This recipe makes 20 cupcakes. Deepak only wants to make 15 cupcakes. How much of each ingredient does he need? Recipe: Makes 20 cupcakes 10 ounces butter 12 ounces sugar 8 ounces flour 4 eggs
Answer:
9.6 ounces of butter, 8 ounces of sugar, 12 ounces of flour, 4 eggs
Explanation: 20 / 16 = 4/5. 16 is four-fifths of 20. So multiply 4/5 with everything.
12 * 4/5 = 9.6 ounces
10 * 4/5 = 8 ounces
15 * 4/5 = 12 ounces
5 * 4/5 = 4 eggs

What is the value of x. Please help out. This is due today!
Answer:
70°
Step-by-step explanation:
In the context it says that Franklin St. is parallel to Washington St.
The 110° formed by Franklin St. and Mulberry St. is a supplementary angle to Angle x.
Supplementary angles are angles that add up to each other to make 180°
So lets subtract:
180 - 110 = 70°
Angle x = 70°

i need help on how to answer this if anyone knows how to please respond. Thank you!
Answer:
23.25 m^3
Step-by-step explanation:
First you must find the area of the base you find it like this:
A(area)=1/2(one half)3.1(base)2.5(height)
you get 3.875(this is the area of the base)
now you have to multiply the area of base times the area of height like this:
A(area)=3.875(area of base)6(height)=23.25
so the answer is 23.25m^3
Hope I'm right have a great day!

The blueprint's scale is
1 inch : 9 feet. If the gym's
area is 52 square inches on the
blueprint, what is the actual
square footage of the gym?
The area of the actual gym
is_square feet.
Answer:
4212 square feet.
Step-by-step explanation:
If the blueprint's scale is 1 inch : 9 feet.
Square both sides
(1in)² = (9ft)²
1in² = 81ft²
Given the gym's area as 52 square inches, hence;
52in² = x
Divide both expressions
1/52 = 81/x
x = 52 * 81
x = 4212ft²
Hence the area of the actual gym is 4212 square feet.
Which can be represented by the expression 17 – 2x? A. 17 less than twice a number B. the difference between 17 and twice a number C. a number x squared, subtracted from 17 D. 17 less than a number x squared
Answer:
B.
Step-by-step explanation:
If x is a number, then twice a number is 2x. The difference between 17 and 2x is 17-2x.
Common Error:
A. says 17 less than twice a number. Since it is 17 less, it is 2x-17 not 17-2x.
Hope this answer helped! :)

When did u hi the water? Round your answer to the nearest hundreth?
Answer:
5.33 Seconds
Step-by-step explanation:
This is because you have to do the quadratic equation and solve.
The time required to hi the water is 5.33 seconds.
What is a quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x as ax^2+bx+c=0 with a ≠ 0 . A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2.
For the given situation,
The function is h(t)= -16t^2+16t+370
The roots of this function can be found by using the formula,
[tex]t=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]t=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]
Here, a=-16, b=16, c=370
⇒ [tex]t=\frac{-16+\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex] or [tex]t=\frac{-16-\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex]
⇒ [tex]t=\frac{-16+\sqrt{23936} }{-32}[/tex] or [tex]t=\frac{-16-\sqrt{23936} }{-32}[/tex]
⇒ [tex]t=\frac{-16+154.712}{-32}[/tex] or [tex]t=\frac{-16-154.712}{-32}[/tex]
⇒ [tex]t=\frac{138.712}{-32}[/tex] or [tex]t=\frac{-170.712}{-32}[/tex]
⇒ [tex]t=-4.33[/tex] or [tex]t=5.33[/tex]
Time cannot be negative. So the value is 5.33.
Hence we can conclude that the time required to hi the water is 5.33 seconds.

Jorge has a swimming pool that is rectangular in shape. The length and width of the pool are 24 feet and 14 feet. He also knows that the pool has a consistent depth of 5 feet. He needs to add 4 drops of chlorine for every 50 cubic feet in his pool. How many drops of chlorine should Jorge use to chlorinate his pool properly?
Answer:
140 drops
Step-by-step explanation:
Length of the pool = 24 feet
Width of the pool = 14 feet
Depth of the pool = 5 feet
Volume of the pool = length × width × depth
= 24 ft * 14 ft * 5 ft
= 1,750 ft³
Volume of the pool = 1,750 ft³
He needs to add 4 drops of chlorine for every 50 cubic feet in his pool.
Number of 50 cubic feet in the volume of the pool = Volume of the pool / 50 ft³
= 1,750 ft³ / 50 ft³
= 35
Number of 50 cubic feet in the volume of the pool = 35
How many drops of chlorine should Jorge use to chlorinate his pool properly?
Number of drops of chlorine Jorge should use = number of drops per 50 ft³ × Number of 50 cubic feet in the volume of the pool
= 4 × 35
= 140 drops
Number of drops of chlorine Jorge should use = 140 drops

La respuesta correcta para esta pregunta abierta es la siguiente.
Aunque no se anexaron opciones o incisos para contestar, podemos comentar lo siguiente.
Cada material en sus distintos estados de agregación, cambia de volumen de forma diferente, sin embargo todos lo hacen en cierta medida. A esta propiedad se le llama Estados de Agregación de la Materia.
Las substancias cambian su composición debido a la presión o al cambio de temperatura a la que son sometidos. A ese proceso se le conoce como el estado de agregación de la materia, cuando las moléculas y átomos que constituyen esa matera se ve sometido a una transformación en su composición.
Podemos reconocer comúnmente cuatro estados de transformación de la materia, que son, el estado de plasma, el estado gaseoso, el estado líquido y el estado sólido
