after school, maurice walks 1/3 mile to the park and then walks 1/2 mile to his house. how far does maurice walk from school to
sergeinik [125]
Let
x-----> distance school to the park
y-----> distance park to the house

we know that
x=1/3 mile
y=1/2 mile

[distance from school to the house]=x+y----> (1/3+1/2)
The common denominator is (3*2)---> 6
=(2*1+3*1)/(3*2)----> 5/6 mile

the answer is
5/6 miles

4. For a line whose slope is -3 and which passes through the point (5. - 2)
sergey [27]
For point slope form just plug in what is given so you have

m = -3
point (x₁, y₁): (5, -2)

y-(-2) = (-3)(x-(5))
y+2 = -3(x-5)

^for point slope form

for y-intercept form...just solve your point slope equation for y:

y+2 = -3(x-5)
y+2-2 = -3(x-5) -2
y = -3x+15 -2
y = -3x + 13

hope this helps :)

Sixty photos taken at a photo shoot are in black and white. If this represents 15 percent of the total number of photos taken, w
Art [367]

Answer:

D. 15×4/100×4 = 60/400

Step-by-step explanation:

First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.

Please solve with explanation.
Vesna [10]

Answer:

Area = 160 cm²

Perimeter = 55.31 cm

Step-by-step explanation:

Applying,

Area of the figure = area of the rectangle- area of the triangle

A = lw+bh/2............... Equation 1

From the question,

Given: l = 16 cm, w = 12 cm, h = 8cm, b = 8 cm

Substitute these values into equation 1

A = (16×12)-(8×8/2)

A = 192-32

A = 160 cm²

Perimeter P = /BC/+/CD/+/DE/+/EF/+/FG/+/GA/

Applying pythagoras theorem to get /FG/

FG² = GE²+EF²

FG² = 8²+8²

FG² = 64+64

FG² = 128

FG = √128

FG = 11.31 cm

Therefore,

P = 16+12+4+8+11.31+4

P = 55.31 cm
