Step-by-step explanation:

12 - 1 = 11

to solve for q all you had to do was 12-11=1 (switch 11 and one)

Hey there!

11 = 12 - q

-q + 12 = 11

SUBTRACT 12 to BOTH SIDES

-q + 12 - 12 = 11 - 12

SIMPLIFY IT!
-q = 11 - 12

-q = -1

-1q = -1

DIVIDE -1 to BOTH SIDES

-1q/-1 = -1/-1

SIMPLIFY IT!

q = -1/-1

q = 1

Therefore, your answer should be:

q = 1

Good luck on your assignment & enjoy your day!

  • In Mathematics, rectangle and square are both four sided polygon, having all the internal angles equal to 90.The opposite sides of the rectangle are equal in length whereas in square all the sides are same which makes rectangle different from square.

  • Area of rectangle is the product of length and breadth of rectangle. Perimeter of rectangle is twice the sum of its length and breadth. Area of square is side * side and perimeter of square is 4* side.

  • Area of rectangle = l*b

Perimeter of rectangle = 2(l+b)

  • Area of square = side * side

Perimeter of square  = 4 * side

We are given that perimeter of square and rectangle is same and the side of square is 4x-1 and length of rectangle is 2x+2 and width of rectangle is 2x.

Perimeter of Square = Perimeter of rectangle

4 * (4x-1) = 2(4x+2)

16x -4 = 8x + 4

8x = 8

x = 1

The value of x is 1

Side of square = 4 – 1 = 3

Length of rectangle = 4

Breadth of rectangle = 2

The value of the fourth term in a geometric sequence is 3/8.

We are meant to find the value of the fourth term in a geometric sequence for which a1 = 3- and r = 1/2.

It should be noted that the formula will be:

ar^n-1

where n = 4

r = 1/2

a = 3

Therefore, ar^n-1 = ar^(4-1) = ar³

= ar³.

= 3(1/2)³

= 3 × 1/8

= 3/8

Thw 4th term is 3/8.

Answer:

y = [tex]\frac{2}{5}[/tex] x + 2

Step-by-step explanation:

Graph below.

Answer:

y = 2/5x + 2

Step-by-step explanation:

y = mx + b

First, we find out the slope. The slope is the change in y over the change in x.

The change in y is the second y-value subtracted from the first. The first y-value is 0 and the second is 2.

0 - 2 = -2

The change in x is the second x-value subtracted from the first. The first x-value is -5 and the second is 0.

-5 - 0 = -5

The slope is the change in y over the change in x.

-2/-5 = 2/5

y = 2/5x + b

b is the y-intercept, which is the value of y when x = 0.

When x = 0, y = 2 (0,2), so b = 2.

y = 2/5x + 2

Gina—her standardized score is higher than Colleen’s. The person who did better relative to their peers is Gina and this is because her standardized score is higher than Colleen

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

For Gina

Gina took the SAT in 1994 and scored 500 on the Math test.

For Math scores, the mean under the old scale in the 1990s was 470 and the standard deviation was 110.

x = 500

μ = 470

σ = 110

Hence, the z score is given as:

z = 500 - 470/110

z = 0.27273

Gina's z or standardized score is 0.27273

For Colleen

Her cousin Colleen took the SAT in 2016 and scored 530 on the Math test.

In 2016 the mean was 510 and the standard deviation was 103.

x = 530

μ = 510

σ = 103

Hence, the z score is given as:

z = 530 - 510/103

z = 0.19417

Colleen's z or standardized score is 0.19147

Answer:

  22/44

Step-by-step explanation:

The probability of black is the ratio of black cards to all cards. If the Ace and 2 are removed from each suit, there will be 11 of the 13 cards remaining. 2 suits are black, for a total of 2×11 = 22 black cards. Of course there are 4 suits altogether, for a total of 4×11 = 44 total cards. Then you have ...

  P(black) = (black cards)/(total cards)

  P(black) = 22/44

_____

You are expected to be familiar with the fact that a deck of 52 playing cards consists of 4 suits: diamonds, clubs, hearts, spades. Each suit has 13 cards, identified as Ace, 2, 3, ..., 10, Jack, Queen, King. The clubs and spades are black; the diamonds and hearts are red.

The random variable r has a mean μ = 10 and σ = 4. For the variable s, the μ = 7 and σ = 3. The mean of r-s will be obtained by arithmetic subtraction of the μ for r and a. The standard deviation isn't independent since it's obtained by square root of the variance of a distribution. The standard deviation will be obtained by obtained through the square root of the squared sum of σ.

μ (r-s) = μ(r) -μ(s)

μ (r-s) = 10 -7 = 3

σ (r) -σ(s) = √(σ (r))²+ (σ (s))²

σ (r) -σ(s) = √(4²+ 3²)

σ (r) -σ(s) = √(16+ 9)

σ (r) -σ(s) = √25 = 5

thus, the mean is 3 and the standard deviation is 5.

Answer:

Because AC = BC

=> ️ACB is a isosceles triangle at C

=> m<A = m<B = 71°

At triangle ABC

m<A + m<B + m<ACB = 180°

=> 71° + 71° + m<ACB = 180°

=> m<ACB = 38°

We have m<ACB and m<ECD are 2 opposite angle

=> m<ECD = m<ACB = 38°

At triangle ECD

m<ECD + m<E + m<D = 180°

=> 38° + 90° + m<D = 180°

=> m<D = 52°

The toy rocket will take a time of 6.8571 seconds to hit the ground.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given that the height of the rocket (h), in meters, in terms of time (t), in seconds, is defined by a quadratic equation.

To determine the time needed for the rocket to hit the ground, that is, a time t greater than zero such that the height is zero. Now we proceed to solve the polynomial:

- 4.9 · t² + 33.6 · t + 4.9= 0

- 4.9 · (t² - 6.8571 · t - 1) = 0

- 4.9 · (t - 6.8571 ) · (t + 6.8571 ) = 0

Hence, the toy rocket will take a time of 6.8571 seconds to hit the ground.

Answer:

280 ml as a percentage of 140 l is 0.2%

Step-by-step explanation:

∵ There is an amount of 280 ml

∵ The total amount is 140 l

→ Change the liter to milliliters using the 1st point above

∴ 140 l = 140 × 1000 = 140000 ml

∴ 140 l = 140,000 ml

→ Now divide the amount by the total, then multiply the quotient by 100%

∵ 280 ÷ 140,000 = [tex]\frac{1}{500}[/tex]

∵ [tex]\frac{1}{500}[/tex] × 100% = 0.2%

∴ 280 ml as a percentage of 140 l is 0.2%

Answer: 26

Step-by-step explanation:

Okay, so... The new equation would be -2(-3)+20...

So follow the rule of PEMDAS, PEMDAS is;

Parentheses

Exponents

Multiplication

Division

Adding

and Subtracting

Since there are no equations in parentheses and no exponents, we start with multiplication. Which would be -2(-3). ANY parenthesized number beside another number means you must multiply them.

-2(-3) = 6 because a negative multiplied by a negative is a positive..

Now we have 6 + 20 which is 26, so 26 is your answer.
