$\textsf{Hey there!}$

$\mathsf{Equation: 6 * 7- 3^2 *9+4^3}$

$\mathsf{3^2 = 3*3=9}$

$\mathsf{4^3= 4*4*4=16*4 = 64}$

$\mathsf{6*7 = 42}$

$\mathsf{9*9= 81}$

$\mathsf{New\ equation: 42 - 81 + 64}$

$\mathsf{42 -81= -39}$

$\textsf{New equation: -39 + 64}$

Answer:

-10

Step-by-step explanation:

First, evaluate the terms with exponents.

7-3²·9+4³

With that, you get:

7-9·9+64

Multiply -9×9

7-81+64

Then, add or substract from left to right.

Your final answer is -10.

arun went for a movie nine days ago. he goes to watch movies only on thursdays. what day of the week is today? wednesday saturday friday sunday

Answers

Answer: What happened on saturday, add up the days on a notebook (make a chart) so you can figure out the rightful answer!!

Step-by-step explanation:

Today is Saturday.
Based on the information given, Arun goes to watch movies only on Thursdays. If he went for a movie nine days ago, we can count backwards from today to determine the day of the week it was.
Let's start counting backwards:
- Today is Saturday (Day 1)
- Yesterday was Friday (Day 2)
- Two days ago was Thursday (Day 3)
- Three days ago was Wednesday (Day 4)
- Four days ago was Tuesday (Day 5)
- Five days ago was Monday (Day 6)
- Six days ago was Sunday (Day 7)
- Seven days ago was Saturday (Day 8)
- Eight days ago was Friday (Day 9)
Therefore, if Arun went to watch a movie nine days ago, it was on a Friday.

A straight river flows east at a speed of 11 mi/h. A boater starts at the south shore of the river and wants to arrive at a point on the north shore of the river directly opposite the starting point. The motorboat has a speed of 22 mi/h relative to the water. In what direction should the boat be headed?

Answers

The direction should the boat be headed is 60 degrees north 30 degrees west and this can be determined by using the trigonometric functions.

Given :

A straight river flows east at a speed of 11 mi/h.
A boater starts at the south shore of the river and wants to arrive at a point on the north shore of the river directly opposite the starting point.
The motorboat has a speed of 22 mi/h relative to the water.

The following steps can be used in order to determine the direction should the boat be headed:

Step 1 - The trigonometric function can be used in order to determine the direction should the boat be headed.

Step 2 - The mathematicalexpression of the cosine function is given by:

$\rm cos\theta=(base)/(hypotenuse)$

where $\theta$ is the direction should the boat be headed.

Step 3 - Now, substitute the known values in the above formula.

$\rm cos\theta=(11)/(22)$

Step 4 - Simplify the above expression.

$\rm cos\theta=(1)/(2)$

$\theta = 60^\circ$

Step 5 - So, the angle from the west axis is given by:

$90-60=30^\circ$

The direction should the boat be headed is 60 degrees north 30 degrees west.

Answer:

N 30 degree W

Step-by-step explanation:

We are given that

Speed of river flows=11 mi/h(East)

Speed of motorboat relative to water=22mi/h

We have to find the direction in which the boat should be headed.

Let direction of the boat = $\theta$

We know that

$Cos\theta=(Base)/(hypotenuse)$

Using the formula

$Cos\theta=(11)/(22)=(1)/(2)$

$Cos\theta=Cos60^(\circ)$

Because $Cos60^(\circ)=(1)/(2)$

$\theta=60^(\circ)$

Angle from the west axis= $90-60=30^(\circ)$ W

Hence, the direction of boat should be headed in N 30 degree W

Solve for x.

3x - 5x + 8x + x = 42

A. 6
B. 7
C. 8

Answers

The answer would be "6" because you have to calculate the difference then calculate the sum, calculate the sum again, then divide both sides by 7 and that gives you 6.

Combine all alike x terms and you get 7x=42

Divide 7 on each side of equation

You get A.x=6
