Answer: Bridget will get $9
Step-by-step explanation:
Let the ratio of sharing between Stephen and Bridget be 4x and x
respectively .
According to the question ,
Stephen gets $27 more than Bridget.
Then ,
4x - x = 27
→ 3x = 27
→ x = 9
Amount of money that Bridget gets = $ 9
What are the solutions to the quadratic equation x2 – 16 = 0?
O x = 2 and x = -2
x = 4 and x = -4
x = 8 and x = -8
x = 16 and x = -16
Answers
Answer: x=8 and x=-8
Step-by-step explanation:
To find the solutions of the quadratic equation, you want to factor it and set it equal to 0.
x²-16=0
(x+8)(x-8)=0
x+8=0
x=-8
x-8=0
x=8
Now that we have factored and set the factors equal to 0, we found that the solutions are x=-8 and x=8.
Lucas attends 8 classes each day. If each class is about
45 minutes long, about how long will Lucas have been
in school when he starts his fourth class of the day?
Answers
He will have 3 classes done before starting the fourth class.
3 classes x 45 minutes per class = 135 minutes.
1 hour = 60 minutes
134 minutes = 2 hours and 15 minutes.
Before the fourth class starts he was at school for 2 hours and 15 minutes

[tex]V = \pi * 5^2(13) +\frac{1}{3}\pi * 5^2 (12)[/tex]
Step-by-step explanation:
Given:
The figure is a combination of a cone and a cylinder
Radius (of both), [tex]r = 5[/tex]
Height of Cylinder, [tex]H_1 = 13[/tex]
Height of Cone, [tex]H_2 = 25 - 13 = 12[/tex]
Required:
Volume of the figure
Let V represents the volume of the figure;
[tex]V_1[/tex] represents the volume of the cylinder
[tex]V_2[/tex] represents the volume of the cone
So, [tex]V = V_1 + V_2[/tex]
Where [tex]V_1 = \pi r^2H_1[/tex] and [tex]V_2 = \frac{1}{3}\pi r^2 H_2[/tex]
So, V becomes
[tex]V = \pi r^2H_1 + \frac{1}{3}\pi r^2 H_2[/tex]
Factorize the above expression
[tex]V = \pi r^2(H_1 + \frac{1}{3}H_2)[/tex]
Substitute [tex]r = 5[/tex]; [tex]H_1 = 13[/tex];[tex]H_2 = 12[/tex]
[tex]V = \pi * 5^2(13 + \frac{1}{3} * 12)[/tex]
[tex]V = \pi * 5^2(13 + \frac{1}{3} * 12)[/tex]
Open Bracket
[tex]V = \pi * 5^2(13) +\pi * 5^2 \frac{1}{3} (12)[/tex]
Reorder
[tex]V = \pi * 5^2(13) +\frac{1}{3}\pi * 5^2 (12)[/tex]

Pat starts with two identical square pieces of paper. On the first one, she draws straight lines that divide the paper into a 3-by-3 grid of squares. The total length of the lines she draws is 18cm.
On the second piece of paper, Pat draws straight lines that divide the paper into a 6-by-6 grid of squares.
what is the total length of the lines that Pat draws on the second piece of paper?
Answers
Answer:
45 cm
Step-by-step explanation:
2 lines will divide the square in thirds. 2 additional lines will divide those thirds into ninths. Pat's 4 lines total 18 cm.
To divide the square into sixths requires 5 lines. To divide it into 36ths requires 5 additional lines. Hence the total number of lines on the second paper is 10/4 = 5/2 times the total on the first paper.
The total length of lines on the second paper is ...
(5/2)(18 cm) = 45 cm
Answer:

Answers
Answer:
Charlie has 6 and Leo has 4
Step-by-step explanation:
6-1=5 and 4+1= 5
brainliest plsss
Answer:
In the beginning, Leo had 3 cars and Charlie had 3 cars.
In this problem, the statements seem to never be true if applied in the initial value. But if we take the value from the first statement and take it in the second, Leo and Charlie having 3 cars is true.
Step-by-step explanation:
Charlie said to Leo that if you give me one car, then i will have twice as many cars as you have.
[tex](L_{1} - 1) = 2L_{2} = C_{2}[/tex]
From that statement after Leo gives Charlie a car, we'll have something like:
Charlie's Leo's
2 1
4 2
6 3
Also, from that statement we can imply that we're not dealing with a great amount of cars, because the next statement won't be true.
Leo said if Charlie gives him a car, they will be equal.
[tex]L_{1}= C_{1} - 1[/tex]
Another thing is that if the second consideration holds true after the first statement. I will considerate that.
So,
In the beginning, Leo had 3 cars and Charlie had 3 cars.
In this problem, the statements seem to never be true if applied in the initial value.

It takes 160 ribbons to make 4 football mums. What is the constant of proportionality that relates the number of football mums made, y, to the number of ribbons used, x? 40 140 80 14
Answers
Answer:
40
Step-by-step explanation:
If two variable y and x are related to one other
then they can be represented as y = kx.
where k is constant of proportionality
Number of football mums is represented by y
and number of ribbons is represented by x
Then y = kx
Also, It takes 160 ribbons to make 4 football mums
substituting y with 4 and
substituting x with 160 in y = kx, we have
4 = k*160
=> k = 4/160 = 1/40
Thus, constant of proportionality is 1/40.
But here option given are 40 140 80 14
so ,equation can be represented as
x = ky
substituting y with 4 and
substituting x with 160 in x = ky , we have
160 = k*4
=> k = 160/4 = 40
Thus, for equation x = ky , constant of proportionality is 40.

What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.
The quadratic function is given below.
f(x) = 4(x + 6)²+ 5
Convert the equation into a standard form. Then we have
f(x) = 4(x + 6)²+ 5
f(x) = 4(x² + 12x + 36)+ 5
f(x) = 4x² + 48x + 144 + 5
f(x) = 4x² + 48x + 149
The numerical values in the equation for a, b, and c will be 4, 48, and 149, respectively.

50% increase followed by a 33 1/3% decrease
Answers
Answer:
A 50% increase followed by a 33/1/3% decrease. = ? (1 + 0.5)*(1 - 0.3333333) = 1.5 * 0.666667 = 1. Result is same as original.
A 50% increase followed by a 33 1/3% decrease is a net decrease of 16 2/3%.
Here is the explanation:
A 50% increase means that the value is multiplied by 1.5.
A 33 1/3% decrease means that the value is multiplied by 0.6666666666666666.
So, the net effect of the two changes is:
(1.5 × 0.6666666666666666) = 1 - (1/6) = 0.8333333333333334
This is a decrease of 16 2/3%.
For example, if you start with a value of 100, then a 50% increase followed by a 33 1/3% decrease will result in a final value of 83.33.
