Answer:
A)The angles in the smaller prism measure 90 degrees.
B)The perimeter of the rectangular bases changes by a factor of 2.
E)The area of the rectangular bases changes by a factor of 4.
Step-by-step explanation:
The right rectangular prisms are similar.
Which statements are correct? Check all that apply.
A)The angles in the smaller prism measure 90 degrees.
B)The perimeter of the rectangular bases changes by a factor of 2.
C)The surface area changes by a factor of 8.
D)The larger prism has twice the volume of the smaller prism.
E)The area of the rectangular bases changes by a factor of 4.
Solution:
Two polygons are said to be similar if they have the same shape, the ratio of their sides are in the same proportion and they have the same size of angles.
A) Since the bigger prism has angles with measure of 90°, hence the angles in the smaller prism will also measure 90.
Option A is correct.
B) Perimeter of bigger prism base = 2(2.2 + 0.8) = 6
Perimeter of smaller prism base = 2(1.1 + 0.4) = 3
The perimeter of the rectangular bases changes by a factor of 2 (6 / 3).
Option B is correct.
C) Surface area of bigger prism = 2(3.2*0.8 + 2.2*0.8 + 3.2*2.2) = 22.72
Surface area of smaller prism = 2(1.6*0.4 + 1.1*0.4 + 1.6*1.1) = 5.68
The surface area does not change by a factor of 8 (22.72 / 5.68 ≠ 8)
Option C is wrong
D) Volume of bigger prism = 2.2 * 3.2 * 0.8 = 5.632
Volume of smaller prism = 1.1 * 1.6 * 0.4 = 0.704
The larger prism volume is not twice of the smaller prism
Option D is wrong
E) Area of bigger prism base = 2.2*0.8 = 1.76
Area of smaller prism base = 2.2*0.8 = 0.44
The area of the rectangular bases changes by a factor of 4 (1.76 / 0.44 = 4)
There are 200 marbles in the bag, John picks 10 marbles out of
the bag and 6 of them are red. What would be an estimate for
the number of red marbles in the bag?
Answer:
Step-by-step explanation:
favorable success: 6/10
marbles: 200
So
P=Favorable cases/total cases
P=6(20)/10(20)

in the figure below, all lines intersect at point M. what is the measure of
Answer:
m∠GML= 65°
Step-by-step explanation:
m∠GML= 180°-(m∠GMH+m∠HMI)
= 180°-(85°+30°)
=180°-115°
m∠GML= 65
--------------------------
hope it helps...
have a great day!!
If all lines intersect at point M then the measure of GML is 65 degrees
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
We know that the vertical angles are equal
And the sum of angles on a line are 180 degrees
So 85+30+x=180
115+x=180
Subtract 115 from both sides
x=180-115
=65 degrees
Hence, if all lines intersect at point M then the measure of GML is 65 degrees

Patrice goes to fishers candy shop with the price of gummy candies modeled by the equation y=5/2x where x is the amount of gummy candy in lbs
Answer:
You need to put the question, but I'll try to help as much as I can without the question. y=5/2x, if you put the amount of gummy candy in lbs in the x's place, and you multiply the amount by 5/2, you will get the price.

Answer:
Step-by-step explanation:
LHS
tan θ * cot θ
= sin θ / cos θ * cos θ / sinθ
= 1
RHS
sec θ * cos θ
= 1/cos θ * cos θ
= 1
Therefore LHS = RHS proved.

A man has Rs 1900. he lent some of it at 5% p.a and rest at9% p.a. The total amount of interest which he got after4 years was Rs 580.Wwhat was the sum
ans= Rs650,Rs 1250
Answer:
The sum is Rs 1,250 and Rs 650
Step-by-step explanation:
Let the amounts be represented as $x and $y
The sum of both is 1900
Thus;
x + y = 1,900 •••••(i)
Mathematically, the interest on the amount borrowed is;
I = PRT/100
where p is the principal, representing the amount borrowed
R is the rate
T is the time
for the first amount of $x ; we have interest as;
I = (x * 5 * 4)/100 = 20x/100
for the second, we have
I = (y * 9 * 4)/100 = 36y/100
The sum of both is 580
Thus;
20x/100 + 36y/100 = 580
20x + 36y = 58000 •••••(ii)
From equation i;
x = 1,900 - y
Substitute this into equation ii
We have this as;
20(1900-y) + 36y = 58,000
38000 - 20y + 36y = 58,000
16y = 58000 - 38000
16y = 20,000
y = 20,000/16
y = 1250
From equation 1;
x + y = 1900
x = 1900-y
x = 1900-1250
y = 650

=356 so it's C
Answer:
C: 356 sq ft.
Step-by-step explanation:
Imagine a rectangle filling the empty space in the polygon.
Using this, we get 440 sq ft.
Now subtract the area that you filled in.
440-(14x6)=A
440-84=A
356=A
A triangle has two sides measuring 8 and 15. The included angle is 33°. What is the length of the side opposite the 33° angle?
Answer:
Measure of the side opposite to the angle measuring 33° is 9.37 unit
Step-by-step explanation:
If a, b and c are the sides of a triangle,
And 'a' = 8
b = 15
Measure of the Included angle C = 33°
By applying cosine rule in the given triangle,
c² = a² + b² - 2abcos(C)
c² = 8² + (15)² - 2(8)(15)cos(33°)
= 64 + 225 - 201.28
= 87.72
c = √87.72
c = 9.266
≈ 9.27
Therefore, measure of the side opposite to the angle measuring 33° is 9.37 units

What is the range of 4,3,3,6,10,7,4,3
Step-by-step explanation:
We have,
3,3,3,4,4,6,7,10
The largest number (L) = 10
The smallest number(S) = 3
Since, the range is the difference between the largest and the smallest value given in the data,
Here,
R = L-S
= 10-3
= 7
Thus Range = 3
