Step-by-step explanation:

30x30 is 900

x+y=40

15x+8y=400

Step-by-step explanation:

x= Adults

y= Children

$15 dollars per "X" adults + $8 dollars per "Y" children = 400 dollars, and "X" adults + "Y" children = 40 people on the bus.

We are told that c(16x + 14) = 32x + d

Now, if  16x + 4 is multiplied by 2 we will have:

2(16x+14)=32x+28

then 32x + 28 = 32x + d

Since C(16x+14) = 32x+d

and 2 (16x+14) = 32x + d

then c = 2, d = 28

Answer:

[tex]\huge\boxed{\sf r = 37\ mm}[/tex]

Step-by-step explanation:

Let the radius be r

UV is tangent to the circle T which means UV is perpendicular to UT, that makes ΔUVT a right-angled triangle.

Which means:

∠TUV = 90°

So, We can use pythagoras theorem to find the radius of the circle.

In the Δ:

Hypotenuse = r + 9

Base = r

Perpendicular = 12

Pythagoras Theorem:

(Hypotenuse)² = (Base)² + (Perpendicular)²

(6 + r)² = (r)² + (22)²

(6)² + 2(6)(r) + (r)² = r² + 484

36 + 12r + r² = r² + 484

Subtract r² to both sides

36 + 12r = 484

Subtract 36 to both sides

12r = 484 - 36

12r = 448

Divide both sides by 12

r = 448/12

r = 37 mm

The Linear Regression Equation has the form Y= a + bX. The reasonable prediction for the number of t-shirts sold is 18.

The Linear Regression Equation has the form Y= a + bX, where Y is the dependent variable (that's the variable that goes on the Y-axis), X is the independent variable (i.e. it is plotted on the X-axis), b is the slope of the line and a is the y-intercept.

In order to calculate the reasonable prediction for the number of t-shirts sold, we need to find the function of the given graph below.

As we can see that the function of the graph is linear(line), therefore, we take two points, to find the value of the slope and the value of the constant.

[tex](x_1,y_1)=(10,25)\\(x_2,y_2)=(15,12)[/tex]

The value of the slope can be written as,

[tex]m=\dfrac{y_2-y_1}{x_2-x_1} = \dfrac{12-25}{15-10}=\dfrac{-13}{5}[/tex]

Now, substitute the value of any one point in the equation of the line,

[tex]y=mx+c\\\\y_1=\dfrac{-13}{5}x_1+c\\\\25=(\dfrac{-13}{5}\times 10)+c\\\\25=-26+c\\\\51=c[/tex]

As the price of the t-shirt is $13, therefore, the value of y(or the reasonable prediction for the number of t-shirts sold) can be found,

[tex]y=\dfrac{-13}{5}x+51\\\\y =(-2.6 \times 13)+51\\\\y = 17.2[/tex]

The value of the reasonable prediction for the number of t-shirts sold is 17.2 which is close to 18.

Hence, the reasonable prediction for the number of t-shirts sold is 18.

Solving the linear equation 12.5 = -1.5 + b/0.1, value of b is 1.4

Linear equation is an equation containing one unknown variable with power one and constants.

The standard form of an linear equation in one variable x is :

ax + b = 0 , where a, b are constants

x= -b/ a is solution of this equation or we can solve this equation by adding or subtracting same number to both sides.

To solve  equation : 12.5 = -1.5 + b/0.1

Adding 1.5 to both sides

12.5 +1.5 = -1.5 +1.5 + b/0.1

14 = b/0.1

Multiply both sides by 0.1

0.1 *14 = 0.1(b/0.1)

1.4 = b

Therefore, the value of b on solving linear equation 12.5 = -1.5 + b/0.1 is 1.4

The system of equation is solved and the x-intercept is (15, 0) and y-intercept is (0, 5)

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To graph the equation 2x + 6y = 30, we need to rewrite it in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept

2x + 6y = 30

6y = -2x + 30

y = (-2/6)x + 5

y = (-1/3)x + 5

To interpret the intercepts, we look at the x-intercept and y-intercept of the graph

X-intercept: To find the x-intercept, we set y = 0 and solve for x

y = (-1/3)x + 5

0 = (-1/3)x + 5

(-1/3)x = -5

x = (-5) / (-1/3)

x = 15

The x-intercept is (15, 0), which means that when y = 0, we can buy 15 bottles of paint and no tubs of clay with the available $30

Y-intercept: To find the y-intercept, we set x = 0 and solve for y.

y = (-1/3)x + 5

y = (-1/3)(0) + 5

y = 5

The y-intercept is (0, 5), which means that when x = 0, we can buy no bottles of paint and 5 tubs of clay with the available $30

Hence , if 3 tubs of clay are purchased, we can buy 6 bottles of paint

Answer:

28 cm per year

5.5 years

Step-by-step explanation:

In three years time, the height of the tree grew from 190 to 274, that's an increase of 84 cm. Divice that by the number of years it took. So you get this calculation:

(274-190)/3 = 28

When the tree was 344 centimeters tall, the increase was 344-190 = 154. Divide that by the 28 found earlier to get 154/28 = 5.5 years.

Answer:

B. 204 pens

Step-by-step explanation:

If you have 10 boxes of 30 pens each, the problem would be like so:

10 x 30 = 300

Now, since we have 32 workers that each take 3, this turns into:

32 x 3 = 96

Finally, because 300 is the total amount of pens and 96 is the amount taken, we just subtract to get:

300 - 96 = 204 pens

Using the "Pythagorean Theorem" formula:

a^2 + b^2 = c^2 we can find the hypotenuse of this triangle.

Replace the values of a, b, and c with it's actual values;

8^2 + 4^2 = __^2 ← our missing value

64 + 16 = 80, now we need to find the square root of 80:

√80 = 8.944, which equals to around 8.9.

so to rewrite:

8^2 + 4^2 = 8.9^2, so 8.9 is your answer.

The triangle

The height is calculated using the Pythagoras theorem as

h²= 60² - 36²

So, we have

h²= 2304

Evaluate

h = 48

Next, we have

(x -36) * 36 = 48 * 48

When evaluated, we have

x -36 = 64

So, we have

x = 64 + 36

Evaluate

x = 100

Hence, the value of x is 100
