I will assume that A = 72 yd^2 is the area of the rhoumbus.

The formula of the area is diagona 1 * diagonal 2 / 2

Then d1*d2 / 2 = 72

d2 = 72*2/d1 = 72*2/16 = 9 yd

Area of the rhombus:
A =  d 1 · d 2 / 2
72 = 16 · d 2  / 2
72 = 8 · d 2
d 2 = 72 : 8
Answer: d 2 = 9 yd

Amelia is taking a road trip. She drove 250 miles the first day. If 250 is 40% of her total distance, how many miles is her road
MakcuM [25]

Answer: 625 miles

Step-by-step explanation:

100-40=60

so she has 60% for her distance so lets munis 40 from it and add 250 to 250

250+250=500

60-40=20

20 is half of 40 so whats half of 250? its 125

so she drove 625 miles for her road trip 2 and 1/2 a day

tammy typed 40 pages of a report on Monday and 3/8 of the report on Tuesday. She completed the remaining 1/3 of the report on We
sergeinik [125]

Answer:

Step-by-step explanation:

R = report length

R = 40 + (3/8)R + (1/3)R

3/8 = 3*3/8*3 = 9/24

1/3 = 8*1 / 3*8 = 8/34

R = 40 + (9/24)R + (8/24)R

R = 40 + (17/24)R                         Subtract 17/24 from the left

R-17/24 R = 40

7/24 R = 40                                  Multiply both sides by 24

7R = 40 * 24

7R = 960                                       Divide by 7

R  = 960/7

R = 137.1 which breaks the rounding rule and becomes 138 because something has to be typed on page 138

Which value of y would make OP ll LN? A 16 B 24 C 32 D 36
Andreyy89

see the attached figure to better understand the problem

we know that

if OP ll LN

then

by proportion

\frac{MO}{ML} =\frac{MP}{MN}

we have that

MO=28\ units \\ML=28+14=42\ units\\MP=y\ units\\MN=(y+18)\ units

substitute

\frac{28}{42} =\frac{y}{(y+18)}\\ \\28(y+18)=42y \\ \\42y-28y=28*18 \\ \\14y=504 \\ \\y=36\ units

therefore

<u>the answer is</u>

The value of y is 36\ units
