Answer:
63 dm (aproximadamente)
Explicación paso a paso:
Dada a medida dos dous lados do triángulo: 54 dm e 32,4 dm.
Dado que se afirma que o terceiro lado é o hipoteno, que é o lado máis longo dun triángulo rectángulo, o hipoteno (h) pódese obter así:
h = sqrt (54 ^ 2 + 32,4 ^ 2)
h = sqrt (2916 + 1049,76)
h = sqrt (3965,76)
h = 62,974280
h = 63 dm (aproximadamente)

1. Fiona Wolfe regular pay is $9 an hour and time-and-a-half for anything over 40 hours. Last week she worked 46 hours at her full-time job. She also worked 7 hours last week at a part-time job that pays $11 an hour. What total gross pay did she earn last week from both jobs?
Answer:
$518
Step-by-step explanation:
The total gross payment = full-time payment + part-time payment
Given that:
She worked 46 hours for her full-time payment and time-and-a-half for anything and she is being paid $9 per hour;
and also worked for 7 hours for her part-time payment and she is being paid $11 per hour and time-and-a-half for anything
Then, the total gross payment = $46(9 1/2) + $7(11 1/2)
The total gross payment = $46(9.5) + $7(11.5)
The total gross payment = $437 + $80.5
The total gross payment = $517.5
The total gross payment ≅ $518

The school store sells markers for $0.25 each and pencils for 0.50 each.Anthony spent $ 5.50 to buy a total of 16 markers and pencils. How many markers did Anthony buy?
Answer:
The answer to your question is Antony bought 5 pens
Step-by-step explanation:
pens = p = $0.35
pencils = n = $0.15
total amount = 12
total money spent = $2.80
Process
1.- Write equations
p + n = 12 -------------- (l)
0.35p + 0.15n = 2.80 --------------(ll)
2.- Solve the system of equations by elimination
Multiply equation l by - 0.35
- 0.35p - 0.35n = -4.2
0.35p + 0.15 n = 2.8
0 - 0.2n = -1.4
Solve for n
n = -1.4 / -0.2
n = 7 He bought 7 pencils
3.- Find the value of p
p + 7 = 12
p = 12 - 7
p = 5 He bought 5 pens

Identify the two rational numbers.
O A. 1.01
O B. 57
O c.
- 2 /
O D. 1.010010001...
Answer: A. 1.01 Same as 1 1/100 fractions are rational
B. 57 Integers are rational. (Invisible implied denominator is 1)
Step-by-step explanation: c might be, but the denominator is not specified-- or maybe / is supposed to mean square root. So probably not.
D. NO, non-repeating decimal numbers are irrational

what is excess reagent
Answer:
We are commonly asked to find the extra reactants in a chemical equation. We can find it after balancing the equation and seeing the amount of moles that are present for each substance. Hence in chemistry and thermodynamic reactions it is the extra reactants that are not used up during the combustion process and therefore is excess of a said element.There are also limiting reagent which is the substance that limits the amount that can react and can be produced in a chemical reactionRate positively and give brainlist
The limiting reagent in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. The amount of product formed is limited by this reagent, since the reaction cannot continue without it.
why is excess reagent used:
A good way to ensure that one reactant fully reacts is to use an excess of the other reactant. This is financially efficient when one of the reactants is very cheap. When one reactant is in excess, there will always be some left over.
how do you find the excess reagent:
The reactant that produces a lesser amount of product is the limiting reagent. The reactant that produces a larger amount of product is the excess reagent. To find the amount of remaining excess reactant, subtract the mass of excess reagent consumed from the total mass of excess reagent given

A picture of two horses pulling a carriage to the left.
A free body diagram with 5 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline = negative 14,700 N. The second vector is pointing right, labeled F Subscript f Baseline = 75 N. The third vector is pointing upward, labeled F Subscript N Baseline = 14,700 N. The fourth vector is pointing left, labeled F Subscript pi Baseline = negative 1000 N. The fifth vector starts at the tip of the fourth vector, is pointing left, labeled F Subscript p2 Baseline = 800 N. The up and down vectors are the same length. The right vector is shorter than the left vector.
