Answer: See explanation
Step-by-step explanation:
You didn't say what you'll like to calculate but let me help out.
Fourth year = 129 project.
Tenth year = 207 projects
We can form this into an arithmetic progression
Tn = a + (n-1)d
4th year = a + 3d = 129 ........ i
10th year = a + 9d = 207 ....... ii
Subtract equation i from equation ii
6d = 78
d = 78/6 = 13
This means that 13 new projects are added every year
For the first year, the number of projects done was:.
a + 3d = 129
a + 3(13) = 129
a + 39 = 129
a = 129 - 39 = 90
She worked on 90 projects in the first year.
Which fraction is closest to 1/2
Answer:
7/13 is closest to 1/2
Since 1/26 is closest to zero, 7/13 is closest to 1/2.
Marley used 7 cups of water to make 4 loaves of French bread. What equation can be used to model the total cups of water needed y for making x loaves of French bread? Write the equation in the form y =kx .
Answer:
[tex]\displaystyle y=\frac{7}{4}.x[/tex]
Step-by-step explanation:
Proportional Relationship
It's the type of relationships between two variables where their ratios are equivalent.
In a proportional relationship, one variable is always a constant value by the other. That constant is known as the constant of proportionality.
A proportional relationship between the variables x and y is written as:
y=k.x
For this problem, y represents the cups of water needed for making x loaves of French bread.
We know Marley used y=7 cups of water to make x=4 loaves of French bread. Substituting into the equation:
7=k.4
Solving for k:
[tex]\displaystyle k=\frac{7}{4}[/tex]
The equation to model the problem is:
[tex]\mathbf{\displaystyle y=\frac{7}{4}.x}[/tex]
Which expression is not equivalent to the other three?

Eight bottles of soda and four bags of chips cost $16. Six bottles of soda and 7 bags of chips cost $14. How much does a bottle of soda cost? How much does a bag of chips cost?
Answer: soda 1.75 dollars and chips is 0.50 dollars
Step-by-step explanation:you have to work out the question like a simultaneous equation so key s=soda and c=chips
8s+4c=16
6s+7c=14 make chips equal
56s+28c=112
24s+28c=56 Take the equations away
32s=56
S=56\32
S=7/4
S=1.75 sub that answer in the first equation
8*1.75=14
14+4c=16
4c=2
C=0.5

What is the area of △MNP?
A. 40 m2
B. 60 m2
C. 68 m2
D. 127.5 m2
answer is B. 60 m2
Step-by-step explanation:
17²=15²+MP²
289=225+MP²
289-225=64
So... MP²=64.... MP=8
8×15= 120
120÷2=60

Step-by-step explanation:
as we know sum of a triangle is 180 degree
so let's D= 2x,x
35+x+2x=180
3x+35=180
3x=180-35
3x=145
x=145÷3
x =46.06

Rob sells electronics and earns $625 per week, plus 12% of his sales. Last week, he sold $3250 worth of electronics. What was his total earnings for last week?
Answer:
$1,015
Step-by-step explanation:
Given that:
Weekly earning = $625
Commission = 12% of sales
sales made last week = $3250
Last week earning = weekly earning + commision on sale
Commission on sale = 12% of sales
Commission on sale = (0.12 * 3250) = $390
Last week earning = weekly earning + commision on sale
Last week earning = $625 + $390 = $1,015
