Tell whether the ratios form a proportion. 30/75, 24/60
Given:
The ratios are [tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex].
To find:
Whether the ratios form a proportion or not.
Solution:
If two ratios represent the same relationship then they form a proportion.
We have,
[tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex]
Write the given ratios in the simplified forms.
[tex]\dfrac{30}{75}=\dfrac{15\times 2}{15\times 5}[/tex]
[tex]\dfrac{30}{75}=\dfrac{2}{5}[/tex]
And,
[tex]\dfrac{24}{60}=\dfrac{12\times 2}{12\times 5}[/tex]
[tex]\dfrac{24}{60}=\dfrac{2}{5}[/tex]
Since [tex]\dfrac{30}{75}=\dfrac{24}{60}=\dfrac{2}{5}[/tex], therefore the ratios form a proportion.

Susie earns $9.00 per hour. She worked 37 hours from Monday to Friday. What were her total wages?
a.) $450
b.) $333
c.) $324
Answer:
b
Step-by-step explanation:
9 x 37 = 333
Answer:
$333
Step-by-step explanation:
As, the total hours Eleanor works = 37
And per hour he gets = $9
So the total wage her gets = $9 x 37
= $333
Megan's dog Sparky eats 4 1/4 cups of food each day. EXPLAIN how Megan can determine how much food to give Sparky if she needs to feed him only 2/3 as much. SOLVE the problem. (you need to solve AND explain, do not just solve) *
Answer:
If Megan is already feeding him 4 1/2 cups of food and she "needs to feed him only 2/3 as much" then you are looking for a smaller number. 6 3/8 cups would give the dog more food.

Answer:
d
Step-by-step explanation:
in order for it to be a triangle the angles have to add up to equal 180
5+75+100=180 so its not a
10+80+90=180 so its not b
20+60+100=180 so its not c
45+45+45=135 so its d because the angles dont add up to 180
50+50+80=180 so its not e
Answer:
D
Step-by-step explanation:
To be a triangle, you have to have 180 degrees. if you add up all of the sides, it should give you 180. If it doesn't, it isn't a triangle. I hope that helped! :)

Solve for r.
–6(r − 98) = 78
Answer:
r = 85
Step-by-step explanation:
→ -6 ( r - 98 ) = 78→ r - 98 = -13→ r = -13 + 98→ r = 85conclusion:
so the value of r is 85
Step-by-step explanation:
First, divide both sides of the equation by -6.
-6(r-98)÷6=78÷6
This gives us r-98=-13
Then, add 98 to both sides.
r-98+98=-13+98
The answer is r=85

Find the composition (f ∘ g)(–2) for the functions f(x) = 2x + 1 and g(x) = x2 – 3.
Answer:
Step-by-step explanation:
(f∘g)(x) = f(g(x))
= f(x²-3)
= 2(x²-3) + 1
= 2x² - 5
(f∘g)(-2) = 2(-2)² - 5
= 2·4 - 5
= 8 - 5
= 3
The composition (f ∘ g)(–2) for the functions f(x) = 2x + 1 and g(x) = x2 – 3 will be 3
What is composition of a function ?
The composition of a function is an operation where two functions say f and g generate a new function say h in such a way that h(x) = g(f(x)). It means here function g is applied to the function of x. So, basically, a function is applied to the result of another function.
The notation used for composition is: (f o g)(x) = f(g(x))
(fog)(x) = f(g(x))
this implies , (fog)(-2) = f(g(2))
given :
f(x) = 2x + 1
g(x) = x2 – 3
(fog)(x) = f(g(x)) = f(x^2 - 3)
= 2 (x^2 -3) +1
= 2x^2 - 5 equation 1
fog(-2) = f(g(2))
substituting the value of x = 2 in equation 2
= 2 * (2)^2 -5
= 3

2) Richard, Henry and Gavin share some sweets in the ratio 4:1:3. Richard gets 7 more sweets
than Gavin. How many sweets does Henry get?
Answer:
6
Step-by-step explanation:
Richard gets 7 more sweets than Gavin which would probably make Richard have the most so in total he should have around 8 whilst Gavin has 1 so right now we have 4:1:?. Basing off the fact that Richard would have the most sweets Henry would have to have 6 sweets to be able to divide half of it for 3. 4:1:3

Find the measure of angle 1
Answer:
112 degrees
Step-by-step explanation:
Since the two sides opposite of angle 1 and 2 are congruent, as shown by the double tic marks, the angles are conguent. The total sum of all angles must be 360 degrees, so we know 90 degrees was given, as well as 46 degrees. That's 136 degrees together, subtract that from 360 and you get 224. Angles 1 and 2 are congruent so both add to 224, therefore each angle is 112 degrees.

Use the information to find an equation (y=mx+b) for the amount of Sponsorship money (Y) you an make for each day of the trip. Show your work and explain your steps below. Coca Cola 5 days - $134 10 days - $164 15 days - $194 20 days - $224
Answer:
y = 6x + 104
Step-by-step explanation:
Given the equation in the form:
y = mx + b
m = slope ; b = intercept
Given the data:
5 days - $134 10 days - $164 15 days - $194 20 days - $224
To obtain the slope, Pick the points :
(5, 134) and (20, 224)
Slope = y2 - y1 / x2 - x1
Slope, m = (224 - 134) / (20 - 5) = 90 / 15 = 6
Plugging into the equation :
We have ;
y = 6x + b
Picking any point from the data and plugging in to solve for b:
(10, 164)
164 = 6(10) + b
164 = 60 + b
b = 164 - 60
b = 104
Equation finally becomes ;
y = 6x + 104
7(x-4)=4x+5 whats X?
Answer:
x = 11
Step-by-step explanation:
In this question, you would solve for x.
Solve for x:
7(x - 4) = 4x + 5
Use the distributive property.
7x - 28 = 4x + 5
Subtract both sides by 4x.
3x - 28 = 5
Add 28 to both sides.
3x = 33
Divide both sides by 3.
x = 11
Your final answer would be x = 11
Answer:
x=11
Step-by-step explanation:
First, do the parentheses (PEMDAS).
7(x-4)=4x+5 to 7x-28=4x+5
Then, add 28 to either side to get all the numbers on one side.
7x-28=4x+5 to 7x=4x+33
After that, subtract 4x to get all the x's on one side.
7x=4x+33 to 3x=33
Finally, divide by 3 to get your final answer.
3x=33 to x=11

There is a bag with 50 popsicles inside. 5
are red, 15 are orange, 12 are blue, 8 are
yellow and 10 are purple. If you were to
grab one popsicle from the bag, what is
the probability that it is purple?
Answer:
25%
Step-by-step explanation:
We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.

The question is in the picture
Answer:
C. a= 4, b= 2
Step-by-step explanation:
In a parallelogram, opposite sides are equal.
So, 4a+1 = 2a+9
On solving, we get, a= 4
Similarly, 6b= 11b-10
On solving, we get, b= 2
Answer:
answer: option C: a=4,b=2
explanation:
opposite sides of a parallelogram are equal so,
QP =RS
6b=11b-10
I. e 6b-11b = -10
I. e. -5b = -10
I. e. - b = -10/2
I. e -b = -2
by removing minus sign from both the sides...
b =2
again opposite sides of a parallelogram are equal so,
QR =PS
4a + 1 = 2a + 9
I. e 4a- 2a = 9 - 1
I. e 2a = 8
I. e a = 8/2
therefore a= 4
so the answer is a=4 and b= 2
