Similar triangles may or may not be congruent

The value of x that makes both triangles similar is 4.5

The equivalent ratio of both triangles is:

[tex]\mathbf{2 : 1 = 9 : x}[/tex]

Express the above equivalent ratio as a fraction

[tex]\mathbf{\frac 12= \frac x9 }[/tex]

Multiply both sides of the fraction by 9

[tex]\mathbf{\frac 12\times 9 = \frac x9 \times 9 }[/tex]

Cancel out common factors

[tex]\mathbf{\frac 12\times 9 = x}[/tex]

Divide 12 by 9

[tex]\mathbf{4.5 = x}[/tex]

Rewrite the above expression as:

[tex]\mathbf{x = 4.5 }[/tex]

Hence, the value of x is 4.5

Answer:

2 hours or lower

Step-by-step explanation:

$13 + $5t = fee

13 + 15t = 43 --> minus 13 on both sides

15t = 30 --> divide by 15 on both sides

t = 2

Answer: t=6

Explanation:

They want to spend less than $43, 43-13=30 and 30/5=6, Therefore they could have 6 hours max, if the initial reservation fee is $13 and and additional $5 per hour.

ANSWER:

1 : 14

EXPLANATION:

1)  Convert 1 meter to centimeters.

7 cm : 100 cm

2) Now you just simplify both sides (divide 7 by 7 to get 1 and then you have to divide 100 by 7 as well).

[tex]\frac{7}{7}=1[/tex]

[tex]\frac{100}{7}=14.285[/tex]

Therefore, the ratio is:

1 : 14

Answer:

Felisha

Step-by-step explanation:

Rewrite the equation as

2lw+2lh+2wh=a.2lw+2lh+2wh=a

Subtract

2lh

from both sides of the equation.

2lw+2wh=a−2lh

Factor

2w out of 2lw+2wh.

2w(|+h)=w−2lh

Divide each term by

2(l+h)

and simplify.

.w=a−2lh2(l+h)

Answer:

  31 2/3

Step-by-step explanation:

No doubt you have been shown at least a couple of different strategies for multiplying mixed numbers.

1) Use the distributive property.

  10(3 1/6) = 10(3) +10(1/6) = 30 +10/6 = 30 +5/3 = 30 + 1 2/3 = 31 2/3

__

2) Use improper fractions.

  10(3 1/6) = 10(19/6) = 190/6 = 95/3 = 31 2/3

Answer:

  f^-1(x) = (x +6)/2

Step-by-step explanation:

The inverse function is found by solving ...
