Hey there!

The formula is: y2 - y1 / x2 - x1

y2 = 11

y1 = 5

x2 = 4

x1 = 1

Equation: 11 - 5 / 4 - 1

11 / 5 = 6

6 / 4 - 1

4 - 1 = 3

6/3 = 2

Step-by-step explanation:

Via needs 2 1/2 bags of grass seed

The number of bags of grass seed that Amanda should use to spread her yard is 16.65 bags, meaning she needs to buy not more than 17 bags, using mathematical operations.

The basic mathematical operations we use are subtraction, addition, division, and multiplication.

In this situation, we use the division operation.

The division operation involves four parts:

The dividend (numerator or the number being divided).

The divisor (denominator or the number dividing).

The quotient (the result of the division operation).

The equal symbol (that shows that two values are equal).

The area of the yard = 4,995 ft²

1 yard = 3 feet

Area of the yard = 1,665 square yards(4,995/3)

The number of bags per 100 square yards = 1 bag

For 1,665 square, the number of bags = 16.65 bags (1,665 ÷ 100)

Thus, Amanda requires 16.65 bags of the grass seed for her yard.

complete question:

Amanda is spreading new grass seed on her yard. The area of her yard is 4,995 square feet. The instructions on the bags of grass seed say that one bag of seed should be used for every 100 square yards. How many bags of grass seed should Amanda use?

Answer:

36 Sq cm

Step-by-step explanation:

Area of the trapezoid

[tex] = \frac{1}{2} \{8 + (4 + 8 + 4) \} 3\\ \\ = \frac{1}{2} \{8 + 16 \} 3\\ \\ = \frac{1}{2} \times 24 \times 3\\ \\ = 12 \times 3 \\ \\ = 36 \: {cm}^{2} [/tex]

Using the t-distribution, it is found that:

At the null hypotheses, it is tested if the mean is of 11 cm, that is:

[tex]H_0: \mu = 11[/tex]

At the alternative hypotheses, it is tested if the mean is greater than 11 cm, hence:

[tex]H_1: \mu > 11[/tex].

The test statistic is given by:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

For this problem, the values of the parameters are given as follows:

[tex]\overline{x} = 11.08, \mu = 11, s = 0.21, n = 53[/tex]

Hence the value of the test statistic is:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{11.08 - 11}{\frac{0.21}{\sqrt{53}}}[/tex]

t = 2.77.

Using a calculator, with t = 2.77 and 53 - 1 = 52 df, the p-value is of 0.0039.

Since the p-value is less than 0.01, sufficient evidence exists that the length of bolts is actually greater than the mean value at a significance level of 0.01.

Answer: -10w-20

Step-by-step explanation:

Because the number is in front of the bracket you have to times everything inside the bracket by the number on the outside.

5x-2w= -10w (you would basically do 5x-2 which is -10 then put the w on the end of it).

5x-4= -20

Then put it together so -10w-20

Answer:

c) inversely

Step-by-step explanation:

In Mathematics an inverse relationship can be defined as a relationship between two variables, in which an increase in the value of one variable leads to a decrease in the value of the other variable i.e as the value of one variable becomes large, the value of the other variable becomes small.

Mathematically, an inverse relationship is given by the formula;

A = K/B

Where;

A and B are the variables.

K is the constant of proportionality.

Hence, if an increase in one quantity brings about a corresponding decrease in the other and vice versa, then the two quantities vary inversely.

A) r=∛(6v)/[tex]\pi[/tex]

Step-by-step explanation:

v=1/6[tex]\pi[/tex]r³

v÷1/6=[tex]\pi[/tex]r³

(when dividing by a fraction, invert and multiply)

6v=[tex]\pi[/tex]r³

6v÷[tex]\pi[/tex]=r³

(6v)/[tex]\pi[/tex]=r³

take the cube root of both sides

∛(6v)/[tex]\pi[/tex]=∛r³

∛(6v)/[tex]\pi[/tex]=r

Answer:

Even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.

Step-by-step explanation:

Given that you invested $ 3000 between two accounts paying 4% and 8% annual interest respectively, to determine how much was invested at each rate if the total interest eamed for the year was $ 520, the following calculation must be performed:

3000 x 0.04 + 0 x 0.08 = 120

1500 x 0.04 + 1500 x 0.08 = 180

3000 x 0.08 + 0 x 0.04 = 240

Thus, as can be seen, even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.

Step-by-step explanation:

79/25 simplified= 3 4/25

Answer:

3 4/25

How:

3.16 as a fraction = 79/25

79/25 simplified = 3 4/25

Step-by-step explanation:

substitute 2 into x

1. (u ○ w)(2)

u(w(x))

= 4(-5x+1)+2

= 4(-5.2+1)+2

= 4(-9)+2

=-34

2. (w ○ u)(2)

w(u(x))

= -5(4x+2)+1

= -5(4.2+2)+1

= -5(10)+1

= -49

Answer:

y=-1/4x+21/4

Step-by-step explanation:

Slope=-2/8=-1/4

y=-1/4x+b

4=-1/4(5)+b

4=-5/4+b

5.25=b

21/4=b

Answer (assuming it can be written in slope-intercept form):

[tex]y = \frac{7}{9} x+\frac{17}{9}[/tex]

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:

[tex]m = \frac{(5)-(-2)}{(4)-(-5)} \\m = \frac{5+2}{4+5} \\m = \frac{7}{9}[/tex]

So, the slope is [tex]\frac{7}{9}[/tex].

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.

Since [tex]m[/tex] represents the slope, substitute [tex]\frac{7}{9}[/tex] for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, choose from any one of the given points (it doesn't matter which one, either way the result equals the same thing) and substitute its x and y values into the formula as well. (I chose (4,5), as seen below.) From there, isolate y to place the equation in slope-intercept form ([tex]y = mx + b[/tex] format) and find the following answer:

[tex]y-(5) = \frac{7}{9} (x-(4))\\y-5 = \frac{7}{9} (x-4)\\y -5=\frac{7}{9} x-\frac{28}{9}\\y = \frac{7}{9} x-\frac{28}{9} +\frac{45}{9}\\y = \frac{7}{9} x+\frac{17}{9}[/tex]
