Answer:
Step-by-step explanation:
Let
'x' the price of the meal
15% of x or 0.15x is the tip
x + 0.15x = 20.70
1.15x = 20.70 divide both sides by 1.15
x = 20.70/1.15
x = $18
0.15*18 = $2.70
The price of the meal without the tip is $18.
The tip was $2.70.
3/4 (x-12) = 12
solve for x

HAVE A GREAT DAY!
The arctic tern flies from the Arctic to the Antarctic and back every year, a total distance of 22,000 miles! In late summer, the terns start their migration south, and it takes about 3 months to go the 11,000 miles. What is the average velocity, in miles per day, that these birds travel?
Answer:
The birds travel at an average velocity of 122.2 miles per day
Step-by-step explanation:
The arctic terns fly a total distance of 22,000 miles in their yearly migration from the Arctic to the Antarctic and back again.
The average speed is the ratio between the total distance traveled by the time they took to travel.
Assume we take an average month of 30 days, then the time the arctic terns take to travel the 11,000 miles back is 30*3= 90 days.
The average velocity is
[tex]\displaystyle v=\frac{11,000}{90}=122.2[/tex]
v=122.2 miles/day
The birds travel at an average velocity of 122.2 miles per day
Answer:
The artic tern flies 11000 miles about 3 months at an average velocity of 122.222 miles per day.

How is the interest rate on a payday loan calculated?
a.
loan amount divided by total fees
b.
total fees divided by loan amount
c.
total fees divided by days of loan
d.
APR divided by 365
Answer:
b. total fees divided by loan amount
Step-by-step explanation:
The interest rate on a payday loan is usually calculated by dividing the total fees accrued in the loan repayment calculation by the exact loan amount.
Doing this will result in determining the interest rate used in a loan and it’s usually important to ensure accountability and also making sure the exact rate contained in the Loan application agreement Is the same as what is used later on.

$600 7) Nika puts 42 beads in each necklace. Which is the best way to use rounding numbers to estimate the number of beads Nika needs for 2 necklaces? 25 x 45 O 30 x 30 O 20 x 40 O 30 x 40
Answer:
20 X 40 = 800 (split into 2 fourths) = 40
Step-by-step explanation
20 x 40 = 800;
For 2 necklaces she can split 800 into fourths.
800 - 40 = 80. (1 fourth)
80 - 40 = 40 (2 fourths)
40 - 40 = 0 (3 fourths)
She could split 800 into 2 fourths to get a number more than 0 and less then 42.
The best estimate of rounding 42 is 40. Because 40 is closer to 42.
what is the estimate product of 33 and 76

Assume there are 11 voting districts in the county. Polly Tician is running for office. She figures she must win at least 7 of the districts to win the election. If she has an equal chance of 60% to win any one district, what are her chances of winning the election?
Answer:
53.3%
Step-by-step explanation:
Here we will use binomial probability:
P = nCr pʳ qⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1−p).
In this case, n = 11, r ≥ 7, p = 0.6, and q = 0.4.
P = ₁₁C₇ (0.6)⁷ (0.4)⁴ + ₁₁C₈ (0.6)⁸ (0.4)³ + ₁₁C₉ (0.6)⁹ (0.4)² + ₁₁C₁₀ (0.6)¹⁰ (0.4)¹ + ₁₁C₁₁ (0.6)¹¹ (0.4)⁰
P = 0.236 + 0.177 + 0.089 + 0.027 + 0.004
P = 0.533

Answer:
$1017.19
Step-by-step explanation:
First find the fraction of how much of Paulo's money is spent on his rent and car. Add 1/4 and 1/8, which is 3/8 because 1/4 = 2/8. Then multiply 3/8 by Paulo's monthly spending, which is $2712.50. Multiplying those numbers will get you $1017.1875. which you have to round up to $1017.19 because you can't spend three quarters of a cent.
Answer:
Asumming that you are rounding to the nearest hundreth:
1,017.19
Step-by-step explanation:
Find [tex]\frac{1}{8}[/tex] of 2,712.5 to find how much money Paulo spends on his car.
[tex]\frac{1}{8}[/tex] = .125
Multiply 2,712.5 by .125
2,712.5 × .125 = 339.0625 ≈ 339.06
Now, find [tex]\frac{1}{4}[/tex] of 2,712.5 to find how much paulo spends on his rent.
[tex]\frac{1}{4}[/tex] = .25
Multiply 2,712.5 by .25
2,712.5 × .25 = 678.125 ≈ 678.13
Add the two values together to get your answer
339.09 +
678.13
----------
1,017.19
(Another way to dolve this problem would be to find [tex]\frac{5}{8}[/tex] of 2,712.5 and subtract it from the origional value, 2,712.5)

If f(x) = 16x – 30 and g(x) = 14x – 6, for which value of x does (f – g)(x) = 0? –18 –12 12 18
Answer:
Option 3: 12 is the correct answer.
Step-by-step explanation:
Given functions are:
[tex]f(x) = 16x-30\\g(x) = 14x-6[/tex]
In order to find the value of x on which (f-g)(x) will be zero, first of all we have to find (f-g)(x) and then equate it equal to zero to find the value of that will make (f-g)(x)
So,
[tex](f-g)(x) = f(x) - g(x)\\= (16x-30)-(14x-6)\\=16x-30-14x+6\\= 2x-24[/tex]
Now to find the value of x on which (f-g)(x) will be zero, putting (f-g)(x) = 0
[tex](f-g)(x) = 0\\2x-24 = 0[/tex]
Adding 24 on both sides
[tex]2x-24+24 = 0+24\\2x = 24[/tex]
Dividing both sides by 2
[tex]\frac{2x}{2} = \frac{24}{2}\\x = 12[/tex]
For x=12, (f-g)(x) will be zero.
Hence,
Option 3: 12 is the correct answer.

learning task 1: identify similar and dissmilar fractions . on your notebook write S if the fractions are similar and D if dissmilar 1. 2/3 and 1/3
Answer:
"S" (similar fractions)
Step-by-step explanation:
Since "similar fraction" are those with the same denominator, in our case, since 2/3 and 1/3 have both the same denominator "3", these are similar fractions.
15. Construct Arguments Maggie said that
she could add 8 to both sides of any
equation and the expressions on both sides
of the equation would still be equal. Do you
agree? Explain.
Answer:
I do not agree because if there is an equation like 7+8 the answers would not be equal. They can only be equal if you add 8 to each side of the same number. For example, 7+7 with 8 added on both sides would be equal. But Maggie says that it can be equal for any equation. Therefore, Maggie is wrong.

The sum of two numbers is 38 and the difference is 8. What are the numbers?
Answer:
Since the sum is 38, y must be 15. And indeed the difference between 23 and 15 is 8, so it's correct.
Answer:
15 & 23
Step-by-step explanation:
I used an insert and check kind of method. Basically you insert numbers and check if they work for both equations. the equations are as follow:
X + Y = 38
X - Y = 8
I inserted various combinations of numbers and we'll use one as reference.
