Answer:

56 pack

Step-by-step explanation:

To find the number of packs of seed needed, we will first find the area of the rectangular backyard. We're given that the length is 32 feet and the width is 21 feet.

We get the following. Area =length × width =×3221 =672 square feet So the area of the backyard is 672 square feet. Each pack of seed covers 12 square feet. So we can find the number of packs of seed needed as follows. =÷6721256 packs Thus, Justin will need 56 packs of seed.

Answer:

1.20x + 2.5 ≤ 20

Step-by-step explanation:

This would be the best inequality to use.

How much Cups She Can Buy

x is the ammount of cups so we will solve for x

Subtract 2.5 from both sides

1.20x + 2.5 -2.5 ≤ 20 - 2.5.

1.20x ≤ 17.5

Divide both sides by 1.20

1.20x/1.20 ≤ 17.5/1.20

x ≤ 14.5833...

She can buy 14 cups

Step-by-step explanation:

Step 1:  Make an equation

20 ≥ 2.50 + 1.20x ← Best inequality

Step 2:  Subtract 2.50 from both sides

20 - 2.50 ≥ 2.50 - 2.50 + 1.20x

17.5 ≥ 1.20x

Step 3:  Divide both sides by 1.20

17.5 / 1.20 ≥ 1.20x / 1.20

14.583... ≥ x

====================================================

Work Shown:

5% = 5/100 = 0.05

5% of 42 = 0.05*42 = 2.10

tax = $2.10

total cost including tax = $42 + $2.10 = $44.10

----------

An alternative is to multiply 42 by 1.05 to get

1.05*42 = 44.10

We get the same answer. The 1.05 refers to 1 + 0.05 where the "1" is 100% and the 0.05 is 5%, so the two combine to 105%, meaning the total cost is 105% of the cost before tax is considered.

Answer:

1500p

Step-by-step explanation:

The spinner A has 4 possible values, and the spinner B has 3 possible values, so the total number of possibilities for both spinners is the product of these number of possibilities:

4 * 3 = 12

From these 12 possible pair of values, the ones that give a sum of 7 are:

(6,1), (4,3) and (2,5).

We have 3 cases where the sum is 7, so the probability of having a sum of 7 is 3/12 = 25%. Therefore, the probability of not having a sum of 7 is 75%

To find the expected value, we multiply the probability of each case by the value it would give. If the player wins, the school loses 10p (the player paid 20p and earned 30p), and if the player loses, the school wins 20p. So the expected value of 120 games is:

120 * (0.25 * (-10) + 0.75 * (20)) = 1500p

Answer:

$345 : whichever is closest

Step-by-step explanation:

Pants were $20 each and she bought 9 of them so multiply:

9x20=180

She paid $180 for 9 pants.

Shirts cost $15 each and she bought 11 of them so Mulitply:

15x11=165

She paid $165 for 11 shirts

Add both totals from pants and shirts

165+180=$345

Answer: 350

Step-by-step explanation: I dont really now how but 345 is close to 350 and my learning app says so.I'M really bad at math but if get this questoin an Modymax than the awsnser is 350.

Answer:

The required probability is option [tex]C)\ \dfrac{1}{9}[/tex]

Step-by-step explanation:

There are a total of 9 cards.

Total number of cases = 9

Let A be the event of choosing 1, 2 or 3.

Total number of favorable cases for event A = 3

Let B be the event of choosing 7, 8 or 9.

Total number of favorable cases for event B = 3

Formula for finding probability of an event E is:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Finding P(A), using the formula:

[tex]P(A) = \dfrac{3}{9}\\\Rightarrow \dfrac{1}{3}[/tex]

Now, it is given that the card is replaced, so again total number of cases are 9.

For finding P(B), using the formula:

[tex]P(B) = \dfrac{3}{9}\\\Rightarrow \dfrac{1}{3}[/tex]

To find the probability that events A and B both happen, we can simply multiply P(A) and P(B) because these are independent events.

[tex]\text{Required probability = }P(A) \times P(B)\\\Rightarrow \dfrac{1}{3} \times \dfrac{1}{3} \\\dfrac{1}{9}[/tex]

Answer:

d. g36

Step-by-step explanation:

The solution is, g^36 power is equivalent to the expression (g-12)-3.

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

here, we have,

given expression is,

g^(-12)(-3)

=g^(12*3)

=g^36

Hence, The solution is, g^36 power is equivalent to the expression (g-12)-3.

The values for a and b in the given exponential function are a = 4 and b = 1/2

An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.

For example, exponential functions can be used to calculate changes in population, loan interest charges, bacterial growth, radioactive decay or the spread of disease.

Given that,

The exponential function is given as, y = abˣ, we need to find the value of a and b,

When x = 0, ab⁰ = 4

a=4 (since, b⁰ = 1)

When x = 1, ab¹ = 2

4b = 2

b = 1/2

Hence, The values of a and b are a = 4 and b = 1/2

Answer:

This is a right triangle

Step-by-step explanation:

We can check if this is a right triangle by using the Pythagorean theorem

a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse

3^2+4^2 = 5^2

9+16 = 25

25=25

This is true so it is a right triangle

Answer:

x= 100º

y= 260º

Step-by-step explanation:

x= 180º-42º-38º

x= 100º

y= 360º-100º

y=260º

Answer:

x =80°

y = 280°

Step-by-step explanation:

Given: [tex] AB \parallel CD[/tex]

Extend segment CE in the direction of E in such a way that it intersects ray AB at point say P.

[tex]\therefore m\angle APE = m\angle ECD..(Alternate\: \angle s)\\

\because m\angle ECD = 42°\\

\therefore m\angle APE = 42°\\[/tex]

So, x° would be the exterior angle of [tex] \triangle AEP.[/tex]

Hence, by remote interior angle theorem of a triangle, we have:

[tex]x = 38° + 42°\\

\huge\purple{\boxed{x = 80° }}\\\\

y = 360\degree - 80\degree\\

\huge\red{\boxed{y= 280\degree}}[/tex]

Answer:

For y=x-3. (0,2) the equation is y=x+2

For y=3-x. (0,2) the equation is y=2-x

For y=3x+1. (0,3) the equation is y=3x+3

For y=-1/2x+4. (0,1) the equation is y=-1/2x+1

Step-by-step explanation:

How I got my answers:

For y=x-3: the gradient is 1 because we do not have anything before x.

For the points given for example (0,2) x is zero  and y-intercept is 2. same for the rest of the points.

Now you can write your equation in the form y=mx+b

where m is your gradient, and b is the y point. So you say y=1x+2 for the first one. Do the same for the rest. Remember 1x is the same as x so you can leave out 1.

Answer:18

Step-by-step explanation:

Answer:

BC = 15

Step-by-step explanation:

Because of parallel lines, AD and BE, triangles ADC and BEC are similar.

In similar triangles, the lengths of corresponding sides are proportional.

AC/BC = DC/EC

We see that AC = AB + BC = 3 + BC

Also, DC = DE + EC = 2 + 10 = 12

(3 + BC)/BC = 12/10

(3 + BC)/BC = 6/5

Cross multiply.

5(3 + BC) = 6BC

15 + 5BC = 6BC

15 = BC

BC = 15

Answer:

The first step is to expand it to get rid of brackets .

Step-by-step explanation:

The first step, you have to eliminate brackets by expanding :

[tex]2(3k + 1) = 4k + 32[/tex]

[tex]2(3k) + 2(1) = 4k + 32[/tex]

[tex]6k + 2 = 4k + 32[/tex]

Next you have to collect like terms by making the same variable to one side and lastly, solve it :

[tex]6k - 4k = 32 - 2[/tex]

[tex]2k = 30[/tex]

[tex]k = 30 \div 2[/tex]

[tex]k = 15[/tex]

Answer:

Use the distributive Law on the left side of the equation.

Step-by-step explanation:

The first step is to distribute the 2 over the parentheses:

2(3k + 1) = 4k + 32 Distributing:

2*3k + 2*1  = 4k + 3

6k + 2 = 4k + 3

2k = 1

k = 1/2.

Answer:

The value of x is 12

Step-by-step explanation:

4x3=12

7x3=21

Therefore 12/21

To explain further:

If you divide 12 by 3 you get 4

If you divide 21 by 3 you get 7

Therefore resulting to 4/7
