The digit 3 in 5,630, is not 10 times the value of the digit 3 in 342. It's false.

It should be noted the question has to do with place value. In this case, the digit 3 in 5,630 gives a value of 30.

On the other hand, the digit 3 in 342 is 300.

Therefore, we can see that the digit 3 in 5,630, is not 10 times the value of the digit 3 in 342.

Therefore, the correct option is false.

The value of the line segment TU is 12 units.

A line segment is a fixed-length section of the a line to two ends.

According to the question;

TU = x + 8 and ST = 3x are the lengths.

SU is the total length of the line segment.

Now, it is clear that SU is divided into parts such that;

SU = ST + TU

As, T is the mid point of the line SU;

The,

ST = TU

Equating the values;

3x = x + 8

Solving the equation;

3x -x = 8

x = 4

Put the value of x in TU;

TU = x + 8

TU = 4 + 8

TU = 12

Therefore, the value of the line segment TU is found as 12 units.

The equation with nontrivial linear combination is (16)4x + ( -48 )2x²+ (-8 )(8x-12x²) = 0

We can solve this problem following some steps.

Let's assume the value is A for blank one and it is B for blank two.

Now we can rewrite the equation as,

(16)4x + (A) 2x²+ (B)(8x-12x²) = 0

Or, 64x + 2Ax² + 8Bx - 12Bx² = 0

After rearrangement, we can write this equation as,

x ( 64 + 8B) + x²( 2A - 12B) = 0

We can consider the whole equation as zero, only when the coefficient of both x and x² is zero, To complete a nontrivial combination, we have to write,

∴ ( 64 + 8B) = 0 [ Coefficient of x ]

Or , 8B = -64

Or, B = -64/8 = -8

Again following the previous concept we can also write, ( 2A - 12B ) = 0

[ Coefficient of x² ]

Now, we should put the value of B = -8

∵ ( 2A - 12B ) = 0

Or, 2A + 96 = 0

Or, 2A = - 96

Or, A = - 48

So, the value of A is -48, and the value of B is -8

Now we can conclude,

(16)4x + ( -48 )2x²+ ( -8 )(8x-12x²) = 0

Answer: an=2(n-1)+1

Step-by-step explanation:

1,3,5,7, …

As the terms progress in the sequence, each term get increased by 2 to get to the next term. Hence, the change is linear and can be modeled with the function y=2(x-1)+1 where y=term value, x=term number and 1 is the first term in the sequence.

y=2(x-1)+1

an=2(n-1)+1 ==> n=term number while an=term value. an=nth term

The value of the x in the linear equation is a 3/4.

According to the statement

We have to find that the value of the x.

So, For this purpose, we know that the

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.

From the given information:

8 - (6 - 8x) = 4x + 5

Now we have to solve this

Then

8 - (6 - 8x) = 4x + 5

8 - 6 + 8x = 4x + 5

Now, rearrange the above written terms for the value of the x

2 + 8x = 4x + 5

4x = 3

x =3/4.

So, The value of the x in the linear equation is a 3/4.

to solve this you must first find her rate

6 / 20 is her rate

you want to know how many she can do in ten minutes so we must find how many seconds are in 10 minutes

10 * 60 = 600

175 / 600 is the rate needed fro the test

Answer:

A = 80

B = 10

Step-by-step explanation:

a + b = 90

a = 8b

above are  the two equations that we will used to find A and B.

substitute in 8b for a in the first equation.

a + b = 90

8b + b = 90  Combine like terms

9b = 90  Divide both sides by 9

b = 10

If b is 10, than a must be 80.

Gradient: 9

Y-intercept: -2

Step-by-step explanation:

The equation of a line is expressed in this format:

y = mx + c

Where m is the gradient (slope) of the line, and c is the y intercept.

The equation in the question is already in this format, meaning the values can be read directly from it without needing any rearranging.

m = 9, c = -2.

Answer: 29 feet

Step-by-step explanation:

A light bulb will consume 3,600 watts - hours in 1 day if it consumes 12,600 watts in 3 days 12 hours.

We are given that:

Consumption in 3 days 12 hours = 12,600 watts

12 hours = 12 / 24 days = 0.5 days

Days = 3 + 0.5 days = 3.5 days

Now, by using the unitary method, we get that the consumption by a light bulb in 1 day will be equal to:

3.5 days = 12,600 watts

1 day = 12,600 / 3.5 watts

1 day = 3,600 watts

Therefore, a light bulb will consume 3,600 watt - hours in 1 day if it consumes 12,600 watts in 3 days 12 hours.

The smallest angle on the line will be 36°

A line segment seems to be a straight line that connects two places. A line segment does indeed have a predetermined length. A ruler can be used to determine the shortest distance between the two points.

A straight angle in geometry is an angle with a vertex point of 180 degrees. It basically generates a straight line with sides that point in opposite directions first from the vertex. It is also known as "flat angles."

We know the the sum of the straight angle is = 180°

So,

(5a + 18) + (48 - a) + (8a -30 ) = 180°

5a - a + 8a + 18 +48 - 30 = 180°

12a + 36 = 180°

12a = 180 - 36

a = 12°

So putting the value of a in the equation:

(5a + 18) = 5 *12 + 18 = 78°

(48 - a) = 48 - 12 = 36°

(8a -30 ) =  96 - 30 = 66°

36° < 66° <78°

So the smallest angle on the line will be 36°

Probability is used to determine the odds that a random event would happen. The probability the event happens is 1 and the probability that the event does not happen is 0.

The more likely the event is to occur, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

The probability of picking a dime and then a penny without replacement = (number of dimes / total number of coins) x (number of pennies / total number of coins - 1)

The x-intercepts of the parabola are  (-1,0) and (-5,0) and the coordinates of the vertex are  ( -3 , - 4 ).

A parabola is a graphical representation of a function of the form y=g(x) where g(x) is a quadratic polynomial of x.

The given equation of the parabola is y = x² + 6x + 5

to find the x-intercepts we have to take the value of y at zero.

∴  x² + 6x + 5 = 0

or,  x² + 5x + x + 5 = 0

or, x (x + 5) + 1 ( x + 5 ) = 0

or, (x+5)(x+1)=0

either x=-5 or x=-1

Therefore the x-intercepts of the graph is (-1,0) and (-5,0)

Now to find the vertex of the parabola:

y =  x² + 6x + 5

or, y = x² + 2·x·3 + 3² - 4

or, y = (x + 3)² - 4

Therefore from the above equation we can say that the vertex of the parabola is at ( -3 , - 4 ).
