Mathematics
1 answer:
jeka57 [31]2 years ago
4 0

Answer:

a) height =14in

b) height =27cm

Step-by-step explanation:

<h3>Greetings !</h3>

a)

v =  \frac{l \times w \times h}{3}

where,

  • v=448in³
  • w=12in
  • l=8in

Substitute these values and solve for h.

h = 3 \frac{v}{lw}  \\ h = 3. \frac{448}{8.12}  = 14

b)

v =  \frac{1}{3} ah

where, a=area of the base

  • h= height

plug in the given values and solve for h

v =  \frac{1}{3} ah \\ 3v = ah \\ h =  \frac{3v}{a}  \\ h =  \frac{3(270)}{30}  \\ h = 27cm

All zeros of polynomial function 3x^4 +14x^2 -5
Marizza181 [45]

Answer:

Correct answer:  x₁ = 1 / √3 = √3 / 3  or  x₂ = - 1 / √3 = - √3 / 3

Step-by-step explanation:

Given:

3 x⁴ + 14 x² - 5 = 0   biquadratic equation

this equation is solved by a shift  x² = t and get:

3 t² + 14 t - 5 = 0

t₁₂ = (-14 ± √14² - 4 · 3 · 5) / 2 · 3 = (-14 ± √196 + 60) / 6

t₁₂ = (-14 ± √256) / 6 = (-14 ± 16) / 6

t₁ = -5   or  t₂ = 1 / 3

the solution t₁ = -5 is not accepted because it cannot be x² = -5

we accepted  t₂ = 1 / 3

x² =  1 / 3  ⇒  

x₁ = 1 / √3 = √3 / 3  or  x₂ = - 1 / √3 = - √3 / 3

The test score for a class are shown. What is the average test score? 79,80,92,92,81,100,88,98,71,100,91,90
Oksanka [162]

Answer:

The average score is equal to 88.5

Step-by-step explanation:

we know that

An average test score is the sum of all the scores on an assessment divided by the number of test-takers.

so

The sum is equal to

Sum=[79+80+92+92+81+100+88+98+71+100+91+90]=1,062

The number of test-takers is n=12

The average score is equal to

\frac{S}{n}

substitute

\frac{1,062}{12}=88.5

A wheel has a radius of 28 cm. If it does 50 revolutions, what distance will it travel?
LuckyWell [14K]

Answer:

87.96 meters to the nearest cm.

Step-by-step explanation:

First find the circumference of the wheel

= 2 π r

= 2 π * 28

= 175.929 cm.

So one revolution is  equivalent to travelling 175.929 cm.

50 revolutions = 175.929 * 50

= 8796.46 cm.

= 8796.46  / 100

= 87.96 m (answer).
