HELP MEEEE

Answer: 131 miles; 21 x 3 = 63 + 17 x 4 = 68. 63 + 68 = 131 miles

Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.

What is the speed?

The magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Here given that,

A cyclist rode at a constant speed of [tex]21[/tex]mph for [tex]3[/tex] hours. Then she decreased her rate of speed to [tex]17[/tex] mph for [tex]4[/tex] hours.

[tex]21[/tex] x [tex]3[/tex]  [tex]=63 + 17 (4)[/tex]

[tex]= 131[/tex] miles

Hence, the cyclist ride in [tex]7[/tex] hour is [tex]131[/tex]miles.

Answer:

1) = 180 degree reason = being AB is a straight line or supplementary

2) = angle AOB reason = being all the angles are of a straight line AB

3) = x + 2x+34 + 20 = 180 degree. reason being supplementary angle

4) = 42 degree

1) fill 180° in the blank

Reason :

Because AOB angles is half a page so it equals 180°

_________________________________

2)fill 180° in the blank

Reason :

AOE + EOF + FOB = AOB

And we have found that AOB angles is half a page so it equals 180°

3) 2x + 34 _ 180°

4) x = 42°

Then the best way to phrase it would be to jump right into the question without I need your help, because saying so makes it sound as though you have more of an urgent, sensitive, personal problem than a simple question or two (they might be a bit taken aback by the phrase).

However, if you have several questions (let's say more than 2), or if you just want to sound a bit more polite, you could preface the content with a phrase like I was wondering I you might be able to answer a few questions of mine, or, I have a few questions that I was hoping you might be able to help me with.

Answer:

y= -x + 10

Step-by-step explanation:

At 0 hours = Bob has 10 apples

At 4 hours = Bob has 6 apples

In 4 hours Bob has eaten 4 apples

Using linear graphs where y = the apples remaining and x = the hours passed

y = mx + c

We already know some coordinates:

(0,10) - 0 hours 10 apples remaining

(4,6) - 4 hours 6 apples remaining

c is the y intercept and m is the gradient

We already have the y intercept (where x = 0) which is (0,10)

So first part of our rule is done: y = mx + 10

The gradient is rise / run

Rise = -4 and Run = 4

-4/4 = -1

So the gradient is -1 and we add that to our rule

So final rule is y = -x + 10

Answer:

24GB

Step-by-step explanation:

75.99-59.99=16   This is how much extra money was paid.

16/4=4                   Divide this by the cost per GB.

20+4=24GB          Add the 20GB included in the plan.

Answer:

Step-by-step explanation:

75.99-59.99=16

$16 worth of GB used for that month

which means 16/4=4 GB extra were used that month beyond the 20 GB

so total GB usage for that month is 24 GB

Answer:

The selling price is $294

Step-by-step explanation:

5/100 (280)

0.05 * 280 = 14

5% of 280 equals 14.

To find the selling price we have to add the tax to the price.

$14 + $280 = $294

The selling price is $294

Answer:

-2265

Step-by-step explanation:

First, we replace x with 20.

[tex]f(20)=-5*20^2-13*20-5[/tex]

Then, we evaluate.

The * stands for multiplication.

[tex]f(20)=-5*20^2-13*20-5\\-5*400-260-5\\-2000-260-5\\-2265[/tex]

[tex]f(20) = - 5 \times {20}^{2} - 13 \times 20 - 5 \\ [/tex]

[tex]f(20) = - 5 \times 400 - 260 - 5[/tex]

[tex]f(20) = - 2000 - 260 - 5[/tex]

[tex]f(20) = - 2265[/tex]

Answer:

60 degrees

Step-by-step explanation:

40 degrees + 2y+20 degrees makes a straight angle. (from alternate interior angles postulate)

Thus, 2y+60 degrees = 180, or 2y = 120 degrees.

This means y = 60 degrees

Answer:

connor: Initial value is 200ft/ rate of change is 10

pilar: rate of change is -8/ initial value is 242

Step-by-step explanation:

so to figure out the initial value in a word problem, you need to see what it began or started with first and in the table to figure out the initial value, you need to see if there's a zero in the input and under the zero, the number in the output that's under 0 is the initial value. to find the rate of change in a word problem, if it says per, each, then it's the rate of change, Also to find the rate of change in a table you need to use this formula y²- y¹/x²-x¹ for example 234-242/1-0= -8/1 which is -8 for the slope. I hope my explanation helped. sorry if it's not clear

Answer: range: 3, domain: 4

Step-by-step explanation:

the range of a problem is basically the difference between the smallest and the largest y value. the largest y value here is 6 and the smallest is 3, so 6-3 = 3 -> 3 is your range! now for domain: the domain of a problem is the difference between the smallest and largest x value. the largest x value is 2 and the smallest is -2, so 2 - -2 = 4 -> the domain is 4! hope this helped!

Answer:

565+9x=250.......

Step-by-step explanation:

um i think this might be it

Answer:

he worked 35 hours

equation: p= $9x + 250

p is pay

x is hours worked

Step-by-step explanation:

we know that the pay was 565 so plug that into p: 565= 9x + 250

subtract 250 from both side to isolate the variable: 315= 9x

divide both sides by 9: x= 35
