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?
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%

The solution of the equation is x= .
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
Step 1: Cross-Multiply
What cross multiply basically means is that you take both sides of the equation and you multiply my the opposite sides. So you take the top of the left fraction and multiply it by the bottom of the right fraction. You then have an equal sign and then have the bottom of the left fraction multiplied by the top of the right fraction.
[tex]\frac{2}{7}=\frac{6x}{4x+17}[/tex]
[tex]2(4x+17)=7(6x)[/tex]
Step 2: Distribute
[tex]2(4x+17)=7(6x)[/tex]
[tex](2*4x)+(2*17)=(7*6x)[/tex]
[tex]8x+34=42x[/tex]
Step 3: Subtract 8x from both sides
[tex]8x + 34- 8x = 42x - 8x[/tex]
[tex]34=34x[/tex]
Step 4: Divide both sides by 34
[tex]34/34 = 34x/34[/tex]
[tex]1=x[/tex]
Answer: [tex]x=1[/tex]

A large basket of fruit contains 3 oranges, 2 apples and 5 bananas. If a piece of fruit is chosen
at random, what is the probability of getting an orange or a banana?
Answer:
8/10
Step-by-step explanation:
3+2+5=10 options in total. 3 oranges and 5 bananas means 3+5=8 --> 8/10 chance of picking an orange or banana

Liza’s age is two more than thrice the age of her younger sister.if her sister is 5 years old, how old is Liza?
Answer:
17 years old.
Step-by-step explanation:
sisters age:5
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.

Suppose you are constructing a LEGO Technic Land Rover Defender with a total of 2573 pieces. You have already put together 253 pieces. Every minute you add 5 more pieces. Is the relationship linear? How do you know?
Answer: Yes it is
Step-by-step explanation:
A linear relationship simply put, is a relationship between variables that when constructed, forms a straight line. This happens when y changes at a constant rate if x changes by a constant rate as well for instance, 1.
From this question, assume x is minutes and y is the total number of pieces put together. This means that every time x (minutes) increases by 1, y increases by 5 pieces.
The formula would look like this;
y = 5x + 253
This is a formula for a straight line so indeed, this relationship is linear.
Find the solution for this system of equations:
y = -6x - 8
y = 46
O A) (24, -36)
OB) (36,-5)

The time, t, required to empty a tank varies inversely as the rate, r, of
pumping. If a pump can empty a tank in 2.5 hours at a rate of 400 gallons per
minute, how long will it take to empty a tank at 500 gallons per minute?
Answer:
2 hours
Step-by-step explanation:
2.5 * 400 = 1000
1000 / 500 = 2

Answer:
a) 3x + y = -5 & b) y = 1/3 ( 21- 9x )
Step-by-step explanation:
a)
3x + y = -5
y = -3x -5
b)
y = 1/3 ( 21 - 9x)
y = -3x + 7
y = 3x + 2.5
the slop is to be same in the parallel lines. slop means m in ( y = mx + c )
so a) & b) are parallel lines. since their m is -3 .
