Answer:
37.9 degrees
Step-by-step explanation:
Using the law of sines, [tex]\frac{\sin(m\angle C)}{21}=\frac{\sin(47^\text{o})}{25}[/tex]. It follows that [tex]\sin (m\angle C) = \frac{21\sin(47^\text{o})}{25} \approx 0.6143371[/tex]. Therefore, [tex]m\angle C = \sin^{-1}(0.6143371)=37.9^\text{o}[/tex].

-3x + 10 > 22
A. X >-4
B. X <-4
C. X>4
D. X <-4
Nee
Answer:
X<-4
Step-by-step explanation:
-3x+10>22
subtract 10 to both sides
-3x>12
divide by -3 on both sides
when you divide by a negative number you flip the sign so the answer will be x<-4

Raj builds a side table in the shape of a cube. Each edge of the cube measures 21 inches. Raj wants to cover the top and four sides of the table with ceramic tiles. Each tile has an edge length of 3 inches. How many tiles will he need?
Pls answer fast
Answer: 2000/25 = 80 tiles
Step-by-step explanation:
Date: s=20
equation of surface area of a cube prism: surface area = 6s*2
the surface area to be covered with tiles is requires, the base is not included, so the equation reduces: surface area = 5s*2
subtitute values: surface area = 5(20)*2
= 5(400)
surface area = 2000
area of 2 tile is 5*2 = 25 square inches
2000/25 = 80 tiles

The Coopers own two vehicles, a mini-van and sedan. The following functions represent the resale value of both cars, in thousands of dollars,
after x years.
Mini-Van: f(1) = 32(0.8)*
Sedan: g(t) = 25(0.8)
Write function t that represents the total resale value, in thousands of dollars, of the two vehicles.
Answer:
[tex]h(x) = 57(0.8)^x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 32(0.8)^x[/tex]
[tex]g(x) = 25(0.8)^x[/tex]
Required
A function that represents the total resale value of the two vehicles
To do this, we simply add up the functions
[tex]h(x) = f(x) + g(x)[/tex]
[tex]h(x) = 32(0.8)^x + 25(0.8)^x[/tex]
Factorize
[tex]h(x) = (32 + 25)(0.8)^x[/tex]
[tex]h(x) = 57(0.8)^x[/tex]

A firefighter is on the fifth floor of an office building. She needs to throw a rope into the window on the seventh floor, 40 feet above her. If she throws the rope upward with an initial velocity of 36 ft/s, will the rope get to the window.
Answer:
no, it wont
Step-by-step explanation:
2g.h = v²
2(33)(40) = v²
2640=v²
v=√2640 = 51.38 ft/s
36 < 51.38

Classify the polynomial by the number of terms.
mx+b
•Trinomial
•Monomial
•Polynomial
•Binomial
Classification:
Monomial: One term
Mono = One
Polynomial: Multiple terms e.g. (2,3,4 and so on)
Poly: Many
Binomial: Two terms
Bi = Two
Trinomial: Three terms
Tri = Three
The expression of "mx + b" would be classified as a monomial due to it having only one exponent.

Consider the following data that represents gas mileages per gallon (mpg) of randomly selected cars of a particular brand.
28 32 23 28 24 36 31 34 25 28 29 23 25
A researcher wants to test whether the average gas mileage of this type of car is different from 30 mpg. Compute the p-value.
Answer:
The p-value is 0.1228.
Step-by-step explanation:
Before testing the hypothesis, we need to find the sample mean and the standard deviation.
Sample of 13:
The sample mean is the sum of all values divided by 13. Using a calculator, it is: X = 28.15.
The sample standard deviation is the square root of the division of the sum of the differences squared between each value and the mean, by the number of values. Using a calculator, we get s = 4.0162.
A researcher wants to test whether the average gas mileage of this type of car is different from 30 mpg.
At the null hypothesis, we test if the average gas mileage is of 30 mpg, that is:
[tex]H_0: \mu = 30[/tex]
At the alternate hypothesis, we test if the average is different from 30, that is:
[tex]H_1: \mu \neq 30[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
30 is tested at the null hypothesis:
This means that [tex]\mu = 30[/tex]
From the sample:
[tex]X = 28.15, s = 4.0162[/tex].
Value of the test-statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{28.15 - 30}{\frac{4.0162}{\sqrt{13}}}[/tex]
[tex]t = -1.66[/tex]
P-value of the test:
The p-value of the test is the probability that the sample mean differs from 30 by at least |28.15 - 30| = 1.75, which is a two-tailed test with t = -1.66 and 13 - 1 = 12 df.
Using a t-distribution calculator, this p-value is 0.1228.
What is the diameter of a hemisphere with a volume of 5990in^3 to the nearest tenth of an inch?
Answer:28.4
Step-by-step explanation:
Delta Math
The diameter of the asked hemisphere is 28.38 in.
What is hemisphere?The half of a sphere is called a hemisphere.
Given that, a hemisphere with a volume of 5990 in³
Volume of a hemisphere = 2/3πr³
2/3πr³ = 5990
r³ = 5990x7x3/22x2
r³ = 125790/44
r³ = 2858.8636
r = 28.38
Hence, The diameter of the asked hemisphere is 28.38 in.

X= root (y-1/y+1) ( make “y” as subject. ) number 19
Answer:
y = (x² + 1) / (1 – x²)
Step-by-step explanation:
x = √[(y – 1)/(y + 1)]
We can make y the subject of the expression as shown below:
x = √[(y – 1)/(y + 1)]
Take the square of both side
x² = (y – 1) /(y + 1)
Cross multiply
x²(y + 1) = (y – 1)
Clear bracket
x²y + x² = y – 1
Rearrange
x² + 1 = y – x²y
Factorise
x² + 1 = y(1 – x²)
Divide both side by (1 – x²)
y = (x² + 1) / (1 – x²)
