0.30 • 18 = 5.4
0.30 • 40 = 12
0.30 • 9 = 2.7
0.30 • 70 = 21
0.30 • 48 = 14.4
0.30 • 26 = 7.8
0.30 • 14 = 4.2
Add the sums together which would be 67.5
Subtract $100 from $67.5 and that would be $32.5

State the Rules for Reflection across the x-axis and across the y-axis

prisoha [69]

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).

A landscaper receives a discount on each plant purchased. The original price of each plant is x dollars. The landscaper purchase

prisoha [69]

Answer:

Step-by-step explanation:

Discount is a form of consideration in price or amount given to a customer on a sale of goods. It can be deduced from the question that;

The original price of each plant = $x

Number of plants purchased = 20

Price of the number of plants purchased without discount = $20x

Amount paid for the 20 plants with discount = $(20x - 80)

Thus,

The discount on the 20 plants = $80

Discount on each plant = $\frac{total discount on plants}{number of plants purchased}$

= $\frac{80}{20}$

= $4

Discount on each plant = $4

Therefore, each plant was discounted by $4.

A football team received 3 penalties for 15 yards each, 1 for5 yards, and1 for half the distance to the goal from the 34- yard l

Effectus [21]

The first penalty they received is three 15 yards so total yards is 3(15 yards)
the second penalty is one 5 yard
the last penalty is half the 34 yard line(34 yard)/2
total change = 3(15 yards) + 5 yrad + (34 yard)/2
= 45 yards + 5 yards + 17 yards= 67yards

Martha estimated the quotient of -71.81 and -8.02 using

steposvetlana [31]

Option 2

Martha estimated the quotient. Martha error was she should have rounded -8.02 to -8.

SOLUTION:

Given that, Martha estimated the quotient of -71.81 and -8.02 using rounding to the nearest whole number.

And she committed an mistake. We have to find the error made by Martha while calculating quotient.

She treated -71.81 to be 72 and -8.02 to be 9. As both the number are negative there will be no problem when we get quotient.

When treated as above she got quotient as 8.

But in general, the quotient is not 8.

If we see options, we derive an conclusion.

Option (1)

she should have rounded 71.81 to 70, no this is not correct as 72 is nearest whole number.

Option (2)

she should have rounded 8.02 to 8, yes this is correct conclusion.

Option (3)

she should have divided 8 by 72, no this is not correct, we should divided 72 by 8.

Option (4)

she didn’t make an error, this is wrong as in 2nd option we caught an error.

Hence, second option is correct.
