The answer is 108

you do it by doing 5+3+2=10
then do 360÷10=36 then 36x5=180 so there would be 180 squares then 36x2 180-72=108

Answer:

108

Step-by-step explanation:

We have a ratio problem

squares: triangles: circles

5 3 2

Multiply by x to keep the ratio the same

5x 3x 2x

The total of this is 360 because there are 360 shapes

5x+ 3x+ 2x = 360

Combine like terms

10x = 360

Divide by 10

10x/10 = 360/10

x = 36

squares: triangles: circles

5x 3x 2x

5*36 3*36 2*36

180 108 72

How many more square than circles

squares - circles

180 - 72

108

A cone has a diameter of 30 in. and a slant height of 17 in. What is the approximate volume of the cone?

Alex777 [14]

We need to find the height of the cylinder
pythagorean theorem
15 is the bottom leg (30/2=15)
17 is hypotonuse
b=height
15^2+b^2=17^2
225+b^2=289
minus 225 both sides
b^2=64
sqrt both sides b=8

Vcone=(1/3)hpir^2
d/2=r=30/2=15
h=8
V=(1/3)8pi15^2
V=(1/3)8pi225
V=8pi75
V=600pi
aprox pi=3.14159256
V=1884.955536 in^3

Somebody please gimme the answer ! It’s confusing..

torisob [31]

The equation for finding the area of a triangle is (bh)/2.
(The slash is a division sign)

So, with this equation, it would be (19*12)/2.

That would equal 114. So the answer is 114 ft squared.

According to industry sources, online banking is expected to take off in the near future. The projected number of households (in

Answer:

(a) The least-square regression line is: $y=4.662+2.709x$ .

(b) The number of households using online banking at the beginning of 2007 is 31.8.

Step-by-step explanation:

The general form of a least square regression line is:

$y=\alpha +\beta x$

Here,

y = dependent variable

x = independent variable

α = intercept

β = slope

(a)

The formula to compute intercept and slope is:

$\begin{aligned} \alpha &= \frac{\sum{Y} \cdot \sum{X^2} - \sum{X} \cdot \sum{XY} }{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} \\\beta &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} \end{aligned}$

The values of ∑X, ∑Y, ∑XY and ∑X² are computed in the table below.

Compute the value of intercept and slope as follows:

$\begin{aligned} \alpha &= \frac{\sum{Y} \cdot \sum{X^2} - \sum{X} \cdot \sum{XY} }{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 68.6 \cdot 55 - 15 \cdot 218.9}{ 6 \cdot 55 - 15^2} \approx 4.662 \\ \\\beta &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 6 \cdot 218.9 - 15 \cdot 68.6 }{ 6 \cdot 55 - \left( 15 \right)^2} \approx 2.709\end{aligned}$

The least-square regression line is:

$y=4.662+2.709x$

(b)

For the year 2007 the value of x is 10.

Compute the value of y for x = 10 as follows:

$y=4.662+2.709x$

$=4.662+(2.709\times10)\\=4.662+27.09\\=31.752\\\approx 31.8$

Thus, the number of households using online banking at the beginning of 2007 is 31.8.

DO NOT OVERLOOK THIS!!!!!!!!

zmey [24]

<h2>Answer:</h2>

Area = 2(1/2 × 5 × 5) + 20 × 10

= 2 × 12.5 + 200

= 25 + 200

= 225ft².
