Steven and his family ordered a meal the cost 136.50. Steven paid 14% sales tax and left a 20% tip on 136.50. What was the total cost
Answers
Answer:
The total cost was $182.91.
Step-by-step explanation:
Tax formula:
tax=tax percentage×amount
Tip formula:
tip=tip percentage×amount
solve
First find the tax. Write 14% as the decimal 0.14 before using it in the equation.
tax
= tax percentage×amount
= 0.14×136.50
= 19.11
The tax was $19.11.
Now find the tip. Write 20% as the decimal 0.20 before using it in the equation.
tip
= tip percentage×amount
= 0.20×136.50
= 27.3
The tip was $27.30.
Finally, find the total cost.
total cost
= cost + tax+tip
= 136.50+19.11+27.30
= 182.91
Answer:
182.91

The Dakotas rented a minivan for their family vacation. When they returned
from vacation, the total bill for the van was $575. The standard weekly rate
from the rental company is $355 plus $55 for each additional day of usage.
How many additional days did the Dakotas have the minivan?
Answers
Answer:
4 additional days.
Step-by-step explanation:
So the total charge is $575.
It costs $355 for 1 week of use of the van.
1 week is 7 days.
It costs $55 for each extra day of use of the van.
575=55d+355
d is for the unknown extra amount of days.
subtract 355 from both sides
220=55d
divide by 55 on both sides
4=d
So, the Dakotas used the van for 4 additional days. So in total the used the van for 4+7 days.
4+7=11 total days.
But the answer to the question is 4 days, because it specifically ask for additional days.

It might help to draw a triangle to represent what's going on. See the diagram below.
Let's call the triangle ABC. We'll place point A at the 90 degree angle, so it's at the base of the tower. Place point B where the knight is located. Point C is the location of the window in the tower.
The knight is 15 feet away from the base, meaning AB = 15. With respect to the reference angle (B = 60), side AB = 15 is the adjacent side. The length of the ladder BC is the unknown hypotenuse. We'll call this x for now.
We'll use the cosine rule to connect the adjacent and hypotenuse.
cos(angle) = adjacent/hypotenuse
cos(B) = AB/BC
cos(60) = 15/x
x*cos(60) = 15
x = 15/cos(60)
x = 30
Your calculator needs to be in degree mode.
Because x = 30, we conclude that the ladder needs to be BC = 30 feet long.
Side note: For any special 30-60-90 right triangle, the hypotenuse is always twice as long compared to the shorter leg.
The ratio of blue cars to red cars in a garage is 9:7. If there are 49 red cars in the garage then how many blue cars must be in the
garage?
Answers
Answer:
Blue cars, B = 63 cars
Step-by-step explanation:
Let the blue cars be B.
Let the red cars be R.
Given the following data;
Ratio of B:R = 9:7 = 9 + 7 = 16
Red cars, R = 49
To find the number of blue cars;
First of all, we would determine the total number of cars using the expression;
R = 7/16 * x = 49
7x = 49 * 16
7x = 784
x = 112 cars
Now, we can find the number of blue cars;
B = 9/16 * 112
B = 1008/16
Blue cars, B = 63 cars

Answers
Answer:
Yes, Billy will have enough money to buy two denim shirts.
Step-by-step explanation:
£9.60 × (1/3)
= £3.20
On the special offer day, a denim shirt will cost £3.20.
£3.20×2 = £6.40
Two shirts will cost £6.40
Billy has £13, which will be enough for him to buy two shirts and will have a remaining balance of £6.60

You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly more than 40%. With H1 : p > 40% you obtain a test statistic of z = 1.574. Find the p-value accurate to 4 decimal places.
Answers
Answer:
The p-value is 0.0577.
Step-by-step explanation:
The alternate hypothesis is:
[tex]H_1: p > 40\%[/tex]
P-value of the test:
The p-value of the test is the probability of finding a sample proportion above the one found, which is 1 subtracted by the p-value of z.
We have that z = 1.574.
Looking at the z-table, z = 1.574 has a p-value of 0.9423
1 - 0.9423 = 0.0577
The p-value is 0.0577.
What is the volume of the solid if a 6 inch (diameter hole is drilled all the way
Answers
Answer:
1,467.6 cm³
Step-by-step explanation:
Volume of the solid = volume of the rectangular prism - volume of the cylinder
= L*W*H - πr²h
L = 12
W = 10
H = 16
r = ½(6) = 3
h = 16
Plug in the values
Volume of the solid = 12*10*16 - π*3²*16
= 1,920 - 452.40
= 1,467.6 cm³

Given expression;
n(n - x) = 25
From the given expression, x = 0
Substitute the value of x into the given equation and solve for n;
n(n - 0) = 25
this equation reduces to;
n(n) = 25
simplifying further to obtain the value of n;
n² = 25
n = √25
n = 5
Therefore, the correct option is B.

Add all them up then make them equal 180 degrees
9x-9 = 180
Solve
9x=180 +9
9x= 189
9x/9= 189/9
x=21
Then plug in x to find each Angle.
N (x) Degrees
