Answer:

d = 4

Step-by-step explanation:

Answer:

d = 4

Step-by-step explanation:

–24 + 12d = 2(d – 3) + 22

–24 + 12d = 2d - 6 + 22

–24 + 12d = 2d + 16

–24 + 12d - 2d = 16

12d - 2d = 16 + 24

10d = 16 + 24

10d = 40

d = 4

Answer:

C. 4

Step-by-step explanation:

The formula of slopes is: y2 - y1/x2 - x1

m = y2 - y1/x2 - x1

m = 15 - 7/5 - 3

m = 8/2

m = 4/1

m = 4

The slope of the line through the points (3,7) and (5,15) is  4 .

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.

Δy =  change in y coordinate  = y2 - y1

Δx = change in x coordinate = x2 - x1

m = Δy/Δx

where,

m is the slope  

According to the question

Points (3,7) and (5,15)

therefore,

(x1,y1) =  (3,7)

(x2,y2) =  (5,15)

Now ,

The slope of the line  

Using slope formula

m = Δy/Δx

Δy = y2 - y1  

Δy = 15 - 7

Δy = 8

Δx =  = x2 - x1

Δx = 5 - 3  

Δx = 2

Therefore,

m = [tex]\frac{8}{2}[/tex]

m = 4

Hence, the slope of the line through the points (3,7) and (5,15) is  4 .

I'm a simp who watches the simpsons and lives a simplistic lifestyle.

x to y can be expressed as a fraction this way: x/y.

Let x = 12

Let y = 18

12/18

We can now reduce to lowest terms.

Dividing 12 and 18 by 6, we get 2/3 as the final answer.

The simplified fraction is 2/3. This means that the ratio of 12 to 18 can be expressed as 2/3. It indicates that for every 2 units of the first quantity (12), there are 3 units of the second quantity (18). Simplifying the fraction ensures that there are no common factors other than 1 between the numerator and the denominator, making it the simplest representation of the ratio.

To express the ratio 12 to 18 as a fraction in simplest form, we can divide both numbers by their greatest common divisor (GCD). The GCD of 12 and 18 is 6. By dividing both numbers by 6, we simplify the fraction to its simplest form:

12 ÷ 6 = 2

18 ÷ 6 = 3

Thus, the simplified fraction is 2/3. This means that the ratio of 12 to 18 can be expressed as 2/3. It indicates that for every 2 units of the first quantity (12), there are 3 units of the second quantity (18). Simplifying the fraction ensures that there are no common factors other than 1 between the numerator and the denominator, making it the simplest representation of the ratio.

Answer:

The inner surface area is: 1923.25 cm²

Step-by-step explanation:

A hemispherical bowl is made of brass has an inner diameter of 35 cm.

i.e. d = 35 cm

As the radius is basically half of the diameter.

r = d/2

  = 35/2

   = 17.5 cm

The inner surface area of a hemispherical bowl = 2πr²

= 2(3.14)(17.5)²

=1923.25 cm²

Therefore, the inner surface area is: 1923.25 cm²

Answer:

7.5 miles

Step-by-step explanation:

5 miles in 80 km

Total distance = 120 km

120- 80= 40 km

80 km = 5miles

1 km = 5miles/ 80km

120 km = 5/80 * 120 km = 7.5 miles

This is called unitary method. First we find 1 km by dividing the miles with the number of km and then multiply the number of km to find the total number of miles.

Total distance = 120 km

120- 80= 40 km

if there are 5 miles in 80 km then there will be half of the miles in half of the km . So there will be 2.5 miles in 40 km .

So the total number of miles would be

40+80 km= 5+ 2.5 miles

120 km = 7.5 miles

Answer:

The equation of altitude AD drawn from A to BC will be:

[tex]y=x+3[/tex]

Step-by-step explanation:

Let m₁ and m₂ be the slope of line AD and BC respectively.

Now, AD⊥BC

​∴ m₁ × m₂ = -1

be the slope of line AD and BC respectively.

⇒ m₁ = -1/m₂    → (A)

Finding the slope of BC using points

B(2, 2)

C(6, - 2)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(2,\:2\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)[/tex]

[tex]m_{2} =\frac{-2-2}{6-2}[/tex]

[tex]m_{2} =-1[/tex]

On substituting the value of m₂ in equation (A)

m₁ = -1/m₂

    = -1/(-1)

    = 1

We know that the point-slope form of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

∴ Equation of altitude AD passing through A(-2, 1) with slope 1 will be

[tex]y-1=1\cdot \left(x-\left(-2\right)\right)[/tex]

[tex]y-1=x+2[/tex]

[tex]y=x+3[/tex]

Therefore, the equation of altitude AD drawn from A to BC will be:

m<6=   35 degrees

I hope this helps and good luck!

Answer:

m∠4 = 57°

m∠5 = 123°

m∠6 = 35°

Step-by-step explanation:

m∠4 ≅ ∠57°

Therefore m∠4 = 57°

Following this rule of thumb

m∠6 ≅ 35°

m∠6 = 35°

m∠5 = 180 - 57

m∠5 = 123

Answer:

Step-by-step explanation:

If the velocity of a falling body varies directly as the time of flight, this is expressed as;

v α t

v = kt

k = v/t

If at t = 2secs, v = 64.4ft/s

k = 64/2

k = 32 ft

To get the velocity at the end of 5 secs, we will say;

at t = 5secs v = ?

From the formula;

v = kt

v = 32(5)

v = 160ft/s

Hence the required velocity is 160ft/s

I don't really understand it very well

It will take 10 people working 10 hours per day about 2.5 days to make 10 units of the product.

From the statement of the question; 15 people working 5 hours per day can make 30 units of a product in 10 days. Hence, the number of units that can be made in a day is;

Number of units per day = (15*5*10)/30

= 25 units/day

Now; if 10 people make 10 units, working 10 hours per day, it will take them x number of days.

x =  (25*10)/10*10

x = 2.5 days
