Answer:

x = 3/5√10

y = 2√10

Step-by-step explanation:

using the Pythagorean theorem:

y² = 7² - 3² = 49 - 9

y² = 40

y = 2√10

3/4.5 = y/5x

4.5y = 15x

substitute for y:

4.5(2√10) = 15x

15x = 9√10

divide both sides of the equation by 15:

x = (9√10)/15 = 3/5√10

Answer:

Answer:

There was no change in the length of June's scarf, that is, the length of it remained the same.

Step-by-step explanation:

Since Sue knitted a scarf for her friend June that was also 4 feet long and, after a month, the length of June's scarf could be represented by the expression 3/3 x 4, to determine how did the length of June's scarf change you must perform the following calculation:

Month 1 = 4

Month 2 = 3/3 x 4 = 1 x 4 = 4

Therefore, as can be seen, there was no change in the length of June's scarf, that is, the length of it remained the same.

Answer:

D. 14448

Step-by-step explanation:

S = Base area + lateral surface area

  =2*(1/2*(56*42)) + (56+42+70)*72

  = 2352 + 12096

  = 14448

Answer:

Step-by-step explanation:

EDGE

Answer:

= 41.32N  

To find N amount

You find the kg weight then times it by 10 then divide that amount by 1/2

So that 180pounds = 81.6466 x 10kg

x10 = 816.466

81.6466 / 2 = 40.8233

sin(30) = 40.8233/T

T =  40.8233/sin (30) =  N / sin(30) = Tension = calculator = -41.3178070464 = 41.32 N

Answer:

(5,27)

Step-by-step explanation:

parabolas are symmetrical around the vertex. therefore x axis crossing points are equidistant from the vertex.

f(x) cross x axis when x=2 and x=8

the mid point of 2 and 8 is 5.

f(5)=-3(5-2)(5-8)

f(5)=27

vertex=(5,27)

Answer:

The scale factor describes the size of an enlargement or reduction. For example, a scale factor of means that the new shape is twice the size of the original. Reduce means to make smaller, to lessen a amount.

Step-by-step explanation:

An example of a scale factor of reduction is 1:25

Enlarging scale means that the drawing is larger than the actual object. Hence the representative fraction will be greater than unity. For reducing scale the representative fraction is less than unity.

So now looking at 1:25, we see it's a reduction scaling because it's fraction is less than unity.

And what 1:25 means is that 1 on paper while the actual size of the object is 25

Answer:72

Step-by-step explanation:

72+37=109

180-109=72

I IS MATH

Answer:

72°+37°+x°=180°(being exterior angles)

109°+x°=180°

x°=180°-109°

x°=71°

Answer:

The length would be 9cm

Step-by-step explanation:

Because the perimeter is 76, you have to add 29 to 29 which equals 58, then you have to subtract 58 from 76, which is 18. The last episode is divide 18 by 2 because re are two sides remaining. So  answer would be 9. To check the answer you can add 29+29+9+9

Answer:

Answer:

1. c = 5.75b + 25

2. y = -1/3 + 5

3. y = -1/2 + 5

4. y = I can't tell what the numbers are from the photo, but (B) will be where the line is on the y axis of the graph.

Y = MX + (B)

Edit: Okay assuming the graph is going in the directions by one, meaning 1, 2, 3, or -1, -2, -3, and not any other sequence.

The answer for question will be y = 1/2x -1

Answer:

D. X = 130 in.

Step-by-step explanation:

a² +b² =c² (Pythagorean theorem)

50² + 120²=c²

2,500 + 14,400 =c²

16,900 = c²

√16900 = √c²

130 = c

X = 130 in.

Answer:

x=.5, y=-5.5

Step-by-step explanation:

7x+y=5, 7x+y=-2

Simplifing 7x+y=5 first

7x+y=5

y=-7x+5

Next, 7x+y=-2

7x+y=-2

y=-7x-2

Plugging in -7x+5 into y

-7x+5=-7x-2

-14x=-7

x=.5

Plugging .5 into y=-7x-2

y=-7(.5)-2

y=-3.5-2

y=-5.5

I used substitution if your couldn't tell

Answer:

Step-by-step explanation:

Very simple.

p - 5 = 19

So to take out the -5 on that side, you must also do the same thing to the other side. So adding 5 in one side of the equal sign would mean you have to do the same thing on the other side of the equal sign.

SO:

p-5 +5 = 19+5

p = 24
