Answer:

x=21

Step-by-step explanation:

Hello There!

In order to find the value of x we need to find the value of y

The angle labeled y and the right angle are vertical angles with the angle labeled 5y +10 therefore they are congruent

so y+90=5y+10

step 1 subtract y from each side

5y-y=4y

now we have

90=4y+10

step 2 subtract each side by 10

90-10=80

now we have

80=4y

step 3 divide each side by 4

80/4=20

so y =20

now we plug in y to (5y+10)

5x20=100

100+10=110

So now we can find x

The angle labeled 3x+7 is supplementary with the angle that is equal to 110

meaning that the sum of the two angles equal 180

so 180 = 3x+110+7

step 1 combine like terms

110+117

now we have

180=3x+117

step 2 subtract each side by 117

180-117=63

now we have 3x=63

step 3 divide each side by 3

63/3=21

so we can conclude that x = 21

Answer:

x = 21°

Step-by-step explanation:

y = 180° - 90° - (3x+7)°

y = 83° - 3x

(5y + 10) and (3x + 7) are supplementary angles (their sum is 180°) so:

(5y + 10) + (3x + 7) = 180°

reduce:

5y + 3x = 163°

substitute for y:

5(83° - 3x) + 3x = 163°

415° - 15x + 3x = 163°

reduce:

-12x = -252

divide both sides by -12:

x = 21°

y = 83° - 3(21°) = 20°

check:

(5(20) + 10) + (3(21) + 7) = 180°

110° + 70° = 180°

Answer:

C

Step-by-step explanation:

Hello There!

The height of the water starts at 3 feet and its receding at a rate of .75 feet an hour

receding means to move farther away from previous position

so the equation would be

3-.75t

or

-.75t + 3

So we can conclude that the answer is C

Answer: False. When multiplying or dividing by an negative inequality you flip the sign.

Answer:

2. y - (-5) = -3 (x - 5)

3. y = -5/2

Step-by-step explanation:

Point intercept form: y - y₁ = m (x - x₁)

Where y and x are just kept as y and x, y₁ and x₁ are the parts of a coordinate, and m = slope.

2. The points are (5, -5) and the slope is -3. Plug this into y - y₁ = m (x - x₁) to get

y - (-5) = -3 (x - 5)

3. As stated, parallel lines have the same slope, so the slope of the line would be -5/2. The origin is (0, 0), so plug these two numbers in.

y - y₁ = m (x - x₁)

y - 0 = -5/2 (x - 0)

y = -5/2

Because Bradley's carton is taller than Josh's, Bradley would drink more milk.

Let us assume that Bradley carton has 100 quarts . If he drank 1/4, he would drink 25 quarts of milk. If Josh carton is 80 quarts full of milk, he would drink 20 quarts of milk. this example shows that they would not drink the same amount of milk

Step-by-step explanation:

A taller carton would contain more ounces of milk.

Answer: 11, 6.5 ft

Step-by-step explanation:

Given

The length of the roll is [tex]100\ ft[/tex]

The length required for a pump is [tex]8\ \frac{1}{2}\ ft=\frac{17}{2}\ ft[/tex]

No of pumps(n) we get

[tex]\Rightarrow \dfrac{100}{\frac{17}{2}}=11.76\ \approx 11[/tex]

length for 11 pumps

[tex]\Rightarrow 11\times \frac{17}{2}=93.5\ ft[/tex]

The remaining length of the tube is

[tex]\Rightarrow 100-93.5=6.5\ ft[/tex]

Question:

For which value of x must the expression √97x be further simplified?

A. 5    B. 10     C. 15     D. 20

Answer:

[tex]D.[/tex]  [tex]x = 20[/tex]

Step-by-step explanation:

Given

[tex]\sqrt{97x[/tex]

Required

For what value of x can it be simplified

From the list of options, only (D) is correct

D. 20

Substitute 20 for x in [tex]\sqrt{97x[/tex]

[tex]\sqrt{97 x} = \sqrt{97 * 20}[/tex]

Express 20 as 4 * 5

[tex]\sqrt{97 x} = \sqrt{97 * 4 * 5}[/tex]

Reorder

[tex]\sqrt{97 x} = \sqrt{4 *97 * 5}[/tex]

Split

[tex]\sqrt{97 x} = \sqrt{4} *\sqrt{97 * 5}[/tex]

[tex]\sqrt{97 x} = 2*\sqrt{97 * 5}[/tex]

[tex]\sqrt{97 x} = 2*\sqrt{485}[/tex]

[tex]\sqrt{97 x} = 2\sqrt{485}[/tex]

With other values of x, the given expression can not be simplified.

Hence:

[tex]x = 20[/tex]

7a.C

7b.Angle AED

7c.Angle 8

7d. Angle 6 and 8

Step-by-step explanation:

6a. The labeled angles are vertical angles so we set them equal to each other.

[tex]7x - 8 = 6x + 11[/tex]

[tex]7x = 6x + 19[/tex]

[tex]x = 19[/tex]

7a.Angle 11 is near Point C so Point C is the vertex.

7b. Angle 5 vertex is E so we can use any 3 points as an angle as long as E is in the middle example, and the angles are on the left side so we can use

[tex]aed[/tex]

Write the angle sign as well.

7c. Angle 6 is vertical from Angle 8.

7d. Angle 7 and 6 form a linear pair and since Angle 6=Angle 8, Angle 7 and 8 form a linear pair as well.

Step-by-step explanation:

Answer: Si fuera de los que solo fuman sería del 43,5% si solo de los que lo beben sería del 20,5% si fueran los dos sería del 59%.

Step-by-step explanation:

The percentage of the population smokes or drinks is 52%.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

We are given that;

The drink is half, third and quarter of the percentage

The sum of these percentages must be 100%, so we can write an equation:

x + (1/2)x + (1/3)x + (1/4)x = 100

To solve for x, we need to simplify and isolate x. We can do this by multiplying both sides by 12, the least common multiple of 2, 3, and 4:

12x + 6x + 4x + 3x = 1200

25x = 1200

x = 1200/25

x = 48

This means that 48% of the population neither smokes nor drinks. Therefore, the percentage of the population that smokes or drinks is:

(1/2)x + (1/3)x + (1/4)x

= (1/2)(48) + (1/3)(48) + (1/4)(48)

= 24 + 16 + 12

= 52

Therefore, the percentage answer will be 52%.

The complete question is;

In a city, the percentage of the population that smokes and drinks, the one who only smokes and the one who only drinks, it is half, third and quarter of the percentage that neither smokes nor drinks. Determine what percentage of the population smokes or drinks.

An area that is 20 feet wide and 25 feet long will be 20*25 = 500 square feet large. Division tells us how many times one number is contained within a number, so to find how many 2.5 square feet large people fit in a 500 square feet large space, we do 500/2.5 = 200 people.
