Answer: 200%

Step-by-step explanation: Use the formula found below,

Percent change = New - Old

|Old|

× 100%

Percent change = 24 - 8

|8|

× 100% =

× 100 = 200% (increase)

Where: 8 is the old value and 24 is the new value. In this case we have a positive change (increase) of 200 percent because the new value is greater than the old value.

Tyrone makes a scale drawing of his backyard. The scale from the backyard to the drawing is 2 ft to 1 in. The width of the patio

Sphinxa [80]

Answer:

The width of Tyrone's actual patio is 16 feet

Step-by-step explanation:

$\frac{2ft}{1in}$ = $\frac{x}{8}$ If we look at what we know, we see that the scale tells us that 1 inch is proportional to 2 ft. What do we need to multiple 1 inch by to get 8 inches? 8. So, we multiply 2 feet by 8 to get the actual size of the patio which is 16 feet.

A culture started with 3000 bacteria. After 2 hours it grew to 3300 bacteria. Predict how many bacteria will be present after 16

bixtya [17]

Answer:

$6,430\ bacteria$

Step-by-step explanation:

we have a exponential function of the form

$y=a(1+r)^{x}$

where

y is the population of bacteria

a is the initial value

r is the rate of growth

x is the number of hours

we have

a=3,000 bacteria

$y=3,000(1+r)^{x}$

For x=2, y=3,300

substitute

$3,300=3,000(1+r)^{2}$

$(3,300/3,000)=(1+r)^{2}$

Apply square root both sides

$1+r=\sqrt{3.3/3}$

$r=\sqrt{3.3/3}-1$

$r=0.0488$

$r=4.88\%$

substitute in the equation

$y=3,000(1+0.0488)^{x}$

$y=3,000(1.0488)^{x}$

Predict how many bacteria will be present after 16 hours

For x=16 hours

substitute

$y=3,000(1.0488)^{16}$

$y=6,430\ bacteria$

May someone tell me what the value of x is ?

Arisa [49]

Answer:

maybe 11? because it says to Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

Select the example which illustrates the distributive property of 7 × 39

Lemur [1.5K]

Answer:

d) 7(30 + 9) = 7(30) + 7(9)

Step-by-step explanation:

Distributive method:

a(b + c) = ab + ac

Here given:

7 × 39

Among the option's:

1st option (7 + 3) (7 + 9) is wrong, changes final answer.

2nd option (7 × 30) + 9 is wrong, changes final answer.

3rd option 39 × 7 shows commutative property of multiplication.

4th option show distributive method.
