can someone help me please?
Answer:
see explanation
Step-by-step explanation:
(a)
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180° for B
∠ B = 180° - (90 + 63)° = 180° - 153° = 27°
(b)
Using the sine ratio in the right triangle
sin63° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )
x × sin63° = 15 ( divide both sides by sin63° )
x = [tex]\frac{15}{sin63}[/tex] ≈ 16.8 ( to 1 dec. place )
(c)
Using the tangent ratio in the right triangle
tan63° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{y}[/tex] ( multiply both sides by y )
y × tan63° = 15 ( divide both sides by tan63° )
y = [tex]\frac{15}{tan63}[/tex] ≈ 7.6 ( to 1 dec. place )

Answer:
3 1/8 divided by 3/4 = 4 1/6. basically 5 containers.
Peter has a coupon for 15% off the price of any item in a sporting goods store. He wants to buy a pair of shoes that are priced at $36.99. About how much will the shoes cost after the discount.
Answer:
$31.43
Step-by-step explanation:
If you take 15% of 36.99 you get around 5.56. So all you have to do is subtract that from the original amount.
Solve for p.
2p + 1=1
5p + 6=7
Answer:
-1/9
Step-by-step explanation:
We need to solve out and find out the value of p . The given equations is.
=> 2p + 1/ 5p + 6 = 1/7
=> 7 ( 2p + 1) = 5p + 6
=> 14p + 7 = 5p + 6
=> 14p - 5p = 6-7
=> 9p = -1
=> p = -1/9
• Hence the value of p is -1/9

The graphs below show the number of faulty products, y, produced by a company for the first eight months since production started. Both graphs show the same information.
Answer:
Graph A ,appears to decrease less
Step-by-step explanation:
In the word problem it asked us which graph seem to have "Slight Decrease"means if obeserve the graph it shows graph A.
Alex should use Graph A for the presentation as it shows the number of faulty products as a decrease on the graph
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let graph A shows the product quality with number of faulty products over the period of months
And , let graph B shows the product quality with number of faulty products over the period of months
Now , the line is decreasing in a steady manner in graph A as the number of faulty products is decreasing at a nominal rate
Hence , graph A is best for presentation

In ΔSTU, t = 3.4 cm, u = 6.9 cm and ∠S=21°. Find the area of ΔSTU, to the nearest 10th of a square centimeter.
Answer:
4.2
Step-by-step explanation
Delta
The area of the triangle STU to the nearest of a square centimeter is 4.2 cm².
Area of a trianglearea of the triangle = 1 / 2 tu sin S
where
height = u sin STherefore,
t = 3.4 cm
u = 6.9 cm
∠S = 21°
Hence,
area of the triangle = 1 / 2 × 3.4 × 6.9 sin 21°
area of the triangle = 23.46 sin 21 / 2
area of the triangle = 23.46 × 0.35836794954 / 2
area of the triangle = 8.40731209633 / 2
area of the triangle = 4.20365604817
area of the triangle = 4.2 cm²

Judy and 2 friends won $145.00 at a fundraising raffle! They agreed to share the winnings equally. They received one $100 bill, four $10 bills, and five $1 bills
Answer:
There are 3 friends (Judy + 2 friends) who won $145.00
They want to share the winnings equally, but they got:
one $100 bill
four $10 bills
five $1 bills.
Assuming that they can share only those bills, the only way to share the winnings equally is:
Each friend gets one $10 bill
Each friend gets one $1 bill
Then each one gets $11.
And there is a surplus of:
one $100 bill (that can't be divided)
one $10 bill (that can't be divided)
two $1 bill (that can't be divided)
Then:
There is a common pool of $100 + $10 + 2*$1 = $112
And each one of the 3 friends gets $10 + $1 = $11
In the case where they can change the bills, each friend will get:
$145/3 = $48.33

All chicken wings are $0.25. Your waiter also announces
that for your stay there will be an additional 20%
discount on wings. Your table of friends stays there for
2 hours and eats a total of 78 wings. How much do you
expect the bill to be for your wings?
na
Answer:
If the 20% discount is by the hour then the answer would be $11.70 I think.
0.25x78= 19.50
19.50x0.20(20%)= 3.90
19.50-3.90-3.90= 11.70

Identify a function rule for the following ordered pairs (0, -1), (2, 3), (3, 8), (4, 15)
A) y=x^2
B) y=x-1
C) y=x²-1
D) y=2x-1
Answer:
C
Step-by-step explanation:
Looking at the first point we know that it can't be A
Then we can easily see that the rate of change is not level (which means it isn't linear)
this leaves option C
Another way to solve this is just by plugging in points
for example for C
(4,15)
15=4^2-1
15=15

A train travels 120 mi in 1 hour and 20 minutes. How many miles will the train go in 6 hours traveling at the same rate?
Answer: 541.32 miles
Step-by-step explanation:
First find the speed of the train in miles per hour.
1 hour 20 minutes needs to be converted to decimal:
= 1 20/60
= 80/60
= 1.33 hours
Speed is:
= Distance / Time
= 120/ 1.33
= 90.22 miles an hour
If the train is traveling 6 hours at the above speed, it will travel:
= Speed * time
= 90.22 * 6
= 541.32 miles
