10 weeks, Substituion Equation.
Step-by-step explanation:
(Assume that x= 'per week').
We can write this as 50 + 25x=y for Heather's savings, &
200 + 10x=y for Alssa's savings.
We can combine these equations to make 200 +10x= 50+25x, because we know 50+25x=y, like we found out in the first equation. We can now subtract 25x from each side, and subtarct 200 from each side, to get
10x - 25x = 50 - 200, which can be simplified to -15x=-150. If we divided each side by -15, we get 10. Therefore, it will take 10 weeks for them to have the same amount of money. I think this is the Substituaion Equation

Which expression is equivalent to 7(y - 8)?
Answer:
In this question , we have to find the equivalent expression.
Step-by-step explanation:
To find the equivalent expression of a fraction, we can either multiply numerator and denominator by same variable or same number, or we can divide both numerator and denominator by same number or same variable .
So if we multiply both numerator and denominator by 2, we will get 14/16
Step-by-step explanation:
7(y-8) = 7y-7(8) = 7y- 56

if cot a =5/12 then find the value of cosec A
Answer:
cosec A = 13/12
Step-by-step explanation:
Mathematically, we want to find the value of cosec A
sides 5,12 and 13 represent a Pythagorean triple. This means the last side of the right-triangle that contains 5 and 12 is 13
cot is the ratio of the adjacent to the opposite
Hence ; 5 represents the adjacent while 12 represents the opposite
cosec is the inverse of sine which is the hypotenuse to the opposite ratio
So, we have ;
cosec A = 13/12

Answer:
978 in^2
Step-by-step explanation:
the area of the rectangle:
24in X 30in = 720 in^2
the area of the two similar triangles:
12 X 9 / 2 + 12 X 9 / 2 = 108 in^2
the area of the last triangle:
20 in X 15 in /2 = 150in^2
.
the total area is the sum of the areas:
720in^2 + 108in^2 + 150in^2 = 978in^2.

Here is the Question:
The system y = 4x - 7 and 2y = ax + b has no solution. Determine the value(s) of a and b for which this is true.
Answer:
a = 8
b ≠ 18
Step-by-step explanation:
y = 4x - 7
2y = ax + b
For there to be no solution, the lines (if graphed) should be parallel meaning that their slopes are equal but the y-intercepts are different
y = mx +b is the equation of a line where m is the slope and b is the y-intercept
Multiply the first equation by 2
2y = 8x - 14
2y = ax + b
So a has to equal 8
b can be anything except 14 (otherwise the lines would be the same)
9514 1404 393
Answer:
a = 8b ≠ -14Step-by-step explanation:
Multiply the first equation by 2 and you get ...
2y = 8x -14
Compare to the second equation ...
2y = ax +b
The pair of equations will have no solution if they describe parallel lines. That is, a = 8 and b ≠ -14.
__
For a ≠ 8, the lines will intersect and there will be one solution.
For a = 8 and b = -14, the lines will be coincident, and there will be infinite solutions.

How much longer will it take a car traveling at an average speed for 2 miles per hour to make the trip from San francisco to New York than a Dc10 jet flying at an average speed of 500 miles per hour
Answer:
1445.6 hours
Step-by-step explanation:
Distance between New York and San Francisco = 2902.8 miles (checked online)
Average speed of car = 2 mi/hr
Average speed of jet = 500 mi/hr
Time taken by Jet:
Time taken = Distance / speed
Time taken = 2902.8 / 500
Time taken = 5.8056 = 5.8 hours
Time taken by Car :
Time taken = Distance / speed
Time taken = 2902.8 / 2
Time taken = 5.8056 = 1451.4 hours
Time difference :
1451.4 - 5.8 = 1445.6 hours

Answer:
a.12 feet is the answer pythagorean theory
Answer: 12
Step-by-step explanation:
For this question you would have to use pythagoras' theorem.
The formula to work out the shorter side is a²=c²-b² so for this question it would be a²=13²-5² when you put the numbers in the formula.
13²=169
5²=25
a²=169-25
a²=144
Then to work out a on it's own you would square root 144.
The square root of 144 is 12.
Tyrell and Channing both work at the same fast food restaurant. Channing works 5 hours and earns $42.75. Tyrell's earnings are modeled by the equation E = 8h, where h is the number of hours worked and E represents his total earnings. Which of the following statements must be true?
a.Channing earns more money per hour than Tyrell.
b.Tyrell earns more money per hour than Channing.
c.Channing and Tyrell each earn the same amount of money per hour.
d.Tyrell works twice as many hours per week as does Channing.
Answer:
A. Channing makes $8.55 an hour compared to Tyrell who only makes $8 an hour.
Step-by-step explanation:
To find how much Channing makes an hour, divide the amount earned ($42.75) by the hours he worked (5). So, 42.75/5=8.55 which is Channing's hourly wage. Tyrell's hourly wage was already given to us in the equation E=8h. 8 times his hours works= his earnings. 8.55>8.00
What is the result when the number 27 is increased by 1.6%?
Answer:
27.432
Step-by-step explanation:
27 = 100%
divide by one hundred to get one percent
0.27 = 1%
Divide this by two to get 0.5%
0.135 = 0.5%
Divide by 5 to get 0.1%
0.027 = 0.1%
Add
0.27 + 0.135 + 0.027 = 0.432 =1.6%
Add 0.432 to 27
27.432
Write 18 out of 30 as a fraction in its simplest form.
a) 6/10
C) 18/30
b) 60/100
d) 3/5
Answer:
d). 3/5.
Step-by-step explanation:
The greatest common factor of 18 and 30 is 6, so we divide top and bottom of the fraction by 6:
18/30
= (18/6) / (30/6)
= 3/5.
In ΔQRS, q = 99 cm, r = 17 cm and s=96 cm. Find the measure of ∠S to the nearest degree.
74.95 or 75 I think
Step-by-step explanation:
I put it into a triangle calculator, so it could be wrong.
The measure of the angle S from the given triangle QRS is 65°.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔQRS, q = 99 cm, r = 17 cm and s=96 cm.
96²=99²+17²-2×99×17cosS
9216=9801+289-198cosS
-874=-198cosS
cosS=4.14
∠S=65°
Therefore, the measure of the angle S is 65°.

find the volume please
Answer:
Volume ≅ 1407.4
Step-by-step explanation:
Since this shape is a cylinder we need to use the formula for the bolume of a cylinder, which is...
V = π[tex]r^{2}h[/tex]
(where "h" is the heigh of the cylinder)
Now we just substatute the values, and so we get...
V = π[tex]r^{2} h[/tex]
V = π[tex]8^{2}(7)[/tex]
V = 64π(7)
V = 448π
V ≅ 1407.4
