Answer:
Hot dog:155 calories Cottage cheese: 200 calories
Step-by-step explanation:
Make 2 equations ---->(y=cottage cheese, x=hot dog) 2x+3y=910, 5x+2y=1,175---> solve for one variable---> x+1.5y=910---> x=605-1.5 y-----> do for both-----> x=155, y=200
A)2.8
b1) 4.5/2.8
b2)impossible because if you want to do trigonometry you can't have that is an angle (Which is 148.1) larger than 90 degrees.
but if its angle BAF then the angle would be 2.8/5.3
c)41.32
To put an equation into (x+c)^2, we need to see if the trinomial is a perfect square.
General form of a trinomial: ax^2+bx+c
If c is a perfect square, for example (1)^2=1, 2^2=4, that's a good indicator that it's a perfect square trinomial.
Here, it is, because 1 is a perfect square.
To ensure that it's a perfect square trinomial, let's look at b, which in this case is 2.
It has to be double what c is.
2 is the double of 1, therefore this is a perfect square trinomial.
Knowing this, we can easily put it into the form (x+c)^2.
And the answer is: (x+1)^2.
To do it the long way:
x^2+2x+1
Find 2 numbers that add to 2 and multiply to 1.
They are both 1.
x^2+x+x+1
x(x+1)+1(x+1)
Gather like terms
(x+1)(x+1)
or (x+1)^2.
Answer:
68°
Step-by-step explanation:
Okay, so m<8 is on the same plane as m<7 because line <em>q </em>is intersecting line <em>t </em>and that's supposed to add up to 180° so:
180° - 112° = 68°
So, m<7 = 68°
hope this helps:)
Answer:
−7b−9k+6
Step-by-step explanation:
−4b+(−3b)=−7b
+(−9k)=−9k
12−6=6
