the end or beginning of it, Not sure if it cut off or not.
Step-by-step explanation:
Well you would need to do 20(7) to get 140, then multiply that to N. I would say B because I'm assuming you're missing out on some part of it, if it is N at the beginning or end then it is B.

The speed of a truck, s, must be no less than 34 miles per hour.
Answer:
s = ≥34
Step-by-step explanation:
The speed of the truck, s, must be no less than 34 miles per hour
is s ≥ 34.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, The speed of a truck, s, must be no less than 34 miles per hour.
Therefore, The speed of the truck must be greater than or equal to 34 miles per hour.
So, The inequality that represents this context is,
s ≥ 34.

Write an expression, in its simplest form, for the volume of this cuboid
Answer:
[tex]V=10x^2+35x+15[/tex]
Step-by-step explanation:
Given that,
Length = (2x+1)
Width = (x+3)
Height = 5
We need to find an expression for the volume of this cuboid . The formula for the volume of cuboid is given by :
[tex]V=lbh[/tex]
So,
[tex]V=(2x+1)\times (x+3)\times 5\\\\=(2x+1)\times (5x+15)\\\\=10x^2+30x+5x+15\\\\=10x^2+35x+15[/tex]
So, the volume of this cuboid is equal to [tex]10x^2+35x+15[/tex].
Since multiplication is implied algebra we often don't need to actually write the times symbol ‘×'. Re-write this algebraic equation without the times symbol. a × b = 4 × c
Answer:
ab=4c
Step-by-step explanation:
Since a and b are being multiplied, we can just right ab. Since 4 and c are being multiplied, we ca just right 4c.
Answer:
ab=4c
Step-by-step explanation:
Basically, if you see any variables that are together like that or numbers side by side with letters, it means it's just being multiplied! This doesn't however, work with numbers next to numbers. So for example:
Say you have a x b = 5 x 5c
It would be ab = 5 x 5c Because only letters get put next to each other. That's really the only way I know how to explain it. Have a great day and good luck!
