Answer:

116

Step-by-step explanation:

so to find angle bcs we need to find x and to find x we need to create an equation. 160= angle scd +anglebcs so we do 180=3x+17+12x+8 and solve for x

160=3x+17+12x+8

step 1 combine like terms

160=15x+25

step 2 subtract 25 from each side

135=15x

step 3 divide each side by 15

9=x

then we plug in 9 to 12x+8 and get 116

Answer:

1 3/10

Step-by-step explanation:

3 7/10 - 2 2/5 =

3 7/10 - 2 4/10 =

1 3/10

Answer:

1 3/10

Step-by-step explanation:

Change the denominator of 2 2/5 to 10 to match denominators by multiplying 2 (numerator and denominator)

New equation: 3 7/10 - 2 4/10 = 1 3/10

Total cost is:

Answer:

✔ y = –4x + 5

✔ y = –2x + 3

Step-by-step explanation:

We can write -

The general equation of a straight line in slope intercept form -

y = mx + c

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of lines are -

We have the given system of equations as -

y - 5 = - 4x

3y - 9 = - 6x

The given system of equations is -

y - 5 = - 4x

3y - 9 = - 6x

Now -

y - 5 = - 4x

y = - 4x + 5

and

3y - 9 = - 6x

3y = - 6x + 9

y = (-6/3)x + (9/3)

y = - 2x + 3

So, we can write -

The slope-intercept form of the first equation is y = - 4x + 5.

The slope intercept form of the second equation is y = - 2x + 3.

Therefore, we can write -

Answer:

Translation (x, y) = (x - 2, y + 5)

(x, y) = (x - 2, y + 5)

(-3, 5) = (-3 - 2, 5 + 5)

(-3, 5) = (-5, 10)

So this means that point A' (-5, 10) is your translation of point A (-3, 5) .

Now let us look at the reflection. It says to reflect across the y = 4. Basically you will draw a horizontal straight line on 4. Count how many units is point A (-3, 5) is. Then do it on the other side of the line. Point A' (-3, 3) is reflected across y = 4 of point A (-3, 5).

Hope this helps, thank you !!

Answer:

35 minutes

Step-by-step explanation:

Given that:

Trista:

Average word type per hour = 2400 words /hr

For Trista to type her 1400 word research paper ;

It will take 'h' hour

If

2400 words = 1 hour

1400 words = h

Cross multiply :

2400h = 1400

h = 1400 / 2400

h = 0.5833333 hr

To minutes, it will take :

0.5833333 * 60 = 35 minutes

Hence, it will take Trista 35 minutes or 0.5833333 to type her 1400 words research paper.

Answer: no

Step-by-step explanation:

Answer: 4°F

Step-by-step explanation:

From the question, we are informed that temperature at 5:30 a.m was –4°F and that eight hours later, at 2:30 p.m, the temperature is the opposite of –4°F.

The temperature at 2:30 will be 4°F since the opposite of -4 is +4. Also since there's an interval of 8 hours, it's likely that the temperature increased by 1° for every hour. In 8 hours, it'll have increased by 8°, therefore the temperature will then be:

= -4 + 8

= 4°F

Answer:

(x-10)(x²+10x+100)

Step-by-step explanation:

Given the expression

X^3 - 100

This ca also be expressed as;

X^3 - 100 = X³ - 10³

a³-b³ = (a-b)(a²+b²+ab)

Substitute a = x and b = 10

X³ - 10³ = (x-10)(x²+10²+10x)

X³ - 10³ = (x-10)(x²+10x+100)

Hence the factored form is (x-10)(x²+10x+100)

-x=6+2y

2y=-x-6

y= -x/2 -3

Answer: a) 25%

b) 75% Chebyshev interval around the sample mean=(6,18)

Step-by-step explanation:

Given: Sample mean: [tex]\overline{x}=12[/tex]

Sample standard deviation: s= 3

a) Coefficient of variation = [tex]\dfrac{s}{\overline{x}}\times100[/tex]

[tex]\\\\=\dfrac{3}{12}\times100\%=\dfrac{100\%}{4}\\\\=25\%[/tex]

b) According to the Chebychev's theorem,

75% of the population lies within 2 standard deviations from the sample mean.

i.e. 75% Chebyshev interval around the sample mean. = [tex](\overline{x}-2s,\ \overline{x}+2s)[/tex]

[tex]=(12-2(3),\ 12+2(3))\\\\=(6, 18)[/tex]

Hence, the 75% Chebyshev interval around the sample mean=(6,18)

x=2 y=1 x+y= 2+1=3 3 is the value of x+y

Step-by-step explanation:

Answer:

X=2, Y=1

X+Y=3

Step-by-step explanation:

-6x+12=0. first subtract 12 from each side

-6x=-12 now divide both sides by -6

X=2

4y+5=9. subtract 5 from each side

4y=4 divide both sides by 4

Y=1
