Daniel [21]

Answer:

D. 6 units to the right and 3 units up

Step-by-step explanation:

Given

Point (6,3)

Required

Position of the point.

The general format if a coordinated grid is (x,y)

Where x and y represent the x and y axis respectively

The following conditions are to be considered when positioning a point on a coordinate grid.

1. If x is positive, then it points to the right;

2. If x is negative, then it points to the left

3. If y is positive, then it points upwards

4. If y is negative, then it points downwards

Having said this;

By comparison

x = 6 and y = 3

x and y are both positive.

Condition 1 and 3 above are satisfied.

Hence, the grid coordinates is 6 units to the right and 3 units upwards.

Option D is correct and others are incorrect

Ben is making salsa.He needs 1/3 cups of chilies for each bach of salsa.Ben has 5/6 cup green chilies.How many baches of salsa c

FromTheMoon [43]

Answer:

The number of batches Ben can make with 5/6 cup of green chilies is $2\frac{1}{2}$ batches of salsa.

Step-by-step explanation:

From the question,

Ben needs 1/3 cups of chilies for a batch of salsa.

To determine how many batches of salsa he can make with 5/6 cup of green chilies,

Let the number of batches Ben can make with 5/6 cup of green chilies be x.

Now,

If 1/3 cups of green chilies is needed for 1 batch,

Then, 5/6 cups of green chilies will make x batches

1/3 × x = 5/6 × 1

x = 5/6 ÷ 1/3

x = $\frac{5}{6} \div \frac{1}{3}$

x = $\frac{5}{6} \times \frac{3}{1}$

x = $\frac{15}{6}$

x = $\frac{5}{2}$

x = $2\frac{1}{2}$

Hence, the number of batches Ben can make with 5/6 cup of green chilies is $2\frac{1}{2}$ batches of salsa.

1. It costs $3.45 to buy 3/4 lb of chopped walnuts. How much would it cost to purchase

konstantin123 [22]

Answer:

$34.50

Step-by-step explanation:

First, how many 3/4 lbs are in 7.5 lbs?

7.5 lbs = 15/2 lbs.

(15/2) / (3/4) = 10

There are 10 "3/4" lbs in 7.5 lbs.

So, if it costs $3.45 to purchase 3/4 lbs of chopped walnuts, it would cost $3.45 times 10 dollars to purchase 7.5 lbs of chopped walnuts, or $34.50.

Let me know if this helps!
