Answers

Answer 1

Answer:

Answer:

3/4.

Step-by-step explanation:

5/16 + 7/16

= (5+7)/16

= 12/16

= 3/4.

20 and 60 degrees

Answers

Answer:

Other two angles are 80 and 80 degrees

Step-by-step explanation:

In an isosceles triangle , one angle measures 20 degrees.

In an isosceles triangle two angles are equal

In a triangle , we have three angles

one angle is 20 degree. sum of angles in a triangle is 180 degree

other two angles is equal to 180 - 20 = 160

other two angles are of equal degree so we divide by 2

160/2= 80

Other two angles are 80 and 80 degrees

80+80=160+20=180

triangles should always equal 180

What is the solution to y = 0.7x for the replacement set x = {2}?.

Answers

The question ask to solve and compute the said problem if x = 2 and the equation is y=0.7x. In that alone, the value of y is 1.4 so it means its solution, by means of representing it coordinate, it should be (2,1.4). I hope you are satisfied with my answer and feel free to ask for more

Answer:

-1/6

Step-by-step explanation:

To find the slope we use

m = (y2-y1)/(x2-x1)

= (-4-8)/( 1-3)

= -12/-2

We want a line perpendicular, so we need the negative reciprocal

- (1/6)

In one day, Joe consumes 530 calories by drinking 1 serving of juice, 2 servings of milk, and 1 soda. Darius consumes 370 calories by drinking 2 servings of juice and 1 serving of milk. Marian consumes 510 calories by drinking 3 servings of milk and 1 soda. Using matrices to solve, how many calories are in 1 serving of milk?A. 90
B. 110
C. 130
D. 180

Answers

Using matrices to solve, the number of calories that are in 1 serving of milk is; 110 Calories

How to solve Linear Programming problems?

Let the calories in one serving of milk be x

Let the calories in one serving of juice be y

Let the calories in one serving of soda be z

Thus, for Joe, equation to show amount of calories is;;

2x + y + z = 530 -----(1)

For Darius, equation to show amount of calories is; ;

x + 2y = 370 ------(2)

For Marian, equation to show amount of calories is;

3x + z = 510 ------(3)

Using matrix calculator online to calculate this 3 equations, we have;

x = 110 calories.

#SPJ2

Answer:

the answer is B on ed2020

Step-by-step explanation:

for answer b, if you subtract 330 from 510 you get soda = 180 cal. then if you subtract 110 from 370 you get 260, and 260 divided by two (he consumed 2 juice) equals 130.

so you have soda = 180 cal and juice = 130 cal

if you plug it into joe's calorie intake you do 130 (1 serving of juice) + 180 (1 serving of soda) and + 220 (two servings of milk) you get 530 which is joe's total calorie intake in liquids, so B (110) is correct
