Answer:
each Tomskians will build 6 igloos per week
each Kyzylians will build 5 igloos per week
They achieved their goal
Step-by-step explanation:
6T + 5K ≥ 152
T = Tomskians
and each Tomskians will build 6 igloos per week
K = Kyzylians
and each Kyzylians will build 5 igloos per week
This is found by taking the coefficient on the inequality.
Substituting the values of T =10 and K = 19
6T + 5K ≥ 152
6*10 + 5*19 ≥ 152
60 + 95
155 ≥ 152
This is true, so they hired enough people.
Answer:
16
Step-by-step explanation:
Use PEMDAS (Parenesis, Exponents, Mutiplication, Division, Addition, Subtraction)
Using PEMDAS we add 5+3 for it is in parenesis. We get 8 from that. Finally, we multiply 8 with 2 to get 16.
Answer:
Step-by-step explanation:
To use the quadratic formula, we must write the quadratic in standard form, viz:
2x^2 - 4x + 7 = 0
Start by calculating the discriminant. That's b^2 - 4(a)(c). Here,
a = 2, b = -4 and c = 7, and so the discriminant for this particular problem is
(-4)^2 - 4(2)(7), or 16 - 56, or 40.
Recall that a positive discriminant indicates two real, unequal roots.
Now we write out the whole quadratic formula, with the appropriate constants inserted (see above):
-(-4) ± √40 4 ± (√4)(√10) 4 ± 2√10
x = --------------------- = ---------------------- = ---------------
2(2) 4 4
2 ± √10
which reduces to x = --------------
2
Answer:
A. The increase in the number of pounds a boy gains each year.
Step-by-step explanation:
A medical student is conducting a study to track boys’ weight from age 5 to age 18. The student graphs some data and determines the line of best fit is
y = 1.73x + 80.13 ............ (1)
where x represents the age of the boys and y represents the weight of the boy corresponding to his age.
Therefore, the slope of the equation (1) represents the increase in the number of pounds a boy gains each year. (Answer)
