What is the measure of angle ECD?

a 79
b 90
c 9
d 17

Answers

Answer:

(A) 79º

Step-by-step explanation:

We can set up a simple equation to solve this, by using supplementary angles and the information that the problem has given:

x - 8 + 90 + 4x + 3 = 180

Now, we can solve:

x - 8 + 4x + 3 = 90

x -  5 + 4x = 90

5x = 95

x = 19

Since we found x, we can now substitute it into the equation of angle ECD:

4(19) + 3 = 79 = m<ECD (A)

Hope this helps!!

Answers

Haileys work is correct so B should be the right answer

Answer:

Hailey's Work

Step-by-step explanation:

Hailey's work is the correct option for this one because:

- The statement specifies that we need to find the quotient of a number and 7, in that order, and Hailey has written it like this: n/7, making the statement valid.

- Quotient represents division, you will need to divide n by 7 in order to get the quotient.

At an amusement park you get five points for each bull’s eye you hit, but you loose 10 points for every miss. After 30 tries, Yolanda lost 90 points. How many bull’s eyes did she hit?

Answers

she hit 21 bull’s eyes.

Answer:

21

Step-by-step explanation:

14 bull's eyes (or hits) and 16 misses.  

The 14 hits earned her five points each, or a total of 70 points.  

The 16 misses cost ten points each, or a total of 160 points lost.  

14 + 16 = 30  

70 - 160 = -90  

SOLUTION:  

points = 5H - 10M = -90 where H = hits and M = misses  

tries = H + M = 30 therefore  

H = 30 - M  

and 5(30 - M) - 10M = -90  

150 - 5M -10M + 90 = 0  

240 -15M = 0  

15M = 240  

M =16  

H = (30 - M) = 16

Complete the ratio table.

An expression is shown below:
2x3 + 10x2 − 4x2y − 20xy

Part A: Rewrite the expression so the GCF is factored completely.

Answers

The answer is 52 I hope this helps you

The given expression can be rewritten as 2x(x²+5x-xy-10y).

The given expression is 2x³+10x²-2x²y-20xy.

What is GCF?

GCF stands for the greatest common factor. The greatest common factor of two numbers is the greatest number that is a factor of both of them.

Now, 2x³=2×x×x×x, 10x²=2×5×x×x, 2x²y=2×x×x×y and 20xy=2×x×x×y

Here, the GCF of all the terms is 2x.

So, the expression becomes 2x(x²+5x-xy-10y).

Therefore, the given expression can be rewritten as 2x(x²+5x-xy-10y).

Answers

Answer:

8.1x^4 x 0.2 = 1.62x^4

Step-by-step explanation:

The estimated multiplication of 8.1 and 4.2 is close to 32.

What is a decimal?

A decimal is represented by a dot that separates the whole part and the fractional part of a number. Decimals can also be converted into fractions and vice versa.

Estimations are essential when we don't have a tool to calculate the exact value of something.

Given A multiplication of two decimal numbers 8.1 and 4.2.

Now 8.1 can be estimated as 8 and 4.2 can be estimated as 4 and we know 8 times 4 is 32 so, the multiplication of 8.1 and 4.2 is close to 32.

Line a and b are parallel lines cut by a transverse line which make angle x and y alternate exterior angles. This means that angle x and angle y have the same measurement value.

The square root of 4 is 2; so twice 2 is 4. Then three added to 4 is 7. So x is equal to 7 and thus y is also equal to 7.

An article in The Globe and Mail, February 16, 2002, reported that IBM used the $300 million proceeds of a sale of one of its business units to reduce operating expenses in its fourth quarter 2001 income statement. This added about 8 cents per share to its fourth quarter earnings. As a result, IBM beat analysts' forecasts by 1 cent per share.IBM defended its treatment by claiming that buying and selling businesses is a normal business practice, and that most of the sale proceeds related to intellectual property that it had developed. The article quotes a Merrill Lynch analyst as saying, "Our only concern is that the company could have done more to call out the magnitude of the transaction." According to the article, IBM's share price fell by 4% as a result of this news.While not mentioned in this article, the SEC opened a preliminary inquiry into IBM's accounting practice, expressing concerns that IBM had let it be known that the reason for its higher operating earnings was tight cost controls, rather than the sale proceeds. This inquiry was subsequently dropped, but the SEC issued a bulletin reminding firms to report gains or losses on asset sales separately from operating costs.RequiredExplain why IBM's share price dropped following the Merrill Lynch analyst's comment and the news of the SEC's preliminary inquiry.
