Step-by-step explanation:

tan(z) = 10/8

z = (tan^-1)(1.25)

z = 51.3401917459

Answer:

D) 51

Step-by-step explanation:

Form an equation to find z:

tan(z)=10/8

tan^-1(tan(z))=tan^-1(10/8)

Answer:

[tex]y = 2x - 2[/tex]

Step-by-step explanation:

You have not attached the graph.

Assuming the graph function is the one shown in the attachment.

The equation is given by

[tex] \frac{x}{a} + \frac{y}{b} = 1[/tex]

where a=1 is the x-intercept and b=-2 is the y-intercept.

We substitute to get:

[tex] \frac{x}{1} + \frac{y}{ - 2} = 1[/tex]

[tex]2x - y = - 2[/tex]

or

[tex]y = 2x - 2[/tex]

The solutions to f(x) = 64 is x = 7 and x = –7.

Solution:

Given data:

[tex]$f(x)=x^{2}+15[/tex] – – – – (1)

[tex]f(x)=64[/tex] – – – – (2)

To find the solutions to f(x) = 64.

Equate equation (1) and (2), we get

[tex]x^2+15=64[/tex]

Subtract 15 from both sides of the equation.

[tex]x^2+15-15=64-15[/tex]

[tex]x^2=49[/tex]

[tex]x^2=7^2[/tex]

Taking square root on both sides of the equation, we get

x = ±7

The solutions to f(x) = 64 is x = 7 and x = –7.

The probability that the card is not yellow is [tex]\frac{5}{9}[/tex]

Solution:

The probability of an event is given as:

[tex]Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}[/tex]

From given,

A box is filled with 8 blue cards, 8 yellow cards, and 2 green cards

Total number of possible outcomes = 8 + 8 + 2 = 18

Favorable outcome = card is not yellow

Favorable outcome = card is blue or green = 8 + 2 = 10

Therefore,

[tex]Probability = \frac{10}{18}\\\\Probability = \frac{5}{9}[/tex]

Thus the probability that the card is not yellow is 5/9

The probability that the chosen card is not yellow  =   [tex]\frac{5}{9}[/tex]

Step-by-step explanation:

Step 1 :

Given,

Number of blue cards in the box = 8

Number of yellow cards in the box = 8

Number of green cards in the box = 2

Hence total number of cards =  18

We need to find the probability that the chosen card is not yellow.

Step 2 :

Probability that the selected card is yellow = [tex]\frac{8}{18}[/tex] = [tex]\frac{4}{9}[/tex]  [since the favorable outcome = 8 and total outcome = 18]

Hence the probability of chosen card not being yellow  = 1 -  [tex]\frac{4}{9}[/tex] =  [tex]\frac{5}{9}[/tex]

Step 3 :

Answer :

The probability of chosen card not being yellow  =   [tex]\frac{5}{9}[/tex]

Answer:

12

Step-by-step explanation:

4:1:1, from the ratio, you know that there are 6 in total (4+1+1)

so set up a proportion

(4/6) = (48/x)

so... (6 x 48) / 4 = x

x = 72, the total

now repeat to find the value for Pip

(1/6) = (x/72)

72 / 6 = 12

Final answer:

Paul, Fiona, and Pip share sweets in a 4:1:1 ratio. Paul's 4 parts amount to 48 sweets, so each part is 12 sweets. Consequently, Pip receives 12 sweets.

Explanation:

The student's question is asking how many sweets Pip would get if Paul, Fiona, and Pip share some sweets in the ratio 4:1:1 and Paul gets 48 sweets. To solve this, we'll need to break down the problem and figure out how many parts the total number of sweets is being divided into. Then, we'll calculate the number of sweets per part using the information given.

Since the ratio is 4:1:1, there are a total of 4 + 1 + 1 = 6 parts. Paul's share is 4 parts, and since Paul gets 48 sweets, each part is worth 48 sweets ÷ 4 parts = 12 sweets.

Both Fiona and Pip get 1 part each. So, since each part equals 12 sweets, Pip gets 12 sweets.

The ladder in figure 2 reaches 3.2 feet further up than the ladder in figure 1.

Step-by-step explanation:

Step 1:

In both the given figures, the ladder, the wall and the floor form a right-angled triangle. The floor is the adjacent side, the wall is the opposite side and the ladder is the hypotenuse.

According to the Pythagorean theorem,

[tex]a^{2}+b^{2}=c^{2}[/tex], where c is the length of the hypotenuse while a and b are the lengths of the other two sides.

Step 2:

For the ladder in figure 1, assume the distance from the floor to the ladder's top is x feet. So a = x, b = 8 and c = 10 (hypotenuse).

[tex]a^{2}+b^{2}=c^{2}[/tex], [tex]x^{2}+8^{2}=10^{2}[/tex], [tex]x^{2}=100-64=36, x=\sqrt{36}=6 \text { feet }[/tex].

So the distance between the floor and the ladder's top is 6 feet.

Step 3:

For the ladder in figure 2, assume the distance between the floor and the ladder's top is y feet. So a = y, b = 4 and c = 10 (hypotenuse).

[tex]a^{2}+b^{2}=c^{2}[/tex], [tex]y^{2}+4^{2}=10^{2}[/tex], [tex]y^{2}=100-16=48, x=\sqrt{84}=9.1651 \text { feet }[/tex].

So the distance between the floor and the ladder's top is 9.1651 feet.

Step 4:

The difference in heights = The wall height in figure 2 - the wall height in figure 1.

The difference in heights = 9.1651 feet - 6 feet = 3.1651 feet.

Rounding this off to the nearest tenth of a foot, we get 3.2 feet.

Answer: 0.18

Step-by-step explanation:

18 hundredths means that if you divide something into one hundred equal parts, 18 hundredths is 18 of those parts that you just divided up. Since 18 hundredths is 18 over one hundred, 18 hundredths as a Fraction is 18/100. If you divide 18 by one hundred you get 18 hundredths as a decimal which is 0.18.

The area of the given trapezoid is 60 square inches.

Step-by-step explanation:

Step 1:

The trapezoid's area is calculated by adding the base lengths and multiplying it with the trapezoid's height and [tex]\frac{1}{2} .[/tex]

The trapezoid's area, [tex]A = (sum of the lengths)(\frac{height}{2})[/tex]

Here the sum of the base lengths is given as 15 inches.

Step 2:

In the given problem, the sum of the base lengths is 15 inches and the height of the trapezoid is 8 inches.

The trapezoid's area [tex]A = (15)(\frac{8}{2} )= (15)(4) = 60.[/tex]

So the area of the given trapezoid is 60 square inches.

Answer:

median 8, interquartile range 13

Step-by-step explanation:

Step-by-step explanation:

The centroid divides the length of each median in 2:1 ratio.

The length of the part between the vertex and the centroid is twice the length between the centroid and the mid-point of the opposite side.

When CD is the median, C is the vertex and D is the midpoint of AE.

Answer: 96 ordered pair form : (9, 6)

Step-by-step explanation:

x + y = 15

1x + 1y = 15

-1x

y = 15 - 1x (we did this so that it can be the in y=mx format)

3y = 2x (substitute the y for the solution above)

3 ( 15 - 1x ) = 2x

45 - 3x = 2x

+3x +3x

45 = 5x (divide 5 on both sides)

45/5 = 9 ; x = 9

now go back to the first equation and substitute the x for 9

y = 15 - 1(9)

y = 15 - 9

y = 6

A) S, Q, and B

Hope that help you!

Answer:

S, Q and B

Step-by-step explanation:

Those are the angles.

For this case we must factor the following expression:

[tex]-x ^ 2 + 2x + 35[/tex]

We take common factor -1, taking into account that [tex]- * - = +:[/tex]

[tex]-1 (x ^ 2-2x-35)[/tex]

We factor the expression within the parenthesis, for this we look for two numbers that, when multiplied, result in -35 and when added, result in -2. These numbers are -7 and +5.

[tex]-7 + 5 = -2\\-7 * 5 = -35[/tex]

Thus, the factored expression is:

[tex]((x-7) (x + 5))[/tex]

Finally we have:

[tex]- (x-7) (x + 5)[/tex]
