The mean is 60, and the median is 64

suter [353]2 years ago

7 0

Answer:

1 median=60.3

2 missing number=38

Step-by-step explanation:

1 45+55+76+y+88+54/6

316+y/6=63.6

316+x381.6

x=381.6-316=65.6

2M4 =63

60-62+92+x/4=63

214+x=252

x=252-214

=38

△HFM∼△PST

loris [4]

Answer:

The perimeter of △HFM is 50.75 units

Step-by-step explanation:

The correct picture of the question in the attached figure

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

we have

△HFM∼△PST ----> given problem

step 1

Find the scale factor

Let

z ----> the scale factor

$z=\frac{HF}{PS}$

substitute the given values

$z=\frac{14}{8}=1.75$

step 2

Find the perimeter of triangle PST

Remember that the perimeter of a triangle is the sum of its three length sides

$P=8+9+12=29\ units$

step 3

Find the perimeter of triangle HFM

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

The perimeter of triangle HFM is equal to the perimeter of triangle PST multiplied by the scale factor

$29(1.75)=50.75\ units$

Please show me how you find the measure of side b and what b measures

Dovator [93]

Answer:

b = 252 in

Step-by-step explanation:

cos theta = adjacent side over hypotenuse

cos 38 = b/ 320

Multiply each side by 320

320 cos 38= b/320 * 320

320 cos 38 = b

252.1634412 =b

To the nearest whole number

252 =b

Suppose a2 + 4a + 3 represents the area of a rectangle. What is the perimeter of that rectangle? A) 2a + 4 B) 4a + 8 C) 6a + 12

allsm [11]

A² + 4a + 3
(a+3)(a+1) This is the length and the width of the rectangle.

Perimeter = length + length + width + width
P = (a+3) + (a+3) + (a+1) + (a+1)
P = a + a + a + a + 3 + 3 + 1 + 1
P = 4a + 6 + 2
P = 4a + 8

B) 4a + 8

ILL GIVE BRAINLIEST IF YOU GET IT CORRECT AND EXPLAIN

nignag [31]

Answer: so a can be -2 and b can be 6, note that there are many combinations since u can factor all types of stuff out including fractions

Step-by-step explanation:

a(bx+3) basically is just factoring out a random common factor between -12x and -18

so we can factor out a -2 to get -2(6x+9)
