if a 48-gram serving of pasta contains 6 g of protein how many grams of protein are in a 1,362 gram box of pasta
Answer:
170.25 grams of protein
Step-by-step explanation:
6/48 = p/1362
cross multiply
6 x 1362 = 48p
8172 = 48p
isolate variable (p) with division
8172/48 = p
170.25 = p

Find the slope of the line that passes through (-1, -3) and (-2,2).
Answer:
-5
Step-by-step explanation:
Answer:
slope = -5
Step-by-step explanation:
m = y2-y1/x2-x1 (this is the equation for finding a slope of 2 points)
so plug them into this equation.
2+3/-2+1 = 5/-1 = -5.
the slope is -5

Do the line segments with the given lengths form a right triangle? Drag each set of lengths into the correct box.
Answer:
1) Yes
2)No
3)Yes
Step-by-step explanation:
Use pythagoreans theorem for the first two side lengths and see if it's equal to the third!
Based on the Pythagorean Triple, "9, 40, 41", " will form a right triangle(YES), while "11, 60, 62" and "48, 55, 73" will not (NO).
To find given lengths form a right triangle or not.
What is the Pythagorean Triple?The Pythagorean triple can be described as any three set of integers representing sides of a right triangle that are solutions to the Pythagorean Theorem, which is given as:
c² = a² + b².
c is the longest side of the right triangle or largest of the set of integers of the Pythagorean triple.
Thus, find out which set of lengths will form a right triangle:
9, 40, 41 will form a right triangle, because:
41² = 40² + 9²
1,681 = 1,681
Also, the rest set of lengths will not form a right triangle.
Thus, based on the Pythagorean Triple, "9, 40, 41", " will form a right triangle(YES), while "11, 60, 62" and "48, 55, 73" will not (NO).

The sum of a number and 45 plz need the answe
Answer:
n + 45
Step-by-step explanation:
The question is asking to write an algebraic expression for the sum of a number and 45. We know we are adding a number to 45. So we use addition. But, we don't which number we are adding to 45. So we just use a variable. I used "n", but use whatever letter you want ( x, y, z, etc). I recomend using the same variable that your intrcuctor uses.
Hope this helps.

Can someone please please answer this
Answer:
10°
Step-by-step explanation:
You can see the three angles shown form a straight line, meaning they add up to 180°. We can et up the equation:
m<AOC + m<COD + m<DOB = 180°
And we can substitute the values we have:
5a + 18 + 24 - a + 8a - 30 = 180
Next, we can combine all like terms:
12a + 12 = 180
12a = 168
a = 14
Now, to find each angle, we can substitute the value of a:
m<AOC = 5a + 18 = 5(14) + 18 = 88°
m<COD = 24 - a = 24 - 14 = 10°
m<DOB = 8a - 30 = 8(14) - 30 = 82°
The smallest angle is <COD with a measure of 10°.

A bakery sells 5394 donuts in 2010. The bakery sells 10,874 donuts in 2015. Write a linear model that represents the number y of donuts that the bakery sells x years after 2010.
Answer:
y = 1096x + 5394
Step-by-step explanation:
Given that
The bakery sells 5394 donuts in 2010
And, the bakery sells 10,874 donuts in 2015
We need to write the linear model
So here
we assume that the x be the no of years after 2010
And, y be the no of donuts
Now
x_1 = 0, y_1 = 5394
x_2 = 5, y_2 = 10874
Now the slope is
m = (y_2 - y_1) ÷ (x_2 - x_1)
= (10874 - 5394) ÷ (5 - 0)
= 1,096
Now
y - y_1 = m(x - x_1)
y - 5394 = 1096(x - 0)
y - 5394 = 1096x - 0
y = 1096x + 5394
Triangle ABC has coordinates A(-3, 2), B(-2, 4), and C(-2, 1). If the triangle is reflected over the y-axis, what are the coordinates of A'?
Answer:
A=3, 2
B= 2,4
C= 2, 1
If i'm not wrong
Point A(-3,2)) reflected over the y-axis becomes: A'(3,2).
Point B(-2,4) reflected over the y-axis becomes: B'(2,4).
Point C(-2,1) reflected over the y-axis becomes: C'(2,1).

None of the answers shown are correct
Step-by-step explanation:
12 : 30 = x : 50
Handle as a proportion
12/30 = x/50
multiply both sides by 50
12/30 * 50 = x
20 = x

If a/b=6, b/x=36, and a=36, what is the value of 1/x?
A) 1/2
B) 2
C) 3/2
D) 4
E) 6
Answer:
E) 6
Step-by-step explanation:
a/b = 6
36/b = 6
6b = 36
b = 36/6 = 6
b/x = 36
6/x = 36
36x = 6
x = 6/36 = 1/6
hence 1/x = 6
Answer:
E) 6
Step-by-step explanation:
a/b=6, b/x=36, and a=36
=>a = 6b
36 = 6b => b =6
b/x = 36 => x = b/36 = 6/36
so, 1/x = 36/6 = 6

this test is about angles, and i am having trouble with it.
Answer:
x = 9
Step-by-step explanation:
congruent angles have the same measure as each other
so;
4x + 14 = 6x - 4
(rearrange)
14 + 4 = 6x - 4x
(solve)
18 = 2x
(simplify)
18 divide 2 = 9
so;
9 = x
