Answer:

b. $\displaystyle x ≈ 9,9, y = 7$

Step-by-step explanation:

In a 45°-45°-90° triangle, both legs are congruent $\displaystyle [x],$ whereas the hypotenuse is represented by $\displaystyle x\sqrt{2}.$ So, evaluate:

$\displaystyle hypotenuse \hookleftarrow x\sqrt{2} \\ \\ 9,8994949366... = \boxed{7\sqrt{2}}$

Therefore, you have this:

$\displaystyle 9,9 ≈ x$

Can you very be kind and answer

area of a circle is PI x r^2

2 = d/2 = 5.4/2 = 2.7 cm

using 3.14 for PI

3.14 x 2.7^2 = 22.89 square inches

360 degree in a circle, shaded area is 180 degree, which is 50%

so 22.89 x .5 = 11.45 cm^2

Need help with my work pleasem

Galina-37 [17]

Let me start with the second screenshot :-
To find the scale factor you have to enlarge/ dilate A to get B you have a given side so assume that all sides are dilated to the same extent
: . $1 \frac{1}{2} / \frac{3}{4} = 2
$

Thus one can say m would be
$\frac{1}{2} * 2 = 1$

And N would be
$\frac{5}{6} * 2 = \frac{10}{6}$

jason has 150 cents nickels and quarters. if the number of nickels he has is 5 less than the twice the number of quarters, how m

eimsori [14]

Let's set up some simultaneous equations. Let the number of nickels be n, and the number of quarters be q. Now I'm from England so I had to look up the value of a nickel (I could guess the quarter though to be 25c), but apparently it's 5c

Okay we know that the total value of the coins is 150. This gives:

25q + 5n = 150

Rearranging to make n the subject:

n = 30 - 5q

Next, we use the second statement:

n = 2q - 5

Substituting this into the first equation:

2q - 5 = 30 - 5q
7q = 35
q = 5

Putting this value for q into the first equation:

n = 30 - 5(5) = 5

Hence he has 5 of each coin. I hope this helps :)
