Ksivusya [100]3 years ago
6 0

Answer:

It will travel

33 \frac{1}{4}  \: miles

in 45 minutes.

Step-by-step explanation:

We can solve using proportions.

\frac{ 2\frac{1}{2} \: miles}{ 3\frac{1}{3} \: minutes}  =  \frac{x}{45 \: minutes} \\  \\  \frac{ 3\frac{1}{3} x}{ 3\frac{1}{3} }  =   \frac{ 112\frac{1}{2} }{ 3\frac{1}{3} }    \\  \\  x = 33\frac{3}{4}

A rectangular block of ice measures 42 cm × 25 cm × 18 cm. Calculate its total
kirill115 [55]

Answer: T.S.A = 4512cm^2

volume = 18900cm^3

weight = 17.01 kg

Step-by-step explanation:

T.S.A of cuboid = 2(lb+bh+lh)

= 2(42x25 + 25x18 + 42x18)

=2(1050 + 450 + 756)

=2 x 2256

= 4512cm^2

to find weight, we've to find the volume of the ice cube

therefore, volume of a cuboid = lbh

=42 x 25 x 28

=18900cm^3

weight of 1cm^3 of ice = 0.9grams

therefore weight of 18900cm^3 of ice = 18900 x 0.9

= 17010 grams = 17.01kg

Hope it helped u,

Solve for x:<br> x^2=a<br><br> If a&lt;0, then <br> If a=0, then<br> If a&gt;0, then
Anastaziya [24]

if a > 0, there are two possible solutions:

x^{2} = a\\\sqrt{x^{2} } = \sqrt{a} \\

the square root of a square is the base in absolute value bars

|x| = \sqrt{a}

x = -\sqrt{a} ; x = \sqrt{a}

if a = 0, that means x = 0. anything multiplied by 0 is 0

if a < 0, there are no solutions because anything squared has to be positive

Find the restricted values of x. -1/8x-2
Dmitry [639]

x = \frac{1}{4} is the restricted value

the denominator of the fraction cannot be zero as this would make it undefined.

Equating the denominator to zero and solving gives the value that x cannot be

solve : 8x - 2 = 0 → 8x = 2 → x = \frac{1}{4}

Graph the function defined by f(x)=|-x+8|
densk [106]

Answer:

Option 3.

Step-by-step explanation:

In this question we have to draw a graph f(x) = |-x+8|

Its a modified form of a graph f(x) = |-x| which starts from origin, having two perpendicular lines in quadrant 1 and 2.

Then f(x) = |-x| is shifted 8 units right on the x-a xis. therefore the modified form becomes f(x) = |-x+8| as shown in the option number 3.

Option 3 is the correct answer.
