Well, we can simply divide 10 and 1/2 by 7, that's how many "yards" time 7 goes into 10 and 1/2.

\bf \cfrac{\quad10\frac{1}{2} \quad }{7}\implies \cfrac{\quad \frac{10\cdot 2+1}{2}\quad }{\frac{7}{1}}\implies \cfrac{\quad \frac{21}{2}\quad }{\frac{7}{1}}\implies \cfrac{21}{2}\cdot \cfrac{1}{7}\implies \cfrac{3}{2}\cdot \cfrac{1}{1}
\\\\\\
\cfrac{3}{2}\implies \stackrel{yards}{1\frac{1}{2}}

Andrews [41]

Answer:

Step-by-step explanation:

let f(x)=ab^x

when x=1,f(x)=6

6=ab

when x=2,f(x)=18

18=ab^2

divide

\frac{ab^2}{ab}=\frac{18}{6}\\b=3\\ab=6\\3a=6\\a=2\\f(x)=2(3)^x

Choose the correct description of the graph of the compound inequality: (5 points)
skad [1K]

Answer:

D

Step-by-step explanation:

Firstly,  

≤  or  ≥  means closed circle, and

<   or >  means open circle

Now, let's solve the compound inequality:

x - 1 ≤ 7

x ≤ 8

and

2x ≥ 22

x ≥ 11

This solution means "everything left of 8 (inclusive and closed circle)" and "everything right of 11 (inclusive and closed circle)"

Looking at the choices, D is right.

Galina is finding the area of triangle RST. To do so, she follows the steps in the table.
vladimir1956 [14]

1 step: to draw a rectangle around triangle RST, you should

  • draw points A(-1,-1), B(-1,3) and C(2,3);
  • connect points A, B, C and T consecutively.

2 step: rectangle ABCT has length AB=4 units and width BC=3 units. Then

A_{ABCT}=4\cdot 3=12 sq. un.

3 step:

A_{\triangle ART}=\dfrac{1}{2}AR\cdot AT=\dfrac{1}{2}\cdot 2\cdot 3=3 sq. un.

A_{\triangle BRS}=\dfrac{1}{2}BR\cdot BS=\dfrac{1}{2}\cdot 2\cdot 2=2 sq. un.

A_{\triangle SCT}=\dfrac{1}{2}CS\cdot CT=\dfrac{1}{2}\cdot 1\cdot 4=2 sq. un.

4 step:

A_{\triangle RST}=A_{ABCT}-A_{\triangle ART}-A_{\triangle BRS}-A_{\triangle SCT}=12-3-2-2=5 sq. un.

Answer: in step two you write dimensions of rectangle ABCT: length 4 units and width 3 units. Correct choice is B.
