for the two given fractions 3/4 and 1/6 we have:

Here we have two fractions, 3/4 and 1/6, and we want to find the sum, product, and quotient between them.

First let's do the sum:

3/4 + 1/6

We just need to find a common denominator, which can be 12, so we can rewrite it as:

9/12 + 2/12 = 11/12

The sum of the two fractions is 11/12

Now the product, it is, we multiply denominator with denominator and numerator with numerator, we will get:

(3/4)*(1/6) = (3*1)/(4*6) = 3/24 = 1/8

The product between the two fractions is equal to 1/8.

Finally, the quotient, this is:

The product between the first numerator and second denominator, and between the first denominator and second numerator, so the quotient becomes:

(3/4)/(1/6) = (3/4)*(6/1) = (3*6)/(4*1) = 18/4 = 9/2

Then we conclude that for the two given fractions 3/4 and 1/6 we have:

Hey there!

(78 - x) + (84 - 3x)

= 78 - x + 84 - 3x

If Benjamin has 25 papayas, given the ratio of papayas to pears as 50:94, he has 47 pears.

The ratio is the numerical relationship that one variable has when compared with another.

The ratio has the same meaning as proportion.

Ratios are represented in percentages, decimals, fractions, or with the ratio sign (:).

Another way to calculate it is to examine the ratio against the number of papayas he has.

Benjamin has 25 papayas, which is half of 50 (25/50).  This means he has half of the pears, which is 47 (94/2).

Papayas = 25

The ratio of papayas to pears = 50:94

For every 50 papayas Benjamin has, he has 94 pears.

The number of pears he has = 47 (25/50 x 94)

Thus, if Benjamin has 25 papayas, given the ratio of papayas to pears as 50:94, he has 47 pears.

Answer:

One geranium is $3

Step-by-step explanation:

Let r = roses and g = geraniums

14r + 8g = 122

12r + 12g = 120

Multiply first equation by -3 and the second by 2 (we are trying to get terms that cancel when we add the two equations)

-42r - 24g = -366

+24r + 24g = 240

Add

18r = 126

r = 7, so one rose is $7

Put this into either of the original equations

14(7) + 8g = 122

98 +8g = 122

8g = 24

g = 3, so one geranium is $3

The items that you can add with not breaking the weight limit are:

The hair dryer, the souvenir, the boots, the boots and the souvenir, and the hair dryer and the souvenir.

The maximum weight allowed is 50 pounds, and you already have 44.9 pounds, then the weight you can add is:

50lb - 44.9lb = 5.1lb

Now, the items that you have are:

2.5 lb hair dryer.

1.3 lb souvenir.

3.6 lb pair of boots.

The only things that you can't add together are the hair dryer and the boots, because the weight adds up to:

Which is more than the 5.1lb left that you have.

The gestation period of humans ​ is​ 309.23% percent longer than the gestation period of dogs.

Percentage is the fraction out of an amount that is expressed as a number out of hundred. Percentage is a measure of frequency. The sign used to represent percentages is %. In order to convert a number to percentage, express the number as a fraction and multiply by 100.

Percent of gestation period = (difference in the gestation period of dogs and humans / gestation period of humans) x 100

[(266 - 65) / 56] x 100

(210 / 65) x 100 = 309.23%

The area of the given circle is 36.298 cm square.

Here, we are given that f is the function that determines the area of a circle (in square cm) that has a radius of r cm.

The area of a circle is given the the formula as follows-

area of a circle = πr^2

⇒ f(r) = πr^2

The value of π is approximately 3.14

⇒ f(r) = 3.14r^2

Now, we are given that the radius of a circle is 3.4 cm.

Thus, its area will be-

f(3.4) = 3.14 × 3.4 × 3.4

= 3.14 × 11.56

= 36.298

The interval at which the function x³ + 3x² - 4x - 12 increases is

x ∈ (- ∞, - 2.5) ∪ (0.5, ∞).

We have,

x³ + 3x² - 4x - 12

We need to draw a graph to see at which interval the graph is increasing.

The graph is given below.

We see that the graph is increasing from x = -∞ to x = -2.5 and from  x = -2.5 it decreases till x = 0.5 and again from x = 0.5 it increases to x = ∞.

So we can write the interval as:

x ∈ (- ∞, - 2.5) and  x ∈ (0.5, ∞)

We can write it as one single interval as:

S = (- ∞, - 2.5) ∪ (0.5, ∞)

Using the relation between velocity, distance and time, it is found that a rate of 102 km/h is needed for the rest of the trip to achieve the desired rate for the entire trip.

Velocity is distance divided by time, that is:

v = d/t.

For the first 120 km, the rate is of 90 km/h, hence the parameters are given as follows:

d = 120, v = 90.

Hence the time is given by:

90 = 120/t1

t1 = 120/90

t1 = 1.33 hours.

For the second part of the trip, the parameters are given as follows:

t = 1.25, v = 64.

The time is 1.25 hours because 15 minutes is one fourth(15/60) = 0.25 of an hour.

Hence the distance found as follows is:

64 = d/1.25

d = 1.25 x 64

d = 80

The distance for the first two parts is given by:

120 + 80 = 200 km.

This is equivalent to 7/8 of the trip, hence the total distance is:

7/8d = 200

d = 200 x 8/7

d = 228.57 km.

For a rate of 80 km, we have that the time has to be of:

80 = 228.57/t

t = 228.57/80

t = 2.86 hours.

The time of the first two parts is:

1.33 + 1.25 = 2.58 hours.

2.86 - 2.58 = 0.28 hours.

Hence the last 228.57 - 200 = 28.57 km have to be traveled in 0.28 hours, for a rate of:

v = 28.57/0.28 = 102 km/h.

A rate of 102 km/h is needed for the rest of the trip to achieve the desired rate for the entire trip.

The two values of y after factorizing the given quadratic equation are 0, -0.5

The given equation is quadratic as the order of the equation is 2. In a quadratic equation with a single variable, the variable will have two different values which satisfy the equation. These values of the variable can be real and different, real and equal, or imaginary.

So, there will be two values of y.

Consider the given equation,

10y^2 + 12y = 7y

10y^2 +12y - 7y = 0

10y^2 + 5y = 0

Since the coefficients of y and y^2 are both multiples of 5,

5*(2y^2 + y) = 0

2y^2 + y = 0

Taking y as a common factor,

y*(2y+1) = 0

Now, we get two cases,

y = 0 or 2y + 1 = 0 => y = -(1/2) = -0.5

Therefore, y = 0 or y = -0.5

Answer:

An equivalent numerical expression with whole-

number exponent using these laws can be written as:

1) 2² × 2³ = 2^5     => using product of Powers

2) 2² × 3² = (2×3)² = 6²      => using power of a Product

3) (2²)³ = 2^6      => using power of a power

Step-by-step explanation:

First of all, let us understand some terms like;

1) Exponentiation: It is the mathematical process of raising one integer to the power of another. The base is the first integer, while the exponent is the second.

2) Power: A power is a phrase that depicts the same component being multiplied repeatedly.

3) Exponent: The number of times the base is used as a factor is represented by the exponent.

Now, let us understand the 7 Laws of Exponents;

1) a^m × a^n = a^(m+n)   => Product With the Same Bases

2) a^m / a^n = a^(m-n)    => Quotient with Same Bases

3) (a^m)^n = a^(m×n)    => Power Raised to a Power

4) a^n × b^n = (ab)^n    => Product to a Power

5) a^n / b^n = (a/b)^n    => Quotient to a Power

6) a^0 = 1     => Zero Power

7) a^(-m) = 1/a^m    => Negative Exponent Rule

Furthermore, an equivalent numerical expression with whole-

number exponent using these laws can be written as:

1) 2² × 2³ = 2^5     => using product of Powers

2) 2² × 3² = (2×3)² = 6²      => using power of a Product
