some smart people here know the answer, plz? Thank you!

Answer:

Step-by-step explanation:

from how the sides are marked it is an equilateral triangle, to see it does not seem. assuming that it is equilateral it has 3 angles of 60 ° for which 4x - 20 = 60

4x - 20 = 60

4x = 80

x = 80 : 4

x = 20

-------------------

4 * 20 - 20 = 60°

Ah sorry I got it wrong, dear

she keeps 270

Step-by-step explanation:

have of 600 is 300 10 percent of 300 is 30

300-30 is 270

Answer: A multiple is a number that can be divided by another number a certain number of times without a remainder. A factor is one of two or more numbers that divides a given number without a remainder. Therefor, 50 could not be a multiple of 6.

Answer:

$42.60

Step-by-step explanation:

(6/100)×710

= $42.60

If a truck is 50% longer than the car, then its 1.5x.

200 * 1.5

= 300

So the truck is 300 inches

*50% of 200 is 100.

100+200=300* would be your answer.

Answer:

275 miles

Step-by-step explanation:

110/2 = 55 miles

you travel 55 miles an hour

multiply that by 5 to get your answer

equals 275 miles

Hope this is helpful.

Answer:

275 miles in 5 hours

Step-by-step explanation:

110/2 is 55. 55 is 1hour so multiply 55 times 5 and thats your answer.

Answer:

30a + 29b is the answer

We just need to add

Hii!

After 3.5 days, the height of the plant is 5.75 centimeters.

h = 0.5(3.5) + 4

h = 1.75 + 4

height = 5.75 cm after 3.5 days.

The height of the plant is 6.25 centimeters after 4.5 days.

6.25 = 0.5d + 4

6.25 - 4 = 0.5d - 4

2.25 = 0.5d

2.25/0.5 = 0.5d/0.5

4.5 = d

days = 4.5

Thus, the height of the plant is 6.25 centimeters after 4.5 days.

After 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The equation of the line is:

h = 0.5d + 4

After rewriting the function:

f(x) = 0.5x + 4

Plug x = 0

f(0) = 4 cm

f(1) = 4.5 cm

f(2) = 5 cm

f(3) = 5.5 cm

f(4) = 6 cm

f(5) = 6.5 cm

Plug x = 3.5 days

f(3.5) = 5.75 cm

Plug f(x) = 6.25

6.25 = 0.5x + 4

2.25 = 0.5x

x = 4.5 days

Thus, after 3.5 days, the height of the plant is 5.75 centimeters and the height of the plant is 6.25 centimeters after 4.5 days.

Answer:

15000 millimeters

750000 millimeters

Answer:

slope = 2 because it goes up by 2 and across 1

10 = 2(1)+b

10=2+b

-2   -2

b = 8

y intercept = 8

equation: y = 2x+8

yes it is proportional because it has a constant rate of change or slope

* means multiply

y = 2 * 7 + 7 = 14 + 7 = 21 -> (7,21)

y = 2 * 0 + 7 = 0 + 7 = 7 -> (0,7)

y = 2 * -5 + 7 = -10 + 7 = -3 -> (-5,-3)

Answer: In decimal the answer is 4.5 but if in fraction the answer is 4 1/2

Step-by-step explanation: First we have to divide 90 and 20 will give us 4.5 or 4 1/2

90 x 20 = 4.5 or 4 1/2

Answer:

-7/9

Step-by-step explanation:

Using the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 6-13)/(10-1)

    = -7/9

√44

2 Real Roots

Looking at the image attached, the discriminant is the value under the square root.

In the equation given:

a = 1

b = -8

c = 5

The discriminant is therefore:

√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44

√44 is a positive number. Because it is positive, there must be 2 real roots.

If it were negative, there would be 2 imaginary roots.

If it were zero, there would be 1 real root.

Answer:

6x+3+2x+8

8x+11x

Answer:

so slop int form is y=mx+b

so start off by distributing the -7 to the x and -3

so that leave you with y+4=-7x+21

get it all on the same side
