you will multiply 80 by 40

80×40=3200

Answer:

y = 42 + 7x

Step-by-step explanation:

y=42+7x is the equation  that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

Two or more expressions with an Equal sign is called as Equation.

Given that the temperature at sunrise is 42°F.

Each​ hour, the temperature rises 7°F.

We need to find the equation that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

y=42+7x is the equation  that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

We have to draw the graph by taking few points.

x     0    1      2       3

y    42   49   56    63

Hence, y=42+7x is the equation  that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

Answer:

Step-by-step explanation:

∠B and ∠D are same side interior angles and are supplementary angles ( they add up to 180°) because AB ║CD are cut by transversal BD

5x +4x = 180

9x =180

x= 20

∠B = 5*20 =100°

∠D =4*20 =80°

Answer:

x = -11

m<B = -43

m<C = -22

Step-by-step explanation:

To solve for x, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.

Answer:

x>12

Step-by-step explanation:

1/3(x-6)>2

distribute 1/3

1/3x-2>2

add 2 to both sides

1/3x>4

multiply both sides by 3

x>12

The sales tax rate is 8%.

The correct option is (b).

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Jenny bought scrapbooking supplies for $145.00.

She paid $11.60 in sales tax.

let the tax rate be x%.

So, the price without sales tax = 145 - 11.6 = $133.4

Thus, x% of 133.4 = 11.6

133.4 x = 1160

x = 8.65%

x= 8%

Hence, the tax rate is 8%.

Answer:

I dunno, why?

Step-by-step explanation:

Step-by-step explanation:

first you will put a line in the missing part of the inside of the figure.Once you do you will see that there are two figures.

to find the diagonal of the half-circle : 7cm-2cm-1cm=4cm

Now use the area formulas for each figure.The area of the semicircle is pi×d/2.The area of the rectangle is a×b.

A of semicircle =3.14×4cm/2=6.28cm²

A of rectangle =7×3=21cm²

to find the perimeter of them:

P of semicircle = 3.14×4=12.56cm

P of rectangle =2(7+3)=14+6=20cm
