Which figures always have right angles

Answer:

One solution

Step-by-step explanation:

Basicly its just seeing if x can be anything, nothing or one thing so x · 0 = 0 has infinite answers, 4x + 6 = 11 has one solution, and 0x = 5 has no solution

Answer:

3a⁴b³

Step-by-step explanation:

subtract exponents and divide numbers

X + y = 10

Rewrite as y = 10-x

Y - x = 6

Replace y

10-x -x = 6

Simplify:

10-2x = 6

Subtract 10 from both sides:

-2x = -4

Divide both sides by -2:

X = 2

Now replace x in the first equation:

2 + y = 10

Subtract 2 from both sides:

Y = 8

The two numbers are 8 and 2

Answer:

1.02 or 51/50

Step-by-step explanation:

First we convert the fraction 6/10, as a decimal

6/10 = 0.6

Then we simply multiply

1.7 × 0.6 = 1.02

Lastly we reduce

1.02 = 1 2/100 or 51/50

Answer:

Step-by-step explanation:

Meg, add the fractions

2_1/4  +  1_1/4

or  2 + 1    +   _1/4 + _1/4

3 + _2/4

3 + _1/2

3_1/2

then what's left is  

5 - 3_1/3 =   1_1/2  

got it?

Answer:

The sample median number of occupants is 1.

Step-by-step explanation:

Median:

The measure that separates the lower half of the distribution from the upper half.

In this question:

Total of 100 cars.

64 have 1 occupant.

19 have 2 occupants

12 have 3 occupants

3 have 4 occupants

2 have 5 occupants.

Median:

In the cumulative distribution

100/2 = 50

While we count until 64, it has 1 occupant, so 50 is one occupant, which means that the sample median is 1.

The sample median number of occupants is 1.

Answer:

18 grids for each side

have a nice day ^_^

Answer:

8.0 represents how many squares there are on one side but that will measure to be 4mm on each side. We need to make it 9mm on each side by making the processor bigger and adding 5mm.

½=0.5 and thats 1 square.

Expand each side by 10 and that'll make the processor 9mm.

option B is correct because

1 hectameter is equal to 10000cm

Answer:

132,600 possibilities

Step-by-step explanation:

The first one chosen can be 1 of 52

The 2nd one chosen is 1 out 51

And the 3rd chosen is 1 out 50

So...

52 x 51 x 50 = 132,600

There are 22,100 groups of 3 customers that are possible from the given collection of 52 store customers.

It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.

We have,

The number of groups of 3 customers that can be chosen from a collection of 52 store customers can be calculated using the combination formula:

nCr = n! / r!(n - r)!

where n is the total number of customers (52) and r is the number of customers chosen (3).

Substituting the values, we get:

52C3 = 52! / 3!(52 - 3)!

52C3 = 52! / 3!49!

52C3 = (52 × 51 × 50) / (3 × 2 × 1)

52C3 = 22,100

Therefore,

There are 22,100 groups of 3 customers that are possible from the given collection of 52 store customers.

Answer:

Rounded to the nearest integer, the volume of the cylinder is 5,878 cubic inches.

Step-by-step explanation:

Given that the volume of a cylinder is calculated using the formula Phi x Radius ^ 2 x Height, and knowing that the cylinder in question has a height of 13 inches and a base diameter of 12 inches, to calculate said volume the following calculation must be done:

Phi x (12x12) x 13 = X

Phi x 144 x 13 = X

Phi x 1,872 = X

3.14 x 1,872 = X

5,878.08 = X

Thus, rounded to the nearest integer, the volume of the cylinder is 5,878 cubic inches.

The answer is 1470.3

Answer:

96 inches, and 12 feet

Step-by-step explanation:

There are 12 inches in every foot, so I multiplied 8 times 12, which is 96. Then, there are 3 feet in every yard, so I multiplied 4 times 3, which is 12. I hope this helps :)

Isolate the variable by dividing each side by the factors that don't contain variables.

Answer:

a) 3

b) 725

c) 12100

d)3900

Answer: infinitely many solutions

Step-by-step explanation:

3x + 4y = -5 ... 1

6x + 8y = -10 ... 2

Take the second equation and divide by 2

3x + 4y = -10

As you can see, the two equations are exactly the same

So they have infinite solutions

Answer:

A. is incorrect. He has to divide 76 by 19, instead of subtracting 19 to 76.

B. This equation has one solution. v=4

Step-by-step explanation:

Hi, Martin’s answer is incorrect.

A. He has to divide 76 by 19, instead of subtract 19 to 76.

The correct steps are:

19v = 76  

Since 19 is multiplying the variable, to eliminate it we have to divide by 19.

v = 76/19

v = 4

B. This equation has one solution. It’s v=4

Answer:

The factored difference is: [tex]2x(7x^3 - 10x + 5)[/tex]

Step-by-step explanation:

Difference in non factored form:

To find the difference in non-factored form, we subtract the common terms. So

[tex]24x^4 - 15x^2 + 6x - (10x^4 + 5x^2 - 4x) = 24x^4 - 10x^4 - 15x^2 - 5x^2 + 6x + 4x = 14x^4 - 20x^2 + 10x[/tex]

Greatest common factor:

Of the exponents: Between [tex]x^4, x^2[/tex] and [tex]x[/tex], it is the one with the lowest exponent, so x.

Between 14, 20 and 10:

14 - 20 - 10|2

7 - 10 - 5

So 2

The gcf is 2x, which means that the factored expression is:

[tex]2x(\frac{14x^4}{2x} - \frac{20x^2}{2x} + \frac{10x}{2x}) = 2x(7x^3 - 10x + 5)[/tex]

The factored difference is: [tex]2x(7x^3 - 10x + 5)[/tex]

Answer:

-4

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

Isolate the variable x

x - 8 = -12

To isolate the variable, add 8 to both sides (this cancels the 8 out on the left side)

x - 8 + 8 = -12 + 8

x + 0 = -4

x = -4
