find x. round your answer to the nearest tenth

Answer:

Step-by-step explanation:

Answer:

30 cm

Step-by-step explanation:

set up a proportion of insect height over its shadow equals flower height over its shadow, then cross-multiply

1/.5 = x/15

.5x = 15

x = 30

Answer:

2 ducks and 8 goats

Step-by-step explanation:

let goat be g

let duck be d

d + g = 10

ducks have 2 legs, 2d

goats have 4 legs, 4g

2d + 4g = 36

making d the subject in the first equation;

d = 10 - g

put in second equation

2(10 - g) + 4g = 36

20 -2g + 4g = 36

2g = 36 - 20

2g = 16

g = 8

if g is 8

d = 10 - 8

d = 2

Step-by-step explanation:

14. K' = x + a, y + b

= -1 + 2, 6 + 3

K' = 1, 9

K" = (x, y) → (-x, y)

= (1, 9) → (-1, 9)

K" = -1, 9

15. D. Octagon

Since it has 8 angles, of 360 ° is divided by 8 angles, then each corner has an angle of 45 °

16. P' = x + a, y + b

= -2 + 6, 4 + 5

P' = 4, 9

17. H' = x + a, y + b

= 5 + 10, 4 + (-11)

= 15, -7

18. A (6, -1)

A' = (x, y) → (x, -y)

= (6, -1) → (6, -(-1)

= 6, 1

19. J' = x + a, y + b

= -2 + (-3), 1 + (-3)

= -5, -2

J" = (x, y) → (x, -y)

= (-5, -2) → (-5, -(2))

= -5, -2

Answer:

Answer:

The equations are:

[tex]m^2 = p^2 + z^2[/tex]     [tex]m^2 = z^2 + p^2[/tex]

[tex]z^2 + p^2 = m^2[/tex]     [tex]p^2 + z^2 = m^2[/tex]

Step-by-step explanation:

Given

See attachment for triangle

Required

Select all true equations

From the attachment:

[tex]m = hypotenuse[/tex]

[tex]p\ and\ z = other\ legs[/tex]

Using Pythagoras theorem:

[tex]m^2 = p^2 + z^2[/tex]

This can be rewritten as:

[tex]m^2 = z^2 + p^2[/tex]

or

[tex]z^2 + p^2 = m^2[/tex]

or

[tex]p^2 + z^2 = m^2[/tex]

Answer:

3x^2-4x+12

Step-by-step explanation:

x(2x+3)+(x-3)(x-4)

2x^2+3x+x^2-3x-4x+12

2x^2+x^2+3x-3x-4x+12

3x^2-4x+12

Answer:

3x² -4x + 12

Step-by-step explanation:

x(2x + 3) + (x - 3)(x - 4)

= 2x² + 3x + x² - 4x -3x + 12

= 3x² -4x + 12

Answer:

i think the answer is

-4x+48

Answer:

Multiply the first equation by 2

2(2x+y=5) to get 4x + 2y = 10

add the second equation 3x-2y=4

4x + 3x + 2y + -2y = 10 + 4

7x = 14

x = 2

...

Multiply the first equation by 3 and the second equation by -2 then add

3(2x+y=5) to get 6x + 3y = 15

-2(3x-2y=4) to get -6x + 4y = -8

add them

6x + -6x + 3y + 4y = 15 + -8

7y = 7

y = 1

...

x = 2 , y = 1

(2, 1) is the solution

...

check

2(2) + 1 = 5

4 + 1 = 5

5 = 5

Correct

Answer:

g(x) = (x -3 )^2 + 2

Step-by-step explanation:

f(x) = (x + 2)^2 + 2

We want to shift this 5 units to the right

The parabola is written in the form

y = a(x-h) ^2 +k  where (h,k) is the vertex

The vertex is at ( -2, 2)

We want to shift it 5 units to the right

-2+5 = 3

g(x) = (x -3 )^2 + 2

Answer:

g'(x) = (x-3)² + 2

Step-by-step explanation:

g'(x) = (x+2 - 5)² + 2

Answer:

x = 37.5

Step-by-step explanation:

By Basic Proportionality Theorem:

[tex] \frac{x}{20} = \frac{46 - 16}{16} \\ \\ \frac{x}{20} = \frac{30}{16} \\ \\ x = \frac{20 \times 30}{16} \\ \\ x = \frac{600}{16} \\ \\ x = 37.5[/tex]

Answer:

The answer is no because 5 is greater than 3

Step-by-step explanation:

Given

375 = 15 c

c = 375 / 15

c = 25

Answer:

3 1/3 metric tons per hour

Step-by-step explanation:

To find the unit rate, divide 3 3/4 metric tons by 1 1/8 hours (notice that the correct format is 3 3/4, not 3/3/4).

 3 3/4 metric tons       3.75 metric tons

---------------------------- = --------------------------

        1 1/8 hours                1.125 hours

It's easier to deal with decimal fractions here than with proper fractions.

The unit rate then comes out to be 3.75/1.125 metric tons per hour, or

3.33333 metric tons per hour, or   3 1/3 metric tons per hour

Answer:

Step 1: multiply

10*10=100*10=1000*10=10000

Step 2: write 1st one out.

(8*10000)

Step 3: multiply

8*10000=80000

________________-

Step 1: multiply

10*10=100*10=1000*10=10000*10=100000*10=1000000*10=10000000*10=100000000*10=1000000000*10=10000000000*10=100000000000*10=1000000000000

step2: multiply

2*100000000000=200000000000

step 3: write it out

80000*200000000000

step 4: solve

80000*200000000000=1.6 to the power of 17

Answer:

A proportion is a comparison of two numbers that each represent the parts of a whole. Essentially, a proportion says that two fractions are the same, even if the amount is different. For example, 1/2 of 10 marbles is the same proportion as 1/2 of 50 marbles.
