Three small squares are drawn inside a larger square as shown. What is the length of the line marked with a question mark?
Answer:
19
Step-by-step explanation:
let the smallest square be A, medium square is B and the largest is C ;
as the length side of the main square is 28, we can find that,
A= 28-22 = 6
C= 28-15 = 13
So to find B,
A+B+C = 28
B = 28-A-C
B = 28-6-13 = 9
So the line with questioned mark is,
28-9 = 19

Can you help me with this question?
While Jackie was in Hawaii, she would dive for shells. One afternoon she dove −7.8 feet. Her next two dives were each 2 1/8 feet deeper than the dive before it. What were the depths of her second and third dives?
Dive 2: ? ft
Dive 3: ? ft
Answer:
Dive 2: -9 37/40 feet
Dive 3: -12 1/20 feet
Step-by-step explanation:
To solve this, we subtract 2 1/8 from -7.8 twice. First, convert -7.8 to a mixed number, that gets us -7 8/10. Now, we find the LCM of 8 and 10. That is 40. Now, we multiply 1/8 by 5/5 to get 5/40. Now, we multiply 8/10 by 4/4 to get 32/40. Now, we subtract 2 5/40 from -7 32/40. This gets us -9 37/40. That means Dive 2 was -9 37/40 feet. Now, we subtract 2 5/40 from -9 37/40. That gets us -12 2/40. We can simplify that to -12 1/20. That means Dive 3 was -12 1/20 feet.

What is the net force for this free body diagram below?
The figure below is made up of two rectangular prisms.
3 m
7 m
10 m
4 m 1 m
Find the volume of the entire figure by adding the volumes of the separate figures.
Volume = 120 +
cubic meters
Answer:
Total Volume = 190 m³Step-by-step explanation:
Volume of the entire figure = L (Area 1 + Area 2)
where L = 10 m
Area 1 (blue prism) = 4 x 3 = 12 m²
Area 2 (brown prism = 1 x 7 = 7 m²
plugin values into the formula:
Volume of the entire figure = L (Area 1 + Area 2)
= 10 (12 + 7)
= 120 m³ + 70 m³
= 190 m³

Mr Jones has 160 animals on his farm of these animals 20% of cows 30% of gold 10% are horses and the rest are chickens how many chickens are there
Answer:
64
Step-by-step explanation:
32 cows . 48 gold? 16 horses
32+48+16 = 96
160-96 = 64
Answer:
There are 64 chickens
Step-by-step explanation:
20% of 160 is 32 30% of 160 is 48 and 10% of 160 is 16. So 32 + 48 + 16=96.
160-96 = 64

a music store sells a used guitar for $120. This is $25 more than 1/2 the cost of a new guitar of the same brand. what is the cost of a new guitar?
Answer:
$190.
Step-by-step explanation:
We can write the equation 120=25+1/2n where n is the cost of a new guitar. First, we subtract 25 from both sides to get 95=1/2n. Then, we multiply both sides by 2 to get 190=n. Therefore, the cost of a new guitar is $190.

All of the following expressions are equivalent, except ______.
x - 7
7 + (-x)
-x + 7
7 - x
Answer:
x - 7
Step-by-step explanation:
Let's let x = 4 and see which one would be different
x - 7 = 4 - 7 = -3
7 + (-x) = 7 + -4 = 3
-x + 7 = -4 + 7 = 3
7 - x = 7 - 4 =3
As you can see, the top answer would be negative while all the rest are positive. This is because, in that case, the negative sign was attached to the 7 instead of the x.
Answer:
x - 7
