Question 4
Which shows the solution set to the
inequality below?
2x + 35-5

Answer: 7 cm

Step-by-step explanation:

The values of a and b in the sytem of equation are 12 and 9 respectively.

b = 3 / 4 a

a + b = 21

Therefore, let's substitute b in equation(ii)

a + b = 21

a + 3 / 4 a = 21

4a + 3a / 4 = 21

7a / 4 = 21

cross multiply

7a = 21 × 4

7a = 84

divide both sides by 7

a = 84 / 7

a = 12

b = 3 / 4 a

b = 3 / 4 × 12

b = 36 / 4

b = 9

Answer:

If we look at this spinner, we first need to find out how many letters there are in total.

There are 12 letters in total.

1.

For this question, they want us to find the probability of getting the letter 'R'.

We need to find how many letter 'R's there are.

There are 2 lettered 'R', out of the 12 letters.

So the probability of getting the letter 'R' is 2/12 which simplifies to 1/6.

2.

For this question, they want us to find the probability of getting the letter 'L'.

We need to find how many letter 'L's there are.

There are 3 lettered 'L's, out of the 12 letters.

So the probability of selecting the letter 'L' is 3/12 which simplifies to 1/4.

3.

For this question, they want us to find the probability of getting the letter 'B'.

We need to find how many letter 'B's there are.

There are 0 lettered 'B's, out of the 12 letters.

Therefore the probability of selecting the letter 'B' is impossible.

4.

For this question, they want us to find out which letter has the most likely chance of getting landed on.

In order to find this, we need to find one letter that is repeated a lot in this spinner, that way it is more likelier of getting that letter.

Let's look at each individual letter keeping the letters we've found so far to the side.

P(Z) = 4/12, which simplifies to 1/3.

P(S) = 1/12, which is already in simplest form.

P(F) = 2/12, which simplifies to 1/6.

Now let's compare all the probabilities for selecting each letter.

P(R) = 1/6

P(L) = 1/4

P(B) = impossible ← immediately eliminate this choice

P(Z) = 1/3

P(S) = 1/12

P(F) = 1/6

Now out of all of these probabilities, we can infer that the chances of getting the letter 'Z' is the most likeliest.

Answer: b = 4f

Step-by-step explanation:

     Since every flashlight needs 4 batteries, every flashlight added (f) will be 4 more batteries needed total (b). With this information in mind, we can write the equation:

             b = 4f

Answer:

b = 4f

Step-by-step explanation:

4 batteries per flashlight

The percentage of the children that have dog or cat is = 57%

The percentage of children that have a dog = 45%

The percentage of children that have a cat = 30%

The percentage of children that have dog and cat= 18%

Therefore the percentage of children that have dog or cat = (45 + 30) - 18

= 75 - 18

= 57%

Therefore, the percentage of the children that have dog or cat is = 57%

Answer:

Given a triangle ABC, Pythagoras' Theorem shows that:

[tex]c^2=a^2+b^2[/tex]

Thus,

[tex]c = \sqrt{a^2+b^2}[/tex]

The distance formula, gives an equivalent expression based on two points at the end of the hypotenuse for a triangle.

[tex]d^2 = (x_{2} -x_{1})^2 + (y_{2} -y_{1})^2[/tex]

[tex]d = \sqrt{(x_{2}-x_{1})^2 + (y_{2} -y_{1})^2 }[/tex]

Therefore when given the hypotenuse with endpoints at

[tex](x_{1}, y_{1}) and {(x_{2}, y_{2})[/tex]

We know that the third point of the right triangle will be at

[tex](x_{2}, y_{1})[/tex]

and that the two side lengths will be defined by the absolute values of:

[tex](x_{2} - x_{1}) = a[/tex]

[tex](y_{2} - y_{1}) = b[/tex]

Answer:

6 deluxe pizzas

Step-by-step explanation:

200-5=195

195 is the total cost of pizzas

195=11.50x+15.25y

y=−0.75x+12.79

(the y intercept and slope are rounded)

x is reg. pizzas. y is deluxe

x+y=15

y=-x+15

if you plot both y=-x+15 and y=-0.75+12.79 you get coordinates that round to 9,6

9 pizzas

6 deluxe pizzas.

Using the uniform distribution, it is found that there is a 0.9 probability that the tree's angle, from the vertical, will be greater than 4 degrees.

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability of finding a value above x is:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

In this problem, the bounds are a = 3 and b = 13, hence:

[tex]P(X > 4) = \frac{13 - 4}{13 - 3} = 0.9[/tex]

Step-by-step explanation:

Given expression: -k - k

Combine like terms and simplify:

⇒ -k - k

⇒ -(k + k)

⇒ -(2k) = -2k

Determining the constant:

The constant of the term MUST be an integer. It CANNOT be a variable. In this case, the only constant that is a cooeficient of k is -2.

Thus, the cooeficient of -k−k is -2.

Profit is selling price minus cost price, we assumed that the number of candles sold is 100, then the profit is $550

Note: The question is not complete

Given Data

We have the expression

P (x) = 7.5x - 200

Assuming the number of candles sold is x = 100

P (100) = 7.5*100 - 200

P (100) = 750 - 200

Answer:

is this by any chance about simultaneous equations? If so,

Step-by-step explanation:

Step 1 is telling us to decide on whether x and y should be the unknown. For instance, you want x to be the unknown, so u solve for x.

Step 2 is telling us to write equations with x and y.

For example,

7x + 5y = 12

7x - 2y = 9

This may not be accurate but it is an equation.

Step 4 is telling us to check whether the solution is accurate or not. For instance, we say 7 is x. so we substitude 7 into the original equation to see whether the answer we found is correct.

For step 5, im not really sure.

If it didn't have that piece cut out on the bottom, it would be a rectangle that's 9cm wide and 5cm high.  Its area would be 9x5= 45 cm².

But that piece is cut out of the bottom.  The cut-out piece is 3cm wide and 3cm high, so its area is 3x3= 9 cm².

9 cm²  have been cut out of the 45 cm²  of the complete big rectangle.  So the remaining area of the figure is  45 - 9 = 36 cm² .

Answer:

Area of a triangle = (base x height) / 2

if the base is 3 and height is 4

Area = (3x4)/2 = 6 sq units

if the base is 4 and height is 8

Area = (4x8)/2 = 16 sq units

if base is 3 and height is 8

Area = (3x8)/2 = 12 sq units
