Later, Divide it by 2 and hence, your answer is 25.....;)

Answer:

16 years

Step-by-step explanation:

Given data

For the first tree

let the expression for the height be

y=4+x--------------1

where y= the total height

          4= the initial height

          x= the number of years

For the second tree, the expression is

y=12+0.5x-------------2

Equate 1 and 2

4+x=12+0.5x

x-0.5x=12-4

0.5x= 8

x= 8/0.5

x=16

Hence it will take 16 years for both trees to have the same height

Answer: $20,000

Step-by-step explanation:

Given

Interest decreases from 3.75% to 3.5% in a year

This change in the rate of interest brings a yield of 50$

Earlier interest was

[tex]S.I_e=\dfrac{P\times 3.75\times 1}{100}[/tex]

Now, interest is

[tex]S.I._n=\dfrac{P\times 3.5\times 1}{100}[/tex]

change gives 50$ i.e.

[tex]\Rightarrow \dfrac{P\times 3.75\times 1}{100}-\dfrac{P\times 3.5\times 1}{100}=50\\\\\Rightarrow \dfrac{P\times (3.75-3.5)\times 1}{100}=50\\\\\Rightarrow P=\dfrac{50\times 100}{0.25}=\$20,000[/tex]

Answer:

y=18 x=15

Step-by-step explanation:

1.

multiplyboth sides by 3

2(x-6)=18

divide both sides by 2

x-6= 9

add 6 on both sides

x=15

2.

add 6 on both sides

2/3y= 12

multiply both sides by 3

2y=36

divide both sides by 2

y=18

Answer:

The width would be 12.5 feet.

Step-by-step explanation:

On a square all the sides are the same to the height, length, and width are all 12.5 feet.

Answer:

B: 80

Step-by-step explanation:

Answer: The probability that at least one of the envelopes is red is 1/9 (simplified) or 9/81.

Step-by-step explanation:

There are a total of 9 envelopes. If two are selected at random with replacement the probability for both envelopes is 3 / 9 or 1/3. Since there are two you would do 1/3 * 1/3 to get 1/9 or 3/9 * 3/9 to get 9/81.

Answer:

The slope is 3

Step-by-step explanation:

m = rise/run

m = (y2 - y1)/(x2-x1)

points: (0,-5), (1,-2)

m = ((-5) - (-2))/ ((0) - (1))

m = (-5 + 2)/ (-1)

m = -3/-1

m = 3

Answer:

Average time for West Middle was maximum.

Step-by-step explanation:

Average time for a track meet for schools = [tex]\frac{\text{Time}}{\text{Distance}}[/tex]

For Eastbay Middle,

Average time per mile = [tex]\frac{42}{7}[/tex]

                                     = 6 minutes per mile

For Northwest Middle,

Average time = [tex]\frac{25}{5}[/tex]

                       = 5 minutes per mile

For South Central Middle,

Average time = [tex]\frac{28}{4}[/tex]

                       = 7 minutes per mile

For West Middle,

Average time = [tex]\frac{48}{6}[/tex]

                       = 8 minutes per mile

Therefore, average time for West Middle (8 minutes per minute) was maximum.

Answer:

of triangle =12base×height

Area of triangle =2x2−11x+15

base =2x−5

Plugging in the given;

2x2−11x+15=12(2x−5)×height

2x2−11x+15=2x−52×height

2x2−11x+151=2x−52×height

2(2x2−11x+15)=(2x−5)×height

4x2−22x+30=(2x−5)×height

4x2−22x+302x−5=height

Resolving the quadratic equation;

(4x2−22x+30)

Simplifying;

4x

Answer:

2x-6

Step-by-step explanation:

height : 2(2x^2-11x+15)/(2x-5)

(4x^2-22x+30)/(2x-5)

Δ/4 = 121 - 120 = 1

x1 = (11+1)/4 = 3

x2 = (11-1)/ 4 = 5/2

4(x-5/2)(x-3)

(4x-10)(x-3)/(2x-5)

2(2x-5)(x-3)/(2x-5)

2x-6

Proof

(2x-6)(2x-5)/2

2(x-3)(2x-5)/2

2x^2-5x-6x+15

2x^2-11x + 15

Answer:

Answer:

Question is: Mom can make 10 brownies from a 12-ounce package. The brownie mix is also sold in 1 and a half-pound bags. How many bags would be needed to make  120 brownies?

Step-by-step explanation:

As mentioned in question,

10 brownies made from = 12 ounce package

120 brownies will be made from = 10 * 12 packages

now 12 packages will have ounces = 12 * 12 = 144 ounces

We also know that packages are one and a half pounds

Applying conversion factor = 1.5 pound = 24 ounces

Now we can find answer: 144 ounces total requires / 24 ounces

Answer = 6 bags

6 bags of 1.5 pounds will be required for 120 brownies.

Answer:

y=8-6x

Step-by-step explanation:

Answer:

y=0

x=4/3

Step-by-step explanation:

6x+y=8

x =8-y/6

substitute 8-y/6 in second equation

42*8-y/6 +7y=56

7(8-y) +7y=56

56-y+ 7y=56

-y+ 7y=0

6y=0

y=0

6x+y=8

6x+0=8

x=8/6

x=4/3

The value of x in the triangle is 35 degrees, option A is correct.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Let us find the interior angles

The sum of interior and exterior angle is 180

95+x=180

x=85

We know that the sum of three angles is 180 degrees by angle sum property

60+85+x=180

145+x=180

Subtract 145 from both sides

x=180-145

x=35 degree

Hence, the value of x in the triangle is 35 degrees, option A is correct.
