The difference of 7 and the square of a number

Answer:

b

Step-by-step explanation:

I had that question before

Answer:

Step-by-step explanation:

a) Side ratios in the smaller triangle are 3:4:6. In the larger triangle, they are 5:6:9. These are not equivalent ratios, so the triangles are not similar.

__

b) The missing angle in the left triangle is 90° -55° = 35°. This matches the acute angle shown in the right triangle, so the right triangles are similar by the AA similarity criterion. The given triangle JKL starts with the largest acute angle, then the right angle, so the similarity statement must be ...

  ΔJKL ~ ΔHIG

__

c) All we know for sure is that the vertical angles are congruent. We need information about a pair of sides or of another angle before any similarity can be claimed. The triangles are not necessarily similar.

Answer:

56

Step-by-step explanation:

54 + 4(3/4 − 1/2)2

=> 54 + 4(1/4)2

=> 54 + (1)2

=> 54 + 2

=> 56

Therefore, 56 is our answer.

Answer:

18

Step-by-step explanation:

There are 18 girls on the team this year.

If you take 20 and divide the number by 10 you will get 2.

10%=2

If you multiply 2x10 you get 20.

20-2=18

Answer: The other two values are 3 and 4. This is because it is the only value which fits the formula a^2 + b^2 = c^2 (which will be 5^2 in our case). Also 3,4, and 5 is a well known right angle side length.

Based on the number of cookies in the jar and the number eaten by the person, the number of cookies remaining is 38 cookies.

The total number of chocolate cookies is:

= Total cookies x Percentage that is chocolate

= 40 x 1/5

= 8 cookies

Someone eats 1/4 of this which is:

= 8 x 1/4

= 2 cookies

The number of cookies left is:

= Number of cookies - Number of cookies eaten

= 40 - 2

= 38 cookies

In conclusion, there are 38 cookies remaining.

The proportional equation representing the area Felicia covered, y, in terms of the number of tiles she used, x is:

[tex]y = \frac{x}{6}[/tex].

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

Researching this problem on the internet, we have that 6 tiles cover 1 square feet, 12 tiles cover 2 square feet, and so on, hence the constant is given as follows:

[tex]k = \frac{1}{6} = \frac{2}{12}[/tex]

Hence the function is given as follows:

[tex]y = \frac{x}{6}[/tex].

(-13, -6), (7, 15) = 1.05

Equation: y = 1.05x + 7.65.

The entered points belong to an increasing, linear function.

Answer:

m = rise / run = 21/20, or m = 1.05

Step-by-step explanation:

If the lines are parallel, their slopes are identical.  So we can find the slope of line 1 and know that it's also the slope of line 2.

From (-13, -6) to (7, 15), the x-component increases by 20 units from -13 to 7.  Thus, the "run" in m = rise / run is 20.  Likewise, the "rise" is 21.

Thus the slope in question is m = rise / run = 21/20
