Karl has 5 blue pencils, 3 yellow pencils and 2 black pencils. If Karl selects 2 pencils at random from his pencil case, without replacement, what is the probability that both pencils are not yellow?

Answers

In total you have 10 pencils but only 2 of them are yellow. Therefore when simplify this, the changes of not picking a yellow pencil is 8/10 which simplify to 4/5. There’s a 4/5 chance neither pencils will be yellow
The probability is 42/90 simplified to 7/15

Equation: probability of first non-yellow pencil x probability of second non-yellow pencil
7/10*6/9= 42/90= 7/15

There are 7 total pencils that are not yellow but because you don’t put the non-yellow pencil back there is a decrease in both the non-yellows and total pencils!

Answer:

[tex]-x + 9[/tex]

Step-by-step explanation:

Hello!

We want to combine any like terms and distribute the signs properly to the terms in the parentheses.

First, remove the parentheses by distributing the signs:

[tex]-(2x - 1) + 3(x + 4) - 2(x + 2)[/tex][tex]-(2x) - (-1) + 3(x) + 3(4) - 2(x) - 2(2)[/tex]

Remember that negative times negative is positive
[tex]-2x + 1 + 3x + 12 - 2x - 4[/tex][tex]-2x + 3x - 2x + 1 + 12 - 4[/tex][tex]-x + 9[/tex]

The simplified form is [tex]-x + 9[/tex].

Another way to think about the negative sign is by replacing it with -1, so essentially you are multiplying the whole parentheses by -1.

-(2x-1)+3(x+4)-2(x+2)-2x+1+3x+12-2x-4-4x+3x+1+8-x+9

Option D

how much will you have to pay back in total if you borrowed $400 from the bank for a year at 12%

Answers

1) figure out interest amount

400x.12= 48

2) add interest and loan amount

400+48= 448

You would have to pay back $448 in total after one year.

What is the amount on the loan?

The simple interest formula can be expressed as;

I = P × r × t

Where I is interest, P is principal, r is interest rate and t is time.

Given the parameters:

Principal P = $400 (the initial loan amount)

Rate r = 12% = 12/100 = 0.12

Time t = 1 year

Interest = ?

To determine the interest, we can use the above formula for simple interest:

I = P × r × t

Interest = $400 × 0.12 × 1

Interest = $48

Money to be paid back will be:

Amount = Principal + Interest

Amount = $400 + $48

Amount = $448

Therefore, the accrued amount to be paid is $448.

Triangles are congruent due to SAS

Angles are congruent due to CPCTC

Step-by-step explanation:

In order to prove the congruency of the angles, we have to prove the congruency of the triangles.

ME=MR is given so that is a side

They share angle M so that is an angle

And, MA=MN which is given so that is a side.

The two triangles are congruent due to SAS postulate

So the angles are equal due to CPCTC

Angles E and R are congruent as they are the corresponding parts of two congruent triangle.

Given is a figure which shows two connected triangles ΔEMA and ΔRMN,

We need to prove ∠E ≅ ∠R.

Considering the triangles,

ME = MR [given]

MA = MN [given]

∠M is common angle in both triangles,

So, ΔEMA ≅ ΔRMN by SAS postulate.

So, ∠E ≅ ∠R by CPCTC.

Hence proved.

Answer:

[tex]\huge\boxed{\sf x =28 \textdegree}[/tex]

Step-by-step explanation:

Given that,

∠IAK = 62°

∠IAK + ∠IAD = 90° (Complementary angles)

62 + ∠IAD = 90°

Subtract 62 to both sides

∠IAD = 90 - 62

∠IAD = 28°

∠IAD = ∠ACB (Corresponding angles are equal)

So,

∠ACB = 28°

∠ACB = ∠GCJ (Vertically opposite angles are equal)

So,

28° = x°

OR

x° = 28°

[tex]\rule[225]{225}{2}[/tex]

Answer:

28 degrees

Step-by-step explanation:

If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.

--> Angle LAJ is 62 degrees

If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.

We know that in a triangle, there are three angles, and the angle measures combined equals 180.

Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.

--> 180 - 90 - 62 = 28

--> Angle BCA = 28 degrees

Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.

Angle x = 28 degrees

Find the quotient. 5 1/4 - 15

a. 7/20
b. 78 3/4
c. 2 6/7
d. 3 1/4​

Answers

What I find helps me with division is turning fractions into decimals. In this case 5 1/4 becomes 5.25 and 5.25/15 is .35 (equivalent to 7/20) Answer A: 7/20
The answer should be C- 2 6/7

I believe the question you are asking is what 5 1/4 (otherwise known as 5.25) divided into 15 is.

Simply put, your question is 15 divided by 5.25 (or 5 1/4)

To solve this we can make the fraction 5 1/4 into an improper fraction. This makes the fraction to consist of a numerator and a denominator and no whole numbers. Converting 5 wholes into fourths would mean 5 times 4 which is 20. Therefore 5 converted into 1/4 ‘s is 20 1/4’s. This combined with the other 1/4 in the fraction 5 1/4 makes the improper fraction 21/4.

When you divide fractions you switch the numerator and denominator of the fraction on one side (usually the right side although it doesn’t matter as long as you only switch one fraction of the two) and multiply. 15 times now 4/21 is 60/21.

To simplify this you can divide the numerator and denominator by a common factor. We can start with 3, simplifying the fraction to 20/7. Now as you may notice in the answer choices they are all mixed numbers, consisting of a whole number as well as the numerator and denominator. 20/7 as a mixed number is 2 6/7 as you can have 2 times 7 (14) and then have 6 left so you have 2 wholes and 6/7 away from another whole. This makes C the answer
