8 divided by 5.2
that’s all it takes
Answer:
0.65
Step-by-step explanation:
Since we have given that
Cost of 8 pencils = 5.20
We need to find the cost of 1 pencil.
For this we'll use the unitary method,
5.20 divided by 8 = 0.65
A carpenter cut a board that was 10 feet long into two pieces. The longer piece is 2 feet longer than three times the length of the shorter piece. What is the length of each piece?
Answer:
shorter piece: 2 feet
longer piece: 8 feet
Step-by-step explanation:
let the shorter piece be x
then the longer piece will be 3x + 2
if they join together:
3x + 2 + x = 104x + 2 = 104x = 10 -24x = 8x = 2Longer piece:
3x + 23(2)+28 feetAnswer:
x+3x+2=10
4x=10-2
4x=8
x=8/4
x=2 ft. for the shorter piece./
3*2+2=6+2=8 ft. for the longer piece.
Proof:
8+2=10
10=10

The area of a circle is 61.2cm2.
Find the length of the radius rounded to 2 DP.
Answer:
4.41 cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
61.2 = pi r^2
Using 3.14 for pi
61.2 / 3.14 = r^2
19.49044586 = r^2
Take the square root of each side
sqrt( 19.49044586) = sqrt(r^2)
4.414798507 = r
To 2 decimal places
4.41 = r

Answer:
5/4
Explanation:
coordinates given (0,0) and (8,10)
How to find unit rate?
use this formula:
(y2-y1)/(x2-x1)
using the formula:
→(10-0)/(8-0)
→ 10/8
→ 5/4
→ 1.25
Answer:
5/4 cm/s
Step-by-step explanation:
The gradient (slope) of the line is equal to the speed of the object.
Gradient = change in y ÷ change in x
Using the two given points (0, 0) and (8, 10):
⇒ speed = (10 - 0) ÷ (8 - 0) = 5/4 cm/s
The isosceles triangle has a perimeter of 7. 5 m. Which equation can be used to find the value of x if the shortest side, y, measures 2. 1 m? 2 x minus 2. 1 equals 7. 5 4. 2 plus y equals 7. 5 y minus 4. 2 equals 7. 5 2. 1 plus 2 x equals 7. 5.
Using the perimeter formula of the Isosceles triangle the equation 2x + 2.1 = 7.5 is derived. The correct option is D.
What is the isosceles triangle?Triangle is a polygon that has three sides. The sum of the angle of the triangle is 180 degrees. The two sides of the triangle are equal.
Given
The isosceles triangle has a perimeter of 7.5 m.
We know the perimeter of the Isosceles triangle.
Perimeter = Sum of all sides of the triangle
Let the sides be x and y and
And let y be the shortest side.
For y = 2.1 m, the equation will be
[tex]\rm Perimeter = x + x +y\\[/tex]
On simplifying the equation, we get
2x + 2.1 = 7.5
The required equation is 2x + 2.1 = 7.5.
Thus, option D is correct.

Answer:
18 Outcomes
Step-by-step explanation:
When the quarter is tossed, there is a total of 2 outcomes:
Heads or Tails
When a letter from SNOWFLAKE is chosen, there is a total of 9 outcomes:
S,N,O,W,F,L,A,K,E
To find out how many outcomes are possible, we multiply the 2:
2×9=18
18 Outcomes
Question
Is it possible to construct a triangle with side lengths of 3, 6, and 9 units? If not, explain why not
Answer:
No
Step-by-step explanation:
No.
The triangle inequality theorem says that ANY two sides of a triangle MUST be greater than the third side.
In this case 3+6 is equivalent to 9 (it wouldn't be a triangle; just be a straight line), NOT greater, therefore is is not possible to construct a triangle with the given side lengths.

Q1: A factory produces candy bars, with mean weight 5 grams. After the machines were updated with new tech, a worker worries the candy bars are now lighter on average. To test this theory, the worker collects a random sample of candy bars and measures their mean weight. Identify the null and alternative hypotheses in this situation.
The null hypothesis in this situation is the mean weight of the candy bars is not lighter.
The alternative hypothesis in this situation is the mean weight of the candy bars is lighter.
What is a hypothesis?
A hypothesis is an idea that gives a temporary explanation to a phenomena which would be proved or disapproved by carrying out an experiment .
The null hypothesis states that there is no relationship between the population parameters. It is known as the true hypothesis. The alternative hypothesis states that there is a relationship between the population parameters.
