I think that the right answer is $5 because if he want 4 toppings, that would be 0.75+0.75+0.75+0.75 which is 3 and ten you do 2+3=$5

Kailey wrote 8,912,000 in scientific notation as 89.12 times 10 Superscript 5. Which statement best describes Kailey's work? Kai

hodyreva [135]

Answer:

D. Kailey is not correct: $89.12 \times 10^5$ is not written in scientific notation.

Step-by-step explanation:

We have been given that Kailey wrote 8,912,000 in scientific notation as $89.12 \times 10^5$ . We are asked to choose the statement that best describes Kailey's work.

We know that to convert a number into scientific notation, we write the given number as product of two numbers. One factor is a number between 1 and 10, while the 2nd factor is power of 10.

Upon looking at $89.12 \times 10^5$ , we can see that 1st factor is 89.10, which is greater than 10. This means that Kailey did not write 8,912,000 in scientific notation.

Therefore, option D is correct choice.

What is the height of the building pictured below if its shadow is 100 ft. long?

Evgen [1.6K]

Yeah.. baby, do the SOH CAH TOA with the hula hoop

$\bf 
sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}
$

so.. hmmm we have in the picture, an angle, and two sides,
actually, is the "adjacent" side, and the "opposite"

so.. which of those ratios give us only
the angle
the adjacent side
the opposite side?

ahhha!, is Ms tangent
so $\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(42^o)=\cfrac{h}{100}$

solve for "h"

PLEASE HURRY!! CIRCUMFERENCE AND PIRIMITER APPLICATIONS question Don't mind the answer I put I didn't mean to click it... thank

Option C:

Perimeter of the $\frac{1}{4}$ of a circle = 10.71 cm

Solution:

Given figure is $\frac{1}{4}$ of a circle.

It is a quarter of a circle.

Radius = 3 cm, Value of π = 3.14

To find the perimeter of the quarter of a circle.

Perimeter of the quarter of a circle formula: $$\frac{\pi r}{2}+2r$

$\text {Perimeter} =\frac{\pi r}{2}+2r$

$=\frac{3.14\times3}{2}+2\times3$

$=4.71+6$

$=10.71$

Perimeter of the quarter of a circle = 10.71 cm

Option C: 10.7 is the correct answer.

Hence perimeter of the $\frac{1}{4}$ of a circle is 10.71 cm.

An oil drilling company drills the same distance each day for 5 days. They started at an elevation of 121.175 feet and ended at

nirvana33 [79]

Answer:

$x=\dfrac{|-246.875-121.175|}{5}$

Step-by-step explanation:

Given that:

Same distance is drilled by the oil drilling company for 5 days.

Initial elevation = 121.175 feet

Final elevation = -246.875 feet

To find:

The equation to find the value of $x$ i.e. the distance drilled each day?

Solution:

To find the distance drilled each day, we need to divide the total distance drilled with the number of days taken to drill the total distance.

Total distance drilled can be found by subtracting the initial elevation from the final elevation and taking modulus because distance can not be negative.

Total distance drilled = | Final elevation - Initial elevation |

Total distance drilled = | -246.875 - 121.175 |

Therefore, we can write the expression as:

$x=\dfrac{|-246.875-121.175|}{5}$

$\Rightarrow x=\dfrac{|-368.05 |}{5} =73.61\ ft/day$
