Rebecca decides that this building will be too small at a scale of 1 cm = 3 m. She changes the plan to be at a 1 cm = 4 m scale. What will be the area of the circular pool when it is constructed at this scale?

Answer:

y=k/x

Step-by-step explanation:

Answer:

22 degrees

Step-by-step explanation:

The total degree of a triangle is 180 degrees.

we are given two degrees already; 90 degrees (from the right angle sign) and 68 degrees from the problem. If we create an equation to reflect this we can find the missing angle:

180 = 90 + 68 + x

180 = 158 + x

x = 22

Step-by-step explanation:

<TSU=68

<STU=90

<SUT=

90+68=158

180-158=22

Answer:

3 [tex]\frac{8}{9}[/tex]

Step-by-step explanation:

Answer:

1: y=(3x/2)-4  2 :y=(-x/13)+(15/13) 3: y = 13x+55

Step-by-step explanation:

1:

Begin by finding slope

m = (y2-1)/(x2-1)

(-7-(-4)/(-2-0) = 3/2

next use point slope form

y-y1 = m(x-x1) (you can pick any point to use, I will use (0,-4)

y-(-4) = 3/2(x-0)

y+4 = 3x/2

y=(3x/2)-4

2:

The slope of the line y=13x+2 is 13

Take the opposite sign and reciprocal of 13 to get the slope of the line perpendicular; in this case it's -1/13

Next, just like in problem 1, use point slope form.

y-1 = (-1/13)(x-2)

y-1 = (-x/13)+(2/13)   (convert 1 to 13/13 for like terms and bring over to the left side)

y=(-x/13)+(15/13)

3:

the intercept will be $55 since it's the initial amount

you know that you deposit some amount every week so set this up as an equation

$133 = m(6)+$55     (the amount deposited every week times 6 +the initial $55 will equal $133)

solving for m gets you $13

so the equation is y = 13x+55

plug in 6 for x to check; 13x6 + 55 = 133

hope this helps

Answer:

Look at step-by-step explanation.

Step-by-step explanation:

First write everything in terms of sin and cos:

(sinx)(sinx/cosx) + (sinx)/(sinx/cosx) = (1/cosx)

Then simplify the expression where you can:

(sin^2)/(cosx) + (cosx) = (1/cosx)

Next find a common denominator and add the two numbers on the left side of the equation:

(sin^2)/(cosx) + (cos^2x)/(cos^2x) = (1/cosx)

((sin2^x)+(cos2^x)/(cosx)) = (1/cos)

Finally, use the identity, sin2^x + cos2^x = 1, to simply to numerator:

(1/cosx) = (1/cosx)

Answer:

The answer is A -3 is greater than y and y is less than 3

Step-by-step explanation:

I'm not really sure how to solve these either, but if you type the equations into desmos graphing calculator just make sure the highlighted area in desmos is the same as the points on your question and it will be correct.

Answer:

the y axis will be 1 and the x axis will be 8

I know that the y axis will be 1 because y=1  and I know that the x axis will be 8 because 2 to cubed will be 8 because when you multiply 2 by 2 you get 4 and when you multiply 4 by 2 the answer will be 8 so the axis will be (1,8)

Answer:

Maximum of 50 persons

Step-by-step explanation:

Straight line equation

let the total prices be y

and the number of persons be x

1.  Brenda's Bridal Catering charges

the expression for the charges is

y=mx+c

y=18x+300---------------1

2.  Sarah's Complete Catering charges

the expression for the charges is

y=mx+c

y=15x+450---------------2

equating 1 and 2 we can then solve for the number of guest as

18x+300=15x+450

18x-15x=450-300

3x=150

divide both sides by 3

x=150/3

x=50

x<=50

Therefore she can invite a maximum of 50 persons

Answer: 4

Step-by-step explanation:

from point (0,-4), it goes up 4 and over 1, ending at point (1,0)

Answer:

4

Step-by-step explanation:

count the amount of spaces(or lines) to where the second point is(4) and the go right (1) 4/1 simplified is 4.

plz mark brainiest =)

Answer:

just angle E

it could have 3 different names tho

1 ADE

2 CEB

3 E

so it could be either of them

Answer:

It is C. I think

Step-by-step explanation:

A. will just make the investment smaller, not bigger, so not A. It is not B. because it does not give us the result we want. It's not D. because it is too high of an answer. I think it's C. I hope this helps, and I hope it's not wrong, but I do not think it is.

Answer:

B. y=1/3x+4

Step-by-step explanation:

The graph shows a line with a slope of -3. Perpendicular slopes is the reciprocal with a different sign (positive or negative). The perpendicular of -3 is 1/3, and B. is the only option with this slope.

Step-by-step explanation:

Answer:

Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.

Step-by-step explanation:

Zoey made 9 1/2 cups of trail mix for a camping trip.

She wants to divide the trail mix into 3/4-cup servings.

Thirteen people are going on the camping trip.

This means :

1 person = 3/4 cup servings

13 people = x

Cross Multiply

13× 3/4

= 39/4

= 9 3/4 cup

So for Zoey to be able to serve 13 people the trail mix in 3/4 cup servings, she need 9 3/4 cups of the trail mix

From the she made 9 1/2 cups of the trail mix.

Hence, Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.

Answer:

62.5

Step-by-step explanation:

y∞x

y=kx( where k is the constant)

75=6k

75÷6 =k

12.5=k

therefore the relationship between k,x and y is y=12.5x

y=12.5×5

y=62.5
