Step-by-step explanation:
Rise of y-value = (-4) - (3) = -7.
Run of x-value = (8) - (6) = 2.
Slope of the line = Rise / Run = (-7) / (2) = -3.5.
a particular tree is 18 m tall : a model of it was built with a. scale of 4 cm : 3m how tall is the model.
Answer:
24 cm
Step-by-step explanation:
We can set up a ratio of 18 m / x cm = 3 m / 4 cm because we know that it's a scale.
Cross multiplying, we get 3x = 72. Divide both sides by 3 and we have x = 24 cm.
We can also consider it by just dividing 18 m by 3 m to find the scale factor, which is 6. We then multiply the 4 cm by 6 to get 24 cm as well.
A baker sold 35% of the cakes she baked, if she baked 80 cakes, how many cakes did she sell?
Answer:
28
Step-by-step explanation:
find 35% off 80 cakes
35% * 80
Converting percent to decimal:
35%/100 = 0.35
0.35 * 80
28
Therefore the baker sold 28 cakes out of the 80 cakes she baked. Hope this helps!
I think 35% of 80 is 28.

Answer:
BQ = 16
QE = 8
Step-by-step explanation:
Centroid of a triangle divides the median in the ratio 2 : 1
Here, let BQ = 2x and QE = x
BQ + QE = BE
2x + x = 24
3x = 24
x = 24/3
x = 8
2x = 2*8 = 16
BQ = 16
QE = 8

An escalator in the mall rises to a platform and makes a 30 degrees angle with the ground. If the platform is 76 feet above the ground, how long is the escalator?
9514 1404 393
Answer:
152 feet
Step-by-step explanation:
A triangle modeling the situation has the unknown length as its hypotenuse, and the given platform height as the side opposite the angle. The relevant trig function is ...
Sin = Opposite/Hypotenuse
sin(30°) = (76 feet)/(escalator length)
escalator length = (76 feet)/sin(30°) = (76/0.5) feet
escalator length = 152 feet

The garden club earned $15, 15 per hour by weeding neighborhood gardens for t hours. A generous donor has agreed to double their earnings.
How much did the garden club earn in all?
Answer:
The answer should be $30.
Answer:
30 * t
Step-by-step explanation:
The garden club earned $15 per hour by weeding neighborhood gardens for t hours.
A generous donor has agreed to double their earnings.
Double their earnings means we multiply by 2
So earning 15 per hour becomes 2*15 = 30 per hour
Given the number of hours is t
Earnings = $30 times number of hours
Earnings = 30 * t

solve each system of equations algebraically y= x-6 y= 2x
Answer: x = -6
Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.
y = x - 6
y = 2x
2x = x - 6 (substitute the y value into the equation)
1x = -6 (subtract x on each side)
x = -6 (1x is basically saying x so you do not need to divide)

If x = -2, which inequality is true?
Answer
F
2x + 6 6
H
-5 + 3x > 1
J
3 – x < 10
Answer:
J
Step-by-step explanation:
If I remember correctly then its J
Answer:
Definitely J.
Step-by-step explanation:
plug in -2 into the where the x is.
so the equation is 3 - -2<10
it becomes 3 +2<10 because the minus and negative signs cancel each other out, making the equation true.
Figure ABDC is a parallelogram find the information below
Please help thank you
9514 1404 393
Answer:
DC = 16∠DCB = 120°EB = 10.2∠ADC = 60°∠ABE = 17°Step-by-step explanation:
The figure is a parallelogram, so ...
AB ≅ DC = 16
Opposite angles are congruent, so ...
∠DAB ≅ ∠DCB = 120°
The diagonals cross at their midpoints, so ...
ED ≅ EB = 10.2
Adjacent angles in a parallelogram are supplementary, so ...
180° -∠DAC = 180° -120° = ∠ADC = 60°
The sum of angles in ∆ABD is 180°, so ...
180° -120° -43° = ∠ABE = 17°

Jada and Noah wanted to find the total volume of a cube and a rectangular prism. They know that the prisms volume is 20 cubic units, and they know that the cube has side lengths of 10 units. Jada says the total volume is 27,000 cubic units. Noah says it is 1,020 cubic units. Do you agree with either of them?
Answer:
Noah answer is the correct answer
Step-by-step explanation:
The solution to the above question is given as:
Total Volume = Volume of the prism + Volume of the cube
Volume of the prism = 20 cubic units
Volume of a cube = (Side length)³
= 10³ = 1000 cubic units
Hence: The total volume =
20 cubic units + 1000 cubic units
= 1,020 cubic units
Therefore, I agree with Noah's answer.
Peaches are being sold for $2 per pound.The customer created a model to represent the total cost of peaches bought. If x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y?
The values of both x and y can be any real number.
The values of both x and y will be real numbers greater than or equal to 0.
The value of x and y will always be zero
The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.
Answer:
B - The values of both x and y will be real numbers greater than or equal to 0.
The answer choice that best describes the values of x and y is B - The values of both x and y will be real numbers greater than or equal to 0.
Calculations and Parameters:Given that peaches are being sold for $2 per lb.
If we define x as the number of pounds that you buy, and y as the cost of these peaches, we can write the function:
y = $2*x
Therefore, the best description of the values of x and y is found in option B. The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

An airplane can cruise at 570 mph. How far can it fly in 4/3 hours?
Answer:
The plane can fly 760 miles in 4/3 hours.
Step-by-step explanation:
Given that:
An airplane can cruise at 570 miles per hour.
We have to find the distance travelled by train in 4/3 hours.
Distance = Speed * Time
Distance = [tex]570*\frac{4}{3}[/tex]
Distance = [tex]\frac{2280}{3}[/tex]
Distance = 760 miles
Hence,
The plane can fly 760 miles in 4/3 hours.

Answer:
f(-10) = -1/2
f(0) = -3
Step-by-step explanation:
Here, given the equation for f(x) we want to get the value of f(x) for each value of x supplied
We proceed as follows
f(-10) = 6/-10-2 = 6/-12 = -1/2
f(0) = 6/(0-2) = 6/-2 = -3

Multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions
2(2x + 3) - 9x = - 24
4x + 6 - 9x = - 24
- 5x + 6 = - 24 ( subtract 6 from both sides )
- 5x = - 30 ( divide both sides by - 5 )
x = 6
13. The sum of the measures of angle Mand angle Ris 90°.
• The measure of angle Mis (5 x + 10).
• The measure of angle Ris 55°.
What is the value of x?
Answer:
x=5
Step-by-step explanation:
If the sum of the measures of angle M and R is 90 degrees, and you know that angle R is 55 degrees, subtract angle R from the total angle. Then, solve for M
90 - 55 = 35
5x + 10 = 35
5x = 25
x = 5

If Bill works on Saturdays, he earns $9 per hour (h), plus a $10 bonus for working on the weekend. He wrote a Function, f(h) = 9h + 10, to help calculate how much he would earn working different numbers of hours next Saturday. How much will Bill earn for 5 hours and 12 hours?
Answer:
[See Below]
Step-by-step explanation:
For 5 hours: f(5)
f(5) = 9(5) + 10
f(5) = 45 + 10
f(5) = 55
Bill would work earn $55 if he worked for 5 hours.
For 12 hours: f(12)
f(12) = 9(12) + 10
f(12) = 108 + 10
f(12) = 118
Bill would work earn $118 if he worked for 12 hours.
