First you ask yourself, can 8 go into 1? The answer is no. Can 8 go into 12? Yes, 1 time. So you put 1 on top of the 2 and subtract 8 from 12. That gives you 4. Then you pull down the 8 from 128 and ask how many times can 8 go into 48? The answer is 6. So your answer is 16. Hope I helped!

You can divide 128 by 8 and it would equal 16

1.In a right triangle, <A and <B are acute. Find the value of csc A, when tan A = 8/15.

bekas [8.4K]

Answer:

(1) $csc A=\dfrac{17}{8}$

(2) $sec A=\dfrac{17}{15}$

Step-by-step explanation:

$Tan A=\dfrac{8}{15}\\$In Trigonometry, $Tan A=\dfrac{Opposite}{Adjacent}\\$Therefore:\\Opposite=8, Adjacent=15$

Using Pythagoras theorem

$Hypotenuse^2=Opposite^2+Adjacent^2\\Hypotenuse^2=8^2+15^2\\Hypotenuse^2=289\\Hypotenuse^2=17^2\\Hypotenuse=17$

Question 1

Now, cosecant = 1/sin

Therefore:

$csc A=\dfrac{Hypotenuse}{Opposite}\\csc A=\dfrac{17}{8}$

Question 2

Now, secant = 1/cos

Therefore:

$sec A=\dfrac{Hypotenuse}{Adjacent}\\sec A=\dfrac{17}{15}$

A company is giving gifts to its employees. Employees can choose a gift card, hat, or candy. The table shows the gift chosen by

Paraphin [41]

Answer:

360 Employees

Step-by-step explanation:

Number of employees who chose gift card / Number of total employees

= 90 / 150

Now, we have to figure out in x / 600 when the x represents the number of employees choosing gift card when there are 600 employees in total.

90 / 150, x / 600

-> cross multiply

54,000 = 150x

Therefore 360 = x.

another way:

(multiply the total number of employees in both ratios) 600 / 150 = 4

Now we multiply 4 by 90 (number of employees choosing gift card)

4*90 = 360

Mumz [18]

Question is incomplete, here is the complete question below:

Three students were given the expression shown and were asked to take a common factor out of two of the terms.

Use the drop-down menus to complete the statements about whether each student's answer is an equivalent expression. Then choose an expression that is equivalent.

7-8x+22

Calvin: 7−2(4x+11)

Calvin's expression is (correct/incorrect) because .............

Greg: 7+14x

Greg's expression is (correct/incorrect) because ............

Ruben: 7+2(4x+11)

Ruben's expression is (correct/incorrect) because .

Equivalent Expression

The correct simplification of this expression is ...............

Answer:

The correct simplification of this expression is 7-2(4x-11)

Step-by-step explanation:

Calvin: 7−2(4x+11)

Calvin's expression is incorrect because if -2 is taken as common term then sign (+) should also be changed to (-)

i.e. 7−2(4x+11) produces 7-8x-22 which is not equivalent to 7-8x+22

Greg: 7+14x

Greg's expression is incorrect because 7+14x is not equivalent to 7-8x+22

Ruben: 7+2(4x+11)

Ruben's expression is incorrect because 7+2(4x+11) =7+8x+22 which is not equivalent to 7-8x+22

Equivalent Expression is 7-2(4x-11)

The correct simplification of this expression is 7-2(4x-11)
