Answer: 320

Step-by-step explanation:

Coterminal means it is in the same place on the Unit Circle but with one or more rotations clockwise or counterclockwise.

Note: one rotation is 360°

-760 + 360 = -400

-400 + 360 = -40

-40 + 360 = 320

320 is between 0 and 360 so this is the angle we are looking for!

A plot of land is valued at $18,000.Land tax is charged at the rate of 0.70 per $100. What is the total amount of tax paid for t

Vladimir [108]

Answer:

The total amount of tax paid for the land was $126

Step-by-step explanation:

Proportions

The land tax charged is 0.7 per each $100 of the land value. For easy calculations, we find the ratio or proportion to be applied to the value of the land as:

0.7 / 100 =0.007

This factor can be used to obtain the tax charged for a given value of the land.

The plot of land of the question is valued at $18,000.

The tax charged is, then:

0.007*18,000 = 126

The total amount of tax paid for the land was $126

Matteo has &400 in his saving account. on average he spends $10 per week on buying apps. Luca has $200 in his savings accoun

Pavel [41]

Answer:

8 weeks

Step-by-step explanation:

Given data

Matteo

Amount= $400

Spending per week= $10

Hence his balance after x weeks is given as

y=400-10x-------------1

Luca

Amount= $200

Spending per week= $15

Hence his balance after x weeks is given as

y=200+15x-------------2

Equate 1 and 2

400-10x=200+15x

collect like terms

400-200=15x+10x

200=25x

x= 200/25

x= 8 weeks

Hence it will take 8 weeks

I need help finding the inverse of this problem

fomenos

$y=\sqrt{x-1}+6$

(Notice that we always have $y\ge6[tex].)Swap [tex]x$ and $y$ , then solve for $y$ :

$x=\sqrt{y-1}+6$

$x-6=\sqrt{y-1}$

$(x-6)^2=(\sqrt{y-1})^2$

$(x-6)^2=y-1$

$y=(x-6)^2+1$ (this is the inverse)

###

This inverse is valid only for $x\ge6$ . Why?

Suppose we take $x=0$ . Then

$y=(0-6)^2+1=37$

This would suggest that in the original equation, we should get $x=37$ when $y=0$ . But when we check this, we end up with

$0=\sqrt{37-1}+6=\sqrt{36}+6=6+6=12$

which is clearly not true.

A window frame has a length of (5x+3) inches an a width of (x+6) inches. The area of the glass in the window is (4x^2+26x+15) sq

boyakko [2]

ANSWER

the area of the trim around the glass in the window is option ( D)

i.e (x²+7x+3)

REASON

As given in the question

A window frame has a length of (5x+3) inches an a width of (x+6) inches.

As the shape of the window in the form of rectangle.

Formula

Area of the rectangle = length × breadth

put the value in the above equation

we get

Area of window = (5x+3)× ( x + 6)

= 5x² + 33x + 18 inches²

As given in the question

The area of the glass in the window is (4x²+26x+15) square inches.

Area trim around the glass in the window = area of the window - area of the glass.

put the value

we get

= ( 5x² + 33x + 18 ) - ( 4x²+26x+15)

= 1x²+ 7x + 3 inches²

therefore the correct option is (D)

Hence proved
