Please help!!!!!!!!!!!!!!!!!

Answer:

sin = p/h.

cos=b/h

tan =p/b

pythagoras

h^2=p^2+b^2

here

h=5

p= 3

b=4

Answer:

sin(A)=3/5

cos(A)=4/5

tan(A)=3/4

Step-by-step explanation:

length of the other side is 5 using pythagorean theorem

sin= opposite/hypotenuse

cos= adjacent/hypotenuse

tan= opposite/adjacent

opposite angle A- 3

adjacent angle A- 4

hypotenuse- 5

Answer:

The plans will be equal at 160 minutes of call

Step-by-step explanation:

1st plan: y = 0.14x + 30

2nd plan: y = 0.19x + 22

0.14x + 30 = 0.19x + 22

Subtract 0.19x from both sides;

-0.05x + 30 = 22

Subtract 30 from both sides;

-0.05x = -8

Divide both sides by -0.05

x = 160

Answer:

[tex]Gallons = 2.305[/tex]

Step-by-step explanation:

Given

Rate = 130.16 miles for 5 gallons

Required

Number of gallons used for a journey of 60 miles

The rate in miles per gallon is calculated as:

[tex]Rate = \frac{Distance}{Gallons}[/tex]

When distance = 130.16 and gallons = 5, we have:

[tex]Rate = \frac{130.16}{5}[/tex]

[tex]Rate = 26.032[/tex]

When distance = 60 miles.

Substitute 60 for distance and 26.032 for rate in [tex]Rate = \frac{Distance}{Gallons}[/tex]

[tex]26.032 = \frac{60}{Gallons}[/tex]

Cross Multiply

[tex]Gallons * 26.032 = 60[/tex]

[tex]Gallons = \frac{60}{26.032}[/tex]

[tex]Gallons = 2.305[/tex] --- approximated

Step-by-step explanation:

The solution of `2x + y + z = 1 , x-2y-3z = 1 , 3x +2y +4z=5` is 1)1,2,3 2) 1,2,-3 3) 1.-3.2 4)...

This is a 2-step equation. We will solve it in 2 steps.

[tex]-2x + 1 = -6\\\\-2x = -7\\\\x = \frac{7}{2}[/tex]

The solution for this equation is x = [tex]\frac{7}{2}[/tex].

Answer:

$18.15

Step-by-step explanation:

Here, we want to find the difference between the two values

what we do here simply is to subtract the second from the first

Mathematically we have this as;

36-17.85 = $18.15

All you have to do is take the value listed above for g(x) and set it equal to 16.

-3x+1=16.

Subtract 1 from both sides

-3x=15

divide both sides by -3

x=-5

Step-by-step explanation:

Let x be the number of pages that were skimmed through.

Time taken to skim through = 10 * (x/15) = 2/3 x min.

Time taken to read through = 15 * [(275-x)/10] = 1.5(275-x) min.

We have 2/3 x + 1.5(275-x) = 350.

Therefore 412.5 - 5/6 x = 350 and x = 75.

Answer:8pages

Step-by-step explanation:

10minutes/350minutes×275=7.85~8pages

Answer:

4g + 4

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Length = 0.7g + 2

Width = 1.3g

Plug in the values into the equation

Perimeter = 2(0.7g + 2 + 1.3g)

Perimeter = 2(0.7g + 1.3g + 2)

Perimeter = 2(2g + 2)

= 2*2g + 2*2

Perimeter = 4g + 4

Answer:

The value of x is 67

Step-by-step explanation:

In the given figure

∵ One side of the triangle is extended to form an exterior angle of 113°

∵ The angle of 113° and the angle of x° are adjacent angles

∵ They formed a line (the side is extended)

→ That means they formed a pair of linear angles

∴ The angle of 113° and the angle of x° formed a pair of linear angles

∵ The measure of the pair of linear angles = 180°

∴ 113° + x° = 180

→ Subtract 113 from both sides

∵ 113 - 113 + x = 180 - 113

∴ x = 67

∴ The value of x is 67

Answer: 3.25

Step-by-step explanation:

Sarah made a.mistaje when she was reducing 26 ÷ 8. It should be noted that 2 is a common factor to 26 and 8. Therefore 26÷2 = 13 and not 14 that Sarah wrote. Sarah should have written 13 ÷ 4 and not 14 ÷ 4.

26 ÷ 8 in decimal will give us 3.25
