What is the area of the triangle given below?
2
11
O A. 11 sq. units
B. 13 sq. units
C. 8 sq. units
O D. 22 sq. units
Answer:
Area = 11 sq. unitsStep-by-step explanation:
Base = 11 units
height = 2 units
Area = 1/2 × base × height
Area = 1/2 × 11 × 2
Area = 11 sq. units
11 square units is the area of the triangle , option A is correct.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The formula to find area of triangle is half times of base and height
Given Base is 11 units
height is 2 units
Area = 1/2 × base × height
Plug in the values of base and height
Area = 1/2 × 11 × 2
Area = 11 sq. units
Hence, 11 square units is the area of the triangle , option A is correct.

Floyd decides to invest $1,000,000 in a 20-year annuity that earns 4.6% APR compounded monthly. How much money will Floyd be paid each month from this annuity?
Answer:
$6380.38
Step-by-step explanation:
Floyd will be paid $2,504,880 each month.
What is Compound Interest?Compound interest is an interest of interest to the principal sum of a loan or deposit. The concept of compound interest is the interest adding back to the principal sum so that interest is earned during the next compounding period.
Given that Floyd invests $1,000,000 in a 20-year annuity that earns 4.6% APR compounded monthly.
A = P(1+r)ⁿ
A = 1,000,000(1+0.046/12)²⁰⁽¹²⁾
A = 2,504,880
Hence Floyd will be paid $2,504,880 each month.

Yesterday only 13 students were absent. The is 4% of the schools enrollment. What is the schools total enrollment?
Answer: 325 students
Step-by-step explanation:
13 students were absent and this is 4% of the school's total enrollment.
If 13 students represent 4% of the students, assume that x represents 100% of the students:
4% * x = 13
0.04x = 13
x = 13/0.04
x = 325 students

Three lines intersect to form the triangle shown below. What is the value of x in degrees?
Answer:
x = 40°
Step-by-step explanation:
The base angles of the triangle are 71° and 69° ( vertical angles ) , then
x = 180° - (71 + 69)° = 180° - 140° = 40°

Answer:
201.53[tex]m^{2}[/tex]
Step-by-step explanation:
That is a hexagonal pyramid, which means it consists of one hexagon and six triangles.
Let's first find the hexagonal base.
The formula to find the area of a hexagon is [tex]\frac{3\sqrt{3}}{2}a^{2}[/tex], where a is the length of one side of the hexagon. In this question, a = 6m
Solve that to find that the area of the hexagon is 93.53m^2.
Now, on to the triangles. The area of one triangle is the base times the height, then halved. We know that the base of the triangle is 6m as it shares the base with a side of the hexagon, and the question states that the height is also 6m.
6 * 6 = 36
36 / 2 = 18
Hence, the area of one triangle is 18m^2
However, there are six triangles - not just one!
6 * 18 = 108
Adding everything up:
93.53 + 108 = 201.53
The answer is 201.53m^2
Pomocy. Wskaż powierzchnię całkowita sześcianu, którego objętość jest równa 64 cm.
4. 16 om?
B. 64 cm
C. 96 cm2
D. 512 cm?
Answer:
C. 96 cm²
Step-by-step explanation:
Objętość sześcianu = 64 cm³
Krok 1
Znajdujemy długość boku sześcianu
Objętość = (długość boku) ³
64 = a³
a = pierwiastek sześcienny (64)
a = 4 cm
Krok 2
Znajdujemy obszar sześcianu
Wzór na całkowitą powierzchnię sześcianu = 6a²
a = 4 cm
Całkowita powierzchnia = 6 × 4²
= 6 × 16
= 96 cm²

A construction company spends w weeks extending an existing road. The existing road is 5 miles long. Each week the company completes 0.2 miles of the extension. Which equation models the total length (L) of the road?
A. L = 0.2w + 5
B. L = 0.2w - 5
C. w = 0.2L + 5
D. w = 0.2L - 5
Answer:
L = 0.2w + 5
Since there is already 5 miles, your adding 0.2w. Its not 0.2L because that is the total length and its the sum.
Answer:
L= 0.22+5

Answer:
785cm³
Step-by-step explanation:
3.14×5=15.7
15.7×5=78.5
78.5×10=785
785cm³
Answer:
Volume is 785 cm^3
Step-by-step explanation:
Well first you can find the area of the base which in this case is the circle.
Follow the formula to find area of a circle
a=πr^2
We know π is 3.14 so plug in the radius which is 5
3.14*5^2=a
Solve and you’d get 78.5
Now multiply the base by the height
78.5*10= 785
A farmer sells 8.7 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Answer:
2.2 kg
Step-by-step explanation:
1000g = 1kg
8700g = 8.7kg
3/4 = 75%
8700 / 100 = 87
87 * 75 = 6525
8700 - 6525 = 2175
2.175kg or if rounded 2.2kg

Given:
The right triangular prism.
Height of prism = 28 in.
Hypotenuse of base = 25 in.
leg of base = 24 in.
To find:
The lateral surface area of the prism.
Solution:
Pythagoras theorem:
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
Using Pythagoras theorem in the base triangle, we get
[tex]25^2=24^2+Base^2[/tex]
[tex]625-576=Base^2[/tex]
[tex]\sqrt{49}=Base[/tex]
[tex]7=Base[/tex]
The perimeter of the triangular base is:
[tex]P=7+25+24[/tex]
[tex]P=56[/tex]
Lateral area of a triangular prism is:
[tex]A=Ph[/tex]
Where, P is the perimeter of the triangular base and h is the height of the prism.
Putting [tex]P=56,h=28[/tex] in the above formula, we get
[tex]A=56(28)[/tex]
[tex]A=1568[/tex]
Therefore, the lateral area of the prism is 1568 in².

Answer:
$85000
Step-by-step explanation:
Answer: The answer is $85,000
Step-by-step explanation: Basically, you have to divide -3,400 on both sides. So 85,000 ÷ -3,400 = -25. Now, you have to substitute x, which is -25. -3,400 x -25 = 85,000. Hope this helps!! :)

Step-by-step explanation:
Correct me if i'm wrong but I read this as (4-1)x(4-1)x(4-1).
Ok so the first step to follow in the order of operation is to do the equations in the paranthesis. 4-1=3.
So it is like dis: 3x3x3.
First 3x3=9, then we do it again but to nine this time. 9x3=27. there u have it
also i cant change my answer or edit it so im sry if this answer is wrong and like- unchangable :/
