Lorenzo is building a bookshelf. He wants the bookshelf to be 1.5 feet taller than 1/4 the height of his plant stand. If p equals the height of Lorenzo's plant stand, which expression represents the height of the bookshelf?

A. 4p + 1.5
B. 1/4 + 1.5 p
C. p/4 + 1.5
D. 4/p + 1.5

Answer:

Correct Choice: B) 4.7x10^1

Step-by-step explanation:

Scientific Notation

The diameter of a red blood cell is about 0.0008 cm. Expressing in scientific notation, the diameter is [tex]8\cdot 10^{-4} \ cm[/tex].

The diameter of a chickenpox virus is about [tex]1.7\cdot 10^{-5}\ cm[/tex]. It's already expressed in scientific notation.

The ratio of both measures is:

[tex]\displaystyle \frac{8\cdot 10^{-4} \ cm}{1.7\cdot 10^{-5}\ cm}[/tex]

Dividing the coefficients and subtracting the exponents:

[tex]\displaystyle 4.7\cdot 10^{1}[/tex]

Correct Choice: B) 4.7x10^1

Equality Properties

Step-by-step explanation:

Step 1: Define

10 = 5m/4

Step 2: Solve for m

Step 3: Check

Plug in m into the original equation to verify it's a solution.

Here we see that 10 does indeed equal 10.

∴ m = 8 is the solution to the equation.

Answer:

$884.34

Step-by-step explanation:

$850.00*2%=$17.00

$850.00+$17.00=$867.00

$867.00*2%=$17.34

$867.00+$17.34=

$884.34

Answer: $850 x 2 = $1700.00

Step-by-step explanation: You just multiply 2 times $850 and you get your answer.

Answer: I believe the correct answer is the last one but I’m not entirely sure, wait for someone else to answer.

Step-by-step explanation:

Answer:

third one

Step-by-step explanation:

point-slope form is y - y1 = m(x - x1)

plug in values  y -(-5) = 2/3(x - 4)

the double negative cancels out and becomes a positive

therefore y + 5 = 2/3(x - 4)

Answer:

10$ for an adult and 7$ for a child

Step-by-step explanation:

price for an adult = a

price for a child = b

2a + 4b = 48.............(i)

5a + 2b = 64.............(ii)

make a subject of the formula in equation (i)

2a = 48 - 4b

divide through by 2

a = 24 - 2b

Insert the value of a in equation (ii)

5(24 - 2b) + 2b = 64

120  - 10b + 2b = 64

collect like terms

- 8b = 64 - 120

-8b = -56

divide both sides by -8

b = 7

insert the value of b in equation(i)

2a + 4(7) = 48

2a + 28 = 48

2a = 48 - 28

2a = 20

divide both sides by 2

a = 10

The price for one adult is $10 while the price for one child is $7

Answer:

A) [tex]m=8.65h[/tex]

B) $29.58

Step-by-step explanation:

Earnings per hour = $8.65

To find:

A) Write a rule for money m as a function of the number of hours h spent mowing lawns.

Earnings done in one hour = $8.65

Number of hours = [tex]h[/tex]

To find the total earnings, [tex]m[/tex] as a function of number of hours [tex]h[/tex], we need to multiply per hour earnings with number of hours [tex]h[/tex].

Therefore, the equation is:

[tex]m=8.65h[/tex]

B) How much does Robert earn if she works 3 hours and 25 minutes?

First of all, let us convert 3 hours and 25 minutes to hours.

3 hours 25 minutes = 3.42 hours

Therefore, total earnings are:

[tex]m = 8.65\times 3.42 = \$29.58[/tex]

Step-by-step explanation:

C

The theorem that applies is Similar SAS.

The correct option is C.

Those triangles look the same but are different in size.

And in similar triangles,

the corresponding sides are in proportion to each other and the corresponding angles are equal to each other.

Given information:

SM = 27, angle SMA = 31 degrees, MA = 15, DL = 9, LE = 5 and Angle DLE = 31 degrees.

From the given information, we know that angle SMA is congruent to angle DLE because they both have a measure of 31 degrees. However, we do not have any information about the other angles in the two triangles.

To check if the corresponding sides are proportional, we can compare the ratios of the corresponding side lengths:

SM/ DL = 27/9 = 3

MA/LE = 15/5 = 3

Since the ratio of SM to DL is equal to the ratio of MA to LE, we know that the corresponding sides are proportional.

Therefore, we can use the Similarity-SAS (Side-Angle-Side) postulate to conclude that the triangles are similar. The postulate states that if two pairs of corresponding sides are proportional and the included angles are congruent, then the triangles are similar.

The answer is (C) Similar - SAS.

Answer:

Simple!

Step-by-step explanation:

The triangle is obviously a right triangle, meaning, we can use the Pythagorean Theorem to solve for x!

(The Pythagorean Theorem is where [tex]a^2=b^2+c^2[/tex], or the length of the hypotenuse (side opposite to the 90 degree angle) squared is equal to the length of one leg squared plus the other leg squared).

To put it simply:

[tex]x^2=20^2+5^2[/tex]

Now to solve!

[tex]x^2=400+25\\x^2=425\\x=\sqrt{425} \\x=5\sqrt{17}[/tex]

This cannot be simplified further, so that's your answer!

Answer:

2 1/2 meters

Step-by-step explanation:

Amita's kitchen is rectangular with an area of 3 3 /4 square meters. The width of the kitchen is 1 1/ 2 meters. What is the length, in meters, of Amita's kitchen?

The formula for the area of a rectangle = Length × Width.

To find the length our formula becomes : Area/Width

In the question,

Area = 3 3/4 m²

Width = 1 1/2 m

Length of the rectangular kitchen

= 3 3/4 m² ÷ 1 1/2 m

= 15/4 m² ÷ 3/2 m

= 15/4 m² × 2/3 m

= 5/2 m

= 2 1/2 m

The length of the rectangular kitchen is 2 1/2 meters

Answer:

Step-by-step explanation:

Use Pythagorean theorem to get c^2 for the hypotenuse, which is equal to [tex]\sqrt80[/tex]. You then simplify to get the simplest radical form by [tex]\sqrt80[/tex] = [tex]\sqrt{8*10} = \sqrt{4*2*5*2} = \sqrt{16*5} = 4\sqrt{5}[/tex]

Answer:

Step-by-step explanation:

[tex]\frac{x}{420}=\frac{85}{100}[/tex] (The [tex]\frac{85}{100}[/tex] is 85% of the 100% people because 15% is missing)

When you cross-simplify you get: [tex]\frac{x}{21}=\frac{85}{5}[/tex] which is [tex]\frac{x}{21}=17[/tex]

Finally, multiply 17 by 21 to get x.

Therefore, x=357
