1. 1. Un botellón de agua se ofrece al público en vasos de 0,12 litros. Si del botellón se pueden servir 45 vasos, la cantidad de agua que cabe en el botellón esUn botellón de agua se ofrece al público en vasos de 0,12 litros. Si del botellón se pueden servir 45 vasos, la cantidad de agua que cabe en el botellón es: a) 54 litros b) 12 litros c) 5,4 litros d) 0,54 litros
Answer:
c) 5,4 litros
Step-by-step explanation:
Un vaso de agua contiene 0,12 litros de agua.
Una botella contiene 45 vasos de agua.
El volumen completo de agua de la botella se distribuye en 45 vasos por igual.
Entonces,
[tex]0.12\ \text{L}\times 45=5.4\ \text{L}[/tex]
Por lo tanto, la cantidad de agua en la botella que se puede usar para servir 45 vasos es de 5.4 L.
Two pounds of onions cost $2.30. At this rate, how much will 5 pounds of onions cost?
Answer:
$5.75
Step-by-step explanation:
Find the unit rate first:
[tex]\frac{2.3 dollars}{2 pounds}[/tex]÷[tex]\frac{2}{2}[/tex]=[tex]\frac{1.15}{1}[/tex]
For every onion, you must pay $1.15. Multiply that by 5 in order to find the cost of 5 pounds of onions. It is $5.75. You can do this with any number to find the cost of any amount of pounds of onions. 4x1.15= 4.60 so the cost of 4 pounds of onions would be $4.60. 6x1.15=6.90 so the cost of 6 pounds of onions would be $6.90. Hope this helps.

Step-by-step explanation:
As a product development manager, one of your tasks is to determine the best price for an item to increase company profits. To do that, you need to take into account the cost of making the product, the labor of creating the product, and other overhead costs for the company (such as rent, electricity, etc.) If a product uses $14.25 in materials, $3.55 in labor, and $2.15 in overhead costs, what would you need to sell the product for in order to make a 20% profit on the item?
Answer:
$23.95
Step-by-step explanation:
In order to calculate the best selling price we first need to calculate the total amount of costs. Since we are provided with each individual cost we simply need to add these costs together to find the total.
$14.25 + $3.55 + $2.15 = $19.95
Now that we have the total amount of costs, we know that this is the break-even price that the product needs to sell for in order for the company not to lose money. If the company wants to make a 20% profit on each sale then you would need to increase this amount by 20%. This is done by multiplying the total costs by 1.20, which is 20% divided by 100 to turn it into decimal form, and then adding 1 to make it increase the total cost.
$19.95 * 1.20 = $23.95
Therefore, the company needs to sell each item for $23.95 in order to make a 20% profit.

what is the answer to this? 5(g+4)>15
Answer:
g > -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(g+4)=15
(5)(g)+(5)(4)=15(Distribute)
5g+20=15
Step 2: Subtract 20 from both sides.
5g+20−20=15−20
5g=−5
Step 3: Divide both sides by 5.
5g/5 = −5/5
G > -1
The solution of the inequality 5(g+4)>15 is g> -1.
Given Inequality:
5(g+4)>15
To solve the inequality, divide the inequality by 5
5(g+4) / 5 >15 / 5
g + 4 > 3
Now, subtract 4 from both side of inequality as
g + 4 - 4 > 3-4
g > -1.
Therefore, the solution is g > -1.

Andre and Priyabare tracking the number of steps they walk. Andre records that he can walk 6000 steps in 50 minutes. Priya writes the equation y=118x, where y is the number of steps and x is the number of minutes she walks, to describe her step rate. This week, Andre and Priya each walk for a total of 5 hours. Who walks more step?How many more?
Answer:
Andre walks 600 more steps than Priyabare
Step-by-step explanation:
Andre is 36,000 minutes while Priyabare walks 35,400. 1st you get the 6000 steps in 50 minutes from Andre and divide the 6000 by 50 to get 120 which you then multiply by 300 (minutes which is 5 hours) and get 36000. Then for Priyabare you multiply 118 by 300 as well (Again because equals 5 hours) and you will get 35,400 meaning Andre walked 600 more steps if you subtract the two.

Triangle ABC is shown with its inscribed circle drawn. The measure of angle ECF is 72 degrees. What is the measure of angle EGF? Explain or show your reasoning.
Answer:
108°
Step-by-step explanation:
CB and CA are tangents to the circle at points E and F respectively. GE and GF are radii of the circle with center G.
Since, radii of a circle are perpendicular to the tangents at the point of contacts.
[tex] \therefore GE \perp CB\\\\
\& \:GF \perp CA\\\\
m\angle GEC =m\angle GFC = 90\degree \\\\[/tex]
In quadrilateral GECF, by interior angle sum property:
[tex] m\angle C + m\angle E + m\angle F + m\angle EGF = 360\degree \\\\
\therefore 72\degree + 90\degree + 90\degree + m\angle EGF = 360\degree \\\\
\therefore 252\degree + m\angle EGF = 360\degree \\\\
\therefore m\angle EGF = 360\degree - 252\degree \\\\
\therefore m\angle EGF = 108\degree \\[/tex]
Answer:
108°Step-by-step explanation:
Since GE ⊥ BC and GF ⊥ AC,∠GEC = ∠GFC = 90°Sum of 4 angles is 360°, therefore:
∠ECF + ∠EGF = 360° - 180°∠EGF = 180° - 72° ∠EGF = 108°URGENT!!!!! I NEED HELP AYUDA

Step-by-step explanation:

In the given figure
∵ LJ // WK
∵ LP is a transversal
∵ ∠1 and ∠KWP are corresponding angles
∵ The corresponding angles are equal in measures
∴ m∠1 = m∠KWP
∴ ∠1 ≅ ∠KWP ⇒ (1)
∵ WK // AP
∵ WP is a transversal
∵ ∠KWP and ∠WPA are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠KWP = m∠WPA
∴ ∠KWP ≅ ∠WPA ⇒ (2)
→ From (1) and (2)
∵ ∠1 and ∠WPA are congruent to ∠KWP
∴ ∠1 and ∠WPA are congruent
∴ ∠1 ≅ ∠WPA ⇒ (3)
∵ WP // AG
∵ AP is a transversal
∵ ∠WPA and ∠2 are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠WPA = m∠2
∴ ∠WPA ≅ ∠2 ⇒ (4)
→ From (3) and (4)
∵ ∠1 and ∠2 are congruent to ∠WPA
∴ ∠1 and ∠2 are congruent
∴ ∠1 ≅ ∠2 ⇒ proved

How to determine the remainder in dividing the polynomial P(x) by a divisor x-1?
Answer:
Calculate P(1)
Step-by-step explanation:
Given
P(x)
[tex]Divisor = x - 1[/tex]
Required
How to determine the remainder
First, you equate the divisor to 0 to solve for x
i.e.
[tex]x - 1 = 0[/tex]
[tex]x = 1[/tex]
Next, substitute 1 for x in P(x)
Then solve for P(1)
Take for instance;
If
[tex]P(x) = x^3 - x^2 - 1[/tex]
Substitute 1 for x
[tex]P(1) = 1^3 - 1^2 - 1[/tex]
[tex]P(1) = 1 - 1 - 1[/tex]
[tex]P(1) = - 1[/tex]
Hence, the remainder is -1
