Angle-5 and angle-7 are 'vertical angles', so they're equal,
and we can write ...
 10x- 9 = 9x

Subtract 9x from each side: x - 9 = 0

Add 9 to each side: x = 9

Now that we know what 'x' is, we can find the size of Angles-5 and -7 .

Angle-7 = 9x = 81° .

Now look at Angle-6 ... the one that's the answer to the problem.

Angle-6 and -7 together make a straight line, so they must
add up to 180°.

 Angle-6 + 81° = 180°

Subtract 81° from each side: Angle-6 = 99° .

Malcolm is trying a very low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels s

Ostrovityanka [42]

Answer:

The correct option is 2.

Step-by-step explanation:

The given inequalities are

$50$ .... (1)

$2x+10$ .... (2)

Solve each inequality.

Subtract 10 from each side of inequality (1).

$50-10$

$40$

Divide both the sides by 2.

$20$

The value of x is more than 20.

Subtract 10 from each side of inequality (2).

$2x+10-10$

$2x$

Divide both the sides by 2.

$x$

The value of x is less than 50.

Since x > 20 and x < 50, therefore Malcolm needs to consume more than 20 grams of carbohydrates, but less than 50 grams of carbohydrates.

Hence the correct option is 2.

A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind. Find the speed of the wind

Lunna [17]

Given:

A pilot can travel 450 miles with the wind in the same amount of time as 360 miles against the wind.

Pilot's speed in still air is 315 miles per hour.

To find:

The speed of the wind.

Solution:

Let the speed of wind be x miles per hour.

Speed with wind = 315+x miles per hour

Speed against wind = 315-x miles per hour

We know that,

$Time=\dfrac{Distance}{Speed}$

According to the question,

$\dfrac{450}{315+x}=\dfrac{360}{315-x}$

Divide both sides by 90.

$\dfrac{5}{315+x}=\dfrac{4}{315-x}$

By cross multiplication, we get

$5(315-x)=4(315+x)$

$5(315)-5x=4(315)+4x$

$5(315)-4(315)=4x+5x$

$(5-4)315=9x$

Divide both sides by 9.

$\dfrac{(1)315}{9}=x$

$35=x$

Therefore, the speed of wind is 35 miles per hour.

What is the greatest 0.45 0.097 0.375 0.209

Nady [450]

Answer:

Largest number is : 0.45

Step-by-step explanation:

0.45, 0.097, 0.375, 0.209

Here all numbers have first digit is 0.

So, look at the first decimal place from all decimal numbers.

4 from .45, 0 from .097, 3 from .375 and 2 from .209

Largest digit is 4

So, largest digit is 0.45

So, final answer is 0.45

I hope it will help you.

Please help me solve this

OlgaM077 [116]

Answer:

645320

Step-by-step explanation:

Given: 6_5_2_

If a multiplication sign is placed between the second and third digit, and an equal sign is placed between the third and fourth digit, then

6_ × 5 = _2_

The passcode contains 6 DIFFERENT digits, so we know the missing numbers cannot be 6, 5, or 2.

So, do a trial and error session of multiplying 5 by numbers it could possibly be (60, 61, 63, 64, 67, 68, 69).

64 × 5 = 320. It is the only equation that is both correct and matches the digits given, so the missing digits are 4, 3, and 0. Barry's passcode is 645320.
