Answer:
Option 1 , 2 & 5
Step-by-step explanation:
4 & 16 are perfect squares. So , 1/4 & 1/16 are also perfect squares. But 2 , 8 & 10 are not perfect squares. So root of 1/2 , 1/8 & 1/10 are irrational numbers.
Verification :-
1)[tex] \sqrt{ \frac{1}{10} } = \frac{ \sqrt{1} }{ \sqrt{10} } = \frac{1}{ \sqrt{2} \times \sqrt{5} } [/tex]
Hence , it is irrational.
2)[tex] \sqrt{ \frac{1}{8} } = \frac{ \sqrt{1} }{ \sqrt{8} } = \frac{1}{2 \sqrt{2} } [/tex]
So , it is irrational.
3)[tex] \sqrt{ \frac{1}{16} } = \frac{ \sqrt{1} }{ \sqrt{16} } = \frac{1}{4} [/tex]
So , it is rational.
4) [tex] \sqrt{\frac{1}{4} } = \frac{ \sqrt{1} }{ \sqrt{4} } = \frac{1}{2} [/tex]
So it is rational.
5) [tex] \sqrt{ \frac{1}{2} } = \frac{ \sqrt{1} }{ \sqrt{2} } = \frac{1}{ \sqrt{2} } [/tex]
Hence it is irrational.

A. -3x -24; x S 8
B. -3x -24; x 8
C. -3x <-24; x>-8
D. -3x >-24; x>-8
Answers
Step-by-step explanation:
Lets convert each sentence into an algebric inequality.
Product of -3 and a number (let it be x) :-[tex] = > - 3 \times x = - 3x[/tex]
-3x is atleast -24[tex] = > - 3x \geqslant - 24[/tex]
Lets solve the inequality.
Now , divide -3 on both the sides -
[tex] = > \frac{ - 3x}{-3} \geqslant \frac{ - 24}{ - 3} [/tex]
[tex] = > x \geqslant 8[/tex]
Last night, the temperature fell from 0°F to -13 in 4 § hours. What was the average temperature change per hour? Solve the division problem. 2 1 -13= - 4 5 5 The temperature drop per hour can be represented by I °F. QUICKLY
Answers
Answer:
3.25 degrees/hour
Step-by-step explanation:
Last night, the temperature fell from 0°F to -13°F in 4 hour.
We need to find the average temperature change per hour. It can be calculated by dividing the change in temperature per unit time.
Change in temperature = -13°F -0°F = -13°F
So,
[tex]C=\dfrac{-13}{4}\\\\=-3.25\ \text{degrees/hour}[/tex]
So, the change in temperature is 3.25 degrees/hour.
Answer:
-3.25 degrees an hour
Step-by-step explanation:
-13 ÷ 4 = -3.25

Answer:
Quantité totale d'essence consommée: 167 litres (arrondie à l'unité pres)
Nombre de jours du voyage: 12 jours (je pense! Je ne comprends pas "jours sants" ? Suivants? )
Distance parcourue pour aller à Pittsburgh: 1269.8 km
coût total de l'essence: $ 204.11
Coût moyen de l'essence consommée par jour (arrondi au centieme pres): $17.01
Distance parcourue par jour pour le retour: 613.5 km
Distance totale parcourue durant les vacances: 2496.8 km
Step-by-step explanation:
Jour 1 Montreal à Parc Sandbanks
2,3,4,5 Parc Provincal Sandbanks
6,7,8,9,10 Pittsburgh
11,12 Pittsburgh à Quebec
Distance: ajouter les numéros jours par jour.
Essence consommée: 6.7 litres pre 100, donc diviser la distance totale par 100 puis multiplier par litres par km
2496.8/100 = 24.968 × 6.7 = 167.2856 et arrondir le total: 167.3
Coût total de l'essence: Il faut multiplier le total consommée par la coût par litre, $1.22 167.3×1.22 = $204.11
Coût moyen de l'essence consommée par jour: $204.11 ÷ 12 jours = $17.01/jour
Distance parcourue par jour pour le retour: 1227km/2days = 613.5 km/jour
Distance totale parcourue durant les vacances: Ajoutez les distances journalières parcourues à Pittsburgh à la distance de retour à Quebec.
1269.8 + 1227 = 2469.8 km

following system of equations can be used to represent the situation. Determine the best method to solve the system
of equations. Then solve the system.
Answers
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation:
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10

Write a linear function f with f (5) = -1 and f(0) = -5.
f(x)=____
Answers
Answer:
We conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:
f(x) = 4/5x - 5Step-by-step explanation:
Given
f(5) = -1f(0) = -5f(5) = -1 means at x = 5, y = -1
Hence, the point (5, -1) lies on the line function.
f(0) = -5 means at x = 0, y = -5
Hence, the point (0, -5) lies on the line function.
Thus, the two points on the linear line function graph are:
(5, -1)(0, -5)Finding the slope between the points (5, -1) and (0, -5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-5\right)[/tex]
[tex]m=\frac{-5-\left(-1\right)}{0-5}[/tex]
[tex]m=\frac{4}{5}[/tex]
The slope-intercept form of the linear line function
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
We have already determined the slope which is: m = 4/5
We know the y-intercept can be determined by setting x = 0 and solving for y.
Thus, the point (0, -5) represents the y-intercept b = -5.
Now, substituting m = 4/5 and b = -5 in the slope-intercept form
[tex]y = mx+b[/tex]
y = 4/5x + (-5)
y = 4/5x - 5
Therefore, we conclude that the equation of a linear function with f (5) = -1 and f(0) = -5 will be:
f(x) = 4/5x - 5Write the number as a percent.
