Answer:

[tex]y=-\frac{1}{5} -7.[/tex]

Step-by-step explanation:

1) the rule: if two lines are y=k₁x+b₁ and y=k₂x+b₂ are perpendicular, then k₁*k₂=-1;

2) according to the rule above, the correct answer is y= -1/5 x-7.

Answer:

a) [tex]1\frac{1}{4}[/tex]

b) [tex]46.69[/tex]

Step-by-step explanation:

a) To evaluate the value of this long expression, we can split it up into parts that are easy to calculate. [tex]2\frac{1}{3}+\frac{1}{2}-\frac{1}{12}[/tex] is equal to [tex]2+\frac{4}{12}+\frac{6}{12}-\frac{1}{12}[/tex] and since the fractions have the same denominators, you can add the numerators and keep the denominators. This would result in [tex]2\frac{9}{12}[/tex], which is [tex]2\frac{3}{4}[/tex] simplified. So, now we know that the first parentheses are equal to [tex]2\frac{3}{4}[/tex]. Next, we have to calculate [tex]2(\frac{1}{3}+\frac{1}{4})[/tex]. Using the distributive property to expand, we reach [tex]\frac{2}{3}+\frac{2}{4}[/tex] and we bring them both with a denominator of 12 and add to get [tex]\frac{7}{6}[/tex]. Finally, the last square root is equal to [tex]\frac{1}{3}[/tex] because [tex](\frac{1}{3})^2[/tex] is equal to [tex]\frac{1}{9}[/tex]. To find our final answer we put all of our answers together in the expression [tex]2\frac{3}{4}-\frac{7}{6}-\frac{1}{3}[/tex]. Bring all of these fractions to a denominator of 12 to get: [tex]2\frac{9}{12}-\frac{14}{12}-\frac{4}{12}[/tex]. We combine to get [tex]1\frac{1}{4}[/tex].

b) Similar to the previous part, we can split this expression into two parts to make it more manageable; [tex]-4.9(-12+\sqrt{0.81})[/tex] and [tex](2.2)^2*1.59[/tex]. Once we find the value of each, we will get our final answer by subtracting the second from the first (as shown in the expression). [tex]-4.9(-12+\sqrt{0.81})[/tex] is equal to [tex]-4.9(-12+0.9)[/tex] which is [tex]-4.9*-11.1[/tex] which is [tex]54.39[/tex]. [tex](-2.2)^2*1.59[/tex] is equal to [tex]4.84*1.59[/tex] which is [tex]7.6956[/tex]. To get the final answer, we do [tex]54.39-7.6956[/tex] which is [tex]46.6944[/tex]. Rounded to the nearest hundredth, it is [tex]46.69[/tex].

Hope this helps :)

Answer:

Step-by-step explanation:

Hi!

These can be set up as systems of equations.

Let b = the number of birds, and let d = the number of dogs.

b + d = 21

2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)

You can solve this using either elimination or substitution.

Answer:

I agree with cristafers work

Step-by-step explanation:

The new coordinates of S' will be located at (1, 8)  after translating 4 units right and 2 units down.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.

For example, If shift up by 1 unit,  add 1 to the function

If shift down by 4 units, subtract 4 from the function

Given that Δ RTS has a vertices R (10,0) S (3,4) And T(4,2)

The original coordinate of S is (3,4).

To determine the image of S' after a vertical transition two units down and a horizontal transition of four units to the right

The y-coordinate will increase by 4 if we move it to the right.

This will then become 4+4 =8.

If we shift it downward, it will become negative and read as -2.

This will then become 3-2 = 1.

So, the coordinate of S' will be located at (1, 8)

Hence, the new coordinates of S' will be located at (1, 8)  after translating 4 units right and 2 units down.

Answer:

(a). 0.0678.

(b). 0.01356

(c). 11.1

(d). 33.3

Step-by-step explanation:

So, we are given the following data or parameters that is going to help us or assist us in solving this particular problem or Question.

(1). We are given from the question that the archer to hit a bull’s-eye, the probability will be 0.09.

(2). "the results of different attempts can be taken to be independent of each other".

Therefore, let us delve right into the solution to the question.

(a). The probability that the first bull’s-eye is scored with the fourth arrow = P(a= 4) = P × ( 1 - P)^a -1.

P(a = 4) = 0.09 × (1 - 0.09) ^4 - 1.

P(a= 4) = 0.0678.

(b). The probability that the third bull’s-eye is scored with the tenth arrow = P(b= 10, y = 3).

P(b= 10, y = 3) = 36 (0.91)^7 × ( 0.09)^3 = 0.01356.

(c). The expected number of arrows shot before the first bull’s-eye is scored = 1/0.09 = 11.1.

(d). The expected number of arrows shot before the third bull’s-eye is scored = 3/0.09 = 33.3.

The rectangles are similar to DEFG and VWXY

We have given the rectangle ABCD, QRSP, EFGD, and WXYV.

We have the rectangle DEFG and WXVY.

A rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.

If we divide WV by 2 and VY by 2 then we get the side ED and DG

Therefore the given two rectangles are similar.

The rectangles are similar to DEFG and VWXY.

Use the distance formula to determine the distance between two points.

Answer:

6 squared feet

Step-by-step explanation:

The formula is  b X h

so we can see that the base is 8 and the height is 3/4

so now the equation would be

8 x 3/4 which is equal to 6

so the area of this parallelogram is 6

Solve:

A. 70+10=80

B. 60+10=70

C. 50+15=65

D. 60+15=75, so D is correct.

Answer:

4 Quarters and 11 Dimes

Step-by-step explanation:

In the first equation, we know that [tex]D=15-Q[/tex] If we plug this into the second equation, we get 25q+10(15-Q)=210. If we simplify this equation, we get 25q+150-10q=210, which can be simplified to 15q+150=210. And since 15q=60, q=4. Then, you subtract 4 from 15, to get 11 dimes. So, there are 4 quarters and 11 dimes. Hopefully, this helps!

Hey there!

To find the number that's one-fourth of 360, we should just divide 360 by 4 and get 90.

There's also another way - multiplying fractions.

[tex]\bold{\displaystyle\frac{1}{4} *\frac{360}{1}}[/tex]

In order to multiply fractions, we just multiply the numerator of one fraction times the numerator of the other one; same with the denominator.

Look what happens when I multiply:

[tex]\bold{\displaystyle\frac{360}{4}}[/tex]

We can use mental maths to solve it.

Hence, the answer's 90.

Hope everything is clear.

Answer:

x = 15

Step-by-step explanation:

We can see that the angle with a measure of 37° and the angle with (9x + 8)° form a straight line, so they add up to 180°. This means that 37 + 9x + 8 = 180.

Step 1: Combine like terms.

Step 2: Subtract 45 from both sides.

Step 3: Divide both sides by 9.

Therefore, x = 15!
