Rhea draws rows and columns on a big piece of paper to make 16 same-sized squares. How many rows and columns does she draw? I

Answers

Answer:

4 rows and 4 columns

Step-by-step explanation:

Given

16 same sized squares

Required

Determine the number of rows and columns

Since the shape formed is a square, then the following relationships exist:

[tex]Row * Column = 16[/tex]

[tex]Row = Column[/tex]

[tex]Row * Column = 16[/tex] can then be rewritten as:

[tex]Row * Row = 16[/tex]

[tex]Row^2 = 16[/tex]

Take square roots of both sides

[tex]Row = \sqrt{16[/tex]

[tex]Row = 4[/tex]

[tex]Row = Column[/tex] implies that:

[tex]Row = Column = 4[/tex]

Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds. By what percentage did Mr. Pope decrease he weight?
a. (4%)
b. (7%)
c.(10)
d.(15%)

Answers

The answer for this question would be a which is 4% and hopefully you get it right

Mr. Pope decreased his weight by 4 percent.

What is percentage?

A percentage is a portion of a whole thing written as a number between 0 and 100 instead of fraction.

Given that, Mr. pope lost 10 pounds in one month. At the end of the month, he weighed 240 pounds.

we need to find the percentage of decrease of his weight,

So, basically we will use here the concept of percentage change,

Formula = final amount - initial amount / initial amount x 100

Since, he lost 10 pounds and has 240 pounds so, initially he weighted = 240 + 10 = 250 pounds

So, percentage decreased = -10 / 250 x 100 = -4% [minus is the sign for decrease]

Hence, Mr. Pope decreased his weight by 4 percent.

$4040.57

Step-by-step explanation:

A=P(1+(r/n))^nt

P = Principal = 3000

r = rate = 0.03

n = no. times payed each year = 2

t = years = 10

A = 3000(1 + (0.03/2))^(2x10)

What is the measure of ∠A, the exterior angle of the triangle shown below?


F. m∠A = 92°, because 180 – (50 + 38) = 92.

G. m∠A = 272°, because 180 – (50 + 38) = 92 and 92 + 180 = 272. H.m∠A=78°,because 50–38=12and90–12=78.

J. m∠A = 88°, because 50 + 38 = 88.

Answers

Answer: A is 88

Step-by-step explanation: Sum of all angles is 180 degree.

Let the third interior angle be x.

38+50+x=180

88+x=180

x= 92

A and X are in linear pair.

A+X=180

A+92=180

A=88

Answers

Answer:

The answers are B and E

Step-by-step explanation:

The square root of 4 is 2.

The cube root of 8 is 2.

A is wrong because its value is 4.

C is wrong because its value is 4.

D is wrong because the square root of 8 isn't whole.

Answer:

E. √4

B. ³√8

Step-by-step explanation:

You can find this simply by putting it into a calculator if you have access to one. Just type √ and 4. If you don't have a calculator, you can just use the knowledge that 2 × 2 = 4, hence why it's the square root of 4 :)

You can also determine that B is correct by doing 2 to the power of 3.

2³ = 8, so you know that B is correct too.
