Answer:
35 grams
Step-by-step explanation:
The ratio of zinc to copper is 3 to 11
A jar of chemical contains 385 grams if copper
Therefore the number of grams of zinc it contains can be calculated as follows
3/11= x/385
11x= 385
x= 385/11
= 35 grams
Hence the chemical contains 35 grams of zinc

A car is 170 inches long. A truck is 85% longer than the car.
How long is the truck
Answer:
Step-by-step explanation:
if the car is 170 inches long
the truck is 85% longer
(170*85)/100=144.50 longer
the truck is 170+144.50=314.50
Answer:
314.5 inches100-85=15
170*0.15=25.5
170-25.5=144.5
170+144.5=314.5 inches

Given parallelogram SNOW, diagonals SO and NW intersect at D.
If SD = 9x+5 and OD = 13X - 3, find the length of SO
Answer:
The length of SO is 46 units
Step-by-step explanation:
In a parallelogram, diagonals bisect each other, which means meet each other in their mid-point
∵ SNOW is a parallelogram
∵ SO and NW are diagonals
∵ SO ∩ NW at point D
→ That means D is the mid-point of SO and NW
∴ D is the mid-point of SO and NW
∵ D is the mid-point of SO
→ That means D divide SO into two equal parts SD and DO
∴ SD = DO
∵ SD = 9x + 5
∵ DO = 13x - 3
→ Equate them
∴ 13x - 3 = 9x + 5
→ Subtract 9x from both sides
∵ 13x - 9x - 3 = 9x - 9x + 5
∴ 4x - 3 = 5
→ Add 3 to both sides
∵ 4x - 3 + 3 = 5 + 3
∴ 4x = 8
→ Divide both sides by 4
∴ x = 2
→ To find the length of SO substitute the value os x in SD and DO
∵ SO = SD + DO
∵ SD = 9(2) + 5 = 18 + 5 = 23
∵ DO = 13(2) - 3 = 26 - 3 = 23
∴ SO = 23 + 23 = 46
∴ The length of SO is 46 units

After completing the fraction division 5 divided by five-thirds, Miko used the multiplication shown to check her work. 3 times five-thirds = StartFraction 3 Over 1 EndFraction times five-thirds = StartFraction 15 Over 3 EndFraction or 5 Which is the most accurate description of Miko's work? Miko found the correct quotient and checked her work using multiplication correctly. Miko found the correct quotient but checked her work using multiplication incorrectly. Miko found an incorrect quotient but checked her work using multiplication correctly. Miko found an incorrect quotient and checked her work using multiplication incorrectly.
Answer:
Miko found an incorrect quotient and checked her work using multiplication incorrectly.
Step-by-step explanation:
The given expression is
[tex]\dfrac{5}{\dfrac{5}{3}}[/tex]
Applying the reciprocal rule we get
[tex]5\times \dfrac{3}{5}=5[/tex]
What Miko did was
[tex]3\times \dfrac{5}{3}=\dfrac{3}{1}\times\dfrac{5}{3}=\dfrac{15}{3}\ \text{or}\ 5[/tex]
So, Miko took the wrong values of the quotients and applied multiplication incorrectly.
Hence, Miko found an incorrect quotient and checked her work using multiplication incorrectly.

vi. Which one of the following is NOT a perfect square?
a. 625
b. 156
c. 196
Answer:
b. 156
Step-by-step explanation:
A "perfect square" is the product of an integer that is being multiplied by itself.
Choice a, 625, is a perfect square because it is the product of 25 multiplied by itself.
25 x 25 = 625Choice b, 156, is not a perfect square because you cannot find any integer that can be multiplied by itself that will result in 156 as a product. Therefore, this is the correct answer.
Choice c, 196, is a perfect square because it is the product of 14 multiplied by itself.
14 x 14 = 196I need help please

in march, Arnold finds a guitar with a price of $650 that he wants to buy, but he only has $300 saved. In September, Arnold has 75% more money saved, and the guitar is on sale for a 30% discount off the original price. The sales tax is 5% of the sale price. Does Arnold have enough money to buy the guitar in September? justify your answer
Answer:
Yew, he has enough money to buy the guitar in september.
Step-by-step explanation:
300*0.75=225 300+225=525
650*0.35=195 650-195=455
sales tax: 455*0.05=22.75 455+22.75=477.75
Yes , Arnold have enough savings to buy the guitar
Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the original price of the guitar be = $ 650
Let the initial savings of Arnold be = $ 300
Now , Arnold saved 75 % more than what he actually had
And , the equation will be
So , the new savings of Arnold is = 300 + ( 75/100 ) x 300
The new savings of Arnold is = 300 + ( 300 x 0.75 )
The new savings of Arnold is = 300 + 225
The new savings of Arnold is = $ 525
Now , the price of the guitar is discounted by = 30 %
And , the equation will be
So , the new price of the guitar after discount is = 650 - ( 30/100 ) x 650
The new price of the guitar after discount is = 650 - ( 650 x 0.30 )
The new price of the guitar after discount is = 650 - 195
The new price of the guitar after discount is = $ 455
Now , A sales tax of 5 % is priced on the guitar
And , the equation will be
So , the sale price of the guitar is = 455 + ( 5/100 ) x 455
The sale price of the guitar is = 455 + 22.75
The sale price of the guitar is = $ 477.75
Now , the new savings of Arnold is greater than the sale price of the guitar
$ 525 > $ 477.75
Therefore , Arnold have enough savings to buy the guitar
Hence , Yes , Arnold have enough savings to buy the guitar
Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75

Three guys rent a hotel room for the night. When they get to the hotel they pay the $30 fee, then go up to their room. Soon the bellhop brings up their bags and gives the lawyers back $5 because the hotel was having a special discount that weekend. So the three lawyers decide to each keep one of the $5 dollars and to give the bellhop a $2 tip. However, when they sat down to tally up their expenses for the weekend they could not explain the following details:
Each one of them had originally paid $10 (towards the initial $30), then each got back $1 which meant that they each paid $9. Then they gave the bellhop a $2 tip. HOWEVER, 3 • $9 + $2 = $29.
The guys couldn't figure out what happened to the other dollar. After all, the three paid out $30 but could only account for $29.

Answer:
y = -1/3x
Step-by-step explanation:
The slope of that are perpendicular lines are negative opposites of each other. If a line has a slope of 3, then a line perpendicular to it will have a slope of (-(1/3)).
Use the equation of a line in point-slope form to solve this;
y = mx + b
where "m" is the slope and "b" is the y-intercept.
Substitute the slope in;
y = (-1/3)x + b
Since it passes through the origin, then it has no y-intercept, therefore the equation of the line is;
y = -1/3x
which graph correctly represents y=4/5x+6
