Answer:
D
Step-by-step explanation:
Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle. Therefore, option D is the correct answer.
What is an acute angle?An acute angle is an angle that is less than 90°, and these angles can be measured using a protractor.
Triangles can be classified on the basis of angles and sides. An acute triangle is one that is classified on the basis of the measurement of angles. If all the interior angles of a triangle are less than 90°, then the triangle is said to be an acute triangle.
In equilateral triangle all three angles are equal, that is 60°.
Therefore, option D is the correct answer.

5(2x+1)^2+6=26 cant figure this out!!
Answer:
x=1/2 and x=-3/2
Step-by-step explanation:
5(2x+1)^2+6=26
5(2x+1)^2=20
(2x+1)^2=4
2x+1=±2
Now make two equations and solve both for x:
2x+1=2
2x=1
x1=1/2

Suppose that Theta is an angle in standard position whose terminal side intersects with the unit circle at (21/29,20/29). Fine the exact values of cscTheta, cosTheta, and cotTheta
Answer:
The coordinates of the vertex is:
x = 21/29, y = 20/29Horizontal leg = x, vertical leg = 20/29, hypotenuse = 1 (radius of unit circle)
csc θ = hypotenuse / opposite = 1 / (20/29) = 29/20 cos θ = adjacent / hypotenuse = (21/29) / 1 = 21/29cot θ = adjacent / opposite = (21/29) / (20/29) = 21/20Look at the drawings of two cylinders filled to the same level with water. The cylinders are identical in size and shape. Also shown at the right are two marbles, one glass and one steel. The marbles are the same size but the steel one is much heavier than the glass one. When the glass marble is put into Cylinder 1 it sinks to the bottom and the water level rises to the 6th mark. If we put the steel marble into Cylinder 2, the water will rise *
a. to the same level as it did in Cylinder 1
b. to a higher level than it did in Cylinder 1
c. to a lower level than it did in Cylinder 1
The density of a substance is its ratio of its mass to its volume. This determines the mass of the substance. The appropriate option to the question is:
b. to a higher level than it did in Cylinder 1.
The density of a mass determines the volume of liquid that would be displaced when put in a liquid. This is known as the Archimedes principle. It relates the mass of a material to its volume.
The density of the steel marble is more than that of the glass, thus it is expected that the liquid should rise above that of cylinder 1. Because the steel marble would displace more volume of water than the glass marble.
The given cylinders have equal measures and size, and contains the same volume of water. Thus, the water should rise to a higher point compared to that of cylinder 1.
Therefore the required answer is: b. to a higher level than it did in Cylinder 1.

Step-by-step explanation:
This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]. This equals 2, and since a and b are congruent both a and b equal 2.

Answer:
The surface area of the triangular prism is approximately 401.582 square feet.
Step-by-step explanation:
The figure represents a triangular prism, the procedure for calculating the surface area of the entire figure consists in adding the areas of each face (3 rectangles and 2 triangles):
[tex]A = 2\cdot \left[\frac{1}{2}\cdot (9\,ft)\cdot (4\,ft)\right] + (16\,ft)\cdot (4\,ft) + (9\,ft)\cdot (16\,ft) + (16\,ft)\cdot \sqrt{(9\,ft)^{2}+(4\,ft)^{2}}[/tex][tex]A \approx 401.582\,ft^{2}[/tex]
The surface area of the triangular prism is approximately 401.582 square feet.

Trigonometry!!
==========================================================
Explanation:
We are told that quadrilateral ABCD is similar to quadrilateral EFGH.
The order of the four letter sequence is important.
For ABCD, we have AB as the first pair of letters. For EFGH, we have EF as the first pair of letters.Therefore, AB and EF are corresponding sides.
So AB = 10 and EF = x pair up together. We can form the ratio AB/EF which becomes 10/x.
The diagram shows that AD = 8. Notice that A and D are the first and last letters of ABCD. The first and last letters of EFGH are E and H. We can see that AD and EH correspond to one another because of this.
AD = 8 and EH = 6 forming the ratio AD/EH = 8/6
Because the quadrilaterals are similar, the corresponding ratios must be the same. Therefore, AB/EF is the same as AD/EH.
-----------------------
Let's set up a proportion to solve for x
AB/EF = AD/EH
10/x = 8/6
10*6 = x*8
60 = 8x
8x = 60
x = 60/8
x = 7.5 Answer is choice D

Answer:
£27.50
Step-by-step explanation:
The general approach is ...
find the area to be paintedfigure the amount of paint requireddetermine the discounted cost of the paint1. The area to be painted will be the area of the four walls, less the area of the door (which is assumed to be a hole in the wall, so is not painted).
Each wall has the same dimensions, so the same area. The area of the rectangular wall is ...
A = LW
A = (3.5 m)(2.6 m) = 9.1 m²
The area of the door is ...
A = (2.2 m)(0.8 m) = 1.76 m²
Then the area to be painted is the area of the 4 walls less the area of the door:
painted area = 4(9.1 m²) -1.76 m² = 34.64 m²
__
2. Each 2 L tin of paint will cover (2 L)×(8 m²/L) = 16 m², so the number of tins needed is ...
(34.64 m²)/(16 m²/tin) = 2.165 tins
We assume this means Aisha will need to purchase 3 tins, since she will need more paint than is provided by 2 tins.
__
3. Because of the price offer on the paint, Aisha will pay full price for the first two tins, half price for the 3rd tin. That is, she will pay 2 1/2 times the full price of a tin when she buys the 3 tins of paint she needs. Each tin costs £11, so Aisha will pay ...
(2 1/2)(£11) = £27.50
Aisha will pay £27.50 for the paint to paint her living room.

2/5 × 5/8
2× 5/ 5 × 8
= 10/40
=1/4
Answer:
1/4
Step-by-step explanation:
You would do 2/5 times 5/8 which would equal 10/40 cause 5 times 2 is 10 and then 5 times 8 is 40 and then you would simplify the fraction 10/40 which would make it 1/4
