51. (08.02 MC) Box A has a volume of 48 cubic meters. Box B is similar to box A. To create Box B, Box A's dimensions were double
Vanyuwa [196]

Answer:

384 m³

Step-by-step explanation:

Let the dimension of box a be l,b, and h.

ATQ,

lbh = 48 .....(1)

If we double the dimension of box A, we get box B whose new dimensions will be 2l,2b and 2h.

Let V be the volume of box B.

V = (2l)(2b)(2h)

V = 8(lbh)

= 8(48) [from equation (1)]

= 384 m³

Hence, the volume of the box B is 384 m³.

Find the surface area of the regular pyramid.
spayn [35]

Answer:

Answer = 93.6

Step-by-step explanation:

frist multipy 9 x 13 to get 117 than divided it by 2 = 58.5, than times it by 3 since there is three sides.

(58.5 x 3 is 175.5)      

Than for the base multipy 7.8 x 9 = 70.2, but since its a tri, divided it by 2 = 35.1.

Add 58.5 and 35.1 to get 93.6

Scientific Notation: 3.45 x 10^5

E Notation: 3.45e5

= 9.26 × 1010

(scientific notation)

= 9.26e10

(scientific e notation)

= 92.6 × 109

(engineering notation)

(billion; prefix giga- (G))

its probably: 9.26 × 1010 as the question asks for scientific notation

Step-by-step explanation:

somewhere between those lines, good luck!

Barry is trying to calculate the distance between point E(3, 1) and point F(4, 7). Which of the following expressions will he us
Alex777 [14]

Answer:

Option (1) is correct.

Barry uses the expression " square root of the quantity of 7 minus 1 all squared plus 4 minus 3 all squared " to find the distance between point E(3, 1) and point F(4, 7).

Step-by-step explanation:

Given : Barry is trying to calculate the distance between point E(3, 1) and point F(4, 7).

Distance between two points can be calculate using distance formula,

Distance formula states given two points P(a,b) and Q(c,d)  the distance between P and Q can be calculated using the given expression ,

D=\sqrt{(c-a)^2+(d-b)^2}

Thus,  distance between point E(3, 1) and point F(4, 7) can be calculate using above formula as ,

Here, a= 3 , b= 1 , c = 4 and d = 7

D=\sqrt{(c-a)^2+(d-b)^2}

Substitute above values, we get,

D=\sqrt{(4-3)^2+(7-1)^2}

D=\sqrt{(1)^2+(6)^2}

D=\sqrt{37}

Thus, Barry uses the expression " square root of the quantity of 7 minus 1 all squared plus 4 minus 3 all squared " to find the distance between point E(3, 1) and point F(4, 7).

Thus, Option (1) is correct.

Which best describes the range of the function f(x)=2/3(6)x after it has been reflected over the x axis
shtirl [24]
The range is all real numbers.

The function given simplifies to just f(x) = 4x.

This is just a straight line that is increasing from left to right. If we reflect the line over the x-axis, it is still a line that goes on forever in each direction.

Therefore, the range will be all real numbers.
