Answer:
[tex]-\sqrt2[/tex]
Step-by-step explanation:
csc 225 degrees is the multiplicative inverse of sin 225 degrees. sin 225 degrees. We can use a unit circle with radius of 1 to find out sin 225 degrees. a 225 degree rotation counter clockwise is equivalent to a 180 degree turn followed by a 45 degree turn. Therefore, the final value is going to be in the third quadrant, a 45 degree turn in. This means that sin(225 degrees) = [tex]-\sqrt2/2[/tex] The multiplicative inverse of that is [tex]-\sqrt2[/tex]

Patricia jumped 5 times in 12 minutes. At that rate, how many times
would she jump in 8 hours?
Tahol nntinnal
Answer:
200
Step-by-step explanation:
Change 8 hours to minutes so the units are the same. 8(60) = 480. Using a proportion the equation is 5/12 = j/480. [jumps/minutes] To solve the equation, cross multiply: 12j = 5(480) ; 12j = 2400; j = 2400/12; j = 200.

The total amount of weight on an elevator cannot exceed 1,800 pounds. a delivery person is on the elevator delivering packages. together, the delivery person and the packages weigh 520 pounds. if the average weight of a person is 160 pounds, set up and solve an inequality to determine how many additional people, p, the elevator can hold.
Answer:
p ≤ 8
Step-by-step explanation:
Given the following :
Maximum weight elevator can hold ≤ 1800
Weight of delivery person and packages = 520 pounds
Average weight of a person = 160 pounds
Inequality to show how many additional people elevator can hold?
(weight of delivery person and packages + average weight of persons * number of persons) ≤ 1800
Let p = number of persons
(520 + 160p) ≤ 1800
160p ≤ 1800 - 520
160p ≤ 1280
p ≤ 1280 / 160
p ≤ 8
Find the value of the angle θ rounded to 1 DP.
The diagram is not drawn accurately.
The measure of the indicated angle θ is approximately 39.9°.
Use the concept of a triangle defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
After labeling the figure
In triangle ABC
Sin θ = AC/AB
Sin 26° = AC/19
AC ≈ 0.44 x 19
AC ≈ 8.36
Now in Triangle ADC,
tan θ = (opposite side of θ)/(Adjacent side)
tan θ ≈ 7/8.36
tan θ ≈ 0.837
Take the inverse of tan on both sides, we get,
θ ≈ 39.9°
Hence,
The value of angle θ is approximately 39.9°.

A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
Tank A holds 40 L and 5 fish. Tank B holds 100 L and 12 fish. Tank holds 180 L and 23 fish,
Order the tanks by volume per fish from least to greatest
For each tank just divide the number of L by the number of fish to get the volume or fish.
For tank A it is 40/5=8, for tank B it is 100/12=8.3, and for tank C it is 180/23=7.8.
If you number them least to greatest, it is (tank C, tank A, tank B)

From your house, Joe's mechanic shop is 25 miles away. At what rate must you travel to
go 25 miles to make your appointment in 0.27 hours?
Answer:
rate = 92.6 miles/hours
Step-by-step explanation:
Here rate means speed
formula for speed = distance/time
since distance here is 25 miles
and time taken is 0.27 hours
thus,
speed = distance to be traveled/time in which this distance is covered
speed = 25 miles/ 0.27 hours = 92.6 miles/hours
thus, rate should be 92.6 miles/hours to make the appointment in time.

On a windmill, the tip of one blade moves in a circular motion. The maximum height is 18 feet and the minimum height is 4 feet. The height of the tip of the blade (in feet) can be modeled by the function h(x)=−14sinx+18 h(x)=−14sinx+18 where x is time in seconds. Use the inverse function to determine how many seconds it will take to make a full rotation for one blade.
A 0.3 second
B 0.6 second
C 1.6 seconds
D 3.2 seconds
Answer:
The correction is D
Step-by-step explanation:
From the question we are told that
The maximum height is [tex]h_m = 18 ft[/tex]
The minimum height is [tex]h_i = 4 ft[/tex]
The function that models the height of the blade is [tex]h(x) =- 14 sin(x) + 18[/tex] here x is time in seconds
Now at maximum height
[tex]18 = - 14 sin(x) + 18[/tex]
=> [tex]-14 sin(x) =0[/tex]
=> [tex]sin(x) =0[/tex]
=> [tex]x =sin^{-1}[0][/tex]
=> [tex]x =0 \ s[/tex]
Now at minimum height
[tex]4 = -14 sin(x) + 18[/tex]
=> [tex]-14 = -14 sin(x)[/tex]
=> [tex]sin (x) = 1[/tex]
=> [tex](x) = sin^{-1}[1][/tex]
=> [tex]x = 1.6 \ s[/tex]
Now this values is the time taken to move from the higher position of the blade to the lower position of the blade
Now it will take this same amount of time to complete the circle
So the total time take is
[tex]x_t = 2 * |x|[/tex]
=> [tex]x_t = 2 * 1.6[/tex]
=> [tex]x_t = 3.2 \ s[/tex]

An airplane flies from Minneapolis to Chicago in 58 minutes.
If it is 572,000 meters from Minneapolis to Chicago, what is the plane's average speed?
20 points and Brainliest.
Answer:
9862.069 meters per minute
or
591724.138 meters per hour
Step-by-step explanation:
572000 meters ÷ 58 minutes = 9862.069 meters per minute
If you need this in meters per hour, multiply by 60 as there are 60 minutes in 1 hour.
60 * 9862.069 = 591724.138 meters per hour
If you need to convert to miles per hour:
1 meter = 0.0006213712 miles
591724.138 * 0.0006213712 = 367.68 miles per hour

(Terms and Equations in Factual Problems) The Smith family consists of four people. Anna is three years older than Matthias. Miss Smith is four times as old as Anna. Mr Smith is five years older than his wife. Together they are 72 years. How old are the family members?
Given:
Anna is three years older than Matthias.
Miss Smith is four times as old as Anna.
Mr Smith is five years older than his wife.
Together they are 72 years.
To find:
The age of each family member.
Solution:
Let age of Matthias be x years.
Anna is three years older than Matthias.
Anna's age = x+3
Miss Smith is four times as old as Anna.
Miss Smith's age = 4(x+3)
Mr Smith is five years older than his wife Mrs Smith.
Mr Smith's age = 4(x+3)+5
Together they are 72 years.
[tex]x+(x+3)+4(x+3)+[4(x+3)+5]=72[/tex]
[tex]x+x+3+4x+12+4x+12+5=72[/tex]
[tex]10x+32=72[/tex]
Subtract 32 from both sides.
[tex]10x=72-32[/tex]
[tex]10x=40[/tex]
Divide both sides by 10.
[tex]x=4[/tex]
Now,
Matthias's age = 4 years
Anna's age = 4+3
= 7 years
Miss Smith's age = 4(4+3)
= 4(7)
= 28 years
Mr. Smith's age = 4(4+3)+ 5
= 28+5
= 33 years
Therefore, the ages of Matthias, Anna, Miss Smith and Mr Smith are 4, 7, 28 and 33 respectively.

Answer:
I would say about 13 minutes.
Step-by-step explanation:
9 4/5 KPH is about 6.1224489795918 Kilometers per minute
Multiply by 2 1/5 KPM
6.1224489795918 x 2 1/5 = 13.4693877551 Minutes
Answer: 13.469 or about 13.5 minutes
Step-by-step explanation:
Estimating part:
The first number can be rounded to 10, and second number to 2
You can set up a proportional equation
[tex]\frac{10 kilometers}{60 minutes} = \frac{2 kilometers}{x}[/tex]
then cross multiply to get 10x=120, then divide to get x = 12 minutes
Exact answer:
I like making fractions into decimals to make it easier to see
The first number as a decimal is 9.8, and the second is 2.2
Set up another proportional equation
[tex]\frac{9.8 kilometers}{60 minutes} = \frac{2.2 kilometers}{x}[/tex]
cross multiply to get 9.8x = 132
divide by 9.8 on both sides to get x = 13.5 minutes
Classify the relationship between angle 4 and angle 5.
Angle 4 and angle 5 are interior angles on the same side of transversal , which means the sum of angle 4 and angle 5 will be equal to 180° .
please walk me through this
Answer:
X is 160. because you can add all the value of x. But first substrate 540 with 100 which is 440. then 1/2x + 1/2x+ (x-15) + (x-25) which is further simplified as x + 2x - 40. then it's further simplified as 3x - 40 = 440. then add 40 with 440 which is 480 then divide it by 3 which is 160. therefore X= 160.
