The surface area of the square pyramid is, A. 80 in².
What is a pyramid?A three-dimensional figure is a pyramid. Its base is a flat polygon. The remaining faces are all triangles and are referred to as lateral faces.
The number of sides on its base is equal to the number of lateral faces. The line segments that two faces intersect to form its edges. The intersection of three or more edges forms a vertex.
The given figure is a pyramid having a square base.
The pyramid also has four triangular faces, each having a base of 5 in and a height of 8 in.
Therefore, the surface area of the pyramid is,
= 4[(1/2)×5×8] square inches.
= 80 in².

What would be the first five terms of sequence whose first term is 1 and has a common ratio of 1/3?
Answers
Answer:
Step-by-step explanation:
This is a geometric sequence; we know that because of the words "common ratio." The general formula for a geometric sequence is
a(n) = a(1)*r^(n - 1), where r is the common ratio.
Here, a(1) = 1, r = 1/3, and so
a(1) = 1 (given)
a(2) = 1/3 (this is a(1) multiplied by 1/3)
a(3) = 1/9 (this is a(2) multiplied by 1/3)
a(4) = 1/27
a(5) = 1/81

Given that triangle ABC has angle ABC = 90 degrees, AB = 6 cm and BC = 9 cm. Calculate the length of AC in cm to 1 decimal place
Answers
Answer:
AC = 6.7
Step-by-step explanation:
If this is a 90 degree triangle which I am assuming it is you would the Pythagorean theorem c^2 = a^2 + b^2 since bc seems long I am using that as the hypotenuse.
9^2 = 6^2 + b^2
81 = 36 + b^2
81-36 = b^2
45 = b^2
6.7 = b
so AC = 6.7
A savings account starts with $181.25. After 7 years of continuous compounding at an interest rate, r, the account has $1450. What is the interest rate percentage? Round the answer to the nearest hundredth.
Answers
Rate of interest by which amount $181.25 becomes $1450 in 7 years by continuous compounding will be 29.71%.
Rule for the continuous compounding: Expression for the final amount comounded continuously is given by,
Final amount = [tex]Pe^{rt}[/tex]
Here, P = Principal amount
r = Rate of interest
t = Duration of investment
Given in the question,
P = $181.25
t = 7 years
Final amount = $1450
Substitute these values in the expression,
[tex]1450=181.25e^{7r}[/tex]
[tex]e^{7r}=8[/tex]
[tex]\text{ln}(e)^{7r}=\text{ln}(8)[/tex]
[tex]7r=2.07944[/tex]
[tex]r=0.2971[/tex]
[tex]r=29.71\%[/tex]
Therefore, rate of intereset for the investment is 29.71%.

Answers
Answer:
c the ratio of shots made to shots taken if 7 out of 12 shots taken are made
E the ratio of small dogs to big dogs if there are 7 small dogs and 12 big dogs
Step-by-step explanation:
Ratio of a to b:
The ratio of a to b is given by a divided by b.
A the ratio of shells to rocks if there are 7 rocks and 12 shells
12 shells and 7 rocks, so this ratio is 12 to 7.
B the ratio of shoes to dresses if there are 7 dresses and 12 shoes
12 shoes and 7 dresses, so this ratio is 12 to 7.
c the ratio of shots made to shots taken if 7 out of 12 shots taken are made
7 shots made out of 12 taken, so this ratio is 7 to 12, and c is one of the correct options.
D the ratio of sick patients to total patients if there are 7 sick patients and 12 healthy patients
7 sick patients
7 + 12 = 19 total patients
So this ratio is 7 to 19
E the ratio of small dogs to big dogs if there are 7 small dogs and 12 big dogs
7 small dogs and 12 big dogs, so this ratio is 7 to 12, and e is the other correct option.

will the contents of a cylindrical can of soup with a 1.5-inch radius and a 5-inch height fit into a pan with a 4-inch radius and 3-inch height?
Answers
Answer:
Answer: The volume of the soup can is less that that of the pan, so the soup will fit in the pan.
Step-by-step explanation:
a. V = s3
V = (7 km)3
V = 7 km × 7 km × 7 km
V = 343 km3
b. V = s3
V = (11 yd.)3
V = 11 yd. × 11 yd. × 11 yd.
V = 1,331 km cu. yd.
a. V = l × w × h
V = 6 m × 2 m × 3 m
V = 36 m3
b. V = l × w × h
V = 5 ft. × 10 ft. × 8 ft.
V = 400 cu. ft.
a. V = πr2h
V = 3.14 × (3 in.)2 × 3 in.
V = 3.14 × 9 sq. in. × 3 in.
V = 84.78 cu. in.
b. V = πr2h
V = 3.14 × (1 m)2 × 4 m
V = 3.14 × 1 m2 × 4 m
V = 12.56 m3
V = s3
V = (2 ft.)3
V = 2 ft. × 2 ft. × 2 ft.
V = 8 cu. ft.
Answer: The capacity of the ice chest is 8 cubic feet.
V = πr2h
V = 3.14 × (1 ft.)2 × 3 ft.
V = 3.14 × 1 sq. ft. × 3 ft.
V = 9.42 cu. ft.
Answer: The volume of the trash can is 9.42 cubic feet.
Closet #1
V = l × w × h
V = 4 ft. × 5 ft. × 8 ft.
V = 160 cu. ft.
Closet #2
V = l × w × h
V = 6 ft. × 3 ft. × 8 ft.
V = 144 cu. ft.
Compare the size of the closets
160 cu. ft. > 144 cu. ft.
Answer: The first closet is larger.
Both the can and the pan are cylindrical shapes. Compare the volumes of the two objects.
Volume of Can
V = πr2h
V = 3.14 × (1.5 in.)2 × 5 in.
V = 3.14 × 2.25 sq. in. × 5 in.

Volume of Pan
V = πr2h
V = 3.14 × (4 in.)2 × 3 in.
V = 3.14 × 16 sq. in.× 3 in.
V = 150.72 cu. in.
35.325 cu. in. soup can < 150.72 cu. in pan

m∠1=119∘ and m∠2=61∘.
What is m∠3?
Answers
Answer:
m∠3 = 119°
Step-by-step explanation:
All the angles must equal 360° when added together. You have two known angles that are right next to each other. If you add m∠1 and m∠2, 119 + 61, it is equal to 180°. This means that m∠3 and m∠4 must be equal to 180° as well and since there are only two lines, it is safe to assume that opposing angles are the same so m∠1 = m∠3 and m∠2 = m∠4.
