Answer:
4 ft per second
Step-by-step explanation:
We are given that it takes 50 seconds to go 200 feet

9. Matt bought a new crate for his dog. The old crate was 8 square feet, and the new crate was 12 square feet. What is the percent increase in the space?
Answers
Solution:
It is given that :
Area of old crate = 8 square feet
Area of the new crate = 12 square feet
Therefore difference in the area = 12 - 8
= 4 square feet
Now the percentage increase in the area of the crate is given by :
[tex]$=\frac{\text{difference in the area of crate}}{\text{original area of crate}} \times 100$[/tex]
[tex]$=\frac{4}{8} \times 100$[/tex]
= 50%
So the percentage increase in space is 50%

If c varies diráctly as (1 + 1) and c= 8, when r = 3, calculate the value ofr when c= 20.
(4marks)
Answers
c = k(r + 1)
8 = k(3 + 1)
8 = 4k
8/4 = k
2 = k
c=2(r + 1)
When c = 20, then
20 = 2(r + 1)
20 = 2r + 2
20 - 2 = 2r
18 = 2r
18/2 = r
9 = r
Therefore, the value of r is 9 when c is 20.

24 + 0.44x = 19 + 1.69x
Answers
Answer:
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 + 0.44x - 1.69x = 19
-1.25x = 19 - 24
-1.25x = -5
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 - 19 = 1.69x - 0.44x
5 = 1.25x
1.25x = 5
x = 5/1.25

Solve: 2.3 = v + 0.47 v = _____
Answers
Answer:
2.3=v+0.47v=
We move all terms to the left:
2.3-(v+0.47v)=0
We add all the numbers together, and all the variables
-(+1.47v)+2.3=0
We get rid of parentheses
-1.47v+2.3=0
We move all terms containing v to the left, all other terms to the right
-1.47v=-2.3
v=-2.3/-1.47
v=1+0.83/1.47
Answer:
[tex]v = 1.564[/tex]
Step-by-step explanation:
[tex]1v + 0.47v = 2.3[/tex]
[tex] = > 1.47v = 2.3[/tex]
[tex] = > v = \frac{2.3}{1.47} = 1.564[/tex]

A) Converse and Inverse B) Inverse and Contrapositive C) Conditional Statement and Converse D) Conditional Statement and Contrapositive
Answers
Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.
Two or more lines which have no intersections but are not parallel, known as skew lines.
Option D is correct.
Conditional Statement: If two lines are parallel, then they do not intersect.
Converse: If two lines do not intersect, then they are parallel.
Inverse: If two lines are not parallel, then they intersect
Contrapositive: If two lines intersect, then they are not parallel.
Thus, option (D) Conditional Statement and Contrapositive , is correct.
Converse and Inverse are false because skew lines are a type of lines which are neither parallel nor intersecting in 3D

5×3+2=17.
Answer:
Liza is 17 years old.
Step-by-step explanation:
Ley 'x' be the age of Liza's younger sister
As Liza’s age is two more than thrice the age of her younger sisterso the equation of Liza's age will be:
Liza's age = 3x+2
As x = 5 years is Liza's younger sister age
so
Liza's age = 3(5)+2
= 15+2
= 17 years
Therefore, Liza is 17 years old.
