A triangle that has two sides equal is called an Isosceles Triangle.

It is given in the question a triangle ABC

With BA =BC

therefore angle A is equal to angle C

In a triangle the angle opposite to the longest side is the biggest angle

Therefore angle B is the largest angle.

Step-by-step explanation:

For a right triangle, with the information given,   tangent function is most appropo

tan 41 = 4/x re-arrange to

      x = 4 / tan(41)             then x = 4.60

The expression that gives the distance is [tex]\sqrt{(-3 - 6)^2 + (4 + 2)^2}[/tex]

The points are given as:

(-3, 4) and (6, -2)

The distance between two points is calculated using:

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

This gives

[tex]d = \sqrt{(-3 - 6)^2 + (4 + 2)^2}[/tex]

Hence, the expression that gives the distance is [tex]\sqrt{(-3 - 6)^2 + (4 + 2)^2}[/tex]

Based on the information shown through the bar graph, a misrepresentation of the data is that: B. the categories along the horizontal axis are missing one of the days.

A bar graph can be defined as a type of chart that is used for the graphical represent of data (information), especially through rectangular bars or vertical columns.

Based on the information shown through the bar graph in the image attached below, we can logically deduce that a misrepresentation of the data is that the categories along the horizontal axis are missing one of the days (Friday).

In conclusion, this bar graph misrepresented the data because Friday is missing from the categories along the horizontal axis.

Answer:

C

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion , that is

[tex]\frac{RS}{FG}[/tex] = [tex]\frac{ST}{GH}[/tex] ( substitute values )

[tex]\frac{RS}{21}[/tex] = [tex]\frac{4}{12}[/tex] ( cross- multiply )

12 RS = 84 ( divide both sides by 12 )

RS = 7 cm

Based on the difference in the observed means given, we can infer that energy drink does indeed have an effect on performance.

First find the observed mean difference:

= 11.6 - 10.8

= 0.8 seconds

When the exercise is done only once, we see that on average, those who took the energy drink were faster and so finished earlier than those who didn't.

We can therefore infer that the energy drink has an effect on performance.

Answer:

Volume

For the rectangle, h = 3cm, l = 8cm, w = 6cm
V = length x width x height
V = 8cm x 6cm x 3cm
V = 144cm^3

For the semi circle, we need to find the radius. The radius is width/2, so 6cm/2 = 3cm. r = 3cm, [tex]\pi[/tex] = 3.14
V = radius^2 x height x [tex]\pi[/tex]
V = 3cm^2 x 3cm x 3.14
V = 84.8 cm^3/2 (because the cylinder needs to be divided to form a semi-circle)
V= 42.4cm^3 (there are two cylinders though so we will multiply this by 2 in the total volume)

Total volume:
V = 144cm^3 + 42.4cm^3(2)
V = 186.4cm^3

Surface Area

Rectangular prism:
A = 2[w(l) + h(l) + h(w)]
A = 2[6cm(8cm) + 3cm(8cm) + 3cm(6cm)]
A = 180cm^2
But there are two sides that are covered by the semi-circular prisms, so we will have to calculate those sides and remove them.
A = l x w
A = 6cm x 3cm
A = 18cm^2(2) (2 being the two faces)
A = 36cm^2

A = 180cm^2 - 36cm^2
A = 144cm^2 (the area of the rectangle)

Semi-circular prism:
A = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex]r^2
Earlier, we found out that the radius of the circle is 3cm, so we will plug that in.
A = 2(3.14)(3cm)(3cm) + 2(3.14)(3cm)^2
A = 113.09cm^2

Total surface area:
A = 144cm^2 + 133.09cm^2
A = 277.09cm^2

Therefore the total volume of the prism is 186.4cm^3 and the total surface area is 277.09cm^2.

Explanation:

A full circle of radius r = 14 cm has a circumference of...

C = 2pi*r

C = 2*3.14*14

C = 87.92

This is the approximate distance around the circle, aka the perimeter.

Half of this is 87.92/2 = 43.96 which is the curved distance of this semicircle.

The straight line portion is 14+14 = 28 cm long.

The total perimeter of the semicircle shown is 43.96+28 = 71.96 cm

Step-by-step explanation:

no. of students in each group=164/18=9.111111...=10 (nearest 10)

Answer:

8

Step-by-step explanation:

When rounding to the nearest 10:

Therefore:

164 rounded to the nearest 10 = 160

18 rounded to the nearest 10 = 20

To approximate the number of students in each year group, divide the rounded number of students by the rounded number of groups:

⇒ 160 ÷ 20 = 8

The recorded angle measurements of ∠BAC and ∠CAD could be 110° and 70°, vice versa.

Supplementary angles are a pair of angles that always sum up to 180°. These angles can either;

Adjacent supplementary are angles with a common vertex and arm.

Non- adjacent supplementary angles are angles without a common vertex or arm.

∠BAC and ∠CAD are adjacent supplementary angles because they have a common vertex, A, and a common arm AC.

They add up to 180°.

∠ BAC = 110° and ∠CAD = 70°

Hence, the angles could be 110° and 70°.

From the calculation below, the actual difference, if Robert had read the numbers correctly, is 168.

Let X represents the number from which subtrahend is subtracted.

Therefore, we can calculate X as follows:

X – 17 = 222

X = 222 + 17 = 239

If the subtrahend is read correctly as 71 and then subtracted from 239, we have:

Actual difference = 239 – 71

Now,
4.f(x) = 4(1/2 x^2 + 3x) = 4/2 x^2 + 12x = 2x^2 + 12x

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 30 & 100\\ 27& x \end{array} \implies \cfrac{30}{27}=\cfrac{100}{x} \\\\\\ \cfrac{10}{9}=\cfrac{100}{x}\implies 10x=900\implies x=\cfrac{900}{10}\implies x=90[/tex]

Answer:

The value of the angle P and Q are equal which is equal to 36.86°.

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

From Δ it is obtained that;

[tex]\rm cos P = \frac{B}H} \\\\ \rm cos P = \frac{16}{20} \\\\ P=cos^{-1}\frac{16}{20} \\\\ P= 36.86 ^0[/tex]

[tex]\rm sin \ Q = \frac{12}{20} \\\\ Q= sin^{-1}(0.6) \\\\ Q= 36.86^0[/tex]

sin P= sin Q

Hence, the value of the angle P and Q are equal which is equal to 36.86°.
