Answer:
The surface area of the composite solid = 480 square feet
Step-by-step explanation: Given that the rectangular prism is of length of 10 feet, width of 10 feet, and height of 6 feet.
A square pyramid with triangular sides with a height of 7 feet.
The base of the pyramid = width of the rectangular prism.
Pyramid base = 10 feet
A pyramid has 4 triangular faces
Area of a triangle = 1/2bh
Area = 1/2 × 10 ×7 = 35 square feet
Total surface area = 35 × 4 = 140
Rectangular prism has 6 faces
But we will be calculating for 5 faces
Total surface area = 2(10×6) + 2(10×6) + (10×10)
= 120 + 120 + 100
= 340
The surface area of the composite solid = pyramid surface + rectangular prism surface
= 140 + 340
= 480 square feet

Answer:
The sum of the angles in the triangle is 180°.
The three angles are adjacent and form a straight
The third angle is 45°.
There is a pair of congruent angles.
Step-by-step explanation:
The diagram is missing but we can dwell on the limited information to answer.
We know angles in a triangle add up to 180°.
Therefore when we cut all these angles and arranged them on a straight line, their sum should be 180°.
Since the three angles are on a straight line they are adjacent.
Since the diagram is missing, these are the truth statement we have for now.
Answer:
The sum of the angles in the triangle is 180°.
The three angles are adjacent and form a straight angle.
The third angle is 45°.
There is a pair of congruent angles.

Find the area(ignore the line if you want)
Given:
Image of the figure
To find:
The area of the figure.
Solution:
The image is splitted into two shapes.
One is rectangle and the other is trapezium.
Reference image for answer is attached below.
Rectangle:
Length = 10 cm
Width = 2.8 cm
Area = length × width
= 10 × 2.8
Area = 28 cm²
Trapezium:
Top base = 6 cm
Bottom base = 10 cm
Height = 7.2 - 2.8 = 4.4 cm
Area = [tex]\frac{1}{2} \times\left(b_{1}+b_{2}\right) \times h[/tex]
[tex]$=\frac{1}{2} \times(6+10) \times 4.4[/tex]
[tex]$=\frac{1}{2} \times 16 \times 4.4[/tex]
Area = 35.2 cm²
Area of the figure = 28 cm² + 35.2 cm²
= 63.2 cm²
The area of the figure is 63.2 cm².

You are preparing small and large cupcakes for the school bake sale. If you will need 1/3 a spoon of sugar for each small cupcake, and 1/2 a spoon of sugar for the large cupcake.if you need to make 30 small cupcakes and 20 large cupcakes, and you have a total of 21 spoons of sugar. Is this enough to make your cupcakes?
Answer:
yes
Step-by-step explanation:
1/3x30 is 10 which would be 10 spoons
1/2x20 is also 10 which would be another 10 spoons
10+10 equals 20
you have 21 spoons which means that you will have enough spoons of sugar to make all 50 cupcakes
Answer:
Yes as the small cupcakes would need 10 spoons (=1/3 of 30) where the large cupcakes would need 10 spoons of sugar (=1/2 of 20).
Step-by-step explanation:
30 x 1/3 = 10
30 x 1/2 = 10
10+10 =20
= 20 spoons of sugar makes 10 of each size cupcakes, so 21 spoons mentioned in the question would be enough.

The length of a rectangle is 8 cm greater than its width. Find the dimensions of the rectangle if its area is 105 square centimeters. (a) Write a polynomial equation that can be solved. (b) Solve the equation by factoring (input equation with binomials in this step). (c) State solution with units *
Answer:
105 = (w+8) *w
w = 7 cm
l = 15 cm
Step-by-step explanation:
Area of a rectangle is
A = l*w
l = w+8
105 = (w+8) *w
Distribute
105 = w^2 +8w
Subtract 105 from each side
105-105 = w^2 +8w -105
0 =w^2 +8w -105
Factor
What 2 number multiply to 105 and add to 8
15*-7 = -105
15-7 = 8
(w+15) (w-7) =0
Using the zero product property
w+15 =0 w-7 =0
w=-15 w=7
impossible
not negative
w =7
l = 15
Answer:
Width: w
Length: w + 8
w(w + 8) = 105
w² + 8w - 105 = 0
w² + 15w - 7w - 105 = 0
w(w + 15) - 7(w + 15) = 0
(w + 15)(w - 7) = 0
w = -15, 7
width = 7cm
length = 7+8 = 15cm

Nate ate x ounces of blackberries. Emily ate ⅓ more than that. Write an equation to represent how much Emily ate (y) compared to Nate (x).
Answer: y = x + 1/3
Step-by-step explanation:
Hi, to answer this question we have to write equations with the information given:
The amount of blackberries that each one ate:
Nate (x)= x ounces
Emily ate ⅓ more than that. So, we have to sum the amount eaten by Nate(x) and 1/3.
Mathematically speaking:
Emily (y) = Nate + 1/3
y = x + 1/3

Find the similarity ratio and the ratio of perimeters for two regular octagons with areas of 18 in2 and50 in2
Answer:
3:5 (or 3/5)
Step-by-step explanation:
The ratio of area is equal to (ratio of perimeters)^2
That means...
(18:50) = (a:b)^2
This simplifies to:
(9:25) = (a:b)^2
Which means...
3:5 = a:b

a) work out the probability that both Jim and Sue will pass the driving test.
b) work out the probability that only one of them will pass the driving test.
please help
Answer:
the above images shows the answer to the question
The probability that both Jim and Sue will pass the driving test is 0.42. The probability that only one of them (either Jim or Sue) will pass the driving test is 0.46.
Explanation:This question falls under probability in Mathematics. To solve for these probabilities, we multiply the individual probabilities together.
a) The probability that both Jim and Sue will pass the driving test is found by multiplying the two probabilities together: 0.7 (Jim's probability) * 0.6 (Sue's probability) = 0.42. So, the probability that both will pass is 0.42.
b) The probability that only one of them will pass the driving test is found by adding the probability of the two independent events: Jim passes and Sue fails, or Sue passes and Jim fails. Jim passing and Sue failing would be 0.7 * (1 - 0.6) = 0.28. Sue passing and Jim failing would be 0.6 * (1 - 0.7) = 0.18. Adding these together, the probability that only one of them will pass is 0.28 + 0.18 = 0.46.

The two isosceles triangles are similar.
Answer:79
Step-by-step explanation:
Since a triangle has a total of 180 degrees in the interior, you can subtract 22 from 180 to get 158.Because the triangle is isosceles, the 2 remaining angles have the same measure. All you need to do now is to divide 158 by 2.
You get 59.

A restaurant offers 10 appetizers and 12 main courses. In how many ways can a person order a two-course meal? Use the Fundamental Counting Principle with two groups of items.
Answer:
80 ways
Step-by-step explanation:
The first thing is to apply the Fundamental Counting Principle with two groups of items, in this case the multiplication rule is used.
In this case, what we should do is that, for every 1 main course there are 8 appetizers, but there are 10 main courses therefore:
8 * 10 = 80
There are 80 ways to combine appetizers and the main course
Final answer:
A person can order from a restaurant 120 different two-course meals using the Fundamental Counting Principle, as there are 10 appetizers and 12 main courses to choose from.
Explanation:
The question is asking how many different two-course meals can be ordered if a restaurant offers 10 appetizers and 12 main courses. According to the Fundamental Counting Principle, if there are separate events and the first event can occur in 'm' ways and the second in 'n' ways, then the events together can occur in a total of m x n ways.
Using this principle:
Number of ways to select an appetizer = 10
Number of ways to select a main course = 12
Therefore, the total number of two-course meal combinations = 10 appetizers x 12 main courses = 120 combinations
So, a person can order 120 different two-course meals from this restaurant.

Find the volume of a right circular cone that has a height of 15.8 in and a base with a
diameter of 12.7 in. Round your answer to the nearest tenth of a cubic inch.
The right circular cone will have a volume of 667.4 cubic inches.
What is volume?A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere. Volume of a solid is measured in cubic units.
As per the given data:
height of the cone ([tex]h[/tex]) = 15.8 inch
diameter of the base ([tex]d[/tex]) = 12.7 inch
volume of a right circular cone = [tex]\frac13\pi r^2h[/tex]
Where radius ([tex]r[/tex]) = [tex]\frac{d}{2}[/tex] = [tex]\frac{12.7}{2}[/tex] = [tex]6.35[/tex]
volume = [tex]\frac13\times\pi\times (6.35)^2\times15.8[/tex]
= [tex]\frac13\times\frac{22}{7}\times (6.35)^2\times15.8[/tex]
= 667.4 cubic inches
The volume of the right circular cone will be 667.4 cubic inches.
