The sum of twice Emily's age and her mom's age is 78. Her mom's age is 4 times Emily's age. What is Emily's age?

Answer:

= 4374.

Step-by-step explanation:

 it is important to understand the pattern hidden in such problem.Let’s give it a try 2, 6, 18, 54 and so on.It can be written as 2, 3*2, 9*2, 27*2 and so on.

This can be further written as2 (1, 3, 9, 27, and so on) as 2 is common in every term.Now if you see the chain 1,3,9, 27 and so….you will see a pattern hidden i.e. 3=1*3 ,9=1*3*3, 27=1*3*3*3 now 27 is the 4th term consist of three 3. So 8th term would consist of seven 3. 8th would be 8th term = 1*3*3*3*3*3*3*3 = 2187 Hence the 8th term for the series 2,6,18,54 would be= 2*2187 = 4374.

Answer:

64 oz jar of peanut butter $6.99

Step-by-step explanation:

16 oz jar of peanut butter for $2.49 is more expensive because if you multiply $2.49 by 4 to buy 64 it equals $9.96 which is more expensive

Answer:Yes, they are similar.

If two triangles are congruent then all corresponding sides as well as corresponding angles of one triangle are equal to those of other triangles. This can happen in four cases

Step-by-step explanation:

Answer:

yes the are similar

Step-by-step explanation:

they are similar since they both have a 90⁰ angles and the lines are =. but I don't know if they count the size of the triangle if yes then they are not similar since they do not have the same area

Answer:

3/4 x 3/8 = 9/32

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.

Answer: [tex]\frac{\pi *r^{2} }{4}[/tex]

Step-by-step explanation:  We know that the formula for the area of a whole circle is πr². A quarter circle is one-fourth of a circle, so if we divide the area of the whole circle into four, we can find the area of the quarter circle: [tex]\frac{\pi *r^{2} }{4}[/tex]

Given:

The equation is

[tex]y=\log_2x[/tex]

The domain is [tex]\{\dfrac{1}2, 1, 2, 4, 8, 16\}[/tex].

To find:

The graph of six points that would satisfy the equation.

Solution:

We have,

[tex]y=\log_2x[/tex]

For [tex]x=\dfrac{1}{2}[/tex],

[tex]y=\log_2\dfrac{1}{2}[/tex]

[tex]y=\log_22^{-1}[/tex]

[tex]y=-1[/tex]                          [tex][\because \log_aa^x=x][/tex]

Similarly, at x=1,

[tex]y=\log_22^0[/tex]

[tex]y=0[/tex]

At x=2,

[tex]y=\log_22^1[/tex]

[tex]y=1[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=4,

[tex]y=\log_22^2[/tex]

[tex]y=2[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=8,

[tex]y=\log_22^3[/tex]

[tex]y=3[/tex]                      [tex][\because \log_aa^x=x][/tex]

At x=16,

[tex]y=\log_22^4[/tex]

[tex]y=4[/tex]                      [tex][\because \log_aa^x=x][/tex]

Plot the points [tex](\dfrac{1}{2},-1),(1,0),(2,1),(4,2),(8,3),(16,4)[/tex] on a coordinate plane as shown below.

Answer:

The are is 64 cm.

Step-by-step explanation:

[tex]\huge\text{hi}[/tex]

5 * 2 = 10

12 * 4.5 = 54

54 + 10 = 64cm

Answer:

The answer is $240

Step-by-step explanation:

You multiply 1.5 times 60 minutes and get 90, you then add 150 and 90 and you get 240.

Answer:

[tex]y = -\frac{2}{3}x + 5[/tex]

Step-by-step explanation:

First you have to find the slope

[tex]m = \frac{7 - 3}{-3 - 3} = \frac{4}{-6} = -\frac{2}{3}[/tex]

Now use the point-slope form by using one of the points and the slope.  Let's use the point (3, 3)

[tex]y - 3 = -\frac{2}{3} (x - 3)[/tex]

Multiply thru the equation by 3 to remove the fraction

3y - 9 = -2(x - 3) =

3y - 9 = -2x +6

3y = -2x + 15

[tex]y = -\frac{2}{3}x + 5[/tex] is the equation in slope-intercept form

Answer:  0.25x + 3 ≤ 10;  28 games

Note how we have a "less than or equal to" sign, instead of simply a "less than" sign.

======================================================

Work Shown:

x = number of games

0.25x = amount spent on games only

0.25x+3 = total amount spent (games+admission)

total spent ≤ $10   since $10 is the most we have

0.25x + 3 ≤ 10 is the inequality we need to solve

0.25x ≤ 10-3  .... subtract 3 from both sides

0.25x ≤ 7

x ≤ 7/0.25   ............ divide both sides by 0.25

x ≤ 28

Since x is less than or equal to 28, this means the largest x can get is 28.

We can think of this as the ceiling value so to speak.

So the maximum number of games that can be played is 28.

Answer:

3

Step-by-step explanation:

Mathematically, the highest degree of a cubic expression is 3

The number of degrees a polynomial has will dictate the number of roots the polynomial will have

Since the degree of the polynomial is 3, then we have that the number of factors it will have is 3

Answer:

x= 25

3x-4=71

2x+3=53

2x+6=56

Step-by-step explanation:

Answer:

x = 10

Step-by-step explanation:

[tex] \frac{10x + 8}{2x + 7} = 4[/tex]

or, 10x + 8 = 4(2x + 7)

or, 10x + 8 = 8x + 28

or, 10x - 8x = 28 -8

or, 2x = 20

or, x = 20/2

or, x = 10

x = 10

Answer:

2.64 km

Step-by-step explanation:

24 laps each of 110 meters means a total of :

24 * 110 = 2640 m

which translated to km are: 2.64 km

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes
