Nirvany went on a 65,000 m hike. She divided the distance traveled evenly over 5 days. Approximately how many miles did Nirvany walk each day?

Answers

Answer:

13000m

Step-by-step explanation:

Given data

Total distance travelled= 65,000

Number of days= 5 days

Hence the distance covered per day is

= 65,000/5

=13000m

Therefore the distance covered per day is 13000m

A group of friends went to lunch. The bill, before sales tax and tip was $35.55. A sale tax of 6% was added. The group then tipped 15% on the amount after the sales tax was added. What was the amount, in dollars, of the total cost?

Answers

I did the math and I think it is $62.20??

Answer:

about $43.34 rounded to the nearest tenth

Step-by-step explanation:

First add 6% of 35.55 to 35.55

35.55x1.06=37.683

This is the price after tax

Next add the percentage of tax to 37.683

37.683x1.15=43.335

Rounded to the nearest cent and your final answer is $43.34

One of the legs of a right triangle measures 6 cm and its hypotenuse measures 10 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.

Answers

Answer:

let base = 6cm

perpendicular =x cm

hypotenuse =10cm

by using Pythagoras law

hypotenuse ²=perpendicular ²+base²

10²=x²+6²

100-36=x²

x=√64=8cm

the measure of the other leg is 8cm

The measure of the other leg of the right triangle is equal to 8 cm.

Let the other leg of the right triangle be the opposite side.

Given the following data:

Adjacent = 6 cmHypotenuse = 10 cm

To find the measure of the other leg, we would apply Pythagorean's theorem:

Mathematically, Pythagorean's theorem is given by the formula;

[tex]Hypotenuse^2 = opposite^2 + adjacent^2[/tex]

Substituting the given parameters into the formula, we have;

[tex]10^2 = opposite^2+6^2\\\\100= opposite^2+36\\\\Opposite^2=100-36\\\\Opposite^2=64\\\\Opposite=\sqrt{64}[/tex]

Opposite = 8 cm

Answers

phytagoras theorem
a^2 + b^2 = c^2
where c is the hypotenuse; angle between a and b is 90 degrees.
In this case, c = 10 ft
Say a = 6 ft
then find b
6^2 + b^2 = 10^2
b^2 = 100 - 36 = 64
b = 8 ft
So yes, it will reach over 7 feet

Helpppp pleaseeeee and could you put an explenation??? pleaseeee

Answers

Answer:

Step-by-step explanation:

The angles would be supplementary

45 + 5x + 35 = 180

5x + 80 = 180

5x = 100

x = 20

To find out why they are supplementary, refer to the transversal below

∠3 = ∠7 (corresponding angles)

∠8 = 180 - ∠7 (supplementary angles)

And since ∠7 = ∠3...

∠8 = 180 - ∠3 which is why (in the problem) those two angles are supplementary (adding to 180 degrees)

a^2-36=5a

A. {4,-9}
B. {5+√61/2, 5-√61/2}
C. No solution
D. {9,-4}

Answers

Answer:

Step-by-step explanation:

Given

a² - 36 = 5a ( subtract 5a from both sides )

a² - 5a - 36 = 0

Consider the factors of the constant term (- 36) which sum to give the coefficient of the a- term (- 5)

The factors are - 9 and + 4 , since

- 9 × + 4 = - 36 and - 9 + 4 = - 5 , then

(a - 9)(a + 4) = 0 ← in factored form

Equate each factor to zero and solve for a

a - 9 = 0 ⇒ a = 9

a + 4 = 0 ⇒ a = - 4

solution is { - 9, 4 } → D

What is linear Equation?

When graphed, a linear equation always produces a straight line because it is an algebraic equation with each term having an exponent of 1. It is referred to as a "linear equation" for this reason.

One-variable linear equations and two-variable linear equations exist.

Given

points on free throws = 1

points on 4 free throws = 4x1 = 4

and points on 2 three point shot = 2x3 = 6

total points are 4 + 6 = 10

and if she made x free throws then points are = 1x

and for y three point shots = 3y

total points for x free and y three point shots

x + 3y

Hence the points are 10 and x + 3y.
