Need math help worth 20 point helppppppp plzzzzz

Answer:

y = -2x - 2

Step-by-step explanation:

Given:

m = -2

Slope-intercept:

y - y1 = m(x - x1)

y + 8 = -2(x - 3)

y + 8 = -2x + 6

y = -2x - 2

Answer:

I can't see the rest of the answers, but I believe it is the first answer. Both triangles are congruent.

answer:

2,558

step-by-step explanation:

the formula for the volume of a cone is v=πr²h/3

with that let us 'fill in' the formula-

v=π*9.6²*26.5/3

v=2,557.51

then since you've asked us to round the answer to the nearest whole number that would be 2,558

good luck :)

i hope this helps

Answer:

zero = (-1,0)

Step-by-step explanation:

Since the slope is 3, you are going to take the given point and go back one space (behind the given point), continue to go up the lines and you should be given the point (0,-3),  then you keep this process going until you get your zero (x-axis meeting point) :)

Answer:

132 degrees

Step-by-step explanation:

the angles of measure 2 and 3 have to add up to 180 degrees (because that's the angle of a straight line, which 2 and 3 make together)

180-48=132

Answer:

Answer:

720 pounds

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Number of mangoes in a barrel = 400

Each mango weight = 1.8 pounds

So, we can calculate the total weight of mangoes by using following formula,

Total weight = Number of mangoes in a barrel × Each mango weight

By putting value, we get

Total weight = 400 × 1.8 pounds

= 720 pounds

Answer: Since this is the right triangle so

[tex]Sin B = \frac{AC}{AB} =\frac{AC}{6} \\=> AC = sin(20) * 6 = 5.478 = 5.48[/tex]

Apply Pythagorean theorem:

[tex]AC^{2} +CB^{2} =AB^{2} \\5.48^{2} +CB^{2} =6^{2}[/tex]

[tex]CB = \sqrt{6^{2} -5.48^{2} } = 2.44[/tex]

Answer:

1  1/3

Step-by-step explanation:

Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

8/6= 1.3333333333333 = 1

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (1) and multiply it by the original denominator (6). The result of that multiplication is then subtracted from the original numerator:

8 - (6 x 1) = 2

Step 3: Our mixed fraction

We've now simplified 8/6 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

1  2/6

Step 4: Simplifying our fraction

In this case, our fraction (2/6) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 2 and 6 is 2.

We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.

2/2 = 1

6/2 = 3

When we put that together, we can see that our complete answer is,

1  1/3

Answer:

Less than a right angle.

Step-by-step explanation:

If you really think about it, a right angle is 90 degrees, and from the looks of it, that angle shown is an acute angle. Acute angles are always smaller than a right angle, so your answer is less than a right angle. :)

Answer

The length is 11.5.

Step-by-step explanation:

Knowing to find the volume, you must use w,h,l, we simply need to switch up the formula. the new formula is L= V over hw = 948.75 over 11 x 7.5 = 11.5

Answer:

1) 21

2) 28

3) 13

Step-by-step explanation:

According to the word problem, a=7 and b=4.

Now, we just plug in the numbers.

14 + 7 = 21

7 ⋅ 4 = 28

5 ⋅ 4 - 7 = 13

ANYTIME YOU SEE TWO VARIABLES (LETTERS) TOGETHER, THAT MEANS MULTIPLY THEM.

AN EXAMPLE OF THIS IS NUMBER 2.

Answer:

(3,6)

Step-by-step explanation:

Y=X+3

Y=X2

X+3=2X

X-2X= -3

-x=-3

x=3

then Y=2X

Y=2×3

Y=6

Answer: 5 quintal = 500 kilogram

Step-by-step explanation:

Answer:

See a solution process below:

Step-by-step explanation:

The slope can be found by using the formula:  

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Where  m is the slope and ( x) and ( ) are the two points on the line.  

Substituting the values from the points in the problem gives:  

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }=\frac{-7-(-3)}{9-2}= \frac{-4}{7}=-\frac{4}{7}[/tex]

7x9=63/2=31.5

31.5x4= 126

7x7=49

126+49=175

The surface area of the pyramid would be 175cm^2

Answer:

26

Step-by-step explanation:

4x-2(x+y)=?

4*10-2(10-3)

40-2(7)

40-14

26

4x - 2 ( x + y ) = 4x - 2x - 2y

= 2x - 2y

= 2 ( x - y )

= 2 × ( 10 - (- 3) )

= 2 × 13

= 26

Step-by-step explanation:area of the flower bed = pie r square . 3.14 x 10 x 10

= 314.00m SQ

area of flower bed = pie r square

=3.14 x 8 x 8

= 200.96 m sq

side walk = incl area - excl area= 314 - 200.96 = 113.4m sq
