Answer:
2 5/12
Step-by-step explanation:
(5 + 1/4) - (2 - 5/6)
5 - 2 = 3
(1/4 x 3/3) - (5/6 x 2/2) = 3/12 - 10/12 = -7/12
3 - 7/12 = 2 5/12

Answer:
x = 72° , y = 54°
Step-by-step explanation:
x and 108° are adjacent angles on a straight line and sum to 180°
x + 108° = 180° ( subtract 108° from both sides )
x = 72°
The vertex of the triangle on the left is vertically opposite x and is congruent
vertex = 72°
The sum of the 3 angles in the triangle = 180° , that is
y + y + 72° = 180°
2y + 72° = 180° ( subtract 72° from both sides )
2y = 108° ( divide both sides by 2 )
y = 54°
Answer:
so the answer is y=54°

Last year, a gardening store ordered 530,570 potted plants. This year, they ordered 424,456 potted plants. What is the percent of decrease in the number of potted plants ordered annually?
Answer:
last year = 530570
this year = 424456
decreased plants = 530570-424456 = 106114
decreased percent = 106114÷530570×100%
= 20%
therefore 20% is the decrease precent in the number of potted plants ordered anually
one day 18 teachers were sick with the flu. if this were 12% of the total number of teachers how, many teachers were there altogether?
Answer:
Total teachers = 150
Step-by-step explanation:
Let total teachers = x
12% of x = 18
[tex]\dfrac{12}{100}*x = 18\\\\\\x= 18*\dfrac{100}{12}=18*\dfrac{25}{3}\\\\\\x = 6*25\\\\x = 150[/tex]

12%.x = 18
x = 18 × 100/12
x = 1.800/12
x = 150
What is the amount received at the end of the period on investing $1000 for 2 years at 5% per annum compound interest?
Answer:
$1102.50
Step-by-step explanation:
The appropriate compound interest formula is
A = P(1 + r)^t, where P is the principal ($1000), t is the number of years, and r is the interest rate as a decimal fraction.
Here A = $1000(1 + 0.05)^2 = $1000(1.05)^2 = $1102.50
Of the 405 students who took the test,
162 of them passed. Write a ratio in
simplest form for the number of
students who passed the test to the
number of students who took the test.
Answer:
5 : 2
Step-by-step explanation:
ivide both terms by the GCF, 81:
405 ÷ 81 = 5
162 ÷ 81 = 2
The ratio 405 : 162 can be reduced to lowest terms by dividing both terms by the GCF = 81 :
405 : 162 = 5 : 2
Therefore:
405 : 162 = 5 : 2

Answer:
I think the answer is OP=PQ
The correct equation will be OP = PQ.
What is midpoint?In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.
Given that, there is a line segment, OQ, and the point P is the midpoint of the line segment,
We need to determine the relation between OP and PQ,
So, according to the definition of midpoint, the midpoint divides the segment into two equal halves,
Therefore,
OP = PQ
Hence the correct equation will be OP = PQ.

Miranda has $5.05 in dimes and nickel in her car. The number of nickels is seventeen more than the number of dimes. How many of each type of coin does she have?
Answer: 28 Dimes and 45 Nickles
Step-by-step explanation:
See attachment.
Let the number of dimes and nickles be D and N. Use the unit of pennies.
We are told: N = D + 17
The total of 505 cents is the sum of 10D and 5N : 10D + 5N = 505
Use N = (D+17) in the above equation.
10D + 5(D+17) = 505
15D + 85 = 505
15D = 420
D = 28
Since N = D + 17, N = 45
Check:
10D + 5N = 505 ?
10(28) + 5(45) = 505
280 + 225 = 505 It works.
Find the measures of the interior angles of the triangle.
Answer:
∠ A = 59°, ∠ B = 48° , ∠ C = 73°
Step-by-step explanation:
The interior angles of a triangle sum to 180°
sum the 3 angles and equate to 180
x + x - 11 + 73 = 180
2x + 62 = 180 ( subtract 62 from both sides )
2x = 118 ( divide both sides by 2 )
x = 59
Then
∠ A = x = 59°
∠ B = x - 11 = 59 - 11 = 48°
∠ C = 73°
Answer:
<A = 149*
<B = 138*
<C = 73*
Step-by-step explanation:
There are 360* total inside a triangle.
We subtract 73 from 360 to find the combined number of both angles a and b.
360-73 equals 287, so we know that both angles a and b add up to equal 287.
Since angle a equals x and angle b equals x - 11, we would combine the two expressions to find x. When we find x, it will allow us to know what both angles a and b equals to. So we combine x and x- 11, set it equal to 287, and solve for x.
x + x - 11 = 2x-11.
287 = 2x - 11
(Add eleven to both sides)
298 = 2x (divide both sides by two)
X = 149
Since angle a equals x, we know that angle a Is 149*.
And since angle b is x - 11, we take 149, subtract it by 11, and we get 138.
Find the missing length.

X
The missing length of the given triangle divided into two right-angled triangle is 24.
The ratio 60:36:x is a ratio of 2:1:x. This means that the ratio of the lengths of the three segments is 2:1:x. The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.
Here is the solution in more detail:
The ratio 60:36:x can be written as 2:1:x.
This means that the ratio of the lengths of the three segments is 2:1:x.
The first segment has a length of 60, so the second segment must have a length of 1/3 * 60 = 24.
Therefore, the missing length is 24.

Sketch the graph of y = (x - 2)2 - 16, then select the graph that corresponds
to your sketch.
A. Graph A
B. Graph B
C. Graph C
D. Graph D
Answer:
B) Graph B
Step-by-step explanation:
The quadratic equation in vertex form is represented by: y = a(x - h)² + k, where:
(h, k) = vertex
x = h : axis of symmetry
a = indicates a reflection in the x-axis; it also determines the graph's vertical stretch or shrink.
a > 0 the graph opens up.a < 0: the graph opens down.h = indicates a horizontal translation.
k = indicates a vertical translation.
Given the given quadratic equation, y = (x - 2)² - 16:
The vertex occurs at point, (2, -16), and a = 1. Since the value of a is positive, then it implies that the graph opens upward, and the vertex is its minimum point. The axis of symmetry occurs at h = 2.
To determine another point to use as a reference (and also for graphing) is solving for the equation's y-intercept, which is the point where it crosses the y-axis (where x = 0).
Y-intercept: set x = 0:
y = (x - 2)² - 16
y = (0 - 2)² - 16
y = (-2)² - 16
y = 4 - 16
y = -12
Therefore, the y-intercept is (0, -12).
Therefore, the graph that matches these given descriptions is Graph B.
Attached is the graphed quadratic equation where it shows the vertex, y-intercept, and the axis of symmetry.

Step-by-step explanation:
To find the prime factorization of a number, start by dividing the number by each prime number that you can divide by as many times as possible, starting with the smallest prime number and moving up. Then move on to the next prime number. The last division must give a quotient of 1. Then the prime factorization is the product of all the prime factors you divided the number by.
Here's how you use this method with 180.
Here are the first 10 prime numbers:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29
Start by trying to divide by 2. 180 is divisible by 2.
180/2 = 90 90 is divisible by 2.
90/2 = 45 45 is not divisible by 2, so now try 3.
45/3 = 15 15 is divisible by 3.
15/3 = 5 5 is prime, so it is divisible by 5.
5/5 = 1 The divisors in bold are the prime factors of 180.
180 = 2 × 2 × 3 × 3 × 5
180 = 2² × 3² × 5
Answer: 5
Answer:

Step-by-step explanation:
180

180 = 2 × 3 × 3 × 2 × 5
2² × 3² × 5
NOTE: The numbers underlined in the factor tree are prime numbers.
Also, 2²is 4 (2 × 2)
3² is 9 (3 × 3)
4 × 9 = 36
36 × 5 = 180
