Answer:

A, B, D, E

Step-by-step explanation:

To find if something is equal to fifty percent, split the second number in half.

For example, lets use option D.

32/2=16

16 is the first number in the option, meaning it is 50%.

Lets use an example where it wouldn't work. In this case, option C.

12/2=6

6≠9

Meaning 9 is not 50% of 12.

Answer:

Number of planes needed = total number of people ÷ number of people 1 plane can hold

⇒ number of planes needed = 49 ÷ 6 = 8 1/6 = 8 remainder 1

Therefore, 9 planes will be needed to transport 49 people.

8 planes will be full and 1 plane will not be full.

There will be 1 person in the plane that is not full.

Answer:

26 y + 5

Step-by-step explanation:

Simplify the following:

7 3 y + 4 3 y - 3 y - 2 2 y + 5

7×3 = 21:

21 y + 4 3 y - 3 y - 2 2 y + 5

-2×2 = -4:

21 y + 4 3 y - 3 y + -4 y + 5

4×3 = 12:

21 y + 12 y - 3 y - 4 y + 5

Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:

(21 y - 4 y + 12 y - 3 y) + 5

21 y - 4 y + 12 y - 3 y = 26 y:

Answer: 26 y + 5

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:

Step-by-step explanation:

small=s,    s=3.99

large=l,       l=19.20

10s+8l=192.20

20s+l=99

we can see that in the second equation, 20s+l=99

l=99-20s

lets replace l in the first equation

10s+8(99-20s)=192.20

10s+792-160s=192.20

-150s=-792+192.20

150s=599.80

s=3.99

l=99-20(3.99)=99-79.80=19.20

Answer:

19

Step-by-step explanation:

You can set up a system of equations.

x=small, and y = large.

10x+8y=$192

20x+1y=$99

you can multiply the first equation by -2 to get rid of x:

20x+1y=$99

-20x-16y=-$384

when you combine them, you get:

-15y=$-285

you can divide by -15 and you get:

y=19, so 1 large equals $19

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

[tex]\rule[225]{225}{2}[/tex]

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.

-15a² -14a+16

Step-by-step explanation:

2×8=16

2×5a=10a

-3a×8=-24a

-3a×5a=-15a²

16+10a-24a-15a² = -15a² -14a+16

Step-by-step explanation:

use this equation

y = mx + c

m is the gradient

c is the y intercept

m is

m is rise/run

the line rises from 3 to 10

so rise is 7

the line runs from 0 to 3.5

so run is 3.5

m = 7/3.5

m = 2

c is

y-intercept is where the line is equal to x=0

that point is

(0, 3)

so y int is 3

c = 3

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.

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
