Answer:
a. K=300.15
b. 300 Kelvin is greater
Step-by-step explanation:
a. If C=23. Place it in C=k-273.15
K=C+273.15 = 27+273.15
K=300.15
b. Put C=25, K=C=273.15
K=298.15 which is lesser than 300 Kelvins
Answer:
lower bound = 90 - 10 = 80 cm
upper bound = 90 + 10 = 100 cm
lower bound d = 1500 x 80 cm = 120,000 cm
upper bound d = 1500 x 100 cm = 150,000 cm
Answer:
14
Step-by-step explanation:
Substitute the given values for a and b into the expression and evaluate
a + b = 43 + (- 29) = 43 - 29 = 14
You just average the x and y. So for x it is (3+-5)/2 = -1 and for y it is (8+-1)/2=3.5.
The midpoint is (-1,3.5). See picture for a graphical explanation.
The vendor sold 124 sodas and 90 hot dogs.
Step-by-step explanation:
Let,
x be the number of sodas.
y be the number of hot dogs.
Total sold = 214
According to given statement;
x+y=214 Eqn 1
y= x-34 Eqn 2
Putting value of Eqn 2 in Eqn 1;

Dividing both sides by 2;

Putting x=124 in Eqn 2;

The vendor sold 124 sodas and 90 hot dogs.
