Answer:

40.81125m²

Step-by-step explanation:

Hello!

Step 1: Rectangle

We can find the area of the rectangle by multiplying the base by the height.

Step 2: Area small semicircles

If we add the two semicircles, we can see that it's actually 1 whole circle.

So we can simply find the area of the whole circle.

radius = 1/2 * diameter

Step 3: Large semicircle

Now for the last part, the large semi-circle at the top.

Since it's half a circle, we can manipulate the formula by finding half of it.

Step 4: Total Area

Total area = 10m² + 3.14m² + 9.8125m²

                 = 40.81125m²

Answer:

x = -4

Step-by-step explanation:

-2x - 5 = 3

Add 5 to both sides

-2x - 5 + 5 = 3 + 5

Simplify

-2x = 8

Divide both sides by -2

-2x/-2 = 8/-2

Simplify

x = -4

Answer: No. Collin was wrong.

Step-by-step explanation:

From the question, we are informed that the answer that Collin had on his paper was −13 − (15 + 58) and the correct answer, located in the back of the book, was −13 −15 + 58.

Collin is wrong because he didn't take into cognisance the effect of minus on the bracket. Here, −13 − (15 + 58) will be equal to -13 -15 -18. This is because minus multiplied by plus equals to minus. He shouldn't have put the numbers in the bracket.

Answer:

62.8km/hr

Step-by-step explanation:

Given parameters:

Displacement  = 220km due north

Time taken = 3.5hrs

Unknown:

Velocity in km/hr = ?

Solution:

Velocity is the rate of displacement per unit of time. This physical quantity is a vector which has both magnitude and directional attributes.

 So, mathematically;

           Velocity  = [tex]\frac{displacement}{time taken}[/tex]

Insert the parameters and solve;

          Velocity  = [tex]\frac{220}{3.5}[/tex]   = 62.8km/hr

Answer:

They may not know very much about you and assume things about you based on things they see and perceive that are separate from the grades that you get and/or they think you aren't intelligent on something to do with your emotions/behavior and/or someone or some amount of people have developed something against you, these are just potential situations.

Answer:

y = -4/5x + 3

Step-by-step explanation:

Chose any two points on the line:

(5, -2)

(-5, 6)

Slope = (y2 - y1) / (x2 - x1)

6 -(-2) / -5 - 5

8 / -10

-4/5

Equation:

y = mx + b

Plug in x and y using any coords and then plug in m (the slope):

-2 = -4/5 * 5 + b

-2 = -20/4 + b

-2 = -5 + b

Add 5 on both sides:

3 = b

Now our equation is:

y = -4/5x + 3

Answer:

22.50

Step-by-step explanation:

Hat = $18

Austin - 6 letters

0.75 x 6 = 4.5

Letters cost $4.50

18 + 4.5 = 22.5

He'll have to pay 22.50 dollars.

Hope this helps!

Answer:

It costed $1200

Step-by-step explanation:

First Month Saved 1/3 of total cost

Second Month (1/3 of total cost) - 125

Third Month 525

525-125= 1/3 of total (If she saved the same amount the second month as the first month, then she's already saved 2/3 of the money)

400 = 1/3 of total cost

3X400=1200

Set _2__ is a _4__ of set __6_.”

Answer:

A 13°

Step-by-step explanation:

We need to know the measure of angle LMN.

The angle measures of a triangle add up to 180°.

MLN=15°

LNM=180-28=152° (LNM and MNP are supplementary, meaning they add up to 180°)

LMN=15+152=167 180-167=13

Answer:

albert 2500:3000 mark/÷100

25÷30 /÷5

5:6

their ratio is 5:6

Answer:

106 degrees

Step-by-step explanation:

1. Supplementary angles add up to 180.  So subtract 74 from 180 to find the measure of angle C.

2. The full square isn't visible to answer.

1. m∠C = 106°

If angle A and angle C are supplementary, then the sum of their measures is 180°. Thus:

m∠A + m∠C = 180°

74° + m∠C = 180°

m∠C = 180° - 74°

m∠C = 106°

sorry number 1 lang asan kase yung figure sa number 2

It can be deduced that the triangles are similar because the three internal angles are equal for both triangles.

It should be noted that the triangles are similar because the three internal angles are equal.

In this case, the ratio of the corresponding sides are equal and the corresponding angles are congruent.
