Divide 144g in the ratio 7: 11
Answers
Answer:
88:56 = 11:7
Step-by-step explanation:
Step One
Add the two ratios together 11 + 7 = 18
Now set up a ratio to solve for 11 parts out of 18
11:18 = x:144 Proportion
11 / 18 = x / 144 Equation: Cross mulitiply
11*144 = 18x Combine the left side
1584 = 18x Divide by 18
1584 / 18 = x
88 = x
That is the larger amount (11 is larger than 7)
Find the smaller amount
144 - 88 = 56
The two amounts are in the ratio of 11:7
88:56 = 11:7
I hopes this helps a little bit
Answer:
56g and 88g
Step-by-step explanation:
7x+11x=144
18x=144
x=144/18
x=8
7x=7*8=56g
11x=11*8=88g
Ajar contains $36.25 in dimes (10 cents) and quarters (25 cents). There are 250
coins in the jar. How many quarters are there in the jar?
Answers
Answer:
Step-by-step explanation:
The jar contains 2 types of coins dimes and quarters
the total amount is equal to 36.25 dollars
the total number of coins is 250
let number of dimes be x and quarters be y
let us put the equation
0.10x + 0.25y = 36.25
for our convinience convert all money to cents i.e. = 3625 cents
now the equations are
10x + 25y = 3625
x + y = 250
we need to solve for y i.e. number of quaters
y = 250 - x
rewrite the equation substituting y in x place
10(250 - y) +25 y = 3625
2500 - 10y +25y = 3625
15y = 1125
y = 75
so the number of quarters = 75
cross checking :
number of dimes = 250 - 75 = 175
total = 10x175 + 25x75 = 1750 + 1875 = 3625 = $36.25

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
For 3 dozen cookies = 1 1/2 cups = 3/2 cups
For 1 dozen cookies = 3/2 * 1/3 = 1/2 cups needed
So, for 7 dozen cookies = 1/2 * 7
= 3 1/2 cups needed
Hence, for 7 dozens cookies 3 1/2 cups needed.

The first side of a triangle is 4 inches longer then twice th second side the third side of a trianhle
Answers
Question:
The first side of a triangle is four inches longer than twice the
second side. The third side of the triangle is 5 inches shorter than
the sum of the other two sides. The perimeter is 72 inches. Find
the lengths of the three sides.
Answer:
The sides of the triangle are: 11.5, 27 and 33.5
Step-by-step explanation:
Let the first side be f, the second be s and the third be t.
So, we have:
[tex]f =4 + 2s[/tex]
[tex]t = f + s - 5[/tex]
[tex]Perimeter = 72[/tex]
Required
Determine the length of the three sides
Perimeter is calculated as:
[tex]Perimeter = f + t + s[/tex]
Substitute values for f and t
[tex]Perimeter = 4+2s + f+s-5 + s[/tex]
[tex]Perimeter = f+2s +s+s-5+4[/tex]
[tex]Perimeter = f+4s-1[/tex]
Substitute values for f and Perimeter
[tex]72 = 4+2s+4s-1[/tex]
[tex]72 = 2s+4s-1+4[/tex]
[tex]72 = 6s+3[/tex]
Collect Like Terms
[tex]6s = 72 -3[/tex]
[tex]6s = 69[/tex]
[tex]s= 11.5[/tex]
[tex]f =4 + 2s[/tex]
[tex]f = 4 + 2 *11.5[/tex]
[tex]f = 27[/tex]
[tex]t = f + s - 5[/tex]
[tex]t=27+11.5 - 5[/tex]
[tex]t=33.5[/tex]
The sides of the triangle are: 11.5, 27 and 33.5
Zamir needs to determine the height of the building
What’s the Height “A”
What’s Height “B”
What’s the Height of “X”
PLEASE
Answers
Answer:
Height of the building = 115.4 ft.
Step-by-step explanation:
Height of building = AB + 46.4 + CD + 30.5
By applying Pythagoras theorem in ΔABP,
(26)² = (10)²+ (AB)²
676 - 100 = AB²
AB² = 576
AB = 24 ft
By applying sine rule in ΔCDE,
cos(60°) = [tex]\frac{CD}{CE}[/tex]
CD = CE × [tex]\frac{1}{2}[/tex]
CD = [tex]\frac{29}{2}[/tex]
CD = 14.5 ft
Total Height = 24 + 46.4 + 14.5 + 30.5
= 115.4 ft

Decrease £843 by 91% rounded to 2 DP
Answers
Answer:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
91% = 91/100 = 91 ÷ 100 = 0.91.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 91% of its value.
Percentage decrease = 91% × 843
New value = 843 - Percentage decrease
Calculate the New Value
New value =
843 - Percentage decrease =
843 - (91% × 843) =
843 - 91% × 843 =
(1 - 91%) × 843 =
(100% - 91%) × 843 =
9% × 843 =
9 ÷ 100 × 843 =
9 × 843 ÷ 100 =
7,587 ÷ 100 =
75.87
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 843 =
75.87 - 843 =
- 767.13
Proof.
Calculate percentage decrease:
Percentage decrease =
91% × 843 =
91 ÷ 100 × 843 =
91 × 843 ÷ 100 =
76,713 ÷ 100 =
