Here are five sums. Use the distributive property to write each sum as a product with two factors. 2+7 5−10 −2^2 +++ 2−1/2
Question:
Here are five sums. Use the distributive property to write each sum as a product with two factors.
[tex](a)\ 2a + 7a[/tex] [tex](b)\ 5z - 10[/tex] [tex](c)\ c - c^2[/tex] [tex](d)\ r + r+ r+ r[/tex] [tex](e)\ 2x - \frac{1}{2}[/tex]
Answer:
[tex](a)\ 2a + 7a = 9a[/tex]
[tex](b)\ 5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]
Step-by-step explanation:
Required
Apply distributive property
[tex](a)\ 2a + 7a[/tex]
Apply distributive property [Factor out a]
[tex]2a + 7a = a(2 + 7)[/tex]
[tex]2a + 7a = a(9)[/tex]
Open bracket
[tex]2a + 7a = a*9[/tex]
[tex]2a + 7a = 9a[/tex]
[tex](b)\ 5z - 10[/tex]
Express 10 as 5 * 2
[tex]5z - 10 = 5z - 5*2[/tex]
Apply distributive property [Factor out 5]
[tex]5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2[/tex]
Express c as c * c
[tex]c - c^2 = c - c * c[/tex]
Apply distributive property [Factor out c]
[tex]c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r+ r+ r[/tex]
Express r as r * 1
[tex]r + r + r + r = r * 1 + r * 1 + r * 1 + r *1[/tex]
Apply distributive property [Factor out 1]
[tex]r + r + r + r = r(1+1+1+1)[/tex]
[tex]r + r + r + r = r * 4[/tex]
[tex]r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2}[/tex]
Express 2x as 4x/2
[tex]2x - \frac{1}{2} = \frac{4x}{2} - \frac{1}{2}[/tex]
Apply distributive property [Factor out 1/2]
[tex]2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]
Find the value of x. Round to the nearest tenth. 9 4 x = [?]
Answer:
26.4° (nearest tenth)
Step-by-step explanation:
[tex]\boxed{sinθ = \frac{opp}{hyp} }[/tex]
[tex]sinx = \frac{4}{9} [/tex]
Taking the inverse of sine on both sides:
[tex]x = sin^{ - 1} ( \frac{4}{9} )[/tex]
x= 26.4° (nearest tenth)

2. A kitten is gaining 0.6 pounds per week. The kitten is currently seven pounds. After how many weeks will the kitten be at least 10 pounds?
Answer:
Here is the answer
Step-by-step explanation:
The kitten weighs_____pounds every week -0.6 pounds
Weight of the kitten at current time -7 pounds
Weeks it will take for the kitten to reach 10 pounds -0.6+7=7.6
now round it off and you will get 7
∴the kitten will take 7 more weeks for getting to 10 pounds
The kitten will be at least 10 pounds after 5 weeks. Let's set up an equation to solve for the number of weeks needed for the kitten to reach at least 10 pounds.
Let "w" represent the number of weeks.
The weight of the kitten after "w" weeks can be calculated as:
Weight = Initial weight + (Weight gained per week * Number of weeks)
Weight = 7 + (0.6 * w)
We want to find the number of weeks when the weight is at least 10 pounds:Weight ≥ 10
Substituting the equation for weight:
7 + (0.6 * w) ≥ 10
Subtracting 7 from both sides:
0.6 * w ≥ 3
Dividing both sides by 0.6:
w ≥ 3 / 0.6
w ≥ 5
Therefore, the kitten will be at least 10 pounds after 5 weeks.

The base of a triangle is 24 millimeters and the height is 7 millimeters. What is the area of the triangle?
Answer:
84
Step-by-step explanation:
area of a triangle is represented by this equation: A= 1/2(b x h)
so we plug in the base for b and the height for h to get A=1/2(24 x 7) and now we solve accordingly. 24 x 7 is 160, and 160 x 1/2 is 84.
5. Write the slope-intercept form of the equation that passes through the point (-1, 2) and is perpendicular to the line y = 3/2x + 6
O y = 3/2x + 5/2
O y = 3/2x + 4/3
O y = -2/3x + 5/2
O y = -2/3x + 4/3
Answer:
D. y = -2/3 x + 4/3
Step-by-step explanation:
When you have a perpendicular line, everything except the y-intercept becomes opposite. So 3/2x + 6 will become -2/3x.
To find the slope, you have to plug the coordinates into the equation so far which is y = -2/3x + b
y = -2/3x + b
2 = -2/3(-1) + b
2 = 2/3 + b
4/3 = b
So the equation is y = -2/3 x + 4/3.

Answer:
a) Only the first one is an identity.
Step-by-step explanation:
1). 8 cos O tan O csc O = 8 simplifies to:
cos O tan O csc O = 1
cos O * (sin O / cos O) * (1 /sin O)
= cos O sin O / cos O sin O
= 1
So it is identity.
2) 13 sec^2 O/ cos^2 O - tan^2 O / cos^2O
= 13 sec^2 O - tan^2 O / cos^2 O
Now sec^2 O = 1 + tan^2 O, so we have:
(13( 1 + tan^2 O) - tan^2 O) / cos^2 O
= (12 tan^2 O + 13) / cos^2 O
This is not always = 2 so its not an identity.

Find the change between the first two sets:
12-9 = 3
14.4 - 10.8 = 3.6
3.6/3 = 1.2
Now find the change between the last two sets:
12 - -3 = 15
14.4 - 3.6 = 10.8
10.8/15 = 0.72
1.2 does not equal 0.72 so the answer is No

What goes on the green box?
A salesperson had $240, 000 in sales last year, which is 60% of the sales she had this year. Which equation could be used to determine x, the salesperson's total amount of sales, in dollars, for this year?
Answer: $400,000
Step-by-step explanation:
Let the salesperson's total amount of sales, in dollars, for this year be represented by x.
Therefore, 60% of x = $240,000
60/100 × x = $240,000.
0.6 × x = $240,000..
x = $240000 / 0.6
x = $400,000
Therefore, the salesperson's total amount of sales, for this year is $400,000.
