Answer:

Area of square=81 cm^2. ✳But area=side^2. ✳81=s^2

Answer:

Assuming the question is wanting to know the area of a square with sides of 81 inches each, the answer would be

6561 inches squared

Step-by-step explanation:

if each side of the square is 81 inches, you multiply

81 x 81 = 6561

Answer:

h≅ 8 yards

Step-by-step explanation:

Given data

Volume of cone= 301.44 cubic yards

Radius of cone= 6 yards

Required

The Height of the cone

The expression for the volume of a cone is given as

V= 1/3πr^2h

Substitute

301.44= 1/3* 3.142*6^2*h

301.44= 37.704*h

Divide both sides by 37.704

h= 301.44/37.704

h= 7.99

h≅ 8 yards

A ratio shows us the number of times a number contains another number. The correct answer is 20.

A ratio shows us the number of times a number contains another number.

Given that the table shows the ratio of the number of red beans to the total number of beans. Therefore, we can write the ratio as,

(Red Bean)/(Total Bean) = 3/5 = 12/x = 15/25 = 21/35

Further, it can be solved,

3/5 = 12/x

(5×12)/3 = x

60/3 = x

x = 20

Answer:

D - the slope will be at 25

Step-by-step explanation:

Taking the first two values

slope = (y2 - y1) / (x2 - x1) = (125 - 100) / (3 - 2) = 25 / 1 = 25

Answer:

C is the answer

Step-by-step explanation:

i randomly found out

The geometric construction in option (C) depicts a ray.

In mathematics, a ray is a segment of a line with a fixed starting point but no ending. It can go on forever in a single direction. A ray cannot be measured since it has no end point.

In the given geometric construction,

Diagram A, shows a parallelogram. Therefore, is not a ray.

In diagram B there is no starting point, it shows a line. Therefore, it is also not a ray.

In diagram C, there is a starting point and no ending point.

Depicts that this geometric construction is a ray.

Diagram D shows the line segment.

Hence, Diagram C depicts a ray.

Answer:

D. $150 in 4%, $850 in 6%

Step-by-step explanation:

1. The amount available to invest in the accounts, A = $1,000

The amount of average interest rate needed = 5.7 percent = 0.057

The interest paid by one of the accounts, account 1, I₁ = 4 percent = 0.04

The interest paid by the other account, account 2, I₂ = 6 percent = 0.06

Let 'x' represent the amount invested in account 1 that pays 4% and let 'y' represent the amount invested in account 2, that pays 6% we get;

x + y = 1,000...(1)

0.04·x + 0.06·y = 0.057 × 1,000 = 57

∴ 0.04·x + 0.06·y = 57...(2)

Making 'y' the subject of equation (1) and (2), we have;

For equation (1), y = 1,000 - x...(3)

For equation (2), y = 950 - (2/3)·x...(4)

Subtract equation (4) from equation (3) gives;

y - y = 1,000 - x - (950 - (2/3)·x)

0 = 1,000 - 950 - x + (2/3)·x

0 = 50 - (1/3)·x

(1/3)·x = 50

x = 3 × 50 = 150

x = 150

The amount invested in the 4% account, x = $150

From equation (3), we have;

y = 1,000 - x

∴ y = 1,000 - 150 = 850

y = 850

The amount invested in the 6% account, y = $850.

Therefore;

$150 should be invested in the account that pays 4% while $850 should be invested in the account that pays 6%.

Answer:

$150 in 4%, $850 in 6%

Answer:

A = 1124 cm²

V = 840 cm³

Step-by-step explanation:

Assuming the prism is a triangular prism,

Applying,

V = 1/2bhL.................. Equation 1

Where V = volume of the prism, L= lenght of the prism, b = base of the triangle, h = height of the triangle

From the question,

Given: L = 28 cm, 12 cm, h = 5 cm

Substitute these values into equation 1

V = (5×12×28)/2

V = 840 cm³

Surface area (A) = bh+(a+b+c)L

A = (5×12)+(13+13+12)28

A = 60+1064

A = 1124 cm²

Step-by-step explanation:

Answer:

0.50

Step-by-step explanation:

The question states at least 2 which means 2 or more.

The only applicable numbers to look at would be 2 and 3.

First of all we find 2 since it's missing.

Now all probability distributions must add up to 1.

As we can see there are 0.20, 0.30 and 0.40 which is equal to 0.90. Therefore 1 - 0.90 = 0.10 which would be 2.

Hence, the peobability that x is at least 2 is 0.10 + 0.40 = 0.50.

Answer:

50 % alcohol solution = 10 millimetres

30 % alcohol solution = 90 millimetres

Step-by-step explanation:

two equations can be derived from this question

x + y = 100 equation 1

0.3x + 0.5y = 100 x 0.32 = 32

0.3x + 0.5y = 32 equation 2

where :

x = 30% alcohol solution

y = 50% alcohol solution

multiply equation 1 by 0.3

0.3x + 0.3y = 30 equation 3

subtract equation 3 from 2

0.2y = 2

y = 10

substitute for y in equation 1

x + 10 = 100

x = 100 - 10

x = 90

Answer:

70

Step-by-step explanation:

your height is 14, Given

Your surface area for the top face is 14

the way to make 14 from two factors is 7 and 2

therefore your height is 5 your width is 7 and your depth is 2

Let us consider the ration of two numbers be x

The two numbers are 5x and 3x

Since two numbers differ by 18, we can write the equation

5x – 3x = 18

2x = 18

x= 9

Therefore the two numbers are

5x = 5 x 9 = 45

and

3x = 3 x 9 = 27

∴ The two numbers are 45 and 27.

Step-by-step explanation:

n(s) for 2 cubes =6×6=36

Given:

On a circle, UT and UV are two tangent

Measure of arc VT = 125 degrees.

To find:

The measure of angle TUV.

Solution:

Intersecting tangents theorem: According to this theorem, if two tangent are drawn to the circle then the measure of angle on the intersection is half of the difference of intercepted major arc and minor arc.

We know that the measure of complete arc of a circle is 360 degrees. So,

[tex]\text{Major arc}(VT)=360^\circ -\text{Minor arc}(VT)[/tex]

[tex]\text{Major arc}(VT)=360^\circ -125^\circ[/tex]

[tex]\text{Major arc}(VT)=235^\circ[/tex]

Using Intersecting tangents theorem, we get

[tex]m\angle TUV =\dfrac{1}{2}(\text{Major arc}(VT)-\text{Minor arc}(VT))[/tex]

[tex]m\angle TUV =\dfrac{1}{2}(235^\circ -125^\circ )[/tex]

[tex]m\angle TUV =\dfrac{1}{2}(110^\circ )[/tex]

[tex]m\angle TUV =55^\circ[/tex]

Therefore, the measure of angle TUV is 55 degrees.

Answer:

the answer would be A 120
