Answer:

Step-by-step explanation:

1. We know that Mike has 40 baseball cards total. We know that Tim has 5 less than half of the cards that Mike has.

2. First, we need to divide 40 (Mike's total amount of baseball cards) by 2 or multiply that by 1/2. That gives us 20 baseball cards.

3. Tim has 5 less than half of Mike's deck (20 baseball cards) so we have to take away 5 more cards. 20 - 5 = 15. Tim has 15 baseball cards.

The population of Mexico in 2000 was approximately 103,970,000 and the land area was 761,700 square miles. The population increa

nata0808 [166]

Answer: 19 people per sqaure mile

Step-by-step explanation:

Given : Population in 2000 = 103,970,000

The population increased by 13.4% in 2010.

Population in 2010 = 103,970,000 + 13.4% of (103,970,000)

= 103,970,000+ (0.134)(103,970,000)

= 103,970,000(1+0.134)

=103,970,000(1.134)

=117,901,980

In 2000,

Population density= $\dfrac{\text{Population}}{\text{Area}}$

$=\dfrac{103970000}{761700}\approx 136\text{ people per square mile}$

In 2010

Population density = $\dfrac{\text{Population}}{\text{Area}}$

$=\dfrac{117901980}{761700}\approx155\text{ people per square mile}$

Difference = 155-136 = 19 people per sqaure mile

Hence, the increase in population density in 2010 = 19 people per sqaure mile

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by h = 88t - 16t ^2. How

kozerog [31]

Answer:

it will take 5.5 seconds to hit the ground

Step-by-step explanation:

A projectile is shot vertically from the ground level. It’s height h, in feet, after t seconds is given by $h = 88t - 16t ^2$

When the projectile hits the ground then the height becomes 0

$h = 88t - 16t ^2$

$0 = 88t - 16t ^2$

GCF is -8t

$0 = 8t(11 - 2t)$

now set each factor =0 and solve for t

$8t=0, t=0$

$11-2t=0, t=\frac{11}{2}$

So it will take 5.5 seconds to hit the ground
