Answer:

1260

Step-by-step explanation:

Since we have to predict, we can use ratios to help us solve this.

12 said yes out of 72 randomly chosen, SO,

if 210 would say yes (goes to play), how many is total??

12 is to 72  AS  210 is to HOW MUCH (let it be x)??

<em>We can setup ratio, cross multiply, and solve for x:</em>

<em>\frac{12}{72}=\frac{210}{x}\\12x=210*72\\12x=15,120\\x=\frac{15,120}{12}\\x=1260</em>

<em />

<em>around 1260 students attend the school</em>

Answer:

1260 is the answer

Step-by-step explanation:

12 = 210

----   -----

72       x

= 12x=  15120

divide 15120 by 12 and you get:

x= 1260

. Shanice is making a garden. The area of the garden is 24 ft2. Use the following shape and information to find the base (6−4) a
crimeas [40]

Answer:

The base and height  of the garden are 4.60 ft and 5.60 ft.

Step-by-step explanation:

The area of the garden is, <em>A</em> = 24 ft².

The base height of the garden are:

base (<em>b</em>) = 6x - 4

height (<em>h</em>) = x + 3

Compute the value of <em>x</em> as follows:

A=\frac{1}{2}\times b \times h\\\\24=\frac{1}{2}\times (6x-4) \times (x+3)\\\\48=6x^{2}+18x-4x-12\\\\6x^{2}+14x-60=0\\\\3x^{2}+7x-30=0\\

The last equation is a quadratic equation.

Compute the roots of the quadratic equation as follows:

x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }\\x = \frac{ -14 \pm \sqrt{14^2 - 4(3)(-30)}}{ 2(3) }\\x = \frac{ -14 \pm \sqrt{556}}{ 6 }\\x = \frac{ -14 }{ 6 } \pm \frac{2\sqrt{139}\, }{ 6 }\\x = -\frac{ 7}{  3 } \pm \frac{ \sqrt{139}\, }{  3 }\\x = 1.59661\\x\approx 1.60

The value of base and height are:

\text{base}=6x-4=(6\times 1.60)-4=5.60\ \text{ft}\\\\\text{height}=x+3=1.60+3=4.60\ \text{ft}

Thus, the base and height  of the garden are 4.60 ft and 5.60 ft.

Name the smallest angle of ABC. The diagram is not to scale.
kirill [66]
The smallest angle would be angle C. The reason why is because angle C is opposite of the shortest side (AB). The smallest angle in a traingle is opposite of the shortest side.
