When multiplying similar numbers raised to different exponents the exponents get added together.
The answer is : Suzy because when you multiply the exponents, you are finding the sum of the exponents.

At a baseball game, hot dogs cost $2.25 and drinks cost $1.75. The total cost, t, for h hot dogs and d drinks can be described by the equation t=2.25h+1.75d. If Costas spent $18.25 and bought 5 hot dogs, how many drinks did he buy?
Answer:
He bought 4 drinks
Step-by-step explanation:
18.25= 2.25(5)+1.75d
18.25= 11.25+ 1.75d
18.25-11.25= 7
7= 1.75d
7/1.75
4=d
Answer:
4 drinks
Step-by-step explanation:
t = 2.25h + 1.75d
T = Total Cost
H = Hotdogs
D = Drinks
We have our total cost, which is $18.25 dollars
18.25 = 2.25h + 1.75d
We know Costas bought 5 hotdogs, so replace h with 5 and multiply :
2.25(5)
==> 11.25
Now that 11.25 dollars has been made, let's see how much money we need left to fit for the drinks.
18.25 - 11.25
==> 7
We need 7 dollars worth of drinks, so divide the cost by the amount we need to have.
7 / 1.75
==> 4
Castos needs to buy 4 drinks.

Solve for X.........
Answer:
Hey there!
There is this equation, which states that the angle created by an inscribed angle is half the measure of the arc.
Thus, we can write: 60=5x-5
65=5x
x=13
Let me know if this helps :)
Answer:
x= 13
Step-by-step explanation:
Inscribed Angle =1/2 Intercepted Arc
30= 1/2 (5x-5)
Multiply each side by 2
60 = 5x-5
Add 5 to each side
65 = 5x
Divide by 5
13 =x
If x + 4 is one factor of x3 + 64, what is the other factor?
Answer:
[tex]\Huge \boxed{(x^2 - 4x + 16)}[/tex]
Step-by-step explanation:
x³ + 64
64 is a perfect cube. Rewrite 64 as 4³.
x³ + 4³
Apply sum of cubes formula:
a³ + b³ = (a + b)(a² - ab + b²)a = x
b = 4
(x + 4)(x² - (x)(4) + 4²)
(x + 4)(x² - 4x + 16)
(x² - 4x + 16) is the other factor.
what integer is greater than -5
Answer:
-4,-3,-2,-1,0,+1,+2,+3..........
Step-by-step explanation:
-4 is greater than -5.
What is Number system?A number system is defined as a system of writing to express numbers.
An integer is the number zero, a positive natural number or a negative integer with a minus sign.
We need to find the integer which is greater than -5.
When we look into the number line we get an idea that the numbers with minus values are smaller than the positive values.
The greatest number with minus sign is smaller than the smallest number with minus sign.
-4 is greater than -5.
Not only -4 but the integers -4,-3,-2, -1, 0,1,2..... are greater.
Hence, -4 is greater than -5.

solve 1/2x + 7 = x - 3
Answer: x=20
Step-by-step explanation:
1/2x + 7 =x -3 add 3 to both sides
+3 +3
1/2x + 10 = x Subtract 1/2x from both sides
-1/2x -1/2x
10 = 1/2x
x = 20
Answer:
[tex]x=20[/tex]
Step-by-step explanation:
We can solve for x by simplifying the equation until we have x isolated on one side.
[tex]\frac{1}{2}x + 7 = x-3[/tex]
Subtract 7 from both sides:
[tex]\frac{1}{2}x = x-10[/tex]
Subtract x from both sides:

Multiply both sides by -2:

24 - 4 x 2 + 4b = 20 - 16
Answer:
b = -3
Step-by-step explanation:
Solve for b:
4 b - 4 2 + 24 = 20 - 16
-4×2 = -8:
4 b + -8 + 24 = 20 - 16
Grouping like terms, 4 b - 8 + 24 = 4 b + (24 - 8):
4 b + (24 - 8) = 20 - 16
24 - 8 = 16:
4 b + 16 = 20 - 16
20 - 16 = 4:
4 b + 16 = 4
Subtract 16 from both sides:
4 b + (16 - 16) = 4 - 16
16 - 16 = 0:
4 b = 4 - 16
4 - 16 = -12:
4 b = -12
Divide both sides of 4 b = -12 by 4:
(4 b)/4 = (-12)/4
4/4 = 1:
b = (-12)/4
The gcd of -12 and 4 is 4, so (-12)/4 = (4 (-3))/(4×1) = 4/4×-3 = -3:
Answer: b = -3

Kevin mowed 12 lawns and earned a total of $60.
Which rate represents the amount of money earned per lawn?
Answer:
$5
Step-by-step explanation:
$60 earned for moving 12 lawns
Amount of money per lawn is:
$60/12= $5Answer is amount per lawn is $5
Answer:
$5
or
$5 / 1 lawn
Step-by-step explanation:
The process is quite simple - especially since you already have half of the answer. The question says money per lawn. The creator of the problem gave away a lot of the answer. They already tell us the rate. Now all ou have to do is plug the numbers in:
Money per lawn
Money / lawns (The slash is used to represent per)
What is the money? $60. So plug that in:
$60 / lawns
How many lawns? 12. Plug that in:
$60 / 12 lawns
Now, all you have to do is either simplify the fraction or divide the denominator by the numerator - whichever one you prefer. In that case, the rate can be any of the following:
$5
$5 / 1 lawn

Use the figure to the right to find the value of PT. T is the midpoint of PQ PT=7x+9 and TQ=9x-5
Answer:
58
Step-by-step explanation:
Since, T is the mid point of PQ,

The value 191.5638 rounded to the nearest hundredth is
191.564
191.5600
191.56
200
Answer:
191.56
Step-by-step explanation:
Given
191.5638
Required
Approximate
Approximating to the nearest hundredth implies that, only to digits after the decimal point is needed
This is:
191._ _
The third digit after the decimal point will approximated using the approximation rule;
Since, the third digit after the decimal point (3) is not up to 5, it'll be approximated to 0 and added to the second digit (6)
So, we have:
191.5 _
The next digit is calculated as 6 + 0 = 6
Hence, the full approximated number is 191.56
flying against the wind, a jet travels 4600 miles in 5 hours. flying with the wind, the same jet travels 4200 miles in 3 hours. what is the rate of the jet in still air and what is the rate of the wind?
Answer:
The rate of the jet in still wind is 1160 MPH and the rate of the wind is 240 MPH.
Step-by-step explanation:
Distance equals rate times time (d = rt)
Against the wind, the rate is:
4600 = r * 5
r = 4600/5 = 920 MPH
With the wind, the rate is:
4200 = r * 3
r = 4200/3 = 1400 MPH
Let W be the rate of the wind in MPH. We know that:
(rate of the jet against the wind) + (rate of the wind) = (rate of the jet with the wind ) - (rate of the wind), so:
920 + W = 1400 - W
2W = 480
W = 240 MPH
And the speed of the jet in still air would be:
1400 - 240 = 1160 MPH

Neal opened a savings account 11 years ago with a deposit of $2,335.69. The account has an interest rate of 4.3% compounded daily. How much interest has Neal earned? (3 points)
$1,412.52
$2,436.12
$1,375.75
$3,748.21
Answer: $1,412.52
Step-by-step explanation:
Formula to calculate the accumulated amount if P principal invested for t years at a rate of interest r that compounded daily is given by:-
[tex]A=P(1+\dfrac{r}{365})^{365t}[/tex]
Given: P= $2,335.69
r= 4.3%= 0.043
t= 11 years
Then,
[tex]A=2335.69(1+\dfrac{0.043}{365})^{365\times11}\\\\=2335.69(1+0.000117808219178)^{4015}\\\\=2335.69(1.000117808219178)^{4015}\\\\= 2335.69(1.6047566747)\\\\=3748.09044309\approx3748.21\\\\\Rightarrow\ A=\$3748.21[/tex]
Interest earned = A-P
= $3748.21- 2335.69.
= $1412.52
Hence, Neal earned $1,412.52 as interest.
