Answer:
∠3 = 107°
Step-by-step explanation:
Similar to the other question, ∠3 and ∠4 are supplementary and add up to 180 degrees as they make up the entirety of a straight line.
∠4 is 73°, so ∠3 has to be 107°.
Find slope
(y2-y1)/(x2-x1) is slope
(11-3)/(1-(-1))=8/2=4
y=4x+b
input a point
(1,11)
x=1
y=11
11=4(1)+b
11=4+b
minus 4 from both sides
7=b
the equatin is
y=4x+7
the closest one
minus 4x from both sides
y-4x=7
times everybody by -1
4x-y=-7
last choice is answer
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.
It would be 8X5=40 and 21/7=3
Answer:
$480
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Original cost including sales tax = $1,200
Discount = 60%
So, we can calculate the cost of TV after discount by using following formula:
Cost of TV after discount = $1,200 - ( $1,200 × 60%)
= $1,200 - $720
= $480
Hence, Cost of TV after discount is $480.
