Answer:

0.4

Step-by-step explanation:

so, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)

if in two hours she and Marina can be done, then Marina will do 1(the whole job)-2/10 (twice as much as she can do in an hour)=0.8 of the job. So if Marina does 0.8 of the job in two hours, each hour she will do half of it: 0.4 - and this is the correct answer 

Answer:

12 cm

Step-by-step explanation:

The total surface area of the cone = area of base + area of curved surface

Subtract the base area from total area, that is

πrs = area - πr²

r is the radius and s the slant height

πrs = 417.8 - (π × 7²) = 263.86

Divide both sides by πr

s = [tex]\frac{263.86}{7\pi }[/tex] ≈ 12 cm

ANSWER

The x-coordinate of the solution to the system of equations is 1.

EXPLANATION

The given equations are:

y = -x - 2

and

y = 2x - 5.

We want to find the x-coordinate of the solution to the system of equations.

We equate the two equations to obtain an equation in x.

This implies that,

2x-5=-x-2

Group similar terms to obtain:

2x+x=-2+5

Simplify

3x=3

Divide both sides by 3.

x=1

The x-coordinate of the solution to the system of equations is 1

The solution to the system of equations y = -x - 2 and y = 2x - 5 is found by setting them equal to each other and solving for x, which yields the x-coordinate of the solution as 1.

To find the x-coordinate of the solution to the system of equations y = -x - 2 and y = 2x - 5, we can solve the equations simultaneously since they are both linear equations. Here are the steps to finding the solution:

So, the x-coordinate of the solution to the system of equations is 1.

In an isosceles right triangle, the hypotenuse is larger than the sides by a factor of the square root of 2.

So, if the hypotenuse is 8 then the sides are 8 / (sq root of 2) = 5.6568542495

Step-by-step explanation:

Answer:

A. y=-3x + 29

Step-by-step explanation:

The slope shows up in the equation as the coefficient of x. Only answer choice A has an x-coefficient of -3. It also happens to describe a line that goes through (7, 8).

y = -3x +29

___

Check

y = -3·7 +29 = -21 +29 = 8 . . . . as required

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 3, so

y = - 3x + c ← is the partial equation of the line

To find c substitute (7, 8) into the partial equation

8 = - 21 + c ⇒ c = 8 + 21 = 29

y = - 3x + 29 → A

Answer:

37

Step-by-step explanation:

Pamela's age can be repesented with the variable, p .

Pamela is 11 years younger than Jerry. Jerry's age can be represented with the expression p + 11.

So,

Pamela: p

Jerry: p + 11

If their total, combined age is 63, the following equation can be used to represent their ages.

p + (p + 11) = 63

Now, solve.

p + (p + 11) = 63

p + p + 11 = 63

2p + 11 = 63

2p = 52

p = 26

Now, remember that 26 is how old Pamela is. We're looking for Jerry's age.

We established before that Jerry's age can be represented with the expression p + 11.

We know what p is, so substitute the value of p into the equation.

p + 11

26 + 11

37

So, Jerry is 37 years old.

If you'd like to double check your answer, add 37 [Jerry's age] and 26 [Pamela's age] and you get 56.

I hope this helps you!!! :)

The sides of the transformed figure A'B'C'D' describes A'D' is congruent to A'B' . The correct answer is option A

Translating a figure ABCD down by 6 units results in a congruent figure A'B'C'D', meaning the sides of the transformed figure are of the same length and angles as the original.

When a figure is translated, all of its sides remain parallel and congruent to the corresponding sides of the original figure. Therefore, the sides of the transformed figure A'B'C'D' are all parallel to the corresponding sides of the original figure ABCD.

In particular, we can see that A'D' is parallel to A'B' because they are both horizontal lines. Additionally, we can see that A'D' is congruent to A'B' because they are both the same length.

Therefore, the correct answer is option A. A'D' || A'B'.

Answer:

x = 18.

Step-by-step explanation:

x / 1.2 = 15

To isolate x we multiply both sides of ther equation by 1.2:

x = 15 * 1.2

x =  18 (answer).

For this case we must find the value of the variable "x" of the following equation:

[tex]\frac {x} {1.2} = 15[/tex]

To do this, we must multiply both sides of the equation by "1.2":

[tex]\frac {x} {1.2} * 1.2 = 15 * 1.2\\x = 18[/tex]

Thus, the value of the variable x is 18.

Answer:

[tex]x = 18[/tex]

Easily you can try each formula with x=-2

because we know f(-2)=-1

So ,in this way D is correct Only!!

Answer:

D) f(x) = (x + 2)³ -1.

Step-by-step explanation:

Given  : the graph of f(x), shown below in pink, has the same shape as the graph of g(x)=x^3, shown in gray.

To find :  which of the following is the equation for f(x).

Solution : We have given

Graph of f(x) is pink and graph of  g(x) is gray.

We can see graph of f(x) is shifted to 2 unit left and 1 unit down

Because  gray is at (0 ,0 ) and pink is at ( -2,-1)

By the transformation rule  f(x) →→ f(x+h) -k.

It shows that graph is shifted  to left by h unit and shifted down by k unit.

Then the equation of pink graph is :

f(x) = (x + 2)³ -1.

Therefore,D) f(x) = (x + 2)³ -1.

Answer:

Find the Greatest Common Factor (GCF)

GCF = 2xy

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

2xy(8x^3y/2xy + -8x^2y/2xy + -30xy/2xy)

Simplify each term in parenthesis

2xy(4x^2 - 4x - 15)

Split the second term in 4x^2 - 4x - 15 into two terms

2xy(4x^2 + 6x - 10x - 15)

Factor out common terms in the first two terms, then in the last two terms;

2xy(2x(2x + 3) -5(2x + 3))

Factor out the common term 2x + 3

= 2xy(2x + 3)(2x - 5)

Answer:

C. 19.23%

Step-by-step explanation:

We simply have to sum up all the times he had a six then divide that by all the times he rolled the die.

Total times he got 6: 5 + 3 + 11 + 11 = 30

Total times he rolled the die: 39 + 21 + 55 + 41 = 156

The experimental probability is then 30 / 156 = 19.23%

It's a bit higher than expected (1/6 or 16.66%), but the sampling is relatively small.  If he were to throw it a thousand times, he'd probably be much close to the theoretical probability.

Answer:

[tex]\large\boxed{A.\ \dfrac{1}{x^2y^2}}[/tex]

Step-by-step explanation:

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

[tex]\text{Used}\\\\a^0=1\ \text{for all real numbers except 0}\\\\a^{-n}=\dfrac{1}{a^n}[/tex]

The first option is correct: we have

[tex]\left(k^{\frac{1}{8}}\right)^{-1} = \dfrac{1}{k^{\frac{1}{8}}} = \dfrac{1}{\sqrt[8]{k}},\quad \left(k^{-1}\right)^{\frac{1}{8}} = \left(\dfrac{1}{k}\right)^{\frac{1}{8}} = \dfrac{1}{\sqrt[8]{k}}[/tex]

The second option is also correct, because it simply applies the definition

[tex]k^{\frac{1}{n}} = \sqrt[n]{k}[/tex]

The third option is also correct, because it applies the rule

[tex](a^b)^c = a^{bc}[/tex]

The expressions equivalent to (k^(1/8))^(-1) are (k^(-1))^(1/8) and k^(-1/8), matching options a and c from the given choices. These are determined by correctly applying the exponent multiplication rule.

The student is dealing with an expression involving exponents and radicals, specifically focused on understanding the rules for combining and simplifying these expressions. The expression in question is (k^(1/8))^(-1), which we'll simplify in a step-by-step fashion.

The rule of exponents we need to apply here is (a^m)^n = a^(m*n). When applying this rule to the given expression we get:

(k^(1/8))^(-1) = k^(1/8 * -1)

Simplify the exponent:

k^(1/8 * -1) = k^(-1/8)

So, the equivalent expression is:

k^(-1/8)

Now let's examine the choices given:

[tex] \frac{3.4}{5.1} = 0.666667[/tex]

Your answer is 0.6 repeating

For this case we must evaluate [tex]x = 2[/tex] in each of the inequalities and verify if the inequality is met or not:

It is not fulfilled!

Option B:

[tex]7x-10 <11\\7 (2) -10 <11\\14-10 <11\\4 <11[/tex]

Is fulfilled!

Option C:

[tex]14x + 10 <37\\14 (2) +10 <37\\28 + 10 <37\\38 <37[/tex]

It is not fulfilled!

Option D:

[tex]15x-18 <12\\15 (2) -18 <12\\30-18 <12\\12 <12[/tex]

It is not fulfilled!

So, option B is correct, inequality is met

ANswer:

Option B

Final answer:

Upon substituting x with 2 in each of the given inequalities, option B (7x − 10 < 11) is the only true inequality, making it the correct answer.

Explanation:

To determine which inequality is true for x = 2, let's substitute x with 2 in each option:

Therefore, option B) 7x − 10 < 11 is the true inequality when x = 2.

8 + 4 (2x+7) = 2 (2+6x), 4 (2x+7) + 8 = 2 (6x+2), (4 x 2x + 4x7) + 8 = 2 (6x+2)

x = 9

Answer:

a) Samuel has a better credit score, so his interest rate is lower.

Step-by-step explanation:

Alan and Samuel both are same age and make same amount of money.

They both have a 30-year mortgage. But Alan pays 5 percent interest, while Samuel only pays 3.5 percent.

There correct answer here will be - Samuel has a better credit score, so his interest rate is lower.

When a person has a good credit rating, that means he has never defaulted any payment and has always paid his loan on time. He must be a trusted customer for the bank that is why he got a lower interest rate than Alan.

Answer: Option B.

[tex]b=\frac{5}{4}[/tex]

Step-by-step explanation:

If a varies directly with b then when a increases b it also increases by a factor k.

Then we can write that

[tex]a = kb[/tex]

We know that when a = 28 then b = 7. So

[tex]28 = k * 7[/tex]

[tex]k=\frac{28}{7}[/tex]

[tex]k=4[/tex]

Therefore the equation of proportionality is:

[tex]a=4b[/tex]

So when [tex]a=5[/tex]  then:

[tex]5=4b\\\\b=\frac{5}{4}[/tex]

ANSWER

The correct choice is B.

EXPLANATION

If 'a' varies directly as 'b' then we write the equation of variation,

[tex]a = kb[/tex]

Where k is the constant of variation.

We have that a = 28 when b = 7.

This implies that,

[tex]28= 7k[/tex]

[tex]k = 4[/tex]

The equation now becomes

[tex]a = 4b[/tex]

When we a=5, we have

[tex]5 = 4b[/tex]

[tex]b = \frac{5}{4} [/tex]

The correct answer is B
