How can you find this distance (-3,7),(0,4) in words

Bezzdna [24]

Answer:

The distance between these two given points is:

$3\sqrt{2}$

Step-by-step explanation:

We are given two points:

(-3,7),(0,4)

The distance between two points (a,b) and (c,d) is given by the distance formula as:

$\sqrt{(c-a)^2+(d-b)^2$

similarly we can find the length of a line segment by considering the distance between the end points of the line segment.

So here (a,b)=(-3,7)

and (c,d)=(0,4).

Hence distance between these two points is given by:

$\sqrt{(0-(-3))^2+(4-7)^2}=\sqrt{(3)^2+(-3)^2}=\sqrt{9+9}\\ \\=\sqrt{18} \\\\=3\sqrt{2}$

Each carton 12 eggs. There are 2 full cartons in the refrigerator. Margot uses 3 eggs to make a quiche. How many eggs are left.

3241004551 [841]

Answer:

Answer: There are 21 eggs left.

Step-by-step explanation:

One carton has 12 eggs.

2 cartons are two times one carton, so two cartons have 2 times 12 eggs.

2 * 12 = 24

There are 24 eggs in two cartons.

Margot uses 3 eggs. We subtract 3 eggs from 24 eggs.

24 - 3 = 21

Answer: There are 21 eggs left.

Convert the rate 1000 fluid ounces per 2 hours to cups per minute

Ronch [10]

There are 8 ounces in a cup, so there are 125 cups in 1000 ounces.
1000 / 8 = 125
there are 60 minutes in an hour and 120 minutes in 2 hours
so 1000 ounces / 2 hours is
125 cups / 120 minutes
125 / 120 = 1.04 cups per minute

Check your work
multiply times 60 to get cups per hour
1.04 * 60 = 62.4 cups per hour
multiply times 8 to get ounces per hour
62.4 * 8 = 499.2
multiply times 2 to get ounces per 2 hours
499.2 * 2 = 998.4
the number is not quite 1000 due to rounding the 125 / 120 as it is closer to 1.041666666666667

Three solutions for the linear equation 4 −3 = 1.

FrozenT [24]

Answer:

(1, 1), (2, 2.333) and (3, 3.666).

Step-by-step explanation:

So, for x = 1, we have:

4*1 - 3y = 1

3y = 3

y = 1

For x = 2, we have:

4*2 - 3y = 1

3y = 7

y = 2.333

For x = 3, we have:

4*3 - 3y = 1

3y = 11

y = 3.666

The points we need to plot is (1, 1), (2, 2.333) and (3, 3.666).

How do you find the slope of the points: (19,-16),(-7,-15)?

nirvana33 [79]

Answer:

$\Huge\boxed{\mathsf{\frac{1}{26} }}$

Step-by-step explanation:

SLOPE FORMULA:

$\longrightarrow \displaystyle \mathsf{\frac{Y_2-Y_1}{X_2-X_1} }}$

Y₂=(-15)

Y₁=(-16)

X₂=(-7)

X₁=19

Solve.

$\displaystyle \mathsf{\frac{(-15)-(-16)}{(-7)-19}=\frac{(-15)+16}{(-7)-19}=\frac{1}{-26}=\boxed{\mathsf{\frac{1}{26}} } }}}}$

So, the slope is 1/26.
