Answer:

The enrollment decreased by 20%

Step-by-step explanation:

You know it decreased, so you can get rid of the first two options, then you can look at the numbers and figure out that the enrollment didn't drop by 80% percent, so the answer is 20%

Three fifths of the children in a school are boys. 7/8 of the girls in the school are right-handed. What fraction of the childre
Kaylis [27]

Answer:

To find the answer we only need to know,

Total no.of girls and Total no.of right handed girls.

So,

Total no.of right handed girls = 7/8

Total no.of girls                        = 8/8 (as given in question)

Total no.of left handed girls is,

(Fraction of total no.of girls) - (Fraction of total no.of left handed girls)

= 8/8 - 7/8

= 1/8

∴ 1/8 of the girls in the school are left handed.

A. What would be the cost of the Standard Daily Rate plus Mileage plan?
Jobisdone [24]

Answer:

Part a) \$190

Part b) \$315

Part c) Standard Daily Rate plus Mileage plan

Step-by-step explanation:

Part a) What would be the cost of the Standard Daily Rate plus Mileage plan?

Let

y ----> the total cost

x ----> the number of kilometers

we have that

For a Luxury car

y=70+0.30x

For x=400 km

substitute

y=70+0.30(400)

y=\$190

Part b) What would be the cost of the Unlimited Mileage plan?

we know that

The Unlimited Mileage plan for a Luxury car is $105 per day (see the table)

The trip are three days

so

To find the total cost multiply $105 by 3

3(\$105)=\$315

Part c) Which is the better plan?

Compare

\$190 < \$315

therefore

For this trip the better plan is the Standard Daily Rate plus Mileage plan

1/3x² + x+5/3x² = 1/9<br><br>HAHAHAHA......​
mr_godi [17]

Answer:

Now, 3x 2+x+5⩾0

This is because b² −4ac=1−4×5×3

=−59 (roots are imaginary)

3x²+x+5=(x−3)² =x²+9−6x and x−3⩾0

2x²+7x−4=0

2x²+8x−x−4=0

2x(x+4)−1(x+4)=0

(2x−1)(x+4)=0

x= 1/2 and−4 but x≥3

∴ No solution.

lol hehehe
