RS = 5x, ST = 3x, and RT = 48

What is RS?

Answer:

z = 8.2

Step-by-step explanation:

6.7z = 5.2z + 12.3

combine like terms by subtracting 5.2z from both sides

1.5z = 12.3

divide by 1.5

z = 8.2

Answer:

8.2

Step-by-step explanation:

5.2z+12.3=6.7z

12.3=6.7z-5.2z

12.3=1.5z

z=8.2

Answer:35.18

Step-by-step explanation:

Did this 7 years ago

The required value of 42.5 – 7.32 is 35.18.

Subtraction of 7.32 from 42.5 to be determined

Subtraction is defined as the value that should be reduced to the subtraction value.

Here, subtraction of 7.32 from 42.5,
⇒ 42.5 - 7.32
= 35.18

Thus, the required value of 42.5 – 7.32 is 35.18.

Answer:

1/35

Step-by-step explanation:

We can use proportion.

5 dresses --- 1/7

1 dress ----      x

x = 1*1/7: 5= 1/7 *1/5 = 1/35

Hey there! I'm happy to help!

We have 5 numbers that will give us an average score of 80.

75,82,71,84,x

What we do is add these all up and divide by 5 to get 80. Let's go backwards to find x.

We multiply by 5.

80(5)=400

We subtract all of the numbers except for x.

400-75-82-71-84=88

Therefore, the score on the next test has to be 88 to have the student's average be 80.

Answer:

No, it's not a one-to-one function

Step-by-step explanation:

Given

[tex]f(x) = round(x)[/tex]

Required

Determine if this function is one-to-one

I'll answer this question using the following illustrations;

Assume x = 4.6

[tex]f(x) = round(x)[/tex] would be

[tex]f(4.6) = round(4.6)[/tex]

[tex]f(4.6) = 5[/tex]

Also assume x = 4.8

[tex]f(x) = round(x)[/tex] would be

[tex]f(4.8) = round(4.8)[/tex]

[tex]f(4.8) = 5[/tex]

More generally;

[tex]4.5 \leq\ x\leq\5.4[/tex]

Would result in:

[tex]f(x) = 5[/tex]

Since, there's a always a possibility of f(x) having one value for various values of input x, then we can conclude that the function is not a one-to-one function

The function f(x) = round(x) is not one - to - one since different input values of X could yield the same output.

For instance :

Given that x = 1.4

f(x) = round(x)

f(1.4) = round(1.4)

Output = 1 ( nearest integer)

Since, different input values of X could yield the same the output, then the function is not one - to - one.

Answer:

x= 105

Step-by-step explanation:

Let the unknown angle at the base be y.  We know the base angles of an isosceles triangle are the same

The sum of the angles of the triangles are

30 + y +y = 180

30 + 2y = 180

2y = 180-30

2y = 150

y = 75

We know that x+y = 180 since it forms a straight line

x+75 =180

x = 180-75

x = 105

Answer:

285!

Step-by-step explanation:

First you have to find out how may parts are produced in a single minute.

We know that 114 parts are produced in 6 minutes so to find how may parts are made in one minute divide 114 by 6 and get an answer of 19

114÷6=19

Now to find how may parts are produced in 15 minutes multiply 19 (number of parts produdced in one minute) by 15 and get an answer of 285!

19×15=285

Answer: x=6.67

Step-by-step explanation:

Since these parallelograms are similar, we can use proportions to solve for x.

[tex]\frac{15}{9} =\frac{x}{4}[/tex]              [cross multiply]

[tex]60=9x[/tex]            [divide both sides by 9]

[tex]x=6.67[/tex]

Now, we know that x=6.67.

Answer:

20/3

Step-by-step explanation:

9/4=15/x

cross multiply and get:

9x=15x4

9x=60

divide both sides by 9 so

x=60/9 which when simplified is equal to 20/3

Answer:

v = 23.370 mph

Step-by-step explanation:

It is given that,

The world record for the 100 meter dash is finished in 9.572 seconds in Berlin. We need to find the Bolt’s average race speed in miles per hour.

We know that,

1 mile = 1.609 km

or

1 mile = 1609.34 m

⇒ 100 m = 0.0621 miles

1 hour = 3600 seconds

⇒ 1 second = (1/3600) hour

Average speed = distance/time

So,

[tex]v=\dfrac{\dfrac{100}{1609.34 }\text{miles}}{\dfrac{9.572}{3600}\ \text{hour}}\\\\v=23.36963\ \text{mph}[/tex]

or

v = 23.370 mph

Hence, Bolt’s average race speed is 23.370 mph.

Answer:

Step-by-step explanation:

Given the vectors  u = (1, −1, −2) and v = (1, 1, 2),

projection of u on v is expressed as [tex]proj_v u = \dfrac{u*v}{|v|^2}*v[/tex]

u.v = (1, −1, −2).(1, 1, 2)

u.v = 1(1)+(-1)(1)+(-2)(2)

u.v = 1-1-4

u.v = -4

|v| = √1²+1²+ 2²

|v| = √1+1+4

|v| = √6

|v|² = (√6)²

|v|² = 6

[tex]proj_v u = \dfrac{-4}{6}*(1,1,2)\\proj_v u = (\dfrac{-4}{6}, \dfrac{-4}{6}, \dfrac{-4}{3} )[/tex]

Similarly for projection of v on u;

[tex]proj_u v = \dfrac{u*v}{|u|^2}*u[/tex]

|u| = √1²+(-1)²+ (-2)²

|u| = √1+1+4

|u| = √6

|u|² = (√6)²

|u|² = 6

[tex]proj_u v = \dfrac{-4}{6}*(1,-1,-2)\\proj_u v = (\dfrac{-4}{6}, \dfrac{4}{6}, \dfrac{4}{3} )[/tex]

There is one factor: number of jumps.

This factor has two levels: sets of 10 and sets of 20.

Answer:

Area of the trapezoid = 18 m²

Step-by-step explanation:

Formula to calculate the area of a trapezoid is,

Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

Where [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides of the trapezoid

And h = distance between the parallel sides

From the figure attached,

[tex]b_1[/tex] = 5 m

[tex]b_2[/tex] = (6 + 1) = 7 m

h = 3 m

By substituting these values in the formula,

Area of a trapezoid = [tex]\frac{1}{2}(5+7)3[/tex]

                                 = 6 × 3

                                 = 18 m²

Therefore, area of the given trapezoid is 18 m².
