and 15kg of maize to the market. He sold
2½kg of millet 2¾kg of sorghum and 10kg of
maize. What was the total mass cereals that
remained?

A. 15¼ kg
B. 23kg
C. 8¼kg
D. 7¾kg

what's the solution to solve it?​

Answers

Answer:

D

Step-by-step explanation:

(3.25+4.75+15) =23

23- (2.5+2.75+10)

= 7.75

Millet: convert 2 1/2 to 4ths, and 3 1/4 to an improper fraction as well

2 1/2 = 5/2 = 10/4
13/4 -10/4 = 3/4 kg of millet left over

Sorghum:
4 3/4 - 2 3/4 = 2 kg of sorghum left over

Maize:
15kg - 10kg = 5kg left over

3/4 + 2 + 5 = 7 3/4 kg total

If 6(2x+1) is equal to -36-2x, what is the value of 3x

Answers

6(2x + 1) = -36 - 2x
12x + 6 = -36 - 2x
12x + 2x = -36-6
14x = -42
X = -3

Answer:

The value of 3x is -9

Step-by-step explanation:

Given Equation

[tex]6(2x + 1) = - 36 - 2x[/tex]

Step 1

Distribute 6 in the expression.

[tex]12x + 6 = - 36 - 2x[/tex]

Step 2

Combine like terms and solve the equation for x-term

[tex]12x + 2x = - 36 - 6 \\ 14x= - 42 \\ x = \frac{ - 42}{14} \longrightarrow \frac{ - 3}{1} \\ x = - 3[/tex]

But we want to know what is the value of 3x.

Step 3

Substitute the value of -3 in 3x.

[tex]3x = 3( - 3) \\ 3x = - 9[/tex]

Hence, the value of 3x is -9

The value of measure of angle F is,

⇒ ∠ F = 63°

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Triangle ABC and DEF are congruent.

Hence, Their corresponding angles are same.

So, We get;

⇒ ∠ A = ∠X

⇒ ∠B = ∠Y

⇒ ∠C = ∠Z

Here, ∠C = 63°

Hence, The value of measure of angle F is,

⇒ ∠ F = 63°

Thus, The value of measure of angle F is,

⇒ ∠ F = 63°

f(x) = X 1 - 4
-
3

Answers

Answer:

(0,-4)

Step-by-step explanation:

Given

[tex]f(x) = x^\frac{1}{3} - 4[/tex]

Required

Determine the critical numbers

[tex]f(x) = x^\frac{1}{3} - 4[/tex]

Differentiate:

[tex]f'(x) = \frac{1}{3}x^{\frac{1}{3} - 1}[/tex]

[tex]f'(x) = \frac{1}{3}x^{-\frac{2}{3}}[/tex]

Equate to 0

[tex]f'(x) = \frac{1}{3}x^{-\frac{2}{3}} = 0[/tex]

[tex]\frac{1}{3}x^{-\frac{2}{3}} = 0[/tex]

Multiply through by 3

[tex]3 * \frac{1}{3}x^{-\frac{2}{3}} = 0*3[/tex]

[tex]x^{-\frac{2}{3}} = 0[/tex]

[tex]x = 0[/tex]

Substitute 0 for x in [tex]f(x) = x^\frac{1}{3} - 4[/tex]

[tex]f(0) = 0^\frac{1}{3} - 4[/tex]

[tex]f(0) = 0- 4[/tex]

[tex]f(0) = - 4[/tex]

Hence, the critical point is: (0,-4)

Answers

Answer:

$55.96

Step-by-step explanation:

To find 30% of $79.95, we must multiply 79.95 by .3

We get 23.985, which can be rounded to the nearest 100th to get 23.99

So, 30% of $79.95 is $23.99

Now, we can just subtract to find the sale price.

$79.95 - $23.99 = $55.96

A new secretary has been given n computer passwords, only one of which will permit access to a computer file. Because the secretary has no idea which password is correct, he chooses one of the passwords at random and tries it. If the password is incorrect, he discards it and randomly selects another password from among those remaining, proceeding in this manner until he finds the correct password. What is the probability that he obtains the correct password on the second try? The third try?

Answers

Answer:

The answer is "[tex]\bold{\frac{1}{n}}[/tex]"

Step-by-step explanation:

Although n passwords were available and any time a wrong password is deactivated. Throughout the second try, if the secretary finds the right password, its input during the first attempt should be incorrect. Therefore, the likelihood is:

[tex]\to Pr= \frac{n-1}{n} \times \frac{1}{n-1} =\frac{1}{n}[/tex]

If n passwords were accessible and any time the wrong password is deactivated. Unless the delegate finds the right password on the three trials, the input should be incorrect during the first and second trials. Consequently, the likelihood is:

[tex]\to Pr= \frac{n-1}{n} \times \frac{n-2}{n-1} \times \frac{1}{n-2} =\frac{1}{n}[/tex]
