Answer:

84.05 square inches

Step-by-step explanation:

Given;

Area of M = 320 square inches

Scale factor of M to N = 8 : 4.1

Since M and N are equilateral, it means all 3 sides in triangle M are equal and all 3 sides in triangle N are equal

To find the area of triangle N, we have:

$N = 320 * (\frac{4.1}{8})^2$

= 84.05 square inches

Therefore area of triangle N =

84.05 square inches

The equation x° = 180° - (37°+ 53°) can be used to find the value of x.

Step-by-step explanation:

Step 1; There are three lines in the given diagram. There are a baseline and two other lines. Out of the other two lines, one extends above and below the baseline whereas the other extends only above. Since the baseline is horizontal and the others are at angles we have the sum of all the three angles as 180° i.e. 37°, x°, and 53°.

37° + x° + 53° = 180°.

Step 2; To solve the value of x, we keep the unknown value at the left-hand side whereas all the known values are taken to the right side of the equation.

x° = 180° - (37°+ 53°).

So the fifth option can be used to determine the value of x.

The average time an individual reads online national news reports is 49 minutes. Assume the standard deviation is 16 minutes and

Olin [163]

Answer:

0.118 is the probability someone will spend no more than 30 minutes reading online national news reports.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 49 minutes

Standard Deviation, σ = 16 minutes

We are given that the distribution of time an individual reads is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(no more than 30 minutes)

$P( x \leq 610) = P( z \leq \displaystyle\frac{30 - 49}{16}) = P(z \leq -1.1875)$

Calculation the value from standard normal z table, we have,

$P(x \leq 30) = 0.118 = 11.8\%$

0.118 is the probability someone will spend no more than 30 minutes reading online national news reports.

Angelina_Jolie [31]

Since we are asked for tge graph that represent the total cost for the x numbers of lesson, it will be helpful to illustrate it first this way

for each lesson it will cost $30 dollars

1 lesson $30

2 lessons $60

3 lessons $90

4 lessons $120

5 lessons $150

So from this set of numbers , it is apparent that the grqph in letter c represents the total costs for x numbers of lessonsseethati

What is the answer for this

Eva8 [605]

1). 2x-1=5 (cause x can really be anything) solve the equation to get x=3 or in this case, triangle = 3.

2). Using the info from above, we get the equation 3+x=1.
Solving this equation we get, x (square) =-2.

3). Using all the info from the above problems we get the equation: 3-2*-2=x
Solving that we see that x (star) equals 7.

In conclusion:

Triangle=3
Square=-2
Star=7
