Given phrase - 66 less than twice Greg's age

In the given phrase, "twice" means "double", which means "2 times".

In the given phrase, "less than" means "subtraction in reverse form".

Reversing the expression, we get:

The question has stated that "Greg's age" will be represented as "g". Let's substitute "Greg's age" as "g". Then,

Therefore, the expression that represents the phrase is 2g - 66.

Answer:

C. y = 3x -2

Step-by-step explanation:

y = mx + b

start with b, the y-intercept, which is -2.

Next find m, the slope. From -2 on the y-axis you are going to find the slope by doing rise/run. You will rise 3 units and run 1 unit to get to the next point on the line.

The equation is y = 3x -2

The practical domain of function f(x) has all positive integers and all whole numbers that are multiples of 4 that is option A or D is correct

The domain is "set of all possible inputs value for the function".

According to the question,

A package of buttery round crackers contains 4 sleeves of crackers each

package of crackers cost $2.49. A function f(x) written to represent the cost of purchasing x packages of crackers.

In order to find the practical domain for the function f(x) only if analysis the value of domain function 'x' must positive number so contain 'all positive integers' and since a package of buttery round crackers contains 4 sleeves then domain must contain 'all whole numbers that are multiples of 4'.

Hence, the practical domain of function f(x) has all positive integers and all whole numbers that are multiples of 4.

Step-by-step explanation:

According to the attachment

⠀

let AB be the ladder

BC be the distance between the ladder and wall

⠀

(a) We have to find ∠A by trigonometry formula

[tex] \sf \sin A = \frac{perpendicular}{hypotenuse} [/tex]

Here angle A is facing BC so it is perpendicular

and AB is the longest side so it is hypotenuse

[tex] \sf \implies \sin A = \frac{BC}{AB} \\ \\ \\ \sf \implies \sin A = \frac{9}{20} \\ \\ \\ \sf \implies \sin A = 0.45 \\ \\ \\ \sf \implies \sin A = \sin27{ \degree} \\ \\ \\ \sf \purple {A = 27{ \degree}}[/tex]

(b)

AC is the distance from the upper end of the ladder to ground

we will find it by Pythagoras theorem

[tex] \sf {hypotenuse}^{2} = {perpendicular}^{2} + {base}^{2} \\ \\ \\ \sf \implies {AB}^{2} = {BC}^{2} + {AC}^{2} \\ \\ \\ \sf \implies {20}^{2} = {9}^{2} + {AC}^{2} \\ \\ \\ \sf \implies 400 = 81 + {AC}^{2} \\ \\ \\ \sf \implies 400 - 81 = {AC}^{2} \\ \\ \\ \sf \implies 319 = {AC}^{2} \\ \\ \\ \sf \implies \sqrt{319} = AC \\ \\ \\ \sf \blue{\implies 17.86 = AC}[/tex]

Answer:

110°

Step-by-step explanation:

if we're looking for the bearing of C from A, the angle should be formed at A

then, starting from the north poles, move in a clockwise direction till you meet the line coming from C . then, sum up the angles involved.

which is = 45°+ 65° = 110°

therefore, the bearing of C from A is 110°

Answer:

2,3,7 are the prime factorization of number of 252

Hi Student!

Prime factorization is the process of stripping down a number to it's basic elements.  We take a number and bring it down the most we can.  For example we take 4 and make it 2 x 2.  In this case we are given a number of 252 so we can began by dividing by 2.

[tex]252 / 2[/tex]

[tex]126[/tex]

Looking at the numbers that we have now, 126 x 2, we can see that 126 can still be divisible by another 2 so lets do that again.

[tex]126 / 2[/tex]

[tex]63[/tex]

Now, looking at the numbers that we have, 63 x 2 x 2, we see that we can no longer divide it by a 2 because 63 is not divisible by 2.  However, we can divide 3 away from the number so lets do that.

[tex]63 / 3[/tex]

[tex]21[/tex]

Once again, looking at the numbers that we have, 21 x 3 x 2 x 2, we see that we can once again divide a 3 away from our first number so lets do that again.

[tex]21 / 3[/tex]

[tex]7[/tex]

Finally, we have come down to the last line where our final elements are 7 x 3 x 3 x 2 x 2.  This is our prime factorization of the number 252 and this is where we can conclude our solution seeking.

Answer: s + 30 ≥ 50; s ≥ 20

Step-by-step explanation:

let s be the amount you have yet to spend in order to reach $50 or more

you already have $30.

This means you need to spend at least $20 more ($50 - $30 = $20)

S can be greater than or equal to $20 because your total will be 50 or more, therefore qualifying for the discount.

The average of a group of numbers is simply defined as the mean. In statistics, the mean is regarded as one of the indicators of central tendency.

Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week.

Fourteen people answered that they generally sell two cars; nineteen generally sell three cars; twelve generally sell four cars; nine generally sell five cars; eleven generally sell six cars.

the area of a circle is

that is for the whole circle, which is the same as 360 degree arc.

now that we have only 254 out of the total of 360 degrees, the sector area is

pi×r² × 254/360

pi×9² × 254/360 = pi×9 × 254/40 = pi×57.15 =
