She made 3 sandwiches because 5-2 3/4 = 2 1/4.
2 1/4 as an improper fraction=(4*2)+1=9/4
9/4 / 3/4=3.

List the angles in triangle QRS from smallest to largest.

schepotkina [342]

Answer:

angle R

Step-by-step explanation:

To solve this we will use cosine rule

Cosine rule

cos(A) = $\frac{b^{2}+c^{2}-a^{2}}{2bc}$

suppose,

q = 6.25

s = 11.04

r = 13.19

angleQ = $cos^{-1}(\frac{13.19^{2}+11.04^{2}-6.52^{2}}{2(13.19)(11.04)})$

= 30.58

angleR = $cos^{-1}(\frac{6.52^{2}+11.04^{2}-13.19^{2}}{2(6.52)(11.04)})$

= 93.82

angleS = $cos^{-1}(\frac{6.52^{2}+13.19^{2}-11.04^{2}}{2(6.52)(13.19)})$

= 56.63

Is (0,0) a solution to this system?

Anuta_ua [19.1K]

Answer:

option-B

Step-by-step explanation:

we are given system of inequality as

$y\leq x^2-4$

$y>2x-1$

now, we can check solution

At (0,0):

we can plug x=0 and y=0

and check inequality

$0\leq 0^2-4$

$0\leq -4$

so, this is FALSE

now, we can check second inequality

$0>2\times 0-1$

$0>-1$

So, this is TRUE

so, option-B

Can someone please explain this to me I’m so confused and I have a quiz on this tomorrow

                               x^2 = 16/100
We must solve for x by taking the square root of both sides.
But imagine x^2 = 9. x = 3 is a solution because 3^2 = 9. But x = -3 is also a solution because (-3)^2 = 9. So we need to add the plus and minus sign to account for all of our solutions.
                     √x^2 = √(16/100)
We square root both sides to remove the exponent 2 on x. Then
                         x = ±√(16/100)
Then we have to use a Property of Radicals which is √(x/y) = √(x) / √(y).
Then the square root of 16 is 4 and the square root of 100 is 10. 4/10 is 2/5 simplified.
