Wilson began watering his garden with a watering can that was completely full. The amount of water in the can as Wilson was wate

givi [52]

Answer:

Option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.

Step-by-step explanation:

Given is the graph of Amount of water (in gallons) v/s Time (in seconds).

It is a linear graph whose general equation is given as follows:-

y=mx+b.

Where y = Amount of water, x = Time, m = slope, b = y-intercept (when time is zero).

Finding slope of line, m = (2.3 - 2.5)/(1 - 0) = -0.2 gallons per second.

Finding y-intercept of line, b = 2.5 gallons (at t=0).

Hence, option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.

Joseph needs 6 1/2 cups of cooked rice for a recipe of nasi gorang. If 2 cups of uncooked rice with 2 1/2 cups of water make 4 1

liraira [26]

Answer:

The number of the cups of uncooked rice is 3 cups

The number of the cups of water is $3\frac{3}{4}$ cups

Step-by-step explanation:

* Let us read the recipe of Nasi Gorang

- 2 cups of uncooked rice need $2\frac{1}{2}$ cups of water to

make $4\frac{1}{3}$ cups of cooked rice

- Joseph needs $6\frac{1}{2}$ cups of cooked rice

- We need to know how many cups of uncooked rice Joshep needs

for this recipe and how much water should be added

* We can solve this problem by using the ratio method

⇒ uncooked cups : water cups : cooked cups

⇒ 2 : $2\frac{1}{2}$ : $4\frac{1}{3}$

⇒ x : y : $6\frac{1}{2}$

- By using cross multiplication

∵ x ( $4\frac{1}{3}$ ) = 2 ( $6\frac{1}{2}$ )

∵ $4\frac{1}{3}$ = $\frac{13}{3}$

∵ $6\frac{1}{2}$ = $\frac{13}{2}$

∴ x ( $\frac{13}{3}$ ) = 2 ( $\frac{13}{2}$ )

∴ $\frac{13}{3}$ x = 13

- Divide both sides by $\frac{13}{3}$

∴ x = 3

∴ The number of the cups of uncooked rice is 3 cups

- By using cross multiplication

∵ y ( $4\frac{1}{3}$ ) = ( $2\frac{1}{2}$ )( $6\frac{1}{2}$ )

∵ $2\frac{1}{2}$ = $\frac{5}{2}$

∵ $6\frac{1}{2}$ = $\frac{13}{2}$

∵ $4\frac{1}{3}$ = $\frac{13}{3}$

∴ $\frac{13}{3}$ y = ( $\frac{5}{2}$ )( $\frac{13}{2}$ )

∴ $\frac{13}{3}$ y = $\frac{65}{4}$

- Divide both sides by $\frac{13}{3}$

∴ y = $3\frac{3}{4}$

∴ The number of the cups of water is $3\frac{3}{4}$ cups

What is the slope of a line that is perpendicular to the line represented by the equation 2x−5=−y?

Liula [17]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

First, you need to get the equation into y = mx + b form, like this:

Add y to both sides to get y + 2x − 5= 0

Then subtract 2x to get y - 5 = -2x

Add 5 to get y = -2x + 5

Now we know the slope is -2, or -2/1.

A line that is perpendicular to it has a slope that is the first line's slope's opposite reciprocal. This means flip the fraction upside down and change the sign, which gives you positive 1/2.

Which graph shows the graph of a circle with equation x^2+(y-4)^2=16

Vinil7 [7]

Answer:

The option on the top left

Step-by-step explanation:

As the equation is $x^2+(y-4)^2=16$

We know that the circle will have a radius of 4 and will be shifted 4 units up
