Answer:
1979
91%
Step-by-step explanation:
Given the relation :
P = (318t + 6792) / (1.19t + 107.36)
P = % of household with PC
t = years since 2000
1.) We need to find t, when P = 85%
P = 0.85
0.85 = (318t + 6792) / (1.19t + 107.36)
0.85(1.19t + 107.36) = (318t + 6792)
1.0115t + 91.256 = 318t + 6792
Collect like terms :
1.0115t - 318t = 6792 - 91.256
−316.9885t = 6700.744
t = 6700.744 / - 316.9885
t = - 21.138760
t = - 21 years
2000 - 21 years = 1979
Percentage who had computer in 2014
t = 2014 - 2000 = 14
P = (318(14) + 6792) / (1.19(14)+ 107.36)
P = (4452 + 6792) / (16.66 + 107.36)
P = 11244 / 124.02
P = 90.6627
P = approximately 91%

can someone help me really please
Answer:
26
Step-by-step explanation:
Let x represent the missing number
[tex] 8\frac{11}{15} = 7\frac{x}{15} [/tex]
Convert both fractions to improper fractions
[tex] \frac{131}{15} = \frac{105 + x}{15} [/tex]
Cross multiply
[tex] 15(105 + x) = 15(131) [/tex]
[tex] 1,575 + 15x = 1,965 [/tex]
Subtract both sides by 1,575
[tex] 15x = 1,965 - 1,575 [/tex]
[tex] 15x = 390 [/tex]
Divide both sides by 15
[tex] x = \frac{390}{15} [/tex]
x = 26

Solve for x if ab ≠ 2c
[tex]x = \frac{ac + b}{2c - ab} [/tex]
Refer to the attachment for step by step explaination.
Answer:
[tex]x=\frac{b+ax}{2c-ba}[/tex]
Step-by-step explanation:
When given the following expression, one is asked to solve for (x):
[tex]\frac{2x-a}{b}=\frac{ax+1}{c}[/tex]
Use cross products to rid the variable in the denominator,
[tex]c(2x-a)=b(ax+1)[/tex]
Simplify, distribute, multiply every term in the parenthesis by the term outside of it,
[tex]2xc-ac=bax+b[/tex]
Inverse operations, collect all terms with variable (x) on one side of the equation:
[tex]2xc-ac = bax + b\\\\2xc - bax = b + ac[/tex]
Factor, remove a like term that exists in both of these expressions,
[tex]x(2c-ba)=b+ax[/tex]
Inverse operations,
[tex]x=\frac{b+ax}{2c-ba}[/tex]

Reese has a greenhouse and is growing daisies. The table shows the average number of sunflowers that bloomed over four months:
Month 1 2 3 4
Daisies 10 13.1 16.2 19.3
Did the number of daisies increase linearly or exponentially?
Linearly, because the table shows a constant percentage increase in daisies each month
Exponentially, because the table shows that the daisies increased by the same amount each month
Linearly, because the table shows that the daisies increased by the same amount each month
Exponentially, because the table shows a constant percentage increase in daisies each month
Answer:
linearly because the table shows that the daisies increased by the same amount each month
Step-by-step explanation:
Answer:
Linearly, because the table shows that the daisies increased by the same amount each month
Step-by-step explanation:
Take the second term and subtract the first term for the output
13.1 -10 = 3.1
Do the same for the third and the second
16.2 -13.1 = 3.1
And the fourth and third
193. -16.2 = 3.1
This is a linear increase since we add the same amount each time

To solve this problem I multiplied $9.50 x 168 to figure out how much it would cost to feed the lambs. Unfortunately my answer, $1596, was incorrect. How would I solve this type of problem?
===========================================================
Explanation:
That calculation you wrote out would only apply if each lamb ate 1 full bale of alfalfa.
Instead, each lamb eats 1/8 of a bale. So you'll divide the 1596 value by 8 to get 1596/8 = 199.50
This is the same as saying (1/8)*1596 = 0.125*1596 = 199.50
---------------------
Or we can think of it like this
1 day = 1/8 bale of alfalfa
168*(1 day) = 168*(1/8 bale of alfalfa)
168 days = 21 bales of alfalfa
This says that one lamb will eat 21 bales of alfalfa over the course of 168 days
At $9.50 per bale, the total cost for one lamb is 9.50*21 = 199.50 dollars
This cost applies to one lamb only. So if you had say 3 lambs overall, then you'd multiply that by 3.
Travis has hired Charlie and Dora to plant flowers . Dora can plant 150 flowers in the same time it takes Charlie to plant 120 flowers , which can be shown using the following relationship where d and c are the respective rates at which Dora and Charlie can plant flowers :
150 =120
——. ——
d. c
Also , Dora can plant 18 flowers more per day than Charlie
How many flowers can Charlie plant per day ?
Answer:
21 flowers
Step-by-step explanation:
because if dora can plant 18 plants then Charlie can plant 21 flowers

OPTION D is the correct answer
Perimeter of 30 ft in an area of 14 ft what is the length and the width
Answer:
14 and 1
Explanation:
14 + 14 + 1 + 1 = 30
14 x 1 = 14
The perimeter is the sum of all 4 sides. Divide the perimeter in half fo the some of one length and one width:
Length + width = 15
Area is length x width
Find 2 numbers that when added equal 15 but when multiplied equal 14
15 + 0 = 15, 15 x 0 = 0
14 + 1 = 15, 14 x 1 = 14
The answer is 14 ft long by 1 ft wide

Whats 5x=234 please answer i will brainliest if i can
Answer:
x = 46.8
Step-by-step explanation:
I assume you are trying to find the value of x.
[tex]5x=234.[/tex]
To find x, divide the answer by the coefficient. The quotient is the value of 'x.'
[tex]234/5=46.8[/tex]
Therefore, 46.8 is the value of x.
Remember: Whenever you see a coefficient and a variable together—5x, 7y, 3t—this means to multiply them.
uh hi i need help on this
Answer:
Angle 2 = 124 degrees
Step-by-step explanation:
Angles 1 and 2 are corresponding angles since the two lines are parallel.
We can put both numbers into an equation.
3x + 25 = 2x + 58
Subtract both sides by 2x which will give:
x + 25 = 58
Now, we can solve for x, which is:
x = 58-25 = 33
Put back x = 33 into angle 2.
Hence, angle 2 is 2*33 + 58 = 124
Answer:
m∠2 = 124 degrees
Step-by-step explanation:
By the definition of "Same Side Corresponding Angles" the 2 angles given are congruent to each other, therefore we can say;
3x + 25 = 2x + 58
x + 25 = 58
x = 58 - 25
x = 33
Now that we have x = 33, we can substitute 33 in for x, in equation given for angle 2 to find it's measure;
∠2 = 2(33) + 58
∠2 = 66 + 58
∠2 = 124
Therefore m∠2 = 124 degrees.
Hope this helps!
1. Write an equation to determine the height, h, of the building.
Answer: 5^2 +h^2 = 102
2. To the nearest tenth, determine the height of the
building.
Answer:
8.7 m
Step-by-step explanation:
Hi there!
[tex]5^2+h^2=10^2[/tex]
To find the height of the building, we need to isolate h on one side of the equal sign. We will do this by performing inverse operations to both sides (ex. the inverse of addition is subtraction, the inverse of multiplication is division, etc.)
Firstly, we can simplify both sides by squaring 5 and 10:
[tex]25+h^2=100[/tex]
Now subtract both sides by 25 to cancel it out on the left side and isolate h²:
[tex]25+h^2-25=100-25\\h^2=75[/tex]
Now, take the square root of both sides to isolate h:
[tex]\sqrt{h^2} =\sqrt{75} \\h=8.7[/tex]
Therefore, the height of the building is 8.7 m when rounded to the nearest tenth.
