Nate deposited $3 into a savings account. He then saves $2 per week. write a linear function for this situation where x = the number of weeks and y = the total amount in the account!
Answers
Answer:
y=2x+3
Step-by-step explanation:
y=mx+b
Answer:
y=$3 + $2x.
Step-by-step explanation:
y=3+2x. Make a table, at week 1 Nate has $2 + the $3 he started with. At week 2, Nate has $4 plus the $3 he started with. And so on. Plug the number of weeks in for x and solve for y for the total at any number of weeks given.

Numbers Write the mixed number as a fraction.
Answers
As you may have noticed, to transform an improper fraction into a mixed number, you must divide the numerator by the denominator. The quotient will be the integer part of the number, and the remainder will be the numerator of the remaining fraction, which will have the same denominator as the original.
If a speedometer's absolute error is 1 mph and it measures a speed of 52 mph, what is the relative error of this measurement expressed as a percentage? (Round to the nearest tenth of a percent if necessary.
Answers
Relative error = absolute error / measured speed
Relative error = 1/52 = 0.01923
Percent = 0.01923 x 100 = 1.923%
Rounded to nearest tenth = 1.9%
Which is the volume of the solid? The solid is made up of 2 cuboids. First cuboid has length as 4 unit cubes, height as 1 unit cubes and width as 2 unit cubes. Second cuboid has length as 1 unit cube, height as 3 unit cubes and width as 2 unit cubes.
A. 14 cubic units
B. 16 cubic units
C. 21 cubic units
D. 35 cubic units
Answers
Answer:
14 cubic units
Step-by-step explanation:
The Formula for Volume is
V = L x W x H
Since there are 2, you need to add the two totals together.
Cubic one:
4 x 1 x 2 = 8 (it also doesn't matter what order you put your numbers in, you will still get the same outcome. Its called the commutative property of multiplication)
Cubic Two:
1 x 3 x 2 = 6
Now just add the totals together:
6 + 8 = 14
Here, we have to find the volume of the solid which is made up of two cuboid. We know that the volume of cuboid is given by:
V = l × w × hThe volume of the solid will be equal to the sum of volume of given two cuboid
For 1st cuboid :
l = 4 unit h = 1 unit w = 2 unitTherefore, Volume:
➝ V = l × w × h
➝ V = 4 × 2 × 1
➝ V = 8 unit³
For 2nd cuboid:
l = 1 unitw = 2 unitsh = 3 unitsTherefore, Volume:
➝ V = l × w × h
➝ V = 1 × 2 × 3
➝ V = 6 unit ³
Now, Volume of solid :
ㅤㅤㅤ➙ sum of V of cuboid
ㅤㅤㅤ➙ 8 + 6
ㅤㅤㅤ➙ 14 unit ³

Anthony bought a Bulls jersey that was originally priced $80 but was on sale for a discount of 50% off. What was the sale price of the jersey
Answers
Answer:
40 dollar
Step-by-step explanation:
half of 80 is 40
Answer:
40$
Step-by-step explanation:
sale price(S.P.)=discount% of M.P.(marked price)
S.P.=50% of 80$
S.P=50/100*80$
Hence,S.P.(selling price)=0.5*80$=40$

Each week Raisa earns $5.25 for doing chores. After saving money for 12 weeks, Raisa spends $13.45. How much money does Raisa have left?
Answers
Answer:
$49.55
Step-by-step explanation:
She earns $5.25 every week for 12 weeks, so we multiply her weekly income by 12.
$5.25 * 12 = $63.00
Then she spends $13.45, so we deduct that from her earnings.
$63.00 - $5.25 = $49.55
That shows us that she has $49.55 left.

3/4 of a number is greater than 3/16 of the same number by 81. What is 1/2 of the number?
Answers
Answer:
72
Step-by-step explanation:
The given word description can be translated to math symbols this way, when x represents the number:
3/4x -3/16x = 81
Multiplying by 16 gives ...
12x -3x = 1296
9x = 1296 . . . . . . simplify
We want to find the value of half the number, so we can divide this by 18 to get ...
x/2 = 1296/18 = 72
Half the number is 72.
The points (-6,r) and (2,5) lie on a line with slope -1/4. Find the missing coordinate r.
Answers
Answer:
r = 7
Step-by-step explanation:
Calculate the slope using the slope formula then equate to - [tex]\frac{1}{4}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, r ) and (x₂, y₂ ) = (2, 5 )
m = [tex]\frac{5-r}{2-(-6)}[/tex] = [tex]\frac{5-r}{2+6}[/tex] = [tex]\frac{5-r}{8}[/tex] , then
[tex]\frac{5-r}{8}[/tex] = - [tex]\frac{1}{4}[/tex] ( multiply both sides by 8 to clear the fractions )
5 - r = - 2 ( subtract 5 from both sides )
- r = - 7 ( multiply both sides by - 1 )
r = 7
Answer:
[tex]\displaystyle 7[/tex]
Step-by-step explanation:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m\\ \\ \frac{-r + 5}{6 + 2} = m \Rightarrow \frac{-r + 5}{8} \hookrightarrow -\frac{2}{8} = -\frac{1}{4} \\ \\ \boxed{7 = r}[/tex]
