The distance between two towns is 21.673 km. Round of the distance to nearest 0.01 km.
Answer:
21.67
Step-by-step explanation:
look at the number in the 0.01 value then the number next to it
if it's five or above then the 7 goes up if it's 4 and below then the number stays the same. in this case the number will stay the same
On a large baking tray, 40 cookies can be baked together. To bake 40 cookies it takes 14 minutes, for baking 80 cookies it takes 28 minutes, for baking 100 cookies it takes 42 minutes. How much time will it take to bake 140 cookies?
A. 49
B. 56
C. 57
D. 48
Answer:
B. 56
Step-by-step explanation:
1 cookie - 14 minutes
max. 40 cookies
140-100=40
42+14=56
Answer:
56
Step-by-step explanation:
So what you need to do is add the time for 100 cookies (42 minutes) then you need to add the time to make 40 cookies (14 minutes) so then then answer you will get is you answer those is 42 + 14 = 56 (A) minutes to make 140 cookies.

please solve for me it's urgent. A rectangle has 10 and 6cm each. find the area of a square with the same perimeter as that of the rectangle
Answer:
64 cm²
Step-by-step explanation:
Firstly,let us lay down the clues;
So, we have been given the Length and Width of the rectangle.
Rectangle;
Length= 10 cm
Width=6 cm
We know that
Perimeter= 2L + 2W
Perimeter= 10+10+6+6
Perimeter =32 cm
In the questionnaire, it is mentioned that a square has the same perimeter as the rectangle. That means, the perimeter of the square is similar to the one of the rectangle which is 32 cm.
So,
Perimeter of square =32 cm
Length of one side of the square =32÷4
=8 cm
Area= L × W
Area= 8 cm× 8 cm
Area= 64 cm²

Answer:
The answer is 0.3^2 x 10 = the last number to get 0.9
then 0.9^2 = 0.81 x -10 = 8.1 the actual jump = + 1
We go back 1 places before to do missing sum
so that 0.3 x 1 = 0.3 x -9 = -2.7
Therefore the +1 numbers are decreasing from 10 to -10 then increasing in negative value from -10 to -9 etc.

Step-by-step explanation:
The ratio of two numbers is 2:7. the product of these numbers is 224. what is the smaller of these two numbers
Answer:
Step-by-step explanation:
The numbers are 2x and 7x.
2x·7x = 224
14x² = 224
x² = 16
x = ±4
(2x,7x) = (8,28) and (-8,-28)
If you are limited to positive numbers, the smaller number is 8.
If you are not limited, then the smallest number is -28.

Answer:
a. ⅛
b. ⅜
c. -⅜
Step-by-step explanation:
a. From 0 to -1, there are 8 equal segments. So also from 0 to 1, we have 8 equal segments.
Thus, the length of each segment on the number line would be:
1/8 × 1 = ⅛
Each segment has a length of ⅛ on the numberline.
b. From 0 to Point N, there are 3 segments of equal length.
Therefore, point N represents:
3 × ⅛ = ⅜
c. Opposite of point N would be ⅜ from 0 to the left direction.
Thus, opposite of point N = -⅜

Myrna is buying a new rug for her living room. It it spilt into 3 panels, as shown in the diagram. What is the area of the rug, in the square feet?
Answer:
The answer is 96 square feet because if you look at the first rectangle (the one on the top left), you should multiply 5 times 6 which equals 30. (The reason you would do this is because you want to find the area of all of the rectangles first and then add them together in order to get the total area of the rug.) Then, you would look at the second rectangle (the one on the right), and you would multiply 8 times 6 which is 48. Next, you would look at the last rectangle (the one on the lower left) and multiply 6 times 3 which is 18. Finally, you have to add 30+48+18 and then you would get your final answer which is 96 square feet.

Find the value of x for the given value of y. y=5x−7; y=−22
Step-by-step explanation:
we will put -22 in the value of y
-22=5x-7
x will go the left hand side and will shift -22 and 5x
-5x= -7+22
-5x=+15
x=+15/-5
we will simplify it by 5 because both the numbers come in 5 time table
x=+3/-1
x=-3
so the value of x is -3

Which of the following functions represents f(n), the number of small squares in figure n?
A. f(n) = 2n2 + 1
OB. f(n) = (n + 1)2 - 1
OC. f(n) = (n + 1)2 + 1
o D. f(n) = n2 - 1
Answer:
a
Step-by-step explanation:
I dunno how to explain but A is the answer
The solution is, : A. f(n) = (n + 1)^2 – 1, the function represents f(n), the number of small squares in figure n.
Here, we have,
from the given diagram, we get,
the number of small squares in figures are,
Figure 1 is 3,
which be represented as,
3 = 4 - 1
= 2² - 1
= (1 + 1)² - 1
Figure 2 is 8
which be represented as,
8 = 9 - 1
= 3² - 1
= (2 + 1)² - 1
Figure 3 is 15
which be represented as,
15 = 16 - 1
= 4² - 1
= (3 + 1)² - 1
so, we get,
the number of small squares in figure n will be,
The function is:
f(n) = (n + 1)² - 1

If the simple interest on 7000 for 6 years is 2100 then what is the interest rate
Answer:
5%
Step-by-step explanation:
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 7000 × 0.05 × 6 = 2100
I = $ 2,100.00
The simple interest accumulated
on a principal of $ 7,000.00
at a rate of 5% per year
for 6 years is $ 2,100.00.

How do you Decompose 4/10 as the sum of unit fractions?
The fraction 4/10 can be decomposed into smaller fractions as equation
A = 1/10 + 1/10 + 1/10 + 1/10
What is decomposition of fraction?
A fraction can be expressed as the product of a whole number and a unit fraction. Decomposition of fraction means break down a fraction into smaller parts. The denominator which is the bottom number gives the total number of pieces
Given data ,
Let the fraction be represented as A
Now , the value of A is
A = 4/10
The number of parts in the decomposition is given by the denominator
So , denominator of the fraction = 10
And , there are 10 parts in total
So , 4 / 10 can be written as 4 parts of unit fractions of the total 10
The value A can be simplified as
A = 4 x 1/10
On simplifying the equation , we get
A = 1/10 + 1/10 + 1/10 + 1/10
Therefore , the simplified fraction is 4/10
Hence , the decomposed fraction is A = 1/10 + 1/10 + 1/10 + 1/10
