<u>Answer</u>:

The side length of the square frame is 5.5 inches approximately.

Step-by-step explanation:

Given:

Area of the square frame bought by Miranda= 30 square inches

To find:

Side length of the frame=?

Solution:

we know that,

\text{{Area of a square}} = \text{( side length )}}^2

Here, area of square = 30 square inches .

\text{( side length )}}^2 = 30 square inches

Side length =\sqrt30 inches

Side length = 5.4772 inches

Area of a square equals side squared

(A = s²)

30 = s²

√30 = s

You can use a calculator to find out that √30 ≈ 5.48

or you can use estimation (√25 < √30 < √36) which means that √30 is between 5 and 6.

A group of farmers had to plough 112 acres of land per day. Exceeding the schedule by 8 acres per day, the farmers finished plow
mihalych1998 [28]

The farmers had to plough a total of 1,456 acres of land.

Step-by-step explanation:

Step 1; The group of farmers ploughed at a rate of 112 acres of land a day which was 8 acres more than schedule.

Scheduled rate = 112 acres per day - 8 acres = 104 acres per day.

So the farmers were supposed to plough 104 acres a day according to schedule.

Step 2; If the farmers finished a day earlier, it means they had to have completed ploughing 104 acres extra by doing an extra 8 acres a day.

So days took to complete ploughing = \frac{104}{8} = 13 days.

So in 13 days, they should have ploughed 13 × 104 = 1,352 acres but due to their increased rate, they ploughed 13 × 112 = 1,456 acres in 13 days.

Difference in acres ploughed = 1,456 - 1,352 = 104 acres.

So the farmers ploughed 1,456 acres in 13 days.

Ndicate in standard form the equation of the line through the given points. P(0, -4), Q(5, 1)
tatuchka [14]

Answer:

y=x-4

Step-by-step explanation:

Standard form is y=mx+b

the coordinates (0, -4) tell you that the y intercept is at -4 which means b will be -4. To find slope you have to find the change in y over the change is x. 1--4=5 and 5-0=5. 5/5 is 1 so the slope, or m, is 1. x stays the same since it's the variable. it'll become y=1x-4 and since you don't have to place a coordinate of one in front of a variable, you can just write it as y=x-4
