Answers

Answer:

100:350                   simplified: [tex]\frac{2}{7}[/tex]

Step-by-step explanation

A ratio of 2:3 means that for every item of A, we can expect of item B. Therefore, our total group is 2+3=5.

Calculate expected number of item A:

[tex]\frac{2x500}{5}[/tex]

Expected number of item A: [tex]\frac{1000}{5}[/tex]

This fraction can be reduced by 5 giving you:

Expected number of item A: 200

Calculate expected number of item B:

[tex]\frac{3x500}{5}[/tex]

Expected number of item B: [tex]\frac{1500}{5}[/tex]

This fraction can be reduced by 5 giving you:

Expected number of item B: 300

I need to find the value of x and the measure of the exterior angle

Answers

Given:

In a right angle triangle, the measure of exterior angle is [tex](9x+16)^\circ[/tex].

The measure of opposite interior angle is [tex](5x-14)^\circ[/tex].

To find:

The value of x.

Solution:

Exterior angle theorem: In a triangle the measure of an exterior angle is equal to the measure of sum of two interior angles.

Using exterior angle theorem, we get

[tex](9x+16)^\circ=90^\circ+(5x-14)^\circ[/tex]

[tex](9x+16)^\circ=(5x+76)^\circ[/tex]

[tex]9x+16=5x+76[/tex]

Isolate the variable x.

[tex]9x-5x=-16+76[/tex]

[tex]4x=60[/tex]

[tex]x=\dfrac{60}{4}[/tex]

[tex]x=15[/tex]

The value of x is 15. So, the measure of the exterior angle is:

[tex](9x+16)^\circ=(9(15)+16)^\circ[/tex]

[tex](9x+16)^\circ=(135+16)^\circ[/tex]

[tex](9x+16)^\circ=151^\circ[/tex]

Therefore, the value of x is 15 and the measure of the exterior angle is 151 degrees.

(y − 5)

Answers

Answer:

(y - 8)

Step-by-step explanation:

If you factor the original expression, y^2 - 10y + 16, you get (y-2)(y-8) so (y-8) is the other factor. You could also test this by multiplying (y-2)(y-8) together and seeing if you get the original expression.

If Nate was growing 1.68 inches permonth, how much will he grow in 6 1/2 months?


Plz help what do I have to do to get the answer?? What’s the answer

Answers

Answer:

10.92 inches

Step-by-step explanation:

So Nate grows 1.68 inches a month in this case you have 6 and a half month which is equivalent to 6.5 and so in this case you can multiply.

1.68 inches*6.5 months = 10.92 inches

Answer:

10.92 inches

Step-by-step explanation:

Use a proportion. Set up two ratios equal to each other.

Given ratio:

The ratio of months to inches of growth is

1 month : 1.68 inches or 1/1.68

Now set up a ratio involving the unknown amount.

6 1/2 is the same as 6.5

In 6.5 months, he grows x inches.

6.5 months : x inches, or 6.5/x

Set the ratios equal creating a proportion.

[tex] \dfrac{1}{1.68} = \dfrac{6.5}{x} [/tex]

Cross multiply.

1 * x = 1.68 * 6.5

x = 10.92

Answer: 10.92 inches

The sum of the measures of the angles of a quadrilateral is 360 degress. Quadrilateral JKLM has one right angle. Use the angles relationships and measure given below to find the measure of angle k

Answers

Answer:

Measure Of Angle K is 82*

Step-by-step explanation:

According To Question, We Have Given

A Quadrilateral JKLM, We Know Sum Of All The Angles Of Quadrilateral Is 360* .

Thus

∠JKL=90*

∠KLM= 180* - 110* = 70* ( Find Diagram In Attachment )

∠MJK=118* (Alternative Opposite Angle)

Now We Have To Find The Value Of ∠LKJ.

∠K = 360* - (∠MJK+∠KLM+JKL)

∠K = 360* - (118* + 70* + 90*)

∠K = 360* - 278*

∠K = 82*

how many terms of the A P -6,11/2,-5......are needed to give the sum -25??




plzx give me all the steps....!!​

Answers

I think the second number is supposed to be negative, -11/2 = -5.5, because otherwise the sequence is not arithmetic.

The n-th term of the sequence, starting with n = 1, is then

-6 + 0.5 (n - 1) = 0.5n - 6.5

and we want to find the number N such that

[tex]\displaystyle\sum_{n=1}^N(0.5n-6.5)=-25[/tex]

We have

[tex]\displaystyle\sum_{n=1}^N(0.5n-6.5) = 0.5\sum_{n=1}^Nn-6.5\sum_{n=1}^N1\\ = 0.5\times\frac{N(N+1)}2 - 6.5N \\= 0.25N^2-6.25N = -25[/tex]

Solve for N :

0.25 N ² - 6.25N + 25 = 0

N ² - 25N + 100 = 0

(N - 20) (N - 5) = 0

N = 20   or   N = 5
