simplified form of the expression (5.23x + 3.76) − (3.67x − 6.39)

Answers

Answer 1

[tex]5.23x + 3.76 - 3.67x + 6.39 \\ = 1.56x + 10.15[/tex]

Answer 2

Answer:

1.56x + 10.15

Step-by-step explanation:

(5.23x + 3.76) – (3.67x – 6.39)

(a + b) – (c – d) = a + b – c + d

Remove the parentheses and change the signs as needed:

5.23x + 3.76 – 3.67x + 6.39.

Group the like terms and simplify:

5.23x – 3.67x + 3.76 + 6.39

1.56x +10.15.

The simplified form of (5.23x + 3.76) – (3.67x – 6.39) is 1.56x + 10.15.

From a barrel of colored marbles , you randomly select 5 blue , 2 yellow , 3 red , 4 green , and 2 purple marbles. Find the expreimetal probability of randomly selecting a marble that is NOT yellow .

1. 9 / 16
2. 7 / 8
3. 8 / 9
4. 3 / 4

Answers

I think it's 7/8 because there's 16 marbles and 14 aren't blue so you have a 14/16 chance of not getting a yellow marble which simplifies to 7/8

Answer:

4/5

Step-by-step explanation:

From your experiment of drawing 20 marbles you now have a proportion of non-yellow marbles to total marbles and from that you can come up with an experimental probability that you'll draw a non-yellow marble.

P(not yellow) = 16/20

if the length of an arc is 12π inches and the radius of the circle us 10 inches, what is the measure of the arc?

Answers

You're dealing with "arc length" here, and the formula for that is s = r*theta, where r is the radius and theta is the central angle in radians (not degrees).

Thus, s = (12pi inches) = (10 inches)(theta), so

theta = the central angle (not the measure of the arc) = (12pi)/(10 inches), or

theta = 1.2*pi (no units of measurement)

Answer:

The measure of arc is 216°

Step-by-step explanation:

Length of arc, L = 12π inches

Radius of the circle, R = 10 inches

Formula: [tex]\theta=\dfrac{L}{R}[/tex]

Where, [tex]\theta[/tex] in radian.

By substituting L and R into formula.

[tex]\theta=\dfrac{12\pi}{10}[/tex]

[tex]\theta=\dfrac{6\pi}{5}[/tex]

Now we change radian to degree

[tex]\text{Degree }=\dfrac{\text{Radian}}{\pi}\times 180^\circ[/tex]

[tex]\text{Degree }=\dfrac{6\pi}{5\pi}\times 180^\circ[/tex]

Central angle = 216°

Hence, The measure of arc is 216°

What is the surface area of the regular pyramid

Answers

The total area is the sum of the area of the base (65 m^2) and six times the area of one of the triangular sides. This area (of one side) is (1/2)(base)(height), or (1/2)(5)(12), so the total area of the sides is 6(1/2)(5)(12) = 180 m^2. Thus, the total area is 65 m^2 + 180 m^2 = 245 m^2.

Anne plans to increase the prices of all the items in her store but 5%. To the nearest cent how much will an artist saved if the artist buys a canvas and a frame that each measures 24 by 36 in before the price increase goes into effect. 24/36 canvas price 22.80 and the frame price is 89.98

Answers

Final answer:

The artist will not save any money, but will end up paying $24.06 more after the price increase.

Explanation:

To find out how much the artist will save, we first need to calculate the original cost of the canvas and frame. The price of the canvas is $22.80 and the frame is $89.98. Next, we calculate the price increase of 5% for both the canvas and frame. To do this, we multiply the original prices by 0.05. After that, we add the price increase to the original prices to get the new prices. Finally, we subtract the new prices from the original prices to find the amount saved by the artist.

The calculations are as follows:

Canvas price increase: $22.80 x 0.05 = $1.14New canvas price: $22.80 + $1.14 = $23.94Frame price increase: $89.98 x 0.05 = $4.50New frame price: $89.98 + $4.50 = $94.48Amount saved: ($22.80 + $89.98) - ($23.94 + $94.48) = $94.36 - $118.42 = -$24.06

The artist will actually end up paying $24.06 more after the price increase, rather than saving any money.

What percent of the June budget was for babysitting and movies (to the nearest tenth)?

Answers

The monthly expenses are found below:

Mortgage - $752 Tim's Chevron - $23Johnny's Allowance - $8Electric - $176Jenny-babysitting - $12Movie - $14Dry Cleaning - $41Tithe - $85,Credit Card - $150Food - $101Phone - $45Water - $16 Car - $272

Adding all the expenses, will give us a total of $1695.

To get the percent which is allocated for movie and the baby sitting:

Add the amount for the two then divide that to the total then multiply it by 100%
= 12 + 14 / 1695 x 100%
= 26 / 1695 x 100%

The width of a large, rectangle-shaped tree farm is 1.9 kilometers. The best length of the farm is 4.4 kilometers. What is the best estimate of the area of the farm? Estimate 1.9 x 4.4

Answers

To make estimates, we usually round the numbers the nearest integer.
Since 1.9 is closest to 2 than it is to 1, the nearest integer of 1.9 is 2.
Similarly, since 4.4 is closest to 4 than it is to 5, the nearest integer of 4.4 is 4.

Now, to estimate the area of the farm, we are going to multiply our two integers:
Estimated Area of the Farm= [tex]2[/tex]x[tex]4=8[/tex]

Since 8 is between 4 and 10, we can conclude that the best estimate of the area of the farm is: between 4 and 10

If lines L and M are parallel in the given diagram and angle 5 is 132°, what is the measure of angle 3?

Answers

Hi,
The answer is 48 degrees.
How I got my answer:
Angle 5 + Angle 3 = 180(Co. Interior Angles)
let Angle 3 be x
132 + x = 180
x = 180 - 132
x = 48
The measure of Angle 3 is 48 degrees.
Hope this helps you.

Final answer:

Since lines L and M are parallel, corresponding angles such as angle 5 and angle 3 will be equal. Thus, if angle 5 is 132°, angle 3 will also be 132°.

Explanation:

This question concerns parallel lines and the angles formed by a transversal cutting across them. The lines L and M in the given diagram are parallel. Parallel lines have a special property where corresponding angles are equal. If angle 5 measures 132°, then the corresponding angle, angle 3, also measures 132°, because of this property of parallel lines.

Billy's plant grows at least 2 inches a month.

Answers

You would choose the arrow pointing to the right with a solid circle, and place it on the number line at the number positive 2.

Since his plant grows "at least" 2 inches per month, this means that it can grow that much or more. This is the same as the inequality "greater than or equal to."

Since the plant can grow 2 inches per month, the circle is filled in at 2. Since it can grow more than this, the arrow points to the right, which is the numbers greater than 2.

How many sides does a regular polygon have if each exterior angle measures 30?

Answers

Sum of exterior angles of every polygon irrespective of number of its sides is 360o . As it is a regular polygon, all exterior angles are equal and are 30o . Hence number of sides of the polygon is 360o30o=12.

The number of sides that the polygon with each exterior angle measuring 30° has is 12.

What is a polygon?

A polygon is a planar figure characterised by a limited number of straight-line segments joined to create a closed polygonal chain in geometry. A polygon is defined as a bounded planar region, a bounding circuit, or both.

The sum of all the exterior angles of a regular polygon is always equal to 360°. Therefore, the measure of an exterior angle for a regular polygon is given as,

[tex]\theta = \dfrac{360^o}{n}[/tex]

where n is the number of sides.

Given that the measure of the exterior angle is 30°. Therefore, the number of sides will be,

[tex]\theta = \dfrac{360^o}{n}\\\\ 30^o = \dfrac{360^o}{n}\\[/tex]

n = 12
