Choose ALL the angles with a measure of 90°.

Answer:

  55

Step-by-step explanation:

We can use the given relations to write an equation that can be solved for my age 25 years from now.

__

Let x represent my age in 25 years. The age relationships can be summarized as ...

We know 10 years ago my dad was 4 times my age, so we have ...

  4(x -35) = 3x -85

  4x -140 = 3x -85 . . . eliminate parentheses

  x = 55 . . . . . . . . . . . add 140-3x

I will be 55 in 25 years from now.

_____

Additional comment

10 years ago, I was 20 and my dad was 80. Now, I'm 30 and my dad is 90. In 25 years, I'll be 55.

Answer:

10.5

Step-by-step explanation:

Answer:

Step-by-step explanation:

3,16, 7, 19, 1, 12, 3,9,16,12

First list in ascending order:

= 1 3 3 7 9 12 12 16 16 19

The median is the mean of the middle 2 numbers:

Median = (9 + 12) / 2 = 10.5.

Answer:

G is true is out divide 1/7 by 2 out get 1/14

H is false the product is always 1

I is false all numbers have a reciprocal besides 0

Answer:

g. True

h. False

i. False

Step-by-step explanation:  

g.  

[tex]\frac{1}{14}[/tex] is half of [tex]\frac{1}{7}[/tex]  

This would be true because half of a number can be found by multiplying by [tex]\frac{1}{2}[/tex]  

If you multiplied [tex]\frac{1}{7} * \frac{1}{2}[/tex]  

The numerator is 1 * 1 which is 1  

And then the denominator is 7 * 2 which is 14  

That would give you [tex]\frac{1}{14}[/tex]

h.  

The products of two reciprocals is 0  

This is not true  

Reason being, reciprocals are just the number flipped. If you times the number by itself, you don't get 0, you get 1.  

Ex:  [tex]\frac{2}{8}[/tex]

Its reciprocal is [tex]\frac{8}{2}[/tex]  

So multiply them together

[tex]\frac{2}{8}* \frac{8}{2}[/tex]  

2 * 8 = 16  

8 * 2 = 16  

[tex]\frac{16}{16} = 1[/tex]

i.  

A whole number does not have a reciprocal  

This is incorrect. If you think about it, a whole number is just the number, over 1  

Ex: [tex]\frac{6}{1}[/tex]

This is still a whole number even though its written in fraction form because if you divide 6 by 1, your still going to get 6.

If you an write it as a fraction, it has a reciprocal.

The reciprocal in this case would be [tex]\frac{1}{6}[/tex]

Answer:  a) 236 ml  b) 94.4 %

Step-by-step explanation:  a) in 44 % solution there is 0.44 · 25 ml = 11 ml.

Total volume of acid is 225 ml + 11 ml = 236 ml

b) vol-% of acid is 236 ml /(225 ml + 25 ml) · 100 % = 94.4 %

The milliliters of acid that are in the resulting mixture is 236 millimeters and the percentage of the resulting mixture is acid is 94.4%.

a. The milliliters of acid are in the resulting mixture will be:

= 225 ml + (44% × 25ml)

= 225ml + (0.44 × 25ml)

= 225ml + 11ml

= 236ml

b. The percentage of the resulting mixture that is acid will be:

= [(236ml / (25ml + 225ml)] × 100

= (236ml/250ml) × 100

= 94.4%

Answer:

  254 in

Step-by-step explanation:

The Law of Sines tells you ...

  g/sin(G) = h/sin(H)

  g = h(sin(G)/sin(H)) = 510 in(0.42262/0.84805)

  g ≈ 254.15

The length of g is about 254 inches.

The probability of the sample from 10 to 25 will be 60%. Then the correct option is B.

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

Based on the density graph below.

Then the probability of a value in the sample space being anywhere from 10 to 25 will be

P = (25 - 10)/(25 - 0)

P = 15/25

P = 0.6

P = 60%

Thus, the probability of a value in the sample space being anywhere from 10 to 25 will be 60.

Hence the correct option is B.

Answer:

13

Step-by-step explanation:

starting equation is 15=0.75(x)+5.

You have to have the numbers on one side so...

15-5=10, and 5-5=0.

now, our equation is 10=0.75(x).

we are looking for x, so....

10/.75= 13 and 1/3.

since there is no such thing as a third of a song, 13 would be our number.

Answer:

0.9609

Step-by-step explanation:

Margin of error is expressed using the formula;

M = z * √s²/n

z is the 95%  z score = 1.96

s is the standard deviation = 2.5

n is the sample size  = 26

M = 1.96 * √2.5²/26

M = 1.96 * √0.2404

M =  1.96 * 0.49029

M = 0.9609

Hence the margin of error is 0.9609

Find the measure of each angle indicated.

○ 44°

○ 68°

○ 59°

○ 100°

We will simply substitute the given values in the formula,

⇒ Sum of all angles of a Quadrilateral = 360°

⇒ ∠S + ∠T + ∠Q + ∠R = 360°

Substituting the values given, We get,

⇒ 95° + 85° + 80° + ∠R = 360°

Calculating further, We get,

⇒ 260° + ∠R = 360°

Transposing 260° to Right Hand Side, We get,

⇒ ∠R = 360° - 260°

Calculating further, We get,

⇒ ∠R = 100°

∴ ∠R = 100°

The measure of ∠R is 100°

Hence, Last option i.e., 100° is correct answer.

Curve is concave downward when the second derivative is negative.

y' = [tex]\frac{x^{2} }{x^{2} -x+4}[/tex] , by the Fundamental Theorem of Calculus

y'' =   [tex]\frac{-x^2+8x}{\left(x^2-x+4\right)^2}[/tex] , which has a denominator that is always positive. The numerator [tex]-x^2+8x[/tex] is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.
