7.6 cm
Diagram NOT
accurately drawn
A circle has a radius of 7.6 cm.
Work out the area of the circle.
Give your answer correct to 3 significant figures.
Answer:
181cm²
Step-by-step explanation:
Given
Radius of a circle = 7.6cm
Area of the circle = \pi r²
Substitute
Area of the circle = 3.14(7.6)²
Area of the circle = 3.14(57.76)
Area of the circle = 181.3664cm²
Area of the circle to 3sf is 181cm²
Two groups of hikers leave the same camp heading in opposite directions. The first group travels 4 miles north and 3 miles east. The second group travels 2 miles south and 5 miles west.
a. Draw the situation in the coordinate plane using a right triangle. Use the origin as the camp location, and let each unit represent 1 mile. For example, the point (2, 1) would represent 2 miles east and 1 mile north of the camp.
b. Determine the distance between the two groups after the hikes.
Question 2
The distance between the two groups is __ miles.

Solve using the substitution method. 3x +2y= 19 xy= 15
Answer:
when x = 3 1/3, y = 4.5
or
when x =3 , y = 5
Step-by-step explanation:
Here, we want to solve using substitution
xy = 15
let x = 15/y
Put this into the first equation;
3(15/y) + 2y = 19
45/y + 2y = 19
Multiply through by y
45 + 2y^2 = 19y
2y^2 -19y + 45 = 0
2y^2 - 10y - 9y + 45 = 0
2y(y-5) -9(y-5) = 0
(2y-9)(y-5) = 0
2y-9 = 0
or y-5 = 0
2y = 9 or y = 5
y = 9/2 or y = 5
y = 4.5 or y = 5
Recall;
x = 15/y
x = 15/4.5 or x = 15/5
x = 3 1/3 or x = 3

Step-by-step explanation:
Adam has 3 coins in his pocket and they are all different from each other. Ben has 3 coins in his pocket and they are all the same as each other. Adam has half as much money as Ben.
What are the coins they each have?
Answer:
The possible coins are:
P = penny = $0.01
N = nickel = $0.05
D = dime = $0.10
Q = quarter = $0.25
H = half dollar = $0.50
We know that Adam has 3 coins in his pocket, and all of them are different, then the money that Adam has can be represented with (A + B + C)
Behn has 3 coins, and all of them are the same, then if his coin has a value X, he has a total of 3*X
We know that Adam has half as much money as Ben, this can be written as:
(A + B + C) = 3*X/2
The easier way to solve this, is to play with different values of X, and see if we can find the values of A, B and C.
For example, if X = $0.10
then:
(A + B + C) = $0.10*(3/2) = $0.15
We can find 3 different value of coins for this equation? No, we cant, so X = $0.10 is also discarded.
if x = $0.50 then:
(A + B + C) = (3/2)*$0.50 = $0.75
Here we could have:
A = $0.50
B = $0.25
then: A + B = $0.75
But we still have the coin C.
If we take X = $0.25 then:
(A + B + C) = (3/2)*$0.25 = $0.375
We could round the right part to $0.40
then the coins in the left part would be:
A = $0.25
B = $0.10
C = $0.05
A + B + C = $0.25 + $0.10 + $0.05 = $0.40
This is a strech, but is the only thing we can make with the given problem.
3(x + 1) + 5(2x –5)–2(x –2)= 4
solve
Answer:
x=2
Step-by-step explanation:
3x+3+10x-25-2x+4=4
11x-18=4
11x=4+18
11x=22
x=22/11
x=2
Answer:
x = 2
Step-by-step explanation:
3(x + 1) + 5(2x –5)–2(x –2)= 4
First, let's distribute the numbers across the parentheses through multiplication.
3x + 3 + 10x - 25 - 2x + 4 = 4
Combine like terms.
11x - 18 = 4
Add 18 to both sides to isolate x.
11x = 22
Divide both sides by 11 to isolate x further.
x = 2
Check by plugging 2 back into the equation.
3(2 + 1) + 5(2(2) - 5) - 2(2 - 2) = 4
3(3) + 5(4 - 5) - 2(0) = 4
9 + 5(-1) - 0 = 4
9 - 5 = 4
4 = 4
Your answer is correct.

f(x) = -x² + x + 14
Find f (2)
Answer:
Step-by-step explanation:
f(2) = -2^2 + 2 + 14 = -4 + 2 + 14 = 12
Answer:
f(2) = 20
Step-by-step explanation:
f(x) = -x^2 + x + 14
f(2) = (2)^2 + (2) + 14
f(2) = 4 + 2 + 14
f(2) = 20

(a) Work out the value of I when x = 5 and y=-7
Note: Consider the dependent variable is T instead of I, and we need to find the value of T when x=5 and y=-7.
Given:
[tex]T=3x+4y[/tex]
To find:
The value of T when x=5 and y=-7.
Solution:
We have,
[tex]T=3x+4y[/tex]
Putting x=5 and y=-7, we get
[tex]T=3(5)+4(-7)[/tex]
[tex]T=15-28[/tex]
[tex]T=-13[/tex]
Therefore, the value of T is -13 when x=5 and y=-7.
mrs. rodrigues wants to compare the spread of the test scores of her two biology classes. which statistic should she use? (multiple choice)
a.) mean
b.) standard deviation
c.) median
d.) mode

Mrs. Rodrigues should use Standard deviation.
The correct option is b.
What is a standard deviation?The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.
Given:
Mrs. Rodrigues wants to compare the spread of the test scores of her two biology classes.
From the given choices:
The measures of spread include:
Range, quartiles, interquartile range, variance and standard deviation.
Standard deviation is the appropriate choice.

The name of the shape in the figure is a hexagon.
What are polygons?A polygon is often a plane figure in geometry that is enclosed by a closed chain made up of a finite number of straight-line segments that end in a loop. The spots where two of these segments meet are referred to as the polygon's vertices (plural: vertices) or corners. These segments are known as its edges or sides.
Given a shape,
the shape is a polygon,
to name a polygon first count the number of sides of the figure,
as we count there are 6 sides for the shape,
There are some specific names for the shapes according to their number of sides, like

A paperweight in the shape of a rectangular prism is shown: A right rectangular prism is shown with length 10 cm, width 4 cm, and height 4 cm. If a cross section of the paperweight is cut diagonal to the base, which shape describes the cross section?
Answer:
Square
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE OF THE QUESTION
✓We were given the dimension of the rectangular prism as 10cm × 4cm × 4cm,
✓The cross section of the paperweight can be cut into half to it's base. Then the new dimension will be 4cm × 4cm which is a quadrilateral.
✓ Then width= 4cm, and height=4 cm are of the same values, hence the shape it forms is a SQUARE. and also the their angles is 90° each.

Answer:
Look below!
Step-by-step explanation:
Angle A = 180-47 = 133
Angle B = 180-32-Angle A = 180-32-47 = 101
Angle D = 90-32 = 58
Angle C = 180-47-58 = 75
Hope I helped!
Answer:
A=133 ,B=15, C=75 D= 58
Step-by-step explanation:
Angle 32, d, and right angle add up to 180. So 180=32+90+x. Then x = 58 (D). The all 3 angles in the triangle add up too 180 so 180=47+58+x. x=75 (C). The 47 and a equal to 180 degrees. 180-47=133. The 133+32+x=180. x=15 (B).
