Mr. Martinez's limo drove 15 miles south to Candy Land for some delicious gumdrops, then 5 miles east to Chuck E. Cheese for some scrumptious pizza. How far is Mr. Martinez from his starting point? Round your answer to the nearest tenth if necessary.

Answers

Answer:

15.8 miles

Step-by-step explanation:

Given that:

Distance driven south = 15 miles

Distance driven east = 5 miles

How far is Mr. Martinez from his starting point?

Using Pythagoras :

Distance from starting point(d) :

d = √(15)² + (5)²

d = √225 + 25

d = √250

d = 15.811388

d = 15.8 miles

Felipe has a recipe for peanut butter dog treats. What is the ratio of cups of flour to tablespoons of peanut butter if Felipe makes 3 batches of dog treats? Show your work.

(Ingredient). (amount)
Peanut butter 4 tbsp
Flour. 1 cup
Egg. 1
Water. 2 tbsp


Solution:

Answers

3 cups : 12 tbsp? I think is the right answer

The ratio of cups of flour to tablespoons of peanut butter if Felipe makes 3 batches of dog treats is, 1/4

What is the ratio?

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

Felipe makes 3 batches of dog treats

The recipe for peanut butter dog treats,

(Ingredient)                 (amount)

Peanut butter              4 tbsp

Flour                             1 cup

Egg                               1

Water                           2 tbsp

For 3 batches

Peanut butter required = 3 × required for one batch

                                       = 3 × 4

                                       =  12 tbsp

Flour Required               =  3 × required for one batch

                                       =  3 × 1

                                       =  3

the ratio of cups of flour to tablespoons of peanut butter =  3/12

                                                                                                =  1/4

Hence, the ratio is 1/4

Determine the value of x in the diagram below

Answers

Answer:

x =32

Step-by-step explanation:

create equation

180 = 3x + 20 + 2x

combine like terms

180= 3x + 20 + 2x

180=5x + 20

subtract 20 from both sides of the equation

180=5x + 20

180-20= 5x +20 -20

simplify

160= 5x

divided both sides by 5

160/5=5x/5

solution

if cos(x)=-1/4 and tan(x)<0 what is sin(2x)​

Answers

By definition of tangent,

tan(x) = sin(x) / cos(x)

so if tan(x) < 0, and we're given cos(x) = -1/4 < 0, then it follows that sin(x) > 0.

Recall the Pythagorean identity:

cos²(x) + sin²(x) = 1   →   sin(x) = + √(1 - cos²(x))

Then

sin(x) = √(1 - (-1/4)²) = √(15/16) = √(15)/4

Recall the double angle identity:

sin(2x) = 2 sin(x) cos(x)

Then

sin(2x) = 2 • √(15)/4 • (-1/4) = -2√(15)/16 = -√(15)/8

the ratio of 5 more than a number to 20 less than that number is 8:3. What is the number?

Answers

Answer:

35

Step-by-step explanation:

Let the number  = y ;

  5 more than the number  = y + 5

  20 less than that number  = y  - 20

Ratio  = 8:3;

Solution:

 Ratio of the number:

                   [tex]\frac{y + 5}{ y -20}[/tex]   = [tex]\frac{8}{3}[/tex]

Now cross multiply and solve for y;

          3(y+5)  = 8(y-20)

            3y + 15  = 8y - 160

            3y - 8y  = -160 - 15

                -5y  = -175

                    y  = 35
