Answer:

20% increase

Step-by-step explanation:

We want to compute the percentage increase

Percent increase in price is expressed as

=(Change in price)/old price *100

=356.4-297/297*100

=59.4/297*100

=0.2*100

=20%

Answer:

  55°

Step-by-step explanation:

130° is an external angle to the small triangle at lower left, so is the sum of the remote interior angles. The unmarked interior angle at the bottom of that triangle is then 130° -30 = 100°.

That is an exterior angle of the large triangle that has remote interior angles of 45° and x°. So, ...

  x° + 45° = 100°

  x° = 100° -45°

  x° = 55°

_____

Alternate solution

The sum of the interior angles of a quadrilateral is 360°. Three of the angles in the bounding quadrilateral are x°, 45°, 30°. The fourth is the reflex angle that is (360° -130°) = 230°. So, we have ...

  x° +45° +230° +30° = 360° . . . . . angles CCW from lower right

  x° = 360° -305°

  x° = 55°

Answer:

[tex]Red = \frac{10}{37}[/tex]

Step-by-step explanation:

Given

[tex]Red:Yellow = 2 : 3[/tex]

[tex]Yellow: Blue = 5 : 4[/tex]

Required

Determine the fraction of Red

First, we need to link the given ratios.

Since yellow is present in both ratios, we start by making the ratio of yellow equal in both ratios

Multiply this ratio by 5

[tex]Red:Yellow = 2 : 3[/tex]

This becomes

[tex]Red:Yellow = 10 :15[/tex]

Similarly, multiply this ratio by 3

[tex]Yellow: Blue = 5 : 4[/tex]

This becomes

[tex]Yellow:Blue =15:12[/tex]

At this point, we have:

[tex]Red:Yellow = 10 :15[/tex] and [tex]Yellow:Blue =15:12[/tex]

Combine

[tex]Red:Yellow:Blue = 10:15:12[/tex]

The fraction is then calculated as:

[tex]Red = \frac{Red}{Red +Yellow + Blue}[/tex]

This gives

[tex]Red = \frac{10}{10+15+12}[/tex]

[tex]Red = \frac{10}{37}[/tex]

Answer:

y=-7x-2

Step-by-step explanation:

I assume you need the equation for the line, so that's what I'm solving for here.

1. Start by putting the slope and the coordinates into point slope form, which is y-y1=m(x-x1)

y+30=-7(x-4)

2. Distribute -7 to (x-4) (or multiply x and -4 by -7).

y+30=-7x+28

3. Subtract 30 from both sides to get y by itself.

y=-7x-2

Answer:

congruent, the triangles have 2 congruent sides and a congruent angle, therefore the triangles are congruent by the SAS Theorem

Step-by-step explanation:

5x-28 = 2x+8

3x=36

x=12

x+4 = 2x-8

(12)+4 = 2(12)-8

16 = 16, AB is congruent to DE

x-2 = 3x-26

(12)-2 = (36)-26

10 = 10, AC is congruent to DF

Answer:

Sine

Step-by-step explanation:

Using the Law of Sines, you can solve triangles when given two angles and a side.

Answer:

y=4/5x-5

Step-by-step explanation:

to find the slope intercept form (y=mx+b) we must find the slope(m) first. We take the two points given and use the slope formula (y2-y1/x2-x1) take the point (0,-5) as (x1,y1) and the point (5,-1) as (x2,y2).Using the slope formula {-1-(-5)/5-0}. We get the slope equal to 4/5. Now we have y= 4/5x+b.To find b we must choose one point from the given and substitute x and y in the formula we have(y=4/5x+b). I chose (0,-5) so substituting that, (-5=4/5(0)+b), and to finally get b=-5.Now substitute b in the equation y=4/5x+b to get y=4/5x-5.

Answer:

The equation that represents this problem is [tex]\frac{1}{2}[/tex] p - 2 = 18 ⇒ D

Step-by-step explanation:

Let us solve the question

∵ p is the time it takes Tomás to bike to the park

∵ The time it takes Tomás to bike to the community center is 2 minutes

   less than half the time it takes him to bike to the city park

→ That means multiply p by [tex]\frac{1}{2}[/tex] , then subtract 2 from it

∴ The time to the community center =  [tex]\frac{1}{2}[/tex] (p) - 2

∴ The time to the community center =  [tex]\frac{1}{2}[/tex] p - 2

∵ It takes Tomás 18 minutes to bike to the community center

→ Equate The time to the community center by 18

∴ [tex]\frac{1}{2}[/tex] p - 2 = 18

∴ The equation that represents this problem is  [tex]\frac{1}{2}[/tex] p - 2 = 18

Answer:

The unicycle will travel 351.68 inches in 7 revolutions

Step-by-step explanation:

The circular shape moves a distance equal to its circumference in each revolution, then the rule of the distance of the circular shape travels n turns is D = π d n, where

∵ A unicycle wheel has a diameter of 16 inches

∴ d = 16 inches

∵ The unicycle will travel 7 revolutions

∴ n = 7

→ Substitute them in the rule of the distance above

∵ D = π(16)(7)

∵ π = 3.14

∴ D = 3.14(16)(7)

∴ D = 351.68 inches

→ No need to round it, it is in the hundredth of an inch

∴ The unicycle will travel 351.68 inches in 7 revolutions

A .1/2      

[tex]\frac{1}{2} = 0.5[/tex]

B.2/4      

[tex]\frac{2}{4} = 0.5[/tex]

C.2/1    

[tex]\frac{2}{1} = 2[/tex]

D.2/2    

[tex]\frac{2}{2} = 1[/tex]

E.4/2

[tex]\frac{4}{2} = 2[/tex]

Answer:

$0.72

Step-by-step explanation:

In order to solve this question we need to know that 1% is one hundredth of something. Another important thing you need to understand is that when we are trying to find n% of y  we multiply just need to multiply "y" by [tex](\frac{n}{100} )[/tex]. In our case we have to find 6% of 12, in other word they are asking as the following "What is $12 times [tex](\frac{6}{100} )[/tex]?". So in order to find the answer we do the following..............

[tex]12 (\frac{6}{100} ) = \frac{(12)(6)}{100} = \frac{72}{100} = 0.72[/tex]
