At Guevarra Clan Reunion, 4 1/2 kg of spaghetti was left.Lf there are 6 families,how much each family can take home equally.How much each family can take home equally?

Answers

Answer:

3/4 kg of sphagetti each

Step-by-step explanation:

The amount each family can take home, if the kg of sphagetti is divided equally is calculated as:

Kg of sphagetti left/Number of families

= 4 1/2kg/6

= 9/2 ÷ 6

= 9/2 × 1/6

= 9/12

= 3/4 kg

Hence, each family can take home 3/4 kg of sphagetti each.

A university wants to build a new residence hall with dorm rooms. The length is 3x+1 ft and the width is x^2-1 ft. If the university wants each room to have 195ft^2 of living space, what should be the dimensions of each dorm room? ["living space confuses me because idk if it's volume or bottom surface area]

Answers

Length of room, l = 3x + 1 ft.

Breadth of room, b = x² -1 ft.

Now, it is given that university wants each room to have 195 ft² of living space.

So,

[tex]lb = A\\\\(x^2-1)(3x+1)=195\\\\3x^3+x^2-6x-1=195\\\\3x^3+x^2-6x-196=0[/tex]

So, above equation has two complex root and one real root i.e x = 4.08 ft .

Therefore, Length of room is 13.24 ft and breadth is 15.65 ft.

Hence, this is the required solution.

H(x) =2x+3 James brought a plant that was 3 inches tall. Each week the plant grew 2 inches. The function h(x) = 2x + 3 describes the height of the plant after x weeks. Which is the reasonable domain for this function?

Answers

Answer:

For 6 weeks, the height will be 15 inches

Step-by-step explanation:

Step one:

given data

the initial height of plant= 3inches

growth in inches per week =2inches per wee

Step two:

for x number of weeks, the height is expressed as

[tex]h(x) = 2x + 3[/tex]

With the given growth function, we can estimate the height of the plant after any number of weeks, say x=6, that is 6 weeks, the height will be

substitute x=6 in the growth function

[tex]h(x) = 2(6)+ 3\\\\h(x) = 12 + 3\\\\h(x) = 15 inches[/tex]

DESCRIBE IN WORDS THE TRANSLATION OF x represented by the translation rule <-6,8> (X) A. 6 units to the right and 8 units down B. 6 units to the left and 8 units up C. 8 units to the left and 6 units down D. 6 units to the right and 8 units up

Answers

Given:

Translation of x represented by the translation rule <-6,8>.

To find:

The correct statement for the given rule of translation.

Solution:

Rule of translation is <-6,8>.

Here, x-coordinate represents horizontal shift and y-coordinate represents vertical shift.

x-coordinate is -6, which is negative. So, the figure translated 6 units left.

y-coordinate is 8, which is positive. So, the figure translated 8 units up.

Thus, translation in words is defined as "6 units to the left and 8 units up".

Therefore, the correct option is B.

Shannon's new car sold for $28,000. Her online research indicates that the car will depreciate exponentially at a rate of 5 ¼ % per year. Write the exponential depreciation formula for Shannon's car.

Answers

Answer:

P = 28,000(0.945)^y

where P is the price of the car after y years of purchase

Step-by-step explanation:

The rate of decrease is 5 1/4 % per year

This is same as 5.5% (5.5/100 = 0.055) per year

The exponential equation will be ;

P = 28,000( 1 - 0.055)^y

P = 28,000(0.945)^y

where y is the number of years after the year of purchase

If the graph of the parent function f(x) = x is shifted 7 units down, which of the following equations would the new graphed line represent?

Answers

Answer:

Option (2)

Step-by-step explanation:

If a function g(x) is shifted 'a' units downwards then the equation of the transformed function will be,

g(x) = f(x) - a

Similarly, when the parent function is shifted 'a' units upwards, equation of the transformed function will be,

g(x) = f(x) + a

If the parent function is f(x) = x

And the graph of this function is shifted 7 units downwards,

Transformed function will be,

f'(x) = x - 7

Option (2) will be the correct option.

Bok Sanctuary in Lake Wales, FL, has a carillon tower that is 205 feet tall. Heather made a scale drawing of the tower using the scale 1 inch : 20 feet. In which proportion does h represent the height, in inches, of Heather's scale drawing?

Answers

Answer:

10.25 inches

Step-by-step explanation:

Given that:

Actual height of tower = 205 feets

Ratio of scale drawing = 1 inch : 20 feets

The proportion of the height of the scale drawing will be :

Actual height / 20 feets

205 feets / 20 feets

= 10.25 inches

h in inches of the scale drawing will be 10.25 inches

I need help, please and thank you. I know that you have to multiply the diameter by 2 to find the radius, but with the 9 pi, it makes me unsure if I'm doing this correctly. ​

Answers

Answer:

r=6

Step-by-step explanation:

The area of a circle is given by πr². Note that this uses the radius, not the diameter.

Now, one quarter of this area (ABC) is given to be 9π.

So apparently:

[tex]\frac14 \pi r^2 = 9\pi[/tex]

If you solve this:

[tex]\frac14 r^2 = 9[/tex] (divide both sides by π)

[tex]r^2 = 9\cdot4[/tex] (multiply both sides by 4)

so

r = √36 = 6

so the radius is 6.
