find the measurement of the missing angles

Answer:

A.) 40°

Step-by-step explanation:

A triangle is equal to 180°

Angle X and Y has the same angle, so both have 70°.

So:

70° × 2= 140°

To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.

So:

180° - 140°= 40°

Answer= 40°

Answer:

[tex]y = (100-10x)\%[/tex]

It takes 10 minutes to the park.

Step-by-step explanation:

Given that:

Time taken = 6 minutes

Distance left to be traveled = 40%

To find:

The equation to represent the distance [tex]y[/tex], that still needs to be traveled after [tex]x[/tex] minutes.

Solution:

As per given statement, distance traveled in 6 minutes = 60%

We can say that:

Distance traveled each minute = [tex]\frac{60\%}{6}[/tex] = 10%

After 1 minute, distance traveled = 10%

Distance left = 100 - 10 = 90%

After 2 minutes, distance traveled = 20%

Distance left = 100 - 20 = 80%

After [tex]x[/tex] minutes, distance traveled = 10[tex]x[/tex]%

Distance left, [tex]y[/tex] = (100 - 10[tex]x[/tex])%

Therefore, the equation is:

[tex]y = (100-10x)\%[/tex]

Time taken by the bike to reach to the park can be found by putting [tex]y[/tex] = 0 (i.e. distance left to be traveled = 0)

[tex]0 = 100 -10x\\\Rightarrow 10x = 100\\\Rightarrow x = \bold{10\ minutes}[/tex]

Step-by-step explanation:

Find the 3rd angle in the triangle, let's call it y

36 + 73 + y = 180

109 + y = 180

y= 71

y is equivalent to x by vertical angles theorem

x= 71

2nd way

Use exterior angles theorem

180 - (36+73) = x

180 - 109 = x

71 = x

I hope this helps!!!

Answer:

x= 71 is the correct answer

Given:

The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1).

To find:

The vertices of the image reflected across the y-axis.

Solution:

The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1). It is reflected across the y-axis.

If a figure is reflected across the y-axis, then

[tex](x,y)\to (-x,y)[/tex]

Using this rule, we get

[tex]P(4,1)\to P_1(-4,1)[/tex]

[tex]Q(2,-8)\to Q_1(-2,-8)[/tex]

[tex]R(-8,1)\to R_1(8,1)[/tex]

So, the vertices of the image are [tex]P_1(-4,1), Q_1(-2,-8), R_1(8,1)[/tex].

Therefore, the correct option is B.

Note: Options are not in proper form.

Answer:

P'(–4, 1), Q'(–2, –8), and R'(8, 1)

Answer:

D. 1 1/2 hours

Step-by-step explanation:

First, we need to find the unit rate to then multiply it by 90. to find the unit rate I did 240 miles divided by 4 hours to get 60 miles per hour. So we know we need at least 1 hour to get the 60 miles and to get 90 miles we need to add 30. Since 30 is half of 60 we can just take half of 1 hour which is 30 minutes. we add it together and get 1 hour and 30 minutes, or 1 hour and a half.

Time taken to cover 90 miles is 1.5 hours

Time taken to cover 240 miles = 4 hours

Time taken to cover 90 miles

Time taken to cover 90 miles = [90 / 240]4

Time taken to cover 90 miles = [360 / 240]

Time taken to cover 90 miles = 1.5 hours

Step-by-step explanation:

Given the equations

-9x + y =  71.... 1

-x - y = -1 .... 2

Using elimination method we can eliminate y first since they have the same coefficient.

To do that we will need to add up both equations. We are adding because the coefficient of y in both equations has different signs. If they have the same sign, we would have subtracted.

Hence the correct option in this case is to add to eliminate y.

Answer:

As a percent: 115%

As a decimal: 1.15

As a fraction: [tex]\frac{23}{20}[/tex]

Step-by-step explanation:

Percentages

Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.

Thus, he is really paying 100%+15% = 115% of the original price.

To express a percentage as a decimal, we just divide by 100:

115% = 115/100 = 1.15

The same division should be simplified instead of operated to express the percentage as a fraction:

115% = [tex]\frac{115}{100}[/tex]

Simplifying by 5:

115% = [tex]\frac{23}{20}[/tex]

Summarizing:

As a percent: 115%

As a decimal: 1.15

As a fraction: [tex]\frac{23}{20}[/tex]

Answer:

22/3

Step-by-step explanation:

Part a)

Given the expression

[tex]54m^3n\:+\:81m^4n^2[/tex]

Apply exponent rule:    [tex]a^{b+c}=a^ba^c[/tex]

[tex]54m^3n\:+\:81m^4n^2=54m^3n+81m^3mnn[/tex]     ∵ [tex]m^4n^2=m^3mnn[/tex]

Rewrite 81 as 3 · 27

Rewrite 54 as 2 · 27

                             [tex]=2\cdot \:27m^3n+3\cdot \:27m^3mnn[/tex]

Factor out the common term:   27m³n

                              [tex]=27m^3n\left(2+3mn\right)[/tex]      

Therefore,

[tex]54m^3n\:+\:81m^4n^2=54m^3n+81m^3mnn=27m^3n\left(2+3mn\right)[/tex]

Part B)

Given the expression

[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z[/tex]

Apply exponent rule:    [tex]a^{b+c}=a^ba^c[/tex]

[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z=15x^2y^2yz+25x^2xy^2z+35x^2y^2z[/tex]

Rewrite as

                                               [tex]=3\cdot \:5y^2x^2zy+5\cdot \:5y^2x^2zx+7\cdot \:5y^2x^2z[/tex]

Factor out common term 5y²x²z

                                                [tex]=5y^2x^2z\left(3y+5x+7\right)[/tex]

Therefore,

[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z=5y^2x^2z\left(3y+5x+7\right)[/tex]

The dimension of the larger bin is x and the smaller bin is [tex]0.75x[/tex].

Step-by-step explanation:

Let the dimension of the larger bin is x.

It is given that the dimension of the smaller bin can be found by dilating the dimension of the larger bin by a scale factor of 0.75

In order to find the dimension of the smaller bin multiply the dimension of the larger bin by 0.75

[tex](x)(0.75)=0.75x[/tex]

Hence, the dimension of the larger bin is x and the smaller bin is [tex]0.75x[/tex].
