Irma picked 5/8 of a bushel and Matthew picked half as many. How many bushels did Matthew pick?

So a basic function is y=mx+b where m is a rate and b is the constant. His goal is 150 so y is 150 and the rate of his baking is 16 so m is 16, finally he has already 22 done so 22 remains constant. Plugging all these in you should get the following equation:

150=16x+22

Final answer:

Hou's goal is to bake at least 150 cookies, and he has already baked 22. If he bakes an average of 16 cookies every half hour, the equation representing the total cookies baked is Cookies baked = 16t + 22. The inequality to ensure he meets his goal is 16t + 22 >= 150.

Explanation:

Hou has set a goal to bake 150 cookies for a fundraiser and has already baked 22 cookies. He averages about 16 cookies every half hour. To represent this situation mathematically, we can use an equation related to the number of cookies baked over time.

Let's define the variable t to represent the number of half-hour segments Hou bakes. The total number of cookies Hou will have baked after t half-hour segments can be calculated by multiplying the number of segments by the average number of cookies baked in each half-hour segment and then adding the 22 cookies already baked.

The equation representing this situation is:

Cookies baked = 16t + 22

Hou's goal is to bake at least 150 cookies, so we create an inequality to represent the situation:

16t + 22 ≥ 150

The answer is:

[tex](3xy-1)(4xy+2)=12(xy)^{2}+2xy-2[/tex]

or

[tex](3xy-1)(4xy+2)=12x^{2}y^{2}+2xy-2[/tex]

To solve the problem and identify the resultant expression, we need to apply the distributive property, and the, add or subtract like terms.

Describing the distributive property:

[tex](a+b)(c+d)=a*c+a*d+b*c+b*d[/tex]

Remember, like terms are the terms that share the same variable and same exponent, for example:

[tex]a^{2} +3a^{2}+a^{3}=4a^{2}+a^{3}[/tex]

We were able to add only the terms that have the same exponent (2).

We are given the expression:

[tex](3xy-1)(4xy+2)[/tex]

Now, solving we have:

[tex](3xy-1)(4xy+2)=(3xy*4xy)+(3xy*2)-(1*4xy)-2\\\\(3xy*4xy)+(3xy*2)-(1*4xy)-2=12(xy)^{2}+6xy-4xy-2\\\\12(xy)^{2}+6xy-4xy-2=12(xy)^{2}+2xy-2[/tex]

Hence, we have that:

[tex](3xy-1)(4xy+2)=12(xy)^{2}+2xy-2[/tex]

or

[tex](3xy-1)(4xy+2)=12x^{2}y^{2}+2xy-2[/tex]

Answer:

D 81 pi units^2

Step-by-step explanation:

The circumference of a circle  is given by

C = 2 * pi *r

18 pi = 2 * pi *r

Divide each side by 2 * pi

18 pi / (2 pi) = 2 pi * r/ (2 pi)

Answer:

which fraction equals -9/16--------->An equivalent fraction is nothing but, when the numerator and denominator of the fraction are equal when written in lowest terms. The fraction 3/9 is equal to 1/3 when reduced to lowest terms.

Step-by-step explanation:

-18/32, -27/48 are the fractions which are equivalent fractions of -9/16.

Numerical value that is a part of a whole is called as Fraction. It is evaluated by dividing a whole into number of parts.

We have to find an equivalent fraction of -9/16

To find the equivalent fraction  multiply both the numerator and denominator by the same number.

Multiply both the denominator and numerator of -9/16 by 2

(-9 x 2)/(16 x 2)

= -18/32

Now let us multiply both the numerator and denominator of -9/16 by 3, we get:

(-9 x 3)/(16 x 3)

= -27/48

Therefore,  -18/32, -27/48 are the fractions which are equivalent fractions of -9/16.

About $290.83.

Hope this helps!

The police officer will earn approximately $290.83 more each month in his second year, as his annual salary will raise from $26,400 to $29,890.

In this scenario, we are dealing with a salary raise and how it affects the overall monthly income. The first year, the police officer is earning $2,200 per month, which translates to an annual salary of $26,400 (since there are 12 months in a year, you can simply multiply the monthly income by 12 to find this). The second year, his annual salary will be raised to $29,890.

To see how much more they will be making a month, subtract the first year's annual salary from the second year's total ($29,890 - $26,400 = $3,490). This is the total raise for the year, but we want to find out how much more the officer will be making a month. Since the raise is distributed over 12 months, simply divide this total by 12 to get the answer. $3,490 ÷ 12 = approximately $290.83. So, the police officer will be making around $290.83 more each month in the second year.

The answer is:

The general form of the circle is:

[tex]x^{2} -2x+y^{2} +4y=0[/tex]

We are given the standard form of a circle, so, to calculate the general form, we need to solve notable products.

We must remember the way to solve the notable product:

[tex](a+b)^{2}=a^{2}+2ab+b^{2} \\\\(a-b)^{2}=a^{2}-2ab+b^{2}[/tex]

So,

We are given the equation:

[tex](x-1)^{2}+(y+2)^{2}=5[/tex]

Then, solving the notable products, and adding/subtracting like terms, we have:

[tex]x^{2} -2*1x+1+y^{2}+2*2y+4=5\\x^{2} -2x+1+y^{2} +4y+4=5\\\\x^{2} -2x+y^{2} +4y+1+4-5=0\\\\x^{2} -2x+y^{2} +4y=0[/tex]

Hence,  have that the general form of the circle is:

[tex]x^{2} -2x+y^{2} +4y=0[/tex]

Have a nice day!

The answer is:

The center of the circle is located on the point (-9,-2) and the radius is 6 units.

To solve the problem, we need to use the given equation which is in the general form.

We are given the circle:

[tex]x^{2}+y^{2}+18x+4y+49=0[/tex]

We know that a circle can be written in the following form:

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

Where,

h is the x-coordinate of the center of the circle

k is the y-coordinate of the center of the circle

r is the radius of the circle.

So, to find the center and the radius, we need to perform the following steps:

- Moving the constant to the other side of the equation:

[tex]x^{2}+y^{2}+18x+4y=-49[/tex]

- Grouping the terms:

[tex]x^{2}+18x+y^{2}+4y=-49[/tex]

- Completing squares for both variables, we have:

We need to sum to each side of the equation the following term:

[tex](\frac{b}{2})^{2}[/tex]

Where, b, for this case, will the coefficients for both terms that have linear variables (x and y)

So, the variable "x", we have:

[tex]x^{2} +18x[/tex]

Where,

[tex]b=18[/tex]

Then,

[tex](\frac{18}{2})^{2}=(9)^{2}=81[/tex]

So, we need to add the number 81 to each side of the circle equation.

Now, for the variable "y", we have:

[tex]y^{2} +4y[/tex]

Where,

[tex]b=4[/tex]

[tex](\frac{4}{2})^{2}=(2)^{2}=4[/tex]

So, we need to add the number 4 to each side of the circle equation.

Therefore, we have:

[tex](x^{2}+18x+81)+(y^{2}+4y+4)=-49+81+4[/tex]

Then, factoring, we have that the expression will be:

[tex](x+9)^{2}+(y+2)^{2}=36[/tex]

- Writing the standard form of the circle:

Now,  from the simplified expression (after factoring), we can find the equation of the circle in the standard form:

[tex](x+9)^{2}+(y+2)^{2}=36[/tex]

Is also equal to:

[tex](x-(-9))^{2}+(y-(-2))^{2}=36[/tex]

Where,

[tex]h=-9\\k=-2\\r=\sqrt{36}=6[/tex]

Hence, the center of the circle is located on the point (-9,-2) and the radius is 6 units.

Answer:

30 gms

Step-by-step explanation:

half life time means time taken for material to become half of its quantity

120 gms will become 60 gms in 10 mins

then in 20 mins, it will be 30 gms

After 20 minutes 30 grams amount of radioactive form of nitrogen left.

Given

The total amount radioactive form of nitrogen = 120 grams

The time is taken for the radioactivity of a specified isotope to fall to half its original value:

The formula is used to calculate half-life is;

[tex]\rm Half \ life = \dfrac{Amount \ of \ substance}{2}[/tex]

The half-life of the nitrogen after 10 minutes;

[tex]\rm Half \ life = \dfrac{Amount \ of \ Nitrogen}{2} \\\\ Half \ life = \dfrac{120}{2}\\\\\rm Half \ life = 60 \ grams[/tex]

The half-life of the nitrogen after 10 minutes is 60 grams.

The half-life of nitrogen after 20 minutes;

[tex]\rm Half \ life = \dfrac{Amount \ of \ Nitrogen}{2} \\\\ Half \ life = \dfrac{60}{2}\\\\\rm Half \ life = 30 \ grams[/tex]

Hence, after 20 minutes 30 grams amount of radioactive form of nitrogen left.

C, $3,555.63

Step-by-step explanation:

to answer this, we have to use the compound interest formula which is:

A = P(1 + r/n)^nt

the meanings of each variable are:

A = result

P = principal amount

r = rate (in decimal form)

n = the number of compound periods (eg: annually, quarterly, etc)

t = time

in the word problem, we need to solve for A. we are given P, r, n, and t.

P = 2,400

r = 0.0395 also known as 3.95%

n = 4 keyword being quarterly which is equal to the value of 4

t = 10

we can plug these values into the formula:

A = 2400(1 + 0.0395/4)^(4)(10)

we can use a calculator to calculate this easier but ill break it down:

A = 2400(1 + 0.0395/4)^(4)(10)

A = 2400(1 + 0.0395/4)^40

A = 800(1.009875)^40

A = 2400(1.48151088)

A ≈ 3555.626

(b)

g - 3m = am + 5 ( collect the terms in m together )

Add 3m to both sides

g = am + 3m + 5 ( subtract 5 from both sides )

g - 5 = am + 3m ← factor out m from each term

g - 5 = m(a + 3) ← divide both sides by (a + 3)
