Answer:
The answer is 105.5 kcal/slice of bread.
Step-by-step explanation:
The kcal per gram of:
- protein = 4kcal/g.
- carbohydrate = 4kcal/g.
- fat = 9kcal/g.
Now, you have:
- 1.5 g of fat + 19g of carbohydrate + 4g of protein = 1 slice of bread.
If we multiply the amount of components by his kcal:
- 1.5g * 9kcal/g + 19g * 4kcal/g + 4g * 4kcal/g;
Now gram/gram = 1, and we can cancel the grams in the equation:
- 1.5* 9kcal + 19 * 4kcal + 4 * 4kcal = 105.5kcal;
Finally, the result of the kcal of the slice bread is:
- 105.5 kcal/slice of bread.
Answer: 87.96π
Step-by-step explanation:
A=2πrh+2πr2
A=2π2(5)+2π2(2)
A=87.96π

Find Slope:
--------------------------------------------------------------------------------------------------------
y = 1/4x - 7
Slope = 1/4
Perpendicular slope = -4 (Negative reciprocal)
--------------------------------------------------------------------------------------------------------
Substitute slope into the general equation y = mx + b:
--------------------------------------------------------------------------------------------------------
y = -4x + b
--------------------------------------------------------------------------------------------------------
Find y-intercept:
--------------------------------------------------------------------------------------------------------
at point (-2, -6)
-6 = -4(-2) + b
-6 = 8 + b
b = -6 - 8
b = -14
--------------------------------------------------------------------------------------------------------
Substitute b = -14 into the equation:
--------------------------------------------------------------------------------------------------------
y = -4x + b
y = -4x - 14
--------------------------------------------------------------------------------------------------------
Equation:
--------------------------------------------------------------------------------------------------------
y = -4x - 14
y + 6 = -4x - 8 \\add 6 to both sides
y + 6 = -4(x + 2) \\Take out common factor -4
--------------------------------------------------------------------------------------------------------
Answer: y + 6 = -4(x + 2) (Answer D)
--------------------------------------------------------------------------------------------------------
Answer:
Solve the equation. 2x – 3 = 15
x = 6
x = 9
x = 24
x = 36
Answer:
x = -7
Step-by-step explanation:
-5( x + 3 ) = 20
Distributive property ( multiply whatever is in the parenthesis by -5)
-5 * x + -5 * 3 = 20
-5x - 15 = 20
Add 15 on both sides
-5x - 15 + 15 = 20 + 15
-5x = 35
Divide by -5 on both sides to isolate the variable
-5x/-5 = 35/-5
x = -7
Check...
Substitute the "x" with -7 since we already got that as our solution
-5( x + 3 ) = 20
-5( -7 + 3 ) = 20
Distributive property
-5 * -7 + -5 * 3 = 20
35 - 15 = 20
20 = 20 CORRECT
Hope this helped!
Have a supercalifragilisticexpialidocious day!
