The

pupils

that prefer

English

as their favorite subject from the table is 26

How to determine the total number

From the table provided, we have to fill the empty spaces before finding the sum of the numbers.

To calculate the

number

of girls that chose

English

= Total number of girls - sum of Mathematics and Sciences

= 38 - (20 + 12)

= 38 - 32 = 6

To calculate the exact number of boys that chose English, we have;

= Total for Mathematics- Girls that chose Mathematics

= 25 - 20 = 5

Also,

To find the

total

pupils for all the courses - total for girls in general

= 70 -38 = 32

Then,

= 32 - ( 5 + 7)

= 32 - 12 = 20

The total pupils that chose English

= 20 + 6

= 26 pupils

Thus, the

number

is 26

Triangles ΔICR and ΔISU are congruent by SAS rule of congruency, therefore; ∠CIR ≅ ∠SIU by CPCTC

Two triangles, ΔABC and ΔXYZ are said to be congruent by the Side-Angle-Side, SAS congruency rule, if the two sides and an included angle of triangle ΔABC, are congruent to two sides and an included angle of triangle ΔXYZ.

The specified measurements are;

∠1 ≅ ∠4

CU = RS

IC = IS

IC ≅ IS (Definition of congruency)

The congruency of the sides IC and IS indicates that the triangle ΔICS is an isosceles triangle

Therefore, ∠2 ≅ ∠3 by the properties of the base angles of an isosceles triangle

CU - RU = RS - RU (subtraction property)

RU ≅ RU, (reflexive property of congruency)

CU - RU = CR

RS - RU = SU

CR = SU (Substitution property)

Answer:

√ − 6 /√ − 6 √ − 7 = -1 + 0i

Step-by-step explanation:

Answer: 1/3 ± √29/3i

Step-by-step explanation:

To solve these equations, move everything to one side:

3x^2-2x+10 = 0

This cannot be factored, so use the quadratic formula:

x = -(-2) ± √( (-2)^2 - 4(3)(10)) / 2

x = (2 ± √4 - 120) / 6

x = 2 ± (√116 • i) / 6

x = 2 ± (2√29•i) / 6

x = 1/3 ± (√29/3)i

Length of NO = 4 unit.

Length is the distance of any object or any figure form one end to another end. In the above question, length of different part of a same straight line is measured one by one.

What is the length of NO given in question?

MP is a straight line. N, M, O, P are all lying on this line. N is between M and O and O is between N and P.

length of MP = 9 unit

length of MO = 6 unit

length of NP = 7 unit

As per the statement, MP - NP = MN

                              MN = 9 - 7

      length of MN = 2 unit

as N is between M and O

so, NO = MO - MN

The required volume of the given figure is 1134 cubic in.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Given that,

A figure made up of two rectangular prisms has shown, we have to determine the volume of the prism.

Here,

The required volume of the figure is given as,

Volume = Volume of the bottom prism + Volume of the top prism

Volume = [7 ×2 × 21 ] + [12 × 10 × 7]

Volume = 294 + 840

Volume = 1134 cubic in.

Thus, the required volume of the given figure is 1134 cubic in.

The sum of all nine integers in the subtraction square is equal to 9 times the number in the top left unit square, which is k.

1.  Fill in the subtraction square with three rows and three columns.

2.  In each row from left to right, and in each column from top to bottom, the first integer minus the second integer equals the third integer.

3.  The sum of all nine integers is equal to the sum of the numbers in each row plus the sum of the numbers in each column.

4.  The sum of the numbers in each row is equal to k + (k - k) + (k - (k - k)) = 3k

The solution for the given inequality (5/7)*c + 2 ≤ 4/7 is the one on the third option:

c ≤ -2

Here we want to solve the following inequality:

(5/7)*c + 2 ≤ 4/7

We want to solve this for the variable c, to do so, we need to isolate that variable.

We can start by subtracting 2 in both sides, so we will get:

(5/7)*c + 2 ≤ 4/7

(5/7)*c +2 - 2 ≤ 4/7 - 2

(5/7)*c ≤ 4/7 - 14/7

(5/7)*c ≤ -10/7

Now we can multiply both sides by 7/5 to get:

(7/5)*(5/7)*c ≤ (-10/7)*(7/5)

c ≤ -10/5

c ≤ -2

When the short leg of a right triangle is 10 meters long and the sharp angles are present, the right triangle's longer leg has a measurement of 21.45 meters.

Right angles are created when two straight lines cross at a 90° angle or are perpendicular to one another at the intersection. The sign stands for a right angle. Different right angle formations can be seen in the above image. The proper angles can be found in shapes. Right triangles are triangles with one of the internal angles at a right angle of 90 degrees. Since a triangle's three interior angles sum up to 180 degrees, a right triangle's three interior angles must always add up to 90 degrees since one of them is always 90 degrees.

given

x / sin 65° = 10 / sin 25°

x = 10 sin 65°/ sin 25°

x = 21 .45 meters

From the question, we have the following parameters that can be used in our computation:

Sequence: 4, 12, 20, 28....

The above sequence is an arithmetic sequence with the following parameters

First term, a = 4

Common difference, d = 8

So, the x-th term is

f(x) = a + (x - 1) * d

Substitute the known values in the above equation, so, we have the following representation

f(x) = 4 + (x - 1) * 8

This gives

f(x) = 8x - 4

So, the equation to plot is f(x) = 8x - 4

B)  7

Step-by-step explanation:

Given information:

If there are 30 students in each class, and there are 4 classes, the total number of students is:

[tex]\begin{aligned}\implies \textsf{Total students}&=\textsf{Students per class} \times \textsf{Number of classes}\\&=\sf 30 \times 4\\&=\sf 120\end{aligned}[/tex]

Therefore, the total number of people going on the trip is:

[tex]\begin{aligned}\implies \textsf{Total number of people}&=\sf Students+Teachers+Parents\\&=\sf 120+6+14\\&=\sf 140\end{aligned}[/tex]

As there are 20 seats in each row at the theater, to calculate how many rows should be reserved for the trip, divide the total number of people by the number of seats per row:

[tex]\begin{aligned}\implies \textsf{Rows to reserve}&=\sf \dfrac{\sf Total\;people}{\sf Seats\;per\;row}\\\\&=\sf\dfrac{140}{20}\\\\&=\sf 7\end{aligned}[/tex]

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The sequence is,

⇒ 0.4, 0.2, 0.6, 0.4, 1.2, 1.0, 3.0, .., .., ...,

Now,

Since, The sequence is,

⇒ 0.4, 0.2, 0.6, 0.4, 1.2, 1.0, 3.0, .., .., ...,

Clearly, The pattern of the sequence is,

⇒ 0.4 - 0.2 = 0.2

⇒ 0.2 × 3 = 0.6

⇒ 0.6 - 0.2 - 0.4

⇒ 0.4 × 3 = 1.2

⇒ 1.2 - 0.2 = 1.0

⇒ 1.0 × 3 = 3.0

⇒ 3.0 - 0.2 = 2.8

⇒ 2.8 × 3 = 8.4

⇒ 8.4 - 0.2 = 8.2
