6*8+2*2+3*2=58
Answer:
b) 58
Step-by-step explanation:
b)
Formula for all of them:
A = bh
Big rectangle:
A = bh
A = (8)(6)
A = 48
Right rectangle:
A = bh
A = (2)(3)
A = 6
Bottom rectangle:
A = bh
A = (2)(2)
A = 4
Combined:
48 + 6 + 4

In 2016 the U.S. Census Bureau estimated the population of the United States at 322 million. If the annual rate of growth was about 0.81%, find the expected population at the time of the 2030 census. Round your answer to the nearest ten million.
Answer:
388,000,000
Step-by-step explanation:
So as we have 322 million
we want to take 0.81% of it and add to the total each year so
322,000,000*0.81%=2,608,200
322,000,000+2,608,200=324,608,200
and now do that for 22 more years so
We get 387,649,305.98 as our population
387,649,305.98 -------> 388,000,000

Rewrite the function to complete the square f(x) = x^2 + 4x + 41
Answer:
f(x)=(x+2)^2+37
Step-by-step explanation:
Got it right on Khan :)
The quadratic function f(x) = x² + 4x + 41 is converted into square form is f(x) = (x + 2)² + 37.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.
The quadratic function is given below.
f(x) = x² + 4x + 41.
The quadratic function is converted into square form by adding and subtracting the square of the half of the coefficient of x.
f(x) = x² + 4x + 41
Transform into square form. Then the quadratic function will be
f(x) = (x² + 4x + 4) + 41 – 4
f(x) = (x + 2)² + 37
The quadratic function f(x) = x² + 4x + 41 is converted into square form is f(x) = (x + 2)² + 37.

Write the number below as a fraction in its simplest form 0.˙49˙9 (more clearer picture is attached here)
Answer:
499/999
Step-by-step explanation:
The decimal number written is:
0.499...
Such that these 3 decimals are repeated as:
0.499499499...
Let's define this number as k
k = 0.499...
Let's multiply this number by 1000 (the same number of zeros as important decimals after the decimal point)
we get:
1000*k = (1000)*(0.499...) = 499.499...
Now we can subtract the original number k, so we get:
1000*k - k = 499.499... - 0.499...
In this way, we remove the part after the decimal point:
1000*k - k = 499.499... - 0.499...
(1000 - 1)*k = 499
999*k = 499
Now we can divide both sides by 999
(999*k)/999 = 499/999
k = 499/999
The fraction notation of our number is 499/999 (and this is the simplest form)
legs and hypotenuse
Answer:
Step-by-step explanation:
For a right triangle, the side that is opposite of the right angle is called the hypotenuse. This side will always be the longest side of the right triangle. The other two (shorter) sides are called legs.
Given the Trapezoid ABCD
Find the length of AD
Pls helppp
Answer:
AD = 230
Step-by-step explanation:
AD = 30x - 10
MN = 31x + 1
BC = 30x + 28
To find the length of AD, we need to generate an equation that will enable us to find the value of x.
Thus,
MN = ½(AD + BC) => Trapezoid Midsegment Theorem
Plug in the values
31x + 1 = ½(30x - 10 + 30x + 28)
(31x + 1) × 2 = 30x - 10 + 30x + 28
62x + 2 = 30x - 10 + 30x + 28
Add like terms
62x + 2 = 60x + 18
62x - 60x = -2 + 18
2x = 16
x = 16/2
x = 8
✅AD = 30x - 10
Plug in the value of x
AD = 30(8) - 10 = 230

Find the distance between the points A(2, 3) and B(4, 1).
Answer:
sqrt(8) or 2.828
Step-by-step explanation:
You use the distance formula which is sqrt((x2-x1)^2+(y2-y1)^2) where x2 can be either x value
Answer:
sqrt(8) units
Step-by-step explanation:
Use the formula d=sqrt((x2-x1)^2 + (y2-y1)^2). d=distance, and (x1, y1) and (x2, y2) are the points.
d=sqrt((4-2)^2 + (1-3)^2)
=sqrt(2^2 + (-2)^2)
=sqrt(4+4)
=sqrt(8)
A and B are sqrt(8) units apart.
Please help my on maths
Answer:
1) m<RAS = 126
2) x = 144
Step-by-step explanation:
1)
10x + 36 + 6x = 180
16x + 36 = 180
16x = 144
x = 9
<RAS:
10x + 36
10(9) + 36 = 126
2)
54 + 90 + y = 180
y + 144 = 180
y = 36
x + y = 180
x + 36 = 180
x = 144
Find the radius of the sphere with the given volume. (15 points)
Please show your work!
Answer:
r = 1/2
Step-by-step explanation:
sphere volume = 4/3πr³
4/3πr³ = 1/6π
divide both sides of the equation by π:
4/3r³ = 1/6
multiply both sides by 6:
24/3r³ = 1
reduce:
8r³ = 1
divide both sides by 8:
r³ = 1/8
r = 1/2

A restaurant has many vistors over the weekend.4/9 of the visitors are adults. If there were 380 adults, how many visitors were children? Answer
Answer:
475 children
Step-by-step explanation:
A restaurant has many vistors over the weekend.4/9 of the visitors are adults. If there were 380 adults, how many visitors were children? Answer
Step 1
We find the total number of visitors the restaurant had over the weekend. This is calculated as:
Let the total number of visitors = x
4/9 × Total number of visitors = 380 Adults
4/9 × x = 380
4x/9 = 380
Cross Multiply
4x = 9 × 380
x = 9 × 380/4
x = 855 visitors.
Step 2
The number of visitors that were children is calculated as:
Total number of visitors - Number of Adults
= 855 visitors - 380 Adults
= 475 children

Find the equation of a line, in slope-intercept form of a line that passes through the point (-5, -1) and is parallel to the line -2x + 4y = 8.
1. y = -1/2x +13/2
2. y = 1/2x - 3/2
3. y = -1/2x - 7/2
4. y = 1/2x + 3/2
Answer:
4. y = 1/2x + 3/2
Step-by-step explanation:
First, we need to change the line that's parallel into slope-intercept form.
-2x + 4y = 8
4y = 2x + 8
y = 1/2x + 2
If it's parallel, then it remains the same. So our slope is 1/2.
To find the y-intercept, you need to plug the coordinates into the equation.
y = 1/2x + b
-1 = 1/2(-5) + b
-1 = -5/2 + b
3/2 = b
y = 1/2x + 3/2
Could someone help me out with this
Hey! It's me again! You told me to answer this, so I will deliver ☺
Answer:
15/21
Step-by-step Explanation:
Because 1/3 and 2/7 do not have the same denominator, we will have to multiply them to get one that they'll both share.
In this case, you multiply both denominators, 3 and 7, to get 21.
We do the same with the numerators, but in a different way.
We're gonna multiply the numerators by the OTHER fractions' denominators this time. So, we do this:
1 x 7 = 7
2 x 3 = 6
We end up getting these fractions:
7/21
6/21
And now, we just subtract 6 from 21, to get 15.
And you get 15/21.
I hope I helped you, and a "Brainliest" is always appreciated! ☺
