Abigail is putting tiles on a table top. She needs 48 tiles for each of 8 rows. Each row will have 6 white tiles.
almond37 [142]
I think its like this 
each row has 6 white tiles
8 rows = 48 tiles 
48 - 6 = 42
42 x 8 = 336
so 8 rows = 6 white tiles and 42 purple tiles to make 48 tiles so she will need 336 more tiles to make each 8 rows have 48 tiles

hope this helps : )

Bob parked his car at the local garage. If his car stayed for one hour, he would have been charged $6.00. If he stayed for 4 hou
Nitella [24]

Answer:

Initial charge is $2.5

Hourly charge is $3.5/hr

Equation is y=3.5x+2.5

Step-by-step explanation:

Getting slope

Get fixed charge

Get equation

The slope can be found as follows. For 1 hour, charges is $6 so making time in x axis while money charged in y axis, the first coordinate is (1, 6) while for 4 hours with charge of $16.5 the coordinate will be (4, 16.5)

The slope will be given by dividing change in y axis to change in x axis. This will be (16.5-6)/(4-1)=3.5

To get the fixed charge

Using the equation y=mx+c where m is slope while c is fixed charge, x is time and y is total cost then for 1 hour

6=3.5(1)+c

C=6-3.5=2.5

Therefore, generally the equation will be y=3.5x+2.5

Initial charge is $2.5

Hourly charge is $3.5/hr

Equation is y=3.5x+2.5

A machine produces small cans that are used for baked beans. The probabil- ity that the can is in perfect shape is 0.9. The prob
Elis [28]

Answer:

0.9783 = 97.83% probability that a can that gets shipped for use will be of perfect shape

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Shipped for use

Event B: Perfect shape

Probability of being shipped for use:

Perfect shape(0.9 probability) or unnoticeable dent(0.02 probability). So

P(A) = 0.9 + 0.02 = 0.92

Being shipped for use and being in perfect shape.

0.9 probability, so P(A \cap B) = 0.9

What is the probability that a can that gets shipped for use will be of perfect shape?

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.9}{0.92} = 0.9783

0.9783 = 97.83% probability that a can that gets shipped for use will be of perfect shape

Write the expression: six divided by the quantity x plus y. A) 6 x + y B) x + y 6 C) x 6 + y D) 6 x + y
jekas [21]

6 is what you're dividing by so it goes on top as the numerator and x + y is the denominator: \frac{6}{x+y}
