Step-by-step explanation:

let father's age be f yr old and son age be s yr old

f = 5s -(1)

f + s = 60 -(2)

sub (1) into (2):

5s + s = 60

6s = 60

s = 10

f = 60 - 10 = 50

in 5 yr time, father age = 50 + 5 = 55

son age = 10 + 5 = 15

Graph the image of this figure after a dilation with a scale factor of 13 centered at the point (4, −2) .

Sonja [21]

Answer:

From the given triangle figure;

Labelled the triangle as A , B and C.

The coordinates of this triangle ABC are;

A = (1, 10) ,

B = (-2, 4)

C = (7, 4).

Given : Scale factor(k) = $\frac{1}{3}$ and centered at point (4, -2).

The rule of dilation with $k= \frac{1}{3}$ and center at point (4,-2) is:

$(x, y) \rightarrow (\frac{1}{3}(x-4)+4 , \frac{1}{3}(y+2)-2)$

$(x, y) \rightarrow (\frac{1}{3}x-\frac{4}{3}+4 , \frac{1}{3}y+\frac{2}{3}-2)$

or

$(x, y) \rightarrow (\frac{1}{3}x+\frac{8}{3} , \frac{1}{3}y-\frac{4}{3})$

then, the dilation of the given figure are;

$A(1, 10) \rightarrow (\frac{1}{3}\cdot 1+\frac{8}{3} , \frac{1}{3} \cdot 10-\frac{4}{3})$ = $(\frac{1}{3}+\frac{8}{3} , \frac{10}{3}-\frac{4}{3})$ = $(\frac{9}{3} , \frac{6}{3})$ = A'(3 , 2)

$B(-2, 4) \rightarrow (\frac{1}{3}\cdot -2+\frac{8}{3} , \frac{1}{3} \cdot 4-\frac{4}{3})$ = $(-\frac{2}{3}+\frac{8}{3} , \frac{4}{3}-\frac{4}{3})$ = $(\frac{6}{3} , \frac{0}{3})$ =B'(2 , 0)

$C(7, 4) \rightarrow (\frac{1}{3}\cdot 7+\frac{8}{3} , \frac{1}{3} \cdot 4-\frac{4}{3})$ = $(\frac{7}{3}+\frac{8}{3} , \frac{4}{3}-\frac{4}{3})$ = $(\frac{15}{3} , \frac{0}{3})$ = C'(5 , 0)

The coordinates of dilation images are:

A' = (3,2) , B' = (2, 0) and C' = (5, 0)

You can see the graph of the dilated image as shown below:

The 7 grade student at palm coast muddle school made some apple pies for a bake sale . the school cafeteria also donated 9 pies

Reil [10]

Answer:

The students baked 19 pies.

Step-by-step explanation:

Least total pieces of pies sold = 224

Number of pies donated by school cafeteria = 9

Number of pieces of pies donated by school cafeteria = 9×8 = 72

Number of pieces of pies baked = 224 - 72 = 152

Number of pies baked = 152 ÷ 8 = 192

A prom ticket at Smith high school is $120.Tom is going to save money for the ticket by walking his neighbor's dog for $15 per w

Ugo [173]

120 - 22 = 98. 98 / 15 = 6.533333. Because you want the minimum, and he can't get paid during 0.53333 of a week, Tom must walk the dog for a minimum of 7 weeks.
