Step-by-step explanation:

Tara has two bags of marbles. The first bag contains 6 red marbles, 5 blue marbles, and 4 green marbles. The second bag contains 3 red marbles, 2 blue marbles, and 4 green marbles. Tara will randomly select 1 marble from each bag.

What is the probability that Tara will select a blue marble from each bag?

Answers

Answer:

The first bag,  1 in 3 and the second, 2 in 9.

Step-by-step explanation:

If there are 15 total marbles in the first bag, and 5 blue, there is a 5 in 15 chance, or 1 out of 3 chance she could pull a blue out of the first bag. The second bag, has 9 in total and 2 blue, so there is a 2 in 9 chance she could pull out a blue from the second bag. Hope this helps!

factor the expression below 36a2-49b2

Answers

Answer:

(6a - 7b)(6a + 7b)

Step-by-step explanation:

Given

36a² - 49b² ← this is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Thus

36a² - 49b²

= (6a)² - (7b)²

= (6a - 7b)(6a + 7b)

Can someone please how to do fractions in the lowest terms

Answers

Answer:

In order to out a fraction in lowest terms, you must divide by the Greatest Common Factor, or GCM, of the numerator and denominator in the fraction. Let's say we have the fraction 25/100. We know that the greastest common factor of 25 and 100 is 25, as 25 ÷ 25 = 1 and 100 ÷ 25 = 4 so 25/100 in lowest terms is 1/4:

25        25       1

___  ÷ ___ = ___

100      25       4

If the GCM of a fraction equals 1, the fraction is simplified. Because the only common factor of 1 and 4 is 1, we know this fraction is simplified.

1        1         1

__ ÷ ___ = ___

4        1        4

Answers

Answer:

100 because you cal look at the balz on that

Step-by-step explanation:

The measure of exterior angle ∠CAD of a triangle ABC is 100°.

From the given figure, ∠ACB=80° and ∠ABC=20°.

What is an exterior angle theorem?

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two remote interior angles of the triangle.

From the given triangle,

m∠CAD=m∠ACB+m∠ABC

⇒ m∠CAD=80°+20°

⇒ m∠CAD=100°

Therefore, the measure of exterior angle ∠CAD of a triangle ABC is 100°.

work out the equation of a line which has a gradient of -2 and passes through the point (1 ,7)​

Answers

Answer:

Y=-2x+9

Step-by-step explanation:

The first thing is to know the formula which is Y÷x

Then... The line (1,7)use the coordinates Y and X so it will be as follows... Label 1 and 7 as x, y

So it will be Y-7÷X-1 = the gradient which is - 2

So multiply both sides by X-1

So it will be Y-7=2x+2 again be careful because a negative number multiplied by another negative will give you a positive sign

Remember Y-7....... Take 7 to the other side so it will be a positive...... Then work out the integers

2x + 4y-31=123 what is the equation for x and then y​

2x +4y = 154

4y = 154 -2x

y = ( 154 - 2x ) / 4

Kerry is looking foward to a skiing trip this weekend she checked the tempature yesterday and today, and overnigjt is dropped from 12 F to -5 F what is the total difference in the tempature

Answers

Answer:

-[tex]17^\circ F[/tex]

OR

[tex]17^\circ F[/tex] decrease in the temperature.

Step-by-step explanation:

Given that:

Temperature at the night  = [tex]12^\circ F[/tex]

Temperature in the morning = -[tex]5^\circ F[/tex]

To find:

The total difference in the temperature = ?

Solution:

Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.

Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]

Negative value in the difference indicates that there is a decrease of the quantity.

So, the answer is:

Andrea has a balance of $135.68 in her savings account. Every Friday Andrea goes to the bank to deposit $170.50 and withdraw (take out) $60. If she does this every Friday for 4 weeks, how much money does Andrea have in the bank? Show all work or explain how you got your answer.

Answers

Answer

577.68

Step-by-step explanation:

first you subtract 60 from 170.50 to get 110.5. After that you multiply by 4 to get 442. take 442 and add it to 135.68 to get 577.68. so it would look like this

170.500-60=110.5 110.5 x 4=442  442+135.68=577.68

Step-by-step explanation:

Find the measure of each numbered angle

Answers

measure of angle 1 is 56
measure of angle 2 is 56
measure of angle 3 is 74

All triangle’s angles add up to 180

The measure of each numbered angles are ∠1 =  56°, ∠2 = 56° and ∠3 = 74°.

What is Angle?

An angle for any figure is formed by two rays which joins at a common point called vertex or node.

Usually angles are measured in degrees or radians.

Consider triangle PMQ

The sum of the interior angles of a triangle is 180°.

∠MPQ + ∠QMP + ∠PQM = 180°

58° + 66° + ∠1 = 180°

∠1 =  180° - (58° + 66°)

∠1 =  180° - 124°

∠1 =  56°

Now, ∠1 and ∠2 are vertically opposite angles. Hence they are equal.

∠2 = 56°.

Again, for triangle NQO

∠2 + ∠3 + 50° = 180°

56° + ∠3 + 50° = 180°

∠3 = 180° - (50° + 56°)

∠3 = 180° - 106°

∠3 = 74°

Hence ∠1, ∠2 and ∠3 are 56°, 56° and 74° respectively.
