A truck travels 205 miles in 3 1/2

hours.
To the nearest tenth, what is the average speed of the delivery truck?
Enter your answer in the box.

Answers

If you would like to know the average speed of the delivery truck, you can calculate this using the following steps:

205 miles ... 3 1/2 hours = 7/2 hours
x miles = ? ... 1 hour

205 * 1 = 7/2 * x
205 = 7/2 * x
x = 205 * 2/7
x = 58.6 miles

The correct result would be 58.6 miles per hour.

avg speed = total distance ÷ total time

205 ÷ 3.5 = 58.571...

round to nearest 10th 58.6 mph

Point X is the incenter of ΔABC. Triangle A B C has point X as its incenter. Lines are drawn from the points of the triangle to point X. Lines are drawn from point X to the sides of the triangle to form right angles. Line segments X F, X G, and X E are formed. If EX = 4z + 1, XF = 2z + 7, and mABC = 44°, find the following measures.

What is the right-angle triangle?

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given, Point X is the incenter of ΔABC. Triangle A B C has point X as its incenter. Lines are drawn from the points of the triangle to point X.

Also Given :

EX = 4z + 1 and XF = 2z + 7

Solution :

Take EX and XF equal time each other and then solve for z and then you will get GX because EX = XF = GX is congruent.

EX = XF

4z + 1 = 2z + 7

2z = 6

z = 3

As, EX = XF = GX

EX = 4(3) + 1

EX = 13

Thus, GX = 13 ------ ( EX = XF = GX )

To find the ∠ABX, divide ∠ABC them by 2 you will get

∠ABX = 22°

Therefore, The Measurement of Line GX will be 13 and ∠ABX will be 22°.

which situation would be represented by a discrete probability distribution? a) the weight of fire fighters b) the overall average of a math class c) the ages of all the students in a class d) the number of students who could distinguish between two different soft drinks

Answers

A discrete variable is a variable which may take only certain discrete values; for example the number of people in a household is a discrete variable which may have the value 1, 2, 3, etc. but cannot have intermediate values such as 1.473 or 3.732.
Choice d) can be represented by a discrete probability distribution, the other choices cannot be so represented.

A school has $ 15,000 to spend on computer monitors the school plans to purchase 200 monitors for $89 each a teacher completes the calculations below and concludes that the has enough money to buy the monitors 200 times 89 = 200 times 8 + 200 times 9 = 1,600 +1,800 =3,400

Answers

Answer:

They cannot afford the monitors

Step-by-step explanation:

Given that the cost of a monitor is $89

and the school is willing to buy up to 200 monitors

We can calculate the total cost of all the 200 monitors as

200*89= $17,800

Given that the school only has $ 15,000 to spend on the monitor

they cannot afford the amount as they still have a deficit of $2,800

Mary deposited $350 in a bank account that promises 2.8 percent interest compounded continuously. Approximately how many years will it take to reach a balance of $500?

Answers

Answer:

The time taken to reach the balance is approximately 13 years.

Step-by-step explanation:

Given : Mary deposited $350 in a bank account that promises 2.8 percent interest compounded continuously.

To find : How many years will it take to reach a balance of $500?

Solution :

The formula of compounded continuously is

$A=Pe^(rt)$

Where, A is the amount A=$500

P is the principal P=$350

r is the interest rate r=2.8%=0.028

t is the time in year.

Substitute the values in the formula,

$500=350* e^(0.028* t)$

$(500)/(350)=e^(0.028* t)$

$1.42=e^(0.028* t)$

Taking log both side,

$\ln 1.42=0.028* t$

$0.356=0.028* t$

$t=(0.356)/(0.028)$

$t=12.71$

The time taken to reach the balance is approximately 13 years.

You use the formula
A= Pe^rt for continuously compounded interest.
500=350e^(.028*t)
Divide both sides by 350
(10/7)=e^(.028t)
Take the natural log of both sides to clear the e.
Ln (10/7)=.028t
Divide both sides by .028
Ln (10/7)/.028 =t
12.75 years
