The number of pennies that Ari has is 14.

The number of nickels that Ari has is 8.

The linear equations that represent this question are:

0.01p + 0.05n = $0.54 equation 1

p + n = 22 equation 2

Where:

In order to determine the number of nickels, multiply equation 2 by 0.01

0.01p + 0.01n = 0.22 equation 3

Subtract equation 3 from equation 1:

0.04n = 0.32

Divide both sides by 0.04

n = 0.32 / 0.04

n = 8

Substitute for n in equation 2:

8 + p = 22

p = 22 - 8

p = 14

Step-by-step explanation:

thats it

0.898 rounded to nearest hundred will be 0.90 .

Given,

Number = 0.898

The unknow angles are as follows:

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.

Therefore,

m∠4 = 72 degrees

Hence,

m∠1 + m∠4 = 180 (angle on a straight line)

m∠1 = 180 - 72

m∠1 = 108 degrees

m∠2 = m∠4 (vertically opposite angles)

Vertical angles are the angles formed when two lines intersect each other. Vertical angles are congruent.

Therefore,

m∠2 = 72 degrees

m∠5 = m∠1 (corresponding angles)

Corresponding angles are angles that occur on the same side of the transversal line and are equal in size.

m∠5 = 108 degrees.

m∠7 = m∠5(vertically opposite angles)

m∠7 = 108 degrees

m∠8 = m∠2 (alternate exterior angles)

Alternate exterior angles are congruent.

m∠8 = 72 degrees

Answer:

geometric sequence

Step-by-step explanation:

an arithmetic sequence has a common difference d between consecutive terms.

40 - 200 = - 160

8 - 40 = - 32

no common difference thus not arithmetic

a geometric sequence has a common ratio r between consecutive terms

[tex]\frac{40}{200}[/tex] = [tex]\frac{4}{20}[/tex] = [tex]\frac{1}{5}[/tex]

[tex]\frac{8}{40}[/tex] = [tex]\frac{1}{5}[/tex]

thus there is a common ratio so sequence is geometric

Answer: y = -3x + 6

Step-by-step explanation:

If it is perpendicular to the line -3x + 2, then it's slope should also be -3.

The standard form of a line is y = mx + b. As our slope is -3, we have that our line is y = -3x+b. Now, let's put the given point into the line. x = 3 and y = -3, so -3 = -3*3 + b. Hence, b = -3+9 = 6. The equation of the line is y = -3x + 6.

Based on the commission percentage that William makes when he sells goods at the electronics store, the amount that William made in commission from the computer is $ 45. 84.

Commission made on goods and services are a percentage that is paid to sales people when they make a certain number of sales. The commission is based on the amount that the good or service in question is sold for.

The commission to William here can be found by the formula:

= Percentage made for commission on everything sold x Amount that the computer sold for

Solving for the commission to William gives:

= 6 % x 764

= 0. 06 x 764

Any question that may be answered statistically is one for which data collection is possible and for which there will be some degree of data variability. Because there is no variability in the data used to answer the question, questions that can only be answered with a single data point are not statistical questions.

Answer:

267,168 inches

Step-by-step explanation:

If your box is a rectangular prism or a cube, the only information you need is the box's length, width, and height. You can then multiply them together to get volume. This formula is often abbreviated as V = l x w x h.

Volume = L × W × H

Where,

Volume = 22 inches × 12 inches × 1012 inches

Volume = 267,168 inches

The transformation that takes place on the parent function ( f (x) = log (x) ) to achieve the graph of g(x)=log(-3x+9)+4  can be described as a reflection across the y-axis. Then you horizontally shrink a factor of three; shift three units to the right, and shift four units upwards.

Step 1: The parent graph is to be translated 3 units to the right side to achieve: y = log (x-3)

2. Shrink the graph by a factor of three by multiplying x by three:

⇒ y = log 3(x-3)

3. Reflect the function y = log 3(x-3) across line -3 = x to achieve:
y = -3(x-3)

4. Translate the function y = log 1-3(x-3) four units upwards to achieve

y = log (-3 + 9) +4

Answer:

-1/4 Abs(x+12) + 10

Step-by-step explanation:

The vertex form of an absolute function is of the form
y = a|x -h| + k   here |x-h| is the absolute value
where (h, k) are the coordinates (x, y) of the vertex

The vertex is given as (-12, 10)

So h = -12, k = 10

Plugging these in we get the vertex form as

y = a|x - (-12)| + 10

y = a|x + 12| + 10

All it remains is to find a

Given point (4, 6) as a point on the graph, plug these values
y = 6 = a|4 + 12| + 10

6 = a|16| + 10

6 = 16a + 10      since absolute value of a positive number is the number

Switch sides
16a + 10  = 6

Subtract 10 from both sides:
16a + 10 - 10 = 6 - 10
16a = -4
a = -1/4

So the equation of the function is
y = -1/4|x + 12| + 10

The second point is not needed to derive the function equation but let's use it to verify our calculated equation

Point (-8, 9)
Plug x = -8,  into y = -1/4|x + 12| + 10

=> y = -1/4|-8+12| + 10
=> y = -(1/4)·4 + 10

=> y = -1 + 10

= y = 9 which matches with the y -coordinate of the second point

So everything looks cool

Final Solution
-1/4 Abs(x+12) + 10

300=5x^2

x^2=60

x=7.74

7.74(5)=38.7

dimensions are 38.7ft by 7.74 ft

Please mark as brainliest

Step-by-step explanation:

the area of a rectangle is

length × width = 300 ft²

length = width + 5

(width + 5) × width = 300

width² + 5×width = 300

width² + 5×width - 300 = 0

the general solution to such a quadratic equation is

width = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 5

c = -300

width = (-5 ± sqrt(5² - 4×1×-300))/(2×1) =

= (-5 ± sqrt(25 + 1200))/2 =

= (-5 ± sqrt(1225))/2 = (-5 ± 35)/2

width1 = (-5 + 35)/2 = 30/2 = 15 ft

width2 = (-5 - 35)/2 = -40/2 = -20 ft

negative lengths for an actual object don't make sense, so width = 15 ft is our solution.

length = width + 5 = 15 + 5 = 20 ft

By the Law of Sines,

[tex]\frac{\sin B}{b}=\frac{\sin A}{a} \\ \\ \sin B=\frac{b \sin A}{a} \\ \\ =\frac{244\sin 37.8^{\circ}}{229} \\ \\ B \approx 37.42^{\circ}, 142.58^{\circ}[/tex]

Of these, only 37.42° is a possible value of B (sum of angles of a triangle is 180°).

So, we have that:

[tex] a=229, b=244, A=37.8^{\circ}, B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]

Angles of a triangle add to 180°, so:

[tex]C=180^{\circ}-A-B=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)

[/tex]

Using the Law of Sines again,

[tex]\frac{c}{\sin C}=\frac{a}{\sin A} \\ \\ c=\frac{a \sin C}{\sin A} \\ \\ =\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}}[/tex]

So, there is one possible triangle, where:

[tex]a=229 \\ \\ b=244 \\ \\ c=\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}} \\ \\ A=37.8^{\circ} \\ \\ B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right) \\ \\ C=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]
