Answer:

by straight line property

a+156=180

a= 180-156

a=24°

Answer:

a=24

expanation

360 divided by 2 is 180 and 180 minus 156 equals 24

Explanation:

Rule: if |x| > k, then x < -k or x > k

Using that rule for the given inequality means we have these steps

|x-4| > 3

x-4 < -3  or x-4 > 3

x < -3+4 or x > 3+4

x < 1  or  x > 7 ..... choice E

-------------

Here's a visual way to see why this is the case.

|x-4| represents the distance from x to 4 on the number line.

When we say |x-4| > 3, we want to know which points are more than 3 units away from 4 on the number line.

We can plot 4 on the number line, and then measure 3 units below it (to get to 1) and then 3 units above it (to get to 7). If we're in the region 1 < x < 7, then we're within 3 units of 4 on the number line. Otherwise, we're more than 3 units away from the target we're after.

Answer:

−0.2542372881

Answer:

length = 12

width = 15

Step-by-step explanation:

if you foil (x+7)(x+10) you get:

x²+17x-110 = 0

the factors are:

(x+22)(x-5) = 0

x = -22 and 5

we can dismiss the negative as irrelevant for a measure; therefore, x = 5

length = 5+7, or 12

width = 5+10, or 15

Answer:

2:17 am

Step-by-step explanation:

3 hours after 10:46 would be 1:46

1:46 plus 31 minutes is 1:77 but there are only 60 minutes in an hour so 1:77 is 17 minutes after 2:00, or 2:17 am

Answer:

c. normal probability distribution

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question:

By the Central Limit Theorem, it is a normal distribution, so option c.

Answer:

Agree

Step-by-step explanation:

If you multiply 0.2 by 3, you get 0.6

If you multiply 0.6 by 3, you get 1.8

If you multiply 1.8 by 3, you get 5.4

If you multiply 5.4 by 3, you get 16.2

If you multiply 16.2 by 3, you get 48.6

48.6 is close to being half of the island.

Answer:

[tex]sec x = - \frac{3}{2}[/tex]

Step-by-step explanation:

[tex]cos x = \frac{-2}{3}\\\\sec x = \frac{1}{cosx}\\\\Therefore, sec x = \frac{3}{-2} = \frac{-3}{2}[/tex]

Answer:

sec x = -3/2

Step-by-step explanation:

sec = 1/cos

sec x = 1 / (-2/3)

sec x = -3/2

Answer:

2/5

Step-by-step explanation:

(-2 , 2) = (x1 , x2)

(3 , 4) = (x2 , y2)

slope = y2 - y1/x2 - x1

=4 - 2/3 - (-2)

=2/3+2

=2/5

Answer:

m = -3

Step-by-step explanation:

Two poin on this line are (-2, 3) and (0, -3).  Both points are formed where grid lines meet precisely.

The change in x as we go from (-2, 3) to (0, -3) is +2 and the change in y is -6.  Thus, the slope of the line shown is m = rise/run = -6/2, or m = -3.

Answer:

C

625

Step-by-step explanation:

We must first find the length of the side

So remember that the area of a square is side squared

So to find the length of the side we square root A

Since the perimeter of a square is 4 times the side we end up with 4square root(A)

And the whole thing must equal less than 100

So its C

Answer:

0.5185 kg are needed to make 2 kg of cat food

Step-by-step explanation:

Chicken bones and chicken pieces in the ratio 20:7

This means that [tex]\frac{20}{20 + 7} = \frac{20}{27}[/tex] of the total weight is of bones and [tex]\frac{7}{27}[/tex] is of pieces.

What weight of chicken pieces is needed to make 2 kg of cat food?

7/27 of 2kg. So

(7/27)*2 = 14/27 = 0.5185 kg

0.5185 kg are needed to make 2 kg of cat food

Answer:

Angle 2 = 124 degrees

Step-by-step explanation:

Angles 1 and 2 are corresponding angles since the two lines are parallel.

We can put both numbers into an equation.

3x + 25 = 2x + 58

Subtract both sides by 2x which will give:

x + 25 = 58

Now, we can solve for x, which is:

x = 58-25 = 33

Put back x = 33 into angle 2.

Hence, angle 2 is 2*33 + 58 = 124

Answer:

m∠2 = 124 degrees

Step-by-step explanation:

By the definition of "Same Side Corresponding Angles" the 2 angles given are congruent to each other, therefore we can say;

3x + 25 = 2x + 58

x + 25 = 58

x = 58 - 25

x = 33

Now that we have x = 33, we can substitute 33 in for x, in equation given for angle 2 to find it's measure;

∠2 = 2(33) + 58

∠2 = 66 + 58

∠2 = 124

Therefore m∠2 = 124 degrees.

Answer:

The discount was A) $ 24.51 and B) 14.5% of the value.

Step-by-step explanation:

Since a department store offered a 10% discount on all humidifiers, and they also stated that the first 50 customers would receive an additional 5% discount off the sale price, if I purchase a humidifier that sells for $ 169 and I are among the first 50 customers, to determine what will my total discount be (a) in dollar amount and (b) in percent, the following calculation must be performed:

100 - 10 = 90

100 - 5 = 95

(169 x 0.9) x 0.95 = X

152.1 x 0.95 = X

144.49 = X

169 = 100

144.49 = X

144.49 x 100/169 = X

85.5 = X

Therefore, the discount was A) $ 24.51 and B) 14.5% of the value.

Answer:

Step-by-step explanation:

A line that is parallel to the line that goes through (-3, -3) and (-1, 5) will have the same slope as the one we will find when we plug those numbers into the slope formula. Let's do that first:

[tex]m=\frac{5-(-3)}{-1-(-3)}=\frac{5+3}{-1+3}=\frac{8}{2}=4[/tex] so the line we need to write has a slope of 4. Moving on...

If the x-intercept we need is 4, that means that we need to understand what an x-intercept is. The x-intercept exists where y = 0; so what we need to do is to write the equation of the line that has a slope of 4 and passes through the point (4, 0). Doing that:

y - 0 = 4(x - 4) and

y = 4x - 16

Answer:

She will need 5 flats.

She will have 2 plants left over.

Step-by-step explanation:

Since she needs 28 flowers and there are 6 flowers in each plant.

To find the number of flats she needs simply divide 28 by 6

=28/6

=4.67

=Rounding off we get 5

Now we know that she need 5 flats so 5 flats will contain 5*6= 30 flowers total.

Since she has space for 28 flowers only the remainder will be;

30-28=2

Therefore she will have 2 plants leftover.

Answer:

Step-by-step explanation:

The sum of arcs of a circle is 360°. The given conditions tell us arc BC ≅ arc AB, so the four arcs of the circle have ratios ...

  CB : BA : AD : DC = 2 : 2 : 3 : 5

The sum of ratio units is 2+2+3+5 = 12, so each one stands for 360°/12 = 30°. Then the arc lengths are ...

  arc BC = arc BA = 60° . . . . 2 ratio units each

  arc AD = 90° . . . . . . . . . . . . 3 ratio units

  arc DC = 150° . . . . . . . . . . . .5 ratio units

The inscribed angles are half the measure of the intercepted arcs:

  ∠ADC = (1/2) arc AC = 1/2(120°) = 60°

  ∠ADP = 1/2 arc AD = 1/2(90°) = 45°

The angles at E are half the sum of the measures of the intercepted arcs.

  ∠AEB = (arc AB + arc CD)/2 = (60° +150°)/2 = 105°

Angle P is half the difference of the intercepted arcs.

  ∠P = (arc BD -arc AD)/2 = (210° -90°)/2 = 120°/2 = 60°

__

In summary, ...

  arc BC = 60°

  m∠ADC = 60°

  m∠AEB = 105°

  m∠ADP = 45°

  m∠P = 60°

it is 25÷b for this question.
