Answer:

30 y

Step-by-step explanation:

We need to multiply 5 by 4y and 5 by 2 y

20y + 10y = 30y

Answer:

30 y

Step-by-step explanation:

You are supposed to distribute(multiply) the 5 with 4y+2y inside the parentheses. Just multiply the 4y by 5 to get 20y and then 2 y with 5 to get 10 y. Your answer should be come out to be 20y + 10y. Since they both use the same variable (y), add them together to get 30y

Answer:

[tex](a)\ (8,-3)[/tex]

Step-by-step explanation:

Given

[tex]y =7x +-59[/tex]

Required

Select all solutions

[tex](a)\ (8,-3)[/tex]

This implies that:

[tex]x = 8; y=-3[/tex]

So:

[tex]y =7x +-59[/tex]

[tex]-3 =7 * 8 + -59[/tex]

[tex]-3 =7 * 8 -59[/tex]

[tex]-3 =56 -59[/tex]

[tex]-3 =-3[/tex]

The above is a solution:

[tex](b)\ (9,8)[/tex]

This implies that:

[tex]x=9\ y =8[/tex]

So:

[tex]y =7x +-59[/tex]

[tex]8 =7 * 9 + -59[/tex]

[tex]8 =7 * 9 -59[/tex]

[tex]8 =63 -59[/tex]

[tex]8 =4[/tex]

The above is not a solution because [tex]8 \ne 4[/tex]

[tex](c)\ (7,-3)[/tex]

This implies that:

[tex]x=7;\ y=-3[/tex]

So:

[tex]y =7x +-59[/tex]

[tex]-3 = 7 * 7 +-59[/tex]

[tex]-3 = 7 * 7 -59[/tex]

[tex]-3 = 49 -59[/tex]

[tex]-3 = -10[/tex]

The above is not a solution because [tex]-3\ne -10[/tex]

[tex](d)\ (10,5)[/tex]

This implies that:

[tex]x =10; y=5[/tex]

So:

[tex]y =7x +-59[/tex]

[tex]5 = 7 * 10 + -59[/tex]

[tex]5 = 7 * 10 -59[/tex]

[tex]5 = 70 -59[/tex]

[tex]5 = 11[/tex]

The above is not a solution because [tex]5 \ne 11[/tex]

Answer:

t=[tex]\sqrt{\frac{38}{g} }[/tex]

Step-by-step explanation:

19=(1/2)gt²

(multiply both sides by 2)

38=gt²

(divide both sides by g)

t²=(38/g)

(square root both sides)

t=[tex]\sqrt{\frac{38}{g} }[/tex]

Answer:

The correct answer is:

(a) 0.0784

(b) 0.0588

(c) 0.1493

Step-by-step explanation:

According to the question,

Number or ace or king,

n (ace or king) = 8

Number of red,

n (red) = 26

Number of club,

n (club) = 13

Number or jack,

n (jack) = 4

(a)

Probability of 1st ace or king and 2nd in red will be:

⇒ [tex]P(ist \ ace \ or \ king \ and \ 2nd \ red) = \frac{8}{52}\times\frac{26}{51}[/tex]

⇒                                                    [tex]=0.0784[/tex]

(b)

Probability of both clubs will be:

⇒ [tex]P(clubs) =\frac{13C_2}{52C_2}[/tex]

⇒                [tex]=0.0588[/tex]

(c)

Probability of at least one is jack will be:

⇒ [tex]P(at \ least \ one \ is \ jack)=1-P(none \ jack)[/tex]

⇒                                       [tex]=1-\frac{48C_2}{52C_2}[/tex]

⇒                                       [tex]=0.1493[/tex]

Number of pounds of a powder that can be stored in the container is 2 pounds.

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Here, a is called the numerator and b is called the denominator.

Given that,

Number of pounds of garlic powder placed in container = 2/3 pound

This is equal to one third of the total space in the container.

So, we can write this as,

Number of pounds of powder in 1/3 space = 2/3 pounds

Number of pounds of powder in 1 full space = 2/3 ÷ 1/3

                                                                          = 2/3 × 3 (by reciprocal rule)

                                                                          = 2 pounds

Hence 2 pounds can be stored in the full container.

Simple interest is an interest added on an amount of money. The yearly interest rate is 1.05%

Simple interest is an interest added on an amount of money. The formula for calculating amount is given as:

Amount. = Principal + Interest

8000 = 1280 + PRT

Substitute

8000 - 1280 = 1280(R)(5)
6720 = 6400R
R = 1.05

Hence the yearly interest rate is 1.05%
