Evaluate the expression (8.1 +7.9)x-(25/5)x

Answer:

x = 10

Step-by-step explanation:

The bigger triangle is 2 times larger than the smaller triangle meaning all of the value of the smaller triangle are 2 times smaller than the bigger triangle and the bigger triangle is 2 times larger than the smaller triangle

Answer:

x = 10

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{x}{5}[/tex] = [tex]\frac{6}{3}[/tex] = 2 ( multiply both sides by 5 )

x = 10

Answer:

The mean is 6.

Step-by-step explanation:

To find the mean you need to do the following.

first, add up all the data to get a total.

next, count the amount of data you have.

lastly, divide the total by the count.

Answer:

6

Step-by-step explanation:

our given database is

2,3,6,6,7,8,8,8

add up all data:

[tex] \displaystyle \rm2 + 3 + 6 + 6+ 7 + 8 + 8 + 8[/tex]

[tex] \displaystyle = 48[/tex]

count the amount of data:

[tex] \displaystyle \boxed{ \begin{array} {ccc} \text{we have two 1 time} \\\text{we have three 1 time} \\ \text{we have six 2 times} \\ \text{we have seven 1 time} \\ \text{we have eight 3 time} \\ \hline \text{total} \quad \quad8\end{array}}[/tex]

divide the total by the count:

[tex] \displaystyle \frac{48}{8} [/tex]

[tex] \displaystyle = 6[/tex]

hence,

the mean of the database is 6

Answer:

30

Step-by-step explanation:

Given that,

No. of pairs of pants = 3

No. of shirts = 5

No. of pairs of shoes = 2

No. of different outfits that Jane can choose from = 3 * 5 * 2

= 30

∵ The maximum number of different outfits would be 30.

Answer:

8

Step-by-step explanation:

take the number of people in the audience and multiply by the percent that have green eyes to determine the number with green eyes

80 * 10 %

Change to decimal form

80 *.10

8

Answer:

so, as given 10% have green eyes,

10% of 80

10/100×80

800/100

=8

so 8 people have green eyes

1. The curve is a parabola with a vertex at (2,1) and is traced from left to right for increasing values of t.

Step-by-step explanation:

1. explanation is in the image

Answer:

A

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

We can use this formula to find the equation of the line

(y-y1)/(y2-y1) = (x-x1)/(x2-x1)

(y - 11)/(23-11) = (x-1)/(3-1)

(y-11)/12 = (x-1)/2

y-11 = 6x-6

y = 6x + 5

the rate of change is the slope of the line, while the constant (5) is the y intercept

Answer:

4 1/11 hours

Step-by-step explanation:

Tom can paint 1/6 of the fence in an hour

Huck can paint 1/5 of the fence in an hour

Tom takes a half-hour break; we can create this equation:

1/6x - 1/2 + 1/5x = 1

use a denominator of 30:

5x/30 - 15/30 + 6x/30 = 30/30

11x/30 = 45/30

multiply each side by 30/11 to get:

x = 45/11 or 4 1/11

Answer:

y=-25x+225

Step-by-step explanation:

The slope is -25 and I think the y-intercept is 225.

Hope this helps.

Reflection rule

Reflection over x axis

Y that was once a positive number, is flipped to a negative

example

6,2 reflected over the x axis.

2=-2

Y axis rule example

-2,7 reflected over the y axis

-2=2

Step-by-step explanation:

If it ever says (example,example) like flipped over the x, it will change the y.

Same for a flip over the y, it will change the x

Answer: the correct answer is A. 35, 55

Step-by-step explanation: got it right on my exam today

35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.

Congruent angles are the angles that have equal measures.

According to the given  question

We have different angles for [tex]sinx[/tex] and  [tex]cosy[/tex].

And we have to find "the pairs of angles which has congruent values for sinx and cosy.

Therefore,

35 degree and 55 degree

sin(35) = [tex]sin(\frac{7\pi }{36})[/tex] =0.57

cos(35) = [tex]cos(\frac{11\pi }{36})[/tex] = 0.57

⇒ 35 degrees and 55 degrees are the pair of angles has congruent values for sinx and cosy.

35 degrees and 70 degrees

sin(35) =[tex]sin(\frac{7\pi }{36} ) =0.57[/tex]

cos(70) =[tex]cos(\frac{7\pi }{18} )[/tex] = 0.34

⇒35 degrees and 70 degrees are the pair of angles have not congruent values for sinx and cosy.

35 degrees and 145 degrees.

sin(35)=[tex]sin(\frac{7\pi }{36} )= 0.57[/tex]

cos(145) = [tex]cos(\frac{29\pi }{36} )= -0.8[/tex]

⇒ 35 degrees and 145 degrees are the pair of angles have not congruent values for the sinx and cox.

35 degrees and 55 degrees

sin(35) =[tex]sin(\frac{7\pi }{36} )[/tex]= 0.57

cos(35) = [tex]\frac{x}{y} =\frac{7\pi }{36} = 0.8[/tex]

⇒ 35 degrees and 55 degrees are the pairs of angles have not congruent values for sinx and cosx.

Hence, 35 degrees and 55 degrees are the pairs of angle have congruent value for sinx and cosx.

Answer:

The value of the mutual force between them is 3.6 x 10⁶ N

Step-by-step explanation:

Given;

distance between the two-point charges, r = 2000 m

the value of the two-point charges, q₁ and q₂ = 40 C and -40 C

Coulomb's constant, k = 9 x 10⁹ Nm²/C²

The value of the mutual force between them is calculated by applying Coulomb's law;

[tex]F = \frac{K|q_1|q_2|}{r^2} \\\\F = \frac{(9 \times 10^9)(40\times 40)}{(2000)^2} \\\\F = 3.6 \times 10^6 \ N[/tex]

Therefore, the value of the mutual force between them is 3.6 x 10⁶ N.

m∡ABC = 135°

Step-by-step explanation:

∡ABE ≅ ∡CBD therefore we can create the following equation:

3x + 27 = 45

3x = 18

x = 6

∡CBD and ∡ABC are supplementary so 180 - ∡CBD = m∡ABC

180 - 45 = m∡ABC

m∡ABC = 135°

Basically, an outlier is a point on a graph that doesn't really fit the pattern.

An outlier can throw off a mean, if the outlier is larger than the other points, it can make the mean much higher than it should be. Vice versa, if it is smaller, the mean is much lower.
