Answer:
245
Step-by-step explanation:
This is a ratio
7/10 = 70% = the kids who picked summer which leaves off as 30% for an unknown season
7 : 10
245 : 350
The 7 is how many students chose summer, and the 10 is the number of students there are in general
The 245 is the number of students who chose summer, and the 350 is the number of students there are in general
All we had to do was see how many times 10 goes into 350, which is 35 times. So we multiply 10 by 35 and we get 350. Now whatever we do on one side, we need to do it to the other. So 7 times 35 gives us 245. And that's how I know that out of the 350 students there are in total, 245 of them chose summer.
Hope this helped!

In the triangle, suppose that m∠L = (6x-3)°, m∠M=(2x-6)°, and m∠N =x°.
(a) Write an equation to find x. Make sure you use an "=" sign in your answer.
Equation = _
(b) Find the degree measure of each angle.
m∠L = _°
m∠M = _°
m∠N = _°
9514 1404 393
Answer:
(a) (6x -3) +(2x -6) +x = 180
(b) m∠L = 123°
m∠M = 36°
m∠N = 21°
Step-by-step explanation:
a) The sum of angle measures (in degrees) is 180°. The equation reflects this fact:
(6x -3) +(2x -6) +x = 180
__
b) The equation simplifies to ...
9x -9 = 180
x -1 = 20 . . . . . divide by 9
x = 21 . . . . . . . .add 1
Then the degree measures are ...
m∠L = (6x -3)° = (6·21 -3)° = 123°
m∠M = (2x -6)° = (2·21 -6)° = 36°
m∠N = x° = 21°

Two correspoding sides of similar triangles are 2 and 5. What is the area of the second triangle if the area of the first one is 8
Answer:
The area would be 80
Step-by-step explanation:
Firstly we need the scale factor
At 2 to 5, the scale factor is 5/2 = 1 to 2.5
Mathematically, we have the area of a triangle as:
1/2 * b * h
So, if the other side is x ;
we have that :
1/2 * x * 2 = 8
2x = 16
x = 8
The bigger other side will be;
2.5 * 8 = 20
So the area of the second will be;
1/2 * 20 * 8 = 80

Is (4,-2) the solution of the system of equations shown below? 2X+4Y=-2. -4X+Y=-14. Anders: yes, no, they are the same line
Answer:
No
Step-by-step explanation:
Given
[tex]2x + 4y = -2[/tex]
[tex]-4x + y = -14[/tex]
Required
Is (4,-2) a possible solution?
In (4,-2)
[tex]x = 4[/tex]
[tex]y = -2[/tex]
Substitute [tex]x = 4[/tex] and [tex]y = -2[/tex] in: [tex]2x + 4y = -2[/tex]
[tex]2(4) + 4(-2) = -2[/tex]
Open all brackets
[tex]2*4 - 4*2 = -2[/tex]
[tex]8 - 8 = -2[/tex]
[tex]0 \ne -2[/tex]
The above expression shows that (4,-2) is not a solution and there is no need to check for the second equation.

Stacey earns $15 each week plus $.50 for each customer on her paper route. She
wants to earn at least $25 each week. What equation can she use to find x, the
number of customers she needs to make exactly $25?
Answer:
15 + .50x ≥ 25 (20 customers)
Step-by-step explanation:
to get a minimum of $25 per week, Stacey needs to earn $10 on her paper route since she is already getting $15 per week in general. Now we can divide 10 by .50 to find out how many customers Stacey needs to make $25 per week. 10/.50 is 20 which means that Stacey needs at least 20 customers to make at least $25 per week.
(sorry if this is confusing but I hope it helped)
The equation can be used to find the number of customers is -
25 = 15 + 0.5x
The equation can be used to find the number of customers.
We have Stacey who earns $15 each week plus $ 0.50 for each customer on her paper route. She wants to earn at least $25 each week.
We have to determine which equation can she use to find x, the number of customers she needs to make exactly $25.
Write a equation to represent the count of bacteria (y) after x days such that at x = 0, the bacteria count is 10000 and then increases by 2000 per day.The equation representing the above situation is -
y = 10000 + 2000x = 2000(5 + x)
According to the question, we have -
Money earned by Stacey each week = $ 15
Additional money she earns for each customer = $0.50
Money Stacey wants to earn per week = $25
Net additional money she need = $25 - $15 = $10
Now, she earns -
$0.50 → 1 customer
$1 → [tex]$\frac{1}{0.50}[/tex] customers
$10 → [tex]$\frac{1}{0.50} \times 10[/tex] = 2 x 10 = 20 Customers.
In the form of equation, assume that she needs 'x' customers to make exactly $25.
Therefore -
25 = 15 + 0.5x
The above equation can be used to find the number of customers.

Terry is purchasing a bike that is on sale for 40% off the original price. After a coupon is applied that reduces the sale price by 20%, Terry's final cost for the bike is $168. What was the original price of the bike Terry is purchasing?
Answer: $350
Step-by-step explanation:
Terry bought the bike at $168 after using a coupon that reduced the price by 20%.
The sales price was therefore:
= 168/ (1 - 20%)
= $210
The sales price which is $210, was gotten after a 40% discount was applied on the original price.
Assume that original price was x:
x - (x * 40%) = 210
x - 0.4x = 210
0.6x = 210
x = 210/0.6
= $350
A car dealer advertises a 7% markup over cost. What is the selling price of a car that cost the dealer $13,000?
Answer:
Step-by-step explanation:
The selling price can be shown to be 13000 + 7% * 13000
Selling price = 13000(1 + 7/100) = 13000 (1 + 0.07 ) = 13000 * 1.07
Selling price = 13910

DIG DEEPER! The figure shows the angles used to make a double bank shot in an air hockey game. a. Find the value of x. b. How does the angle the puck hits the edge of the table relate to the angle it leaves the edge of the table? B 7 un E ETT
Answer:
the sides of the air hockey can be used as parallel lines.
m° = angles on a straight line add up to 180. 180 - 64 = 116. 116/2 = 58°
m = 58°
the 64° given is an alternate angle to X.
X = 64°
A particular airport has beacons on the ground 6 km out from the start of each runway. An airplane is directly over this beacon and is at an angle of elevation from the runway of 8°. Calculate the direct line distance from the airplane to the start of the runway
Answer:
6.06 km
Step-by-step explanation:
The information given in the question can be represented by the three sides if a right angled triangle.
Let the direct line from the airplane to the start of the runway be represented by x. So that applying the appropriate trigonometric function, we have;
Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]
Cos [tex]8^{o}[/tex] = [tex]\frac{6}{x}[/tex]
0.9903 = [tex]\frac{6}{x}[/tex]
⇒ x = [tex]\frac{6}{0.9903}[/tex]
= 6.0588
x = 6.06 km
The direct line from the airplane to the stat of the runway is 6.06 km.

Answer: x = 11.5
Step-by-step explanation: Since the line bisects angle BAC, this means angles BAD and DAC equal each other.
To find what angle DAC equals, you divide 75 by 2, which equals 37.5
Then you set 37.5 equal to (3x+3) and solve for x.
37.5 = 3x+3
34.5 = 3x
11.5 = x
