14. The ratio between two numbers is 11:9. If the
sum of these two numbers is 40, what is the
product of the numbers?
(a) 396
(c) 400
(b) 432
(d) 384​

Answer:

D; 46 degrees

Step-by-step explanation:

The inscribed angle theorem states that the measure of an inscribed angle is half the measure of its intercepted arc. Arc AC is the intercepted angle of angle ABC. 92/2=46.

Answer:

[tex]\frac{20}{36}[/tex]

Step-by-step explanation:

the total amount of squares within this square is 36

and the number of shaded squares would be 20

so if 20 squares out of 36 squares are shaded, then the fraction is

[tex]\frac{20}{36}[/tex]

or 55.56%

(to find percentage multiply [tex]\frac{20}{36}[/tex] by 100)

Answer:

5/9

= 55.56% ( to the nearest hundredth).

Step-by-step explanation:

The total number of little squares in the large square = 6*6 = 36.

Total number of shaded squares = 2*6 + 2*4

= 12 + 8 = 20.

So the fraction of shaded part

= 20/36

= 5/9.

As a percentage this is 5*100/9

= 55 5/9%

= 55.55..... %

Answer:

equation: x(1.25) + 6.75 = 31.75 refills: 20

Step-by-step explanation:

The mug costs $6.75, and you aren't buying multiple cups, so that number stays the same. The number of refills is "x" since we do not know the amount. Next to "x" we multiply 1.25 for the cost of each refill. So now we have "x(1.25)" then we add $6.75 to the equation, for the mug price. Along with the total at the end. To which we now have "x(1.25) + 6.75 = 31.75"

Now we solve the equation. First, subtract 6.75 from each side

x(1.25) + 6.25 = 31.75

            -6.25    -6.25

Now we have "x(1.25) = 25" So we have to divide each side by 1.25

x(1.25/1.25) = 25/1.25

                x = 20

Therefore, Kim bought 20 refills. To check our work we can replace x with 20 in the original equation.

20(1.25) + 6.75 = 31.75

        25 + 6.75 = 31.75

                31.75 = 31.75

Answer:

The answer is below

Step-by-step explanation:

The equation of a graph of a linear function is in the form:

y = mx + b;

where m is the slope of the graph, b is the y intercept, y and x are the variable.

Since y represent distance on y axis and t represent time on the x axis. We see that the graph passes the points:

(0, 100) and (6, 400). The equation of the graph is:

[tex]y-y_1=\frac{y_2-y_1}{t_2-t_1}(t-t_1) \\\\y-100=\frac{400-100}{6-0}(t-0)\\\\y-100= 50t\\\\y=50t+100[/tex]

a) The y intercept is 0. This means that initially the car is at 100 miles from Phoenix before the trip started. i.e. at 0 hours the distance is 100 miles.

b) The slope of the graph is 50. It means that the car traveled at a speed of 50 miles per hour

c) The end point of the graph is (6, 400), meaning the trip lasted 6 hours

d) The end point of the graph is (6, 400), meaning at the end of the trip, the car was 400 miles from Phoenix.

Answer: Radius 6 because Radius is 1/2 of the diameter so 12/2=6

Diameter 14 because the Radius is 7 so 7x2=14, times 2 because the diameter is 2 radius.

Step-by-step explanation:

The dimensions of the rectangle will be (2x - 9)(x - 5).

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that the area of the rectangle is represented by a quadratic equation 2x² - 19x +45.

The dimensions of the rectangle will be the factors of the quadratic equation.

2x² - 19x + 45

2x² - 10x -9x + 45= 0

2x( x - 5 )-9(x - 5)= 0

( 2x - 9 ) ( x - 5 ) = 0

Therefore, the dimensions of the rectangle will be (2x - 9)(x - 5).

Answer:

[tex](2 \times 8) + ( \frac{1}{2} \times 2 \times 4) \\ = 16 + 4 \\ = 20m {}^{2} [/tex]

Answer with explanation:

From the box and whisker plot of seventh grade we have:

The minimum value =6

First quartile or lower quartile i.e. = 14

Median or second quartile i.e. = 18

Third quartile or upper quartile i.e. =22

and maximum value = 26

From the box and whisker plot of eighth grade we have:

The minimum value =22

First quartile or lower quartile i.e. = 26

Median or second quartile i.e. = 30

Third quartile or upper quartile i.e. = 34

and maximum value = 38

a)

The overlap of the two sets of data is as follows.

   The upper quartile or third quartile of seventh grade is same as the minimum value of the data of eighth grade.

   And the maximum value of seventh grade is same as the lower quartile of eighth grade.

b)

IQR is calculated as the difference of the Upper quartile and the lower quartile

i.e.

so, IQR of seventh grade is:

22-14=8

IQR of seventh grade=8

IQR of eighth grade is:

34-26=8

Hence, IQR of eighth grade=8

c)

The difference of the median of the two data sets is:

30-18=12

Hence, the difference of median is: 12

d)

As the IQR of both the sets is same i.e. 8.

Hence, the number that must be multiplied by IQR so that it is equal to the difference between the medians of the two sets is:

Hence, the number is : 1.5

Answer:

2.5 cm

Step-by-step explanation:

let y represent the unknown distance

4 cm = 60 miles

y cm = 37.5 miles

we then cross multiply

4 × 37.5 = 60 x y

150 = 60 y

divide both side by 60

150/60 = 60y/60

y = 2.5cm
