Tom drives 200 miles in 4 hours.
He drives the first 32 miles at an average speed of 64 mph
Work out his average speed for the rest of the journey, in mph.
Please help??

Answers

His average speed for the rest of the journey was of 48mph.

if tom is driving 200 miles in 4 hours... and drives the first 32 miles in half an hour... his speed for the rest of the trip would most likely be 48 mph because 3.5 hours are left and 168 miles are left and when you divide that it comes out to 48.

Angle O=64

Side m=7.3159882(rounded if needed)

Side n=16.68902(round if needed)

We are given

Angle M which equal 26.

Angle N equals 90 degrees

Side MN which equal 15.

We are asked to find all the missing elements of the triangle.

Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.

[tex]90 + 26 + x = 180[/tex]

[tex]116 + x = 180[/tex]

[tex]x = 64[/tex]

Angle O=64 degrees

We can find side m by doing law of sines.

[tex] \frac{on}{ \sin(26) } = \frac{mn}{ \sin(64) } [/tex]

[tex] \frac{on}{ \sin(26) } = \frac{15}{ \sin(64) } [/tex]

[tex]on = \frac{15}{ \sin(64) } \times \sin(26) [/tex]

which is 7.315(round if neeeded).

We can find side n using pythagorean theorem,

[tex] {15}^{2} + {7.3}^{2} = {n}^{2} [/tex]

[tex]225 + 53.29 = {n}^{2} [/tex]

[tex] \sqrt{278.29} [/tex]

Side n=16.689(round if needed)

Leg: 28m; hypotenuse: 37m

Answers

Answer:

24.2

Step-by-step explanation:

Leg: 28m

Hypotenuse: 37m

To find the missing leg, use the following formula:

b = √[tex]c^{2} - a^{2}[/tex]

b = √[tex]37^{2} - 28^{2}[/tex]

b = √1369 - 784

b = √585

b = 24.18677

Round to the nearest tenth

24.18677 = 24.2

Kiran has $100 saved in a bank account. (The account doesn’t earn interest.) He asked Clare to help him figure out how much he could take out each month if he needs to have at least $25 in the account a year from now.

Answers

the answer would be 650

He could take out $6.25 for each month and at the end $25 also left in his account.

What is an expression?

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the data given in the question,

The total amount Kiran is having in the bank = $100

He needs to have at least $25 in the account at the end of the year.

So, the money he can spend in a year = $100 - $25 = $75

1 year = 12 months

So, the amount of money spent per month will be,

75/12 = $6.25

Determine the length of the line segment with the end points at (9, 6) and (-12, 6).

Answers

Answer:

Step-by-step explanation:

You are given two points whose y values are the same. There is no need to use the distance formula. The x values alone will give you the length of the line.

to get to the y axis you have to go 12 units to the right.

To get from the y axis to 9, you have to go 9 more units to the right.

The total is 9 + 12 = 21

If you insist to see this done with the formula, it would look like this.

d = sqrt( y2 - y1)^2 + (x2 - x1)^2 )

y2 = 6

y1 = 6

x2 = -12

x1 = 9

d = sqrt ( (6 - 6)^2 + (-12 - 9)^2 )

d = sqrt( 0 + ( -21 )^2 )

d = sqrt( 441)

d = 21 the same thing you got just be reasoning it out.

The first method works only if either both xs are the same or both ys are the same.

Answer:

x = 3.6

Step-by-step explanation:

It can be helpful to write down corresponding sides and their measures.

AB = 5, PQ = 6

BC = 3, QR = x

CD = 2, RS = 2.4

DA = 4, SP = 4.8

Then you can look for easy ways to find x. You can tell from this table that all of the values in PQRS are 6/5 = 1.2 times the corresponding values in ABCD.

Then ...

QR = 1.2×BC = 1.2×3

QR = x = 3.6

_____

Other ways you can figure x are ...

x/BC = PQ/AB

x = (BC)(PQ/AB) = 3(6/5) = 3.6 . . . . the method we used

x/RS = BC/CD

x = 2.4(3/2) = 3.6

x/SP = BC/DA

x = 4.8(3/4) = 3.6

Heather has a rectangular yard, she measures it and finds out it is 24 1/2 feet long by 12 4/5 feet wide. She wants to know how many square feet of sod she will need to cover her yard. How much did will she need and if each square inch of sod cost 65 cents how much will she pay to cover her yard?

Answers

Answer: $2,446.08

Step-by-step explanation:

Lets convert the length and width into decimal form so it's easier to understand.

24 1/2= 24.5

12 4/5= 12.8

Now we must multiply to get the area. 24.5x12. 8= 313. 6 ft

Each square inch costs .65 so we must multiply .65 by 12 to see how much a foot costs. 12x0.65= 7.8

Now that we know how much each foot cost lets multiply 313.6 by 7.8. 313.6x 7.8= $2446.08
