Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

All multiples of 10 end with 0 only. So 35 must be wrong as it ends with 5. Therefore, Greg is incorrect.

Answer:

(a) The probability of rolling a 1 on a 6-sided number cube is  

1/6

​

. This is because there is 1 outcome that results in a 1 (rolling a 1) and there are 6 total possible outcomes.

(b) The probability that you either roll a 1 or do not roll a 1 is 1. This is because there are no other possible outcomes. You either roll a 1 or you don't.

(c) The probability that you don't roll a 1 is  6/5

​

. This is because there are 5 outcomes that do not result in a 1 (rolling a 2, 3, 4, 5, or 6) and there are 6 total possible outcomes.

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Step-by-step explanation:

The volume of the cylinder is 62.83 cubic cm and the volume of. the cone is 20.94 cubic cm.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

We know that,

It should be noted the to calculate the volume of a cylinder, we can use the formula V = πr²h, where r is the radius and h is the height. In this case, the height and radius of the cylinder and cone are the same.

For the cylinder:

Volume = π(2cm)²(5cm)

V = 20π

For the cone, we can use the formula

V = (1/3)πr²h:

V = (1/3)π(2cm)²(5cm)

V = 20/3π cubic cm (exact value)

Hence, to get an approximate decimal value, we can use a calculator to evaluate:

Volume of cylinder ≈ 62.83 cubic cm

Volume of cone ≈ 20.94 cubic cm

Answer: .28, .16, 0, .34

Step-by-step explanation:

Answer: We can find the equation of a plane in point-normal form, which is given by:

Ax + By + Cz + D = 0

where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.

To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:

v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >

The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>

So the normal vector is given by:

n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k

Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:

A2 + B-3 + C*1 + D = 0

-142 + -7-3 + -11*1 + D = 0

-28 - 21 - 11 + D = 0

D = 58

So the equation of the plane is :

14x - 7y - 11z + 58 = 0

This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)

Answer:

9:14

Step-by-step explanation:

If the ratio of girls to students is 5:14, that means there are 9 boys for every 5 girls. Therefore, the ratio of boys to students is 9:14.

Answer:

9

Step-by-step explanation:

Girls = 5 out of 14

So, ratio of girls to total strength is 5:14

Boys = 14-5 = 9 boys

So, ratio of boys to total strength is 9:14

Ratio of boys is 9

Answer:

I think it's figure B

Step-by-step explanation:

Over the y axis it would be in the quadrant where figure A is then move it three units down. It could only be B. For C it is reflected over the x axis so that can't be it.

Answer:

The answer is B. You're welcome!

Part A: 15x= $810.75. Part B: x= $54.05

The total money earned from 15 tickets is $810.75.

Assume, the money earned from selling 1 ticket is $x.

Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75

Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.

Using the equation above,

15x= $810.75.

Dividing both sides by 15,

We get,

x= $54.05

Hence, $54.05 is the price of each ticket.

Answer: a. 5

Since the angle is right, we know it is equal to 90 degrees.

Using the information provided, we can set up an equation.

50 + 5x + 15 = 90

Simplifying the equation, we get:

5x + 65 = 90

Subtracting 65 from both sides, we get:

5x = 25

Dividing both sides by 5, we get:

x = 5

Answer:

The integer that describes the translation from B to B' is (-2,1)

Answer:

\(-2\)

Step-by-step explanation:

To find the rate of change of a function, we are looking for it's slope.

We can find the slope of a line by seeing it's rise over run.

Basically - how much the line's y increases divided by how much the line's x increases.

We can see that the y drops from 1 to -1 in 1 x value. This means the change in y is \(1 - (-1) = 2\), however in this case it is -2 as we are dropping.

The change in x is 1 .

This means that the slope (rate of change) is \(\frac{-2}{1} = -2\).

Answer:

1. y = 7

2.  y = 6

3.  y = 7/2

4. y = 8

Step-by-step explanation:

I searched it up and found the answer.

Let's solve each equation one by one :

➝ 7y + 7 = 56

➝ 7y = 56 - 7

➝ 7y = 49

➝ y = 49 / 7

➝ y = 7

➝ 42 - 6y = 6

➝ - 6y = 6 - 42

➝ - 6y = - 36

➝ y = -36 / - 6

➝ y = 6

➝ ( y + 1 )² = 9

➝ y + 1 = √ 9

➝ y + 1 = 3

➝ y = 3 - 1

➝ y = 2

➝ 1 + 72 / y = 10

➝ 72 / y = 10 - 1

➝ 72 / y = 9

➝ 72 = 9y

➝ 9y = 72

➝ y = 72 / 9

➝ y = 8

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅
