Answer:

-1 17/25

Solution with Steps

−65−1225=?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(-6/5, 12/25) = 25

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(−65×55)−(1225×11)=?

Complete the multiplication and the equation becomes

−3025−1225=?

The two fractions now have like denominators so you can subtract the numerators.

Then:

−30−1225=−4225

This fraction cannot be reduced.

The fraction

−4225

is the same as

−42÷25

Convert to a mixed number using

long division for -42 ÷ 25 = -1R17, so

−4225=−11725

Therefore:

−65−1225=−11725

ira [324]

Answer:

Step-by-step explanation:

the area of the squared is 5 * 5 = 25

the area of the triangle is 1/2*base*height = 1/2*2*5= 5

the area of the circle is $\pi$ $r^{2}$ = $\pi$ $2.5^{2}$ = 19.625

now add the pieces up for the total

25+5+19.625 = 49.625 $in^{2}$

Name the relationship A.complementary B.linear pair C.vertical D.adjacent

Tom [10]

Answer:

∠a and ∠b are the adjacent angles.

Therefore, option D i.e. adjacent is the correct option.

Step-by-step explanation:

Given the angles

∠a

∠b

We know that the two angles are termed as the adjacent angles when they share the:

common vertex

common side

From the given diagram, we are given the angles ∠a and ∠b.

It is clear that angles ∠a and ∠b have a common vertex and common side.

Therefore, the relationship between the angles ∠a and ∠b is 'adjacent'.

In other words, ∠a and ∠b are the adjacent angles.

Please note that the given relation can not be a 'linear pair' because the sum of two angles is NOT a straight line or 180°.

Therefore, option D i.e. adjacent is the correct option.

0 + 895.6 = g · 568.57 + 895.6 · 1

seraphim [82]

Answer:

Steps

0+ 895.6 =gx 568.57 + 895.6 x 1

Switch sides

gx 568.57 + 895.6 x 1 =0+ 895.6

Multiply the numbers: 895.6 x 1= 895.6

568.57g + 895.6 = 0 + 895.6

Add the numbers: 0 + 895.6 = 895.6

568.57g + 895.6 = 895.6

Multiply both sides by 100

568.57g x 100 + 895.6 x 100 = 895.6 x 100

Refine

56857g + 89560 = 89560

Subtract 89560 from both sides

56857g + 89560 –89560=89560 – 89560

Simplify

56857g =0

Divide both sides by 56857

56857g/56857=0/56857

Simplify

g=0

The probability of success is 0.6 for each trial. Find the probability of each:

lapo4ka [179]

Answer:

1. 0.1367

2. 0.0709

3. 0.1766

Step-by-step explanation:

The probability of success is p=0.6, then the probability of a failure is q=1-0.6=0.4.

1. The probability that there are exactly 13 successes in 24 trials is

$C^{24}_{13}p^{13}q^{24-13}=\dfrac{24!}{13!(24-13)!}\cdot (0.6)^{13}\cdot (0.4)^{11}\approx 0.1367$

2. The probability that there are exactly 9 successes in 20 trials is

$C^{20}_{9}p^{9}q^{20-9}=\dfrac{20!}{9!(20-9)!}\cdot (0.6)^{9}\cdot (0.4)^{11}\approx 0.0709$

3. The probability that there are exactly 6 failures in 12 trials is

$C^{12}_{6}q^{6}p^{12-6}=\dfrac{12!}{6!(12-6)!}\cdot (0.4)^{6}\cdot (0.6)^{6}\approx 0.1766$
