Answer:
Pounds of raisins = 1.5 lb
Pounds of cashew = 3.5 lb
Step-by-step explanation:
Let
Pounds of raisins = x
Pounds of cashew = y
x + y = 5 (1)
4.50x + 9.50y = 40 (2)
From (1)
x = 5 - y
Substitute x = 5 - y into
4.50x + 9.50y = 40
4.50(5 - y) + 9.50y = 40
22.50 - 4.50y + 9.50y = 40
- 4.50y + 9.50y = 40 - 22.50
5y = 17.5
y = 17.5 / 5
= 3.5
y = 3.5lb
Substitute y = 3.5 into
x + y = 5
x + 3.5 = 5
x = 5 - 3.5
= 1.5
x = 1.5lb
Pounds of raisins = 1.5 lb
Pounds of cashew = 3.5 lb

Solve the inequality 2.5d+11.4<-1.3d solve the inequality
Answer:
d < -3
Step-by-step explanation:
2.5d+11.4<-1.3d
3.8d+11.4<0
3.8d<-11.4
d < -3
Just isolate and solve for x and remember, what you do to one side, you must do to the other.
Hope this helps!
Answer:
[tex]d < -3[/tex]
Step-by-step explanation:
Move the constant to the right-hand side and change its sign:
[tex]2.5d < - 1.3d - 11.4[/tex]
Move the variable to the left-hand side and change its signs:
[tex]2.5d + 1.3d < 11.4[/tex]
Collect like terms:
[tex]3.8d < - 11.4[/tex]
Divide both sides of the inequality by 3.8:
[tex]3.8 \div - 11.4 = - 3[/tex]
Therefore, the answer is d < -3.
a man buys a washing machine who price VAT(value added tax) is birr 175.its VAT is charged at 15% how much did the man actually pay?
Answer:
He actually paid a sum of $201.25
Step-by-step explanation:
We simply add the vat value to the cost of the machine
Mathematically, that’s (
175 + 15% of 175
= 175 + (15/100 * 175)
= 175 + 26.25
= $201.25

Answer:
D) 6
Step-by-step explanation:
Assumption method:
Assume all are postcards.
Total cost of postcards = 10 × $1
= $10
Difference between total = $22 - $10
= $12
Difference between subjects = $3 - $1
= $2
No. of magnets = $12 ÷ $2

On a field trip, there are 3 chaperones for every 20 students. There are 92 people on the trip. Answer these questions. If you get stuck, consider using a tape diagram.
How many chaperones are there?
Answer:
14
Step-by-step explanation:
20 times four is 80 so we already have 12 chaperones because there are 3 chaperones for every 20 students.
20 divided by 3 is 6.6
We cannot have .6 of a chaperone so we round up to 7
And since 7 can only go into 20 two times
That means there are two more chaperones
2+12 is 14
There are 14 chaperones for the 92 students
(Hope this helps and hope im right)
Answer:
80(students)
12(chaperons)
Step-by-step explanation:
since total of 92 people in the trip including student and chaperon,add groups of 23 to become 92 or use this equation:
(20+3)×y=92
23y=92
y=92/23
y=4
therefore,
20×4=80(students)
3×4=12(chaperons)

If $8000 is invested in an account for which interest is compounded continuously, find the amount of the investment at the end of 12 years for the following
interest rates.
(a) 2%
(b) 3%
(c) 4.5%
(d) 7%
Answer:
a) $1920, b) $2880, c) $4320, d) $6720
Step-by-step explanation:
a) Interest = Principal(Rate)(time)/100
Interest = $8000(12)(2)/100
Interest = $1,920
b) Interest = $8000(3)(12)/100
Interest = $2880
c) Interest = $8000(4.5)(12)/100
Interest = $4320
d) Interest = $8000(7)(12)/100
Interest = $6720

Find the gradients of lines A and B
Step-by-step explanation:
[tex]the \: gradient \: of \: line \: a \: is[/tex]
[tex]m = \frac{4}{1 } \\ m = 4[/tex]
[tex]the \: gradient \: of \: line \: b \: is[/tex]
[tex]m = \frac{ - 2}{1} \\ m = - 2[/tex]
Gradients of line A is equals to [tex]4[/tex] and gradients of line B is equals to [tex]-2[/tex].
What is gradients?" Gradients is defined as the ratio of difference of y-coordinates to the difference of x-coordinates."
Formula used
Gradients [tex]= \frac{y_{2}- y_{1}}{x_{2}- x_{1}}[/tex]
According to the question,
Given from the graph,
Coordinates of Line A
[tex](x_{1} ,y_{1} ) = ( 3,3)\\\\(x_{2} ,y_{2} ) = ( 4,7)[/tex]
Substitute the value in the formula we get,
Gradient of line A [tex]= \frac{7-3}{4-3}[/tex]
[tex]= 4[/tex]
Coordinates of Line B
[tex](x_{1} ,y_{1} ) = ( -1,3)\\\\(x_{2} ,y_{2} ) = ( -2,5)[/tex]
Gradient of line B [tex]= \frac{5-3}{-2-(-1)}[/tex]
[tex]= -2[/tex]
Hence, gradients of line A is equals to [tex]4[/tex] and gradients of line B is equals to [tex]-2[/tex].

Amir’s average math score for the first 4 tests of the school year is 88 Which equation can be used to calculate what Amir’s average must be on the next two tests so that his overall average is 90
Answer:
Equation that can be used = [tex]\frac{4(88)+2x}{6} = 90[/tex]
Step-by-step explanation:
Given that:
Amir's average on four tests = 88
Let,
x be the score on one test
For two tests = 2x
Sum of all scores = Average of four tests + Score of two tests
Sum of all scores = 4(88) + 2x
Total number of tests = 6
Overall average needed = 90
Now,
[tex]Average = \frac{Sum\ of\ quantities}{Number\ of\ quantities}\\90 = \frac{4(88)+2x}{6}\\\\\frac{4(88)+2x}{6} = 90[/tex]
Hence,
Equation that can be used = [tex]\frac{4(88)+2x}{6} = 90[/tex]

Kristen Lynn sells college textbooks on commission. She gets 4% on the first
$5000 of sales, 8% on the next $5000 of sales, and 12% on sales over
$10,000. In July of 1997 Kristen's sales total was $13,500.
Answer:
Step-by-step explanation:
5000 at 4% =200 (5000*0.04)
5000 at 8% = 400 (5000*0.08)
3,500 at 12% = 420 (3500*0.12)
200+400+420 = 1020
