Bobby is 28cm shorter than Daniel. Roy is 19 cm taller than Daniel. Find the difference in height between Roy and Bobby.

Answers

Answer 1

Answer:

There is a 47cm difference between the two....

So you just added 28cm to 19cm to get 47cm....

Because 19-(-28) is 19 + 28.

Hope this helps :D

Answer:

x ≈ 11.1

Step-by-step explanation:

Using the sine ratio in the right triangle

sin59° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{13}[/tex] ( multiply both sides by 13 )

13 × sin59° = x , then

x ≈ 11.1 ( to the nearest tenth )

Answer:

11.14 to nearest hundredth.

Step-by-step explanation:

sine = opposite side/ hypotenuse so here we have:

sin 59 = x/13

x = 13 sin 59

= 11.143

Answer:

sorry but I think your question is not correct

1. Invert and multiply.
x − 11 • 7 = −1
x − 11 • 7 = −1

2. Simplify 11×7 to 77.
x − 77 = −1

3. Add 77 to both sides.
x = −1 + 77

4. Simplify −1 + 77 to 76.
x=76

A class has 12 girls and 18 boys. What is the probability that a boy raises his hand and asks to go to the bathroom given a girl already left the room to go to the bathroom?

Answers

Answer:

The answer is [tex]\frac{18}{29}[/tex]

Explanation:-

Total number of students = 12 + 18 = 30

Total number of students after one girl left = 29

Number of boys = 18

Probability that a boy raises his hand and asks to go to the bathroom =

Number of boys divided by total number of students

[tex]\frac{18}{29}[/tex]

A water container in the shape of a cone has a height of 5 inches and a diameter of 3.5 inches.
Enter an equation in the first blank box and a number in the second blank box to complete the statements about the
water container ___.
A. The formula to calculate the container's volume, V, with the given measurements is
B. The container can hold approximately ___ cubic inches of water. Round your answer to the nearest hundreth.

Answers

Answer

A. The formula to calculate the container's volume, V, with the given measurements is ⅓ π(1.25²)5.

B. The container can hold approximately 8.177 cubic inches of water. Round your answer to the nearest hundredth.

Step-by-Step Explanation

A. The formula to calculate any cone's volume is ⅓ πr²h. Replace the variables with the actual values of the cone. r stands for the cone base's radius, or half of the diameter. Because the diameter is 3.5, the radius is 1.25, or half of it. The h stands for the height of the cone. Now we can plug in the values. Our answer for this part is ⅓ π(1.25²)5.

B. Now to solve our equation. [tex]1.25^2[/tex] is equal to 1.5625. Now, multiply by the height. 1.5625 x 5 is equal to 7.8125. We now multiply by [tex]\pi[/tex]. We'll use 3.14 to shorten the answer a bit. Multiply 7.8125 by 3.14 and you'll get 24.53125. Last but not least, divide this by 3 (or multiply by [tex]\frac{1}{3}[/tex]). [tex]\frac{24.53125}{3}[/tex] = 8.1770833333... We now must round this to the nearest hundredth. This makes our final answer 8.177 [tex]in^3[/tex].

What is the definition of the slope of a line?

Answers

The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.

In mathematics the slope or gradient of a line is a number that describes both the direction and the steepness of the line

Should you use Sine, Cosine, Tangent to solve the following problem

Answers

Answer:

tangent

Step-by-step explanation:

SOH( sin = opposite/hypotenuse)

CAH(cosine = adjacent/hypotenuse)

TOA(tan = opposite/adjacent)

you are trying to find x and the numbers given to you are opposite of x and adjacent to x. that means you need to use toa

We will use Tangent of the angle.

What is Tangent of the angle?

In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

Given that, a right triangle, with perpendicular = x and an acute angle = 28° and base = 14

Since, we know that, tan α = opposite side / adjacent side

In other two trigonometric ratios, we need the length of hypotenuse, which is not given.

Hence, We will use the Tangent of the angle.
