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

Answer:

x = 6.73

Step-by-step explanation:

tan17 = x / 22

x = 22 * tan17

x = 6.73

sin17 = 0.2924

cos17 = 0.9563

tan17 = 0.3057

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

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.

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.

Answer:

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

#SPJ2

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

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.

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.

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.

Step-by-step explanation:

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
