Josh took his girlfriend out to dinner for her birthday. Dinner was $74.96. Tax on the meal was 7.5% of the price of the meal. They left a tip that was 18% of the meal and tax. What is the total cost of the meal?
Answer:
$97.07
Step-by-step explanation:
7.5% of 74.96 is 5.62
18% of 74.96 is 13.49
74.96+5.62+13.49=97.07

What's the equation of a line that passes through (-4,-7) and (4,-1)
What's the equation of a line that passes through (-4,-7) and (4,-1)
Answer:
y=-x+3
Answer:
y = 3/4x - 4
Step-by-step explanation:
Slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (-1 - (-7)) / (4 - (-4))
= 6 / 8
= 3/4
y-intercept:
y = mx + b
use the slope above and anyone of the given points to find b. Let's use (4, -1)
(-1) = 3/4(4) + b
-1 = 12/4 + b
- 1 = 3 + b
b = -4
Equation of a line:
y = mx + b
use the m and b from above to form the equation of a line.
y = 3/4x - 4
Write the equation of the line below, in slope-intercept form.
Answer: y=3x-3
Step-by-step explanation: Formula: y=mx+b The slope is m which is 3, rise over run, and b is the y-intercept which is -3.
Answer:
y=3x+-3
Step-by-step explanation:
the slope is 3/1 which is 3.
the y intercept is the point at which theine crosses te y axis so it's-3
y=mx+b
y=3x+-3

B. 50 + 5p ≤ 85
C. 5 (50 + p) ≥ 85
D. 5 (50 + p) ≤ 85
Answer:
There ya go

If Jerome wants to have read at least 85 pages by the end of the day on Friday, then the inequality that represents the situation will be 50 + 5p≥ 85
Given that the number of pages he read each day is "p", the number of pages he will read from Monday to Friday is 5p (Monday to Friday is 5 days)If he has read 50 pages of a novel, the total number of books he has read will be 50 + 5pIf Jerome wants to have read at least 85 pages by the end of the day on Friday, then the inequality that represents the situation will be 50 + 5p≥ 85

Jim and his friends are going to the Del Mar Fair and find they have two ticket options. In one option each person could buy an admission ticket for $5 and then pay $0.25 for each ride. The other option is to buy an admission ticket for $2 and then pay $0.75 a ride. What do you think Jim should do?
Step-by-step explanation:
let the cost of the options be y
since they are two already we can model the cost as
For the first ticket option
y=5+0.25(2)
y=5+0.5
y=$5.5
For the second ticket option
y=2+0.75(2)
y=2+1.5
y=$3.5
They should go for the second ticket option since it is $2 less than the first option

2) choice A, theyre equal in length
3) Choice D, (-3,0) (-3, -3) (-1, -3)
4) Choice A, Clockwise 90- degree rotation
Step-by-step explanation:
The statements which describe A'B' is:
A'B' and AB are equal in length ⇒ (B)
Step-by-step explanation:
Let us take about reflication:
⇒ Reflections are mirror images, means the shape or the size of
the figure does not affect by reflection, think of "folding" the
graph over the y-axis or the x-axis
⇒ On a grid, you used the formula (x, y) → (-x, y) for a reflection in
the y-axis and used the formula (x, y) → (x, -y) for a reflection in
the x-axis.
In our question segment AB, where A = (1, 3) and B = (5, 3) is
reflected about the y-axis
By using the rule above
∴ A' =(-1, 3)
∴ B' = (-5,3)
∵ Reflection does not change the shape or the size of the original figure
∴ Line segment A'B' has the same length of line segment AB
The correct answer is:
A'B' and AB are equal in length
You can check your answer by finding the lengths of AB and A'B'
∵ The length of AB = 5 - 1 = 4 units
∵ The length of A'B' = -1 - (-5) = -1 + 5 = 4 units
∴ AB = A'B'
Note:
If the y-coordinates of two points are equal, then the line joining them is horizontal and its length is the difference between the x-coordinates of the two points.

Step-by-step explanation:
sam eats 1/4 of a pizza joe eats 1/2 of the remaining pizza. what part of the original pizza is left?
Answer:
1/4 of the pizza is left
If Sam eats 1/4 of the pizza, we must subtract 1/4 from 1.
1 - 1/4 = 3/4.
Now, Since Joe eats 1/2 of the pizza, we subtract 2/4, since 1/2 = 2/4.
3/14 - 2/4 = 1/4.

Answer:
a = 3.09 m/s^2
Step-by-step explanation:
v^2 = Vo^2 +2ax
v= final velocity
Vo = initial velocity
a = acceleration
x = distance
(-10.9)^2 = (-27.7)^2 + 2(a)(-105)
118.81 = 767.29 - 210a
-210a = -648.48
a = 3.09 m/s^2
[tex]( {v})^{2} - ({v(0)} \: )^{2} = 2 \times a \times ∆x[/tex]
[tex]( { - 10.9})^{2} - ({ - 27.7})^{2} = 2 \times a \times - 105 \\ [/tex]
[tex]118.81 - 767.29 = - 210 \times a[/tex]
[tex] - 648.48 = - 210 \times a[/tex]
Negatives simplified :
[tex]648.48 = 210 \times a[/tex]
Divided both sides by 210 :
[tex]a = \frac{648.48}{210} \\ [/tex]
[tex]a = 3.088 \: \: \frac{m}{ {s}^{2} } \\ [/tex]

A father is 30 years elder than his son. after 8 years he will be 4 times as old as his son. find their present ages
Father is 30 years older than the son.
After 8 years , he will be 4 times as old as his son.
Find:their present ages
Solution:Let the son's age be x and age of father be y years
⟹ Father's age = Son's age + 30
⟹ y = x + 30 -- equation (1)
Also,
Son's age after 8 years = (x + 8) years.
Father's age after 8 years = (y + 8) years.
According to the above condition,
⟹ y + 8 = 4(x + 8)
⟹ y + 8 = 4x + 32
Substitute the value of y from equation (1).
⟹ x + 30 + 8 - 32 = 4x
⟹ 6 = 4x - x
⟹ 6 = 3x
⟹ 6/3 = x
⟹ 2 = x
Substitute the value x in equation (1).
⟹ y = 2 + 30
⟹ y = 32
Therefore,
Son's present age = x = 2 years.
Father's present age = y = 30 years.
I hope it will help you.
Regards.
Answer:
→ 11(2 + y) + 11y
→ 22 + 11y + 11y = 154
→ 22y + 22 = 154
→ 22y = 154 - 22
→ 22y = 132
→ y = 132/22
→ y = 6
