use the distributive property to multiply -7(-p+6)
Answer:
-7(-p+6)
Step-by-step explanation:
Answer:
-7(-p+6)
Step-by-step explanation:
Answer:
[tex]7p-42[/tex]
Why:
To use the distributive property, you multiply all things within the parantheses by the -7 (in this case). To Multiply -p and -7, remember that a negative times a negative equals a positive, so it simply results in 7p. When you multiply -7 and 6, multiply them together and you get -42. You get [tex]7p+-42[/tex], but that's not a fully simplified equation, so get rid of the addition symbol and make the 42 positive. This expression is now fully simplfied into [tex]7p-42[/tex].
P.S. Never ever add a negative in an expression. Lots of teachers like to dock your points for doing it.

If Chelsea wants to fill the pool to
15
15
inches, how many gallons of water will she use?
Chelsea will use
Answer:
33.75 gallons
Step-by-step explanation:
Determine how high the pool fills with one gallon
How high the pool fills with one gallon = 4/9 = 0.444444
The gallons needed to get the water to be 15 inches = 15 inches / 0.44 = 33.75 gallons

help meeeeee plzzzzzz asap Find the area of the shaded regions.
Area of a circle is PI x r^2
The radius of the large circle is shown as 8 m
The diameter of A is the radius of the large circle which is 8 m so the radius would be 4 m
The radius of the small circle would be 2m
Area of large circle = pi x 8^2 = 64pi = 200.96 square m
Area of middle circle = pi x 4^2 = 16pi = 50.24 square m.
Area of small circle = pi x 2^2 = 4pi = 12.56 square m.
The area of the shaded region = large - middle + small
Area = 64pi - 16pi + 4pi = p2pi square m or 200.96 -50.24 + 12.56 = 163.28 square m.

please help i need the number of visita
answer
x=28
explanation
so what would happen is you pay a fee of 22$ and then 1$ per visit and we are looking to see how many visits it take to get to 50$
what we do it put
22+x=50
x is how many visits it would take to 50$
so what we do is subtract 22 from both sides
x=50-22
x=28

Desirae made 138 cookies this week. She baked 2 more than 4 times the total she made last week. How many cookies did she bake last week?
Answer: 34 cookies baked last week
Step-by-step explanation:
138=4x-2
136=4x
34=x
Answer:
34 cookies!
Step-by-step explanation:
If we say the number of cookies that Desirae baked last week was 'x', we can make the following equation for how many she baked this week: 4x+2=138. Here are the following steps to solve for x:
4x=138-2=136
x=34
Therefore she baked 34 cookies last week.

Misha and Dontavious were asked to solve the following problem using linear programming.
A local school district can operate a large bus for $300 per day and a small bus for $200 per day. The district needs to arrange transportation for at least 360 students for a field trip and has enough chaperones to have one chaperone per bus for up to 7 buses. Each large bus can hold 60 students and each small bus can hold 45 students. What is the minimum cost for the transportation for the field trip?
Misha decided the following represented this situation:
Let x = number of large buses
Let y = number of small buses
Objective Fx: C=300x+45y
Constraints:
200+60y≥360
x+y≤7
x≥0
y≥0
Dontavious decided the following represented this situation:
Let x = number of large buses
Let y = number of small buses
Objective Fx: C=300x+200y
Constraints:
60x+45y≥360
x+y≤7
x≥0
y≥0
Decide which student set up the correct Objective function and Constraints and using that information answer the following:
a) What are the vertices for the correct feasible region?
b) What is the minimum cost for transportation for the field trip and how did you arrive at this cost?
The correct function was: Dontavious
The constraints are the number of students at least 360 and the number of buses up to 7.
Dontavious wrote the appropriate inequalities. cost is $300 for large buses and $200 for small buses. and the constraints are the number of students per bus.
a) The feasible region is where the solution spaces overlap: this creates a small triangular area with the vertices at (6, 0), (7, 0) and (3, 4).
(6, 0), (7, 0), (3, 4)
b) 3 large buses and 4 small buses would cost 3*300 + 4*200 = $1700
6 large buses and 0 small buses would cost 6*300 = $1800 dollars
The cheapest solution would be 3 large buses and 4 small buses which would cost $1700
Kathleen bought some glasses. She received a rebate of $50. Of her glasses cost $125, how much did she pay?
Answer:
You will pay $62.5 for a item with original price of $125 when discounted 50%. In this example, if you buy an item at $125 with 50% discount, you will pay 125 - 62.5 = 62.5 dollars.

Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integration.)
[tex]\frac{dy}{dx}[/tex] = 4x^1/6
Answer:
For this we can first multiply both sides by dx:
[tex]dy = 4x^{1/6}dx[/tex]
Next we can integrate both sides:
[tex]\int dy = \int 4x^{1/6}dx\\[/tex]
We can then solve both integrals to get:
[tex]y = 4(\frac{6}{7}x^{\frac{7}{6}}+C_1) = \frac{24}{7}x^{\frac{7}{6}}+C_2[/tex]
We can just say the constant is C2. So the answer is
[tex]y = \frac{24}{7}x^{\frac{7}{6}}+C_2[/tex]
We can also check this by differentiating both sides. We will ultimately get the equation we with. If I made any mistakes or misread something, please let me know.

a diameter 14cm and Surface area
is 3cm?
Answer:
Thickens (Height) = 0.068 cm
Step-by-step explanation:
Given:
Diameter of disc = 14 cm
Radius of disc = 14 / 2 = 7 cm
Surface area = 3 cm²
Find:
Thickens (Height)
Computation:
Disc is a cylinder in shape
Surface area = 2πrh
3 = 2(22/7)(h)(7)
3 = 44(h)
Thickens (Height) = 0.068 cm
