An object is traveling at a steady speed of 9 9/10 km/per hour about how long will it take the object to travel 5/1/10 km/per hour.

Answers

Answer:

0.52 km

Step-by-step explanation:

We are given that

Speed of object, v=[tex]9\frac{9}{10}km/h[/tex]

Speed of object, v=[tex]9+0.9=9.9km/h[/tex]

Distance travel by object, s=[tex]5\frac{1}{10}km[/tex]

Distance travel by object, s=[tex]5+0.1=5.1km[/tex]

We have to find the time taken by object to travel 5 1/10 km.

We know that

[tex]Time=\frac{Distance}{speed}[/tex]

Using the formula

Time taken by object to travel 5.1 km =[tex]\frac{5.1}{9.9} hr[/tex]

Time taken by object to travel 5.1 km=0.52 hr

Step-by-step explanation:

Using Trigonometry,

tan33° = Opposite/Adjacent = GF/DF.

Therefore GF = DF * tan33°

= 235tan33° = 152.6.

Angle GEF = Angle EDG + Angle DGE

= 33° + 34° = 67°. (Exterior Angle Theorem)

Using Trigonometry,

sin67° = Opposite/Hypotenuse = GF/EF.

Therefore EF = GF / sin67°

= 152.6 / sin67° = 165.8.

Hence the answer is the 1st option.

Answer:

the answer is A. GF =152.6 and EG=165.8

GF= 235*(tan(33))

EG= 152.6/(sin(67))

There are 16 cats and 14 dogs in a local animal shelter.

Which phrase describes a ratio relationship between the two quantities?

the number of dogs in the shelter compared to the number of cats in the shelter


the number of cats in the shelter compared to the number of cats in the shelter

the number of cats in the shelter compared to the number of dogs in the neighborhood

Answers

Answer:

This is by far the easiest question ever...Can you actually read and put effort into it before looking up all your answers next time? It literally says there are 16 CATS and 14 DOGS in a SHELTER. Its not A, because it did not mention rabbits. Its not C because it did not mention too much about cats, and it said dogs and cats not cats and cats. And its not D because we aint talking about a neighborhood. So..it is B. Easy, peasy, lemon squeezy!

Find the measure of interior angle C of hexagon OCEANS in which the
measure of the interior angles are:
O: 3x + 15, C: 2x + 30, E: 5x + 10, A: 2x + 55, N: 2x + 60, and S: x - 35.

Answers

Answer:

The measure of the interior angle C is [tex]108^{o}[/tex].

Step-by-step explanation:

Sum of angles in a polygon = (n - 2) x 180

where n is the number of sides of the polygon.

For a hexagon, n = 6. So that;

Sum of angles in a hexagon = (6 - 2) x 180

                                     = 4 x 180

                                     = [tex]720^{o}[/tex]

Sum of angles in a hexagon = [tex]720^{o}[/tex]

⇒ 3x + 15 + 2x + 30 + 5x + 10 + 2x + 55 + 2x + 60 + x - 35 = [tex]720^{o}[/tex]

15x + 135 = [tex]720^{o}[/tex]

15x = [tex]720^{o}[/tex] - 135

15x = 585

x = [tex]\frac{585}{15}[/tex]

  = [tex]39^{o}[/tex]

But,

C = 2x + 30

   = 2(39) + 30

   = 78 + 30

   = [tex]108^{o}[/tex]

The measure of the interior angle C is [tex]108^{o}[/tex].

After a power failure, the temperature in a freezer increased at an average rate of 3.5 °F per hour. The
total increase was 31.5 °F. Enter and solve an equation to find the number of hours until the power was
restored. Let x represent the number of hours it takes for the temperature to increase to 31.5 °F.

Answers

Answer:

equation: 3.5x=31.5

number of hours: 9

Step-by-step explanation:

31.5/3.5=9

Therefore,

x=9, x=number of hours, number of hours=9

I need help on knowing whether this is a solvable equation. Along with reasons why. HELP IF YOU CAN :))

Answers

To check if x = 9 is the solution, we need to replace every x with 9 and simplify

(3+x)/4 = 3

(3+9)/4 = 3

12/4 = 3

3 = 3

We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.

Multiply the second equation by 2

Solution: [tex](-\frac{45}{11},\frac{29}{11})[/tex]

Step-by-step explanation:

1) In order to use the elimination method to solve systems of equations, you must first multiply one or both of the equations so that the coefficients of a pair of terms with matching variables share the same number, but have opposite signs.

In this case, the y terms must fit that requirement. The y term in the first equation is 2y and the one in the second equation is -y. They already have opposite signs, one positive and other negative, so we just need -y to be -2y. So, in order to do that, multiply by 2.

2) After multiplying the whole second equation by 2, you will get [tex]8x - 2y = -38[/tex]. Now, add the the two equations together, eliminate the y terms, and isolate x to find its value.

3) Then, substitute that x value back into one of the equations to receive the y-value.

To better explain these steps, I attached pictures below.

A forest covers 52000 acres. A survey finds that 0.4​% of the forest is​ old-growth trees. How many acres of​ old-growth trees are​ there?

Answers

Given:

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

To find:

The area of old growth trees.

Solution:

We have,

Total forest area = 52000 acres

Area of old growth trees in the forest = 0.4%

Area of old growth trees is

[tex]Area=0.4\% \text{ of total forest area}[/tex]

[tex]Area=\dfrac{0.4}{100}\times 52000[/tex]

[tex]Area=0.4\times 520[/tex]

[tex]Area=208[/tex]

Therefore, the area of old growth trees is 208 acres.

Given

[tex]Expression = 40\% * 75[/tex]

[tex]Priya = \frac{2}{5} * 75[/tex]

Required

Is Priya correct?

We start by simplifying the expression.

[tex]Expression = 40\% * 75[/tex]

Express 40% as fraction

[tex]Expression = \frac{40}{100} * 75[/tex]

Simplify fraction: Divide numerator and denominator by 20

[tex]Expression = \frac{40/20}{100/20} * 75[/tex]

[tex]Expression = \frac{2}{5} * 75[/tex]

By comparing:

[tex]Expression = \frac{2}{5} * 75[/tex]

and

[tex]Priya = \frac{2}{5} * 75[/tex]

We can conclude that Priya is correct because:

[tex]40\% = \frac{2}{5}[/tex]
