Noah already has $10.50, and he earns $3 each time he runs an errand for his neighbor. Noah wants to know how many errands he needs to run to have at least $30
Answer: 7 errands
Step-by-step explanation:
Noah wants to have at least $30. He however already has $10.50.
The amount that he needs is:
= 30 - 10.50
= $19.30
For every errand he runs, he makes $3. The number of errands needed to get to $30 is:
= 19.50/3
= 6.5
= 7 errands

Find the Slope
(−1, −2) , (3, −1)
Slope is equal to the change in y over the change in x, or rise over run.
change in y
m = ---------------
change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called r ise).
y2 − y1
m = -----------
x2 − x1
Substitute in the values of x and y into the equation to find the s lope.
m = −1 − (−2) /3 − (−1)
Simplify the numerator.
Multiply −1 by −2.
m = −1 + 2 /3 − (−1)
Add −1 and 2.
m = 1/3 − (−1)
Simplify the denominator.
Multiply −1 by −1.
m = 1/3 + 1
Add 3 and 1.
m = 1/4
A score of 17 on a math test results in a mark of 68%. What score would give you a mark of 100%?
(MUST SHOW WORK)
Answer:
17/25
Step-by-step explanation:
The required total score for 100% mark is given as 25.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Let the x be the be score for 100% marks.
68% of x = 17
x = 17 / 68%
x = 25
Thus, the required total score for 100% mark is given as 25.

The area of a rectangular pool table is: x2 + 14x +40. What are the dimensions of the table?
Formula: Area = (L) (W)
A(x + 8)(x + 5)
B(x + 20)(x - 2)
C(x + 4)(x + 10)
D(x +14)(x + 40)
Answer:
the width is (x + 4) and the length is (x + 10)
Step-by-step explanation:
The area of a rectangle is given by A = L * W, where L is the length and W the width.
If we factor the given x^2 + 14x + 40, we get (x + 10)(x + 4). Thus, the width is (x + 4) and the length is (x + 10).

A baseball team batted 250 times during the season. During the season they got 120 hits, 60 strikeouts, 50 flyouts and 20 groundouts. What percent of the time that they batted did they make an out?
Answer: 52%
Step-by-step explanation:
The team batted 250 times. In that time, they got 60 strikeouts, 50 flyouts and 20 groundouts.
The total number of out they got was therefore:
= 60 + 50 + 20
= 130 outs
The percent of the time they got outs out of the total is:
= 130/250
= 52%

6338 divided by 43 with remainder
Answer:
147.395348837
Step-by-step explanation:
6338 divided by 43 gives a quotient of 147 with a remainder of 17.
When dividing 6338 by 43 with remainder, we can perform long division to find the quotient and remainder.
Start by dividing the first digit of the dividend (6) by the divisor (43). The quotient is 0 since 6 is less than 43.
Bring down the next digit of the dividend, which is 3, to the right of the 0. We now have 63.
Divide 63 by 43. The quotient is 1, as 43 goes into 63 once.
Multiply the divisor (43) by the quotient (1) and subtract the result from 63:
63 - (43 x 1) = 63 - 43 = 20
Bring down the next digit of the dividend, which is 3, to the right of the 20. We now have 203.
Divide 203 by 43. The quotient is 4, as 43 goes into 203 four times.
The final remainder is 17.
Therefore, 6338 divided by 43 gives a quotient of 147 with a remainder of 17.

Felix joined a local recreation center to play basketball the recreation center try to a $20 annual fee plus an additional $15 per month for usage of basketball courts feel like pre-pays by writing a check for $185 for how many months did Felix pay
Answer: Felix paid for 11 months.
Step-by-step explanation:
Let x = Number of months
Given: Annual fee = $ 20
charge per month = $15
Total amount = Annual fee + (charge per month) x (number of months)
[tex]\Rightarrow\ 185 = 20+15x\\\\\Rightarrow\ 165=15x\\\\\Rightarrow\ x = \dfrac{165}{15}\\\\\Rightarrow\ x =11[/tex]
Hence, Felix paid for 11 months.
Maria is bringing her sick dog, Pedro in for a series of appointments at the veterinary clinic. Her total cost over the course of treatment will be $150 for tests and medicine plus $30 per appointment "a". A) Write an equation to show the total cost, "t" she will owe. *
Answer:
t = 150 + 30a
Step-by-step explanation:
Treatment of Pedro costs = Expenditure for tests and medicines + fees given for appointments.
If number of appointments = a
Cost per appointment = $30
Cost of 'a' appointments = $30a
Therefore, equation representing the total cost 't' of the treatment will be,
t = 150 + 30a

Sewing patterns recommended buying extra fabric in case of mistakes. Darlene bought 7 yards of fabric, plus 20% extra fabric. Chris bought 4 yards of fabric plus 25% extra. Who bought more fabric. How much more?
Answer:
Darlene bought more fabric
Darlene bought 3.4 yards more
Step-by-step explanation:
Darlene = 7 yards + 20% extra
= 7 yards + (20% of 7 yards)
= 7 + (20% × 7)
= 7 + (0.2 × 7)
= 7 + 1.4
= 8.4 yards
Chris = 4 yards + 25% of 4 yards
= 4 yards + (25% of 4 yards)
= 4 + (25% × 4)
= 4 + (0.25 × 4)
= 4 + 1
= 5 yards
Darlene bought more fabric
How much more?
Darlene - Chris
= 8.4 yards - 5 yards
= 3.4 yards
Darlene bought 3.4 yards more

find the value of xin the triangle shown below
Answer:
[tex]x=80^{\circ}[/tex]
Step-by-step explanation:
Solution 1:
Recall that in an isosceles triangle, the two angles adjacent to the congruent sides are equal. Since the sum of interior angles in a triangle add up to [tex]180^{\circ}[/tex], we set up the following equation:
[tex]x+50+50=180[/tex].
Solving, we get:
[tex]x+100=80,\\x=\fbox{$80^{\circ}$}[/tex].
Solution 2:
The Law of Sines states:
[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex], for any triangle.
We can use this to set up a proportion with the information given:
[tex]\frac{\sin x}{18}=\frac{\sin 50^{\circ}}{14}[/tex].
Solving, we get:
[tex]x=\arcsin(\frac{18\cdot \sin 50^{\circ}}{14}),\\x \approx \fbox{$80^{\circ}$}[/tex].
