Step-by-step explanation:
7m+19/2=13
7m +19 = 13 x 2
7m = 26 - 19
m = 7/7 = 1
Another way :
7m+19/2=13
7m = 26/2 - 19/2
7m = 7
m = 7/7 = 1
Both ways r correct !!

The Scenario:
The Powerball Lottery jackpot reaches 1.5 billion dollars, and Jeffrey decides to spend some money each week on lottery tickets. He puts some money in a new bank account and withdrawals the same amount once a week to try his luck at winning the jackpot. After three straight weeks of no luck, Jeffrey has $205 left in his account. After twelve total weeks, he still hasn’t won a thing and has $160 left to spend.
Karen, on the other hand, knows the odds of winning are almost impossible, and decides to start a savings account instead at the same time as Jeffrey. Karen consistently deposits $7 each week into her account, and after seven weeks has a total savings of $89. Unfortunately, Karen’s account does not earn any interest due to the extremely low interest rate.
a) Write an equation that models how much money is in Jeffrey’s account at any given week. Show all work in the space below. You can type your work, or insert a picture of hand-written work.
b) Write an equation that models how much money is in Karen’s account at any given week. Show all work in the space below. You can type your work, or insert a picture of hand-written work
c) Show algebraically when Jeffrey and Karen will have the same amount of money in their accounts. Show all steps.
d) Show algebraically when Jeffrey will run out of money, assuming he never actually wins anything. Show all steps.

An 18-feet ladder is leaning against the side of a building. The angle between the ladder and the ground is 30°.
How high up on the building, from the ground, is the top of the ladder?
9514 1404 393
Answer:
9 feet
Step-by-step explanation:
The sine relation applies.
Sin = Opposite/Hypotenuse
sin(30°) = height/(18 ft)
height = (18 ft)sin(30°) = (18 ft)(1/2)
height = 9 ft
The ladder extends 9 feet up the side of the building.

A grocery store owner buys a certain brand of crackers from a supplier at $0.95 per box. She sells it to her customers at a markup of 120%. How much does she charge for each box of crackers?
Answer:
Selling price= $1.14
Step-by-step explanation:
Giving the following information:
Purchase cost= $0.95
Mark up percentage= 120% = 1.2
Selling price= $1.14
Selling price= purchase cost * mark up percentage
Selling price= 0.95 * 1.2
Selling price= $1.14
The three squares below join together to form a right triangle. The area and the perimeter for two of the squares is shown. Find the side length of the largest square.
Answer:
YES
Step-by-step explanation:
by dividing perimeter by 4, we
get the side lengths of 12, 35 and 37.
122 + 352 = 372.
The side length of the largest square is 15 inches.
From the given figure, area of one of the square is 81 square inches and the perimeter of another square is 48 inches.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
We know that, the area of a square = a²
Here, a²=81 square inches
⇒ a=9 inches
The perimeter of square = 4s
⇒ 4s=48
⇒ s = 12 inches
In the given figure, let the hypotenuse of triangle be x
Using Pythagoras theorem, we get
Now, x²=a²+s²
⇒ x²=9²+12²
= 81+144
= 225
So, x=15 inches
Therefore, the side length of the largest square is 15 inches.

A trebuchet launches a pumpkin on a parabolic arc from a height of 47 ft at a velocity of 40 ft/s which gives the
following function equation h(t)= -16t^2 + 40t + 47. State the vocabulary term that is being described by the
following questions. Do not solve for any of the key features. questions a b c and d
a. When will the pumpkin reach the ground?
The pumpkin will reach the ground at
b. What is the maximum height the pumpkin reaches?
C. When does the pumpkin reach its maximum height?
d. What is the starting height of the pumpkin?
Answer:
a) 3.37 seconds
b) 75.85 feet
c) 1.25 seconds
d) 47 feet
Step-by-step explanation:
a) I could use kinematic equations here, but I'll use the one provided. Height as a function of time equals 0 when the pumpkin reaches the ground, so 0=(-16t^2)+40t+47 is your equation here. Solve for t. t=3.37
b) If you have a graphing calculator, just use maximum feature. If not, use the formula x=-b/2a. x=-40/-32, x=1.25.
Now, plug 1.25 in as t, and you'll get y=75.85ft
c) alreaady found in previous part
d) this is the constant in the formula, or the y-intercept, which is 47 (because there's no variable attached).
