Mike saves $42 a week for 7 weeks. During his 8-day vacation, he plans to spend $8.25 each day for snacks. Which expression shows how much money he will have left?
Answer:
($42 × 7) - ($8.25 × 8)
Step-by-step explanation:
Given that
Mike saves $42 a week for 7 weeks
And, his 8 day vacation, he plans to spend $8.25 each day
We need to find out the expression of how much he would have left
So,
Since the amount $42 is for a week
So for 7 weeks, it would be
= $42 × 7
And, he spends $8.25 each day,
And, for 8 days, it would be
= $8.25 × 8
So, the expression is
= ($42 × 7) - ($8.25 × 8)

Answer:
X is about 58.41 degrees
Step-by-step explanation:
For this problem, lets use sine, since we have the opposite angle from x and we have the hypotenuse.
Therefore, with the equation for sine, we would get
sin(x) = 23/27
sin(x) = 0.851
Now, since we're solving for an angle, inverse it by adding a -1 to move over the sin.
x = sin-1 23/27
Last, use a calculator to get the answer.
X is about 58.41 degrees

Indicate below whether the equation in the box is true or false 4/10=1/2
Answer:
False
Step-by-step explanation:
4/10's numerator (top number) and denominator (bottom number) can both be divided by 2. Therefore, when we do that, it will be equal to 2/5. 2/5 is not equal to 1/2. Therefore, the answer is false.

One pump can fill a tank of water in 2 hours. A second tank can fill the same tank in 3 hours. If both pumps are used together, how long will it take to fill the tank? 5/6 hours 6/5 hours 3/2 hours 2/3 hours
Answer:
6/5 hours
Step-by-step explanation:
GIVEN :-
Lets say ,
Pump A takes 2 hours to fill the tank alonePump B takes 3 hours to fill the tank aloneTO FIND :-
Time taken by both pumps to fill the tank when used togetherPROCEDURE :-
In 2 hours , Pump A fills the whole tank.
⇒ In 1 hour , Pump A will fill 1/2 part of tank. (By using Unitary method)
In 3 hours , Pump B fills the whole tank.
⇒ In 1 hour , Pump B will fill 1/3 part of tank. (By using Unitary method)
In 1 hour , when both pumps will be used together , they will fill =
(Part of tank filled by A in 1hr) + (Part of tank filled by B in 1hr)
⇒ [tex]\frac{1}{2} + \frac{1}{3}[/tex]
[tex]=> \frac{5}{6}[/tex] part of tank
5/6 part of tank will be filled by both the pumps in = 1 hour.
Using unitary method, multiplying both the sides with 6/5 -
⇒ 5/6 × 6/5 part of tank will be filled by both the pumps in = 1 × 6/5 hours
⇒ Total tank (or 1 whole tank) will be filled by both the pumps in = 6/5 hours
∴ Both the pumps will take 6/5 hour to fill the tank , when used together.

Full Answer: 11x+11*3
Find the missing term: (x+3)² = x² + 6x + _____
Answer:
9
Step-by-step explanation:
The formula for (a + b)^2 expands out to: a^2 + 2ab + b^2. In the case of this problem, a equals x and b equals 3. We can substitute to get:
(a + b)^2 = a^2 + 2ab + b^2
(x + 3)^2 = x^2 + 2(x)(3) + (3)^2
(x + 3)^2 = x^2 + 6x + 9
So, the missing term is 9.
Another way to do this is to multiply (x + 3)(x + 3) since it's the same thing:
(x + 3)(x + 3)
x^2 + 3x + 3x +9
x^2 + 6x + 9
By solving this way, you get the same answer.
Answer:
It would be 9.
Step-by-step explanation:
To do this, lets expand the equation (x+3)^2 by turning it into:
(x+3)(x+3)
Now, lets try something called the FOIL method. This is where all of the terms of the equation are multiplied in the order:
1) First
2) Outer
3) Inner
4) Last
So in (x+3)(x+3), each of the first parts of each parentheses box are x's, and x times itself equals x^2 so:
x^2 + ? + ? so far.
Next, with the Outer & Inner parts, they would be x * 3 and 3 * x. With this, you would get 3x and 3x. These can be added to get 6x, the middle part of the equation.
x^2 + 6x + ? so far.
Lastly, for the answer. Time to do the last part of each parentheses box, you would get 3 * 3, which gives you 9.
x^2 + 6x + 9.
