Answer:

a.) x=10

Step-by-step explanation:

3(10)+28= 30+28

58

5(10)+52= 50+52

102

2(10)-10= 20-10

10

58+102+10= 180

Answer:

add all of the angles which equals to 180 degree

being

3x + 28 + 5x + 52 + 2x + 10=180°

which is

10x + 90 = 180

x = 180-90/10

x=11

Answer:163 bpm

Step-by-step explanation:

The running heart rate of a girl as per linear equation will be 178.7 bpm.

Linear equation is an equation where the highest power of a variable is 1.

As per given data,

The average walking heart rate of eight girls is = (66 + 72 + 74 + 78 + 80 + 84 + 86 + 88)/ 8 = 78.5 bpm.

The average running heart rate of eight girls is = (128 + 136 + 134 + 138 + 142 + 144 + 14 8 + 152)/8 = 1122/8 = 140.25 bpm.

Therefore, for walking heart rate of x, the running heart rate will be (140.25/78.5)x = 1.787x.

Hence, the linear equation between walking heart rate and running heart rate is y = 1.787x.

Now, for walking heart rate of 100 bpm of a girl, the running heart rate will be = 1.787 × 100 bpm = 1787.7 bpm.

mark me as brainliest and follow me

Step-by-step explanation:

1. First calculate for the gradient m

2. Calculate for the constant C by using any point (0,3) or (3,9)

3. Lastly, put the values found in the equation y = mx + c

1. m = Y2-Y1/X2-X1

=9-3/3-0=2

2. input one point together with m into the equation y=mx+c

3=2(0)+C

C=3

3. Therefore equation of linear relationship is

y = 2x + 3

8 car's for 88$ the same thing for the 6 car's for 66$

Answer:

Laura washed 8 cars to earn $ 88

Step-by-step explanation:

Number of cars : earnings = 6 : 66

6 : 66 :: x : 88

Product of mean  = Product of extremes

 66 * x = 6 *88

        x = [tex]\frac{6*88}{66} = \frac{1*88}{11}[/tex]

Answer:

C. 4/3

Step-by-step explanation:

The value of tan(2x) is -4/3

Let, 'm' be an angle then the double angle formula of tan is,

[tex]tan(2m)=\frac{2~tan(m)}{1-tan^{2}m }[/tex]

For given example,

We have cos(x) = 1/√5 and sin(x) > 0

We know, sin^2(x) + cos^(x) = 1

⇒ sin^2(x) = 1 - (1/√5)^2

⇒ sin^2(x) = 1 - (1/5)

⇒ sin^2(x) = 4/5

⇒ sin(x) = ± 2/√5

But sin(X) > 0

⇒ sin(x) = 2/√5

We know, for any angle Ф,

tan(Ф) = sin(Ф) / cos(Ф)

Hence, tan(x) = sin(x)/cos(x)

tan(x) = (2/√5) / (1/√5)

⇒ tan(x) = 2/1

⇒ tan(x) = 2

Now, using the double angle formula for tan,

[tex]\Rightarrow tan(2x)=\frac{2~tan(x)}{1-tan^{2}x }\\\\\Rightarrow tan(2x)=\frac{2\times 2}{1-(2)^{2}}\\\\ \Rightarrow tan(2x)=\frac{4}{1-4}\\\\ \Rightarrow \bold{tan(2x)=-\frac{4}{3}}[/tex]

Therefore, the value of tan(2x) is -4/3

Answer:

240 miles

Step-by-step explanation:

Given that:

Charges offered by Prestige car rentals for renting a midsize vehicle:

Fixed charges = $47

Per mile charges for renting a midsize vehicle = $0.07

Charges offered by Gateway Auto for renting a midsize vehicle:

Fixed charges = $35

Per mile charges for renting a midsize vehicle = $0.12

To find:

Number of miles for which both the companies charge the same price?

Solution:

Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles

Charges for one mile by Prestige car rentals = $0.07

Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]

Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]

Charges for one mile by Gateway Auto = $0.12

Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]

Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]

As per question statement, the charges are same:

[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]

Answer:

to find the total number of miles traveled, you have to add the total distance from point L to point M together. 929+ 595 = 1,524 total miles traveled

to find the average miles per hour, you divide the total miles traveled, by the amount of time it took. 1,524 / 3 = 508 miles per hour
