Answer:  c. 352.50 cm²

Step-by-step explanation:

Looking at the shape one can see that it is made up of 3 rectangles and 2 triangles.

The surface area will therefore be the sum of the areas of these 5 shapes.

Rectangle area = Length * width

= 7.5 * 13.5

= 101.25 cm²

There are 3 of them:

= 101.25 * 3

= 303.75 cm²

Triangles = 1/2 * base * height

= 1/2 * 7.5 * 6.5

= 24.375 cm ²

There are two of them:

= 24.375 * 2

= 48.75cm²

In total:

= 303.75 + 48.75

= 352.50 cm²

Answer:

c=2a+b/d

Step-by-step explanation:

Multiply both sides by c.

2a+b=cd

Flip the equation.

cd=2a+b

Divide both sides by d.

cd/d = 2a+b/d

Answer:

the answer is B

Answer:

2

Step-by-step explanation:

Number 2 was written wrong because it should have been 1 inch / 2.54 centimeters, not the other way around.

This is because the units of the number on the top of the previous one (in this case, centimeters) has to be the same as the units on the bottom of the fraction. This means that if you have cm on top of one, the next one has to have cm on the bottom of the fraction.

Answer:

x=0

Step-by-step explanation:

Answer:

The value of x is 29.

Step-by-step explanation:

→ The angles arent congruent, they are supplementary.

→ Supplementary angles equals 180 degrees.

→ The equation looks look:

[tex]2x - 10 + 4x + 16 = 180[/tex]

→ Let's solve the equation.

[tex]2x - 10 + 4x + 16 = 180 \\ 6x + 6 = 180 \\ \frac{ \: \: \: \: \: - 6 = - 6}{ \frac{6x}{6} = \frac{174}{6} } \\ x = 29[/tex]

→ Therefore, the value of x is 29.

Answer:

The fisherman row 6.4 miles total.

Step-by-step explanation:

Let the distance from his starting point to the  point he turn around is "d" miles.

Given  upstream speed is 2 mph and downstream speed is 8 mph.

We now that  time  =  distance /speed

So  the time required to row "d "miles upstream = d/2 hours

   The time required to row "d" miles downstream  = d/8 hours.

As the entire trip  took  2 hours  so the equation will be :

  d/2 +d/8  =  2

  ( 4d + d ) /8 =   2

  5d  =  16

  d  =   16/ 5 = 3.2 miles

So the fisherman rowed a total of  ( 3.2 x 2 ) miles =  6.4 miles.

Answer: y = − 3/2 x + 8

Step-by-step explanation:

Find the Perpendicular Line

Solve −2x + 3y = −6.

y = −2 + 2x/3

Find the slope when y = −2 + 2x/3 .

m = 2/3  

The equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.

[tex]m[/tex] perpendicular = [tex]-\frac{1}{\frac{2}{3} }[/tex]

Simplify to find the slope of the perpendicular line.

perpendicular = −3/2

Find the equation of the perpendicular line using the point-slope formula.

y + 1 = − 3/2

⋅ (x − 6)

Write in y = mx + b form.  

y = − 3/2 x + 8

Answer:

[tex]42ft^{2}[/tex]

Step-by-step explanation:

[tex]2\sqrt{7}[/tex] × [tex]3\sqrt{7}[/tex]

Multiply the numbers outside the root and inside the root.

[tex]2x3=6[/tex]      [tex]7x7=49[/tex]

[tex]6\sqrt{49}[/tex]

Simplify whats under the root

[tex]\sqrt{49} = 7[/tex]

[tex]6[/tex]×[tex]7=42[/tex]

Step-by-step explanation:

y = 5x - 4

When x = 0, y = 5(0) - 4 = -4.

When x = 1, y = 5(1) - 4 = 1.

When x = 2, y = 5(2) - 4 = 6.

The 3 ordered pairs we have are (0,-4), (1,1) and (2,6).

We now check the point (-5,-29):

(-29) : 5(-5) - 4

-29 : -25 - 4

-29 : -29 => -29 = -29.

Since Left hand side = Right hand side, the point (-5,-29) is a solution.

Answer:

1. (1,1) (2,6) (3, 11)

2. Yes

Step-by-step explanation:

1. 5(1)-4 = 5-4 = 1

5(2)-4 = 10-4 = 6

5(3)-4 = 15-4 = 11

(I just chose 3 simple x values and plugged them into the equation to get the y values then wrote it as an ordered pair)

2. 5(-5)-4 = -25-4 = -29

-29 = -29

(Same as number 1 but I used the given x value then I checked if the y value I got matched the ordered pair)

Answer:

$7.22 per foot squared

Step-by-step explanation:

hope this helps

Answer:

Step-by-step explanation:

We need the unit rate here. The best way to do this is to write a proportion.

Let x = the $ for 1 ft.

130/18 = x/1

130 = 18x

Divide by 18

x = $7.22

Now, we check to make sure we are correct.

130/18 = 7.22/1

130 = 130 ✅

Answer:

h = 120

Step-by-step explanation:

The required, division of h=(500-260)divided by 2 is 120..

The division is a mathematical operation that involves distributing or sharing a quantity into equal parts. It is the inverse operation of multiplication. In division, a dividend is divided by a divisor to obtain a quotient.

h = (500 - 260) divided by 2

To solve this expression, we first perform the subtraction within the parentheses:

h = (240) / 2

Simplifying further:

h = 120

Therefore, the value of h is 120.

in the rigid class structure of the colonies, native-born Spaniards who held all the important positions in government were known as peninsulares. Those of Spanish descent born in the colonies were called creoles. Poor colonists of mixed race, Spanish and Indian, were called mestizos. At the bottom of the social structure were the indians/native peoples, who were poor and did most of the work.
