Hello!

When you subtract these numbers, you always first subtract the numbers in the smallest place value. In this case, that would be the .5 and .7. However, since you cannot subtract 7 from 5 without getting a negative number, borrow a one from the place value that is one greater.

Thus, you get:

15 - 7 = 8

Therefore, we know that the ._ digit of our result is .8.

Now, moving on to the next smallest place value (in this case the largest).

You would subtract 7 - 3, however remember earlier that we borrowed a one. When you borrow a one, you must subtract one from the number that it was borrowed from. Therefore, the equation would become 6 - 3.

6 - 3 = 3

Therefore, the ones digit of our result is 3.

Put these two together, and you get your result of 3.8.

Hope this helps!

Answer:

y = 9 $\sqrt{2}$

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = $\frac{1}{\sqrt{2} }$

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{9}{y}$

Multiply both sides by y

y × sin45° = 9, that is

y × $\frac{1}{\sqrt{2} }$ = 9

Multiply both sides by $\sqrt{2}$

y = 9 $\sqrt{2}$

In a game, a player earns 100 points for each question answered correctly and earns -30 points for each question answered incorr

REY [17]

The general expression is 130 x - 600 and total points scored by the player is 1220

A) Let the number of correctly answered questions be x.

∴ Number of incorrectly answered questions will be 20 - x.

+ 100 points is awarded for each question answered correctly while -30 points is awarded for each question answered incorrectly.

Thus, the general equation becomes

= 100x - (20 - x)(-30)

= 100x +30x - 600

= 130x - 600

Thus the general expression becomes 130 x - 600

B) The player answers 14 questions correctly, thus x = 14

Substituting the value of x =14 in the general equation we get,

= 130(14) - 600

= 1820 - 600

= 1220.

Thus the total points scored by the player will be 1220

the area of a rectangle is text square and the length of the rectangle is 3 ft more than twice the width. find the dimensions of

Aneli [31]

Area of rectangle = 35 feet square
Let the Width of rectangle is x feet.
Length of rectangle is 3 feet more than twice the width.
Thus,Length can be written as: 2x + 3

Area of rectangle is product of its length and width.
So,

Area = Length x Width

$35 = x (2x + 3) \\ \\ 
35 = 2 x^{2} +3x \\ \\ 
2 x^{2} + 3x - 35 = 0 \\ \\ 
2 x^{2} + 10x - 7x - 35 =0 \\ \\ 
2x (x + 5) - 7 (x+5) = 0 \\ \\ 
(2x-7)(x+5)=0$

Thus
x = -5
or
x =7/2 = 3.5

Since the measure of width cannot be negative, we neglect x = -5. and keep the value x = 3.5

Therefore,
Width = 3.5 feet
Length = 2x + 3 = 2(3.5) + 3 = 10 feet
