Step-by-step explanation:
44 ft in 3 seconds
in 1 hour there are 60 minutes with 60 seconds each.
so, 1 hour = 60×60 = 3600 seconds.
in 3600 seconds there are
3600 / 3 = 1200 "packages" of 3 seconds.
so, Jerry would run
1200 × 44 = 52800 ft in 1 hour.
there are 5280 ft in 1 mile.
that means Jerry would run
52800 / 5280 = 10 miles in 1 hour.

Find the mean of the data. 20, 28, 30, 38, 39, 40, 43
Answer:
mean = 34
Step-by-step explanation:
the mean is calculated as
mean = [tex]\frac{sum}{count}[/tex] = [tex]\frac{20+28+30+38+39+40+43}{7}[/tex] = [tex]\frac{238}{7}[/tex] = 34
Answer: 34
Step-by-step explanation:
Mean is the same as average, and to find average you add all the numbers up and divide by the amount of numbers present. So, if you add all of them up, you get 238. Then, you'll divide by 7, since there are 7 numbers. And that will get you 34.

Answer:
a) angle QRP is 92 degrees, side QR is 23 cm, angle RPQ is 47 degrees
b) angle EFD is 65 degrees, side FD is 22cm, side ED is 20cm
Step-by-step explanation:
a) in the first example, you know that u are given QR, PR, and angle PRQ, and u are asked to find triangle PQR,or the rest of the lengths.
step 1-u draw an example of the triangle, i will provide one for each at the bottom of this answer
step 2-lets find the sides first with the pythagorean theorem, which will mean 25²+x²=34². Pythagorean theorem is a²+b²=c²
step 3-after solving for x, x will be 23.04, which means the third side is 23 cm (after rounding).
step 4-now that we have all the sides, we can solve for the rest of the angles, by trigonometric ratios, we are gonna use sine for angle RPQ, sine is sin(the angle u want to find)=opposite side/hypotenuse.
step 5- so sin(RPQ)=25/34, and solve for RPQ on a calculator (i used math) and angle RPQ will equal 47.3 degrees.
step 6- just subtract the sum of both angles from 180 an the last angle will be 92 degrees.
b) u are given the measure of angles FED and EDF and the side length FE, we will solve for the last angle first then we will go for the side engths
step 1- we subtract the sum of the two angles we have from 180 and we will get the measure of angle EFD to be 65 degrees, now we have the angles and we want to find he sides.
step 2-we use sine of angle 31 degrees to find the hypotenuse, but it is opposite of sine since we want to find the side, not the angle, so we will use sin(31)=11.3/x, the sine equation is written like sin(the angle u have)=opposite/hypotenuse.
step 3- after solving for arc sine in a calculator, u will find side FD to be 22cm, and now to find the last side.
step 4-i will use the sine of angle 65 degrees to solve for side ED, it will be sin(65)=x/22, which will make side ED equal 20 cm in length.

You pick a card at random, put it back, and then pick another card at random
5 6 7
What is the probability of picking a 7 and then picking a 5?
Write your answer as a fraction or whole number.
Answer:
The probability is 1/9
Step-by-step explanation:
1/3 x 1/3 = 1/9
Reason:
The probability of selecting "7" is 1/3 because there's one card labeled "7" out of three cards total.
The same applies to selecting a "5" as well. When the first card is put back, effectively nothing has changed.
The probability of getting a "7", then getting a "5" is (1/3)*(1/3) = 1/9

a helicopter took 39 minutes to fly 91 miles, traveling in a headwind. the same helicopter took one hour and 15 minutes to fly 195 miles flying in the opposite direction. if the wind speed and direction was the same for both flights, find the speed of the helicopter in still air and the wind speed. gina wilson algebra brainly
Using the relation between velocity, distance and time, it is found that the velocity of the helicopter is of 225 mph and of the wind is of 69 mph.
What is the relation between velocity, distance and time?Velocity is given by distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
A helicopter took 39 minutes to fly 191 miles, traveling in a headwind. Due to the headwind, the relative velocity is the sum of the velocities, hence:
[tex]v_h + v_w = \frac{191}{\frac{39}{60}}[/tex]
[tex]v_h + v_w = 294[/tex]
[tex]v_w = 294 - v_h[/tex]
The same helicopter took one hour and 15 minutes to fly 195 miles flying in the opposite direction, hence:
[tex]v_h - v_w = \frac{195}{\frac{75}{60}}[/tex]
[tex]v_h - v_w = 156[/tex]
Since [tex]v_w = 294 - v_h[/tex]:
[tex]v_h - 294 + v_h = 156[/tex]
[tex]2v_h = 450[/tex]
[tex]v_h = 225[/tex]

The perimeter of a square is 24 feet. What is the area in square feet
Answer:
Step-by-step explanation:
Remark
You need 2 formulas to solve this. Use perimeter first and then area.
Formulas
P = 4s
Area = s^2
Givens
Perimeter = 24 feet
Solution
P = 4*s Substitute the value for P
24 feet = 4s Divide both sides by 4
24/4 = 4s/4
6 = s
Now use the area formula
Area = s^2 Substitute 6 for s
Area = 6^2
Area = 36 feet^2
Answer
Area = 36 ft^2
The perimeter of a square is 24 feet. What is the area in square feet.

Orlando is mixing nuts and cereal squares to make a party mix. Nuts sell for $7 a pound and cereal squares sell for $4 a pound. If Orlando wants to make 30 pounds of party mix at a cost of $6.50 a pound, how many pounds of nuts and how many pounds of cereal squares should he use?
Answer:
0.5lb cereal squares, 0.75 lb nuts
Step-by-step explanation:
1lb nuts = $7
multiply each side by 1/2 (whatever you do to one side, you do to the other),
0.5lb nuts = $3.5
1lb cereal squares = $4
multiply each side by 3/4 (whatever you do to one side, you do to the other),
0.75lb cereal squares = $3
0.5lb nuts + 0.75lb cereal squares = 3.5 + 3 = $6.5
Find the value of x.
Answer:

Following the vertical angles, we can assume that the equation that has x and 87 are equal to each other. From then, you set them equal to each other and solve for x.
87=4x+3
84=4x subtract 3 from both sides
21=x divide by 4 to get the x alone on both sides
