Answer:

Step-by-step explanation:

[tex]\frac{1}{4}b+6=16[/tex]

Subtract 6 from both sides,

[tex]\frac{1}{4}b+6-6=16-6\\\\\frac{1}{4}b=10\\\\b=10*4\\b=40[/tex]

Answer:

40 beads

Step-by-step explanation:

We want to find how many beads, b are being used

1/4b+6=16

To do this, we have to solve for b, by getting b by itself.

First, move all the constants to the same side. Subtract 6 from both sides, since it is being added to 1/4b.

1/4b+6-6=16-6

1/4b=10

Next, divide both sides by 1/4, or multiply both sides by the reciprocal of 1/4.

To find the reciprocal, flip the numerator (top number) and denominator(bottom number)

1/4–> 4/1

4/1*1/4b=10*4/1

The 1/4 will cancel, leaving us with:

b=10*4/1

b=40

Answer:

a primit 36 ​​corect ane 4 în mod greșit

Step-by-step explanation:

În această întrebare, ne preocupăm să calculăm numărul de răspunsuri corecte și de răspunsuri greșite pe care elevul le-a dat.

În primul rând, începem prin atribuirea de variabile.

Numărul de răspunsuri corecte să fie x în timp ce numărul de răspunsuri greșite să fie y

Deoarece există 40 de probleme în total, aceasta înseamnă că adăugarea ambelor este egală cu 40 matematic,

x + y = 40. ••• (i)

Acum să trecem la partea complicată. Fiecare răspuns corect = +7. Răspunsul corect total este astfel + 7x Fiecare răspuns greșit este = -5. Răspunsul total greșit este astfel -5y Punct total marcat = 232 Aceasta

înseamnă că; 7x -5y = 232 ••••••••• (ii)

De la i, putem spune y = 40 -x să punem acest lucru în ecuație

ii 7x -5 (40-x) = 232

7x - 200 + 5x = 232

12x = 232 + 200 12x = 432 x = 432/12 x = 36 Deoarece y = 40 - x y = 40 - 36 y = 4

The slope of the line passing through the given points (-1, 4) and (1, -2) is -3.

Given the following points:

To find the slope of the line passing through the given points (-1, 4) and (1, -2):

The slope of a line is simply the gradient of a line and it is typically used to describe both the direction and steepness of an equation of a straight line.

Mathematically, the slope of a line is given by the following formula;

[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

The Frequency table is shown below and the first Histogram is correct Histogram.

A frequency table is just a two-column "t-chart" or table that lists all of the potential outcomes and their corresponding frequencies as seen in a sample.

We have the data:

Ages of riders: 42, 14, 19, 30, 49, 48, 16, 24, 38, 53, 24, 15, 18, 20, 25, 11, 18, 49, 54, 20, 17, 26, 37, 15, 28.

So, the Frequency table is

Interval            Frequency

10−19                   9

20−29                 7

30−39                 3

The completed frequency table is shown below.

The correct histogram of the data is: A. histogram A.

In Mathematics and Statistics, a frequency table can be used for the graphical representation of the frequencies or relative frequencies that are associated with a categorical variable or data set.

In a frequency distribution table, all classes must have the same class width. In this context, we would develop a grouped frequency table by using a class width of 10 as follows;

Interval            Frequency

10 − 19                   9

20 − 29                 7

30 − 39                 3

40 − 49                 4

50 − 59                 2

In conclusion, we can logically deduce that only histogram A correctly represents the ages of the people who ride the new roller coaster during a fifteen-minute period.

Answer:

The toy's maximum height is [tex]10.12\ \text{feet}[/tex].

Step-by-step explanation:

The equation that models the toy's height in feet from the ground at t seconds after  he threw it is given by :

[tex]h = -2t^2 + 7t + 4[/tex] .....(1)

It is required to find the toy's maximum height. For maxima or minima, put

[tex]\dfrac{dh}{dt}=0[/tex]

Plugging the value of t in above equation,

[tex]\dfrac{d(-2t^2 + 7t + 4)}{dt}=0\\\\-4t+7=0\\\\t=\dfrac{7}{4}\\\\t=1.75\ s[/tex]

Now put t = 1.75 s in equation (1) such that,

[tex]h = -2(1.75)^2 + 7(1.75) + 4\\\\h=10.12\ \text{feet}[/tex]

So, the toy's maximum height is [tex]10.12\ \text{feet}[/tex].

The toy's maximum height is 10.12 feet.

Since the nephew is standing on his deck, which is 4 feet off the ground. He tosses his toy up into the air at an initial velocity of 7 feet per second. The equation is [tex]h = -2t^2 + 7+ 4[/tex]

So first we have to determine the t i.e.

[tex]d(-2t^2 + 7 +4) \div dt = 0\\\\-4t + 7 = 0\\\\ t = 7\div 4[/tex]

t = 1.75 s

Now

the height should be

[tex]= -2(1.75)^2 + 7(1.25)+ 4[/tex]

= 10.12 feet.

hence, The toy's maximum height is 10.12 feet.

Of students in the sample, 90/200 fraction of the students were male.

Number of male students =90

Number of female students =110

So, total students = 90+110 =200

A fraction is a rational number that is not a whole number.

Fraction of students who were male = male students/ total students

Fraction of students who were male =90/200

So, 90/200 fraction of the students were male.

Final answer:

Two pumps working together will fill a tank in 12/7 hours, calculated by adding their rates of filling the tank and taking the inverse of the sum.

Explanation:

When two pumps are used together to fill a tank, the time it takes can be found by adding their rates of work and then finding the inverse of the sum. The first pump can fill the tank in 4 hours, which means its rate is 1/4 of the tank per hour. The second pump can fill the same tank in 3 hours, implying a rate of 1/3 of the tank per hour. When both pumps work together, their combined rate is (1/4 + 1/3) = (3/12 + 4/12) = 7/12 of the tank per hour.

To find the time taken to fill the tank jointly, we take the inverse of the combined rate: 1 / (7/12), which equals 12/7 hours. Therefore, using both pumps together, it will take 12/7 hours to fill the tank.

Every second, the number of harmful bacteria remaining in the body decays by a factor of approximately .

To determine the rate of change in the number of harmful bacteria remaining in the body every second, we need to convert the time in the given function from minutes to seconds. The function provided is

⇒ [tex]H_{minute}[/tex](t) = 500,000,000 · [tex](0.2)^t[/tex].

A minute has 60 seconds, so we need to express the decay factor for a second. By letting t = [tex]t_{seconds}[/tex] ÷ 60, we can rewrite the function in terms of seconds:

⇒ [tex]H_{second}[/tex](t) = 500,000,000 · [tex](0.2)^\frac{t}{60}[/tex].

For every passing second, the decay factor is [tex](0.2)^\frac{1}{60}[/tex]. Using a calculator, we find:

⇒ [tex](0.2)^\frac{1}{60}[/tex] ≈ 0.98855,

rounded to two decimal places.

Therefore, every second, the number of harmful bacteria remaining in the body decays by a factor of approximately 0.99.

Answer: 40

Step-by-step explanation: When you're asked to solve for x in an equation, what you're really being asked to do is get x by itself on one side of the equation.

In this problem since 10 is being added to x, in order to get x by itself, we must subtract 10 from the left side of the equation and when we subtract 10 from the left side of the equation, remember that we must also subtract 10 from the right side of the equation.

So on the left, 10 - 10 cancels out and

on the right, 50 - 10 simplifies to 40.

So x = 40.

Answer:

x = 40

Step-by-step explanation:

To solve for x, we must get it by itself. To do this, we have to subtract 10 from the left and right side of the equation.

Equation: x + 10 - (10) = 50 - (10)

This will cancel out the 10 on the left side (as 10 - 10 = 0) of the equation and leave you with the answer, x = 40.

Final answer:

To find the solution, add 91, 129, and 16 to get a sum of 236. Then divide this sum by 44 to get approximately 5.364.

Explanation:

To solve the given problem, we need to perform two steps: first, add the numbers together; second, divide the sum by 44.

Add 91, 129, and 16 together.

Divide the sum by 44.

We start by adding the numbers:

91 + 129 + 16 = 236

Next, we divide the sum by 44:

236 ÷ 44 = 5.363636...

The division yields a repeated decimal which we can round to a desired decimal place if necessary. In this context, we'll keep it as is or round it to the nearest thousandth, which would be approximately 5.364.
