younger brother, Sam, 1.5 times longer to run a mile.
How long does it take Sam to run a mile?
Answer:
18 minutes to run a mile
Step-by-step explanation:
1.5 is equal to 150%. so given that you have 12 minutes you can do what is 150% to 12 so 100% of 12 is 12 and 50% of 12 is 6 and 6 + 12 is 18

Hailey took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.60 plus $0.75 per mile. The total fare was $8.35, not including the tip. Write and solve an equation which can be used to determine xx, the number of miles in the taxi ride.
Answer:
1.60+0.75x=8.35
x=9
Step-by-step explanation:
1.60+0.75x=8.35 will be the equation to determine the number of miles x.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that,
Pickup charge (fixed charge) = $4.60
Charge per mile = $0.75 /mile
Total charge = $8.35
So,
Total charge = pick up charge + Charge per mile × number of mile(x)
8.3.5 = 1.60 + 0.75x
1.60+0.75x=8.35
Hence "1.60+0.75x=8.35 will be the equation to determine the number of miles x".

If 40 is multiplied by a number identify a number that will give a product less than 40 Explain why you chose this number
Answer:
Any negative number or decimal, for example, -1, or 0.5
Step-by-step explanation:
-1 multiplied by 40 turns into -40, which is less that 40
0.5 times 40 is 20, which is less that 40
For the given condition, the product should be less than 40 the value of x must be less than 1.
Given that,
40 is multiplied by a number to identify a number that will give a product less than 40, the number is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the number be x,
40 is multiplied by a number to identify a number that will give a product less than 40,
40 * x < 40
Dividing both sides by 40,
x < 40 / 40
x < 1
Thus, for the given condition, the product should be less than 40 the value of x must be less than 1.

Aron is training for a 10 km marathon swim in 18 weeks. Each week, his training plan
includes a long distance swim. Over the first 6 weeks, Aron swam a total of 18.75 km. Over
the first 10 weeks, Aron swam a total of 36.25 km. Each week, Aron increased the distance
he swam following an arithmetic sequence until the final week.
a. By what distance did Aron increase his total swimming each week?
Answer:
a. 0.25 km
Step-by-step explanation:
For an arithmetic sequence, the sum of all terms up to term n is
sum = n/2[2a + (n - 1)d]
We are given:
sum of first 6 terms = 18.75
sum of the first 10 terms = 36.25
6/2[2a + (6 - 1)d] = 18.75
10/2[2a + (10 - 1)d] = 36.25
3(2a + 5d) = 18.75
5(2a + 9d) = 36.25
2a + 5d = 6.25
2a + 9d = 7.25
4d = 1
d = 0.25
2a + 5(0.25) = 6.25
2a = 5
a = 2.5
The common difference is 0.25 km.
Answer: a. 0.25 km

A survey found that women heights are normally distributed with mean 63.6 in and standard deviation 2.5 in. A branch of military requires women heights to be between 58 in and 80 in
Answer:
See below:)
Step-by-step explanation:
a)
mean = 63.6 , s.d = 2.5. We need to compute Pr(58 <= X <= 80)
The corresponding z-values needed to be computed
z1 = (58 - 63.6)/2.5 = -2.24
z2 = (80 - 63.6)/2.5 = 6.56
Therefore, we get:
Pr(58 <= X <= 80) = Pr( (58 - 63.6)/2.5 <= Z <= (80-63.6)/2.5 ) = Pr(-2.24 <= Z <= 6.56)
= 1 - 0.0125 = 0.9875
98.75 % of the women meet the requirements,Hence not too many women are being denied the opportunity to join this branch of the millitary.
b)
z value for lower 1% = -2.3263
corresponding x value = 63.6 - (2.5X2.3263) = 57.78
Z value for upper 2% = 2.0537
corresponding x value = 63.6 + (2.5X2.0537) = 68.73
The new height requirements is between 57.78 and 68.73 inch

Evan went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 150 mg of sodium and each frozen dinner has 550 mg of sodium. Evan purchased a total of 16 cans of soup and frozen dinners which collectively contain 5200 mg of sodium. Determine the number of cans of soup purchased and the number of frozen dinners purchased.
Answer:
Evan purchased 7 frozen dinners and 9 cans of soup.
Step-by-step explanation:
Since Evan went to the grocery store and purchased cans of soup and frozen dinners, and each can of soup has 150 mg of sodium and each frozen dinner has 550 mg of sodium, and Evan purchased a total of 16 cans of soup and frozen dinners which collectively contain 5200 mg of sodium, to determine the number of cans of soup purchased and the number of frozen dinners purchased the following calculation must be performed:
16 x 550 + 0 x 150 = 8800
8800 - 5200 = 3600
550 - 150 = 400
3600/400 = 9
7 x 550 + 9 x 150 = X
5200 = X
Therefore, Evan purchased 7 frozen dinners and 9 cans of soup.

if f(x) = 3x+2, what is f(5)
Answer:
f(5) = 17
Step-by-step explanation:
Function: f(x) = 3x + 2
x-value: 5
Equation: f(5) = 3(5) + 2
Solve:
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
Warning⚠Many people thin that something like f(x) means that you are multiplying f and x. This is incorrect.
f(x) = 3x + 2 is the same as y = 3x + 2, the f is the name of the function, and you replace a number, like 5, for the x - value.

I need help solving for X
Answer:
x = 63
Step-by-step explanation:
This is a right angle, and we know that there are 90 total degrees in a right angle. Because of this information, we know that the degrees of both angles, added together, should come out to 90. This reasoning looks like this:
[tex]25+(x+2)=90[/tex]
Now, it's much easier to solve for x. I'll start by removing the parentheses and combining like terms.
[tex]25+x+2=90\\25+2+x=90\\27+x=90[/tex]
Now, let's remove 27 both sides to isolate x and figure out what it's equal to.
[tex]27+x=90\\x = 63[/tex]
So, the measure of x is 63 degrees. We can make sure this is correct by using our equation:
Is [tex]25+(63+2)=90[/tex]? Yes, because 63 + 2 is equal to 65, and 65 plus 25 is equal to 90. So our answer is correct.
If you need any more help, let me know! :)
Answer:
x = 63°
Step-by-step explanation:
(x + 2) + 25 = 90
x + 2 = 90 - 25
x + 2 = 65
x = 65 - 2
x = 63°
(x + 2) + 25 = 90
(63 + 2) + 25 = 90
65 + 25 = 90
90 = 90
