Yesterday, Annie walked 9/10 mile to her friends house. Together, they walked 1/3 mile to the library. Which is the best estimate for how far Annie walked yesterday?

Answers

Answer 1

Answer:

Answer:

Total distance traveled by annie is $(37)/(30)$ mile.

Step-by-step explanation:

Distance covered by annie to her friend's house is

$(9)/(10)$ mile.

After there , annie and her friend travelled $(1)/(3)$ mile to the library.

We have to find the total distance covered by annie which can be find by adding total distance traveled by her,

Total distance traveled by annie = distance traveled to friend's house + distance traveled to library.

= $(9)/(10)+(1)/(3)$

Solving it further, we get

= $(27+10)/(30)$

= $(37)/(30)$

Thus, Total distance traveled by annie is $(37)/(30)$ mile.

Answer 2

Answer: 0.9 + 0.333 = 1.233 miles
so about 1 1/2 miles or 1 1/4

What is the slope of the line represented by the equation –5x+2y= 10–5x+2y= 10 ?A)–5/2

B)–2/5

C)2/5

D)5/2

Answers

The slope of the line represented by the given equation is: A. $(5)/(2)$

Given the following equation:

$-5x+2y=10$ ....equation 1

To find t:

The standard form of an equation of line is given by the following formula;

$y = mx + b$ .....equation 2.

Where:

x and y are the points.

m is the slope.

b is the intercept.

From equation 1:

$-5x+2y=10\n\n2y = 5x + 10\n\ny = (5)/(2)x + 10$

Comparing eqn 1 and eqn 2:

Slope = $(5)/(2)$

Think you accidentally typed -5x + 2y = 10 twice.

Anyhow, let's rearrange the equation to match the equation for a line which is y = mx + b:

-5x + 2y = 10

2y = 5x + 10

y = 5/2x + 5

Now, the slope in a line is the m value. So 5/2 is the slope.

y = 5/2x + 5

What is the approximate area of a circle with a radius of 13cm? A.40.8cm² B.530.7cm² C.784cm² D.2461.8cm²

Answers

It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths

the area of a circle can be found by the formula A=pi*r^2. Pi equals 3.14 so multiply that by 13^2. 13^2 equals 169. So 3.14 * 169 = 530.66 cm^2 and that rounded is B) 530.7cm^2

Answers

23, it has to be less than 24 since 25, 26, and 30 are greater than 24.

The greatest possible value is 24. It's not more than 24 and 24 will still be in the middle :)

Bonita said that the product of 5/6 × 1 2/3 is 7/3.How can you tell that her answer is wrong?

A-The answer must be less than 5/6.
B-The answer cannot be an improper fraction.
C-5/6 of a number cannot be greater than the number.
D-The denominator cannot be the same as one of the factors.

Answers

Answer:

The answer is 25/18, not 7/3.

Step-by-step explanation:

1 2/3=5/3

5/6*5/3=25/18

Answer:

C-5/6 of a number cannot be greater than the number.

Step-by-step explanation:

5/6 × 1 2/3 is 7/3.

First let's solve it:

Convert 1 2/3 to an improper fraction

1 2/3 = (1 *3) + 2 / 3 = 5/3

Multiply the fractions

5/6 × 5/3 = 25/18

A is wrong because the answer is not less than 5.6

B is wrong because the answer is an improper fraction.

D is wrong because the denominator is the same as one of the factors.

Therefore it has to be C.

2/3 * 1 = 2/3

Therefore how can 5/6, which is less than 1, multiply by 2/3 and get a greater answer.
