What is the measure of ZG?
A: 43
B: 73
C: 137
D: 116
Answer:
C, A, C
Step-by-step explanation:
1) Angle D corresponds to angle A, so since corresponding angles of similar triangles are congruent, it measures 64 degrees.
2) Angle E corresponds to angle B. To find the measure of angle B, we can start by using the fact that angles F and C correspond. This means that in triangle ABC, we have angles with measures of 64 degrees, 73 degrees, and angle B. It follows that angle B, and thus angle E, measures 43 degrees.
3) By the exterior angle theorem, the measure of angle G is equal to the measure of angles D and F combined. The measure of angle D is 64 degrees, and the measure of angle F is 73 degrees, so angle G measures 137 degrees.
The longer side of a rectangle has a length of 10. the rectangle is rotated around line k at this side. rectangle abcd has a perimeter of 32 units and will be rotated about line k. what is the three-dimensional solid created? what is the radius of a base?
The radius of the base after rotating the rectangle will be 5
What is the radius of the base?Since it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created is a cylinder.
Let's calculate its radius from the perimeter;
[tex]2p=32[/tex]
[tex]2(b+h)=32[/tex]
[tex]b+h=16[/tex]
[tex]b=16-h[/tex]
Also, [tex]bh=60[/tex]
Thus;
[tex]h(16-h)=60[/tex]
[tex]h^2-16h+60=0[/tex]
Using the online quadratic formula, we have h = 6
Thus; b = 16 - 6 = 10
Since the line of rotation is the center, and the radius is half the line segment of the basis, then the radius is 10/2 = 5.
Thus the radius of the base after rotating the rectangle will be 5

Integers are a subset of irrational numbers.
Answer:
yeah
Step-by-step explanation:
The natural numbers, whole numbers, and integers are all subsets of rational numbers. In other words, an irrational number is a number that can not be written as one integer over another. It is a non-repeating, non-terminating decimal.
Answer:
No irrationals are integers. Irrational numbers are by definition *not rational*, and all integers can represented as the rational

Let f(x)=x-5 and g(x)=x^2-7x+8 find f(x) × g(x)
Answer:
x³ - 12x² + 43x - 40
Step-by-step explanation:
f(x) × g(x)
= (x - 5)(x² - 7x + 8)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² - 7x + 8) - 5(x² - 7x + 8) ← distribute both parenthesis
= x³ - 7x² + 8x - 5x² + 35x - 40 ← collect like terms
= x³ - 12x² + 43x - 40
8. Which is the better buy: 200 g of coffee beans at $3.85 or 1 pound at $960?
How do I solve it
Answer:
200g of coffee beans
Step-by-step explanation: 453.592g = 1 pound going by 200 per $3.85 that would be way better than $960
Answer:
200 grams
Step-by-step explanation:
1 pound is 453.592 grams and 200 grams is 0.440925 of a pound. If you paid $3.85 for 200 grams you'd pay a little over $7.70 to get a pound. But if you paid $960 for a pound you'd have to pay a lot more money. So 200 grams of coffee beans is the better buy.

In one day, Annie traveled 5 times the sum of the number of hours Brian traveled and 2. Together they traveled 20 hours. Find the number of hours each person traveled.
Answer:
Annie- 17 hours, Brian- 3 hoursStep-by-step explanation:
Let the number of hours Annie travelled be a, and same of Brian be b
Then we have
a + b = 20a = 5b + 2Substituting a in the first equation
5b + 2 + b = 206b = 20 - 26b = 18b = 3Then finding a
a = 20 - 3 = 17So the answer is:
Annie- 17 hours, Brian- 3 hourspls help, i don’t understand this at alll !!!!!

The points A,B and C lie on a straight line
The coordinates of A are (9,0)
The coordinates of B are (7,4)
The coordinates of C are (1,q)
Work out the value of q
The value of q is 16.
What are Collinear Points?Collinear points are the points which are formed on a straight line, whether they are close or far away.
If three or more points are collinear, then they form on the same line.
The slope of each pair of points will be same.
Here if A, B and C are collinear,
Slope of AB = Slope of BC
(4 - 0) / (7 - 9) = (q - 4) / (1 - 7)
-2 = (q - 4) / -6
q - 4 = 12
q = 16
Hence the value of q is 16.

ou are buying batteries, a stereo, and some CDs from the I.B. Electronics store. You can buy from this store online or in a physical store. You have a coupon for 10% off that can only be used in the physical store and a $5.00 off coupon that can only be used online. The sales tax of 5% only applies to the physical store. Shipping for the online store is a flat rate of $6.99. You are trying to decide whether to shop at the physical store or the online store. Using the pricing information below, determine which store would cost less after all discounts, taxes, and shipping fees have been applied.
Item Quantity Physical Store Online Store
Batteries 2 packs $5.99/pack $4.99/pack
Stero 1 system $100.00/system $90.00/system
CDs 3 CDs $7.95/CD $8.95/CD
There is not enough information given.
It would cost less to purchase the items from the physical store.
It would cost less to purchase the items from the online store.
Answer:
It would be cheaper to use the online store
Step-by-step explanation:
the physical store added up to $129.04 and the online store was $128.82.
It would cost less to purchase the items from the physical store.
The correct option is C.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."
To calculate the total cost for each store, we need to take into account the discounts, taxes, and shipping fees.
For the physical store:
Batteries: 2 packs x $5.99/pack = $11.98
Stereo: 1 system x $100.00/system = $100.00
CDs: 3 CDs x $7.95/CD = $23.85
Subtotal: $135.83
After the 10% discount: $135.83 - 10% = $122.25
Sales tax: $122.25 x 5% = $6.11
Total cost: $122.25 + $6.11 = $128.36
For the online store:
Batteries: 2 packs x $4.99/pack = $9.98
Stereo: 1 system x $90.00/system = $90.00
CDs: 3 CDs x $8.95/CD = $26.85
Subtotal: $126.83
After the $5.00 discount: $126.83 - $5.00 = $121.83
Shipping fee: $6.99
Total cost: $121.83 + $6.99 = $128.82
Therefore, it would cost less to purchase the items from the physical store.
