The perimeter of a rectangle is equal to 163 yard. The width is 8 more than twice the length. Find the length and width.
Answer:
l = 29.4 yards
w = 66.8 yards
General Formulas and Concepts:
Order of Operations: BPEMDASPerimeter of a Rectangle: P = 2w + 2lStep-by-step explanation:
Step 1: Define
P = 163 yards
w = 2l + 8
l = l
Step 2: Set up equation
P = 2w + 2l
163 = 2(2l + 8) + l
Step 3: Solve for l
Distribute 2: 163 = 4l + 16 + lCombine like terms: 163 = 5l + 16Subtract 16 on both sides: 147 = 5lDivide both sides by 5: 147/5 = lRewrite: l = 147/5Evaluate: l = 29.4 yardsStep 4: Find w
Define: w = 2l + 8Substitute: w = 2(29.4) + 8Multiply: w = 58.8 + 8Add: w = 66.8 yardsThe Mariana Trench in the Pacific Ocean is about 36,201 feet deep. The Puerto Rico Trench in the Atlantic Ocean is about 27,493 feet deep. How many feet deeper is the Mariana Trench than the Puerto Rico Trench?
Answer:
8708 feet
Step-by-step explanation:
The Mariana Trench in the Pacific Ocean is about 36,201 feet deep. The Puerto Rico Trench in the Atlantic Ocean is about 27,493 feet deep.
We need to find how many feet deeper is the Mariana Trench than the Puerto Rico Trench.
As Mariana Trench and Puerto Rico Trench is deep.
h = -27,493-(-36,201)
h = 8708 feet
So, Mariana Trench is 8708 feet deeper than Puerto Rico Trench

5. Noah and his friends are going to an amusement park. The total cost of admission for 8
students is $100, and all students share the cost equally. Noah brought $13 for his
ticket. Did he bring enough money to get into the park? Explain your reasoning.
Answer:
yes
Step-by-step explanation:
he did because 100 divided by 8 is 12.5 and that would equal $12.50
So in all he would have 50 cents left
Answer:
yes,Noah did bring enough money for the ticket.
Step-by-step explanation:
you know that it's going to 8 students and in total it's 100.You need to know how much each will need to pay so you divide 100 divided by 8.The quotient/answer to what each student will pay is 12.5. 13 dollars is more than enough to pay for the ticket so Noah did bring enough.

You have 784 grams of a radioactive kind of tellurium. If its half-life is 42 minutes, how much will be left after 126 minutes?
Answer:
98 grams
Step-by-step explanation:
The simplest way to think about this is that the half life has elapsed 3 times, so you need to take the initial mass and divide it by 2 3 times, so 784/2/2/2 or 784/8 which is 98

What value of a will yield a solution of (2,8) for the system?
y = ax
ax + y = 16
Answer:
The value of a is 4 ⇒ D
Step-by-step explanation:
In the system of equations
∵ y = ax ⇒ (1)
∵ ax + y = 16 ⇒ (2)
∵ The solution of the system is (2, 8)
∴ x = 2 and y = 8
→ To find the value of a substitute x by 2 and y by 8 in equation (1) or (2)
∵ y = ax
∵ y = 8 and x = 2
∴ 8 = a(2)
∴ 8 = 2a
→ Divide both sides by 2
∵ [tex]\frac{8}{2}[/tex] = [tex]\frac{2a}{2}[/tex]
∴ 4 = a
∴ The value of a is 4

n is an integer.
Write the values of n such that -15 < 3n<6
Answer:
(-1,-2, -3, -4)
Step-by-step explanation:
-15 < 3n <6
-15 < 3 (-1,-2, -3, -4) <6
3 • -1 = -3
3 • -2 = -6
3 • -3= - 9
3 • -4 = -12
so all these answer still make -15 the lowest value and 6 the highest value.

Which statement is true ?
Answer:
the graph of w passe through point (8,-6)
Step-by-step explanation:
When you draw a line through points (-5, 7) and (3, -1) points (8,-6) also meets the line segment at the very bottom.
Answer:
The graph of w passes through (8,-6) (FIRST ANSWER)
Step-by-step explanation:
The equation of the graph is -1x+2, therefore no other answer works
The slope is -1, not 2
The Y-intercept is (0,2), NOT the X-intercept
The zero is 2, not -1
Therefore, the only correct answer is The graph of w passes through (8,-6)
