What is the slope of the line that contains the
points (-6, 1) and (4,4)?
Answer:
3/10
Step-by-step explanation:
y2 - y1 / x2 - x1
4 - 1 / 4 - (-6)
3/ 10
Answer:
Step-by-step explanation:
y1-y2
--------
x1-x2
so
and (x1,y1) and (x2,y2) are those points so plug it in
(1-4)/(-6-4) so that simplifies to -3/-10 so just 3/10 is the slope.
Hope this helps!
Find the length of arc XW. Round your answer to the nearest hundredth.
Answer:
15.08 m
Step-by-step explanation:
The angle XZW :
XZW + 108° = 180°
XZW = 180° - 108°
XZW = 72°
Length of an arc = θ / 360 * πd
d = diameter = XV = 24
Length of arc XW = (72/360) * π * 24
Length of arc XW = 15.0796
Length of XW = 15.08 m
Answer:
15.08
Step-by-step explanation:
Two square pyramids are similar.
The sides of the bases are 4 cm and
12 cm. The height of the smaller
pyramid is 6 cm. Find the height of
the larger pyramid.
Answer:
18 cm
Step-by-step explanation:
Since the pyramids are similar then the ratio of corresponding sides are equal, that is
12 ÷ 4 = 3
Then the height of the larger pyramid is 3 times the height of the smaller.
height of larger pyramid = 3 × 6 = 18 cm

Answer:
Area = B x H + L (sum of sides of triangle)
= 9 x 12 + 10 (12 + 15 + 9)
= 108 + 360
=[tex]468in^2[/tex]
Either your options are wrong or question is to find lateral surface.
Lateral Surface area = ( a + b + c) x H , where a, b , c are sides of the triangle.
Lateral Surface Area = (12 + 15 + 9) x 10

qualitative Or quantitative?
Answer:
It is Quantitative.
Step-by-step explanation:
Quantitative data is information about quantities; information that can be measured with numbers.
Qualitative data describes qualities or characteristics; information collected using questionnaires, interviews, or observation, and frequently appears in narrative form.
Examples:
It is 25° Celcius today. - Quantitative
I drooled after smelling freshly baked cookies. - Qualitative
Tips:
Think of Quantitative as Quantity; numbers.
Think of Qualitative as Quality; description/characteristics.

b) Work out the input when the output is 42
(2)
D &
Answer:
(a) Output = 37
(b) Input = 9
Step-by-step explanation:
Given
[tex]y =x5 - 3[/tex]
Solving (a): Output, when input = 8
This means that, we solve for y when x = 8
So, we have:
[tex]y =x5 - 3[/tex]
[tex]y =8*5 - 3[/tex]
[tex]y =40 - 3[/tex]
[tex]y = 37[/tex]
Solving (b): Input, when output = 42
This means that, we solve for x when y = 42
So, we have:
[tex]y =x5 - 3[/tex]
[tex]42 = x5 - 3[/tex]
Collect like terms
[tex]x5 = 42 + 3[/tex]
[tex]x5 = 45[/tex]
Divide both sides by 5
[tex]x = 9[/tex]
Ivan draws PQR on the coordinate plane.
What is the perimeter of PQR? Round to the
nearest unit.
Answer:
Perimeter of PQR = 37 units (Approx.)
Step-by-step explanation:
Using graph;
Coordinate of P = (-2 , -4)
Coordinate of Q = (16 , -4)
Coordinate of R = (7 , -7)
Find:
Perimeter of PQR
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between PQ = √(-2 - 16)² + (-4 - 4)²
Distance between PQ = 18 unit
Distance between QR = √(16 - 7)² + (-4 + 7)²
Distance between QR = √81 + 9
Distance between QR = 9.48 unit (Approx.)
Distance between RP = √(7 + 2)² + (-7 + 4)²
Distance between RP = √81 + 9
Distance between RP = 9.48 unit (Approx.)
Perimeter of PQR = PQ + QR + RP
Perimeter of PQR = 18 + 9.48 + 9.48
Perimeter of PQR = 36.96
Perimeter of PQR = 37 units (Approx.)

Which answer choice correctly represents an algebraic expression for the quotient of a number and 9?
A. 9j
B. j ÷ 9
C. j – 9
D. 9 + j
=========================================================
Explanation:
The quotient is the result after a division problem.
As another example, we would say that 9 is the quotient of 27 and 3 because 27 ÷ 3 = 9
We can use the slash symbol / to mean division. So we could say 27/3 = 9
Going back to the answer, we could rewrite j ÷ 9 as j/9
The order is important. This means j ÷ 9 is different from 9 ÷ j which represents "the quotient of 9 and j".

Omar compra una bicicleta, que tiene un descuento del 75%. Si el precio que pago es de Q 70.00. ¿Cuál fue el precio original?
Answer: Por ejemplo, un televisor podría costarle originalmente $ 5000. Determine el porcentaje de descuento: en nuestra tienda de ejemplo, todo tiene un 75% de descuento. La suma que queda en su bolsillo, sus ahorros, es simplemente estos dos valores multiplicados entre sí: 75% * $ 5000 = 0,75 * $ 5000 = $ 3750.

The number of patients treated at Dr. Frank's dentist office each day was recorded for nine days: 18,
19, 19, 4, 14, 8, 22, 3, 1. Using the given data, find the mean for this sample.
A. 12
B.19
C. 29
D. 14
Answer: 12
Step-by-step explanation: The mean is basically the average. So, start by lining up the numbers from smallest to largest. 1, 3, 4, 8, 14, 18, 19, 19, 22. Then, add them all together. You get 108. Then, divide 108 by the number or numbers in the data set, which in this case is 9. So 108 divided by 9 = 12. Your answer is A. --> 12

Which is closest to the volume of the figure shown below?
7 mi
2 mi
351.9 cubic mi.
Ob
117.3 cubic mi.
Ос
29.3 cubic mi.
Od
7.3 cubic mi.
Answer:
c. 29.3 cubic mi
Step-by-step explanation:
Applying,
V = πr²h/3.............. Equation 1
Where V = volume of the cone, r = radius of the circular base, h = height of the cone, π = pie
From the diagram,
Given: h = 7 mi, r = 2 mi
Constant: π = 3.14
Substitute these values into equation 1
V = 3.14(7×2²)/3
V = 29.3 cubic mi
Hence the right answer is c. 29.3 cubic mi
Which of the following is the converse of the statement "If it is snowing,then
it is my birthday"?
O A. If it is not my birthday, then it is snowing.
O B. If it is my birthday, then it is snowing.
C. If it is not my birthday, then it is not snowing.
D. If it is my birthday, then it is not snowing.
Answer:
B)
Step-by-step explanation:
to get the converse, interchange the hypothesis and conclusion
in this case the hypothesis is "if it is snowing" and the conclusion is "then it is my birthday"
Converse would then be "If it is my birthday, then it is snowing"
My nephew, Oliver, got a new Lego set. He has decided to build it with his friend, Josie. It took them 6 hours to build together. If Oliver is half as fast as Josie, how long would it take Josie to build this Lego set alone?
Answer:
4 hours
Step-by-step explanation:
If it took them together with a total of 6 hours and Oliver is half as fast meaning Jose is faster it will take Jose 4 hours.
A simple equation is
6= 4+2
And the 2 would be Oliver since Oliver is half as fast.

Step-by-step explanation:
A restaurant customer left $3.50 as a tip. The tax on the meal was 7% and the tip was 20% of the cost including tax.
Answer:
17.50
Step-by-step explanation:
you really don't need to know the tax amount.
20% of x = 3.50
(20/100) x = 3.50 Divide top and bottom of the left number by 20
(20÷20) / (100÷20) * x = 3.50
(1/5) x = 3.50 Multiply both sides by 5
x = 3.50 * 5
x = 17.50
The meal cost 17.50
