Answer:
3/5 c + 70 = 1650.
Step-by-step explanation:
If c is the number of calories in the cheeseburger, we can see that the entire number of calories for the meal is 3/5 c + 70 = 1650.
If we want to isolate c, we can subtract both sides by 70.
3/5 c = 1580
Answer:
C = [5(1650 - 70)]/3
Step-by-step explanation:
We write the equation: 1650 = 70 + 3C/5
Subtract 70 from both sides: 1650 - 70 = 3C/5
Multiply 5 on both sides: 5(1650 - 70) = 3C
Divide 3 on both sides : C = [5(1650 - 70)]/3
The International Business Club starts the school year with $250.50 in their account. They spend $35 each month on activities. The Future Agricultural Leaders Club starts with $300 and spends $45.25 each month. Which equation can be used to find m, the number of months it will take for both accounts to have the same amount of money? 250.5 + 35m = 300 + 45.25m 250.5 – 35m = 300 – 45.25m 250.5m – 35 = 300m – 45.25 250.5m + 35 = 300m + 45.25
Answer:
250.50 - 35m = 300 - 45.25m
Step-by-step explanation:
Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other
The equation will be 250.50 - 35m = 300 - 45.25m
The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m
Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.
Answer:
b) 250.5 – 35m = 300 – 45.25m

When you multiply a negative and a negative, it is going to be a positive number. In this case, we're multiplying -3 and -7, which is equal to 21. If you're not sure of the answer for multiplication problems like this, just use a calculator to check your work.

h = ?S = ?Solution:
V = πr²hh = V/πr² = 800/(π8²) = 3.98 cmS = 2πr (r+h) = 16π(8+3.98) = 602.18 cm²solve the product of : 0.017 and 10
(( TYPE the STEPS you used to set up the problem and type your steps to solve. )) THANK YOU!!
The product of any two numbers is the result of multiplying them
You can use pencil and paper to get the job done, or use a calculator.
A shortcut is to simply move the decimal over 1 spot to the right.
This is because multiplying 0.017 and 10 is the same as 0.017*10^1, where the exponent of positive 1 means "move decimal point 1 spot to the right". This only works if you multiply by powers of 10.
Answer: 0.17write the point-slope equation of the line that contains the point (1, -4) and has slope - 1/3.

the ratio of adults to children attending a new exhibit at the museum was found to be 8:5 based on this ratio , if 390 people attended one day , how many would be children
Answer:
150 children
Step-by-step explanation:
Ratio of adults to children= 8:5
Let the number of adults be 8 units and
the number of children be 5 units.
Total number of people
= 8 +5
= 13 units
Since there are 390 people,
13 units ----- 390 people
1 unit ----- 390 ÷13= 30 people
Number of children= 5 units
5 units ----- 30 ×5= 150 people
Thus, there are 150 children.
Marta has 1 cubic yard of sand to build a wall in the shape of a rectangular prisim that is 10 inches tall and 5 inches wide to the nearest foor what will be the length of the wall
Answer: 933.12 inches
Step-by-step explanation:
Givem that Marta has 1 cubic yard of sand to build a wall in the shape of a rectangular prisim that is 10 inches tall and 5 inches wide to the nearest foor
1 cubic yard = 46656 cubic inches
Volume = Length × width × height
Substitute all the parameters
46656 = 10 × 5 × height
46656 = 50 height
Height = 46656 / 50
Height = 933.12 inches

If f(x) = 2x+7 and g(x) = -3x+5, what is f(g(1))?
Answer:
[tex]f(g(1))=11[/tex]
Step-by-step explanation:
So we have the two functions:
[tex]f(x)=2x+7\text{ and } g(x)=-3x+5[/tex]
And we want to find f(g(1)).
So, let's find g(1) first:
[tex]g(x)=-3x+5[/tex]
Substitute 1 for x:
[tex]g(1)=-3(1)+5[/tex]
Simplify:
[tex]g(1)=-3+5[/tex]
Add:
[tex]g(1)=2[/tex]
So:
[tex]f(g(1))=f(2)[/tex]
Now, substitute 2 for x in f(x):
[tex]f(x)=2x+7\\f(2)=2(2)+7[/tex]
Multiply:
[tex]f(2)=4+7[/tex]
Add:
[tex]f(2)=11[/tex]
So:
[tex]f(g(1))=11[/tex]

When analyzing three linear functions, Michele noticed that they all intersected at the point (5, 3). What conclusion can Michele come to about the linear function with the smallest slope?
Answer:
The linear function with the smallest slope must be multiple of one of the other two linear functions if all functions are coplanar. Otherwise, they intersect at the given point in space.
Step-by-step explanation:
A system of two linear functions with two variables have an unique solution on a given plane, as there are three linear function, it means that linear function with the smallest slope must be multiple of one of the other two linear functions.
But, if those functions are not all coplanar and have 3 variables, they intersect at the given point.
Find the prime factors of 60 by dividing by prime numbers.
Let's start with the smallest prime number 2
60/2 = 30
Divide that result over 2
30/2 = 15
We can't divide this by 2 because 15/2 = 7.5 isn't a whole number
Let's move onto 3
15/3 = 5
The result is a prime number, so we stop.
The values we divided as denominators were: {2, 2, 3}
We add the result 5 to the set to completely list all of the prime factors of 60
The prime factorization would be
60 = 2*2*3*5which is the same as saying
60 = 2^2*3*5In the diagram below, ZDAB and ZDAC are adjacent
angles.
Complete Question: In the diagram below, <DAB and <DAC are adjacent angles. If m<DAC = 25°, what is m<DAB in degrees? What is m<BAC in degrees?
Answer:
m<DAB = 80°
m<BAC = 105°
Step-by-step explanation:
Generate an equation that will help you find the value of x.
Since m<DAC = 25°, therefore, x - 20 = 25°
Use this equation to find x
x - 20 = 25
Add 20 to both sides of the equation
x - 20 + 20 = 25 + 20
x = 45
m<DAB = 2x - 10
Plug in the value of x
m<DAB = 2(45) - 10 = 90 - 10 = 80°
m<BAC = m<DAC + m<DAB
m<BAC = 25 + 80 = 105°
p2-16p+48=0 Please solve this math problem
Answer:
( p - 4 ) ( p - 12 ) = 0
Step-by-step explanation:
To factor this equation, let's apply the quadratic formula.
p^2 - 16p + 48 = 0
Let a = 1, b = -16, c = 48
[-b +/- sqrt(b^2 - 4(a)(c))] / 2 (a)
[- (-16) +/- sqrt( (-16)^2 - 4(1)(48)) ] / 2 (1)
= [ 16 +/- sqrt( 256 - 192) ] / 2
= [ 16 +/- sqrt(64) ] / 2
= [16 +/- 8] / 2
p = (16 + 8) / 2 ; p = (16 - 8) / 2
p = 24 / 2 ; p = 8 / 2
p = 12 ; p = 4
Hence, this equation factors into the following:
( p - 4 ) ( p - 12 ) = 0

add similar items
= 8x^2 + 5y + 1 - 3 + 3
= 8x^2 + 5y + 1
how many 2/3 cups can go into 9 cups
Hello there! :D
Today we're gonna learn some math, whoopie!
Alright, so we want to know how many 2/3 cups can go into 9 cups!
Firstly, I want to turn 9 cups into a fraction with the denominator of 3.
Let me do it all fancy for you:
[tex]9=\frac{x}{3}[/tex]
We know we want the denominator to be three, now we just need to do the opposite action (multiplication) to the other side to find what "x" is!
[tex]9*3= \frac{x}{3}*3[/tex]
If you have trouble understanding that step, let me know!
[tex]x=27[/tex]
Enter that into the fraction and we have:
[tex]\frac{27}{3}[/tex]
Notice that 27 is not an even number!
Now, we can the numerator of 27/3s and divide it by the numerator of 2/3s.
[tex]27/2=13.5[/tex]
This is not a whole answer, but the question is asking how many 2/3 cups can go into nine cups. Half of a 2/3 cup does not equal a 2/3 cup, so the answer would be 13 cups.
I hope this helps you can you have a wonderful day,
Kai xx
The number of 2/3 cups that can go into 9 cups is [tex]13\frac{1}{2}[/tex]
Total number of cups = 9
The number of 2/3 cups we can get from 9 cups = x
To get the number of 2/3 cups in 9 cups, we will divide 9 by 2/3
Number of 2/3 cups in 9 cups = 9 ÷ 2/3
Number of cups in 9 cups = 9 x 3/2
x = 27/2
x = 13.5
The number of 2/3 cups that can go into 9 cups is [tex]13\frac{1}{2}[/tex]

A cone and cylinder have the same height and their bases are congruent circles. If the volume of the cylinder is 120 cubic inches, what is the volume of the cone?
Answer:
Volume of cone = 40 in³
Step-by-step explanation:
Given:
Volume of cylinder = 120 in³
Height of cylinder = Height of cone
Radius of cylinder = Radius of cone
Find:
Volume of cone
Computation:
Volume of cylinder = πr²h = 120 in³
Volume of cone = (1/3)πr²h
So,
Volume of cone = (1/3)(120)
Volume of cone = 40 in³
