Step-by-step explanation:
Answer:
- 11 / 15
Step-by-step explanation:
x = - 2
y = - 1 / 5
1 / 3 + x . z
= 1 / 3 + ( - 2 ) . ( - 1 / 5 )
= 1 / 3 + ( - 2 . - 1 ) / 5
= 1 / 3 + 2 / 5
1 / 3
= ( 1 / 3 ) x ( 5 / 5 )
= ( 1 x 5 ) / ( 3 x 5 )
= 5 / 15
2 / 5
= ( 2 / 5 ) x ( 3 / 3 )
= ( 2 x 3 ) / ( 5 x 3 )
= 6 / 15
1 / 3 + 2 / 5
= 5 / 15 + 6 / 15
= ( 5 + 6 ) / 15
= 11 / 15

Just remember the exterior angle is the sum of the 2 interior angles.
Answer:
f = 29
Step-by-step explanation:
First look at the angle inside the triangle that has no marker. You can determine this angle using the angle on the opposite side (112).
A straight line will equal 180. So this angle would equal 180 - 112 or 68.
Now you know two of the triangles angles.... 53 and 68.
A triangle's inside angles always add up to 180 degrees.
53 + 68 = 121
The angle that is 2f + 1 must equal 180 - 121 which is 59 degrees.
2f + 1 = 59
2f = 58
f = 29
The three angles inside the triangle are 53, 68 and 59

Answer:
Pizza 1: lenght(l)=16 and width(w)=4
Perimeter=40in.
Pizza 2: l=32 and w=2
Perimeter=68in.
Step-by-step explanation:
1. List down factors of 64.
64=1,2,4,8,16,32,64
2. Select the factors you'll be using to draw your rectangles. In this case I selected the factors 2,4,16 and 32 because area of rectangle=l×w. Therefore 2×32=64 and 4×16=64.
3. Draw your rectangles according to the measurements you chose. If the drawing is too big to fit the box you can simply use a scale. Such as 1 inch=4 inches on your drawing. For example, when drawing the length of the second Pizza which is 32in. you can simply draw a line of 8 inches.
4. After drawing your pizzas you niw have to find the Perimeter of both. Simply use the formula Perimeter of a rectangle=2(l+w)
Pizza 1: Perimeter=2(16+4)
=2×20
=40in.
Now do the same for Pizza 2 using its own lengjt and width. Hope this helped.

The length of a rectangle is 5 in longer than its width.
If the perimeter of the rectangle is 74 in, find its length and width.
Answers
Answer:
Length = 21
Width = 16
Step-by-step explanation:
We know that the formula for perimeter is:
P=2W+2L
And we also know that:
L=W+5
So then we put all that we know in the formula:
74=2W+2(W+5)
Now we expand the brackets and do some algebra:
74=4W+10 (-10)
64=4W (÷4)
16=W
Now that we know the width we can pop that into the length equation:
L=16+5
L=21

I need help on the whole assignmnet but particularly this question..
Answers
Answer:
1) 62.5
2) 50
3) 75
4) 100
Step-by-step explanation:
1)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*4=100[/tex] days, there will be [tex](1/2)^{4}=1/2^{4}=1/16[/tex] of it left.
So, [tex]1000/16=\boxed{62.5}[/tex].
2)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*3=75[/tex] days, there will be [tex](1/2)^{3}=1/2^{3}=1/8[/tex] of it left.
So, [tex]400/8=\boxed{50}[/tex]
3)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*2=50[/tex] days, there will be [tex](1/2)^2=1/2^{2}=1/4[/tex] of it left.
So, [tex]300/4=\boxed{75}[/tex].
4)
The only answer left is [tex]\boxed{100}[/tex] grams. You can solve it the same way you solved the previous steps.
