How do you round 8.876 to the nearest whole number?

1 answer:

8 0

8.876 to the nearest whole number
8.876 can be rounded to 9 because if we have a number greater than 5 we round to next number i.e is 9 but if we have a number smaller than 5 then we round to the previous number that is 8.

So your answer is 9

3. Could a 5 x 8 matrix have dim Col A 6 and dim Nul A - 2? Justify your answer. (Hint: Think about the possible pivot rows and

alexdok [17]

Answer:

Step-by-step explanation:

A 5x8 matrix $A$ represents a linear transformation between the vector space $\mathbb{R}^8$ and $\mathbb{R}^5$ . Remeber that the columns of $A$ generate the image of the linear transformation, which is a vector subspace of $\mathbb{R}^5$ . Therefore, $\dim \text{Col}A \leq 5$ , which is the dimension of the the total space.

A 30-m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 32 m. Find the length

zepelin [54]

Answer: 11.1 m

Step-by-step explanation:

This can be solved by the Pythagorean theorem where;

c² = a² + b²

c is the hypotenuse which is the distance from the top of the building to the tip of the shadow.

a is the height

c is the length

32² = 30² + b²

b² = 32² - 30²

b² = 1,024 - 900

b² = 124

b = √124

b = 11.1 m

Add the fractions and simplify the answer 1/2 +2 /3

IrinaVladis [17]

What we are going to do is add $\frac{1}{2}$ by $\frac{2}{3}$ . The first thing we do is make common denominators for $\frac{1}{2}$ and $\frac{2}{3}$ : $\frac{1*3}{2*3}= \frac{3}{6} \ and \ \frac{2*2}{3*2}= \frac{4}{6}$ . Now we add $\frac{3}{6}$ by $\frac{4}{6}$ : $\frac{3}{6}+ \frac{4}{6}= \frac{7}{6}$ . Now we make $\frac{7}{6}$ a mixed number: $\frac{7}{6}=1 \frac{1}{6}$ . Therefore, your answer is $\boxed{\boxed{1 \frac{1}{6}}}$ . Hoped I helped. :)
