Using each of the digits 0-6 only once, make two equivalent ratios

Mathematics
1 answer:
KengaRu [80]3 years ago
3 0

Answer:

The two equivalent ratios are 8:4 and 2:1

Step-by-step explanation:

The digits taken are 4 and 2.

Therefore, 4:2 = 4 x 2:2 x 2

So one equivalent ratio is 4:2 = 8:4

For the other equivalent ratio, 4:2 = 4 /2:2/2

Hence, the other equivalent ratio is 4:2 = 2:1

Finally, the two equivalent ratios are 8:4 and 2:1

A ratio obtained by multiplying or dividing the numerator and denominator of a given ratio by the same number is called an equivalent-ratio.

A ratio is a comparison of two quantities by division. Ratios describe a part-to-part comparison or a part-to-whole comparison. Ratios are written three ways: as a fraction, with a colon, and with the word “to.” The ratio for quantity a to quantity b is: a/b or a:b or a to b. Consequently, a ratio may be considered as an ordered pair of numbers, as a fraction with the first number in the numerator and the second as denominator, or as the value denoted by this fraction. Ratios of counts, given by (non-zero) natural numbers, are rational numbers, and may sometimes be natural numbers. When two quantities are measured with the same unit, as is often the case, their ratio is a dimensionless number. A quotient of two quantities that are measured with different units is called a rate.

new type of cell phone is being released to the public. The function below is used to predict f(t), the total sales in thousands
MrMuchimi

Answer:

40,000 units on the first day then 18% per week

Step-by-step explanation:

Exponential function:

An exponential function has the following format:

f(t) = f(0)(1+r)^{t}

In which r is the rate of change, as a decimal.

In this question:

The number of phones sold in thousands of units per day, in t weeks since the date of release, is:

f(t) = 40(1.18)^{t}

Since f(0) = 40, it solds 40,000 on the first week.

The rate of percentage increase is:

1 + r = 1.18

r = 0.18

So an increase of 0.18 = 18% a week.

So the correct option is:

40,000 units on the first day then 18% per week

The function y=px2−4x+qy=px2−4x+q in the x-y plane attains a minimum value. What is the value of xx? 1) p=2p=2 2) q=5
Leni [432]

Answer:

1

Step-by-step explanation:

Given function:

y = px² - 4x + q

To find the points of maxima or minima

\frac{dy}{dx} = 0

or

2px - 4 + 0 = 0

or

px = 2

or

x = [2 ÷ p]

at p = 2

x = 2 ÷ 2 = 1

To check for minima

\frac{d^2y}{dx^2} > 0

thus,

2p - 0 > 0

2p > 0

for positive value of p function is minimum at x = 1

2) at q = 5 also x = 1 as value of x is independent of q
