plz help me asap I just need to know the equation also it can be A) or C)

Answer:

-69

Step-by-step explanation:

inches:-69

-5 9/12 (-5 3/4 clearer) feet

Explanation in detail:

Write the equation down and distribute it.

3x - 1 = 2(x + 34)

3x - 1 = 2x + 68

Remove the variable on one side first (it makes solving the equation less complicated.)

3x - 1 = 2x + 68

-3x -3x

-1 = -x + 68

On all sides, subtract 68.

-1 = -x + 68

-68 -68

-69 = x

I'm guessing the answer in feet and inches is...

inches:-69

-5 9/12 (-5 3/4 simplified) feet

Answer

1242

Explanation

Given: 3% of 4.14 × 10⁴

3% of 4.14 × 10⁴ becomes

3 percent of the given number is 1242.

Given that, 3% of 4.14×10⁴.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here, 3% of 4.14×10⁴ can be written as

3/100 ×4.14×10000

= (3×4.14×10000)/100

= 3×4.14×100

= 1242

Therefore, 3 percent of the given number is 1242.

Answer:

Area of the trapezium = 30 \(cm^{2}\)

Step-by-step explanation:

a = 14

b = 4

h= 5

Area of trapezium =  \(\frac{1}{2} }\)  ( a + b) h = \(\frac{1}{2}\) (14+4) 5

= \(\frac{1}{2}\) x 18 x 5 = 6 x 5 [I solved  \(\frac{1}{2}\) and 18]

If (x,y) is a solution to equations y = x²  and  2y+6 = 2(x+3) , then the value of xy is (a) 1  .

The values of x and y are solutions to two equations:

⇒ y = x²   ....equation(1)

⇒ 2y + 6 = 2(x + 3)    ....equation(2)

To find the value of xy, we first need to find the values of x and y which satisfy both equations.

We can put value of y from the equation(1) into the equation(2) :

⇒ 2y + 6 = 2(x + 3)

⇒ 2x² + 6 = 2(x + 3)

⇒ 2x² + 6 = 2x + 6

⇒ 2x² - 2x = 0

⇒ 2x(x - 1) = 0

that means either "2x=0"   or "x-1=0" ;

⇒   x = 0  or x = 1 .

when x = 1  , we have y = (1)² = 1 .

So , the product is = 1 × 1 = 1 .

Therefore , the value of xy is (a) 1  .

The given question is incomplete , the complete question is

If (x,y) is a solution to equations y = x²  and  2y+6 = 2(x+3) , what is the value of  xy ?

(a) 1

Answer:

4x-3

Step-by-step explanation:

(7x-5) - (3x-2)

aka

(7x-5)  -1 (3x-2)

first distribute the -1 into (3x-2)

-3x+2

so

(7x-5)+ -3x+2

next combine like terms

7x-3x=4x

so

4x-5+2

then

-5+2=-3

so

Answer:

Is not the answer but is how to do it. Sorry

Step-by-step explanation:

you got the value of a=2

use the formula

S=n/2 [2a+(n-1)d] then calculate d from here..

put it in t=a+(n-1)d

The requreid 8th term in the series is 366, which is an option (C).

Arithmetic progression is the series of numbers that have common differences between adjacent values

We can use the formula for the sum of an arithmetic series, which is:

S = n/2 * (a + l)

Since we are given that the first term is 2, we can write the formula for the sum of the first 8 terms as:

1472 = 8/2 * (2 + l)

1472 = 4 * (2 + l)

368 = 2 + l

l = 366

Therefore, the 8th term in the series is 366, which is an option (C).

:According to the question:You are working with a population of crickets. Before the mating season you check to make sure that the population is in Hardy-Weinberg equilibrium, and you find that the population is in equilibrium.

During the mating season you observe that individuals in the population will only mate with others of the same genotype (for example Dd individuals will only mate with Dd individuals). There are only two alleles at this locus ( D is dominant, d is recessive), and you have determined the frequency of the D allele =0.6 in this population. Selection acts against homozygous dominant individuals and their survivorship per generation is 80%. After one generation the frequency of DD individuals will decrease in the population.

According to the Hardy-Weinberg equilibrium equation p² + 2pq + q² = 1, the frequency of D (p) and d (q) alleles are:p + q = 1Thus, the frequency of q is 0.4. Here are the calculations for the Hardy-Weinberg equilibrium:p² + 2pq + q² = 1(0.6)² + 2(0.6)(0.4) + (0.4)² = 1After simplifying, it becomes:0.36 + 0.48 + 0.16 = 1This means that the population is in Hardy-Weinberg equilibrium. This is confirmed as the frequencies of DD, Dd, and dd genotypes

Answer:

111

Step-by-step explanation:

You know the angle missing in the triangle is 69 (180-75-36). The angle on a line is 180. So 180-69=111.

OR

Add the two given angles to get 111 as 75+36+(180-x)=180 so if you subract (180-x) it leaves 75+36.

Parabola equation , characteristic points

Vertex is the point of minimum-max value

A Directrix is a line outside parabola

Vertex is at (x,y) = (4,-5)

Parabola equation in general is

(x-h)^2 = 4•c•(y-k)

here c = -9

and (h,k) = (4,-5)

Then

(x-4)^2 = 4•(-9) •(y+5) = (-36)•(y+5)

(x-4)^2 = (-36)•(y+5)

Now divide by (-36)

-0.06((x-4)^2 = y + 5

-0.06(x-4)^2 - 5 = y

Looking at options, right answer comes to be D) , last option

The sum of the measures of the angle of a triangle is 180 degrees.

The given triangle is a type of triangle and the type of triangle a scalene triangle.

For a scalene triangle, the measure of the three sides are unequal and the sum of the interior angle of a triangle is 180 degrees.

Hence the measure of the angles <A, <B and <C are all less than 90 degrees since they are all acute angles.

We can therefore conclude that:

m<A + m<B + m<C = 180 degrees

When you solve an equation for one variable and then substitute the resulting expression in for that variable in the other equation This is known as the  substitution method.

Describe the substitution formula?

In algebra, substitution refers to replacing the variables' (expression's) letters with their corresponding numerical values. The expression's overall value can then be calculated.

What is substitution in math definition?

The algebraic technique for resolving multiple linear equations at once is called the substitution method. As implied by the name, this strategy involves replacing a variable's value from one equation with another.

                            A technique for resolving systems of equations that entails figuring out the answer for one variable before locating the other.

Since no two sides of the triangle are the same lenght, it is not an isoceles triangle.

Since no angle in the triangle is greater than 90°, it is not obtuse. This means it is acute.

No angle measures 90°, so it isn't a right triangle.

Once again, the sides are all different lenghts, so it is not equilateral.
