Answers

Answer:

Step-by-step explanation:

if x=19, 19x3 =57 and 57+123=180 and straight angle = 180 so A

Answer:

X=19

Step-by-step explanation:

123 and 3x are supplementary/they equal 180 added together.

Let's solve your equation step-by-step.

123+3x=180

Step 1: Simplify both sides of the equation.

3x+123=180

Step 2: Subtract 123 from both sides.

3x+123−123=180−123

3x=57

Step 3: Divide both sides by 3.

3x/3 = 57/3

x=19

Have a splendid day.

Answer:

35/37

Step-by-step explanation:

In this question, we are to calculate the ratio that represents the cosine of angle O

Firstly, please check the attachment for the diagram of the triangle.

Mathematically, the trigonometric term Cos means the ratio of the length of the adjacent to that of the hypotenuse

The hypotenuse is the longest length which is 37 which represents the length ON

The side adjacent to angle O is the side OP which is 35

Thus, the ratio representing the cosine of angle O is 35/37

Clay works on a farm. He packaged eggs into
containers that hold 1 dozen eggs each. He filled
4 containers with white eggs and 5 containers
with brown eggs. How many eggs did Clay
collect? Hint: one dozen eggs = 12 eggs

Answers

Answer:

(4×12)+(5×12)

48+60

108 eggs total

Answer:

108

Step-by-step explanation:

Well considering the fact that the question is asking how many eggs did Clay collect in total, we can just multiply 4*12 (12 being how many eggs being in the container and 4 being the amount of containers) and multiply 5*12 to get a total of 108 eggs. Or you could just add both the amount of containers and multiply it by 12. Hope this helped :)

Cora uses 9.5 pints of blue paint and white paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls

Answers

Answer:

5.7 pints

Step-by-step explanation:

Total pints of paint used = 9.5 pints

Fraction of blue paint used = 2/5 ; while the rest is white paint

Amount od blue paint used :

2/5 * 9.5 = 3.8 pints

Amount of white paint used :

Total pints - blue pints used

9.5 pints - 3.8 pints

= 5.7 pints of white paint.

What is the kinetic energy of a 4 kg cart pushed at a rate of 0.5 m/s?

A. 0.5J

B. 2J

C. 4J

D. 8J​

Answers

Answer:

A. 0.5J

Step-by-step explanation:

[tex]K. E._{(cart)} = \frac{1}{2} m {v}^{2} \\ \\K. E._{(cart)} = \frac{1}{2} \times 4 \times (0.5)^{2} \\ \\ K. E._{(cart)} = 2 \times 0.25 \\ \\ K. E._{(cart)} = 0.5 \: J[/tex]

The kinetic energy of a 4 kg cart pushed at a rate of 0.5 m/s is 0.5 J.

Kinetic energy = 1 /2 mv²

where

m = mass

v = velocity

Therefore,

m = 4 kg

v = 0.5

Kinetic energy = 1 / 2 × 4 × 0.5²

kinetic energy = 1 / 2 × 4 × 0.25

kinetic energy = 1 / 2 × 1

kinetic energy =  1 /2  = 0.5 j

Davis has a thin box that is 5 inches wide. He wants to use the box to store markers that are 1/2 inch wide. If he lines up the markers side by side and uses the entire width of the box, how many markers can Davis fit in the box?

Answers

Answer:

10

Step-by-step explanation:

Given that :

Width of box, W = 5 inches

Width of marker to be stored in box = 1/2 inch

The number of 1/2 inch marker which can be stored in box is :

Width of box ÷ width of marker to be stored in box

5 inches ÷ 1/2 inches

5 / 0.5

= 10

Hence, Ten 1/2-inch width marker can be stored in the box
