Daniel is a singer, and he promises his agent that he will give him a 25% commission based on what he makes from a show. After paying the agent, Daniel takes home $120. Use the diagram to answer the following questions.
Daniel’s agent made
.
Daniel and the agent made a total of
from the show.
Answer:
Amount in Blank total = $160
Amount of money Daniel’s agent made = $40
Amount of money Daniel and the agent made
from the show = $160
Step-by-step explanation:
this question is based on the calculation of percentages
so,
it is is given in the question that -
Daniel is a singer, and he promises his agent that he will give him a 25% commission based on what he makes from a show.
After paying the agent, Daniel takes home = $120
so,
let 'x' is the total amount of money that Daniel earned form the show
it is also given that Daniel promised to give 25 % to his agent from what he earned from the show
so, percentage of money left to the Daniel is
100-25 = 75%
therefore according to the question,
75percent of the x = $120
75/100×(x) = 120
3/4×(x) = 120
3x = 120×4
3x = 480
x = $160
so the total amount of money Daniel earned from the show is $160
Now we know that Daniel’s agent made 25% of the total amount of money earned from the show
therefore
25percent of 160 = Daniel’s agent made
25/100 ×160 = Daniel’s agent made
$40 = Daniel’s agent made
so the amount of money earned by Daniel’s agent made is $40

The velocity of a particle can be modeled by the function v(t)=1/10(3t-8)^3+2. Which graph accurately shows the velocity of the park or at any time, t?
The graph that accurately shows the velocity of the park or at any time is as shown in the attached image.
How to draw a function Graph?Velocity is defined as the rate of change of position of object with respect to time. Velocity is also defined as the speed of an object moving in a definite direction.
Velocity is a vector quantity and so it has both magnitude and direction. Its' SI unit is in meters per second.
The velocity of a particle is modeled by the function;
v(t) = ¹/₁₀(3t - 8)³ + 2
The given velocity function is cubic function and as such the attached graph shows the velocity of the particle at any time.

An isosceles triangle is one with two equal-length sides. The ΔBCD is an isosceles triangle.
What is an isosceles triangle?
An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.
Given ΔABC is an isosceles triangle with side AB = AC. Therefore, as per the base angle theorem,
∠A = ∠C = 36°
Also, in ΔABC, the sum of the angles can be written as,
∠ABC + ∠BAC + ∠BCA = 180°
∠ABC + 36° + 36° = 180°
∠ABC = 108°
For ∠ABC we can write,
∠ABC = ∠ABD + ∠CBD
108° = 72° + ∠CBD
∠CBD = 36°
Now, in ΔBCD, the measure of ∠CBD and ∠DCB both equals to 36°. Therefore, we can write, that the ΔBCD is an isosceles triangle.

Answer:
[tex]-\frac{1}{2} \vec {c}[/tex]
Step-by-step explanation:
Look at the component form of each vector.
Note that vector c is <4,4> and vector d is <-2,-2>
If one imagined the line that contained each vector, the line for both would have a slope of 1, because [tex]\frac{4}{4}=1=\frac{-2}{-2}[/tex]
Since they have the same slope they are parallel, but since they are in opposite directions, we often call them "anti-parallel" (simply meaning parallel, but in opposite directions).
If two vectors are parallel, one vector can be multiplied by a scalar to result in the other vector. This means that there is some number "k", such that [tex]k \vec{c} = \vec {d}[/tex], or equivalently, [tex]kc_x=d_x[/tex] and [tex]kc_y=d_y[/tex].
If [tex]kc_x=d_x[/tex] and [tex]kc_y=d_y[/tex], we just need to substitute known values and solve for k:
[tex]kc_x=d_x\\k(4)=(-2)\\k=\dfrac{-2}{4}\\k=-\frac{1}{2}[/tex]
Double checking that k works for the y-coordinates as well:

5 14/15 on a number line rounded to the nearest whole number or half.
PLEASE HELP ME!!!!! I NEED HELP
Answer:
Step-by-step explanation:
Here we will show you step-by-step how to get the solution to: "What is 5/14 rounded to the nearest whole number?"
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
5 / 14 = 0.3
Then, we round to the nearest whole number using the following rules:
If the number to the right of the decimal point is .5 or higher, then add 1 to the left of the decimal point.
If the number to the right of the decimal point is less than .5, then leave the number to the left of the decimal point as is and remove the digit to the right of the decimal point.
.4 is less than .5. Thus, we leave the number to the left of the decimal point as is and remove the digit to the right of the decimal point.
5/14 rounded to the nearest whole number is therefore:
0
Please help! To solve the equation 1.75n = 7 for n, what operation must be applied to both sides in order to isolate the variable n?
Answer:
C
Step-by-step explanation:
1.75n = 7 ( to isolate n divide both sides by 1.75 )
n = [tex]\frac{7}{1.75}[/tex] = 4
Answer:
c.) Divide by 1.75
Step-by-step explanation:
Given equation:
⇒ 1.75n = 7
Here the coefficient of n which is 1.75 needs to be removed. There is only one way of doing that - by dividing both sides by 1.75.
When done so:
⇒ 1.75n/1.75 = 7/1.75
⇒ n = 4

find the size of unknown angle
Answer:
x° = 75
(x + 30)° = 105°
Step-by-step explanation:
supplementary angle is two angles that sum is 180°
x° + (x + 30)° = 180°
2x + 30 = 180°
2x + 30 - 30 = 180 - 30
2x = 150
2x / 2 = 150 / 2
x° = 75
plug in 75,
75 + 30 = 105
check: 75 + 105 = 180
Answer: 75 degrees
Step-by-step explanation:
Do you see how both sides of the angle come together to form the straight line seen at the bottom? This means that these are supplementary angles.
Supplementary Angles: Both sides have to add up to a total of 180 degrees.
With this, form an equation: x+(x+30)= 180
Get rid of the parenthesis:
x+x+30= 180
Combine like terms.
2x+30= 180
2x= 180-30
2x= 150
x= 150÷2
x= 75
Checks:
x+x+30= 180
75+75+30= 180
You can also check using the equation in its simplified form: 2x+30= 180.
2x+30=180
2(75)+30=180
150+30=180
Hence x=75
