Answer:

The coefficients are b and a

The coefficients in the expression are 3 and 7.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given expression is,

9 - 4 + 3b + 7a

So, from the given expression we can see that there are 4 terms, 2 constants and 2 coefficients.

The coefficient of b is 3,

and coefficient of a is 7.

So, there are 2 coefficients in the given expression.

Thus, the coefficients in the expression are 3 and 7.

Answer:

-4

Step-by-step explanation:

-1.5 (4-r) = -12   Distribute the -1.5.  

-6 - 1.5r = -12   Add 6 to both sides.

-1.5r = 6  Divide both sides by -1.5.

Step-by-step explanation:

The solution means that Riko will be behind Yuto from the time she leaves the house, which corresponds to t = 0, until the time she catches up to Yuko after 52.5 minutes, which corresponds to t = 52.5. The reason that t cannot be less than zero is because it represents time, and time cannot be negative.

Answer:

-4sinθcosθ

Step-by-step explanation:

Note:

1. (a + b)^2 = a^2 + 2ab + b^2

2. (a - b)^2 = a^2 - 2ab + b^2

3. sin^2θ + cos^2θ = 1

(sinθ -cosθ)^2 - (sinθ + cosθ)^2

= sin^2θ - 2sinθcosθ + cos^2θ - (sin^2θ + 2sinθcosθ + cos^2θ)

= sin^2θ + cos^2θ - 2sinθcosθ - (sin^2θ + cos^2θ + 2sinθcosθ)

= 1 - 2sinθcosθ - (1 + 2sinθcosθ)

= 1- 2sinθcosθ -1 - 2sinθcosθ

= - 2sinθcosθ - 2sinθcosθ

= -4sinθcosθ

Answer: 64

Step-by-step explanation:

From the question, we are informed that Lisa is currently taking physics as one of her electives in school and that her grade at the end of the year is determined by the average of four exams, each worth 100 points.

First test = 84,

Second test = 92

Third test = 80

Forth test = y

The fourth test is denoted by y.

Since we are told that she must get exactly 80% in the course and she took 4 exams, that means her total score will be: = 80 × 4 = 320

Therefore,

84 + 92 + 80 + y = 320

256 + y = 320

y = 320 - 256

y = 64

The fourth exam's score is 64

Answer:

25%

Step-by-step explanation:

You set up the proportion 108.75/145 is x/100 to find out what percentage of 145 108.75 is. You can then use this proportion to find that percentage with cross multiplying, by doing this you get the equation 108.75 times 100 is equal to 145x. Then you simplify to get 10,875=145x. Then you solve like regular by dividing both sides by 145 to get x=75. Now we know that 108.75 is 75% of 145, but we aren't done yet. Now in order to find the discount price you subtract 75 from 100 to get 25, so you're finding the difference between 100 and the x-value we just found. The final answer is 25%

Answer:

C = 600 + 50s

Step-by-step explanation:

The students are planning to visits the Canada's wonderland. The students will spend a full day at the park.

The entry fee for each student is $50 and the bus cost is $600. Each student will pay $50 for entry into the park.

Let

the number of student  = s

cost of the trip = C

Relating the variable C and s

The total amount of money the student will pay for entry fee = 50 × s = 50s

Therefore, cost of the trip can be expressed as follows

C = 600 + 50s

Answer:

15d + 50 = 125

15d = 75

5 days

Step-by-step explanation:

Her total must equal $125.

She has $50 so far.

50 + _____ = 125

In the blank, we will put what she will earn by walking the dogs.

Each day she will earn $15. In d number of days, she will earn 15d.

The equation is:

50 + 15d = 125

15d + 50 = 125

We can subtract 50 from both sides to get

15d = 75

Now we solve the equation to find the number of days.

We divide both sides by 15.

15d/15 = 75/15

d = 5

She will need to walk the dogs for 5 days.

B, A, C are the answers

Answer:

54.6 cm : B

Step-by-step explanation:

Mathematically the area of a rectangle is 2( l + b)

So in practical terms we only need the measure of two sides as we have 2 equal sides for a rectangle.

We can see that we have two right angles on each sides

Now to find b, we can use trigonometric ratios

For each of the rectangles, the diagonal represents the hypotenuse

Mathematically;

sin 30 = b/20

From triangle ABC

b = 20 sin 30 = 20 * 0.5 = 10 cm

Now, to get l

Mathematically;

Sin 60 = l/20

l = 20 sin 60 = 17.32 cm

So the perimeter is;

2(10 + 17.32)

2(27.32) = 54.64 cm which is 54.6 to the nearest tenth

Answer: C

Step-by-step explanation:

G(x)= 1/4 x²

A fraction causes the parabola to become wider

Function [tex]f(x) = x^{2}[/tex] represents the graph of parabola while  [tex]g(x) = \frac{f(x)}{4}[/tex] represents the horizontally stretched  form of f(x). Parabola become wider.

" Graph is defined as the representation of the relation between two variable on the coordinate plane along x-axis and y-axis."

According to the question,

Given function

[tex]f(x) = x^{2}[/tex]

g(x) is defined as divide f(x) by 4.

[tex]g(x) = \frac{f(x)}{4}[/tex]

       [tex]= \frac{x^{2} }{4}[/tex]

Graph becomes wider as shown in the graph drawn with comparison of f(x) and g(x),

Hence, Option(C) is the correct answer.

The value obtained after dividing x³+48x-64-12x² by x²+16-8x will be (x-4).

The number being divided is referred to as the dividend, and the number being divided by it is referred to as the divisor. The quotient is the outcome of the division.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

It is given that,

= ( x³+48x-64-12x²)  / (x²+16-8x)

Using the identity (a-b)² = a²+b²-2ab as,

⇒(x²+16-8x) = (x-4)²

= ( x³+48x-64-12x²)  / (x-4)²

Using the identity (a-b)³ = a³ -3a²b +3a²b -b³

⇒ ( x³+48x-64-12x²) = (x-4)³

Substitute the value as

=(x-4)³ / (x-4)²

=(x-4)

Thus, the value obtained after dividing x³+48x-64-12x² by x²+16-8x will be (x-4).

Answer:

The difference in the water potential ∆P is 7 bar.

∆P = 7 bar

Step-by-step explanation:

Given;

The water potential in one plant cell was calculated to be -4 bar

P1 = -4 bar

The water potential in another cell was found to be -11 bar.

P2 = -11 bar

The difference in the water potential ∆P is;

∆P = P1 - P2

Substituting the given values;

∆P = -4 - (-11) bar

∆P = -4 +11 bar

∆P = 7 bar

The median is the line cutting the triangle in this graph. In general, a median connects any of the triangle points to halfway across the side opposite to that point. This median connects R to halfway across the side across from R.

We want to find the equation of  this median. We see that T is at (-2,3) and R is (3,-3). The first thing to do when looking for the equation of the line is to find the slope, or incline. Since we have two points, we can do this very easily. You simply divide the difference in the y-values by the difference in the x-values.

DIFFERENCE IN Y-VALUES

3-(-3)

3+3

6

DIFFERENCE IN X-VALUES

-2-3

-5

Now, we divide the two answers, giving us -6/5.

So, we have our slope, which gives us the equation so far y=-6/5x+b. We just need to find the b, which is our y-intercept. Well, to do this, we plug in one of our points and we can solve for b. We will use (3,-3)!

-3=-6/5(3)+b

-3=-3 3/5+b

We add 3 3/5 to both sides to isolate the b.

b=3/5

This means that this median should hit the y-axis at (0,3/5), and it looks like it does. Therefore, the equation of this median is y=-6/5x+3/5.

Now you can find the slope of a median! Have a wonderful day! :D

Answer:  Use a tree diagram for conditional probability

The first branch lists the elements in the starting field-- how many items or outcomes. Like heads or tails, how many of each color of marbles or socks, etc. The next branch shows the set of outcomes from the first event and what is available for the next event. The branches are labeled with fractions to tell the chances of each outcome.

Step-by-step explanation:

A tree diagram is good for determining probability when there are multiple steps in the "draw" and multiple outcomes-- sometimes chances of event a and b "this and that" or event a or b "this or that"

You use the fractions on each branch to calculate the final outcome. If it's a and b, you multiply the fractions on each "trail" you follow through the branches to get the defined final outcome.

If it is a or b, you add the fractions to get the probability of the defined final outcome.

Answer:

n = 7

Step-by-step explanation:

The sum of the interior angles of a polygon is 9[tex]x^2[/tex]. If x is 3 greater than the number of sides of the polygon, how many sides does the polygon have?

The sum of the interior angles of a concave polygon can be found using the formula S = (n - 2)*180.

n= number of sides of the polygon

n-2 * 180 = the sum of the interior angles

9[tex]x^2[/tex]= the sum of the interior angles

9[tex]x^2[/tex]= (n-2) *180

x= 3+ n

9 [tex](3+n)^{2}[/tex]=(n-2) *180

9 (9+6n+n^2) = (n-2) *180

81+54n+9n^2 = (n-2) *180

n = 7
