in this case the slope is one and y intercept is four
Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation
A. Y-68=-5(x-14) B. Y+68=5(x+14) C. Y+68=-5(x-14) D. Y+68=5(x-14)
Answer:
A. Y-68=-5(x-14)
Step-by-step explanation:
Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation
We find the equation using the point slope equation of a line. This is given as:
y - y1 = m(x-x1)
The slope intercept form will be
y = -5x + b
since the amount decreases by $5 per day...
Our slope is -5 so m=-5
We have a point (x1,y1) = (14, 68)
Hence, we have:
y-68 = -5(x-14)
Option A is correct
An hour befor show time,only 155 people are seated for rockfest.According to ticket sales 95% of the people have yet to arrive
Question:
An hour before show time, only 155 people are seated for rockfest. According to the ticket sales, 95% of the people have yet to arrive. How many tickets were sold?
Answer:
3100 tickets
Step-by-step explanation:
Given
[tex]p = 95\%[/tex] --- Yet to arrive
[tex]Seated = 155[/tex]
Required
Determine the total number of people
If 95% are yet to arrive, then 5% have arrived (i.e. 100% - 95%)
So, the total number of people is calculated as:
[tex]5\% * x = 155[/tex]
Where x represents the total number of tickets
Make x the subject
[tex]x = \frac{155}{5\%}[/tex]
[tex]x = \frac{155}{0.05}[/tex]
[tex]x = 3100[/tex]

Step-by-step explanation:)
You buy a new car and it depreciates 6.2% per year in value. If the value of the car can be modeled by V(t)=45,000⋅bt, what would be the value of b?
Answer:
b = 0.938
Step-by-step explanation:
Value of the car can be modeled by the function,
V(t) = [tex]45000(b)^t[/tex]
Since, formula for the depreciation is modeled by,
V(t) = [tex]V_0(1-\frac{r}{100})^t[/tex]
Here, V(t) = Final value of the car after t years
V(0) = Initial value of the car
r = rate of depreciation
t = Time (in years)
By comparing both the functions which are similar,
[tex]1-\frac{r}{100}=b[/tex]
[tex]1-\frac{6.2}{100}=b[/tex]
b = 1 - 0.062
b = 0.938

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. LaTeX: \frac{3}{4}3 4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? Enter your number as a mixed number. (no decimals)
Answer:
3 29/40 kg
Step-by-step explanation:
An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms. LaTeX: \frac{3}{4}3 4 of this weight is metal, and the rest is wood. How much does the wood part of the sculpture weigh? Enter your number as a mixed number. (no decimals)
Step 1
We find the fraction of the sculpture that is wood
Let the Fraction of the sculpture = 1
Fraction of the sculpture that is metal = 3/4
Fraction of the sculpture that is wood =
1 - 3/4
= 1/4
Step 2
How much does the wood part of the sculpture weigh? Enter your number as a mixed number. (no decimals)
This is calculated as:
Weight of the total sculpture × Fraction of the sculpture that is wood
= 14.9 kg × 1/4
= 3 29/40 kg
what does 10 = 4y equal to
Answer:
Step-by-step explanation:
Simplifying
10 = 4y
Solving
10 = 4y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-4y' to each side of the equation.
10 + -4y = 4y + -4y
Combine like terms: 4y + -4y = 0
10 + -4y = 0
Add '-10' to each side of the equation.
10 + -10 + -4y = 0 + -10
Combine like terms: 10 + -10 = 0
0 + -4y = 0 + -10
-4y = 0 + -10
Combine like terms: 0 + -10 = -10
-4y = -10
Divide each side by '-4'.
y = 2.5
Simplifying
y = 2.5

Is 12:20 , 30:50 , 75:125 equivalent
Answer:
Yes
Step-by-step explanation:
All these ratios are equivalent, because if you divide 12/20, 30/50, and 75/125 you will get .6 for each answer.
This means that the unit rate for each of the ratios is the same, and that all of them are equivalent.
Hope this helps!
