One number is 20 more than two times another. Find the two numbers if their sum is 110.

Answers

Answer:

30, 80

Step-by-step explanation:

Let the smaller number be [tex]x[/tex]. Then, the other number is [tex]2x+20[/tex]. The sum is 110, so

[tex]x+(2x+20)=110.[/tex]

Simplifying gives

[tex]3x+20=110[/tex].

Subtracting 20 from both sides gives

[tex]3x=90[/tex].

Dividing by 3 gives

[tex]x=30[/tex].

The smaller number is 30 and the larger number is 2(30)+20=80.

What is equivalent expression?

Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.

Given information-

The expression given in the problem is,

[tex]\left((4^{\dfrac{5}{4}}\times4^{\dfrac{1}{4}}\div 4^{\dfrac{1}{2}} \right)^{\frac{1}{2}}[/tex]

Let the result of the given expression is x. Rewrite the given expression as,

[tex]x=\left(\dfrac{4^{\dfrac{5}{4}}\times4^{\dfrac{1}{4}}}{4^{\dfrac{1}{2}}} \right)^{\frac{1}{2}}[/tex]

When the two number is multiplies with the same base, the powers of the number is added in result. Thus,

[tex]x=\left(\dfrac{4^{(\dfrac{5}{4}+\dfrac{1}{4})}}{4^{\dfrac{1}{2}}} \right)^{\frac{1}{2}}\\x=\left(\dfrac{4^{(\dfrac{3}{2})}}{4^{\dfrac{1}{2}}} \right)^{\frac{1}{2}}[/tex]

When the two number is divided with the same base, the powers of the number is subtracted in result. Thus,

[tex]x=\left(4^{\dfrac{3}{2}-\dfrac{1}{2}} \right)^{\frac{1}{2}}[/tex]

[tex]x=\left(4^1} \right)^{\frac{1}{2}}\\x=\left(4} \right)^{\frac{1}{2}}\\x=(2^2)^{\dfrac{1}{2}} \\x=2[/tex]

Answer:

The side length for A and B is 30 and the side length for B and D is 16, in the new dilated rectangle. The reason we multiplied by 2 is because 2 is greater than 1, and this means the image is an enlargement.

Step-by-step explanation:

Dilation is where the polygon grows or shrinks but keeps the same overall shape. A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image. If the scale factor is between 0 and 1 the image is a reduction. If the scale factor is greater than 1, the image is an enlargement. This means that the image, A’, is twice as large as the pre-image A. This means that the image, A’, is twice as large as the pre-image A.

Since 2 is greater than 1, the image is an enlargement

So we do 2*15 and 2 * 8

And we get

30 and 16

The side length for A and B is 30 and the side length for B and D is 16.

Answers

Answer:  Around 4681 grills

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

Explanation:

x = number of years

y = number of grills sold

The equation we'll use is the exponential equation [tex]y = 3300(1.06)^x[/tex]

The 3300 of course is the initial amount sold. The 1.06 as the base indicates that the sales increase by 6% each year. Think of it the 1.06 as 1+0.06 = 100% + 6%

If we plugged x = 0 into that equation, then we get

[tex]y = 3300(1.06)^x = 3300(1.06)^0 = 3300[/tex]

which helps confirm the correct equation.

----------------

Now plug in x = 6 to find the sales for year 6.

[tex]y = 3300(1.06)^x = 3300(1.06)^6 \approx 4681.11 \approx 4681[/tex]

The projected sales for year 6 are about 4681 grills. This is an estimate based on the assumption that the sales will increase by 6% each year. Of course, the reality is that things aren't always so simple like this (but it should give a fairly good idea of what's going on).

19800. Because 3300 x 6 = 19800.

The image of the point (2, -1) under a translation is (4,2). Find the coordinates of the image of the point (-2,9) under the same translation.

Answers

Answer:

The coordinates of the image of the point (6,6) under the same  translation is: (9, 2)

Hence, option C is correct.

Step-by-step explanation:

The image of the point (2, 1) under a translation is (5, -3).

It means when we horizontally move 3 units to the RIGHT i.e. adding 3 units to the x-coordinate and vertically move 4 units DOWN i.e. subtracting 4 units from the y-coordinate of the original point (2, 1), we get the coordinates of the image (5, -3).

Thus,

The rule of translation can be formulated such as:

(x, y) → (x + 3, y - 4)

(2, 1) → (2 + 3, 1 - 4) → (5, -3)

Thus,

Under the same rule of translation, we can determine the coordinates of the image of the point (6,6):

(x, y) → (x + 3, y - 4)

(6, 6) → (6 + 3, 6 - 4) → (9, 2)

Therefore, the coordinates of the image of the point (6,6) under the same  translation is: (9, 2)

Hence, option C is correct.

Step-by-step explanation:

given adjacent: 56, given angle: 48°, asked to find hypotenuse, x?

Using cosine rule:

→ adjacent/hypotenuse = cos(∅)

→ 56/hypotenuse = cos(48)

→ hypotenuse = 56/cos(48)

→ hypotenuse = 83.7 units

Answer:

83.7

Step-by-step explanation:

We can solve this using SOHCAHTOA:

RQ is adjacent to angle Q and x is the hypotenuse, so we must use the cosine function.

[tex]cosQ = \frac{RQ}{SQ}\\ cos(48) = \frac{56}{x}\\ x = \frac{56}{cos(48)}\\ x = 83.7[/tex]

The probability of winning a certain game is 0.5. If at least 70 percent of the games in a series of games are won, the player wins a prize. If the possible choices for n are n

Answers

The equation that allows determining the probability that the player wins the prize after n games is [tex]0.35^n[/tex] = Probability. The player should choose n = 10.

The simple definition of probability is the likelihood that an individual event will occur. It can be discussed the probabilities of distant outcomes, or how probable they are, whenever we're skeptical of how an occurrence will turn out. Statistics refers to the study of events subject to probability.

First, solve the following equation to find the likelihood of the player winning the prize after n games given that the probability of winning a specific game is 0.5 and that the player wins a prize if at least 70[tex]\%[/tex] of the games in a series are won.

[tex]Probability = 0.5^n \times 0.70[/tex]

[tex]Probability = 0.35^n[/tex]

It is evident here that the larger the value of n, the lesser the chances to win.

For example, if there were five games played, the equation would be as follows:

[tex]0.35^5 = 0.005[/tex]

So. the value of n chosen by the player should be 10.
