Answer:

7.35

Step-by-step explanation:

Andrea uses 9.8 pints of white and blue paints to paint her bedroom walls

1/4 of this amount is white paint

= 1/4 × 9.8

= 0.25×9.8

= 2.45

Therefore the amount of blue paint can be calculated as follows

9.8-2.45

= 7.35

Hence 7.35 are blue paint

 Respuesta:98%

Explicación pasto a paso: Sumaremos la cantidad indicada con el 100%. Por ejemplo: 10%+100%= 110%

Entonces:

110/100 × 120/100 × 150%= 198%

Luego restamos: 198% - 100%= 98% Respuesta: Aumento único= 98%

The answer is C.

Answer: $3.75

Step-by-step explanation:

The amount that you would save is 5% of your monthly bill of $75.

The total amount that you would pay is:

= 75 - 3.75

= $71.25

Answer:

-2 is rational

This is because every negative integer is a negative rational number.

We know that -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on …….

In other words, any negative integer n can be written as n = n/1, here n is negative and 1 is positive.

So, negative 2 is rational.

Answer: 2 5/12

Step-by-step explanation:

Trey bought 3¾ pounds of apples from the grocery store. Corinne bought 1⅓ pounds of grapes from the grocery store.

To know how many more pounds of fruit that Trey bought, we have to find the difference between the value given above and this will be:

= 3¾ - 1⅓

= 3 9/12 - 1 4/12

= 2 5/12

Trey bought 2 5/12 pounds more.

Answer:

Part A: [tex]12x+16\leq 580[/tex]

Part B: $47 per month

Step-by-step explanation:

Part A: 12 months in a year. Pays x amount of $ per year, with an additional $16 initiation fee. He wants to spend less than $580 total a year. Thus, [tex]12x+16\leq 580[/tex].

Part B: Solve the inequality for x.

$580 - $16 = $564

x = $564/12 = $47

Answer:

D. 8.8

Step-by-step explanation:

As the pythagorean theorem.

A² + B² = C²,

5.4 × 5.4 + 7 × 7 = C²,

29.16 + 49 = C²,

78.16 = C²,

8.8 ≈ C

Answer:

C. e = 8.1

Step-by-step explanation:

Answer:

arc BD = 100

Step-by-step explanation:

arc BD = arc CA because ∠AOC = ∠BOD (vertical angles)

arc BD = 100

Answer:

we have

sin30=perpendicular/hypotenuse

1/2=x/10

x=½×10=5

x=5

is your answer

Answer:

x = 50°

Step-by-step explanation:

The triangle has 3 congruent sides and is therefore equilateral.

The 3 angles are then congruent, each 60°

The left angle in the quadrilateral is adjacent to 60° of the triangle

180° - 60° = 120° ← angle inside quadrilateral

The sum of the interior angles of a quadrilateral = 360°

Subtract the sum of the angles from 360° for x

x = 360° - (120 + 90 + 100)° = 360° - 310° = 50°

Answer:

the fourth

Step-by-step explanation:

Answer:

x = 17.5

y = 5

Step-by-step explanation:

Similar means that corresponding angles (same colors in this case) are the same. Rotate the 2nd figure on the right in your mind until the angle label colors fit the 1st figure, just so you can tell what's what. Then you can create ratios with corresponding sides that include only one of the unknowns. So 1st we use

x/7 = 15/6

x = 15/6 * 7

x = 17.5

and

y/12.5 = 6/15

y = 6/15 * 12.5

y = 5

0

Answer:

They will blow together again at 6:00 am

Step-by-step explanation:

Guard 1 whistles every 50 minutes.

Guard 2 whistles every 60 minutes.

Guard 1 whistles every 100 minutes.

Assuming that at the beginning they whistle together, the next time that they will whistle together is after the smallest common multiple of 50, 60, and 100.

Because one of the numbers is 100, it only has multiples like:

100*2 = 200

100*3 = 300

100*4 = 400

etc...

So we need to find a common multiple of 50 and 60 that is also a multiple of 100.

For example, the multiples of 50 that are also multiples of 100 are:

50*2 = 100

50*4 = 200

50*6 = 300

And the multiples of 60 that are also multiples of 100 are:

60*5 = 300

(this is the only one)

Then we can see that a common multiple of 50, 60 and 100 is 300.

Then they will whistle together 300 minutes after the first common whistle.

We know that they blow together at 1:00 am

300 minutes after it is:

First, we need to write 300 minutes in hours.

We know that one hour has 60 minutes.

then 300 minutes = (300 minutes/60 minutes) hours = 5 hours.

300 minutes after 1:00 am is the same as 5 hours after 1:00 am

And 5 hours after 1:00 am is 6:00 am

They will blow together again at 6:00 am

Answer:

35

Step-by-step explanation:

9Kg =63N

5Kg=X (Cross Multiple)

=X×9 =5×63

divide both sides by 9

X=5×63

---------

9

=35

Answer:

35 N

Step-by-step explanation:

let w = weight of object

and m = mass of object

w = mk   where k is the constant of proportion

63 = 9k

k = 7

So, w = 7m

w = 7(5) = 35 N
