Answer:

B

Step-by-step explanation:

if the temp is at 7 then drop seven, the answer is 0

Answer:

Since we have to predict, we can use ratios to help us solve this.

12 said yes out of 72 randomly chosen, SO,

if 210 would say yes (goes to play), how many is total??

12 is to 72 AS 210 is to HOW MUCH (let it be x)??

We can setup ratio, cross multiply, and solve for x:

= 12/72= 210/x

= 12x = 210*72

=12x = 15,120

=x = 15,120/12

Answer:

The answer is B 5.4 units

Step-by-step explanation:

The approximate value of PQ in the right angle triangle is 5.4 units.

A right angle triangle has one of its angles as 90 degrees. Therefore, the sides can be found by trigonometric ratios.

Hence,

sin 50 = opposite / hypotenuse

sin 50 = PQ / 7

cross multiply

PQ = 7 sin 50°

PQ = 7 × 0.76604444311

PQ = 5.36231110183

PQ = 5.4 units

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplify [tex]\sqrt{27}[/tex]

= [tex]\sqrt{9(3)}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex]

= 3[tex]\sqrt{3}[/tex]

Answer:

60.26yd³

Step-by-step explanation:

Since we are not given the diagram, let us assume that;

Length of the base = 5.4yd

Height of the pyramid = 6.2yd

volume of the square pyramid = BH/3

B is the base area = L^2

B = 5.4²

B = 29.16yd²

H = 6.2yd

Get the volume

volume of the square pyramid = 29.16*6.2/3

volume of the square pyramid = 180.792/3

volume of the square pyramid = 60.26yd³

Hence the volume of the square pyramid to nearest hundredth is 60.26yd³

Answer:

4W = 25

Step-by-step explanation:

The hanger is balanced, so each side must have the same quantity.

There are 4W on one side and 25 on the other. That means that 4W and 25 must equal each other in order to keep the hanger balanced.

Answer:

We can see on one side there is 4 w's and on the other side is a 25, because the hanger is balanced these must be equal:

We can form the equation:

4w = 25

w = 6.25

Answer: [tex]170^{\circ}[/tex]

Step-by-step explanation:

Given

The dog has a 25 ft leash

Arc length is 74.3 ft

Arc length is given by

[tex]l=\dfrac{\theta }{360^{\circ}}\times 2\pi r[/tex]

here, r=25 ft

l=74.3 ft

Put the values

[tex]\Rightarrow 74.3=\dfrac{\theta }{360^{\circ}}\times 2\pi \times 25\\\\\Rightarrow \theta =170.2^{\circ} \approx 170^{\circ}[/tex]

The measure of the angle is  [tex]170^{\circ}[/tex]

Answer:

930 is equivalent to 310 because 9 x 10 = 30 x 3 = 90. 1240 is equivalent to 310 because 12 x 10 = 40 x 3 = 120.

Answer:

The decrease is exponential.

Step-by-step explanation:

An exponential decrease is something like:

f(x) = A*(r)^x      with 0 < r < 1

A linear decrease is something like:

g(x) = -a*x + b               with a > 0

First ai general formula.

If you have a quantity Q, decreased by an X%, the new quantity will be:

New Quantity = Q - Q*(X%/100%)

Now let's look at the question:

Suppose that the original price of the computer component is K

And the price as a function of the year is P(y)

Then we know that, in the year zero, the price is K.

P(0) = K

One year after, the price decreases by 2.25%

Then:

P(1) = K - K*(2.25%/100%) = K*(1 - 0.0225)

After another year, we will have another decrease of 2.25%

Then:

P(2) =  K*(1 - 0.0225) -  K*(1 - 0.0225)*(2.25%/100%)

P(2) = K*(1 - 0.0225)*(1 - 0.0225) = K*(1 - 0.0225)^2

We already can see the pattern, we can expect that in the year y, the price of the component will be:

P(y) = K*(1 - 0.0225)^y

This clearly is an exponential decrease.

Answer: x = 13.4

Step-by-step explanation:

1. Subtract 90 degrees and 33 degrees to get angle X, which is 57 degrees.

2. Using Laws of Sine, plug in the known elements of the triangle:

(16) / (sin(90)) = (x) / (sin(57))

3. Cross multiply, this will leave 16sin(57) = xsin(90)

4. Divide sin(90) to the other side, leaving x = (16sin(57)) / (sin(90))

5. Plug this into a calculator and your final answer should be 13.4

Step-by-step explanation:

The value of x in the matrix is 1.

Option D is the correct answer.

Matrix is a form of writing items in rows and columns.

We have,

From the matrix addition, we can write as,

-2x + 3 = x

Now,

Combining the like terms.

-2x - x + 3 = 0

-3x = -3

Dividing 3 into both sides.

-x = -1

x = 1

Thus,

The value of x in the matrix is 1.
