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.

How would figure out if a equation has one answer,zero answers,or infinite. Like a equation like 3(x+9)=3x+27
what are the steps for solving
6x-1=-x+9
Answer:
x=10/7
Let's solve your equation step-by-step
6x−1=−x+9
Step 1: Add x to both sides
6x−1+x=−x+9+x
7x−1=9
Step 2: Add 1 to both sides
7x−1+1=9+1
7x=10
Step 3: Divide both sides by 7
7x/7=10/7
x=10/7
Answer:
x = 10 / 7
Step-by-step explanation:
6x - 1 = -x + 9
Add 1 to both sides of the equation.
6x - 1 = -x + 9
6x - 1 + 1 = -x + 9 + 1
Simplify
Add the numbers
6x - 1 + 1 = -x + 9 + 1
6x = -x + 9 + 1
Add the numbers
6x = -x + 9 + 1
6x = -x + 10
Add x to both sides of the equation.
6x = -x + 10
6x + x = -x + 10 + x
Simplify
Combine like terms
6x + x = -x + 10 + x
7x = -x + 10 + x
Combine like terms
7x = -x + 10 + x
7x = 10
Divide both sides of the equation by the same term
7x = 10
7x/7 = 10/7
Simplify
Cancel terms that are in both the numerator and denominator.
7x/7 = 10/7
x = 10/7
Solution
x = 10/7

The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2,200 people enter the fair and $5,050 is collected. How many children and how many adults attended?
Given :
The admission fee at a small fair is $1.50 for children and $4.00 for adults.
On a certain day, 2,200 people enter the fair and $5,050 is collected.
To Find :
How many children and how many adults attended.
Solution :
Let, number of children and adults attended are c and a.
So, c + a = 2200 ....1)
Now, fair collected is given by :
1.5c + 4a = 5050 ....2)
Putting value of a from equation 1) to 2), we get :
1.5c + 4( 2200 - c ) = 5050
1.5c - 4c = 5050 - 8800
2.5c = 3750
c = 1500
a = 2200 - 1500
a = 700
Therefore, 1500 children and 700 adults attended the fair.

which of the following is geometric sequence?
Answer:
Choice C
Step-by-step explanation:
A geometric sequence is usually one that multiply or divide to get to the next number in the sequence. So let's go through them to see which one gets multiplied since all of the choices are increasing.
Choice A:
[tex]1^{+3},4^{+1},5^{+4},9^{+5},14[/tex]
Nope that's not what we're looking for.
Choice B:
[tex]3^{+3},6^{+3},9^{+3},12^{+3},15[/tex]
This would be a perfect arithmetic sequence but not the type of sequence we are looking for.
Choice C:
[tex]6^{*3},18^{*3},54^{*3},162[/tex]
Yes! See how this one is multiplying by 3 and not adding or subtracting.
Choice D:
[tex]3^{+2},5^{+3},8^{+5},13^{+7},21[/tex]
Nope this is not it either.

The expression -320+15y represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute. What was the depth of the submarine after 15 minutes?
Step-by-step explanation:
Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :
-320+15y
We need to find the depth of submarine after 15 minutes.
Put y = 15 in the above expression.
-320+15y = -320+15(15)
= -320 + 225
= -95
Hence, the submarine is below sea level at 95 feet.

Arisia puts $500 into a savings account with an annual simple interest rate of 4.5%. If the savings account pays 5% simple interest, how much interest will Arisia earn on her $500 principal over 20 years?
Answer:
$500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 500 × 0.05 × 20 = 500
I = $ 500.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 5% per year
for 20 years is $ 500.00.
Express this number in scientific notation.
31 billion
Answer:
3.1 * 10^10
Step-by-step explanation:
we know 1 billion is 1,000,000,000
In scientific notation
1,000,000,000=1 * 10^9
To find the value of 31 Billion
Multiply the value of one billion for 31
so
31 * 1 * 10^9 = 31 * 10^9
= 3.1 * 10^10

H varies directly to the cube of c.
When H = 40, C = 2.
(a) Express H in terms of c.
Answer:
H in terms of c is H = 5c³.
Step-by-step explanation:
Given that:
H = 40 and c = 2
H varies directly to the cube of c.
Which means that,
H ∝ c³
Let,
k be the proportionality constant.
H = kc³
Putting H=40 and c=2
[tex]40=k(2)^3\\40=k(8)\\40=8k\\8k=40[/tex]
Dividing both sides by 8,
[tex]\frac{8k}{8}=\frac{40}{8}\\k=5[/tex]
Now,
H in terms of c.
H = 5c³
Hence,
H in terms of c is H = 5c³.

There are 31 pink beads and 15 purple beads on Violet's necklace. What is the ratio of the number of beads to the number of pink beads?
Answer:
The ratio of number of purple beads to the number of pink beads is: 15:31
Step-by-step explanation:
Number of pink beads = 31
Number of Purple beads = 15
We need to find ratio of number of purple beads to the number of pink beads
So, The ratio of number of purple beads to the number of pink beads is:
Number of purple beads : Number of pink beads
15 : 31
Since it cannot be simplified further, So
The ratio of number of purple beads to the number of pink beads is: 15:31
