1. The product of 4, and a number decreased by 7, .is 100. Find the number

Answer:

The value of mEFD = 214°

Step-by-step explanation:

Given that the measure of the degree of one of the central angles of an inner circle is 146°.

We know that sum of all central angles is 360°.

In other words, in our case

mEFD + 146° = 360°

Thus, we can determine the mEFD using the equation

mEFD + 146° = 360°

so subtracting 146° to both sides

mEFD + 146° - 146°  = 360° - 146°

mEFD = 214°

Therefore, the value of mEFD = 214°

Answer:

[tex]y-9=-\frac{3}{7} (x+4)[/tex]

Step-by-step explanation:

Slopes are negative reciprocals when two lines are perpendicular

[tex]m= - \frac {3}{7}[/tex]

Equation of straight line in point-slope form is given as

[tex]y-y_1=m(x-x_2)[/tex]

Here [tex](x_1, y_1)= (-4, 9)[/tex]

[tex]y-9=-\frac{3}{7} (x+4)[/tex]

The equation of line passes through the point (-4, 9) will be;

⇒ y - 9 = - 3/7x - 12/7

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (-4, 9).

And, The perpendicular line is,

⇒ y - 2 = 7/3 (x + 5)

Now,

Since, The equation of line passes through the point (- 4, 9).

So, We need to find the slope of the line.

Since, The product of the slope of perpendicular line is - 1.

Hence, Slope of the perpendicular line is,

⇒ y - 2 = 7/3 (x + 5)

m = dy/dx = 7/3

m = 7/3

Thus, The equation of line with slope - 3/7 is,

⇒ y - 9 = - 3/7 (x - (-4))

⇒ y - 9 = - 3/7 (x + 4)

⇒ y - 9 = - 3/7x - 12/7

⇒ y = - 3/7x + 9 - 12/7

⇒ y = - 3/7x + 51/7

Therefore, The equation of line passes through the point (-4, 9) will be;

⇒ y - 9 = - 3/7x - 12/7

Answer:

A. 60 degrees

Step-by-step explanation:

The sum of the abgles in a triangle is 180°. We are already given 96° and 24°.

so we will subtract the given values from 180 to find the third angle

180-(96+24)=180-120=60°

The answer is A. 60°

A^2+B^2=C^2

Answer:

The sides can be 38 and 24.

Step-by-step explanation:

Consider the provided information.

The given options are: a) 15, b) 24, c)38, d)41, E)53

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Here a=12 and b=28 we need to find c

The sum of 12 and 28 is 40.

So, It means the side can not be 41 and 53 as it is greater than 40.

Now let the third side is 15.

Then the sides are 12, 28  and 15

The sum of two smaller sides: 12+15=27

But 27 is less than 28.

So the side can't be 15.

Now let the third side is 24.

Then the sides are 12, 28  and 24

The sum of two smaller sides: 12+24=36

But 36 is greater than 28.

So the side can be 24.

Now let the third side is 38.

Then the sides are 12, 28 and 38

The sum of two smaller sides: 12+28=40

But 40 is greater than 38.

So the side can be 38.

Hence, the sides can be 38 and 24.

Answer:

272

Step-by-step explanation:

45 and a third = 45 1/3

one sixth = 1/6

hence:

45 and a third divided by one sixth =

= 45 1/3 ÷ 1/6

= 136/3 ÷ 1/6

We convert to multiplication by converting 1/6 to its reciprocal which is 6/1

Hence:

= 136/3 ×6/1

= 272

Step-by-step explanation:

Answer:

1 hour= 45 miles

1/2 hour=22.5 miles

3 hours= 135

Step-by-step explanation:

just work out one hour by halving 90 miles which is 45. Then work out the rest by halving again and multiplying by 3.

Answer:

1st way:

90/2=45

1 hour = 45 miles

45/2=22.5

0.5 hour = 22.5 miles

45+22.5=67.5

1.5 hour = 67.5 miles

67.5x2=135

3 hours = 135 miles

2nd way:

90 miles - 2 hours

1 hour - 60 minutes

60x2=120

90/120=0.75

1 minute - 0.75 miles

0.75x60=45

1 hour = 45 miles

60:2=30

60+30=90

0.75x90=67.5

1.5 hour = 67.5 miles

60x3=180

0.75x180=135

3 hours = 135 miles

Answer:

Step-by-step explanation:

2a+3b+2k= $3.19

3a+4b+2k=$4.12

1a+1b+4k=$3.01

The system of equation that can be used to solve these scenario are          2a + 3b + 2k = 3.19, 0a + 4b + 2k = 4.12 and  1a + 1b + 4k = 3.01.

A linear equation consist of variables and constant sperated by arithmetic operations which has highest degree of 1.

We know that a system of equations is formed when we have two or more than two linear equations in two or more than two variables and a system of equations is consistent when the number of variables is equal to or less than the number of equations.

Given in this questin is 3 variables Applles(a). Bananas(b) and Kiwis(k) and we can form three equations in three variables they are,

2a + 3b + 2k = 3.19...(i)

0a + 4b + 2k = 4.12...(ii)

1a + 1b + 4k = 3.01...(iii)

We can solve this system of equation by first multiplying eqn(iii) by 2 and then subtracting it from eqn(i) to eliminate variable 'a' and then equating with eqn(ii) to eliminate variable 'b' or 'k'

Answer:

8*2^(n-1)

Step-by-step explanation:

This is a geometric sequence since we multiply from the previous term.

a_n = a_1 * common ratio^(n-1) where a_n is the nth number and a_1 is the first.

The first term is 8, so we have

a_n = 8*<common ratio>^(n-1) = 8*2^(n-1)
