1 answer:
cluponka [151]2 years ago
8 0

Answer

92%

Explanation

23 out of 25 people voted Abdul.

So that means \frac{23}{25} people voted Abdul.

When you divide 23 by 25 you get 0.92 which is 92% (multiply by 100).

You divide because a fraction means the numerator divided by the denominator.

A carpenter wants to expand a square room. The new room will have one side 4 feet longer and the adjacent side 6 feet longer tha
gogolik [260]

Answer:

  Dimensions of original room = 12 x 12 feet.

Explanation:

 Let the size of old square room be a x a.

 New dimension = ( a+4 ) x ( a + 6 )

   We have area of the new room will be 144 square feet greater than the area of the original room.

  So,     ( a+4 ) x ( a + 6 ) = a x a + 144

              a²+10a+24= a²+144

              10a = 120

                  a = 12 feet.

 Dimensions of original room = 12 x 12 feet.

Which polynomial function has a leading coefficient of 1 and roots /7 and - /3 with multiplicity 1?
VladimirAG [237]

Answer:

  • A.  f(x) = (x - √2)(x + √3)

Step-by-step explanation:

Leading coefficient is 1, multiplicity is 1, roots are √2 and -√3. It means the function is the product of two binomials.

<u>The function with the roots of a and b is:</u>

  • f(x) = (x - a)(x - b)

<u>Substitute and and b:</u>

  • f(x) = (x - √2)(x - (-√3)) ⇒
  • f(x) = (x - √2)(x + √3)

Correct choice is A

If the unknown value is x, then x = \frac{14}{4} × 6 = 21.

Explanation:

  • Since it is a double number line with a ratio, all the ratios of one number line to the other will remain equal for all the values along both the number lines. Assume the unknown value to be x.
  • The ratio of the number on the first number line to the corresponding number on the second number line is calculated to be;                                  \frac{7}{2} = \frac{14}{4} = \frac{x}{6} = \frac{28}{8} = \frac{35}{10} = 3.5. So \frac{x}{6} = 3.5, x = 3.5 × 6 = 21.
  • We can also calculate x by the following method. As ratios are equal we can directly substitute the value to another ration.                                                      So \frac{14}{4} = \frac{x}{6}, x = \frac{14}{4} × 6 = \frac{84}{4} = 21.
