A worker bee has a mass of 0.00011 \text{ kg}0.00011 kg0, point, 00011, start text, space, k, g, end text.

xenn [34]

Answer:

Answer:

1). Option (A)

2). Option (A)

Step-by-step explanation:

1). A worker bee has the mass = 0.00011 kg

In scientific notation we can convert the mass of bee as,

0.00011 =

Since 1.1 ≈ 1,

Therefore, 1.1 × 10⁻⁴ ≈ 1 × 10⁻⁴ kg

Option (A) is the answer.

2). An African elephant has a mass = 8139 kg

In scientific notation,

8139 = 8.139 × 10³

Since, 8.139 ≈ 8

Therefore, 8139 kg = 8.139 × 10³ kg

Option (A) is the answer.

Simplify: -3(-5) - 16

sukhopar [10]

The operation which you should do first in the Simplification of the expression -3(-5) - 16 is -3 times -5. option A

Simplification

Based on the principle of BODMAS

B = Bracket

O = of

D = Division

M = Multiplication

A = Addition

S = Subtraction

-3(-5) - 16

open parenthesis

= 15 - 16

= -1

Therefore, the operation which you should do first in the Simplification of the expression -3(-5) - 16 is -3 times -5. option A

I need help figuring out what I did wrong

rewona [7]

Answer:

Step-by-step explanation:

Using the addition formula for sine

sin(a + b) = sinacosb + cosasinb

and the exact values

sin( $\frac{\pi }{4}$ ) = cos( $\frac{\pi }{4}$ ) = $\frac{\sqrt{2} }{2}$ , cos( $\frac{\pi }{6}$ ) = $\frac{\sqrt{3} }{2}$ , sin( $\frac{\pi }{6}$ ) = $\frac{1}{2}$

Note that $\frac{5\pi }{12}$ = $\frac{\pi }{4}$ + $\frac{\pi }{6}$ , thus

sin( $\frac{5\pi }{12}$ )

= sin( $\frac{\pi }{4}$ + $\frac{\pi }{6}$ )

= sin( $\frac{\pi }{4}$ )cos( $\frac{\pi }{6}$ ) + cos( $\frac{\pi }{4}$ )sin( $\frac{\pi }{6}$ )

= ( $\frac{\sqrt{2} }{2}$ × $\frac{\sqrt{3} }{2}$ ) + ( $\frac{\sqrt{2} }{2}$ × $\frac{1}{2}$ )

= $\frac{\sqrt{6} }{4}$ + $\frac{\sqrt{2} }{4}$

= $\frac{\sqrt{6}+\sqrt{2} }{4}$ → D

To make fruit punch for a party, Alison used 3 quarts of pineapple juice and 2 gallons if orange juice. There are 4 quarts in a

REY [17]

Since we know there are 3 quarts of pineapple juice and 2 gallons of orange juice the first thing you need to do is convert the units of the orange juice to quarts.
If there are 4 quarts in a gallon and we have 2 gallons then we have 8 quarts (4*2)
So 3 quarts of pineapple juice to 8 quarts of orange juice.
The ratio would be 3:8

Given m\parallel nm∥n, find the value of x and y.

Sindrei [870]

Answer:

See below ↓↓

Step-by-step explanation:

Finding x

Both the angles containing the x variable are on the same side of the transversal
There is a property which states that : two angles on the same side of the transversal are supplementary
Therefore, they add up to 180°
⇒ 8x + 12 + 2x + 18 = 180
⇒ 10x + 30 = 180
⇒ 10x = 150
⇒ x = 15

Finding y

The angles at the top are vertically opposite angles (VOA), meaning that they are equal
⇒ 8x + 12 = 3y - 18
⇒ 3y = 8(15) + 12 + 18
⇒ 3y = 120 + 30
⇒ 3y = 150
⇒ y = 50
