Answer:

10% of the people at the picnic are neither.

Step-by-step explanation:

To get the answer,

1/2 + 2/5 = 9/10

10/10 - 9/10 = 1/10

1/10 = 10%

Thanks, I hope I got this right!

Maria decides to increase her homework time of 8 hours per week by 15% Calculate her new homework time. Give your answer in hour

Elena-2011 [213]

Answer:

Maria's homework time is now 9 hours 12 minutes.

Step-by-step explanation:

Since Maria decides to increase her homework time by 15%.

Then,

15% of 8 hours = $\frac{15}{100}$ x 8 hours

= 0.15 x 8 hours

= 1.2 hours

(Note that: 1.2 hours = 1 hour 12 minutes)

15% of 8 hours = 1 hour 12 minutes

her new homework time = 8 hours + 1 hour 12 minutes

= 9 hours 12 minutes

Maria's homework time is now 9 hours 12 minutes.

In the parallelogram below, solve for Y<br> Options <br> 4<br> 10<br> 25<br> 100

Lapatulllka [165]

Answer:

x = 4

y = 4

Step-by-step explanation:

the front triangle has two 40° angles (sum of all ∡'s must be 180°)

the unlabeled lower-left angle then is 40°; this angle corresponds to the angle in the other triangle labeled as 10y°

therefore, 10y = 40 so y = 4

Since opposite angles in a parallelogram are congruent then we can write:

40° + 25x° = 100° + 10(4)°

25x° = 140 - 40°

25x = 100°

x = 4

Alan is building a garden shaped like a rectangle with a semicircle attached to one short side. If he has 70 feet of fencing to

viktelen [127]

The dimension that would give the maximum area is 20.8569

<h3>How to solve for the maximum area</h3>

Let the shorter side be = x

Perimeter of the semi-circle is πx

Twice the Length of the longer side

$[70-(\pi )x -x]$

Length = $[70-(1+\pi )x]/2$

Total area =

area of rectangle + area of the semi-circle.

Total area =

$x[[70-(1+\pi )x]/2] + [(\pi )(x/2)^2]/2$

When we square it we would have

$70x +[(\pi /4)-(1+\pi)]x^2$

This gives

$70x - [3.3562]x^2$

From here we divide by 2

$35x - 1.6781x^2$

The maximum side would be at

$x = 35/2*1.6781$

This gives us 20.8569

Two quantities a and b have a proportional relationship where a is -4 and b -3 create an equation to represent this relationship

sladkih [1.3K]

Answer:

a = (4/3)b

Step-by-step explanation:

The governing equation here has the form y = kx, where k is the constant of proportionality.

Let's rewrite that as a = kb, and then substitute -4 for a and -3 for b:

-4 = k(-3), or k = 4/3

Then a = (4/3)b
