Answer:

Age of Father- 36

Age of Son- 10

Answer:

62

Step-by-step explanation:

In this scenario, we would use BODMAS to determine where to start.

B - Brackets

O- Of

D - Division

M - Multiplication

A - Addition

S - Subtraction

First, let's start with the brackets.

16 X [tex]\frac{1}{2}[/tex] is the same as 16 X 0.5.

16 X [tex]\frac{1}{2}[/tex] = 8

Next is the division sum.

32 ÷ 4 = 8

Afterwards, we multiply both answers.

8 X 8 = 64

Your answer is then minused by 2 and leads to the final answer.

64 - 2 = 62

Answer:

34)  5 questions

35)  8 questions

36)  9 questions

37)  10 questions

Step-by-step explanation:

We could create an exponential function for this scenario, but it is quicker and easier to simply list the potential scores.

We are told that the initial score is 1.

We are told that the the score doubles each time.

Therefore, the scores in sequence are:  
1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 ... etc.

34)  16 is the 5th term in the sequence, so 5 questions

35)  128 is the 8th term in the sequence, so 8 questions

36)  256 is the 9th term in the sequence, so 9 questions

37)  512 is the 10th term in the sequence, so 10 questions

Answer: 234 degrees

Step-by-step explanation:

Angle formed by a chord and a tangent has half the measure as the arc formed by the chord

The value of measure of arc DEF is,

⇒ 234 degree

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Line t is tangent to the circle.

Hence, We know that;

The angle formed by a chord and a tangent is equal to 1/2 the measure of the intercepted arc.

Thus, The value of measure of arc DEF is,

⇒ 2 x 117 degree

⇒ 234 degree

The ladder and the outside wall form a right triangle

The length of the ladder is 97.8 feet

The given parameters are:

Distance (B) = 22 feet

Angle of elevation (θ) = 77 degrees

The length (L) of the ladder is calculated using the following cosine ratio

cos(θ) = B/L

So, we have:

cos(77) = 22/L

Make L the subject

L = 22/cos(77)

Evaluate the product

L = 97.8

Hence, the length of the ladder is 97.8 feet

Answer:

x= -2

Step-by-step explanation:

Make denominator same

3*(x+10)/12 - 2*(x-10)/12 = 6*(x+10)/12

denominators are same so numerators has to same as well

3*(x+10)-2*(x-10)=6*(x+10)

expand brackets

3x+30-2x+20 = 6x+60

x+50=6x+60

x-6x=60-50

-5x=10

x= -2

Explanation:

The sum of g and h is the result of adding them. That means we have g+h so far. We reduce it or shrink that result by 11, which indicates we subtract off 11. Therefore, we end up with g+h-11

89.09% of books will weigh 11 pounds or more, then the number of books will be 129.

The z-score is a numerical measurement used in statistics to refer to how much a given value differs from the standard deviation.

The weights of books in a bookcase are normally distributed with a mean of 11.6 pounds and a standard deviation of 1.3 pounds. There are 136 books on the bookshelf.

Then the z-score when the books will weigh 11 pounds or more will be

[tex]z= \frac{11-13.5}{2.3} \\\\z= -1.0869[/tex]

Then the probability will be

[tex]P(x > 11) = 1-P(x < 11 ) = 0.8909[/tex]

89.09% of books will weigh 11 pounds or more, then the number of the books will be

=145 × 0.8909

=129.1805 ≈ 129

The first step when rewriting y = 6x2 + 18x + 14 in the form y = a(x – h)2 + k is to factor out 6 from the first two terms

The standard vertx form of an expression is given as  y = a(x – h)^2 + k

Given the quadratic expression given as:

y = 6x^2  + 18x+ 14

Before a quadratic equation can be transformed to its vertex form, the coefiicient of x^2 must be 1.

To do that, you will factor out 6 from the first two terms to have:

6(x^2 + 3x) + 14

Hence the first step when rewriting y = 6x2 + 18x + 14 in the form y = a(x – h)2 + k is to factor out 6 from the first two terms

Step-by-step explanation:

Answer:

308 in³, 101 in³ (from left to right)

Step-by-step explanation:

Volume of cylinder= πr²h, where r is the radius and h is the height.

Cylinder on left

radius= 7 in

height= 2 in

Volume

= π(7²)(2)

= 98π

= 308 in³ (3 s.f.)

Cylinder of right

radius= 4 in

height= 2 in

Volume

= π(4²)(2)

= 32π

= 101 in³ (3 s.f.)

Answer: First portion is greater than second portion.

Step-by-step explanation:

Time taken to hiked down a trail = 10 minutes

Change in elevation = (-) 170 feet

Speed is given by

\begin{gathered}Speed=\frac{Distance}{Time}\\\\Speed=\frac{170}{10}\\\\Speed=17\text{ feet per minute}\end{gathered}

Speed=

Time

Distance

Speed=

10

170

Speed=17 feet per minute

Similarly,

Time taken to hiked down a trail = 20 minutes

Change in elevation = (-)220 feet

Speed is given by

Speed=\frac{Distance}{Time}Speed=

Time

Distance

\begin{gathered}Speed=\frac{220}{20}\\\\Speed=11\text{ feet per minutes}\end{gathered}

Speed=

20

220

Speed=11 feet per minutes

So, we can see that first portion of the hike where he hiked down a trail at a steady rate for 10 minutes and her change in elevation was (-) 170 feet, was her rate of change in elevation greater.

As 17 feet per minutes is greater than 11 feet per minutes.

Answer:

23.14

Step-by-step explanation:

The semi circular region's diagram looks as if it is half of a circle, cut in half by its diameter.

So the circumference of a circle is 2πr or πd

This is half a circle, so the formula is πd/2

π9/2  =  14.137

However, that's only half of the circumference. That does not contain the diameter that is also included.

So if you add 9m to that you get 23.137
