what is the vertical distance from the floor to the third step?(brainliest)

Answer:

x=2.5

Step-by-step explanation:

bring all terms to one side

[tex]4x^{2} -20x+25=0[/tex]

factor it

[tex](2x-5)^{2}=0[/tex]

2x-5=0

2x=5

x=2.5

Answer:

20/33

Step-by-step explanation:

4*2-13x=7x-25

8-13x=7x-25

(subtract 7 x's)

8-20x= -25

(subtract 8)

-20x= -33

Answer:

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

Suppose we have two events, A and B, that are independent. The probability of both happening is given by:

[tex]P(A \cap B) = P(A) \times P(B)[/tex]

In this question:

Event A: Selecting a prime number.

Event B: Selecting a number less than or equal to 3

Probability of selecting a prime number:

Between 1 and 10, we have 4 prime numbers(2,3, 5 and 7), out of 10. So

[tex]P(A) = \frac{4}{10}[/tex]

Probability of selecting a number less than or equal to 3:

Three numbers(1,2,3) out of 10. So

[tex]P(B) = \frac{3}{10}[/tex]

Probability of both:

[tex]P(A \cap B) = P(A) \times P(B) = \frac{4}{10} \times \frac{3}{10} = \frac{12}{100} = 0.12[/tex]

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Answer:

(2,4)

Step-by-step explanation:

Replace all occurrences of  y  with  3 x − 2  in each equation.

3x - 4 = x

y= 3x -2

Solve for  x  in the first equation.

x = 2

y = 3x - 2

Replace all occurrences of  x  with  2  in the equation.

y = 4

x= 2

The solution to the system is the complete set of ordered pairs that are valid solutions.

Answer:

7.2+x=15

x=15-7.2

x=7.8

Answer:

15:2

Step-by-step explanation:

If you take 45 / 6 you will end up with 7.5

You can't have a ratio with a fraction. So to get a whole number you multiply 7.5 by 2 to get a full number. Therefore 15:2

Answer:

  D.  Volcanic Gray

Step-by-step explanation:

The ratio of paint used is ...

   black : white = (4 gal) : (1/2 gal) = 8 : 1  . . . . . .  multiply given numbers by 2

This matches the ratio in the table for Volcanic Gray.

Answer:

Side XY is 6 units

Step-by-step explanation:

The order of ∆ QRS will be the same as the order of ∆ XYZ and the corresponding order between the 2 are congruent.

Angle Q is congruent to angle X because they are listed first. Angle R is congruent to angle Y because they are listed second. Angle S is congruent to angle Z because they are listed third.

We can see that side QR is 6 units. The corresponding side on triangle XYZ is side XY.

Answer:

(-0.5,7.66)

Step-by-step explanation:

2x+6y=21

-2x+3y=24

so 3y=24+2x

reduce

y=(24+2x)/3

substitute for y

2x+6(24+2x/3)=21

2x+(72+12x)/3=21

2x+24+4x=21

6x=-3

x=-0.5

y=(24+-1)/3=7.66

4,000 CM^2

first you multiply 8 by 5 to find out the square meters then you Multiply 100 because that's how many centimeters are in a meter and that equals 4,000.

Answer:

y is greater than 10

Step-by-step explanation:

(10, undefined)

Answer:

14

Step-by-step explanation:

It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5​'.

So we'd put 15 in y's place. It'll look like this (15 - 9).

Then we'd put 5 in x's place. It'll look like this (3 + 5).

You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!

Answer:

D ...

Step-by-step explanation:

Use the Pythagorean Theorem to figure out which triangle is NOT a right triangle. Square each leg and add them together. Then, square the hypotenuse (longest side). If the sums are equal, then the triangle IS a right triangle.

Pythagorean Theorem:

a(a) + b(b) = c(c) ; a squared plus b squared equals c squared

6(6) + 24(24) =? 26(26) ; leg a =6, leg b=24, hypotenuse=26

36 + 576 =? 676 ; simplify

612 =? 676 ; is 612 equal to 676?

Answer:

159.82

Step-by-step explanation:

262          100              let unknown be "x"

x                61

262 x 61 = 100x

15982= 100x

15982/100 = x

x= 159.82

Answer:

29.9 °F

Step-by-step explanation:

The formular for mean is given as;

Mean = Sum of Terms / Number of terms

Number of terms = 6

Sum of terms = 35.5  + 30.8  + 27.3  + 32.1  + 23.8  + 29.9 = 179.4

Mean = 179.4 / 6 = 29.9
