A trapezoid is a parallelogram true a false
pls explain why
Answer:
True
Explanation:
Niko and Carlos are studying parallelograms and trapezoids. They agree that a parallelogram is a quadrilateral with two pairs of parallel sides. ... A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides. So a parallelogram is also a trapezoid.
Answer:
Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. so no
Step-by-step explanation:
Find the volume of the square pyramid shown. Round to the nearest cubic foot.
Answer:
3840 ft³
Step-by-step explanation:
Volume of a pyramid = 1/3( base area x height)
Base area = area of a square
area of square = length²
= 24² = 576
volume = 1/3(576 x 20) = increases as the price falls
Write the point slope form of an equation of the line through the points
Answer:
the answer is D
how to try the values of the x and y
(x,y)
Equation of a line: [tex]y = mx + c[/tex], where m is the slope and c is the y-intercept. To calculate the slope, we do so using the formula: [tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
Now plugging in our values, [tex]m = \frac{4 - (-3)}{-7 - (-2)} = \frac{4 + 3}{-7 + 2} = \frac{7}{-5} = \frac{-7}{5}[/tex]
So our slope m, is = -7/5
We can now input the value of the slope. But in this question, we cannot use the above equation of a line since we are asked to use a point-slope equation expression, so the equation is [tex]y - y1 = m(x - x1)[/tex]
Now we plug in our values,
[tex]y - (-3) = \frac{-7}{5}(x - (-2))\\y + 3 = \frac{-7}{5}(x + 2)[/tex]
So the answer should be option D.
10. Kate and Sophia are selling raffle tickets for a fundraiser.
Kate has sold 4 less than twice as many as Sophia.
If the two girls have sold a total of 38 tickets,
how many has each girl sold? equation and answer
Answer:
Sophie sold 14
Kate sold 24
Step-by-step explanation:
Kate has sold 4 less than twice as many as Sophia.
2s - 4
---------------------
sold a total of 38 tickets
Sophie + Kate = 38
s + (2s - 4) = 38
Combine like terms
3s - 4 = 38
Add 4 to both sides
3s = 42
Divide both sides by 3
s = 14
2s - 4 = 2*14 - 4 = 24

Which name best describes the polygon with vertices (0, 0), (4, 8), (12, 8), and (16, 0)? A) Triangle C) Trapezoid B) Square D) Pentagon
Answer:
C) Trapezoid
Step-by-step explanation:
Given
[tex]A = (0,0)[/tex]
[tex]B = (4,8)[/tex]
[tex]C = (12,8)[/tex]
[tex]D=(16,0)[/tex]
Required
The possible shape
The above are 4 vertices.
Hence, the shape cannot be
(a) Triangle ---- it has 3 vertices
(b) Pentagon ---- it has 5 vertices
Calculate distance AB using distance formula
[tex]AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
Where:
[tex]A = (0,0)[/tex]
[tex]B = (4,8)[/tex]
[tex]AB = \sqrt{(0 - 4)^2 + (0 - 8)^2[/tex]
[tex]AB = \sqrt{( - 4)^2 + ( - 8)^2[/tex]
[tex]AB = \sqrt{16+64[/tex]
[tex]AB = \sqrt{80[/tex]
[tex]AB = 8.94[/tex]
Calculate distance BC using distance formula
[tex]BC = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
Where:
[tex]B = (4,8)[/tex]
[tex]C = (12,8)[/tex]
[tex]BC = \sqrt{(4 - 12)^2 + (8 - 8)^2[/tex]
[tex]BC = \sqrt{(-8)^2 + (0)^2[/tex]
[tex]BC = \sqrt{64 +0[/tex]
[tex]BC = \sqrt{64[/tex]
[tex]BC = 8[/tex]
Since
[tex]AB \ne BC[/tex]
Then, the polygon is not a square

9. If each of the following pairs represents a pair of equivalent rational
numbers, find the values of x.
(i) 3/4 and 7/x
(ii) -5/6 and x/7
Answer:
-35/6
Step-by-step explanation:
We need to find the value of x , And the given pair of Rational numbers are equal.
Question (I) :-
→ 3/4 = 7/x
→ 7/x = 3/4
→ 1/x = 3/4 × 1/7
→ 1/x = 3/28
→ x = 28/3
Question (ii) :-
→ x/7 = -5/6
→ x = -5/6 × 7
→ x = -35/6
• Hence the value of x is -35/6 .Homework problem #7: 24567389+35432611=what there is soo much regrouping, could someone show me how to do it?

Answer:
(-8, 3)
Step-by-step explanation:
Answer: ( -8,3)
Step-by-step explanation:
It's not rocket science.
An ordered pair is a composition of the x coordinate (abscissa) and the y-coordinate (ordinate).
To find the ordered pair you need to be able to identify the y and x axis.
y axis is vertical
x axis is horizontal
You want to start on the x axis and find where you think the dot is stopping at...which is -8 in the problem... once you do that move on up to the dot and move your finger to the left to see where that dot is leading you to, which is 3.
And there you have it. I hope this helps. I tried my best to explain.

When multiplying fractions do you multiple it like this: 5/6 × 7/8 35/48 and if you are multiplying fractions with the same denominator do you multiply like this: 5/8 × 6/8= 30/8 or do I solve it like this: 9/10×3/10= 27/100? I am very confused please help.
Step-by-step explanation:
5/8 × 6/8= 30/8 => this is the wrong one
it should be 5/8 × 6/8= 30/64.
9/10×3/10= 27/100 => this is the true one

A cone has a slant height of 8 cm and a radius of 2 cm. Estimate the surface area using π =3, and then calculate a more accurate surface area using π =3.14.
9514 1404 393
Answer:
initial estimate: 60 cm²better estimate: 62.8 cm²Step-by-step explanation:
The total surface area of a cone with radius r and slant height s is ...
A = πr² +πrs = πr(r +s)
For the given dimensions and π≈3, the area is approximately ...
3(2 cm)(2 cm +8 cm) = 60 cm²
For π≈3.14, the area is approximately ...
(20cm²)(3.14) = 62.8 cm²
