Answer:
x = 65, y = 63
Step-by-step explanation:
∠ EGA = ∠ HBG = 52° ( corresponding angles )
ED is a straight angle, thus
52 + y + 65 = 180, that is
y + 117 = 180 ( subtract 117 from both sides )
y = 63
-------------------------------------
∠ HGB = y = 63° ( vertical angles )
The sum of the 3 angles in a triangle = 180°, thus
x + 63 + 52 = 180
x + 115 = 180 ( subtract 115 from both sides )
x = 65
x/2−5=−12
I need to know how to get the answer to what X is
Answer:
-14
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x/2-5=-12
1/2x+-5=-12
1/2x-5=-12
Step 2: Add 5 to both sides.
1/2x-5+5=-12+5
1/2x=-7
Step 3: Multiply both sides by 2.
2*(1/2x)=(2)*(-7)
x=-14
Answer:
-14
Step-by-step explanation:
x/2 = -12 + 5 << add both sides by 5
x/2 = -7 << Combine -12 + 5
x = -14 << Multiply both sides by 2
This revolves around the idea of inverse operations
To get x by itself we needed to bring the other numbers to the other side of the equation.
Inverse operations is bring the numbers to the other side by doing the opposite operation it shows.
ex: if the number is +5 on one side, it will be -5 on the other
Hope this helps!

Jada rewrites 5•3^x as 15x. Do you agree with Jada that these are equivalent expressions? Explain your reasoning. Help me pleasee
Answer:yes
Step-by-step explanation:
5*3=15
5*3x=15x
The expression 15x is not the equivalent of the expression 5•3ˣ.
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
It is a relation of the form y = aˣ in mathematics, where x is the independent variable
Jada rewrites 5•3ˣ as 15x.
We do not agree with Jada that these are equivalent expressions because she made the mistake.
As per the given obtained expression, we can see that here write 15 as the coefficient of variable x which is actually the power of an argument. the original expression was an exponential function that has 3 representing the base. thus, it cannot be multiplied the 5 by 3.
Thus, the expression 15x is not the equivalent of the expression 5•3ˣ.

Answer:
339.12 squared (for surface area)
Step-by-step explanation:
radius=6
area of the circles is, 6*6= 36 * 3.14= 113.04
there are 2 circles so we multiply that by 2 to get 226.08
now to find the perimeter of a circle it is the radius * pi, so that would be 6*3.14= 18.84 now we have a height of 6 so we multiply that by 6 and get 113.04 now add up all our numbers and get 339.12
What is the least common multiple of the two denominators?
6/8 4/32
A.18
B.12
C. 8
D.32
Answer:
d.32
Step-by-step explanation:
To get the Least Common Multiple (LCM) of 8 and 32 we need to factor each value first and then we choose all the factors which appear in any column and multiply them:
8: 222
32: 22222
LCM: 22222
The Least Common Multiple (LCM) is: 2 x 2 x 2 x 2 x 2 = 32
The least common multiple is = 32
The denominators are 8 and 32.
The multiples of 8 are = 8, 16, 24, 32, 40, ....
The multiples of 32 are = 32, 64, ....
So the least common multiple is = 32

Find the surface area and volume of the figure.
Answer:
Surface area: 310.86 sq ft
Step-by-step explanation:
First, find the surface area of the cylinder. This can be found by finding the area of the circle at its base, and then the area of its mid-region.
The area of the circle can be found using the formula: a = pi(r^2). r stands for radius, which is 3 in this problem. 3^2 equals 9, which, multiplied by pi (3.14), equals 28.26.
The area of the cylinder's mid-region is equal to the circumference of the circle multiplied by the height of the cylinder. The circumference of the circle is equal to c = 2pi(r), or in this case: 18.84. Now, multiply this value by the height to get 226.08 as the area of the mid-region.
Lastly, find the surface area of the sphere. This can be found using the equation a =4πr^2. r is, again, radius, which in this problem can be represented by 3. The surface area of a sphere with a radius of 3 is 113.04. However, this figure only shows half a sphere, which can be found by dividing 113.04 in half. This gets you 56.52.
Now, simply add all the areas together to get the total surface area!

The function which represents the graph given is f(x) = (x - a)²(x - b)⁴.
What are Polynomials?Polynomials are expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.
Given is a graph of a function.
The options f(x) = x(x - a)³(x - b)³ and the option f(x)=x(x - a)⁶(x - b)² is not possible since x = 0 is not a root of the given graph.
That is the graph does not pass through the point (0, c) for any c.
Remaining options are f(x) = (x - a)²(x - b)⁴ and f(x) = (x - a)⁵(x - b).
We know that, the graph of a polynomial function always touch the X axis at zeroes with even multiplicities.
So here multiplicity will be even.
So the correct one is f(x) = (x - a)²(x - b)⁴.

d.1057
Answer:
a. 1057 is not a perfect square
b. 23453 is not a perfect square
c. 2304 is a perfect square
d. 1057 is not a perfect square
Step-by-step explanation:
A perfect square is a number x where the square root of x is a number a such that a² = x and a is an integer. For example, 4, 9 and 16 are perfect squares since their square roots, 2, 3 and 4, respectively, are integers.
Solve for the zeros of the quadratic function f(x) = 9.2 + 6x +1. Write the answer as a fraction.
Answer:
x = -1.7, or x = -17/10
Step-by-step explanation:
f(x) = 9.2 + 6x + 1 is a linear function and as such (and because the slope is not zero) has only one solution. Combining like terms, we get
f(x) = 10.2 + 6x = 0 (you must set this equal to zero if solving for zero(s).
Then 6x = -10.2, and x = -1.7, or x = -17/10
45% of all 1st graders at Sierra Elementary School are female students. This year there are 54 female 1st graders at Sierra Elementary School. How many 1st graders are there at Sierra Elementary School this year?
Answer:
There are 120 1st graders at Sierra Elementary School this year
Step-by-step explanation:
Let n represent the total number of 1st graders at Sierra Elementary School
Since 45% of all 1st graders at Sierra Elementary School are female students and this year there are 54 female 1st graders, 45% of n is equal to 54
→ n([tex]\frac{45}{100}[/tex]) = 54
→ 45n = 5400
→ n = 120
Answer:
number of first grader at Sierra elementary school = 120
Step-by-step explanation:
The question says 45% of 1st graders at Sierra Elementary school are female student . This year there are 54 female 1st graders at Sierra Elementary school .The number of 1st graders at Sierra elementary school can be calculated below .
Let
the number of 1st grader = a
45 % of a = female population
This year the female 1st graders at the Sierra elementary school are 54. This can represented as follows
45% × a = 54
45/100 × a = 54
45a/100 = 54
cross multiply
45a = 5400
divide both sides by 45
a = 5400/45
a = 120
number of first grader = 120

Answer:
$30
Step-by-step explanation:
If $25 is 100%,
$2.5 is 10%
$0.25 is 1%
$3.75 is 15%
$0.75 is 3%
Then add $25, $3.75 and 0.75 which is also equivalent to 100%+15%+3%=29.5 and if you rounded it up to the nearest cent it is 30

A coin is tossed and a die is rolled. What is the probability that a tail was tossed and an even number was rolled?What is the probability that a head was tossed and a number larger than 4 was rolled?
Please Show Work! Thanks!
Answer:
First problem: 1/4 chance
Second problem: 1/6 chance of happening
Step-by-step explanation:
To find the probability we need to multiply the chance of each separate thing happening by each other in each example.
In the first example we have a 1/2 chance that a tail was tossed and 3/6 chance that an even number was rolled.
[tex]\frac{1}{2} *\frac{3}{6} = \frac{3}{12} =\frac{1}{4}[/tex]
So in the first example we have 1/4 chance of happening or 0.25

A jar contains 5 popsicle sticks, numbered 1-5. A stick is drawn, then a letter in the word SPRING is chosen at random. What is the probability the number is greater than 2, then P?
Answer:
10% probability that the number is greater than 2, then P
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Event A: Number greater than 2.
Event B: Letter P.
These events are independent, so:
[tex]P(A \cap B) = P(A) \times P(B)[/tex]
P(A)
There are 5 numbers.
3, 4 or 5, that is, 3 numbers greater than 2.
3/5 = 0.6. So P(A) = 0.6.
P(B)
6 letters, one of which is P. So
P(B) = 1/6 = 0.1667.
What is the probability the number is greater than 2, then P?
[tex]P(A \cap B) = P(A) \times P(B) = 0.6 \times 0.1667 = 0.1[/tex]
10% probability that the number is greater than 2, then P
