A) pyramid
Explanation:
When you take the cross-section of a pyramid parallel to the base, the cross-section will be in the shape of the base.
As you take cross-sections further up the pyramid, you will still get a cross-section that is in the shape of the base, but it will be smaller. This is because as you go further up the pyramid, the distance between vertices is shorter because it comes to a point.
Answer:
pyramidStep-by-step explanation:
A__pyramid has cross-sectional shapes, taken parallel to a base, that are similar but not congruent to one another.

The measure of angle J is 19.8°, and the correct option is D.
What is the formula of cosine?The law of cosine or cosine rule in trigonometry is a relation between the side and the angles of a triangle. Suppose a triangle with sides a, b, c and with angles cosC.
The following formula is used to find the angle j is;
[tex]\rm j^2 = h^2 + i^2 -2hicosC[/tex]
Triangle HIJ has side lengths h=12, i = 17, j = 7.
Substitute all the values in the formula;
[tex]\rm j^2 = h^2 + i^2 -2hicosJ\\\\(7)^2=(12)^2+(17)^2-2 \times 12 \times 17 cosJ\\\\49=144+289-408cosJ\\\\144+289 -49 =408cosJ\\\\384 =408cosJ\\\\cosJ=\dfrac{384}{408}\\\\cosj = 0.94\\\\J =cos^{-1}(0.94)\\\\J=19.8[/tex]
Hence, the measure of angle J is 19.8°, and the correct option is D.

An ice cream truck was parked near a beach, and some kids ran to it and formed a line. Then, more kids joined the line by filling in each empty space between the kids in the original line. This happened two more times before the ice cream truck driver finally came back from his lunch break, and there were 49 kids in line. How many kids were in the first line?
Answer:
7
Step-by-step explanation:
So, we know that this process happened 3 times in total. The original amount of kids we can call x, so the next wave filled in the gaps inbetween, so we call that amount x-1, the next wave would be (x+x-1)-1 or 2x-2, and the last would be 4x-4
adding this all up we get 8x-7=49, so 8x = 56 or x = 7

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Lucy is counting by 2s, starting with 2, which means that she is counting all even numbers between 2 and 50.
To find the number that Lucy would not count, we need to find the odd number between 2 and 50.
On simplifying the equation , we get
The odd numbers between 2 and 50 are: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, and 49.

xy = 12.
As it reaches the point (4, 3), the y-coordinate is decreasing at a rate of 3 cm/s. How fast is the x-coordinate of the point changing at that instant?
first off, let's notice that "x" and "y" are encapsulating a function in terms of time or namely "t", and that dy/dt is decreasing at a rate of 3 cm/s, since the rate is decreasing, that makes the rate negative, thus is changing at -3 cm/s.
[tex]xy=12\implies \stackrel{product~rule}{\cfrac{dx}{dt}y~~ + ~~ x\cfrac{dy}{dt}}~~ = ~~0\implies \cfrac{dx}{dt}y~~ + ~~x(-3)~~ = ~~0 \\\\\\ \cfrac{dx}{dt}y=3x\implies \left. \cfrac{dx}{dt}=\cfrac{3x}{y} \right|_{(\stackrel{x}{4},\stackrel{y}{3})}\implies \cfrac{3(4)}{3}\implies 4[/tex]

What value of x makes this equation true? -24 = 6 + x
Answer:
x = -30
Step-by-step explanation:
-24 = 6 + x
we'll subtract 6 to get x alone:
-24 - 6 = x
-30 = x
____________
then to check, we plug it back in
-24 = 6 + (-30)
-24 = -24 true! so -30 is right :)
Answer:
-30
Step-by-step explanation:
You can backtrack to find x:

Circle K has an area of 80 cm^2. Circle M has a radius that is 2 times the radius of Circle K. What is the area of Circle M?
Answer:
Two shapes are similar when they have the same shape while their sizes may be the same or different
Therefore, two similar shapes are shapes that have a relationship such that the dimensions of one of the shapes can be obtained from the dimensions of the other shape by multiplying by a scale factor
All circles have the same shape and are defined by their center and radius
Given circle with center at 'x' and radius 'r' and circle with center 'y' and radius 's', then there exist a scale factor a = s/r such that we have;
r × a = s
Where a = s/r, we get;
r × s/r = s
We can therefore, obtain a circle with with the same size as the circle with center 'y' and radius 's' by multiplying the radius of the circle with center at 'x' and radius 'r' by a
Therefore the circle with center at 'x' and radius 'r' is similar to the circle with center 'y' and radius 's'Step-by-step explanation:

Find the value of x. Round your answer to the nearest tenth
Answer:
13.8
Step-by-step explanation:
Let us use tan theta to find the value of x.
tan Θ = Opposite ÷ Adjacent
Given that,
Opposite ⇒ 12
Let us solve it now.
tan Θ = Opposite ÷ Adjacent
tan 41 = 12 ÷ x
0.8692 = 12 ÷ x
x = 12 ÷ 0.8692
x = 13.80
x ≈ 13.8
5) Paul invests $3,092 in a savings account
with a fixed annual interest rate
compounded 4 times per year.
After 9
years,
the balance reaches $4,835.71.
What is the interest rate of the account?
Answer:
R = 5% per year
Step-by-step explanation:
Solving for rate r as a decimal
r = n[(A/P)^1/nt - 1]
r = 4 × [(4,835.71/3,092.00)^1/(4)(9) - 1]
r = 0.05
Then convert r to R as a percentage
R = r * 100
R = 0.05 * 100
R = 5%/year
Summary:
The interest rate required to get a total amount of $4,835.71 from compound interest on a principal of $3,092.00 compounded 4 times per year over 9 years is 5% per year.

Answer:
1st Part: Infinitely many solutions
2nd Part: Exactly one solution
3rd Part: No Solutions
Step-by-step explanation:
First Part: 4(x - 1) = 4x - 4
Distribute. 4x - 4 = 4x - 4
Because the equations are the same, any value can be substituted for x and both the equations' values would still be equivalent.
2nd Part:
x + 4 = 4(x + 1)
x + 4 = 4x + 4
Minus 4 both sides
x = 4x
Only 0 can make this equation true, meaning it only has ONE solution.
Third Part:
4x + 1 = 4(x - 1)
Distribute.
4x + 1 = 4x - 1
Subtract 4x both sides
1 = -1
Obviously, 1 and -1 are not equivalent, meaning there are no value that can be substituted for x to make this equation true.

A regular hexagon is dilated by a scale factor of 4/3 to create a new hexagon. How does the perimeter of the new hexagon compare with the original perimeter?
oPTIONS:
The perimeter of the new hexagon is 4/3 the perimeter of the original hexagon.
The perimeter of the new hexagon is 12/3 the perimeter of the original hexagon.
The perimeter of the new hexagon is 16/3 the perimeter of the original hexagon.
The perimeter of the new hexagon is 16/9 the perimeter of the original hexagon.
Answer:
When a figure is dilated by a scale factor of a/b, then the new perimeter is a/b of the original perimeter and the new area is a 2 b 2 of the original area. Therefore, if the hexagon is dilated by a scale factor of , then the new perimeter is of the original perimeter.
