Solve the equation:
8b = 5.6
Answer:
b = 0.7
Step-by-step explanation:
to solve the equation, you must isolate "b" so the variable is by itself,,
to do this, divide both sides of the equation by 8:
8b = 5.6
b = 5.6/8
now, simply divide 5.6 by 8 to get your answer,,
b = 5.6/8
b = 0.7
Estimate 154 divide 7
Answer:
22
Step-by-step explanation:
The result of 154 divided by 7 will be 22.
What is the rule of division?The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.
Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.
Since the given problem is not a large division. We can solve it by breaking 154 into two parts
______
7 / 154 \ 2 2
14
---------
1 4

---------
0
Therefore, 22 will come from dividing 154 by 7.

A chess piece is 15 centimeters tall, and its shadow is 13 centimeters long. How far away is the top of the chess piece from the end of its shadow? Round to the nearest tenth.
Answer:
19.8 cm
Step-by-step explanation:
Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm

cindy claims that 4^x/12^x=1/3
Answer:
what about the equation
Step-by-step explanation:
(05.02) In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40 degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y.
☁️My Answer☁️:
y = 90°
✧My Step-by-step explanation✧:
The angle x forms a straight line with the both the 50° angle and the 40° angle:
x + 50° + 40° = 180°
x = 90°
Which means…
y = x = 90°

Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf, and gave 1/3 of the rest to his brother for an art project. How many inches was the piece Anthony gave to his brother.
Answer:
8 inches
Step-by-step explanation:
Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf
Step 1
The amount of board he used to build the shelf is calculated as:
= 3/4 of 8 foot board
= 3/4 × 8 foot
= 6 foot board.
Step 2
The amount of board left after building the shelf = The rest =
8 foot - 6 foot
= 2 foot
Step 3
We are told that he gave 1/3 of the rest to his brother for an art project
The amount of board he give his brother for an art project =
1/3 × 2 foot
= 2/3 foot
Step 4
How many inches was the piece Anthony gave to his brother?
We convert 2/3 foot to inches
1 foot = 12 inches
2/3 foot = x inches
Cross Multiply
x inches = 2/3 foot × 12 inches
x inches = 8 inches
Therefore, Anthony gave his brother 8 inches of board.
