What is the solution of -21 = n – 8?
a. n = -168
b. n = -29
c. n = -13
d. n = 168

Answer:

∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.

Step-by-step explanation:

From the picture attached,

p and q are the parallel lines and w is a transversal.

∠1 ≅ ∠3 [Vertically opposite angles]

∠1 ≅ ∠5 [Corresponding angles]

∠1 ≅ ∠7 [Alternate exterior angles]

Therefore, ∠2, ∠4, ∠6 and ∠8 are not congruent to ∠1.

The probability that Trey's card will be a heart or a black-suited card is

3/4

Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Deck of cards contains,

spade=13, heart=13, diamonds=13, clubs= 13

In which clubs and spades are black and hearts and diamonds are red.

Total (Black suited card with a heart) =26+13= 39

P( heart or a black-suited card)=39/52

                                                    =3/4.

Hence, probability of heart or a black-suited card is 3/4

Answer:8 and 5

Step-by-step explanation:8 times 5 is 40 and 5 is 3 less than 8

Answer:

80 servings

Step-by-step explanation:

there is 8 serving per bag

Answer:

80

Step-by-step explanation:

Let servings be s and the bag be b

s = 1/8 b

multiply both sides by 8

8s = b

For 10 bags, it will be 10*8s = 80s which is 80 servings.

Answer:

x ≥ 8

Step-by-step explanation:

Let x be the number of pounds he buys. As each pound costs 7 dollars and he must spend at least 56 dollars, we have:

7x ≥ 56

x ≥ 8 (divide each side by 7)

Thus, our answer is any number above 8.

=======================================================

Explanation:

Refer to the diagram below. The point (8,-15) is in quadrant 4, which is the southeast quadrant. A right triangle forms where the hypotenuse goes from the origin to the terminal point in question. After applying the pythagorean theorem, the hypotenuse is 17 units long.

Opposite the reference angle θ, greek letter theta, the side is -15. Usually negative lengths are not allowed and don't make any sense; however, I'm making this negative to ensure that sin(θ) ends up negative. This will help with other trig ratios as well.

So,

sin(angle) = opposite/hypotenuse

sin(θ) = -15/17

-----------------

The cosine ratio will involve the adjacent and hypotenuse

cos(angle) = adjacent/hypotenuse

cos(θ) = 8/17

------------------

Tangent is opposite over adjacent

tan(angle) = opposite/adjacent

tan(θ) = -15/8

------------------

The functions csc(θ), sec(θ), and cot(θ) are the functions cosecant, secant, and cotangent in that order.

They represent the reciprocal of sine, cosine, and tangent in that order as well.

Eg: sec(θ) is the reciprocal of cos(θ)

This means,

As an alternative, you could also say

------------------------

Here's a list of formulas that you can write down on a reference sheet

where h is the hypotenuse and h = sqrt(x^2+y^2). Notice that something like tan = y/x is the reciprocal of cot = x/y. The x and y refers to the coordinates of the terminal point given to you. Make sure to reduce all fractions as much as possible. In our case, none of the fractions can be reduced any further.

Answer:

70%

Step-by-step explanation: 35/50 equals 0.7

Answer:

70%

Step-by-step explanation:

The total number of marbles will be 35 + 8 + 7 = 50 marbles in total (all the colors added together). The probability of drawing a red marble will be the number of red marbles divided by the total marbles. This also fits the  probability formula of (desired outcomes)/(total number of outcomes. Thus, we have 35 red marbles and 50 marbles in total. So, we get 35/50, which is 70%.

Answer:

Step-by-step explanation:

The equation representing either purchase will multiply the number of items by their cost, for each item, and show the total as the cost of the purchase. Here, p is defined as the cost of a pretzel; g is defined as the cost of a granola bar.

Landon's purchase

 1 pretzel + 5 bars will cost 1p +5g

 That cost is 17.55, so the equation is ...

     p +5g = 17.55

Lesley's purchase

  4 pretzels + 2 gars will cost 4p +2g

  That cost is 13.50, so the equation is ...

     4p +2g = 13.50

__

To solve, you can subtract the second equation from 4 times the first:

  4(p +5g) -(4p +2g) = 4(17.55) -(13.50)

  18g = 56.70 . . . . collect terms

  g = 3.15 . . . . . . . . divide by 18

Then the cost of a pretzel can be found using the first equation.

  p + 5(3.15) = 17.55

  p = 1.80

The cost of a pretzel is $1.80; the cost of a granola bar is $3.15.

Step-by-step explanation:

Cost price of shirt after giving discounts is equals to [tex]\$68[/tex].

" Cost price is defined as the price to be paid at the time of purchase any product."

According to the question,

Initial cost price of shirt [tex]= \$100[/tex]

First discount [tex]= 15\%[/tex]

Discount amount [tex]= 15\%[/tex] of [tex]100[/tex]

                             [tex]= \frac{15}{100} \times 100\\\\= \$15[/tex]

Cost price after first discount [tex]= 100 - 15[/tex]

                                                 [tex]= \$85[/tex]

Second discount [tex]= 20\%[/tex]

Discount amount [tex]= 20\%[/tex] of [tex]85[/tex]

                             [tex]= \frac{20}{100} \times 85\\\\= \$17[/tex]

Cost price after first discount [tex]= 85 - 17[/tex]

                                                 [tex]= \$68[/tex]

Hence, cost price of shirt after giving discounts is equals to [tex]\$68[/tex].

Answer:

C (sorry if its incorrect)

Step-by-step explanation:

Answer:

9.03 = x

Step-by-step explanation:

Since we have the Hypotenuse given and we need to find the value of the adjacent side of the given angle we would use the Cosine Ratio;

Cos(46) = [tex]\frac{x}{13}[/tex]

To solve for "x" we would first have to isolate the "x" all to itself.

To isolate the variable, simply multiply 13 to the both sides of "="

=> Cos(46) * 13 = x

=> 9.03 = x

So you can write the answer in either of the 2 ways mentioned above, if you need a fully simplified answer the second answer would be a better fit. If u just need the Equation the 1st equation would be the better fit.

Answer:

Relation 1: Not a function

Relation 2: Not a function

Relation 3: Function

Relation 4: Not a function

Step-by-step explanation:

Recall: a relation can only be a function if and only if each domain value has only 1 range value mapped to it or related to it. This means that a domain value can only have exactly one range value for the relation to be qualified a function.

✔️Relation 1 is NOT A FUNCTION.

Rationale: Two of the domain values (star and sky) is having more than 1 range value assigned to each.

✔️Relation 2 is NOT A FUNCTION:

Rationale: domain value, 9, has several range values assigned to it.

✔️Relation 3 is A FUNCTION:

Rationale: each domain value do not have more than one range values assigned to it.

✔️Relation 4 IS NOT A FUNCTION:

Rationale: the domain value, 6, has two range values, m and d, assigned to it.

Answer:

  3x -2y = 12

Step-by-step explanation:

The constant in the standard form equation for a line is proportional to the distance of the line from the origin. Dilation by a factor of 2 moves the line to twice its original distance from the origin. The equation of the new line will have the constant 2×6 = 12:

  3x -2y = 12

_____

Additional comment

The actual distance of line ax+by=c from the origin is ...

  d = |c|/√(a²+b²)

The distance from any point in the plane to the line is ...

  d = |ax +by -c|/√(a²+b²)

The previous equation is for the special case of (x, y) = (0, 0), the distance from the origin.

Answer:

0.512 ; - 0.538

Step-by-step explanation:

Using the standard linear regression relation :

y = bx + c

b slope ; c = intercept ; y = dependent ; x = independent variable.

For finalist between 2004 - 2014 ;

y = 0.024x - 0.328

x = 35

y = 0.024(35) - 0.328

y = 0.512

For finalist between 1990 - 2014 ; with 14 winners ; change in daily circulation :

y = -0.015x - 0.328

x = 14.

y = -0.015(14) - 0.328

y = - 0.538

Answer:

{1, 2, 3},  {3, 4, 5}

Step-by-step explanation:

Write expressions for three consecutive integers:  n, n + 1, n + 2.

Set up an equation for the verbal description: the product (mulitplication) of the two larger integers (the last two) is one less than 7 times the smallest (the first one).

(n + 1)(n + 2) = 7n - 1

Multiply (FOIL) the left side.

n^2 + 3n + 2 = 7n - 1

Subtract 7n and subtract 1 to make the right side 0.

n^2 - 4n + 3 = 0

Factor.

(n - 1)(n - 3) = 0

Set the two factors equal to 0

n - 1 = 0,  n - 3 = 0

Solve for n.

n = 1,  n = 3

One set of integers begins with 1, so it's {1, 2, 3}.

The other set begins with 3, so it's {3, 4, 5}
