Clare has a recipe for yellow cake she uses 9 1/3 cups of flour to make 4 cakes. Noah will follow the same recipe. He will make c cakes using f cups of flour. What equation would show the relationship between cake and flour?
Answer:
[tex]c=\frac{3}{7}f[/tex]
Step-by-step explanation:
Clare uses [tex]9\frac{1}{3}[/tex] cups of flour to make 4 cakes.
Noah follows the same recipe so the ratio of the ingredients used will be proportional.
If Noah uses f cups of flour for c cakes,
[tex]\frac{c}{f} =\frac{4}{9\frac{1}{3}}[/tex]
[tex]\frac{c}{f} =\frac{4}{\frac{28}{3}}[/tex]
[tex]\frac{c}{f} =\frac{4\times 3}{28}[/tex]
[tex]c=\frac{3}{7}f[/tex]
Therefore, relation between cake and flour used is,
[tex]c=\frac{3}{7}f[/tex]

Select the correct answer. Which number has a terminating decimal expansion? A. 2/7 B.√12 C. 5/8 D. 2/11
Answer:
Option C is correct option.
Step-by-step explanation:
We need to determine which number has a terminating decimal expansion.
Terminating decimal
A decimal number that contains a finite number of digits after the decimal point is called terminating decimal .
for example 0.123 is terminating decimal as it has finite number of digits after decimal point.
Now, we will look at each option to find the terminating decimal
A. 2/7
Converting in decimal form: 0.28571....
As it doesn't contain finite numbers after decimal point, so 2/7 is not terminating decimal.
B.√12
Converting in decimal form: 3.46410....
As it doesn't contain finite numbers after decimal point, so √12 is not terminating decimal.
C. 5/8
Converting in decimal form: 0.625
As it contain finite numbers after decimal point, so 5/8 is terminating decimal.
D. 2/11
Converting in decimal form: 0.18181....
As it doesn't contain finite numbers after decimal point, so 2/11 is not terminating decimal.
Therefore, Option C is correct option.
Answer:
Option C is correct option.

Your answers for #2 and #4 are incorrect.
Step-by-step explanation:
For #2:
For one half hour in the garage, simply divide the one hour rate in half. 5/2= 2.5For #4:
For 1.75 hours in the garage, the answer will be less than your answer for two hours. So, if 2hrs is $10, then the answer for 1.75 hrs must be 7.5

how do you solve systems by graphing
Answer:
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system.

Which relationships describe the angle pair x° and 157°? Select each correct answer. O complementary angles 1570 O supplementary angles o adjacent angles vertical angles
Answer:
Supplementary angles and adjacent angle
Step-by-step explanation:
Both angles x° and angle 157° are supplementary ; this is because the sum of both angles should add up to 180°.Looking closely, each both angles will combine to form angle on a Straight line which from angle theorem adds up to 180°.
Also both angles x° and 157° are adjacent angles most simply because they share a common vertex(this can be interpreted as the point of intersection of the two lines which makes up the diagram.)

A kangaroo hops 2 kilometers in 3 minutes. At this rate how long does it take the kangaroo to travel 3 kilometers?
Answer:
4 minutes 3 seconds
Step-by-step explanation:
Step one:
Given data
A kangaroo hops 2 kilometers in 3 minutes
The rate/speed is
rate/speed= 2/3 km per minute
Required
the time taken to cover 3 km
Step two:
We know that
rate= distance/time
2/3= 3/t
cross multiply we have
2t=3*3
2t=9
divide both sides by 2
t= 9/2
t= 4.5 minutes
t= 4 minutes 3 seconds
You and your friend go to a taco truck for lunch. You order 3 soft tacos and 3 burritos and spend $11.25. Your friend orders 4 soft tacos and 2 burritos and spends $10.00.
Answer: See explanation
Step-by-step explanation:
Let soft tacos be x
Let burritos be y
3x + 3y = 11.25 ......... i
4x + 2y = 10.00 ......... ii
Multiply equation I by 4
Multiply equation ii by 3
12x + 12y = 45 ....... iii
12x + 6y = 30 ....... iv
Subtract iv from iii
6y = 15
y = 15/6 = 2.5
A burrito cost $2.50
Since 3x + 3y = 11.25 .
3x + 3(2.50) = 11.25
3x + 7.50 = 11.25
3x = 11.25 - 7.50
3x = 3.75.
x = 3.75/3
x = $1.25
A soft tacos is $1.25

Answer:
sdgghjjkugzdbhgfbufsfh
if y varies inversely as x and y=23 when x=8 find y when x=4
EQUATION:
[tex]y = \frac{k}{x} [/tex]
––––––––
First, find the constant of variation k using the formula k=xy.
[tex]23 = \frac{k}{8} [/tex]
[tex]k = (8)(23)[/tex]
[tex]k = 184[/tex]
––––––––
Then, find y if x is equal to four using the formula y=184/x.
[tex]y = \frac{184}{x} [/tex]
[tex]y = \frac{184}{4} [/tex]
[tex]y = 46[/tex]

y = 46I need help quick!!!!!!!!

f(x)=x^2. What is g(x)?
given the point (1,4)
A. g(x)=4x^2
B. g(x)=16x^2
C. g(x)=1/4x^2
D. g(x)=(4x)2
Answer:
D. g(x)=(4x)^2
Step-by-step explanation:
(A.P.E.X)
The function g(x) is g(x) = 4x² after applying the tansformation because the f(x) is the parent function option (A) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The options are:
A. g(x)=4x²
B. g(x)=16x²
C. g(x)=1/4x²
D. g(x)=(4x)²
It is given that:
f(x) = x²
From the graph as we can see the function f(x) is the parent function and g(x) is transformed function.
The function g(x):
g(x) = ax²
Plug x = 1
g(x) = 4
4 = 1²a
a = 4
g(x) = 4x²
Thus, the function g(x) is g(x) = 4x² after applying the tansformation because the f(x) is the parent function option (A) is correct.

Use < >, or = to compare the following decimals.
(a) 0.91
0.98
D
D>
(b) 9.07 [ 9.3
?.
(c) 0,90 [ 0.9
Answer:
0.32, 0.45, 0.76.
Step-by-step explanation:
so first you would use your < >,= signs and compare all of them until you have eliminated ALL but one (so 0.91<0.98 this is because 0.98 is close to 1 whole than 0.91) and you would continue this explanation for so on
