The temperature outside changed from 91°F to 49°F over a period of six days. If the temperature changed by the same amount each day, what was the daily temperature change?
Answer:
Step-by-step explanation:
The temperature change in 6 days is 91 - 49 = 42 F
So the daily change is 42/6 = 7 F.
(geometry) i would appreciate help please
Answer:
63
Step-by-step explanation:
We are taking a dilation of 3, so that means we are multiplying by 3. We multiply 3 to 21 to get 63.

The indoor climbing gym is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 12 buses with 504 students. High School B rented and filled 2 vans and 4 buses with 184 students. Every van had the same number of students in it as did the buses. Find the number of students in each van and in each bus.
High school A: 3 vans + 12 buses = 504 students
High school B: 2 vans + 4 buses = 184 students
Multiply High school B by 1.5:
High school B: 3 vans + 6 buses = 276 students
Subtract High school B from High School A:
6 buses = 228 students
Divide students by buses:
Buses = 228 / 6 = 38 students per bus
Now solve for vans using high school A:
3 vans + 12(38 students per bus) = 504 students
Simplify:
3 vans + 456 students in buses = 504 students
Subtract students in buses from both sides:
3 vans = 48
Divide both sides by 3:
Vans = 16
Answer: vans = 16 students, buses = 38 students
Which inequality represents all values of x for which the quotient below is
defined?
28(x-1) = 8x?
O A. x less than or equal to -1
B.x great than or equal to 1
O C. x> 1
O D. x<-1
You can re-write this quotient this way :
[tex]\frac{\sqrt{28(x-1)}}{\sqrt{8x^{2} }} = \sqrt{ \frac{28(x-1)}{8x^{2} } }\\[/tex]
What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))
In other word we must find x so that :
[tex]\frac{28(x-1)}{8x^{2}}\geq 0[/tex]
at the end we get
28(x-1) ≥ 0
28x - 28 ≥ 0
28x ≥ 28
x ≥ 1
So the answer is B, x ≥ 1
What is the slope of the line that passes through the points (5, 4) and (13.25, -18) ?
A.) 83/3
B) 3/8
C) −3/8
D) 8/3
Answer:
Answer: D. 8/3
Step-by-step explanation:
Formular for slope:
[ consider points (x1, y1) and (x2, y2) ]
[tex]slope = \frac{y_{2} - y _{1} }{x _{2} - x _{1} } \\ [/tex]
x1 » 5, y1 » 4
x2 » 13.25, y2 » -18
[tex]sloe = \frac{ - 18 - 4}{13.25 - 5} \\ \\ = \frac{22}{8.25} \\ \\ { \boxed{ \boxed{slope \: = \frac{8}{3} }}}[/tex]
11. Kirk's goal was to save $300 for a trip. In the first week, Kirk saved $16 from his allowance and $54 from his job. He spent $5 for lunch one day and another $2 on the bus. The second week, Kirk saved $62 and another $41, but spent $2 for the bus and $4 for lunch.
A.How much money did Kirk save in the first week? Use integers to solve.
B.How much money did Kirk save after 2 weeks?
C.If Kirk saves $150 in the third week, but spends $8, will he reach his goal of saving $300? Explain.

If the temperature outside was 73 degrees at 5:00 p.m., but it fell 19 degrees by 10:00 p.m., what is the temperature at 10:00 p.m.? Write an addition equation and solve.
please help
Answer:
73degrees-10degrees=63 degrees
Answer: 73 + (-19) = x, x = 73-19 = 54 degrees
Step-by-step explanation: Normally this would be a subtraction equation, but if you're looking for addition you can fix that by adding a negative number- which is the same as subtraction. In this case, the times have nothing to do with the equation itself.

The total amount of milk in a jug and a mug is T liters. If p ml of milk is taken from the mug to make pancakes, the amount of milk left in the mug will be half as much as that in the jug. Write an expression for the amount of milk, in liters, in the jug. Evaluate the expression if T = 2.5 and p = 250.
Answer:
Apart from PB&J and oatmeal, pancakes are the most popular (and best) breakfast meal. They’re nutritious, yummy and can be served with both salty and sweet flavors. But are they easy to make? The recipe may be simple, but there are many things we need to consider.

Round 69581.491337 to the nearest thousand.
Answer:
7000
Step-by-step explanation:
lets start with 695
9 is the thousand
you check the number next to 9
less then 4 let it rest
more than 5 let it soar
something like that lol
anyways since 5 is next to the 9 we round up from 9 to the next number which is 10
so that changes the whole number to 7000
hope this makes sense!
