The circumference of a circle is 56.52 inches. What is the diameter of the circle?
A. 4.5 in.
B. 9 in.
C. 18 in.
D. 36 in.
Answer:
Circumference of a circle = πd
d=diameter
56.52=3.142d
d=17.98 inches d=18 inches
Answer:
18 in.
Step-by-step explanation:
If you do the math, you'd actually get 17.99 inches lol. Just round your answer to 18 since it's THAT close to 18.
Pythagorean theorem!! If you have a leg that is 10in long and the hypotenuse is 26in long, what is the length of the other leg?
Answer:
a = 24 inches
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 10^2 = 26^2
a^2 + 100 = 676 ////// -100 both sides
a^2 = 576
a = 24 /////UNITS!
a = 24 in.
How many vertices does a closed cone have?
What is the solution of the system of equations shown below? y = 4x + 4 y
= x^2 - 5x + 18 *
Answer:
(7, 32) and (2, 12)
Step-by-step explanation:
y = 4x + 4
y = x² - 5x + 18
4x + 4 = x² - 5x + 18
x² - 9x + 14 = 0
14 = (-7)(-2)
-9 = -7 + (-2)
(x - 7)(x - 2)=0
x= 7, x = 2
For x = 7
y = 4x + 4 = 4*7 + 4 = 32
(7, 32)
For x = 2
y = 4x + 4 = 4*2 + 4 = 12
(2, 12)
Check:
y = x² - 5x + 18
(7, 32)
32 = 7² - 5*7 + 18
32= 32 true
(2, 12)
12 = 2² - 5*2 + 18
12 = 12 true
Answer:
(7, 32) and (2, 12)

Hi! I need the answer for this question: solve until you get the minimum expression: 2x . (x+y) + 1/5 x.x + 1/2 y . (x + 3)
Answer:
11/5 x^2 + 5/2 xy + 3/2 y.
Step-by-step explanation:
2x . (x+y) + 1/5 x.x + 1/2 y . (x + 3)
= 2x^2 + 2xy + 1/5 x^2 + 1/2xy + 3/2 y
= 11/5 x^2 + 5/2 xy + 3/2 y.

What is the area??????
Answer:
15.59
Step-by-step explanation:
The answer is 15.59 because to find the area of an equilateral triangle, you need to multiply the height by the length. In this scenario, the length is 6, and we need to find the height. Since we know that all of the sides of the equilateral triangle are 6, we can put a line dividing the equilateral triangle exactly in half as our height. This will form 2 triangles, and each of them will have a length of 3, and a slant height of 6. They would also be right triangles. Now, with this information you can do pythageroum thereom to find the height:: 3^2 + h^2 = 6^2. So, h = √27. Now, to find the area of a triangle, you must multiply the length by the height and then divide by 2. So (6 • √27)/2 is equal to 15.5884572681, which rounded is equivalent to 15.59. So the answer is 15.59.
Which of these procedures is the same as multiplying a whole number by 1,000?
A. Add 1,000 to the whole number, three times.
B. Move the decimal point three places to the left and fill in the blank places with zeros.
C.Multiply the whole number by 3, ten times.
D.Move each digit of the whole number three places to the left and fill in the blank places with zeros.
Answer:
D. Move each digit of the whole number three places to the left and fill in the blank places with zeros.
Step-by-step explanation:
Take the number 5 for example.
If you multiply this by 1,000 you get 5,000.
You may do this by moving the digit 3 places to the left which will give you
5---, then you replace the empty spaces with zeros.
There are 180 girls in a mixed school. lf the ratio of girls is to boys is 4:3 , the total number of students in the school is what?
Answer:
315
Step-by-step explanation:
No. of girls be g
No. of boys be b
g= 180
g/b = 4/3
b = 3g/4
b= 3(180/4)
b= 3*45
b= 135
.
Find b+g
= 135 + 180
= 315

If -2x+3=7 and 3x+1=5+y, what is the value of y?
Answer:
y = -10
Step-by-step explanation:
To solve this, you must find the value of x first. To do this you must move the first equation so that x is by itself.
-2x + 3 = 7
Subtract 3 from both sides:
-2x = 4
Divide both sides by -2:
x = -2
Now plug in -2 for x into the second equation, like so:
3x + 1 = 5 + y
3(-2) + 1 = 5 + y
-6 + 1 = 5 + y
Add like terms:
-5 = 5 + y
Subtract 5 from both sides:
-10 = y
The value of y for the given system of equations is -10.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
As per the given,
-2x + 3 = 7 and 3x + 1 = 5 + y
-2x = 7 - 3
x = -2
Substitute as
3(-2) + 1 = 5 + y
y = -6 + 1 - 5
y = -10
Hence "The value of y for the given system of equations is -10".

plz help with slope question
Answer:
Step-by-step explanation:
Given y=2x(Let's call this eqn1) and y=x+4(eqn2)
We can substitute eqn1 in eqn2 to get
2x=x+4
2x-x=4
x=4
Substitute the value x in eqn1
y=2x
y=2(4)
y=8
Answer:
C. (4, 8)
Step-by-step explanation:
→Plug in y = 2x into y = x + 4, like so:
y = x + 4
2x = x + 4
→Subtract x from both sides:
x = 4
→Now plug in 4 for x into one of the equations (doesn't matter which one):
y = 2x
y = 2(4)
y = 8

find the area of the shape shown below
Answer:
I think the area is 12 units.
Step-by-step explanation:
Anyone correct me if I'm wrong!
So, I started with 6 times 2 is 12 but since it's a triangle, you have to divide it by 2 . Cause if you cut a square or rectangle, it will become a triangle.
So, 6 for half of the rectangle.
Then in the middle it's a square so 2 times 2= 4.
That square is 4.
Last one would be half a square, so 2 times 2= 4. Divide it in half, you get 2.
That part is 2.
Then I think you have to add all of them, 6+4+2=12
So I think it's 12 units??
Answer:
There are 3 shapes in the figure.
1 scalene triangle
1 equilateral triangle
1 square
the formula to find the area of a triangle is 1/2 x base x height:
Area of scalene triangle: 1/2 x 6 x 2 = 6 units^2
Area of equilateral triangle: 1/2 x 2 x 2 = 2 units ^2
Area of square: (base x height)
Area of square: 2 x 2 = 4 units^2
Then add up all the areas:
6 units^2 + 2 units^2 + 4 units^2 = 12 units^2
So the area of the entire figure is 12 square units.

On a coordinate plane, a curved line with a minimum value of (negative 2.5, negative 12) and a maximum value of (0, negative 3) crosses the x-axis at (negative 4, 0) and crosses the y-axis at (0, negative 3). Which statement is true about the graphed function? F(x) 0 over the interval (–∞, –3) F(x) > 0 over the interval (–∞, –4)
Answer:
f(x) > 0 over the interval [tex](-\infty,-4)[/tex]
Step-by-step explanation:
If f(x) is a continuous function, and that all the critical points of behavior change are described by the given information, then we can say that the function crossed the x axis to reach a minimum value of -12 at the point x=-2.5, then as x increases it ascends to a maximum value of -3 for x = 0 (which is also its y-axis crossing) and therefore probably a local maximum.
Then the function was above the x axis (larger than zero) from [tex]- \infty[/tex], until it crossed the x axis (becoming then negative) at the point x = -4. So the function was positive (larger than zero) in such interval.
There is no such type of unique assertion regarding the positive or negative value of the function when one extends the interval from [tex]- \infty[/tex] to -3, since between the values -4 and -3 the function adopts negative values.

Mrs. Samuelson had $350 to spend on a field trip for herself and 18 students. Admission was $12.50 per person and lunch cost about $5.00 per person. Write an equation to describe the amount of money left after the trip.
Step-by-step explanation:
Answer is $17.5
It says Mrs. Samuelson had $350 to spend on a field trip for herself and 18 students. so there are 19 people. Multiply 12.50*19 you get 237.5.
It also says lunch cost about $5.00 per person. Multiply 5.00*19 you get 95.
Add 95 to 237.5.
You get 332.5
Subtract 350 by 332.5.
Equation: 350-(19*12.50)+(19*5.00)
Answer: $17.5

Name a three dimensional shape that cannot have a triangle as a two dimensional cross section.
Answer:
A sphere
Step-by-step explanation:
A cross section of a three dimensional figure is the surface or intersection of the three dimensional figure and a plane, it is the shape obtained by cutting straight through the three dimensional figure
The shape of an inclined cross section of a cube can be a triangle however, he shape of a horizontal and inclined cross section of a sphere is a circle.
