Eli evaluated 23 ÷ 38 and got an answer of 179. Which statement about his answer is true? CLEAR CHECK It is incorrect because th
Arturiano [62]

Staement 1 and statement 4 are true

Staement 1: It is incorrect because thirds and eighths cannot be divided to make ninths

Statement 4: It is incorrect because a quotient cannot be greater than the number that is divided.

<h3><u>Solution:</u></h3>

Given that, Eli evaluated 23 ÷ 38 and got an answer of 179.

Now, let us check the given statements

1) It is incorrect because thirds and eighths cannot be divided to make ninths

It seems right because when 3 is divided by 8, it will give an fractional value. So this statement is correct

2) It is correct because 38 of 23 is 179

It is wrong as 38 x 23 ≠ 179 and not even related to the question.

3) It is correct because 179 • 38 equals 23

It is wrong because 179 x 38 ≠ 23

4) It is incorrect because a quotient cannot be greater than the number that is divided.

It is right as the dividend can not be smaller than the quotient.

Hence, the 1st and 4th statements are right.

What are the solutions to the quadratic equation below?
Luden [163]

Using factorization method;

x²+13x+40=0

x²+13+40

Find two numbers that you can add together to give the co-efficient of variable x. (I.e 13 for this question). Also, you'll find two numbers that you can multiply with each other to give you the whole number as an answer. (I.e 40 in this question). The two numbers must be the same (i.e the two numbers that will be added to give the co-efficient of x and the two numbers that will be multiplied to give the whole number must be the same two).

The two numbers are +5 and +8

The equation will therefore be = x²+5x+8x+40

You'll then factorize (I.e use a common factor of both values to bracket them)

x(x+5)+8(x+5)

(x+8)(x+5)

x is therefore (x+8=0) or (x+5=0)

x=(x=0-8) or (x=0-5)

x= -8 or x= -5

  hurry please! 20 points. Find the measure of angle θ. Round your answer to the nearest tenth place.
ElenaW [278]

Answer:

Angle θ would be about 17.1 degrees.

Step-by-step explanation:

To figure out what Angle θ is, first we have to find the hypotenuse. You can easily do that by find the square root of BC² + AC².

c = √4² + 13²

Square 4 and 13 to get 16 and 169 respectively.

c = √16 + 169

Add 16 and 169 to get 185.

c = √185

Find the square root of 185 (I'll round to the nearest tenth.)

c = 13.60147 ≈ 13.6 units

To find angle β, divide AC by AB and find the inverse sine of that.

β = arcsin(13/13.6)

Divide 13 by 13.6. Round to the nearest thousandth.

β = arcsin(0.955)

β ≈ 1.2723 rad

To convert radians to degrees, multiply the radians by 57.2957795 for an approximate amount.

β ≈ (1.2723 * 57.2957795)°

β ≈ 72.8974203 ≈ 72.9 degrees

Now subtract 72.9 from 90 to get angle θ's measure of 17.1 degrees.

Toenails grow at an average rate of about 0.05 mm per day, and the average toenail is about 3/4 inch long. About how many months
nirvana33 [79]
0.05 mm * ? days = 0.75 inch

Use proportions

1 mm = 0.0394 inch
0.05 mm = 0.00197 inch

0.75 inch / 0.00197 inch = 380.71

380.71 days / 30 days = 12.7 months
