In right ABC angle c is the right angle, AC = 7, and BC = 24. Find the value of the sine of the largest acute angle of the triangle.
Answer:
Step-by-step explanation:
Remark
AC and BC are the legs of a triangle. You are told that the right angle is at C. Both these sides have one endpoint C. That means that they are the shorter of the three lines. The first thing we must do is find the Hypotenuse. You need the Hypotenuse to get the sin of one or both of the acute angles.
Hypotenuse
a^2 + b^2 = c^2
a = 7
b = 24
c = ?
c^2 = 7^2 + 24^2
c^2 = 49 + 576
c^2 = 625
sqrt(c^2) = sqrt(625)
c = 25
Find the Largest Angle
The largest angle is going to be opposite the longest leg (not the Hypotenuse although you use the hypotenuse).
Sin(A) = 24/ 25
Sin(A) = 0.96
A = Sin-1(0.96)
A = 73.74

Answer:
Step-by-step explanation:
r=4, w=3, b=2, g=1, t=(4+3+2+1)=10
9) P(r or g)=4/10+1/10=5/10= 1/2
10) P(r or b)=4/10+2/10=6/10= 3/5
11) P(!b)=P(r or w or g)=4/10+3/10+1/10=8/10= 4/5
12) There are six numbers and only one six, P(6)= 1/6
13) The only even numbers less than 5 are 2 and four so
P(e<5)=2/6= 1/3
14) The primes on a die are 2,3,5 so three primes out of six numbers
P(!)=3/6= 1/2
15) 2,3,4,6 are multiples of 2 and three
P(2n or 3n)=4/6= 2/3
16) We want a one half probability so
P(W)=(3+x)/(3+4+2+x)=1/2
(3+x)/(9+x)=1/2
2(3+x)=9+x
6+2x=9+x
x=3
So 3 white marbles have to be added.
17) (3+x)/(9+x)=2/3
3(3+x)=2(9+x)
9+3x=18+2x
x=9
So nine whites need to be added.

tamika has $55 in her savings account. She plans on depostiting $5 per week into her account. Write and solve an inqequality to find out how many weeks she must save to have more than $100 in her account. Then interpet the solution
Answer:
x>9
Step-by-step explanation:
Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.
The question also asks to solve the inequality:
55+5x>1005x>100-55 (Subtract 55 from each side)5x>45x>9 (Divide each side by 5)This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.

Answer:
First option: 336
Step-by-step explanation:
To find the answer, separately solve for each of the shapes.
1. The base is the square so length times width is the formula:
12 x 12 = 144
144 is the area of the square
Next, find the 4 triangles which are congruent(the same).
Triangle area formula: Base x Height divided by 2.
So, the area of 1 triangle is 12 x 8 =96
96/2 = 48
Area =48
Because there are 4 triangles, do 48 x 4=192.
Finally, add the area together and you should get 192+144 =336 ft^2
Surface area = 336 ft^2
Give step by step instructions and the final answer on how to find the volume of a right square pyramid who has a slant height of 5 inches and the length of the base is 4 inches.
To earn full points you must :
- Show each step of your work
- Keep it organized and easy to read
- Give a brief explanation of why you perform each step
- give the correct final answer
Answer:
Below.
Step-by-step explanation:
First find the perpendicular height of the pyramid.
The median of one of the faces, the height and and half the length of the square base make a right triangle with base 2 and hypotenuse 5, so using the Pythagoras theorem:
5^2 = 2^2 + h^2
h^2 = 5^2 - 2^2 = 21
h = √21 inches.
The volume of the pyramid V = 1/3 * h * area of the base, so
V = 1/3 * 4^2 * √21
= 24.44 in^3 to nearest hundredth.
The volume of a right square pyramid will be (16√21) / 3 cubic units.
What is the volume of the pyramid?Let h be the height of the pyramid, l be the slant height and A be the base area of the pyramid.
Then the volume of the pyramid will be
Volume = (1/3) × A × h
The slant height is given as.
l² = (half of side)² + h²
A right square pyramid has a slant height of 5 inches and the length of the base is 4 inches.
Then the height of the pyramid will be
5² = (4/2)² + h²
h² = 25 - 4
h = √21 inches
Then the volume of a right square pyramid will be
Volume = (1/3) × 4 × 4 × √21
Volume = (16√21) / 3
Thus, the volume of a right square pyramid will be (16√21) / 3 cubic units.
More about the volume of the pyramid link is given below.

Answer:
See below, please!
Step-by-step explanation:
We know that 6z-31+something is going to be equal to 180 degrees, because it is supplementary. But what is that something? We see 67 degrees. Do you think this is a corresponding angle to the something that we need to find? Yes, it is! So we know that 6z-31+67 is equal to 180. So, z is 24. Now, since we know the value of the something (67 degrees because of corresponding angles) we can find yet another pair of supplementary angles. 67+x=180! Kind of neat, huh? So, x is equal to 113.
Hope this helped!

Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = 6x
Explaination:
slope intercept form is just y=mx+b, and since the slope is 6, you plug 6 into m, and then the y-intercept is 0, so you can drop it out of the equation

On a certain hot summer's day, 540 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $822.75. How many children and how many adults swam at the public pool that day?
Answer:
There were 343 children and 197 adults.
Step-by-step explanation:
In order to solve this problem, you can use an equation after identifying the important information, like that there were 540 people, the cost for a child is $1.25, the cost for an adult is $2.00, and admission fees totaled $822.75:
where c = number of children, and a = number of adults,
c + a = 540
1.25c + 2a = 822.75
Now, you need to solve this system of equations by isolating one of the variables. I'll isolate c by multiplying the first equation by 2 since it's easier:
2c + 2a = 1080
- 1.25c + 2a = 822.75
= .75c = 257.25
Now, you can multiply both sides by 4/3 to find c:
c = 257.25 × 4 ÷ 3
c = 343
So there were 343 children. Now you can find the number of adults by substituting 343 for c in the first equation:
where c + a = 540 and c = 343,
343 + a = 540
a = 197
So, there were 197 adults.

Stephen is testing the difference in means between time it takes to travel school in a bus and time it takes to travel to school in a car. Stephen hypothesizes that it takes more time to travel in a bus. He calculates a p-value of 2%. He concludes at a 1% significance level that the true mean is greater for a bus than a car.
Where did Stephen go wrong in his conclusion? Explain in detail.
Answer:
Kindly check explanation
Step-by-step explanation:
To test for Difference in mean times
Null hypothesis, H0 will be, there is no difference in mean times ; m1 = m2
Alternative hypothesis, there is difference in mean times ; m1 ≠ m2
Decision region :
When p value < α ; reject the Null
Here. ;
Pvalue = 2% = 0.02
α = 1% = 0.01
Pvalue > α
0.02 > 0.01
Since, Pvalue > α ; we do not reject the Null ;
Hence, conclusion should be, there is no difference in mean times of bus and car
