What is the value of the missing angle (x+15)
Answer:
x = 70
Step-by-step explanation:
The total interior angle in a square, even with not a perfect square, adds to 360
Set your formula up as
360 = (x+15) + x + 115 + 90
360 - 115 - 90 - 15 = 2x
140 = 2x
140/2 = x
70 = x
A bag contains exactly 50 coins. The coins are either worth 10 cents, 20 cents or 50 cents and there is Atleast one of each. The total value of the coins is $10. How many different ways can this occur?
Answer:
This can happen in two ways:
1) 42 20-cent coins, 6 10-cent coins and 2 50-cent coins.
2) 30 10-cent coins, 10 20-cent coins and 10 50-cent coins.
Step-by-step explanation:
Given that a bag contains exactly 50 coins, and the coins are either worth 10 cents, 20 cents or 50 cents and there is at least one of each, and the total value of the coins is $ 10, to determine how many different ways can this occur, the following calculation must be performed:
48 x 0.5 + 1 x 0.2 + 1 x 0.1 = 24.30
48 x 0.1 + 1 x 0.2 + 1 x 0.5 = 5.5
48 x 0.2 + 1 x 0.1 + 1 x 0.5 = 10.3
45 x 0.2 + 4 x 0.1 + 1 x 0.5 = 9.9
44 x 0.2 + 5 x 0.1 + 1 x 0.5 = 9.8
42 x 0.2 + 6 x 0.1 + 2 x 0.5 = 10
30 x 0.1 + 10 x 0.2 + 10 x 0.5 = 10
Therefore, this can happen in two ways:
1) 42 20-cent coins, 6 10-cent coins and 2 50-cent coins.
2) 30 10-cent coins, 10 20-cent coins and 10 50-cent coins.

Given that 2 sec?0 – tan²0 = p. show that cosec²theta= p-1/p-2,p≠2
Answer:
Step-by-step explanation:
2/cos^2(theta) - sin^2(theta)/cos^(theta) = p
(2 - sin^2(theta) ) / cos^2(theta) = p
cos^2(theta) = 1 - sin^2(theta) Relationship between sines and cosines
2 - sin^2(theta)/ (1 - sin^2(theta) ) = p Everything is now in terms of sines
sin^2 (theta) = 1 / csc ^2 (theta) sin^(theta) = 1/csc(theta)
2 - 1/csc^2(theta) Make Left over csc(theta)
============== = p
1 - 1/csc^2(theta)
2 csc^2(theta) - 1
------------------------
csc^2(theta)
================ = p Cancel out denominators (csc^2(theta))
csc(theta) - 1
-------------------
csc^2(theta)
2 csc^2 (theta) - 1
=============== = p Multiply both sides by csc^2(theta) - 1
csc^2(theta) - 1
2csc^2(theta) - 1 = p*csc^2(theta) - p Collect csc^2(theta) on the left, p on the right.
csc^2(theta) (2 - p) = 1 - p
csc^2(theta) = (1 - p)/(2 - p)

Sabah has $450 to pay for college textbooks. She expects to pay about $75 per book.
Her friend told her that 4 of them can be checked out of the library for free
Complete the equation below to find the total number of books that Sabah can get for
her classes. Use b to represent the total books,
Answer:.
75(b - 4) = 450
Step-by-step explanation:
Given that :
Total amount to spend on books = 450
Total number of books = b
Cost per book = 75
Number of free books = 4
Hence, the number of books sabah will have to pay for will be :
Total Number of books - number of free books
b - 4
Cost of books purchased will be ;
Cost per book * number of books ;
75 * (b - 4)
Total cost = 450
Hence, we have ;
75(b - 4) = 450

Solve the equation by completing the square. X^2+10x+24=0
Answer:
x = -4
x = -6
Step-by-step explanation:
X^2+10x+24=0
(b/2)^2 = (10/2)^2 = 25
X^2+10x+25=-24+25
(x+5)^2 = 1
(x+5) = ± 1
x = +1 -5 = -4
x = -1 -5 = -6

Answer:
P is complementary to x
Step-by-step explanation:
Complementary means adding to 90 degrees
P+x = 90 degrees
So P is complementary to x
Answer:
( A) ∠ P
∠P is complementary angle to ∠ X .
Step-by-step explanation:
Sum of two angles of complementary angle is 90° .∠P and ∠X sum of both angles is 90°.So, they are complementary angle.P + X = 90°
P is complementary to X.
This graph shows the amount of money Leo earns from tutoring compared with the number of hours he works. Select the correct statement about the graph.
A. For each hour he works, his earnings go up by $7.
B. For each hour he works, his earnings go up by $14.
C. For every 7 hours he works, his earnings go up by $1.
D. For each dollar he earns, the number of hours he works goes up by 14.
Answer:
B. For each hour he works, his earnings go up by $14.
Step-by-step explanation:
Given
The attached graph
Required
The true statement
The attached graph is a linear graph.
From the graph, we have:
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (1,14)[/tex]
The rate (m) is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{14-0}{1-0}[/tex]
[tex]m = \frac{14}{1}[/tex]
[tex]m = 14[/tex]
This implies that the hourly rate is $14/hr
Hence (b) is true

What is the measure of Angle X? I'm not sure if its B.
Answer:
the sum of all angles in a triangle is 180°.
the two triangles got the same angles I suppose
180-85-25 = 70
70° is the answer
Answer:
X = 70
Step-by-step explanation:
Since ABC is similar to XYZ
Angle A is equal to angle X
We can find angle A since the sum of the angles of a triangle is 180
A + B+C = 180
A + 85+25 = 180
A + 110 =180
A = 180-110
A = 70
X = 70
If the Circumstance of wobble ball is 242cm what is the surface area?
Answer:
1,166 is the SA
correct me if im wrong somehow
Step-by-step explanation:
a wobble ball is a sphere
circumference=8(pi)
242=8(3.14)
so 242 divided by 25.12
this ends up with 9.633757961783439, which is the radius of the circumference
SA of a sphere= 4(pi)r²
SA=4(3.14)9.633757961783439²
SA=4(3.14)92.80929246622581
SA=1,165.684713375796
rounded to the nearest whole # = 1166
Water runs from a faucet into a bucket at a steady rate. After 4 seconds, there are 32 ounces of water in the bucket. Write an equation that shows the relationship between time and ounces of water. Use t for time in seconds and w for ounces of water.
9514 1404 393
Answer:
w = 8t
Step-by-step explanation:
If we assume that the ounces of water are proportional to the time, then the equation will look like ...
w = kt
for some constant k.
Solving for k, we find ...
k = w/t
Using the given values, we find k to be ...
k = (32 ounces)/(4 seconds) = 8 ounces/second
The units are stated in the definitions of the variables, so we can write the equation as ...
w = 8t
Which of the following is a point-slope equation of a line that passes through the points (-1, 4) and (8,-2)?
A. y-4= -3/2(x+1)
B. y-4= -2/3(x+1)
C. y-4= 2/3(x+1)
D. y-4= -2/3(x-1)
Answer:
B
Step-by-step explanation:
We want to find the point-slope equation of a line that passes through the points (-1, 4) and (8, -2).
Point-slope form is given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, let's find the slope of the line first. We can use the slope formula:
[tex]\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{-2-4}{8-(-1)}=\frac{-6}{9}=-\frac{2}{3}[/tex]
We can choose (-1, 4) as our point. So, (x₁, y₁) = (-1, 4).
Substitute:
[tex]\displaystyle y-(4)=-\frac{2}{3}(x-(-1))[/tex]
Simplify:
[tex]\displaystyle y-4=-\frac{2}{3}(x+1)[/tex]
Therefore, our answer is B.

The upper right and lower left line segments both have slopes of -2/3. Since their slopes are the same, they are parallel. The slope is found by counting grid squares between points where the lines cross grid intersections. Those crossings occur down 2 and right 3 grid squares apart, so the slope is ...

For a process, the average range for all samples was 5 and the process average was 25. If the sample size was 10, calculate UCL for the R-chart.
Answer:
8.885
Step-by-step explanation:
Given that :
Sample size, n = 10
The average range, Rbar for all samples = 5
The upper control limit, UCL for the R-chart is :
UCL L= D4Rbar
From the control chart constant table, D4 = 1.777
Hence,
UCL = 1.777 * 5
UCL = 8.885
The UCL for the R-chart is 8.885

Answer:
A. 2.1
Step-by-step explanation:
Put the numbers in the equation and do the arithmetic.
1/R = 1/(3 1/2) +1/(5 1/4)
1/R = 1/(7/2) +1/(21/4) = 2/7 +4/21 = (6 +4)/21

R = 2.1
find the unknown side lengths
Step-by-step explanation:
h = x
p = 10
b = 24
using pythagorean theorem
h² = p² + b²
h² = 10² + 24²
h² = 676
h = 26
thus , x = 26
Answer:
x = 26
Step-by-step explanation:
use the Pythagorean theorem
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {10}^{2} + {24}^{2} = {c}^{2} [/tex]
[tex] = 676 = {c}^{2} [/tex]
[tex]c = \sqrt{676} [/tex]
c = 26
What should be added to 7/12 to get -4/15 ?
Answer:
-17/20
Step-by-step explanation:
7/12 + x = -4/15
Subtract 7/12 from both sides
x = -4/15 - 7/12
Use 60 as common denominator
x = -16/60 - 35/60
x = -51/60
Reduce
x = -17/20
