Answer:

Step-by-step explanation:

(A).Two corresponding sides of the given figures will be,

AB and DE

BC and EF

Similarly one pair of corresponding points will be,

A and D.

(B). Since large figure has been scaled to the smaller image,

Scale factor = $\frac{\text{Side of the image}}{\text{Side of the actual figure}}$

= $\frac{\text{AB}}{\text{DE}}$

= $\frac{0.5}{2}$

= 0.25

Therefore, scale factor will be 0.25.

18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented

makvit [3.9K]

Answer:

The cost of the green fees for each person was $16

Step-by-step explanation:

Let

x -----> the cost of the green fees for each person

we know that

The total cost of the green fees plus the green fees for each person must be equal to $76

so

The linear equation that represent this problem is

$76=4x+2(6)$

Solve for x

Subtract 12 both sides

$76-12=4x+12-12$

$64=4x$

$16=x$

Rewrite

$x=16$

therefore

The cost of the green fees for each person was $16

Find the cube roots of 27(cos 330Á + i sin 330Á). Please help c:

Mashcka [7]

Use formula
$e^{ix}=\cos{x}+\sin{x}$

$\sqrt[3]{27(\cos{330^o}+i\sin{330^o})} 
\\\sqrt[3]{27e^{i330^o} }
\\ \sqrt[3]{27} \sqrt[3]{e^{i330^o}} 
\\ \sqrt[3]{3^3} \sqrt[3]{e^{i110^o\times 3}} 
\\ \sqrt[3]{3^3} \sqrt[3]{(e^{i110^o})^ 3}} 
\\ 3e^{i110^o}
\\3(\cos{110^o}+i\sin{110^o})$

Since $330^o=360^o+330^o=690^o
$ and $330^o=2\times 360^o+330^o=1050^o$ there are two more solutions:
1. $3(\cos{230^o}+i\sin{230^o})$
2. $3(\cos{350^o}+i\sin{350^o})$

Serena estimates that she can paint 60 square feet of wall space every half -hour .Write a equations for the relationship with t

lina2011 [118]

Answer: So, the relationship with i hours as the indecent variables would be $y=120i$

Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Step-by-step explanation:

Since we have given that

Area that she can paint = 60 square feet

Time taken = half hour = 30 minutes = 0.5 hours

Using "Unitary method, we get that

In 0.5 hours, she can paint = 60 square feet

In 1 hour, she can paint = $\dfrac{60}{0.5}=120\ sq.\ feet$

In i hours, she can paint = $120\times i\ sq.\ feet=120i\ sq.\ feet$

Let the total area she can paint be 'y'.

So, the relationship with i hours as the indecent variables would be

$y=120i$

Now, Can Serena paint 400 square feet of wall space i. 3.5 hours

We put y = 400 and i = 3.5 hours to check whether it is equal or not.

$400= 120\times 3.5\\\\400\neq 420$

Hence, Serena can't paint 400 square feet of wall space of wall space in 3.5 hours.

Given the similarity statement ΔDEF ∼ ΔXYZ, which side corresponds with ED¯¯¯¯¯¯¯¯? Question 2 options: A) EF¯¯¯¯¯¯¯¯ B) ZY¯¯¯¯¯

avanturin [10]

Answer:

Option C.

Step-by-step explanation:

The given similarity statement is

$\Delta DE F\sim \Delta XYZ$

We need to find the side which is corresponds with ED.

According to the given similarity statement the pairs of corresponding sides are:

$DE\text{ and }XY\Rightarrow ED\text{ and }YX$

$EF\text{ and }YZ\Rightarrow FE\text{ and }ZY$

$DF\text{ and }XZ\Rightarrow FD\text{ and }ZX$

Since, YX is corresponds with ED, therefore, the correct option is C.
