Answer:
The answer is "8".
Step-by-step explanation:
Let the number are a, b, c then value is as follows:
a= 3
b= 5
c= 7
The addition of equation ⇒ a+b+c =15....................(i)
multiply by the value ⇒ 3a + 5b + 7c = 75 ...............(ii)
let b= 15-a-c which subtract from equation (ii)
equation:
⇒ 3a + 5b + 7c = 75
⇒ 3a + 5(15-a-c) + 7c = 75
⇒ 3a +75-5a-5c+7c = 75
⇒ 3a -5a-5c+7c = 75-75
⇒ -2a + 2c = 0
⇒ 2(c-a) = 0
⇒ (c-a) = 0
⇒ c=a
if we put value in between 0 to 7 from it satisfies the two equations, with c=a and b = 15 - a - c. So, the correct answer is 8.

Answer:
24%
Step-by-step explanation:
You first add the boys because you know you only look at the boys not the girls. You get the answer 233. Then you divide the number of boys who chose Niagra Falls which is 56 over 233. You will get a decimal. You then multiply the decimal by 100 to get your answer. The answer would be 24.0343348% which would round to 24%.

What’s the value of x in a triangle x top right 45 top left 98 bottom
Answer:
The value of x is 37°.
Step-by-step explanation:
Given that the total angles in a triangle is 180°. In order to find the x value, you have to substract 98° and 45° from 180° :
[tex]x + 98 + 45 = 180[/tex]
[tex]x = 180 - 98 - 45[/tex]
[tex]x = 37[/tex]
Answer: 37
Step-by-step explanation:
If you add in all numbers inside the triangle, it should be equal to 180 degrees meaning x + 98 + 45 = 180.
To solve the unknown, we must first add in the numbers:
x + 143 = 180
To get the variable by itself, we must subtract 143 to both sides which gives us 37 degrees.
Now that we know that x is equal to 37, we should make sure it is the right answer, to do that, we need to replace x with 37:
37 + 98 + 45 = 180
By adding in all the numbers, we should get 180.

Step-by-step explanation:
Right triangle ABC is shown.
Triangle A B C is shown. Angle A C B is a right angle and angle C B A is 50 degrees. The length of A C is 3 meters, the length of C B is a, and the length of hypotenuse A B is c.
Which equation can be used to solve for c?
sin(50o) = StartFraction 3 Over c EndFraction
sin(50o) = StartFraction c Over 3 EndFraction
cos(50o) = StartFraction c Over 3 EndFraction
cos(50o) = StartFraction 3 Over c EndFraction
Answer:
sin(50deg) = 3/c
Step-by-step explanation:
Applying the trigonometry ratio, SOH, the equation that can be used to solve for c is: sin (50°) = 3/c.
Trigonometry RatiosTo solve a right triangle, any of the ratios, SOH CAH TOA, can be applied.
Thus, given right triangle ABC, where:
angle ACB = right angleangle CBA (∅) = 50 degrees (reference angle)AC = 3 m (opposite)AB (c) = hypotenuse = ?Apply SOH:
sin ∅ = opp/hyp
Substitutesin (50°) = 3/c
Therefore, applying the trigonometry ratio, SOH, the equation that can be used to solve for c is: sin (50°) = 3/c.

This sculpture is made of solid onyx and has a square hole through the middle. How much onyx was used to make the sculpture?
The volume of the sculpture is in.3.
To find the volume of the onyx used, we have to find the volume of the larger figure and then subtract the volume of the smaller figure from it.
The volume of onyx used is equal to 128in^3
Volume of the larger figureLet's proceed to multiply through the length, width and height of the figure to determine the volume.
[tex]volume = length * width * height \\volume = 8 * 8 * 3\\volume = 192in^3[/tex]
The volume of the larger figure is 192in^3
Let's calculate the volume of the square hole
[tex]volume of square = (length)^3\\volume of the square = 4^3 \\volume of the square = 64in^3[/tex]
Data;
Volume of larger figure = 192in^3volume of the square hole = 64in^3Let's subtract now and calculate the volume of onyx used

For the given angle measure, find the measure of a supplementary angle and the measure of a complementary angle, if possible. If not possible, type the word none in lowercase letters in the box.
The given angle measure is 27º
Answer:
A complementary angle is 63 degrees and supplementary angle is 153 degrees.
Step-by-step explanation:
Complementary angle:
A complementary angle adds up to 90 degrees, so you have to subtract 27 from 90. 90-27=63
Supplementary angle:
A supplementary angle adds up to 180 degrees, so you have to subtract 27 from 180. 180-27=153
Answer:
The supplementary angle is
153°.
The complementary angle is
63°.

Lee has a bag with 500 quarters. Some are the older eagle quarters, and others are the newer state quarters. She pulls out 10 quarters at random. Four are eagle quarters, and 6 are state quarters. Based on this sample, how many of the quarters in the full bag were likely to be eagle quarters? 400 200 100 300
Answer:
400
Step-by-step explanation:
The number of eagle quarters likely to be in the bag is 200.
Option B is the correct answer.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of quarters = 500
Out of the 10 quarters.
Eagle quarters = 4
This means,
Percentage of eagle quarters,
= 4/10 x 100
= 40%
Now,
40% of 500 quarters.
= 40/100 x 500
= 200
Thus,
The full bag is likely to have 200 eagle quarters.

The following function is continuous at all points in the domain of real numbers. What is the value of n?
f(x)= 2x+2, if x > n
4x, if x [tex]\leq[/tex] n
A. -1
B. 0
C. 1/2
D.1
Answer:
D. 1Step-by-step explanation:
To solve this problem, we just need to find the common point of these linear function, beacuse they form a piecewise function which is continuous according to the problem, that means they are related by one common point.
Let's solve the following expression [tex]f(x)=g(x)[/tex], where [tex]f(x) =2x+2[/tex] and [tex]g(x)=4x[/tex]. So,
[tex]2x+2=4x\\2=4x-2x\\2x=2\\x=1[/tex]
Which means [tex]n=1[/tex], that is, if the n is greater than 1, then the function is defined by [tex]f(x)[/tex], if the n is least or equal than 1, then the functioni is defined by [tex]g(x)[/tex]
Therefore, the right answer is D.
Answer:
1. A, -1
2. D, 1
3. B, It is discontinuous because there is a value a for which f(a) is not defined 4. D, It is discontinuous because there is a value a such that lim f(x) does not exist
