A spinner has 6 equally divided sections labeled A, B, C, D, E and F. After spinning the spinner, a number cube is rolled. What

bagirrra123 [75]

Answer: $\dfrac{2}{9}$

Step-by-step explanation:

Given

The spinner has 6 equal sections A, B, C, D, E, and F

The two events occurred one after the other. So, the probability is the product of the probabilities of each event.

There are two consonants in the given 6 letter

The probability of landing over a consonant is

$P_1=\dfrac{2}{6}$

The number greater than 2 in a cube are 3,4,5,6

So, probability corresponding to it

$P_2=\dfrac{4}{6}$

So, the required probability is

$\Rightarrow P=P_1\times P_2\\\Rightarrow P=\dfrac{2}{6}\times \dfrac{4}{6}\\\\\Rightarrow P=\dfrac{8}{36}\\\\\Rightarrow P=\dfrac{2}{9}$

-2x - 6y = -24<br> X-8y = -10

Debora [2.8K]

Answer:

x = -26 and y = -2

I hope this is the answer you are looking for

Step-by-step explanation:

x-8y = -10 => add 8y to both sides

+8y = +8y

x = -10+8y

-2(-10+8y) -6y = -24 => intersect what you got into the first equation

20-16y-6y = -24 => Distribute the -2

20-22y = -24 => subtract 20 in both sides

-20 = -20

-22y = -44 => divided by -22 in both sides

/-22 = /-22

y = -2

x-8(-2) =-10 => intersect the y into the other equation

x+16 = -10 => multiply -8*-2

-16 = -16

x = -26 => subtract 16 in both sides.

For which expression is the sum of the constants greater than the sum of the coefficients?

Svetach [21]

Answer:

$8+3x^2+7x+4$

Step-by-step explanation:

The first expression is

$7+3x^2+7x+3$

The sum of the constants is 7+3=10

The sum of the coefficients is 3+7=10

The second expression is;

$7+4x^2+4x+1$

The sum of the constants is 7+1=8

The sum of the coefficients is 4+4=8

The third expression is;

$8+4x^2+8x+2$

The sum of the constants is 8+2=10

The sum of the coefficients is 4+8=12

The fourth expression is;

$8+3x^2+7x+4$

The sum of the constants is 8+4=12

The sum of the coefficients is 3+7=10

Hence the correct choice is the expression in which the sum of the constants greater than the sum of the coefficients

A carpet costs $15 per square foot. (when calculating the price any fraction of a square foot is counted as a whole square foot)

olga2289 [7]

Wow ! That is some expensive carpet !

If (1 meter) = (3.28 feet), then (1 meter)² = (3.28 feet)² = about 10.76 square feet

19.7 square meters = (19.7 x 10.76) = 211.972 square feet. Call it 212 .

(212 square feet) x ($15 / sq ft) = <em>$3,180</em> .
