Answer:
The entire race is 26.20 miles long.
Step-by-step explanation:
Given that:
Sam is 18.34 miles in the race.
This length represents the 70% of the entire length of the race.
Let,
x be the total length of the race.
70% of x = 18.34
[tex]\frac{70}{100}x=18.34\\[/tex]
0.7x = 18.34
Dividing both sides by 0.7
[tex]\frac{0.7x}{0.7}=\frac{18.34}{0.7}\\x=26.20[/tex]
Hence,
The entire race is 26.20 miles long.
What are the zeros of the function (x) = x2 – 3x+2?
Step-by-step explanation:
f(x) = x² - 3x + 2 = (x - 2)(x - 1).
When f(x) = 0, (x - 2)(x - 1) = 0.
=> x = 2 or x = 1.

Step-by-step explanation:
the other one is wrong
also have a nice day
The amount of the money to the nearest cent, would be in the account after 12 years is $133,307.18.
Calculation of the amount:Since the invested amount is $77,000
The rate of interest is 4.6% compounded continuously
And, the number of years is 12
So,
= $77,000 * (1 + 0.046/12)^48
= $133,307.18
hence, The amount of the money to the nearest cent, would be in the account after 12 years is $133,307.18.

Composition of functions~
Answer:
option D
Step-by-step explanation:
First you must find g(n) given that n is -3n:
g(-3n) = -3n - 1
Then plug that in f(n) as the new n:
f(n) 3( -3n - 1) + 5
= -9n -3 + 5
= -9n + 2
So option D

ken eats 4 plums each day. How many plums would he eat in TWO weeks?
Answer:
56 (plums)
Step-by-step explanation:
There's 7 days a week, 14 in two weeks, so if Ken eats 4 plums each day, he will eat 14 times that in two weeks.
x = 4 × 14
x = 56
Answer:
56
Step-by-step explanation:
4 plums a day, with 7 days in a week. 4*7=28 plums a week. He eats 4 plums a day for two weeks, so we multiply 28 by 2. 28*2=56.

Marie added 3 1/8 cup of all-purpose flour and 1/4 cup of whole wheat flour in the cake. She added 1/3 cup of sugar at also, how much flour she added in the cake ?
Answer:
3 [tex]\frac{3}{8}[/tex]
Step-by-step explanation:
Maria only combined two different types of flour to the cake. Therefore, in order to find the total amount of flour she added we need to add these measurements together. First, we need to find a common denominator. We do this by multiplying the numerator and denominator of the amount of whole wheat flour by 2. This would be the easiest way of giving us the same denominator as the measurement for the all-purpose flour.
[tex]\frac{1 * 2}{4 * 2}[/tex] = [tex]\frac{2}{8}[/tex]
Now that we have the same denominators we can simply add both measurements together
3 [tex]\frac{1}{8}[/tex] + [tex]\frac{2}{8}[/tex] = 3 [tex]\frac{3}{8}[/tex]
Find the sum:
The blanks r subtraction signs
Answer:
[tex]8x^2+6x-17[/tex]
Step-by-step explanation:
All that we have to do is add the 3 and 5 so it's basically like combining like terms. So the first blank is 8.
Now we add the x and the 5x which is 6x, all we're doing is adding the x's.
Now we do add the two negative 10 and 7. So what is -10 + - 7 we add them normally but we'll still have the negative in front of them. So it's -17.
1. If the point (-5, -3) is translated 4 units to the right and 3 units down, what are the coordinates
of the new point? Write the algebraic expression that represents the translation.
Answer:
(-5 + 4, -3 - 3)
Step-by-step explanation:
"4 units to the right" requires ADDING 4 to the x-coordinate of (-5, -3):
(-5 + 4, -3).
"3 units down" requires SUBTRACTING 3 from the y-coordinate:
(-5 + 4, -3 - 3), or (if simplified) (-1, -6)

Problem We can calculate EEE, the amount of euros that has the same value as DDD U.S. Dollars, using the equation E=\dfrac{17}{20}DE= 20 17 DE, equals, start fraction, 17, divided by, 20, end fraction, D. How many euros have the same value as 111 U.S. Dollar? euros How many U.S. Dollars have the same value as 111 euro? dollars
Complete Question
We can calculate EEE, the amount of euros that has the same value as DDD U.S. Dollars, using the equation
E= 17/20 D
a) How many euros have the same value as 1 U.S. Dollar? euros
b) How many U.S. Dollars have the same value as 1 euro? dollars
Answer:
a) 0.85 euros
b) 1.18 dollars
Step-by-step explanation:
The equation is given as:
E= 17/20 D
a) How many euros have the same value as 1 U.S. Dollar? euros
E = 17/20D
D = 1 dollar
Hence:
E = 17/20 × 1
E = 0.85 euros
b) How many U.S. Dollars have the same value as 1 euro? dollars
E = 17/20D
E = 1 euro
1 = 17/20D
D = 1 ÷ 17/20
D = 1 × 20/17
D = 1.1764705882 dollars
D = 1.18 dollars
