Hi there! :)

Answer:

SA = 124 cm².

V = 72 cm³

Step-by-step explanation:

Volume of a rectangular prism: V = l × w × h

Given:

l = 4 cm

w = 9 cm

h = 2 cm

V = 4 × 9 × 2

V = 36 × 2

V = 72 cm³

Surface area: SA = 2(wl + hl + hw)

SA = 2((4 · 9) + (2 · 4) + (9 · 2))

SA = 2(36 + 8 + 18)

SA = 2(62)

SA = 124 cm².

Hope this helped you!

When the number is reduced by 15% , the answer is 6154 . What is the original number ?
Vesna [10]

Let's assume the number as x .

15% of x = \dfrac{x \times 15}{100}

→ \dfrac{3x}{20}

So after reducing 15% the number will be 6154 .

→ x - 3x/20 = 6154

→ 17x/20 = 6154

→ 17x = 6154 × 20

→ 17x = 123080

→ x = 123080/17

  • → x = 7240

So the number is 7240

What are the coordinates of the point on the directed line segment from (-8, -10)(−8,−10) to (6, -6)(6,−6) that partitions the s
frez [133]

Answer:

(2.5, -7)

Step-by-step explanation:

Given:

Two end points of a line segment are given as:

(-8, -10) and (6, -6)

The ratio of partition is 3 : 1.

Let the line segment be AB with A(-8, -10) and B(6, -6). Let point P(x,y) divide the line segment AB in the ratio 3 : 1.

In order to find the point P, we use section formula which is given as:

(x,y)=(\frac{nx_1+mx_2}{m+n},\frac{ny_1+my_2}{m+n})

Where, (x_1,y_1)\ and\ (x_2,y_2) are end points of line segment AB divided in the ratio m : n by the point (x, y).

Now, plug in the given values and solve for the coordinates of P. This gives,

P(x,y)=(\frac{1\times -8+3\times 6}{3+1},\frac{1\times -10+3\times -6}{3+1})\\\\P(x,y)=(\frac{-8+18}{4},\frac{-10-18}{4})\\\\P(x,y)=(\frac{10}{4},\frac{-28}{4})\\\\P(x,y)=(2.5,-7)

Therefore, the coordinates of the point on the directed line segment from (-8, -10) to (6,−6) that partitions the segment into a ratio of 3 to 1 is (2.5, -7).
