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:

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:

Step-by-step explanation:

Step-by-step explanation:

so, we had

4+3+2+2+6 = 17 experiments

I assume the spinner has 5 equality sized fields with different colors.

so, normally we would assume that in average each color has the same probability : 1/5 (desired results over totally possible results).

the experiments with the actual spinner give us now observational data and probabilities.

after all, a spinner (as a die, or a roulette wheel, or ...) can have slightly different probabilities for the individual outcomes based on design and manufacturing.

so, based on these results we see the actual probabilities like this

red 4/17

blue 3/17

green 2/17

yellow 2/17

purple 6/17

so, the observed probability shows us a probability of blue in the next spin to be 3/17.

please note, that after that next (18th) spin all the observed probabilities have to be updated depending on the actual result.

so, if the result of spin 18 is indeed blue, the probabilities for spin 19 would change to

red 4/18

blue 4/18

green 2/18

yellow 2/18

purple 6/18

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

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

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°

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:

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

The factors of the given expression [tex]144-49x^{2}[/tex] will be  [tex](7x+12)(7x-12)[/tex]

It is given that

[tex]144-49x^{2}[/tex]

Now by simplifying it

[tex](12)^{2} -(7x)^{2}[/tex]

Now from the formula, we know

[tex]a^{2} -b^{2} = (a+b)(a-b)[/tex]

So it will become

[tex](12)^{2} -(7x)^{2}= (12-7x)(12+7x)[/tex]

Thus the factors of the given expression [tex]144-49x^{2}[/tex] will be (7x+12)(7x-12)
