The equation 9(u – 2) + 1.5u = 8.25 models the total miles Michael traveled one afternoon while sledding, where u equals the number of hours walking up a hill and (u – 2) equals the number of hours sledding down the hill. Which is the value of u?
u = 0.25
u = 0.75
u = 1.1
u = 2.5
Answer:
D: U= 2.5
Step-by-step explanation:
The value of u in the equation is approximately 2.5
Algebraic equation 9(u – 2) + 1.5u = 8.25
where
(u – 2) = the number of hours sledding down the hill
The value of u can be found as follows:
9(u – 2) + 1.5u = 8.25
9u - 18 + 1.5u = 8.25
combine like terms
9u + 1.5u - 18 = 8.28
add 18 to both sides
10.5u = 8.28 + 18
10.5u = 26.28
divide both sides by 10.5
u = 26.28 / 10.5
u = 2.50285714286
u = 2.5

Answer:
y = 43, z = 16
Step-by-step explanation:
congruent essentially means they're the same. If you mentally map one triangle onto the other, you'll see that 43, the hypotenuse, lines up with y, and 16 lines up with z.
What is the slope between the points (2, 3) and (-1, 12)
Answer:
[tex] \huge \boxed {slope = - 3}[/tex]
Step-by-step explanation:
[tex]m = \frac{rise}{run} [/tex]
The slope is the change of y over the change of x.
[tex]m = \frac{12 - 3}{ - 1 - 2} \\ m = \frac{9}{ - 3} \\ m = - \frac{9}{3} \\ m = - 3[/tex]
Therefore, the slope is -3.

A circle has a radius of 4 feet. What is the radius of a bigger circle if the scale factor of the smaller to bigger is 4:9
Answer:
9 feets
Step-by-step explanation:
From the question, we have our scale factor as:
4:9 = 4/9
Smaller circle /Bigger circle = 4/9
A circle has a radius of 4 feet. What is the radius of a bigger circle?
Let the radius of the bigger circle = x
This is calculated as:
4/9 = 4/x
Cross Multiply
4x = 9 × 4
x = 36/4
x = 9 feet
Therefore, the radius of the bigger circle is 9 feet

16/15
[tex]1 \frac{1}{15} [/tex]
20/17
[tex]1 \frac{3}{17} [/tex]
Answer:
Step-by-step explanation:
1. When changing from improper fractions to mixed fractions, you have to divide the denomenator by the numerator and that is 7÷6 which should give you 1 remainder 1. Therefore ypur mixed fraction is 1 whole number 1/6.
2. 20/17 = 20 dividing 17 (20÷17)
Which is 1 whole number 3/17
3. Now the third too is 16/15 which is 16 dividing 15 (16÷15).
Therefore your answer is 1 whole number 1/15.
But in order to be sure of your answers, you will have to multiple the denomenator by the whole number plus the numerator.
Solve the following equation:
2(3x + 10) - 8x = 52
Answer: x=−16
Step-by-step explanation: 2(3x+10)−8x=52
(2)(3x)+(2)(10)+−8x=52
6x+20+−8x=52
(6x+−8x)+(20)=52
−2x+20−20=52−20
−2x/-2 = 32/-2
x=−16

help please how do i do this
Answer:
m<A = 39
Step-by-step explanation:
1. Approach
To solve this problem, one first has to find the value of "x", then one will substitute "x" back into the equation given for the value of m<A, to solve for m<A. In order to solve this problem, one has to know that the sum of angle measures in a triangle will always equal 180.
2. Solving for "x"
The sum of angle measure in a triangle will always equal 180 degrees, hence one can set up an equation,
m<A + m<B + m<C = 180
Substitute,
(10x - 1) + (18x + 2) + (15x + 7) = 180
Simplify,
43x + 8 = 180
Inverse operations,
43x + 8 = 180
-8 -8
43x = 172
/43 /43
x = 4
3. Solve for m<A
Now all one has to do is substitute the value of "x" back in to solve for m<A
10x - 1
x = 4
10(4) - 1
40 - 1

Advertisers want to create "awareness," which is whether a consumer even knows about a business. If your business starts with 3% awareness and grows awareness by 5% per week (compounded), how long will it take to reach 75% awareness?
Answer: 66 weeks
Step-by-step explanation:
It will take approximately 3 weeks for the business to reach 75% awareness.
What is compound growth?The compound annual growth rate (CAGR) is the annualized average rate of revenue growth between two given years, assuming growth takes place at an exponentially compounded rate.
here, we have,
To solve this problem, we can use the formula for compound growth:
E = B x (1 + R)^T
where E is the ending value (75% awareness in this case),
B is the beginning value (3% awareness),
R is the rate of growth (5%),
and T is the amount of time.
We can rearrange the formula to solve for T:
T = log(E/B) / log(1+R).
Plugging in the values from the problem, we get:
T = log(75/3) / log(1+5)
Calculating this out, we get:
T = 3.49 / 1.61
This simplifies to T = 2.16.
Since T represents the amount of time, we can round this up to 3 weeks. Therefore, it will take approximately 3 weeks for the business to reach 75% awareness.
