Answer:
zinc = 152 grams
Step-by-step explanation:
Ratio of zinc to copper = 4 : 15
Copper = 570 grams
zinc = x grams
Find x
Ratio of zinc to copper = x : 570
Equate both ratios
4 : 15 = x : 570
4/15 = x/570
Cross product
4 * 570 = 15 * x
2,280 = 15x
x = 2,280/15
= 152
x = 152 grams
zinc = 152 grams
What is the interest you will pay if you borrowed $1,250 at 4% interest for 4 years?
Answer:
$200
Step-by-step explanation:
The formula for calculating interest = principal x interest rate x time
principal is the amount borrowed = $1250
interest rate = 4%
Time = amount of years the money is borrowed for
$1250 x 0.04 x 4 = $200
Answer:
$200
Step-by-step explanation:
The slope, m, of a linear equation can be found using the formula m = StartFraction y 2 minus y a Over x 2 minus x 1 EndFraction., where the x- and y-values come from two ordered pairs, and (x1, y1) and (x2, y2).
Answer:
Please check the explanation.
Step-by-step explanation:
Given the points
(x₁, y₁)(x₂, y₂)Using the formula to determine the slope between (x₁, y₁) and (x₂, y₂) of the linear function
Slope = m = [y₂ - y₁] / [x₂ - x₁]
For example, let the points be
(x₁, y₁) = (1, 2)
(x₂, y₂) = (3, 4)
Determining the slope between
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [3 - 1]
= 2 / 2
= 1
Thus,
The slope of the line between the points (1, 2) and (3, 4) will be: m = 1

Including Jose, there are eight people in his family. If order matters, how many ways can he arrange his family members into a row of five seats if Jose must sit in the first seat?
Answer:
840 ways
Step-by-step explanation:
From the above question, we are told that order matters, hence, to solve the above question, we use the Permutation formula.
P(n, r) = nPr = n!/(n -r)!
From the above question,
Since Jose is included in the 8 people and he takes the first seat
n = 8 - 1 = 7 people
r = 5 - 1 = 4 seats
This is because, once Jose takes the first seat, there are 4 seats left with 7 people waiting to be seated
Hence,
7P4 = 7!/(7 - 4)!
7P4 = 7!/3!
7P4 = 5040/6
7P4 = 840 ways
Answer:
840

Exact Form: 15/2
Decimal Form: 7.5
Mixed Number Form: 7 1/2
Step-by-step explanation:
Answer:
1[tex]\frac{1}{14}[/tex]
Step-by-step explanation:
Turn the mixed fractions into improper fractions:
2 1/2 = 5/2
2 1/3 = 7/3
5/2 ÷ 7/3
Replace the division sign with a multiplication sign by reciprocating 7/3.
5/2 × 3/7
Multiply the numerators and the denominators.
= 15/14
Simplify 15/14 by turning it into a mixed fraction.

Frank Catton, the general manager of Billybob's floating raft hotel and Casino in Tunica Mississippi, has installed the "The Wheel of Doughnuts" at the check in desk. When you check in, you spin the wheel and a plate containing that many hot
doughnuts is delivered to your room the next moming for free. If your spinlands on an orange slot you get free hot chocolate too
(Give a fraction or round to 1 decimal place)
A. What is the probability that you get 7 doughnuts and hot chocolate? I
8. What is the probability that you get 7 doughnuts or hot chocolate?
Answer:
P( 7 doughnuts or hot chocolate)=0.40
Step-by-step explanation:
From the question we are told that
Total number of plates [tex]n=10[/tex]
1)Generally the probability that you get 7 doughnuts and hot chocolate is mathematically given as
7 doughnuts and hot chocolate= 1 slot
Therefore
P( 7 doughnuts and hot chocolate)= 1/10
P( 7 doughnuts and hot chocolate)= 0.10
2)Generally the probability that you get 7 doughnuts or hot chocolate is mathematically given as
P( 7 doughnuts or hot chocolate)=P(7 doughnuts)+P(hot chocolate)-P( 7 doughnuts and hot chocolate)
1 plates contains 7 doughnuts
P(7 doughnuts)=1/10
P(7 doughnuts)=0.10
4 plates contain hot chocolate
P(hot chocolate)=4/10
P(hot chocolate)=0.4
7 doughnuts and hot chocolate= 1 slot
P( 7 doughnuts and hot chocolate)= 1/10
P( 7 doughnuts and hot chocolate)= 0.10
Therefore
P( 7 doughnuts or hot chocolate)=0.10+0.4-0.10
Therefore
P( 7 doughnuts or hot chocolate)=0.40
The probability of getting 7 doughnuts or hot chocolate is 0.4

Isabelle, Joel, and Bryan sat on their grandmother's porch shelling peas for dinner. There were 2 big bowls of peas, and each person shelled an equal amount. How many bowls of peas did each person shell?
Answer:
2/3 bowls of peas
Step-by-step explanation:
Given that there were 2 big bowls of peas, and each person shelled an equal amount. Since there are three persons, the ratio of the number of bowls of peas available to the number of persons will give the number of bowls of peas did each person shell.
Hence each person must have shell
= 2/3 bowls of peas

June needs at least $575 to go on a vacation. She earns $10 an hour for babysitting and already has $252 saved for the trip. Which inequality can be used to find the number of hours she needs to babysit
Answer:
[tex]252 + 10h \ge 575[/tex]
Step-by-step explanation:
Given
[tex]Savings = 252[/tex]
[tex]Target=575[/tex] -- atleast
[tex]Earnings = \$10[/tex] per hour
Required
Represent as an inequality
Suppose that she babysits for h hours, her total earnings would be:
[tex]Total\ Earnings = 10h[/tex]
In inequalities:
At least means [tex]\ge[/tex]
So, when the total earnings is added to her savings, we have:
[tex]Savings + Total\ Earnings \ge Target[/tex]
Substitute values for Savings, Total Earnings and Target
[tex]252 + 10h \ge 575[/tex]

Find the value of x, giving reasons for your answer:
Answer:
x = 55
Step-by-step explanation:
[tex](x + 40) \degree = (150 - x) \degree \\ (vertical \: \angle s) \\ \\ x + 40 = 150 - x \\ \\ x + x = 150 - 40 \\ \\ 2x = 110 \\ \\ x = \frac{110}{2} \\ \\ x = 55[/tex]
Answer:
x = 55°
Step-by-step explanation:
When any 2 lines intersect each other at one point , the vertically opposite angles are always equal. Hence ,
[tex]150 - x = x + 40[/tex]
[tex] = > x + x = 150 - 40[/tex]
[tex] = > 2x = 110[/tex]
[tex] = > x = \frac{110}{2} = 55[/tex]
