Damm [24]2 years ago
5 0

Answer:

a) scale factor = 1.5

b) d length is 7.5

c) Area scale factor is 2.25

Step-by-step explanation:

Given QR =6

And ST =9

Length Scalar factor = enlarged length /previous length

 =9/6

 =1.5

Length Scalar factor =1.5

b)we know PS enlarged length of PQ

Length scale factor = PS/PQ

1.5 =PS/5

PS =5×1.5

PS =d =7.5

d length is 7.5

c)Formula :

Area scale factor = (length scale factor)2

=(1.5)2

=2.25

Area scale factor is 2.25

What is the value of x? And what is the missing angle value?
DanielleElmas [232]
These angles, 110º and 7xº, are examples of supplementary angles.
Supplementary angles are angles that, when added together, produce a sum of 180º.
This means 110º + 7xº = 180º.

With this equation, 110º + 7xº = 180º, we can isolate the variable and solve for x to answer this question.

110º + 7xº = 180º
The first step to solve for x is to subtract 110º from both sides of the equation.
110º + 7xº - 110º = 7xº
180º - 110º = 70º

7xº = 70º
Since we want 1xº instead of 7xº, we need to divide both sides by 7.
7xº / 7 = xº
70º / 7 = 10º

xº = 10º
Now we have our solution!
The value of x is 10º.

Let's check this to be sure.
7xº, when added to 110º, must equal 180º since 7xº and 110º are supplementary angles.
7xº + 110º = 180º
We found that x is 10º.
7(10)º + 110º = 180º
7 • 10 = 70
70º + 110º = 180º
180º = 180º
This works! That means that x = 10º is in fact the correct answer.

Answer:
x = 10º

Hope this helps!

Answer:

  √52 units

Step-by-step explanation:

The segment MN is the hypotenuse of a right triangle that is 6 units wide and 4 units high. The Pythagorean theorem tells you its length is ...

  MN = √(6² +4²) = √(36 +16)

  MN = √52

Jonathan ran five days a week. The most he ran in one day was 3.5 miles. Write an inequality that shows the distance jonathan co
natka813 [3]

Answer: x\leq17.5


Step-by-step explanation:

Given: The number of days Jonathan ran =  5

The most he ran in 1 day = 3.5 miles

Therefore, the maximum distance he ran in a week= 5\times3.5=17.5\ miles

Let x be the distance  Jonathan could have rum in a week, such that

x\leq17.5

Hence, the required inequality is x\leq17.5.
