Answer:

h = 2.7 m

Step-by-step explanation:

The larger triangle and the smaller triangle are similar so ratios of corresponding sides are equal, that is

[tex]\frac{6}{6+12}[/tex] = [tex]\frac{0.9}{h}[/tex] , that is

[tex]\frac{6}{18}[/tex] = [tex]\frac{0.9}{h}[/tex] ( cross- multiply )

6h = 16.2 ( divide both sides by 6 )

h = 2.7 m

Gabriella made 5% of her free throws over the season. If she shot 180 free throws, how
many did she miss?

Answers

5% made means that out of every 100 shots she made 5 and therefore she missed 95 of them. You divide 95 by 100. To get percentage of missed shots in decimal form. It would be 0.95. Then multiply by the number of shots she took. Your answer would be 0.95 x 180

A person on a moving sidewalk travels 72 feet in 9 seconds. The moving sidewalk has a length of 240 feet. How long will it take to move from one end to the other?

Answers

Answer:

30 seconds

Step-by-step explanation:

Speed of person :

72 feets in 9 seconds

Distance = 72 feets ; time = 9 seconds

Speed = distance / time

Speed = 72 / 9 = 8 ft/s

Length of sidewalk = 240 feets

Time it takes to move from one end to the other :

Time = distance / speed

Time = 240 feets / 8 feets /sec

Time taken = 30 seconds

Lisa is going on a 3 3/4 mile hike. She has already hiked 1 1/4 miles. How many more miles does she have left to hike?

Answers

Answer:

C = 2½ miles.

Step-by-step explanation:

Let the total distance be A

Let the distance covered be B.

Let the unknown distance (distance left) be C.

Given the following data;

A = 3¾ miles

B = 1¼ miles

To find the distance left to hike;

A = B + C

Substituting into the equation, we have;

3¾ = 1¼ + C

C = 3¾ - 1¼

C = (3 - 1) ¾ - ¼

C = 2 2/4

C = 2½ miles.

Method II.

We would convert the mixed fraction into a proper fraction:

A = 3¾ = (4*3 + 3)/4 = 15/4

B = 1¼ = (4*1 + 1)/4 = 5/4

C = 15/4 - 5/4

C = 10/4

C = 5/2

C = 2½ miles.

Is -6.743743… a rational or irrational number?

Your answer:

Rational because .743 repeats


Rational because the 6 is negative


Irrational because the number never ends


Irrational because the 6 is negative

Answers

It's rational because it contains a repeating digit pattern, 743 (first option).

In particular, if

x = -6.743743…,

then

1000x = -6,743.743743… .

Subtracting, we can eliminate the trailing end and solve for x exactly:

1000x - x = -6,743.743743… - (-6.743743…)

999x = -6,737

x = -6,737/999

What is the Y-Intercept of this table?

[tex]\left[\begin{array}{ccc}x&y\\5&16\\6&19\\7&22\end{array}\right][/tex]

Answers

The Y-Intercept would be on +4.

Answer:

The Y-intercept is 4 or (0,4) in a plot

Step-by-step explanation:

To find the Y-intercept you need to make the "x" zero so if you move 5 to 4 in the "x" plot you need to move 16 to 13

(Since 22 to 19 is -3 19 to 16 is -3 as well it is safe to say that the next number is 13)

Now continue until you reach 0 in the "x"

4 to 3 and 13 to 10

3 to 2 and 10 to 7

2 to 1 and 7 to 4

So the y-intercept is 4 or (0,4) in a plot

To find:

The value of x.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

Using this formula in the given triangle, we get

[tex]\tan (31^\circ)=\dfrac{x}{33}[/tex]

[tex]0.60086=\dfrac{x}{33}[/tex]

[tex]0.60086\times 33=x[/tex]

[tex]19.82838=x[/tex]

[tex]x\approx 19.83[/tex]

Therefore, the value of x is about 19.83 units.

Answers

Answer:

519 meters square

Step-by-step explanation:

16 x 16 = 256

256 / 2 = 128

11.5 + 34 = 391

128 + 391

100 + 300 = 400

20 + 90 = 110

8 + 1 = 9

400 + 110 + 9 = 519

Answer:

I believe the answer is 519m

Step-by-step explanation:

first you seperate the triangle from the rectangle then solve the area for the rectangle 11.5•34=319  then solve the area for the triangle 16•16=256    

256÷2=128    then add 128+391= 519     i hoped this helped you :-)
