Caleb is participating in a walk-a-thon. His goal is to walk as far as possible over an 8-hour period.

For the first 3 hours, he keeps a steady pace of 2 miles per hour.

He then stops walking while he takes a 1-hour break for lunch.

It's too short. Write at least 20 characters to explain it well.

the delivered price of leah st clairs new car is 22450. she makes a 2800 down payment and pays the balance in 36 monthly payment

Degger [83]

Answer:

Total amount paid for the Car=$24,832

Finance Charge=$2,382

Step-by-step explanation:

Down payment on the Car=$2800

Number of Monthly Installments=36

Amount Paid Per Installment=$612

Total Monthly Installment Paid=36*$612=$22032

Therefore, the Total Amount Paid for the Car=Down Payment+Total Installmental Payment=2800+22032=$24,832

Next, we determine the finance charge.

Finance Charge=Total Amount Paid for the Car - Delivered Price of the Car

=24832-22450

=$2,382

Therefore:

Total amount paid for the Car=$24,832

Finance Charge=$2,382

Find the slope and reduce p=(-2,-1) q=(6,5)

Delicious77 [7]

Answer:

3/4

Step-by-step explanation:

Given two points , we find the slope using the formula

m = (y2-y1)/(x2-x1)

= ( 5 - -1)/ ( 6 - -2)

= (5+1)/( 6+2)

= 6/8

= 3/4

Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.

AlekseyPX

Answer:

$\frac{5\sqrt{2} }{2}$

Step-by-step explanation:

$x: \text{opposite side of the angle of 45\º}$

$5: \text{hypotenuse of the right triangle}$

$\sin(\theta)=\frac{\text{opp}}{\text{hyp}} \Rightarrow \sin(45\º)=\frac{x}{5}$

$\text{Once }\sin(45\º)=\frac{\sqrt{2} }{2}$

$\frac{\sqrt{2} }{2} =\frac{x}{5} \Rightarrow 2x=5\sqrt{2} \Rightarrow x=\frac{5\sqrt{2} }{2}$

You can just remember that 5 is the diagonal of a square of side length x.

$5=x\sqrt{2} \Rightarrow x=\frac{5}{\sqrt{2} } \Rightarrow x=\frac{5}{\sqrt{2} } \cdot \frac{\sqrt{2} }{\sqrt{2} } = \frac{5\sqrt{2} }{2}$

What is the length of x in the triangle shown

ivann1987 [24]

Since this is a right triangle the angle opposite the side 17 is also 45°

So this can be solved in two ways...

The Law of sines...

x/sin90=17/sin45

x=17/sin45

x≈24.04 to nearest hundredth

or by realizing that both sides are 17 because they are both opposite 45° angles then the hypotenuse x is

x=√(2*17^2)

x=√578

x≈24.04
