Answer:

b =  2A

         h

Step-by-step explanation:

A=bh/2

2A = bh

b =  2A

          h

Answer:

b=(2a)/h

Step-by-step explanation:

Multiply both sides by 2

2A=bh

Divide both sides by h

(2a)/h=b

Answer:

45 I'm pretty sure. so it 45

Answer:

The figure is 5.5in^2.

Step-by-step explanation:

To find the area of the triangle portion, we will use the formula for area of a triangle, [tex]\frac{bh}{2}[/tex], where b = base and h = height.

So lets find our variables,

b = 3

h = 3

So we can plug that into our equation and find the area,

3 · 3 = 9 and 9 ÷ 2 = 4.5

So the area of the triangle is 4.5in^2

To find the area of the square portion, we will use the formula for the area of a square or rectangle, l · w, where l = length and w = width

So lets find our variables,

l = 1

w = 1

So 1 · 1 = 1in^2

To find the total area we will add the areas of the two components together,

4.5 + 1 = 5.5in^2

So the area of the total figure is 5.5in^2.

Answer:

Given the ratio of copper and zinc in an alloy is 5:3.

Let weight of copper and zinc be 5x and 3x.

Then according to the problem we have,

5x=30.5

or, x=6.1

Then weight of zinc is 3×6.1=18.3 g.

Given :

Martin drinks 1/4 of a litre of juice each day.

Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.

To Find :

Martin buys enough juice to last for 2 weeks (14 days).

What is the lowest price Martin can pay for this juice.

Solution :

Amount of litre used in 14 days is :

V = 14× ( 1/4 )

V = 3.5 liter

Lowest price to pay is :

P = 2 × Cost of one 2 L carton

P = £(2 × 3.60)

P = £7.2

The lowest price Martin can pay for this juice is £7.2 .

Hence, this is the required solution.

Answer is 0.037

Answer:

1. Linear functions are written in the form [tex]mx+b[/tex] whereas exponential functions are written in the form [tex]b^{x}[/tex].

2. Increasing exponential growth functions will rise much quicker than increasing linear functions.

3. Example of a linear function: [tex]y=2x+1[/tex], example of an exponential function: [tex]f(x)=3^{x}[/tex]

Answer:

x=−27/26

and y=−192/13

Step-by-step explanation:

6x+y=−21;8x−3y=36

Step: Solve6x+y=−21for y:

6x+y=−21

6x+y+−6x=−21+−6x(Add -6x to both sides)

y=−6x−21

Step: Substitute−6x−21foryin8x−3y=36:

8x−3y=36

8x−3(−6x−21)=36

26x+63=36(Simplify both sides of the equation)

26x+63+−63=36+−63(Add -63 to both sides)

26x=−27

26x

26

=

−27

26

(Divide both sides by 26)

Answer:

15 is the slope and 70 is the y-intecpet

Step-by-step explanation:

Answer:

(-6,-4)

Step-by-step explanation:

to get to -4 from 2 you have to subtract 6, making the slope x/6 but you said the slope is 3/2. divide 6 by 2 and you get 3. 3x3=9 making the slope 9/6. simplify and you get 3/2

Answer:

$482.50

Step-by-step explanation:

Base salary: $400

5% of 1,650 is 82.50

.05 x 1,650 = 82.50

Commission : $82.50

Equation: 400 + 82.50 = $482.50

Answer:

Option (C)

Step-by-step explanation:

By using regression line calculator,

Equation of the regression line will be,

y = 0.4881x - 0.85714

Here y = Levels passed

x = Number of minutes played

Now we can check every option given.

Option (A)

For x = 2 minutes,

y = 0.4881(2) - 0.85714

  = 0.11906

  ≈ 0.1

False.

Option (B)

For x = 17 minutes,

y = 0.4881(17) - 0.85714

  = 8.2971 - 0.85714

  = 7.44

  ≈ 7th level

False.

Option (C)

For x = 20 minutes

y = 0.4881(20) - 0.85714

  = 9.762 - 0.85714

  = 8.9

  ≈ 9th level

True.

Option (D)

For x = 50 minutes,

y = 0.4881(50) - 0.85714

  = 24.405 - 0.85714

  = 23.54786

  ≈ 24th level

False.

Therefore, Option (C) will be the correct option.
