Answer:
First, I would find the unit rate for people 240 5
people who bike 48 1 . Next, I would
find the number of people who like to bicycle in a group of 360 people and
assume that only people that like to bicycle would own a mountain bike:
5 360 = = 72
1
x
x , . Finally, I would write the ratio 7 mountain bikes = 18 bicyclists= bicyclists 72
x
and
solve for x to see that there should be 28 mountain bikes.
Step-by-step explanation:
Find the missing value in the table.
The answer would be 80. why? just basically add the x number by it's self and you get your answer.
like 5 +5 gets u 10 in the y axis
and 40+40 gets u 80 in the y axis.

Answer:
3(x+2)
-(2-x)
(3x-2)
Step-by-step explanation:
3x+6= 3(x+2)
= 3x+6
x-2= -(-x+2)
= x -2
15x-10 / 5 = 5(3x-2)/ 5
Cancel 5
(3x-2)
The area of a parallelogram is given by the equation x2+8x−5=0, where x is the length of the base. What is the length of this base?
Answer:
0.5826 units
Step-by-step explanation:
We are given that the area of a parallelogram is given by the equation
[tex]x^2+8x-5=0[/tex]
Where x= Length of base
We have to find the length of base
[tex]D=b^2-4ac[/tex]
We have
a=1,b=8,c=-5
Using the formula
[tex]D=8^2-4\times (-5)=84[/tex]>0
Now,
[tex]x=\frac{-b\pm \sqrt{84}}{2a}[/tex]
Using the formula
[tex]x=\frac{-8\pm \sqrt{84}}{2}[/tex]
[tex]x=\frac{-8\pm 2\sqrt{21}}{2}[/tex]
[tex]x=\frac{-8+2\sqrt{21}}{2}=-4+\sqrt{21}[/tex]
[tex]x=-4+4.5826=0.5826[/tex]
[tex]x=\frac{-8-2\sqrt{21}}{2}=-4-4.5826=-8.5826[/tex]
Length of base cannot be negative
Therefore, the length of base=0.5826 units

Carrie borrowed $800 dollars from her aunt at 8% interest per year. If she paid her a total of $448 in simple interest, how many years did it take her to pay her aunt back?
Answer:
13 years
Step-by-step explanation:
First we will have to see how much she owns her aunt:
800-448= 362
8% of 348 = 27.84
362 ÷ 27.84 = 13 years
I might be wrong but hopefully this helps :)
Find the following, giving your answers to 1 decimal place. 10 cm 8 cm 6 cm a) The volume of the cone. b) The curved surface area of the cone.
Answer:
Volume of cone = 209.44 cm²
Curved surface area of cone = 188.57 cm
Step-by-step explanation:
Given:
Height h = 8 cm
Slant height l = 10 cm
Radius r = 6 cm
Find:
Volume of cone
Curved surface area of cone
Computation:
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)π(5)²(8)
Volume of cone = 209.44 cm²
Curved surface area of cone = πrl
Curved surface area of cone = π(6)(10)
Curved surface area of cone = 188.57 cm

Drag a description to match each equation.
Additive: y is 4 more than x.
Additive: x is 4 more than y.
Multiplicative: y is 4 times x.
Multiplicative: x is 4 times y
y = 4x
y = x + 4
Given:
The descriptions and equations. The equations are
[tex]y=4x[/tex]
[tex]y=x+4[/tex]
To find:
The correct description for each equation and match them.
Solution:
We know that, "+" is used for more and "×" is used for times.
Additive: y is 4 more than x.
[tex]y=x+4[/tex]
Additive: x is 4 more than y.
[tex]x=y+4[/tex]
Multiplicative: y is 4 times x.
[tex]y=4x[/tex]
Multiplicative: x is 4 times y
[tex]x=4y[/tex]
Therefore, the correct description for the equation [tex]y=4x[/tex] is "Multiplicative: y is 4 times x " and the correct description for the equation [tex]y=x+4[/tex] is "Additive: y is 4 more than x. "

Which equation is true for the value b = 2?
2b + 24 = 30?
3b − 2 = 4
b + 4 = 8
OR 2b − 3 = 0
Which is correct
Answer:
3b - 2 = 4
Step-by-step explanation:
3(2) = 6
6 - 2 = 4
Answer:
3b − 2 = 4
Step-by-step explanation:
2b + 24 = 30
3b − 2 = 4
b + 4 = 8
2b − 3 = 0
2b + 24 = 30
2(2) + 24 = 30
4 + 24 = 30
28 ≠ 30
-----------------------------------------------------------------------------------------------------------------
3b − 2 = 4
3(2) - 2 = 4
6 - 2 = 4
4 = 4
-----------------------------------------------------------------------------------------------------------------
b + 4 = 8
(2) + 4 = 8
6 ≠ 8
-----------------------------------------------------------------------------------------------------------------
2b - 3 = 0
2(2) - 3 = 0
4 - 3 = 0
1 ≠ 0

The answer to the question is 4.
Slope is equal to rise divided by one. If you know the horizontal distance (run) in the slope, how can you find the vertical distance (rise)?
Answer:
By multiplying the run by the slope, we get the rise value
Step-by-step explanation:
Mathematically. we have
slope = rise/run
Now, given that we know the run and we have the value of the slope, how can we get the rise
To get the rise, we simply have to multiply the run by the value of the slope
Hence, multiplying the run by the value of the slope will give the value of the vertical distance which is the rise

What Julie did wrong was, she did simplify she just did it wrong. She used 4*8 which does equal 32 but 8 can't be simplified anymore than that. If she would of used 2*16 then her answer would be right.
Hope this helps!
Answer:
[tex]5 \sqrt{18} - \sqrt{32} \\ = 5 \sqrt{9 \times 2} - \sqrt{4 \times 4 \times 2} \\ = 5 \times 3 \times \sqrt{2} - 2 \times 2 \times \sqrt{2} \\ = 15 \sqrt{2} - 4 \sqrt{2} \\ = \boxed{11 \sqrt{2} }[/tex]
