How much carpet would be needed to cover the area in the figure?
Answer:
28 square yards
Step-by-step explanation:
Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number. The figure is not drawn to scale.
Answer:
Lateral Surface Area = 472 m²
Total Surface Area = 486m²
Step-by-step explanation:
The above prism is a Triangular prism
a) Lateral Surface Area = Perimeter of the Base × H
H = 29m
Perimeter of the Base = (7m + 7.28m + 2m)
= 16.28m
Lateral Surface Area = 16.28m × 29m
= 472.12 m²
Approximately to the nearest whole number = 472 m²
b) Total Surface Area
Triangular prism =
2 Triangles and 3 Rectangles
1st Triangle = 1/2 × base × Height
= 1/2 × 2m × 7m
= 7m²
2nd Triangle = 1/2 × base × height
= 1/2 × 2m × 7m
= 7m²
1st Rectangle = Length × Width
= 29m × 2m = 58m²
2nd Rectangle =
Length × Width
= 29m × 7.28m = 211.12m²
Length × Width
= 29m × 7m = 203m²
Total surface area = 7m² + 7m² + 58m² + 211.12m² + 203m²
= 486.12m²
Approximately to the nearest whole number = 486 m²
Option A is the correct option

For #2-7, decide if the triangles in each pair are similar. If they are similar, state how you know they are similar and then complete the similarity statement. If they are not similar, explain why.
Answer:
2. The ratio of the corresponding sides of ΔUTS and ΔUDE are not equal
3. ΔCBA ~ ΔHGF
4. ΔVUT ~ ΔVML
5. ΔTUV ~ ΔJKL
6. The ratio of all the corresponding sides and all the corresponding angles in triangles ΔSTU and ΔSCB are not equal
7. The ratio of the corresponding sides of triangles, ΔKLM and ΔKBC are not equal
Step-by-step explanation:
2. The ratio of the corresponding sides of ΔUTS and ΔUDE are;
36/43, 16/39, and 16/40
We have;
[tex]\dfrac{36}{43} \neq\dfrac{16}{39}[/tex]
∴ ΔUTS is not similar to ΔUDE, because the ration of the corresponding sides of both triangles are not equal
3. The interior angles of ΔCBA are;
∠A = 33°, ∠B = 88°, and ∠C = 59°
The interior angles of ΔHFG are;
∠H = 33°, ∠F = 59°, and ∠G = 88°
∴ ΔCBA ~ ΔHGF (ΔCBA is similar to ΔHGF) (Letters rearranged) by Angle-Angle, AA, similarity postulate
4. The measure of angle ∠LMV = 25° = The measure of angle ∠UTV Given
The measure of angle ∠MVL = ∠TVU by reflexive property
Therefore, ΔVUT ~ ΔVML (ΔVUT is similar to ΔVML) by Angle-Angle, AA, similarity postulate
5. The measure of angles ∠T and ∠U in triangle ΔTUV are equal to the measure of angles ∠J and ∠K in triangle ΔJKL
Therefore, ΔTUV ~ ΔJKL (ΔTUV is similar to ΔJKL) by Angle-Angle, AA, similarity postulate
6. In triangles ΔSTU and ΔSCB, we have;
The ∠TSU = ∠TSU by reflexive property
However, ∠SUT ≠ ∠SNC ≠ ∠STU
Therefore, ΔSTU is not similar to ΔSCB due to the triangles have one non equal angle
[tex]\dfrac{SB}{SU} =\dfrac{22}{33} = \dfrac{2}{3} =\dfrac{18}{27} = \dfrac{CB}{TU} \neq \dfrac{21}{30} = \dfrac{7}{10} = \dfrac{CS}{TS}[/tex]
From which we get;
[tex]\dfrac{SB}{SU} \neq \dfrac{CS}{TS}[/tex]
∴ ΔSTU is not similar to ΔSCB, because not all the ratio of the corresponding sides and angles are equal
7. The ratio of the corresponding sides of triangles, ΔKLM and ΔKBC are;
[tex]\dfrac{KB}{KL} = \dfrac{18}{88} = \dfrac{9}{44}[/tex]
KM = KC + CM = 25 + 107 = 132
[tex]\dfrac{KC}{KM} = \dfrac{25}{132}[/tex]
Therefore;
[tex]\dfrac{KB}{KL} \neq \dfrac{KC}{KM}[/tex]
The ratio of the sides of triangles, ΔKLM and ΔKBC are;
Therefore ΔKLM and ΔKBC are not similar, because the ratio of the corresponding sides are not equal

5x = 180° - 100°
5x = 80°

what is the current world record for solving a rubiks cube 3x3
A cube has square sides with area x2 +24x + 144. What expression represents the surface area of the cube?
Given:
A cube has square sides with area [tex]x^2+24x+144[/tex].
To find:
The expression that represents the surface area of the cube.
Solution:
We have
The area of each side of cube = [tex]x^2+24x+144[/tex]
Number of sides of a cube = 6
We know that, the total surface area of the cube is the product of number of sides of the cube and the area of each side. So, the total surface area of the cube is
[tex]SA=6(x^2+24x+144)[/tex]
[tex]SA=6(x^2)+6(24x)+6(144)[/tex]
[tex]SA=6x^2+144x+864[/tex]
Hence, the expression that represents the surface area of the cube is [tex]6x^2+144x+864[/tex].

A parabola can be represented by the equation x2 = –20y.
What are the coordinates of the focus of the parabola?
(–5,0)
(5,0)
(0,5)
(0,–5)
Answer:
(0, - 5)
Step-by-step explanation:
For a quadratic equation:
y = a*x^2 + b*x + c
if the vertex is at:
(h, k)
Then the focus is at:
(h, k + 1/(4*a))
Here we have the parabola:
x^2 = -20*y
if we isolate y, we get:
y = (-1/20)*x^2
First, we need to find the vertex.
remember that for a general quadratic equation
a*x^2 + b*x + c = 0
the x-value of the vertex is at:
x = -b/2*a
in this case we have b = 0, then our vertex is at x = 0.
If we evaluate the function at x = 0 we get:
y = (-1/20)*0^2 = 0
Then the vertex is at (0, 0)
Thus the focus will be at:
(0, 0 + 1/(4*a))
and we have
a = -1/20
then:
1/(4*a) = -20/4 = 5
Then the focus is:
(0, 0 -5) = (0, - 5)
Answer:
(0,-5)

Ariana rode the bus 5 3/8 miles to the mall. Then she got back on the bus and ride 2 3/4 miles to her friends house and then another 6 1/12 miles back to her house. What is the total distance, in miles that ariana rode the bus
Answer:
14 5/24
Step-by-step explanation:
Ariana's rode the bus 5 3/8 miles to the mall
She rode 2 3/4 miles to her friends place
Then she rode anrhe 6 1/12 miles back home
Therefore the total distance can be calculated as follows
= 43/8 +11/4 + 73/12
= 5456/384
= 341/24
= 14 5/24
Hence the total distance is 14 5/24 miles

Which formula can be used to describe the sequence?
f(x + 1) = Three-fourthsf(x)
f(x + 1) = Negative three-fourthsf(x)
f(x) = Three-fourthsf(x + 1)
f(x) = Negative three-fourthsf(x + 1)
Answer:
f(x + 1) = -(3/4)*f(x)
(second option)
Step-by-step explanation:
Here we have the sequence:
64, -48, 36, -27, ...
First, we can notice two things:
Each term has a different sign than the previous term, so the relation is something like:
f(x + 1) = -k*f(x)
Now to find the value of k, we can just replace some of the values (for example, the first and the second one)
-48 = -k*64
48/64 = k
3/4 = k
Now, if we use any pair of consecutive terms we should get the same value of k, now let's try to use the second and third terms to see if we get the same value of k:
36 = -k*(-48)
36 = k*48
36/48 = k
3/4 = k
We got the same value, so we can conclude that k = (3/4)
Then the relation that describes this sequence is:
f(x + 1) = -(3/4)*f(x)

Need help with this question
Answer:
C
Step-by-step explanation:
In a right triangle, the side opposite the right angle is the largest side as the right angle represents the largest angle in the triangle. Therefore, as 17.5 is opposite the right angle, we can say that AB²+10²=17.5², and √(17.5²-10²)=AB = 14.4
Using sohcahtoa, we can establish that
sin(∠C) = opposite/hypotenuse = 14.4/17.5, and
arcsin(14.4/17.5) = ∠C = 55°
Because the angles in a right triangle add up to 180 degrees, we can say that ∠A+∠B+∠C = 180°, so ∠A + 90 + 55 = 180 and ∠A = 35°

WZ=4cm
Answer:
See below.
Step-by-step explanation:
In a rhombus, all sides are congruent.
In a rhombus, opposite angles are congruent, and consecutive angles are supplementary.
XW = 4 cm
WZ = 4 cm
ZY = 4 cm
YX = 4 cm
m<X = 100 deg
m<Z = 100 deg

if two polygons are similar, what is the length of SR
A. 13
B. 15
C. 28
D. 32
Answer:
SR = 28
Step-by-step explanation:
Recall: The corresponding side lengths of any two similar polygons are proportional.
Since the two polygons given are similar, it implies that:
SR/DC = PQ/AB
SR = ?
DC = 20
PQ = 21
AB = 15
Plug in the values
SR/20 = 21/15
Solve for SR. Cross multiply
SR*15 = 21*20
SR*15 = 420
Divide both sides by 15
SR = 420/15
SR = 28

Answer:
chese
Step-by-step explanation:
Cheese is a dairy product, derived from milk and produced in wide ranges of flavors, textures and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep. During production, the milk is usually acidified and the enzymes of rennet (or bacterial enzymes with similar activity) are added to cause the milk proteins (casein) to coagulate. The solids (curd) are separated from the liquid (whey) and pressed into final form.[1] Some cheeses have aromatic molds on the rind, the outer layer, or throughout. Most cheeses melt at cooking temperature.

A.2yrs
B.5yrs
C.12yrs
D. The debt will never be completely repaid.
Answer:
The correct answer is D. The debt will never be completely repaid.
Step-by-step explanation:
Since the question refers to a credit card debt on which the minimum monthly payment is paid for an indefinite period of months, in this case the debt will never be fully repaid, since the minimum payments will be constantly added values as interest, which will increase the value of the debt due to compound interest.
