Answer:
c+d(x)= 180°
Step-by-step explanation:
supplemental angles are supplementary if the sum of their measurements is 180°. each angle is called the supplement of the other.
for instance, in a car, the speedometer and the angles within formed by the needle and the base of the speedometer are supplements of one another.
the measurement of an angle measuring 63° is 180° - 63° = 117°
Answer:
angle D = 180 - x
Step-by-step explanation:
given c=x degree
d =?
In supplementary angles sum of two angles is 180 degree so according to the question
angle c + angle D =180 degree
x + angle D =180
angke D =180 -x

Write the equation of the line which has a slope of -5 and passes through (-4,4). Write the answer in slope-intercept
Answer:
y = - 5x - 16
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 5, then
y = - 5x + c ← is the partial equation
To find c substitute (- 4, 4) into the partial equation
4 = 20 + c ⇒ c = 4 - 20 = - 16
y = - 5x - 16 ← equation of line

Find the volume of the shape with the given dimensions 8 in by 5 in by 3 in
Answer:
V = (8 in)(5 in)(3 in) = 120 in^3
Step-by-step explanation:
The likeliest name for this shape is "rectangular prism." Let's assume that the length, L, is 8 in; the width, W, is 5 in; and the height, H, is 3 in.
Then the volume of this rectangular prism is V = L * W * H, or
V = (8 in)(5 in)(3 in) = 120 in^3
What is the volume of this triangular prism? A triangular prism. The triangular base has a base of 28 centimeters and height of 22.4 centimeters. The height of the prism is 18.1 centimeters. 313.6 506.8 5,676.16 11,352.32
Answer:
The volume of the triangular prism is 5676.16 cm³
Step-by-step explanation:
The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.
Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'
V = Ah' where h = height of prism = 18.1 cm
So, V = bhh'/2
Substituting the values of the variables into the equation for V, we have
V = bhh'/2
V = 28 cm × 22.4 cm × 18.1 cm/2
V = 14 cm × 22.4 cm × 18.1 cm
V = 5676.16 cm³
So, the volume of the triangular prism is 5676.16 cm³
Answer:
5676.16 cm³

Johnny measured a city park and made a scale drawing. The soccer field is 6 millimeters wide in the drawing. The actual field is 60 meters wide. What scale did Johnny use for the drawing?
The scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.
To determine the scale used by Johnny for the drawing, we need to compare the measurements in the drawing to the actual measurements of the soccer field. We can set up a proportion to find the scale.
Let's denote the scale as x (the ratio of the drawing measurements to the actual measurements). According to the information provided, the width of the soccer field in the drawing is 6 millimeters, while the actual width is 60 meters.
We can put up the following proportion using the scale:
6 millimeters / x = 60 meters / 1
We can solve for x by cross-multiplying and then dividing:
6 millimeters * 1 = 60 meters * x
6 = 60x
Dividing both sides by 60:
6 / 60 = x
1 / 10 = x
Therefore, the scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.

Solve the right triangle. Round decimal answers to the nearest tenth.
Answer:
Step-by-step explanation:
take angle A as reference angle
using cos rule
cos A = adjacent/hypotenuse
cos A =10/15
cos A =0.66
[tex]A=cos^{-1} (0.6666)[/tex]
A=48.194
A=48.2
angle A + angle B + angle C =180 degree (being sum of interior angles of a triangle)
48.2 + angle B + 90 =180
138.2 + angle B =180
angle B =180-138.7
angle B =41.8

What is Function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
We have a function,
g(x) = x²
It is a parabola with vertex at (0,0) and the sign is positive then the parabola opens up.
Then, General equation of parabola is
y= a(x - h)² + k
As, the The graph of F(x) opens down that is why it will have negative x²
and vertex at (2, -1)
So, the equation of parabola
y= -1(x - 2)² + (-1)

A bag contains 8 red balls and 6 blue
balls.
Radhika takes three balls at random
from the bag, without replacement.
Calculate the probability that the three
balls are the same colour. *
Answer:
The probability that all 3 balls are red is 18.65%, while the probability that all 3 balls are blue is 7.87%.
Step-by-step explanation:
Since a bag contains 8 red balls and 6 blue balls, and Radhika takes three balls at random from the bag, without replacement, to calculate the probability that the three balls are the same color, the following mathematical operations must be performed:
8 + 6 = 14
14 = 100
8 = X
8 x 100/14 = X
800/14 = X
57.14 = X
100 - 57.14 = 42.86
0.5714 ^ 3 = X
0.1865 = X
0.4286 ^ 3 = X
0.0787 = X
Therefore, the probability that all 3 balls are red is 18.65%, while the probability that all 3 balls are blue is 7.87%.
Two roots of a third degree polynomial function f(x) are –4 and 4. Which statement describes the number and nature of all roots for this function?
f(x) has three imaginary roots.
f(x) has three real roots.
f(x) has two real roots and two imaginary roots.
f(x) has three real roots and one imaginary root.
Answer:
Step-by-step explanation:
A third degree polynomial has a total of three roots, real and imaginary combined.
If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
Answer:

In stage 2 of a rocket's takeoff, the speed of the rocket increases at a rate of 4.3% per minute. The speed of the rocket at the beginning of stage 2 was 5,000 kilometers per hour. Its speed at the end of Stage 2 will be 25,000 kilometers per hour.
If t is the time, in minutes, from the beginning of stage 2, which equation could be used to determine how long it will take for the speed of the rocket to reach 25,000 kilometers per hour, assuming it increases at the same rate for all of stage 2?
A.
5,000 = 25,000(0.043)t
B.
5,000 = 25,000(0.957)t
C.
25,000 = 5,000(1.043)t
D.
25,000 = 5,000(1.43)t

Be descriptive and give examples. Make sure you include the data set (the group of numbers) you will be working with. Be sure to use complete sentences. Be creative!

1. The mean is the average of a data set.
2. The mode is the most common number in a data set.
3. The median is the middle of the set of numbers.
Of the three, the mean is the only one that requires a formula. I like to think of it in the other dictionary sense of the word (as in, it’s mean as opposed to nice!). That’s because, compared to the other two, it’s not as easy to work with.
