(0.9) *(1.5 +5.8)

lisov135 [29]

(0.9)* (1.5+5.8)
First, Add the values to the right. You get (0.9) * (7.3)
Multiply 9 and 73 to get 730 -73, which is 700-43, 660 - 3, which is 657.
Divide by 100 by moving the decimal point to get 6.57 as your final answer.

Hope that helped!

the volume of a rectangular pyramid is 1.32 cubic inches. the height of the pyramid is 1.1 inches and the length of the base is

worty [1.4K]

Work:

V = l × w × h

1.32 = 1.2 × w × 1.1

1.32 = 1.32 × w

1.32 ÷ 1.32 = 1

Answer:

1 inch = width

given directed line segment AB find the coordinates of p such that the ratio of ap to pb is 2:1 plot point p

murzikaleks [220]

Answer:

$P(\frac{10}{3}, \frac{-2}{3})$

Step-by-step explanation:

The question is incomplete; However

$A = (-2, -4)$

$B = (6, 1)$

Required

Determine coordinates of P

When line segment is divided in ratios, the following formula calculates the coordinates;

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

In this case;

$m:n = 2:1$

$(x_1,y_1) = (-2, -4)$

$(x_2,y_2) = (6, 1)$

So, the coordinates of P is calculated as thus

$P(x,y) = \{\frac{2 * 6 + 1 * (-2)}{2+1}, \frac{2 * 1 + 1 * (-4)}{2+1}\}$

$P(x,y) = \{\frac{12 -2}{3}, \frac{2 -4}{3}\}$

$P(x,y) = \{\frac{10}{3}, \frac{-2}{3}\}$

Hence, the coordinates of P is

$P(\frac{10}{3}, \frac{-2}{3})$

Calculate the area of the trapezoid.<br> 38 ft<br> 8.5 ft<br> 19 ft

Mila [183]

Answer:

522.5

Step-by-step explanation:

you need to show me the picture, or point out which is the height, which are the bases.

I am supposed 38 is the height

8.5 & 19 are the bases.

the formula for calculating the are of the trapezoid is:

(8.5+19)*38 /2 =522.5
