Ben made a model (shown below) of the square pyramid he plans to build when he grows up. Find the surface area of the model.
Answer:
The answer is "[tex]240 \ m^2[/tex]"
Step-by-step explanation:
please find the given diagram image file in the attachment.
In this question, the surface area model includes two things that are square pyramid is equal to the area of the square base and the area of the flour lateral triangle:
[tex]SA= 10\times 10 +4 (\frac{1}{2}\times (10) \times (7))\\\\[/tex]
[tex]= 100 +4 (\frac{1}{2} \times 70)\\\\= 100 +4 (35)\\\\= 100 +140\\\\=240 \m^2\\\\[/tex]
The surface area of the model is [tex]240 \ m^2[/tex].
Which statements are true regarding the 270° rotation
shown? Check all that apply.
O The sides that were parallel in the pre-image are
parallel in the image.
The angle measures of ABCD are equal to the
corresponding angle measures of A'B'C'D'.
Side AB is longer than side A'B'.
The segments connecting the center rotation to
the corresponding vertices create a 270° angle.
The image has no perpendicular sides.
Answer:
1,2, and 4 are the correct answers
Step-by-step explanation:
Answer:
1. The sides that were parallel in the pre-image are parallel in the image.
2. The angle measures of ABCD are equal to the corresponding angle measures of A’B’C’D’.

Nine-hundred seven tickets were sold for a concert. Seven hundred eighty-nine people attended the concert
Part A: Write an equation for p, the number of people that bought tickets but did not attend.
Part B: How many people bought tickets but did not attend?
Answer:
A: 907-789=p
B: 118 bought tickets but didn't go.
Step-by-step explanation:
907 is the people that bought the tickets, you subtract the people that did go which is 789 which would give you the people that didn't go but still bought tickets.
that is

Answer:
a = 15, b = -14
Step-by-step explanation:
From the question,
a/5 - b/2 = 10
Multiply all through by 10
(a/5)10 - (b/2)10 = 10×10
2a - 5b = 100...................... Equation 1
a - b = 29 ........................ Equation 2
Solving equation(1 ) and equation (2) simultaneously
using elimination method,
multiply equation (2) by 2.
2a - 2b = 58.................... Equation 3
Substract equation 3 from equation 1
2a - 2a -5b-(-2b) = 100-58
0 - 5b+2b = 42
-3b = 42
b = 42/-3
b = -14.
Substitute the value of b into equation 2
a - (-14) = 29
a +14 = 29
collect like terms
a = 29-14
a = 15.
Hence, a = 15, b =-14
Mathematics Question!
Mika estimated the sum of 189.27, 15.8, and 11.2 by rounding each number to the nearest whole.
What was Mika’s estimate and what is the actual sum of the numbers?
Enter your answers in the boxes
Mika estimated the sum to be blank. The actual sum is blank
PLEASE DON’T ANSWER IF YOU DON’T NO THE ANSWER!
Answer:
Mika's estimated the sum to be 216. The actual sum is 216.27
Step-by-step explanation:
Mika:
189.27 = 189
15.8 = 16
11.2 = 11
189 + 16 + 11 = 216
Actual:
189.27 + 15.8 + 11.2 = 216.27

When there is no width, the area is 0\text{ m}^20 m
2
0, start text, space, m, end text, squared.
Answer:
When there is no width, the area is 0m²
Step-by-step explanation:
Expressing the area of a rectangle as a function of its width:
Area of a rectangle = Length * width
Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0
When x :
Area = Length * width
Area = Length * 0
Area = 0
Area = Length * 0

a. 187°
b. 88°
c. 136°
d. 160°
3. What kind of triangle has angles measuring
37°, 85°, and 58°?
Answer:
Acute triangle
Step-by-step explanation:
All of the triangles vertices are under 90 degrees.
For future reference:
Vertex (plural: vertices)= corner
Acute triangle: each vertex <90 degrees
Right triangle: One vertex = 90 degrees
Obtuse triangle: All vertices >90 degrees

Answer:
90 - 37 will give a solid 53
Step-by-step explanation:
the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)
and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37
now we add angle degrees and sum and subtract one another,
90 - 37

Answer:
4x²-5x +4 X=3
Step-by-step explanation:
The expression below has 3 terms. The first step is to plug in the 3 for all the x´s. Then find what 3 squared is. Next is to multiply the 9(3²) with the 4 to get 36. Now the expression is 36 - 5 x 3 + 4. Next is to multiply the -5 and the 3 to get 15. Now combine all like terms to get 55.

Mark is installing a mosaic tile backsplash and the shape of the tiles are shaped like regular octagons. Each tile has a length from side to side of 6 in. Once Mark gets a few pieces on the wall, he realized that there is a gap that the tiles do not cover. What size tile must he get to fill the gaps?
Answer:
square with sides of 6 in
Step-by-step explanation:
Tessellation is the arrangement of shapes in repeated patterns without gaps or overlapping.
Tessellation is usually done with regular polygons. Only three regular shapes can tessellate, these are equilateral triangle, regular square and regular hexagon. For other polygon to tessellate, more than one shape must be used. A octagon can be used to make tessellations if it is used together with a square.
Mark uses tiles with shape of octagon of sides 6 in. To fill the gaps, Mark have to uses a square with sides of 6 in
