When a lilac bush is planted, it is 24 inches tall. Each month, it grows 6 inches taller. How tall will It get over time?

Dependent variable: ______
Independent variable: ______
Equation: ______

Answer:

45%

Step-by-step explanation:

Simply, 25/55 which gives you 0.454545.

Convert that to a percentage and you get 45%

The percentage of people who preferred cheesecake if 50% prefferd fruit cake 1/5 preferred sponge is 40%.

Percentage remaining = 100% - 50%

= 50%

Sponge cake = 1/5

Percentage of sponge cake = 1/5 × 50%

= 1/5 × 0.5

= 10%

Percent that likes cheesecake = Total - (fruits cake + sponge cake)

= 100% - (50% + 10%)

= 100% - (60%)

= 40%

Therefore, the percentage of people who preferred cheesecake if 50% prefferd fruit cake 1/5 preferred sponge is 40%.

The algebraic expression that represents the number of hours Anna and Tamara traveled the first two days is (2x - 1) hours.

We are told that;

On the first day, Anna and Tamara stop for sightseeing and lost 2 hours of travel time.

On the second day, they did not stop for lunch and gained 1 hour.

Now, we are told that x is the number of hours driven per day. Thus, for two days, number of hours driven is expressed as 2x.

Now, since they lost 2 hours on the first day, then total hours travelled is;

2x - 2 hours

On the second day, they gained 1 hour. Thus;

Final total number of hours traveled = 2x - 2 + 1

Final total number of hours traveled = (2x - 1) hours

Thus, we can conclude that the algebraic expression that represents how many hours Anna and Tamara traveled the first two days is (2x - 1) hours.

Answer:

1.05

Step-by-step explanation:

Because 30% of 70 is [tex]30\% \times 70 = \frac{30}{100} \times 70 = 0.3 \times 70 = 21[/tex], so the question becomes "21 is what percent of 2000?"

To answer this, we can solve for [tex]x[/tex] in the equation [tex]21 = x\% \times 2000[/tex], which is:

[tex]21 = x\% \times 2000\\21 = \frac{x}{100} \times 2000\\21 = 20x\\x=\frac{21}{20}=1.05[/tex]

So the answer is 1.05 percent.

The circumference of the circles from biggest to smallest are; 30π, 15π and 7.5π

The formula for area of a circle is;

A = πr²

In geometry, the area enclosed by a circle of radius r is πr². Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter, approximately equal to 3.14159.

The area of a circle formula is useful for measuring the region occupied by a circular field or a plot. Suppose, if you have a circular table, then the area formula will help us to know how much cloth is needed to cover it completely.

The area formula will also help us to know the boundary length i.e., the circumference of the circle. Does a circle have volume? No, a circle doesn't have a volume

Area of entire circle is 706 cm².

Thus;

πr² = 706

r² = 706/π

r = √(706/π)

r ≈ 15

Circumference of biggest circle = 2πr

Circumference of biggest circle = 2π * 15

Circumference of biggest circle = 30π

Circumference of second biggest circle = 2π * (15/2)

The solution to the given simultaneous equation; x + 2y = -4, 2x + 5y = 1 using substitution method is x = -22 and y = 9

x + 2y = -4

2x + 5y = 1

Using Substitution method

From equation (1)

x = -4 - 2y

Substitute x = -4 - 2y into equation (2)

2x + 5y = 1

2(-4 - 2y) + 5y = 1

-8 - 4y + 5y = 1

- 4y + 5y = 1 + 8

y = 9

Substitute y = 9 into

x + 2y = -4

x + 2(9) = -4

x + 18 = -4

x = -4 - 18

x = - 22

Answer:

290 + 5m = 985

Step-by-step explanation:

Given information:

From the given information, we can create the following equation:

Initial payment plus extra amount each month for 5 months equals total payment.

⇒ 290 + 5m = 985

To solve the equation:

Subtract 290 from both sides:

⇒ 290 + 5m - 290 = 985 - 290

⇒ 5m = 695

Divide both sides by 5:

⇒ 5m ÷ 5 = 695 ÷ 5

⇒ m = 139

Therefore, the extra amount George paid each month was $139.

Answer: [tex]\Large\boxed{290+5m=985}[/tex]

Step-by-step explanation:

Given information

Initial cost = $290

Total cost = $985

Number of months = 5 months

Cost each month = ?

Set variable

Let [ m ] be the cost each month

The equation in verble sense

Initial paid + Extra each month = Total cost

Convert verbal equation to mathematical sense

$290 + 5m = $290

Therefore, to find the extra amount paid each month, the equation is [tex]\Large\boxed{290+5m=985}[/tex]

---------------------------------------------------------------------------------------------------------

EXTRA The following will be solving the derived equation, please ignore this part if it is useless for you.

Given equation

290 + 5m = 985

Subtract 290 on both sides

290 + 5m - 290 = 985 - 290

5m = 695

Divide 5 on both sides

5m / 5 = 695 / 5

m = $139

The experimental probability that only 2 of 4 children in a family are boys is 50%.

Experimental probability refers to the chance of an expected success being achieved in a series of experiments conducted.

Experimental probability is the number of times that the expected success occurs as a fraction of the total number of times the experiment was conducted.

Like all probabilities, the experimental probability is based on the likelihood that what the experimenter expects is achieved.

Expected number of boys = 2

The number of children in the family = 4

Experimental probability = 50% (2/4 x 100)

Thus, we can conclude, based on the experimental probability, that 50% (or 2) of the 4 children in the family are boys.

Consider an isoscles trapezoid with angles 75° and 105°.

The theorem used and the angle measures are:

D. corresponding angles postulate

m∠1 = 150°, m∠2 = 150°

According to the corresponding angles postulate, if two angles lie on same relative corner along a transversal that cuts two parallel lines (corresponding angles), then their measures are equal.

Thus, ∠1 and ∠2 are corresponding angles, therefore:

m∠1 = m∠2 [corresponding angles postulate]

Given the following:

m∠1 = (50x − 50)∘,

m∠2 = (20x + 70)∘

Therefore, we would have:

50x − 50 = 20x + 70

Subtract 20x from both sides

50x − 50 - 20x = 20x + 70 - 20x

30x − 50 = 70

Add 50 to both sides of the equation

30x − 50 + 50 = 70 + 50

30x = 120

Divide both sides by 30

30x/30 = 120/30

x = 4

Plug in the value of x

m∠1 = (50x − 50) =  50(4) − 50 = 150°

m∠2 = (20x + 70)∘ = 20(4) + 70 = 150°

Thus, the answer is: D. corresponding angles postulate

m∠1 = 150°, m∠2 = 150°

Step-by-step explanation:

The answer is the first two

The 4.2 inches base length and 36 in.² area of the given triangle and the 5.6 inches base length of the similar triangle gives the area of the similar triangle as 64 square inches

Area of a triangle = (Base length × Height)/2

Area of the given triangle = 36 in.²

Base length of the given triangle = 4.2 inches

Base length of the similar triangle = 5.6 inches

Therefore;

Area of the given triangle = (Base length × Height)/2

Which gives;

36 = (4.2 × h)/2

Where;

h = Height of the given triangle

36 × 2 = 4.2 × h

[tex]h = \mathbf{\frac{36 \times 2}{4.2}} = 17 \frac{1}{7} [/tex]

Height of the given triangle, h = 17+ 1/7

The ratio of corresponding sides of similar triangles are the same, which gives;

[tex] \frac{5.6}{4.2} = \frac{h'}{17 \frac{1}{7}} [/tex]

Where;

h' = The height of the similar triangle

Which gives;

[tex] h' = \frac{5.6}{4.2} \times 17 \frac{1}{7} = 22 \frac{6}{7} [/tex]

The area, A', of the similar triangle is therefore;

[tex] A' = \frac{1}{2} \times 5.6 \times 22 \frac{6}{7} = 64 [/tex]
