Answer:

q = 80

Step-by-step explanation:

Here, we want to get the value of w

Mathematically, we can obtain the cumulative frequency from the frequency tab

To do this, we have to sum up the frequencies at each point to get the cumulative at each point

We add the frequency above to the frequency below to get the value of the cumulative frequency at that point

We have it that;

we start with 10: as seen on the frequency column

then we proceed;

10 + 20 = 30

30 + 30 = 60

60 + 20 = 80

80 + 10 = 90

90 + 10 = 100

As we can see here, the value of q is 80

Answer:

Here,

<1 = 120° [linear pair]

<2 = 60° [Vertically Opposite Angles]

<3 = 90° [linear pair]

<4 = 90° [Vertically Opposite Angles]

<5 = 30° [Angle sum property of triangle]

<6 = 150° [linear pair of <5]

Answer:

7

Step-by-step explanation:

A number multiplied with a variable is considered a coefficient. In this case, the coefficient is 7 because it is multiplied by the variable m.

Answer:

7

Step-by-step explanation:

The coefficient is the number that comes before the variable- in this case, x.

6 would be the constant

Answer:

sin J = [tex]\frac{15}{29}[/tex]

cos J = [tex]\frac{21}{29}[/tex]

tan J = [tex]\frac{5}{7}[/tex]

x = 14.6

Step-by-step explanation:

1st pic:

1st, find the missing side lenght:

[tex]a^{2} = c^{2} - b^{2}[/tex]

[tex]a^{2} = 58^{2} - 42^{2}[/tex]

[tex]a^{2} = 3364 - 1764[/tex]

[tex]\sqrt{a^{2}} = \sqrt{1600}[/tex]

a = 40

sin = [tex]\frac{opposite}{hypothenuse}[/tex] ⇒ [tex]sin J = \frac{30}{58} = \frac{15}{29}[/tex]

cos = [tex]\frac{adjacent}{hypothenuse}[/tex] ⇒ [tex]cosJ = \frac{42}{58} = \frac{21}{29}[/tex]

tan = [tex]\frac{opposite}{adjacent}[/tex] ⇒[tex]tanJ = \frac{30}{42} = \frac{5}{7}[/tex]

2nd pic:

use sine:

sin = [tex]\frac{opposite}{hypothenuse}[/tex]  

sine 59 = [tex]\frac{x}{17}[/tex]

sine of 59 is 0.857:

0.857 = [tex]\frac{x}{17}[/tex]

multiply 17 on both sides:

0.857 x 17 = [tex]\frac{x}{17}[/tex] x 17

14.569 = x

round to the nearest tenth:

14.569 = 14.6

Answer: (2,-1)

Midpoint formula = ([tex]\frac{x1+x2}{2}[/tex] , [tex]\frac{y1+y2}{2}[/tex])

9 + (-5) / 2 = 2

3 + (-5) / 2 = -1

Answer:

[tex]\frac{1}{10x}[/tex]

Step-by-step explanation:

[tex]\frac{2x^{6} }{20x^{7} } = \frac{x^{6} }{10x^{7} } \\\\=\frac{1}{10x}[/tex]

Answer:

2 pounds of dried fruit

Step-by-step explanation:

James bought of a pound of dried cherries and of a pound of dried cranberries. How much dried fruit did he buy? [Write your answer in simplest form.]

The total amount of dried fruit that he bought is calculated as:

1 pound of dried cherries + 1 pound of dried cranberries

= 2 pounds of dried fruit

Therefore, the total amount of dried fruit that James bought is 2 pounds of dried fruit.

Answer:

The cost of producing 60 t-shirts is $495.

36 t-shirts will let the cost, C(x) = 303

Step-by-step explanation:

If we producing 60 t-shirts, then we plug in 60 for the x, which x represents t-shirts for the marching band.

C(x) = 8x + 15

C(x) = 8(60) + 15

C(x) = 480 + 15

C(x) = 495

If the cost of the t-shirts is 303, we plug in 303 for the cost,C(x).

C(x) = 8x + 15

303 = 8x + 15

288 = 8x

x = 36

3x2+30x+63=0

Step 2: Factor left side of equation.

3(x+3)(x+7)=0

Step 3: Set factors equal to 0.

x+3=0 or x+7=0

x=−3 or x=−7

Answer: x=-3 and x=-7

Answer:

5.460

Step-by-step explanation:

Answer:

6.24

Step-by-step explanation:

The formula for finding the area of a triangle is A = 1/2 b x h, (A meaning area, B meaning the base of the triangle, and H meaning the height of the triangle.)  Plug in the values for the formula and you get A = 1/2 (4.8) x (2.6)  Multiply 4.8 and 2.6 to get 12.48.  1/2 of 12.48 is 6.24, so that is the answer.  

Sorry if I'm wrong, but I hoped this helped!  :)

Answer:

x = 54°

Step-by-step explanation:

90° = 2x-18°

90° + 18° = 2x

108° = 2x

x = 54°

Answer:

x = 54

Step-by-step explanation:

The two angles added together equal 90 degrees because they are  complementary angles.

x - 18 + x = 90

Combine like terms

2x - 18 = 90

add 18 to both sides

2x = 108

Divide each side by 2

x = 54

Fill in for x

54 - 18 + 54 = 90

36 + 54 = 90

90 = 90

This proves that the answer is true.

Step-by-step explanation:

= 6x² - 11x - 10

= 6x² + 4x - 15x - 10

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

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

x = 5/2 & -2/3

Sarah is faster.

Step-by-step explanation:

Timmy travels 70 in 1 second.

Sarah travels 75 in 1 second.

The values of [tex]x[/tex] that solve the equation [tex]f(x) = g(x)[/tex] are 0, 0.256 and 2.285, respectively.

In this question we must look for all points where each curve intersects each other. By direct inspection on figure given, we conclude that [tex]f(x) = g(x)[/tex] happens in thrice: (i) [tex](x,y) = (0, 0)[/tex], (ii) [tex](x,y) = (0.256, 0.505)[/tex], (iii) [tex](x,y) = (2.285, 1.512)[/tex]

Hence, the values of [tex]x[/tex] that solve the equation [tex]f(x) = g(x)[/tex] are 0, 0.256 and 2.285, respectively.
