Answer:
12cm
Step-by-step explanation:
this is a right angle triangle
so taking 'b' as base, 'a' as perpendicular and 'c' is hypotenuse which is equal to 13cm
and 1 angle is given which 22.6 degrees
and we need to find out 'b' which is AC
so we have
sin(x)= perpendicular/hypotenuse
cos(x)= base/hypotenuse
tan(x)=perpendicular/base
cos(22.6) = base/hypotenuse=13
cos(22.6)*13 = base
0.9232*13 = base
base = 12cm
What is the slope of the line that passes through the points (2, 9)(2,9) and (18, -3)(18,−3)? Write your answer in simplest form.
(2 ; 9) and (18 ; - 3)
slope = (-3 - 9) / (18 - 2) = -12/16 = -3/4 or - 0,75
Slope of the line that passes through the points (2, 9) and (18, -3) is -2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b
where m is the slope and b is y intercept.
The formula to calculate slope passing through two points (x1, y1) and (x2, y2) is
m= (y₂- y₁)/(x₂-x₁)
The given two points are (2, 9) and (8, -3)
Here x₁=2, y₁=9, x₂=8, and y₂=-3
Substitute the values in formula of slope.
m=-3-9/8-2
m=-12/6
m=-2
Hence slope of the line that passes through the points (2, 9) and (18, -3) is -2.

Jaime ran the first 3 1/3 miles of a 5-mile race in 1/3 hour. What was her average rate, in miles per hour, for this first part of the race? Explain how you solved the problem.
9514 1404 393
Answer:
10 mph
Step-by-step explanation:
To find miles per hour, divide miles by hours:
(3 1/3 mi)/(1/3 h) = (10/3)/(1/3) mi/h = 10 mi/h
Jaime's average rate was 10 miles per hour.

if a certain cannon is fired from a height of 8.5 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, In seconds, is found by the function h(t)=-4.9t^2+27.5t+8.5 Find the time it takes for the cannonball to strike the ground.
Answer: 2.88 seconds
Step-by-step explanation:
we need to find t in the formula, when h(t) = 0, (meaning it hits the ground).
0 = -4.9t² + 27.5t + 8.5
Using the quadratic formula:
x = (-b ± √b² - 4ac)/2a
x = (-27.5 ± √27.5² - 4(-4.9)(8.5))/2(27.5)
x = (-27.5 ± 30.38)/55
x = 2.88 OR x = -57.88
Since time cannot be negative, we will stick with the positive answer, 2.88 seconds.
Hope this helped :)

Mark McGuire hit 70 home runs in the 1998 season. Given that there are 4 bases & 90 feet between each base, how many miles did he run that season just from home runs?
Answer:
4.8 or about 5 miles
Step-by-step explanation:
In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in one mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.

Answer:
180 cm²
Step-by-step explanation:
From inspection of the diagram, the surface area is made up of the area of 4 congruent triangles and the area of one square.
Area of a square = x² (where x is the length of one side)
⇒ area of the square = 6² = 36 cm²
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 6 x 12 = 36 cm²
Total surface area = 4 x area of one triangle + area of the square
= 4 x 36 + 36
= 144 + 36
= 180 cm²
Answer:
180 I was the first so could I have brainlyest
Step-by-step explanation:
we need the area of 4 triangles and one square triangle = base x height x 1/2 square = base x height 6 x 6 = 36 + ( 6 x 12 / 2 x 4 = 144) = 180

Circle A has a circumference of 25 centimeters. Circle B's diameter is 3 times as long as circle A’s diameter. What is the circumference of circle B?
- And don’t say 10 because it’s wrong
Answer: 74.98cm
Step-by-step explanation:
Step 1: Find out radius of Circle A. [We use circumference of circle A to find its radius].
Circumference of circle A = 2πr; where r is radius.
To better viewing we change sides, we get:
2πr = Circumference of circle A
2πr = 25
r = [tex]\frac{25}{2\pi }[/tex]
r = [tex]\frac{25}{3.14}[/tex]
r ≈ 3.98
Step 2: Calculate the diameter of circle A.
diameter of circle A = 2r = 2(3.98) = 7.96
Step 3: Finding diameter of circle B.
diameter of circle B = 3(diameter of circle A) = 3(7.96) = 23.88
Step 4: Converted diameter of circle B to r.
diameter of circle B = 2r
23.88 = 2r
divided 2 from both sides, we get:
11.94 = r
Step 5: Substitute radius of circle B into the circumference formula, where C = 2πr.
C = 2πr
C = 2(3.14)(11.94)
C ≈ 74.98

Answer: $2,728.40
Step-by-step explanation:
The starting value is: $17,000

time = 14 years
Lets plug this into the interest formula:
Cost after 14 years = Principle(1 - r)^t
Cost after 14 years = 17,000(1 - 0.1225)^14
Cost after 14 years ≅$2,728.40

0.17
Step-by-step explanation:
divide one by six and you will get 0.16666 and so on, depending on the question but it will be best if you put it in two decimal place, which us 0.17
How did I get this wrong?
This value is exact
==================================================
Explanation:
Add up everyone in the "has a pet" column to get 22+78 = 100. So we have 100 people who have a pet.
Add up every value in the "male" row to get 22+66 = 88. So there are 88 males
It's tempting to say that 100+88 = 188 people either have a pet or are male, but we're double counting the 22 males who have a pet (top left corner). So we must subtract that value off to get 188-22 = 166
Another way you could look at it is to add up every value that is either in the "has pet" column or is in the "male" row, giving us: 22+78+66 = 166
So there are 166 people who either have a pet, are male, or both.
This is out of 22+66+78+34 = 200 people total
Divide the two values to get 166/200 = 0.83 = 83%

True or False. A function is increasing if its outputs get larger as the inputs
get larger.*
Answer:
True
Step-by-step explanation:
A function is increasing if its outputs get larger as the inputs is a "true statement" or the first option. If the inputs are getting larger for every input and the outputs are getting larger for every output, if you plot the data on a scatter plot or a coordinate plane of sorts you would see it take shape of a line that is moving from the left to the top right which means the function is indeed increasing when the outputs/inputs get larger.
Hope this helps.
