Help!! I’m sooo stuck!

stepladder [879]

Answer:

1. 24 quarts. 2. 85 seconds.

Step-by-step explanation:

1. We need to know how many 2/3 are in 4.

if 3/3 are in 1 cup, then 12/3 are in 4 cups.

there are 6 twos in 12, so there are 6*2/3 cups in 4 cups.

Each 2/3 needs 4 quarts of green, and we have six times that.

6*4 = 24, so we need 24 quarts of green paint.

2. The 12.75 miles would go in the "d" or distance part of the equation.

d = 0.15t

12.75 = 0.15t (divide both sides by 0.15)

12.75/0.15 = 0.15t/0.15

t = 85, so 85 seconds.

12.75 miles isn't the distance between the two cities, it's much farther, so this answer makes sense.

Priya bought two plants for a science experiment. When she brought them home, the first plant was 5cm tall and the second plant

musickatia [10]

Answer:

a. After 2 weeks the first plant will be taller.

b. After 10 weeks the second plant will be taller.

c. After 4 weeks both the plant will be of the same height.

d. This is the condition for the height of the first plant is greater than that of the second plant.

Step-by-step explanation:

The first plant was 5 cm tall and the second plant was 4 cm.

Again, the first plant has grown 0.5 cm a week and the second plant has grown 0.75 cm a week.

So, the height of the first plant after W weeks will be (5 + 0.5W) cm. and the height of the second plant after W weeks will be (4 + 0.75W) cm.

a. After 2 weeks the first plant will be (5 + 2× 0.5) = 6 cm.

And after 2 weeks the second plant will be (4 + 2 × 0.75) = 5.5 cm

So, after 2 weeks the first plant will be taller.

b. After 10 weeks the first plant will be (5 + 10× 0.5) = 10 cm.

And after 10 weeks the second plant will be (4 + 10 × 0.75) = 11.5 cm

So, after 10 weeks the second plant will be taller.

c. If 5 + 0.5w = 4 + 0.75w, give w = 4 weeks, then this means that after 4 weeks both the plant will be of the same height.

d. If, 5 + 0.5w > 4 + 0.75w, then it means that this condition is for the height of the first plant will be more than the second plant. (Answer)

2. Suppose there are 50 cats in a neighborhood. The ratio of cats to dogs is 2/1 . many dogs are in the neighborhood? (4 points)

Rus_ich [418]

Answer: 25 Dogs

Reason: If the ratio of cats to dogs is 2/1, there are 2 cats for every 1 dog. That would mean that the number of cats is double the number of dogs. 25 x 2 = 50

For each ordered pair determine whether it is a solution to the system of equations 2x-7y=8 -3x+2y=5

rodikova [14]

Answer:

The solution of this system of linear equations is $(x,y) = (-3,-2)$ .

Step-by-step explanation:

Let be the following system of linear equations:

$2\cdot x - 7\cdot y = 8$ (1)

$-3\cdot x + 2\cdot y = 5$ (2)

From (1) we clear $y$ :

$2\cdot x -8 = 7\cdot y$

$y = \frac{2\cdot x - 8}{7}$

And we apply this variable in (2):

$-3\cdot x+2\cdot \left(\frac{2\cdot x -8}{7} \right)= 5$

$-3\cdot x +\frac{4}{7} \cdot x -\frac{16}{7} = 5$

$-\frac{17}{7}\cdot x = \frac{51}{7}$

$x = -\frac{51}{17}$

$x = -3$

And the value of $y$ is:

$y = \frac{2\cdot (-3)-8}{7}$

$y = -\frac{14}{7}$

$y = -2$

The solution of this system of linear equations is $(x,y) = (-3,-2)$ .
