Answer:

-2a + 20b - 2c

Step-by-step explanation:

(6a + 5b + 4c) + (–6c + 15b) + (–8a) = 6a + 5b + 4c - 6c + 15b - 8a

= 6a - 8a + 5b + 15b + 4c - 6c

= -2a + 20b - 2c

Please help me find large & smaller angle

Dennis_Churaev [7]

If one angle is 9 times the other angle, and they're complementary, you can set up an equation.

90 = x + 9x

x is the smaller angle. When you solve for x, you get 9.

So, the large angle is 81°, and the smaller angle is 9°.

Hope this helped!! xx

Allison is rolling her hula hoop on the playground. The radius of her hula hoop is 35 \text{ cm}35 cm35, start text, space, c, m

scoray [572]

Answer: 880 cm

Step-by-step explanation:

Given: Radius of the hula hoop = 35 cm

Hula hoop is circular in shape

Then, Circumference = $2\pi r$ , where r = radius

Now , Circumference of hula hoop = $2\times \dfrac{22}{7}\times35=220\ cm$

Now , the distance the hula hoop rolls in 4 full rotations = 4 × (Circumference of hula hoop)

$= 4 \times 220=880\ cm$

Hence, the required distance = 880 cm

Laura babysat 8 nights during the month of July. She earned $22, $30, $35, $25, $25, $20, and $27 for seven nights. How much did

Svet_ta [14]

Answer:

$28

Step-by-step explanation:

Given:

data = [22,30,35,25,25,20,27]

For eight night, the new list is:

new_data = [22,30,35,25,25,20,27,x]

Mean = 26.50

Mean Formula:

$\displaystyle \large{m=\dfrac{x_1+x_2+x_3+...+x_n}{n} }$

Therefore:

$\displaystyle \large{26.50=\dfrac{22+30+35+25+25+20+27+x}{8}}$

Multiply both sides by 8:

$\displaystyle \large{26.50\cdot 8=\dfrac{22+30+35+25+25+20+27+x}{8} \cdot 8}\\\displaystyle \large{212=22+30+35+25+25+20+27+x}$

Solve for x:

$\displaystyle \large{212=22+30+35+25+25+20+27+x}\\\displaystyle \large{212=184+x}$

Subtract 184 both sides:

$\displaystyle \large{212-184=184+x-184}\\\displaystyle \large{28=x}$

Therefore, she will earn $28 in eighth night

The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.
