Answer:
9 days.
Step-by-step explanation:
We first subtract the amount already done from the total needed.
10 - 1 = 9.
Next, we take the remainder and divide it by the amount being made per day to get our final answer.
9 / 1 = 9.
The answer is 9 days.

Rondell covered a table top with 36 square tiles. Each tile measures 8 inches by 8 inches. What is the area of the table top?
Answer: 2,304 square inches
Step-by-step explanation:
if there are 36 total tiles on the table, that means there are 6 on each side.
If each side meaures 8, then one side of the table is 48, and since the tikes are square, the other side of the table will be the same. 48 x 48=2,304

Find the unknown measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.
Answer:
AB = 4.62 m∠A = 22° m∠B = 68°
Step-by-step explanation:
Tan A = 1.7/4.3 = .39534...
m∠A = arctan .39534... ≅ 22°
m∠B = 90 - 22 = 68°
AB = [tex]\sqrt{1.7^{2} + 4.3^{2} } = \sqrt{2.89 + 18.49} = \sqrt{21.38} = 4.62[/tex]
A small town has two local high schools. High School A currently has 850 students
and is projected to grow by 35 students each year. High School B currently has 700
students and is projected to grow by 60 students each year. Let A represent the
number of students in High School A int years, and let B represent the number of
students in High School B after t years. Write an equation for each situation, in terms
of t, and determine after how many years, t, the number of students in both high
schools would be the same.
Answer:
For High School A, let [tex]S_A(t)[/tex] denote the number of students after [tex]t[/tex] years. Define [tex]S_B(t)[/tex] analogously.
Then [tex]S_A(t) = 850 + 35t[/tex] and [tex]S_B(t) = 700 + 60t[/tex].
After 6 years the number of students in both high schools would be the same.
Step-by-step explanation:
For High School A, let [tex]S_A(t)[/tex] denote the number of students after [tex]t[/tex] years. Define [tex]S_B(t)[/tex] analogously.
Since we start out at 850 students at High School A and it is growing by 35 students every year, we must have that [tex]S_A(t) = 850 + 35t[/tex].
Since we start out at 700 students at High School B and it is growing by 60 students every year, we must have that [tex]S_B(t) = 700 + 60t[/tex].
Setting the two equations equal to each other, we see that [tex]850+35t=700+60t\\850-700=60t-35t\\25t=150\\t=6[/tex]
So after 6 years the number of students in both high schools would be the same.
how to I do Ratios with cross multiplying
Answer:
To cross multiply, multiply the numerator from one side with the denominator of the other side and put that product on one side of the equation. Do the same with the other numerator/denominator and put that on the other side. From there, solve for the unknown part.
So your ratio might look like this:
4/6=x/12
6x=12(4)
6x=48
x=8
So in this case 4/6 would equal 8/12.

a. -12
b. -11
C.
1.5
d. 11
Answer:
d
Step-by-step explanation:
-4+5n=18+3n
step 1 add 4 to each side
5n=22+3n
step 2 subtract each side by 3n
2n=22
step 3 divide each side by 2
n=11
The height of a male athlete testing his vertical jump can be modeled by h = − 16t ^2 + 14t. The height is h and the time is t. How many seconds is he in the air?
Answer:
0.88 (I think this is how Mrs. Futch wants it to be written)
Step-by-step explanation:
h=-16t^2+14t
(Substitute h with 0)
0=-16t^2+14t
(Factor)
0=2t(-8t+7)
2t=0 -8t+7=0
t=0 t=0.88
{0, 0.88}

and a number
5 * (-9x)
Answer:
5(9 - x)
Step-by-step explanation:
The product of 2 numbers, is just multiplication
But in this expression, we are multiplying a number by the difference of two other numbers, hence why we should group 9 - x in parentheses.

Step-by-step explanation:
The first important details are given at the start, where the beginning amount of snow is 12 inches. This is a positive number.
Then, the next sentences tell us that the snow melts at a pace of 2 inches for an x number of days.
This can be represented by -2x because the word "melts" indicates a negative value.
From this, the equation can be made :)

Bo' sister Anna is 3/4 his age minus 1 year. She is 11 years old.Write an equation to find Bo's age.
Answer: 16 years
Step-by-step explanation:
Let's Bo's age be represented by x.
Since Bo' sister Anna is 3/4 his age minus 1 year and she is 11 years old, this can be formed into an equation as:
(3/4 × x) - 1 = 11
3/4x - 1 = 11
3/4x = 11 + 1
3/4x = 12
Multiply both side by 4/3
x = 12 × 4/3
x = 16
Bo's age is 16 years
Answer:
x = 12 × 4/3

-7.2 as a mixed number.
Answer:
7 1/5
Explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
7.2=7.2/1
Multiply to remove 1 decimal places. Here, you multiply top and bottom by 10^1 = 10
7.2/1×10/10=72/10
Find the Greatest Common Factor (GCF) of 72 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
7/2÷2/10÷2=36/5
Simplify the improper fraction,
=7 1/5
In conclusion,
−7.2=−7 1/5

3x + 2 + x = x + 5
6 − x − 3 = 4(x − 2)
4x − 2 − 2x = x − 5
−(x + 3) = 2x − 6
Answer:
x=1
Step-by-step explanation:
You need to add the Numbers with an x together as if they were racist on each side so you'd have
4x+2 = x+5
Then to move them to either side you must do the opposite symbol of what they are so if their positive their now negative
4x-x=-2+5
then add them together
3x= 3
then divide the normal number with the number with the x
x=1
For the next problem you Multiply thr number that are in the paranthases by the number on the outside so
6-x-3 = 4(x-2)
6-x-3= 4x-8
then copy the steps that I told you from last problem
-9-x=4x-8
then
-9+8=x+4x
thenn
-1=5x
divide
0.2-=X
