A triangular parcel of land has side lengths of 100, 580, and 600 feet. Approximate the area of the land. Round your answer to the nearest foot.
Answer:
28800 square feet
Step-by-step explanation:
We solve this using the Heron's formula
Area of a Triangle = √s(s - a)(s - b)(s - c)
s = a + b + c/2
s = 100 + 580 + 600/2 = 640
Area of the land(Triangle) = √640 × (640 - 100)(640 - 580)(640 - 600)
= √640 × (540) ×( 60) × (40)
= √(829440000)
= 28800 square feet
Therefore, the approximate the area of the land is 28800 square feet.

Hope it is helpful....8. At a winery 15 people are hired to pick grapes. They pick 15 tons of grapes, which yield 1200 to 1300 gallons of wine ( 1 ton = 2000 pounds). What is the yield percent for grapes to produce wine? ( Use 1250 gallons in calculations)
Answer:
290.4 %
Step-by-step explanation:
Since 15 tons of grapes are picked and 1 ton = 2000 pounds, then 15 tons = 15 × 1 ton = 15 × 2000 lb = 30000 lb which is the mass of the grapes.
Since 1200 to 1300 gallons of wine are produced and we are to use 1250 gallons in calculations, since the density of wine, ρ = 8.262 lb/gallon, and ρ = mass of wine, m'/volume of wine, v = m/v
ρ = m/v
So, making m subject of the formula, we have
m = ρv
substituting the values of the variables into the equation, we have
m = 8.262 lb/gal × 1250 gal = 10327.5 lb
So, the yield percent for grapes to produce wine = mass of grapes/mass of wine × 100 %
= 30000 lb/10327.5 lb × 100 %
= 2.904 × 100 %
= 290.4 %
So, the yield percent for grapes to produce wine is 290.4 %
Witch statement about a quadrilateral is true 1. A rhombus has exactly one pair of parallel sides. 2. A trapezoid has two pairs of parallel sides. 3. All rectangle are squares. 4. Some rhombus have four right angles
Answer:
Statement 4 is true.
Step-by-step explanation:
- Statement 1 is false because a rhombus has 4 equal sides with 2 pairs being parallel to each other.
- Statement 2 is false because a trapezoid usually has only 2 sides that are parallel while the other 2 are not parallel. Thus it has only a pair of parallel sides.
- A square must have all 4 sides equal. But rectangles don't have all 4 sides equal and so the statement is false.
- Rhombus has all 4 sides equal and where it has all interior angles as right angles, it is called a square. Thus, some rhombus have all 4 interior angles as right angles.
Sam is 34 years younger than Ashton. 4 years ago, Ashton's age was 3 times Sam's age. How old is Sam now?
Answer:
21years old
Step-by-step explanation:
Let Sam's age be x
Let Ashton present age be y
If Sam is 34 years younger than Ashton then;
x = y - 34 .... 1
If by 4 years ago, Ashton's age was 3 times Sam's age then;
Sam = x - 4
Ashton = y - 4
y-4 = 3(x-4)
y-4 = 3x - 12 ....2
Substitute 1 into 2;
y-4 = 3(y-34)-12
y-4 = 3y-102-12
y-4 = 3y - 114
y-3y = -114 + 4
-2y = -110
y = 110/2
y = 55
Since x = y- 34
x = 55-34
x = 21
Hence Sam will be 21years old now

As 5 miles is approximately 8 km, 150 miles is approximately
Answer:
240
Step-by-step explanation:
5 150
-- -----
8 x
so you would then do 8 × 150 = 1200
then 1200 ÷ 5 = 240
so x = 240

what is the solution of 56= k-42
Answer:
k=98
Step-by-step explanation:
Let's solve your equation step-by-step.
56=k−42
Step 1: Flip the equation.
k−42=56
Step 2: Add 42 to both sides.
k−42+42=56+42
k=98

Answer:
c = 10.5
Step-by-step explanation:
Formula: the product of the lengths of the segments of one chord equal the product of the segments of the other.
a •d = c • b
7*12 = c*8
84 =8c
Divide by 8
84/8 = 8c/8
10.5 = c
Bob eats 1/4 of a pie and later eats 2/5 of the pie. What fractions remains?
Answer:
9/20
Step-by-step explanation:
After Bob eats 1/4 of the pie, he has 3/4 left. 2/5 of 3/4 is the same as (2/5)*(3/4) because "of" is used as multiplication in math. (2/5)*(3/4)=6/20, so he ate 6/20 of the pie. To get the answer, you need to solve 1-(1/4+6/20)=
1-(5/20+6/20)=20/20-11/20=9/20. I hope this helps and sorry if I made a mistake. :)
Tawana has $325.54 in her checking account. She must keep a balance of at least $300 to avoid a fee. She plans to write a check to pay her to pay her credit card bill of $125.43. how much must Tawana deposit in her checking account to maintain atleast the minimum balance?
hi
Answer: To pay her bill with the minimum balance to avoid the fee, she needs the total amountof $300+$125.43=$425.43. But she only has $325.54. So, the extra minimum amount she needs to deposit is 425.43-325.54=$99.89.
Hence, the answer is $99.89.

PLEASE HELP HURRYYY URGENTTT
Answer:
B
Step-by-step explanation:
Substitute the x- coordinate of the solution into each equation and if the value obtained is equal to the y- coordinate of the solution, then it is the equation.
A
y = - 2(4) + 4 = - 8 + 4 = - 4 ≠ 2 ← not the equation
B
y = - [tex]\frac{3}{4}[/tex] (4) + 5 = - 3 + 5 = 2 ← this is the equation

Pam's eye-level height is 324 ft above sea level, and Adam's eye-level height is 400 ft above sea level. How much farther can Adam see to the horizon? Use the formula d = StartRoot StartFraction 3 h Over 2 EndFraction EndRoot, with d being the distance they can see in miles and h being their eye-level height in feet. 1 mi StartRoot 6 EndRoot mi 19 mi 19 StartRoot 6 EndRoot mi
Answer:
B. StartRoot 6 EndRoot mi
√6 mi
Step-by-step explanation:
A. 1 mi
B. StartRoot 6 EndRoot mi
C.19 mi
D. 19 StartRoot 6 EndRoot mi
d = √(3h/2)
Where,
d = distance they can see in miles h = their eye-level height in feet
Pam:
h = 324 ft
d = √(3h/2)
d = √{(3 * 324)/2}
= √972/2
= √486
= √(81 * 6)
= √81 * √6
= 9√6 mi
Adam:
h = 400 ft
d = √(3h/2)
d = √{(3 * 400)/2}
= √1200/2
= √600
= √(100 * 6)
= √100 * √6
= 10√6 mi
How much farther can Adam see to the horizon?
Adam - Pam
= 10√6 - 9√6
= √6 mi
