Answer:

about 13.73 square feet

Step-by-step explanation:

We presume you want the area of the figure.

It can be decomposed into a triangle with base 3.6 ft and height 4.8 ft, together with a semicircle of diameter 3.6 ft.

The area of the triangle is given by ...

A = 1/2bh

For the given base and height, this is ...

A = (1/2)(3.6 ft)(4.8 ft) = 8.64 ft²

The radius is half the diameter, so the radius of the semicircle is 1.8 ft. The area of a whole circle of radius 1.8 ft is given by ...

A = πr² = π(1.8 ft)² = 3.24π ft²

We want the area of half the circle, so its area will be ...

semicircle area = (1/2)(3.24π ft²) = 1.62π ft² ≈ 5.089 ft²

Then the total area of the figure is ...

total area = triangle area + semicircle area

= 8.64 ft² + 5.09 ft²

total area = 13.73 ft²

Can someone pls tell me if this is correct? For the properties, <3 and the bottom one too

saul85 [17]

1. Commutative property of multiplication This is because it represents a*b=b*a
2. Associative property of multiplication. Multiplication problems end with the same product no matter the order of factors.
3. Correct
4. Correct
5. Associative property of addition. Even though the grouping symbols are different, it is equivalent because you are adding all the terms together.
6. Correct

The last one should also be associative property since it applies every time you combine like terms.
Just a reminder: Distributive property is only when you multiply in the form of a(b+c)=ab+ac

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

Mariulka [41]

Answer: her sales last week was $4300.

Step-by-step explanation:

Let x represent her her sales in a week.

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. This means that the commission she gets if she makes sales of $x is 0.0825x

She also earns a base salary of $675 per week. The expression for the total earnings for a week in which she made sales of $x would be

0.0825x + 675

if her total earnings for last week were $1,029.75, it means that

0.0825x + 675 = 1029.75

0.0825x = 1029.75 - 675

0.0825x = 354.75

x = 354.75/0.0825

x = $4300

Alik [6]

Answer:

see below:

Step-by-step explanation:

2y–6=0

a. slope intercept form using y = mx + b

y = 6/2

y = 3

b. slope: use the slope intercept form: y = mx + b

slope = m = 0

c. y-intercept = (0,3)

research suggests that the probability of a certain fuse malfunctioning increases exponentially as the concentration of an impur

Gennadij [26K]

Given that the probability <span>is modeled by the function
$y=3(257,959)^x[tex] where x is the impurity 
concentration and y, given as a percent, is the probability of the fuse 
malfunctioning.\\Then, the probability of the fuse malfunctioning for an impurity concentration of 0.17 is given by [tex]y=3(257,959)^{0.17}=3(8.316941)=24.95$

Therefore, the <span>probability of the fuse malfunctioning for an impurity concentration of 0.17 is 25% to the nearest percent.</span>

A clipboard cost $2.23.It cost $0.58 more than a notebook.Lisa bought two clipboards and one notebook.She paid with a ten dollar

Katen [24]

First you'd subtract .58 from 2.23 to get the price of the notebook.

2.23 - .58 = 1.65

(2.23×2)+1.65= 6.11

Now subtract 6.11 from ten to figure out the change amount.

10 - 6.11 = 3.89
