Find the circumference of the circle with the given radius or diameter. (Use 3.14 for it.)
diameter = 25 ft
a 39.25 ft
b. 78.5 ft
C. 490.63 ft
d. 1,962.5 ft
Answer:
B. 78.5 feet
Step-by-step explanation:
The circumference of a circle can be found using the following formula.
c=πd
We know that the diameter is 25 feet. We also know we are using 3.14 for pi.
d=25
π=3.14
Substitute these values into the formula.
c=3.14*25
Multiply the two numbers together
c=78.5
Add appropriate units. Circumference uses the same units as the diameter. The diameter is 25 feet, so the units are feet.
c=78.5 feet
The circumference of the circle is 78.5 feet, and the correct answer is B
The right answer is 78.5ft

Amanda used 24 grams of paint to paint a wooden cube. When it dried, she cut the cube into 8 equal cubes. How many more grams of paint does Amanda need to paint the unpainted surfaces of the 8 cubes?
Answer:
Amanda needs 72 grams of paintStep-by-step explanation:
Notice that she already painted one face of each cube, that is, 8 faces in total, and she used 24 grams for that.
Now, there remain 3 faces per cube to be painted, which means there are 24 faces.
Then, we use the rule of three, if she used 24 grams of paint for 8 faces, how much grams of paint she would need to paint 24 faces?
[tex]24 \times \frac{24}{8}= 72 \ grams[/tex]
Therefore, Amanda needs 72 grams of paint for the unpainted surfaces.
write the following algebraically using x as your unknown “i think of a number, multiply it by 3, add 4 and square the result”
Answer:
(3x +4)²
Step-by-step explanation:
I think of a number x, then i multiply it by 3, add 4 and square the result.
Representing this mathematically,
x * 3= 3x
Then add 4 which will be 3x + 4
Squaring the result would be (3x +4)².
So, if we give our unknown which is x the value of say, 3.
Substituting the value of x into that equation would be easy.
(3 (3) +4)²
= (9 + 4)²
= (11)²
=132.

Joanne wants to buy a dishwasher. The dishwasher costs £372. Joanne will pay a deposit of £36. She will then pay the rest of the cost in 4 equal monthly payments. How much is each monthly payment?
Answer:
£84
Step-by-step explanation:
The total cost of the dishwasher is: £372
The deposit she makes is: £36
Thus, she still has to pay the following amount:
£372 - £36 = £336
And this amount will be divided into 4 equal monthly payments. So, we must divide the amount that she still has to pay by 4.
Each one of this monthly payments will have a value of:
£336 ÷ 4 = £84
the answer is that each monthly payment will be of £84
When Cara drives to work, it takes her 30 minutes to drive 15 miles. On her days off, she likes to drive to her favorite donut shop. It takes Cara 6 minutes to drive to The Dreamy Donut Shop at the same rate. How many miles away is The Dreamy Donut Shop?
Answer:
3 miles
Step-by-step explanation:
First, we find the rate at which she drives, that is her speed.
Speed is given as:
speed = distance / time
When Cara drives to work, it takes her 30 minutes to drive 15 miles. Her speed is:
s = 15 / 30 = 0.5 miles per minute.
She drives at the same rate to The Dreamy Donut Shop and it takes her 6 minutes.
From the formula of speed, distance is given as:
distance = speed * time
Therefore, the distance of The Dreamy Donut Shop is:
distance = 0.5 * 6 = 3 miles
The Dreamy Donut Shop is 3 miles away.
Answer:
The answer is 3 miles

find the equation of the sides of an isosceles right angled triangle whose vertex is (-2,3) and the base is on the line x=0
Answer:
[tex]\large \boxed{y = x + 5; y = -x + 1}[/tex]
Step-by-step explanation:
This is an isosceles right triangle, so triangles ABD and CBD are congruent.
∠ ABD = ∠CBD = 45°
The slope of BC = tan(45°) = 1, and
The slope of BA = tan(-45°) = -1.
1. Equation of BC
The point-slope formula for a straight line is
y - y₁ = m(x - x₁)
x₁ = -2; y₁ = 3; m = 1
Substitute the values
[tex]\begin{array}{rcl}y - 3 & = & 1(x - (-2))\\y - 3 & = & x + 2\\y & = & x + 5\\\end{array}\\\text{The equation for the line is $\large \boxed{\mathbf{y = x + 5}}$}[/tex]
2. Equation of BA
x₁ = -2; y₁ = 3; m = -1
Substitute the values
[tex]\begin{array}{rcl}y - 3 & = & -1(x - (-2))\\y - 3 & = & -1(x + 2)\\y - 3 & = & -x - 2\\y & = & -x +1\\\end{array}\\\text{The equation for BA is $\large \boxed{\mathbf{y = -x + 1}}$}[/tex]
An isosceles right triangle has two equal length legs and the hypotenuse side as its base
The equation of the sides of the isosceles right triangle are;
x = 0 (equation of the base)
y = 1 - x
y = x + 5
The reason for arriving at the above equations are as follows:
The given parameters of the isosceles right triangle are:
The coordinate of the vertex of the triangle = (-2, 3)
The base of the triangle, x = 0
The required parameter:
The equation of the sides of the isosceles triangle
Strategy:
Define the terms and relate the given information with the given term definitions
Solution:
The base of an isosceles triangle is the side that form the equal base angles with the two equal sides of the triangle
In an isosceles right triangle, the two equal sides of the right triangle are the legs of the right triangle, and therefore, the base of the triangle is the hypotenuse side
The base angles of an isosceles right triangle, [tex]\theta _b[/tex] = 45°
The altitude of the triangle, y = (0 - (-2) = 2
The altitude is a perpendicular bisector of the base, therefore;
[tex]tan(\theta _b) = \dfrac{Altitude}{\dfrac{1}{2} \times Base \ length }[/tex]
Therefore;
[tex]Base \ length = \dfrac{Altitude}{\dfrac{1}{2} \times tan(\theta _b)}[/tex]
We get:
[tex]\mathbf{Base \ length} = \dfrac{2}{\dfrac{1}{2} \times tan(45^{\circ})} \mathbf{= 4~}[/tex]
The coordinate of the midpoint of the base is the horizontal line from the vertex to the base, and therefore, the coordinate of the midpoint of the base is x = 0, and y = 3 = (0, 3)
The base is 4 units long and half the base length = 4/2 = 2 units
The coordinates of vertex at the base is given by adding or subtracting 2 from the y-coordinates of midpoint of the base as follows;
Vertex coordinates at the base = (0, 3 + 2) = (0, 5), and (0, 3 - 2) = (0, 1)
The slope, m₁, of the side, s₁, with endpoints (-2, 3), and (0, 1), is found as follows;
m₁ = (1 - 3)/(0 - (-2)) = -1
Therefore, the equation of the side s₁ is (y - 1) = -1·(x - 0), which gives;
y = -x + 1
The slope, m₂, of the side, s₂, with endpoints (-2, 3), and (0, 5), is found as follows;
m₂ = (5 - 3)/(0 - (-2)) = 1
Therefore, the equation of the other side s₂ is (y - 5) = 1·(x - 0), which gives;
y = x + 5
The equation of the sides are; x = 0 (given), y = 1 - x, and y = x + 5
