Answer:

True!

Step-by-step explanation:

They both are the same shape just the scale size changed! They are the same because 6 ÷ 4 = 1.5 and 3 ÷ 2 = 1.5. Pls Brainliest! ;) It would mean a lot!

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

At first glance I would say that they are similar but when you look at the proportions of this triangle you could tell that they aren't at all proportional so that makes them not similar to each other at all.

Answer:

y=3/2x-5

when finding the equation of a line, we use this formula

y=mx+b

where Y= a point on the y-axis

M= ∆y/∆x

x= a point on the x-axis

and b = intercept

Step-by-step explanation:

so to in this case, we are given y= 4, x=6 and y-int = -5

substitute the value in the given equation,

therefore, 4=6m-5

4+5=6m

9/6=M

3/2=m

Answer y=3/2x-5 that is the equation of the line

Answer:

65

Step-by-step explanation:

Answer:

f = 65

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

201.5 = f + 136.5

Step 2: Flip the equation.

f + 136.5 = 201.5

Step 3: Subtract 136.5 from both sides.

f + 136.5 − 136.5 = 201.5 − 136.5

f = 65

Answer:

Alana bought 4 cans of paint additive

Step-by-step explanation:

Proportions

If a proportional amount of x is to be distributed between y elements, each one of them gets x/y portions.

For example, if we have 100 coins and distribute evenly between 20 boxes, each box will receive 100/20=5 coins.

Alana bought 1/2 of a liter of the special paint additive and evenly distributed it between an unknown number of cans, let's call it C. We also know each can received 1/8 of a liter of the additive. That is the proportion of the 1/2 liter of additive.

We can establish the following condition:

[tex]\displaystyle \frac{1/2}{x}=\frac{1}{8}[/tex]

Solving for x:

[tex]\displaystyle \frac{1/2}{\frac{1}{8}}=x[/tex]

Transform the division into a product:

[tex]\displaystyle x=\frac{1}{2}\cdot\frac{8}{1}=4[/tex]

Answer:

not a polynomial

Step-by-step explanation:

A polynomial is a combination of terms separated by + or − signs. A polynomial does not contain variables raised to negative or fractional exponents, variables in the denominator or under a radical, or any special features such as trigonometric functions, or logarithms

Answer:

False is a Non-polynomial

Answer:

The coordinates of point S are (5, 9) will make line PQ // line RS ⇒ A

Step-by-step explanation:

Parallel lines have  the same slopes

The slope of a line = Δy/Δx, where

Let us first find the slope of the line PQ.

∵ P = (-2, -2) and Q = (0, 7)

∴ Δx = 0 - (-2) = 0 + 2 = 2

∴ Δy = 7 - (-2) = 7 + 2 = 9

∴ The slope of PQ = 9/2

∵ Line PQ // line RS

∴ The slope of line PQ = the slope of line RS

∴ The slope of line RS =9/2

∵ Point R = (3, 0) and point S = (x, y)

∵ The slope of line RS = 9/2

∵ The slope = Δy/Δx

∴ Δy/Δx = 9/2

→ That means Δy = 9 and Δx = 2

∵ Δy = y - 0

∵ Δy = 9

∴ 9 = y

∵ Δx = x - 3

∵ Δx = 2

∴ 2 = x - 3

→ Add 3 to both sides

∴ 2 + 3 = x - 3 + 3

∴ 5 = x

∴ The coordinates of point S are (5, 9) will make line PQ // line RS

Answer: 4 1/4 hours

Step-by-step explanation:

Answer:

it will take 4 hours and 30 minutes

Step-by-step explanation:

first you have to divide 4 by 17 so you would get 4 with a remainder of one. Next, four will be the number of hours and  the 1 is the 30 minutes.

Answer:

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Step-by-step explanation:

To get the temperature at a mountain base camp on Friday evening, we must translate statement into a mathematical form:

(i) The temperature at a moutain base camp was - 2 degress Celsius on Thursday:

[tex]T_{o} = -2\,^{\circ}C[/tex]

(ii) Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday:

[tex]\Delta T_{1} = -1\,^{\circ}C[/tex]

(iii) Friday evening, the temperature was 3 degrees Celsius lower that it was that morning:

[tex]\Delta T_{2} = -3\,^{\circ}C[/tex]

The temperature at the base camp Friday evening is:

[tex]T = T_{o}+\Delta T_{1}+\Delta T_{2}[/tex]

[tex]T = -2\,^{\circ}C-1\,^{\circ}C-3\,^{\circ}C[/tex]

[tex]T = -6\,^{\circ}C[/tex]

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Answer:

D) -6 degrees Celsius

Step-by-step explanation:

Answer:

B. Rectangle T, Rectangle P, Rectangle S.

Step-by-step explanation:

To determine which list shows the correct order of the length of the diagonals of the rectangles from shortest to longest, let all the lengths be in decimal form:

Rectangle P = 6.7 cm

Rectangle S = [tex] \frac{34}{5} cm [/tex] = 6.8 cm

Rectangle T = [tex] \sqrt{36.5} cm [/tex] ≈ 6.04

Thus:

6.04 cm < 6.7 cm < 6.8 cm

Therefore, from the shortest to the longest, we have:

Rectangle T < Rectangle P < Rectangle S.

Answer:

The probability that the sample mean would differ from the population mean by greater than 2.4 gallons is 0.86558

Step-by-step explanation:

The given parameters are;

The mean, [tex]\bar x[/tex] = 101 gallons

The population mean = μ

The variance, σ² = 49

The number of racing cars, n = 43

The probability that the sample mean would differ from the population mean by greater than 2.4 gallons is given as follows;

P([tex]\left | \bar x - \mu \right |[/tex]) >2.4 = P(2.4 > [tex]\left | \bar x - \mu \right |[/tex] >-2.4)

The formula for the test of the mean, Z₀, is given as follows;

[tex]Z_0 = \dfrac{\bar x - \mu}{\dfrac{\sigma}{\sqrt{n} } }[/tex]

Therefore, we have;

[tex]P \left (\dfrac{2.4}{\dfrac{\sqrt{49} }{\sqrt{43} } } >Z> \dfrac{-2.4}{\dfrac{\sqrt{49} } {\sqrt{43} } } \right) = P \left (\dfrac{2.4}{\dfrac{7 }{\sqrt{43} } } >Z> \dfrac{-2.4}{\dfrac{7} {\sqrt{43} } } \right)[/tex]

Which gives;

P([tex]\left | \bar x - \mu \right |[/tex]) >2.4 = P(2.25 > Z > -2.25)

(We round up to 2.25 because that is the accuracy of the z-table)

From which we have;

P(Z > -2.25) - P(Z > 2.25) = (1 - P(Z < -2.25)) -  (1 - P(Z < 2.25))

P([tex]\left | \bar x - \mu \right |[/tex]) >2.4 =  (1 - 0.1222) - (1 - 0.98778) = 0.86558

The probability that the sample mean would differ from the population mean by greater than 2.4 gallons = 0.86558.

Answer:

[tex]d = 15.620499[/tex]

Step-by-step explanation:

To solve this question, we must use the following distance equation:

[tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]

Plug your coordinates into the equation. Remember, a coordinate is denoted as (x, y).

[tex]\sqrt{(12-2)^{2} + (13-1)^{2}}[/tex]

[tex]\sqrt{(10)^{2} + (12)^{2}}[/tex]

[tex]\sqrt{100+144}[/tex]

[tex]\sqrt{244} = 15.620499[/tex]
