please help me this is for algebra 1 the correct answer ill give brainly!

We conclude that Vincent has raised a total of $7.50

We know that initially, he has 20 candy bars.

He sells 3/10 of that total number, so the number of candy bars sold is:

N = (3/10)*20 = 6 candy bars.

And sells each for $1.25, so the total amount that has Vincent raised is:

R = 6*$1.25 = $7.5

We conclude that Vincent has raised a total of $7.50

Answer:

The sale price would be $3.75

Step-by-step explanation:

5*25%=1.25

5-1.25=3.75

the sale price of the shoes would be $3.75 because 5÷4=1.25 and 5-1.25=3.75, unless you are including tax. hope you get a good grade!

Answer:

90 pairs

Step-by-step explanation:

We can use clues from the problem in order to set up our inequality.

First, we know that a pair of earrings, [tex]p[/tex], costs $8.50. So, we can say that [tex]8.5p=[/tex] total profit.

That's a function we could use, but we need an inequality. Well, it says that Stephanie wants to make no less, or at least $765. This indicates that we need the 'greater than or equal to' symbol. Just replace the equal sign:

[tex]8.5p\geq 765[/tex]

Now we can isolate [tex]p[/tex] to find how many earrings she needs to sell to make a profit of at least $765.

[tex]8.5p\geq 765\\\\p\geq \frac{765}{8.5}\\\\p\geq 90[/tex]

Stephanie needs to sell at least 90 pairs of earrings.

Hope this helps!

Using the expected value formulae, the expected value of Annie entering the tournament is -$7950

Creating a probability distribution table :

Net amount won = (500 - 100) = 400 thousand

Amount lost = 100 thousand

X ___ : - 10,000 ____ 400,000

P(X) _ : __ 0.995 _______ 0.005

Using the expected value formulae:

E(X) = (0.995 × - 10,000) + (0.005 × 400,000)

E(X) = - 9950 + 2000

E(X) = -7950

Hence, the expected value of entering the tournament is -$7950

Answer:

13 favors

Step-by-step explanation:

Roll of ribbon = 4 1/3 feet long.

favor = 1/3 feet of ribbon

How many favors can she make?

Number of favors = Total roll of ribbon / length of each favors

= 4 1/3 feet ÷ 1/3 feet

= 13 / 3 × 3 / 1

= (13 × 3) / (3 × 1)

= 39 / 3

= 13

Number of favors = 13

Allison can make 13 favors from 4 1/3 feet of ribbon each of 1/3 feet

Answer:

y=3x-7

step by step explaination:

Answer:

not an answer but nice pfp

Explicación paso a paso:

Dada la altura de una pelota que se lanza directamente hacia arriba con una velocidad de 40 pies / modelada por la ecuación y = 40t -16t ^ 2

La pelota alcanzó su altura máxima cuando la velocidad es cero.

La velocidad se expresa como dy / dt

dy / dt = 40 - 2 (16) t

dy / dt = 40 - 32t

A altura máxima, dy / dt = 0

0 = 40-32t

-40 = -32t

t = 40/32

t = 1,25 s

Para obtener la altura máxima alcanzada, sustituirá t = 1.25 en la función modelada de la altura como se muestra;

y = 40t - 16t ^ 2

y = 40 (1,25) - 16 (1,25) ^ 2

y = 50 - 25

y = 25

Por tanto, la altura máxima que alcanza la pelota es de 25 m

Queremos encontrar la altura máxima alcanzada por una pelota que es lanzada hacia arriba. Veremos que la altura máxima es 25 pies.

Sabemos que la ecuación de la altura es:

y = 40*t - 16*t^2

Podemos ver que es una parabola con un coeficiente lider (el que multiplica la variable al cuadrado) negativo. Esto sinifica que el maximo esta en el vertice.

Para una parabola general:

a*x^2 + b*x + c

El vertice está en:

x = -b/(2a)

Así que en nuestro caso, el vertice de y = -16*t^2 + 40*t está en:

t = -40/(2*(-16)) = 1.25

Para encontrar la altura maxima evaluamos la ecuación en este valor de t:

y = 40*1.25 - 16*(1.25)^2 = 25

Es decir, la altura máxima es 25 pies.

Answer:

its asking you what the slope of the line is (rise/run) and for the point at which the line crosses the y axis (verticle line)

Step-by-step explanation:

When finding the slope you count the number of units up and the number of units across. This would be -1/1 or -1 because the graph shows a scale of 100, and the slope is going down 100, and across 100. this makes the slope negative since it's going downwards. so the slope would be -100/100 which would simplify to -1.

the y-intercept is where the line crosses the y axis. if this point is below the x-axis, then the y-intercept would be negative. in this problem however, the line crosses the y-axis at the origin (0,0)

so your equation would be y=1x+0, but simplified it would be y=x (the one isnt used because there is a single x value and the +0 is gone because it holds no value)

Answer:

5.08 inches

Step-by-step explanation:

Alyssa used a scale in which 1 inch represents 100 feet. If the actual landmark has a height of 508 feet, find the height of Alyssa's model in inches.

The scale =

1 inch = 100 feet

100 feet = 1 inch

508 feet = x inches

Cross Multiply

100 × x = 508 × 1

x = 508 × 1/100

x = 5.08 inches

The height of the model is 5.08 inches
