Answer:
56 units long
Step-by-step explanation:
the whole line is 73 units long, and CB is 17 units long. You would subtract 17 from 73 and then you have the missing value which is 56. (or in other words 17 plus what equals 73).
The container that holds the water for the football team is 1/4 full. After pouring in 10 gallons of water, it is 2/3 full. How many gallons can the container hold?
Answer:
[tex]x =24[/tex]
Step-by-step explanation:
From the question we are told that
Amount of water 1/4x
Gallons added 10
Amount of water after addition 2/3x
Where x is a full container
Generally the parameters above gives the equation
[tex]\frac{1}{4}x +10=\frac{2}{3}x[/tex]
Therefore
[tex]\frac{1}{4}x -\frac{2}{3}x =-10[/tex]
[tex]-\frac{5}{12}x =-10[/tex]
[tex]x =\frac{-10}{-\frac{5}{12}}[/tex]
[tex]x =24[/tex]
Therefore the container can hold 24 gallons of water

Answer:
The value of x = 12.
Step-by-step explanation:
We know that two angles are termed as supplementary when the sum of the measure of their angles is 180°.
We also know that a straight line angle measures 180°.
It is clear that the angles 72° and 9x° line on a straight line. Thus, the sum of the measure of their angles is 180°.
Therefore,
9x° + 72° = 180°
9x° = 180° - 72°
9x° = 108
divide both sides by 9
9x/9 = 108/9
x = 12
Therefore, the value of x = 12.

Jeff, Lauren, and Sarah finished their meal, and their total for the three dinners before tax was $21.65. If the tax on their meal was 8.5%, how much was the total cost of their meal with tax? Round to the nearest hundreth.
Answer: The total cost of their meal with tax= $23.49
Step-by-step explanation:
Given: Cost of the three dinners before tax = $21.65
Tax = 8.5%
Tax amount = 8.5% of ( Cost of the three dinners before tax)
= (0.085) x 21.65 [0.085 = 8.5%]
= $1.84025 ≈ $ 1.84
The total cost of their meal with tax = Cost + Tax amount
= 21.65 + 1.84
= $23.49
Hence, the total cost of their meal with tax= $23.49
find f(-10) f(x)=7x-5
Answer:
f(-10) = -75Step-by-step explanation:
F(x) is simply another way of saying y. We are given the x value of -10. We can substitute this in for x and find y.
f(-10) = 7(-10) - 5
f(-10) = -70 - 5
f(-10) = -75

The diagram shows the graph of y = ax + b. Find the values of a and b *
Answer:
The values of a and b are:
a = 2b = 2Step-by-step explanation:
We know that the slope-intercept form of the line equation
y = ax+b
where
a is the slopeb is the y-interceptFrom the diagram of the line graph, we can fetch the two points
(0, 2)(-1, 0)Determining the slope between (0, 2) and (-1, 0)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:2\right),\:\left(x_2,\:y_2\right)=\left(-1,\:0\right)[/tex]
[tex]a=\frac{0-2}{-1-0}[/tex]
[tex]a=2[/tex]
Thus, the value of a = 2
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 2
Thus, the y-intercept b = 2
now substituting a = 2 and b = 2 in the slope-intercept form of the line equation
y = ax+b
y = 2x + 2 ∵ a = 2 , b = 2
Thus, the line of equation is:
y = 2x+2
now comparing with y = ax+b
Here:
a = 2
b = 2
Therefore, the values of a and b are:
a = 2b = 2HELP ASAP!! I WILL MARK BRAINLIEST!! Write an equation for the graph.
Answer:
y = 7/4x
Step-by-step explanation:
All you have to do is find the slope by using the formula change in y divided by change in x of the two points. You can see that y goes up by 14 when x goes up by 8. This means that the slope is 14/8, or 7/4.
The equation would then be y = 7/4x
Which equation describes the line with slope 5 that contains the point (-2,4)?
A. y= 5x +4
B. y = 5x-22
C. y - 5x + 14
D. y = 5x-2
Answer:
C. y=5x+14
Step-by-step explanation:
Solve using this formula: y=mx+b
4 = (5) (-2) + b
4 = -10 + b
+10 +10
14 = b
Then you will plug in what you found for b in:
y=5x+14

Answer:
[tex](4n + 3) - (3 {n}^{2} + 2) \\ = 4n + 3 - 3 {n}^{2} - 2 \\ = - 3 {n }^{2} + 4n + 1 \\ ( - 3 {n}^{2} - 3n) - (1n + 1) \\ - 3n(n + 1) - 1(n + 1) \\ (n + 1)( - 3n - 1) \\ n = - 1 \\ n= \frac{1}{ - 3} [/tex]
Answer:

(4n²-3n+1) is the right answer.In ΔABC, the measure of ∠C=90°, CB = 7, BA = 25, and AC = 24. What ratio represents the cotangent of ∠B?
Answer:
[tex]\frac{7}{24}[/tex]
Step-by-step explanation:
The cotangent of [tex]m\angle B[/tex] can be represented as [tex]\frac{1}{\tan (m\angle B)}[/tex]. Using trig rules for a right triangle, we can write the following equation:
[tex]\tan B=\frac{24}{7}[/tex].
Therefore, the cotangent of [tex]m\angle B[/tex] is:
[tex]\cot B = \frac{1}{\tan B}=\frac{1}{\frac{24}{7}}=\fbox{$\frac{7}{24}$}[/tex].
The ratio of cotangent of angle B is [tex]\frac{7}{24}[/tex]. for understanding check the calcualtiion here ,
From the given information ,
In ΔABC, the measure of ∠C=90°, CB = 7, BA = 25, and AC = 24
Contangent of any angle is equal to adjacent side divide by opposite side
Cotangent of an angle is a relationship found by dividing the length of the side adjacent to given angle by the length of side opposite to the given angle.
The side opposite to angle B is CB and side opposite of angle B is AC
cot (B) = adjacent side / opposite side
[tex]cot(B)=\frac{CB}{AC}[/tex]
CB = 7, BA = 25, and AC = 24
[tex]cot (B)=\frac{7}{24}[/tex]
The ratio of cotangent of angle B is [tex]\frac{7}{24}[/tex]

Emily buys 14 balloons. 3 are red, 4 are white, and the rest are blue. What is the ratio of blue balloons to the total number of balloons? Group of answer choices
Answer:
3:4:7
Step-by-step explanation:
14-(3+4)
=14-7
=7
red:white:blue
3:4:7
Answer:
Step-by-step explanation:
3 + 4 + 7 = 14 which is the total
The blue balloons number 7 because 14 - (3 + 4) = 14 - 7 = 7
So the ratio is 7 blue / 14 (which is the total)
7/14 = 1/2 or 1 to 2

If y varies directly with x and y = -3 when x = 6, find y when x = 14.
We know if y varies directly with x, we get the equation
y ∝ x
y = kx
k = y/x
where k is called the constant of variation.
we are given y = -3 when x = 6
so substitute y = -3 and x = 6 to determine 'k'
k = y/x
k = -3/6 = -1/2
Now we have to find y when x = 14
so substituting x = 14 and k = -1/2 to find y
y = kx
y = -1/2 × 14 = -7
Therefore, the value of y = -7 when x = 14
10) If y is directly proportional to x and y = 4 when x = 3, find x when y = -12.
we are given y = 4 when x = 3
so substitute y = 4 and x = 3 to determine 'k'
k = y/x
k = 4/3
Now we have to find x when y = -12
so substituting y = -12 and k = 4/3 to find x
y = kx
x = y/k
x = [-12] / [4/3] = [-12×3] / [4]
x = -36/4
x = -9
Therefore, the value of x = -9 when x = 3
11)
If y varies directly with x and y = -6 when x = 2, find the constant of variation.
We are given
y = -6
x = 2
so substitute y = -6 and x = 2 in the equation
k = y/x
k = -6/2
k = -3
Therefore, the value of the constant of variation will be:
k = -3
