Answer:

2/2

Step-by-step explanation:

Let the numerator and denominator be x/x

10/12÷x/x=5/6

10x/12x=5/6

x/x=5/6÷10/12

x/x=5/6×12/10

x/x=2/2

Therefore the numbers are 2/2

Answer:

2/2

Step-by-step explanation:

To reduce a fraction, you have to divide it by a fraction with the equivalency of 1, since anything else would change the value of the fraction. In this instance, you know that you have the fraction 10/12, and you need to reduce it to 5/6. To do this, you must divide 10/12 by a fraction that equals 1 to create 5/6. Breaking it down, you can know that 10 divided by 2 is 5 and that 12 divided by 2 is 6. 2/2 is equal to 1, so that is the answer.

Answer:

(i) Triangle ABC and triangle ADE are similar triangles. Hence, their ratios will be same.

Ratio of DE to BC is 4:6 => 2:3

To find area, we need to raise the ratio of length to power 2

(2/3)² = 16/x

4/9 = 16/x

x = (16*9)/4

x = 36cm²

Therefore, area of triangle ABC is 36cm²

(ii) Ratio of DE to BC is 4:8 => 1:2

(1/2)² = 25/x

1/4 = 25/x

x = 25*4

x = 100cm²

Therefore, area of triangle ABC is 100cm²

Answer:

The cutoff value for the top 5% of all IQs is 131.255.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 100, \sigma = 19[/tex]

What is the cutoff value for the top 5% of all IQs

This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.645 = \frac{X - 100}{19}[/tex]

[tex]X - 100 = 19*1.645[/tex]

[tex]X = 131.255[/tex]

The cutoff value for the top 5% of all IQs is 131.255.

Answer:

C.

Step-by-step explanation:

interior angles for ABCD is 360° and for ABO(triangle above) is 180°

from triangle,

you will get angle for OBA which is 180° - 38° - 90° = 52°

from angle B, we know that, straight line is 180°.

so,

180° = 52° +y- 12°

y = 140°

so, we can calculate x.

360° = 90° + 90° + 128° + x

x = 52°

Answer:

$9,853

Step-by-step explanation:

18% of $8,350 is $1,503, so if the price increased by 18%, we must add $8,350 and $1,503, which would equal $9,853.

Answer:

There are 220 different ways to arrange the acts.

Step-by-step explanation:

The order in which the acts are arranged is not important, so we use the combinations formula to solve this question.

Combinations Formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

How many different ways can the program manager arrange 3 different acts from the original 12

Three acts from a set of 12. So

[tex]C_{12,3} = \frac{12!}{3!(12-9)!} = 220[/tex]

There are 220 different ways to arrange the acts.

Answer:  1.75 amps

Step-by-step explanation:

V (voltage) = I (current) · R (resistance)

              V =    3.5 (110)

                 =   385

When Resistance is doubled, the current is cut in half.

             V = I R

         385 = I (2 · 110)

         [tex]\dfrac{385}{220}=\text{I}[/tex]

         1.75 = I

area of a triangular pyramid = base area + 3(triangular sides area)

                                              = 1/2 (5) 4.3  +  3 (1/2 x 5 x 8)

                                              = 10.75 + 3(20)
