Answer:

34/100

Step-by-step explanation:

Add up all the jelly beans. 16+34+24+26=100

There are 34 blue jelly beans, so the probability is 34/100 but if you want to simplify that, it would be 17/50. If you were looking for a percentage that would be 34%

I need help really badly please

Answer:

y = 26

Step-by-step explanation:

The angles of a linear pair total 180°.

(2y +1)° +(5y -3)° = 180° . . . . the sum of the angles is 180°

7y -2 = 180 . . . . . . divide by °, collect terms

7y = 182 . . . . . . . . add 2

y = 26 . . . . . . . . . divide by 7

_____

<em>Additional comment</em>

The angle measures are (2(26) +1)° = 53°, and (5(26) -3)° = 127°. These total 180°, as they should.

For problem below, make use of the equation of motion of a vertically projected object: 20012 gtv t s  , where sis the heigh

faltersainse [42]

Answer:

$s=-4.905*t^{2} +20*t+120$

The equation corresponds to a quadratic function.

Step-by-step explanation:

Given

$s=-\frac{1}{2} gt^{2} +v_{0} t+s_{0}$

where

$g=9.81\frac{m}{s^{2} }\\ v_{0}=20\frac{ft}{s} \\ s_{0} =120 ft$

the function that describes the height of Joan’s basketball is

$s=-\frac{1}{2} (9.81\frac{m}{s^{2} })t^{2} +20\frac{ft}{s}*t+120 ft\\ s=-4.905*t^{2} +20*t+120$

The equation corresponds to a quadratic function.

Find the length and width of a rectangle that has the given perimeter and a maximum area. Perimeter: 116 meters

Naily [24]

Answer:

Length = 29 m

Width = 29 m

Step-by-step explanation:

Let x and y be the length and width of the rectangle, respectively.

The area and perimeter are given by:

$A=xy\\p=116=2x+2y\\y=58-x$

Rewriting the area as a function of x:

$A(x) = x(58-x)\\A(x) = 58x-x^2$

The value of x for which the derivate of the area function is zero, is the length that maximizes the area:

$A(x) = 58x-x^2\\\frac{dA}{dx}=0=58-2x\\ x=29\ m$

The value of y is:

$y = 58-29\\y=29\ m$

Length = 29 m

Width = 29 m

4x - 2y = -14<br> 3х - у = -8

oksian1 [2.3K]

are you trying to add them all together if so here how that would work

4x-3x=1x

2y-(1)y =1y(if the y is alone theirs a 1 always infront of it)

-14-8=-22
