Answer:

40 ft^2

Step-by-step explanation:

Think of the area of the green rectangle first. Then subtract the area of the smaller brown rectangles.

area of green carpet = 4 ft * 12 ft - 3 ft * 2 ft - 1 ft * 2 ft

area = 48 ft^2 - 6 ft^2 - 2 ft^2

area = 40 ft^2

Answer:

minimum

Step-by-step explanation:

Given a quadratic in standard form f(x) = ax² + bx + c ( a ≠ 0 )

• If a > 0 then vertex is a minimum

• If a < 0 then vertex is a maximum

f(x) = 3x² + 5x + 2 ← is in standard form

with a = 3

Since a > 0 then vertex is a minimum

Step-by-step explanation:

The y intercept cannot possibly where it is shown. The slope is correct. The line is going from the lower left to the upper right, and the 3 makes the line closer to the y axis. For example if x = 1 then y = 3*1+2 = 5.

If x = 2, then y = 3*2 + 2 = 8 so each move of x makes a huge difference in where y is.

So lets go back to the y intercept. When x = 0, then y = 2. y = 2 is about the x axis, not below it.

Shona's drawn line cannot be the representation of her equation y = 3x + 2, as the y-intercept of her drawn line is negative, while the y-intercept of the equation is positive (b = 2).

The equation of a line of the form y = mx + b shows a line on the coordinate plane, where for every value of x, we get a particular value of y, and m is the slope of the line. The slope is the value of tan θ, where θ is the positive angle formed between the x-axis and the line. b is the y-intercept. The y-intercept is the value of y when x = 0. This signifies that the line passes through the point (0, b).

We are given an equation of a line y = 3x + 2, and a line of the coordinate plane.

We are asked to give the reason why the line on the plane is not the representation of the given equation.

The equation y = 3x + 2, when compared to the slope-intercept form of a line, y = mx + b, shows that the slope m = 3 and the y-intercept b = 2.

The line on the plane has a positive slope, so m = 3 can be its slope.

But the y-intercept of the drawn line is negative since it is below the origin. So b = 2 cannot be its y-intercept.

(Value of y is positive above the origin and negative below the origin)

(Value of x is positive to the right of the origin and negative to the left of the origin)

∴ Shona's drawn line cannot be the representation of her equation y = 3x + 2, as the y-intercept of her drawn line is negative, while the y-intercept of the equation is positive (b = 2).

Answer:

14 possible outcomes

Step-by-step explanation:

It is given that :

There are 8 black cards numbered 1 through 8.

Therefore, Black 1, Black 2, Black 3, Black 4, Black 5, Black 6, Black 7, Black 8.

And there are 6 red cards numbered 1 through 6.

Therefore, Red 1, Red 2, Red 3, Red 4, Red 5, Red 6.

So the total number of cards is 8 + 6 = 14 cards.

So, there will be 14 possible outcomes if we choose a card randomly.

Answer: 30

Step-by-step explanation: I think the height of the triangle is 30 cm because the rectangle has dimensions of 3 cm and 10 cm so I multiplied that which equals 30 then I thought 6 x 5 = 30 so 30 cm

btw, if i'm wrong please don't get mad, i'm trying my best lol

Answer:

H=10

Step-by-step explanation:

First, let's find the area of the rectangle:

L*W

the length is 3 and the height is 10 so substitute and you get:

10*3 = 30

now let's find what the area of the triangle should be:

B*H/2  =30(because the area is the same)

the base is 6 and the height is unknown, now lets fully substitute:

6H/2=30

3H=30

H=10

Hope this helps :)

Answer:

area = 2184 ft²

Step-by-step explanation:

height² = 60² - 36² = 3600 - 1296 = 2304

height = √2304 = 48

base = 36 + x

x² = 73² - 48² = 5329 - 2304 = 3025

x = √3025 = 55

base = 36 + 55 = 91

area = 1/2(h)(b) = 1/2(48)(91) = 2184 ft²

Answer:

Sec <K  = 37/12

Step-by-step explanation:

Given the following measure

∠L=90°

LK = 12

KJ = 37, and

JL = 35.

Considering angle K

JL = opposite

KJ =hypotenuse

LK = adjacent

Using SOH CAH TOA identity

Cos theta = adj/hyp

Cos m<K = LK/KJ

cos m<K = 12/37

Since sec theta = 1/cos thets

Sec <K = 1/cos<K

Sec <K = 1/(12/37)

Sec <K  = 37/12

That is going to be a looong answer...

Answer:

174 rpm

Step-by-step explanation:

The question says that the speed is inversely proportional to the length. Thus, Inverse means, as the diameter increases, the speed reduces, or as the diameter reduces, the speed increases.

Thus, from the question, if diameter A is 20, and B is 10, then definitely, the speed will increase from 348 to a higher rate. Mathematically, we have

20 / 10 = 348 / x, where x is the missing speed.

2 = 348 / x

x = 348 / 2

x = 174 rpm

Therefore, the pulley A must have been running at a speed of 174 rpm

Answer: 16 gallons

Step-by-step explanation:

Since we are given the information that 1/4 of the gas is left, it simply means that (1 - 1/4) = 3/4 has been used.

The tank was filled and this was 12 gallons of gas.

Let the gas that the tank hold be represented by x. Therefore,

3/4 of x = 12

3/4 × x = 12

0.75x = 12

x = 12/0.75

x = 16

The tank holds 16 gallons of gas.

Answer:

The end behavior of f(x)=2/3x-2 is: as x->+ infinity, f(x)->+ infinity

as x->- infinity, f(x)->- infinity

Step-by-step explanation:

When you are asked about the end behavior of a function, look to see where the function is traveling on the graph. For instance, this graph is linear, so you should look to see if the slope is positive or negative. This linear function is positive, so as x is reaching positive infinity the f(x) would also be reaching positive infinity. As x is reaching negative infinity, f(x) would also be reaching negative infinity. The end behavior of a function describes the trend of the graph on the left and right side of the x- axis. (As x approaches negative infinity and as x approaches positive infinity).  

Answer:

donuts:  $5.00

croissants: $9.00

Step-by-step explanation:

c - croissants

d - donuts

(1) 3d + 5c = 60        

(2) 4d + 5c = 65

solve for 5c in equation (1)

5c = 60 -3d

substitute 5c = 60-3d into (2)

4d + (60 - 3d) = 65

d + 60 = 65

d = 5      

to find c substitute d = 5 into (1)

3(5) + 5(c) = 60

15 + 5c = 60

5c = 45

c = 9
