Answer:
El precio de cada kilogramo de naranja y de manzana es 0.9 soles y 2 soles respectivamente.
Step-by-step explanation:
Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.
Resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.
En este caso, se debe plantear un sistema de ecuaciones. Se determinan las variables:
x: precio de cada kilogramo de naranjay: precio de cada kilogramo de manzanasJuan el primer día gastó 8,90 soles en total al comprar 1 kg de naranjas y 4 kg de manzanas; y el segundo día gastó 24,50 soles al comprar 5 kg de naranjas y 10 kg de manzanas. Entonces el sistema de ecuaciones a resolver es:
[tex]\left \{ {{x+4*y=8.90} \atop {5*x+10*y=24.50}} \right.[/tex]
Se decide resolver el sistema a través del método de sustitución, que consiste en despejar una de las incógnitas en una de las ecuaciones y sustituir su valor en la siguiente. En este caso despejando la variable x de la primera ecuación se obtiene:
x= 8.90 - 4*y
Reemplazando esta expresión en la segunda ecuación se obtiene:
5*(8.90 -4*y) + 10*y=24.50
Resolviendo se obtiene:
5*8.90 -5*4*y + 10*y=24.50
44.5 -20*y + 10*y=24.50
-20*y + 10*y=24.50 -44.5
-10*y= -20
y= (-20)÷ (-10)
y= 2
Reemplazando el valor de y obtenido en la expresión x= 8.90 - 4*y se obtiene:
x= 8.90 - 4*2
x= 8.90 - 8
x=0.9
El precio de cada kilogramo de naranja y de manzana es 0.9 soles y 2 soles respectivamente.
PLEASEEE SOMEONE HELP ME ON THIS!!!! It’s due in a couple hours
Answer:
x = 8.0 m
Step-by-step explanation:
With the angle presented, I'm assuming you know basic trigonometry. We know cosθ = adj/hyp from SOH CAH TOA. We have angle and hypotenuse, so plugging in those values we get cos(20°) = x / 8.5. Solve for x to get 8.5cos(20°) = 7.987387277 m = 8.0 m.

Answer:
A=36 a means area
Step-by-step explanation:
A=a+b/2
h=6+12/2
times 4=36
Answer:
=36cm^2
Step-by-step explanation:
6-12=6 (total cm of the bases for triangle B and C)
6/2= 3 (base of B and C trialngleis 3 )
Triangle formula: bh 1/2
(base)b= 3cm
height(h)=4
Formula: (3)(4) 1/2
=12 1/2
=6cm^2
^ area of 1 triangle
There are 2, so
6*2=12cm^2 (area of triangles )
Area of rectangle: L*W
4*6=24cm^2
Total area of trapezoid
=24cm^2+12cm^2
=36cm^2

Answer:
X= 42 degrees
Step-by-step explanation:
When combining 3x+12 and x, this results in a 180 degree angle to be formed. Therefore create the equation 3x+12+x=180 to get the value of X.
3x+12+x=180
4x+12=180
-12. 12
4x= 168
x= 42

Step-by-step explanation:
Hypotenuse = x
Base = 4
Perpendicular = [tex]\sqrt{84}[/tex]
Using Pythagoras Theorem:
[tex]\sf H^2 = P^2 + B^2\\\\ x^2 = (\sqrt{84} )^2 + (4)^2\\\\x^2 = 84 + 16\\\\x^2 = 100\\\\Taking \ sq \ root \ on \ both \ sides\\\\x = 10\\\\\rule[225]{225}{2}[/tex]

~AH1807Express 0.0175 in scientific notation.
Answer:
Step-by-step explanation:
1.75 x 10^-2
Answer:To equal the original number, you would have to multiply 1.75 by 0.01 or 10-2. Therefore, the proper scientific notation for 0.0175 would be 1.75 x 10-2.

What is the slope and y-intercept of y=-3x+7?
Answer:
The slope is -3 and the y-intercept is (0, 7)
Step-by-step explanation:
In the slope-intercept form (y=mx+b), m is the slope and b is the y-intercept. -3 is substituted for m and 7 is substituted for b in your equation.

The value is 18.84.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
3.14 x 6
Multiply the values.
= 18.84
Thus,
The value is 18.84.

Corey needs at least 2 gallons of paint to make a mural. If Corey has 6 quarts and 3 pints of paint, will he be able to make a mural?
Answer:
no
Step-by-step explanation:
4 quarts = 1 gallon, so he would have 1.5 gallons.
8 pints = 1 gallon, he would need 4 pints to have 2 gallons
Answer:
No he will not.
Step-by-step explanation:
6 quarts to a gallon is 1.5
3 pints to a gallon is 0.375
you add those together you get 1.875 not 2

In a fruit cocktail, for every 20 ml of orange juice you need 10 ml of apple juice and 15 ml of coconut milk. What proportion of the cocktail is apple juice?
Give your answer as a fraction in its simplest form.
Answer:
5/9
Step-by-step explanation:
First, find the total number of mL in the drink:
20 + 10 + 15
= 45
There are 10 mL of apple juice, so the proportion will be 10/45
Simplify this by dividing the numerator and denominator by 5:
10/45
= 5/9
So, 5/9 is the proportion of the cocktail that is apple juice

The time t required to do a job varies inversely as the number of people working. It takes 4 hr for 7 cooks to prepare the food for a wedding rehearsal dinner. How long will it take 8 cooks to prepare the dinner?
9514 1404 393
Answer:
3 1/2 hours
Step-by-step explanation:
If there are 8/7 times as many cooks, it will take 7/8 the amount of time. (That's what "inversely proportional" means.)
(7/8)(4 h) = 28/8 h = 3 1/2 h
It will take 8 cooks 3 1/2 hours to prepare the dinner.
