Answer:

the answer to your question is -8.5

Answer:

-3.4 × 2.5 = -8.5

Step-by-step explanation:

Since these are short decimals, you can probably convert these into fractions if you'd like.

So -3.4 = -17/5

And 2.5 = 5/2.

So just multiply this like you would multiply two fractions, just multiply across the numerator, and denominator, and then just simplify; numerator × numerator / denominator × denominator.

So

The trick when multiplying by 5 is to divide the number in half, and multiply by 10.

-17/5 × 5/2 = -17 × 5 / 5 × 2 = -17/2 × 10 / 10 = -8.5 × 10/10 = -8.5 × 1 = -8.5

(The tens just cancel and make 1 so you are just left with this answer)

You can also try splitting the decimals up into factors:

-3.4 × 2.5 = (-3 - 0.4)(2 + 0.5) = -6 + -0.8 + -1.5 + 0.2 = -6 + -1 + -1.5 = -7 + -1.5 = -8.5.

Answer:

Yes, unit of the first rate can be be different from and second and still represent the same measurement/value.

Step-by-step explanation:

Yes, if we have two units rate and one rate is converted to another, both measurement will still remain the same even after the conversion but the rate will be different.

For example if we want to convert $2 to naira, note that the unit rates for are distinct but after conversion the amount of both money will be the same.

If $1 = #386

2$ = 2×#386

$2 = #772

Hence the measurement of $2 is equivalent to 386 naira even though the rates are distinct (naira and $)

Answer:

67 degrees

Step-by-step explanation:

It is given that,

The measures of the three angles of a triangle are 43°, 70°, and xº.

We need to find the value of x.

We know that, the sum of angles of a triangle is equal to 180 degrees. Applying this theorem, we get :

[tex]43^{\circ}+70^{\circ}+x^{\circ}=180^{\circ}\\\\113^{\circ}+x^{\circ}=180^{\circ}\\\\x^{\circ}=180^{\circ}-113^{\circ}\\\\x^{\circ}=67^{\circ}[/tex]

Hence, the value of x is 67 degrees.

Answer:

KL = 12

Step-by-step explanation:

Given that L is the midpoint of KM , then

KL = KM , substitute values

2x = x + 6 ( subtract x from both sides )

x = 6

Thus

KL = 2x = 2 × 6 = 12

The measure of the segment KL is 12 units if the L is the midpoint of KM. If KL = 2x and LM = x + 6

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

L is the midpoint of KM. If KL = 2x and LM = x + 6.

Given that L is the midpoint of KM, then

From the question:

KL = KM

2x = x + 6

After simplification:

x = 6

KL = 2x

Plug x = 6 in the above equation:

KL =2(6)

KL = 12

The measure of the segment KL is 12 units.

Thus, the measure of the segment KL is 12 units if the L is the midpoint of KM. If KL = 2x and LM = x + 6.

The Lily is correct because full numbers are not fractions and can be positive, negative, or zero.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we know, the number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56 etc. are the numbers.

Lilly is on point. Integers are full numbers that are not fractions and can be positive, negative, or zero, so she is right.

For example:

1/2 + 1/3 = 5/6

Answer: Because when you divide 25 by 8, the result is greater than 3.

The solution is,  Because when you multiply 25 by 8, the result is less than 3.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

given that,

a capacity of 25 fluid Ounces more than a capacity of 3 cups

we have to find why it is correct.

now, we get,

if we divide 25 by 8

i.e. 25/8

now, we know,

24/8 = 3

so, 25/8 = 3.125

i.e. 25/8 > 3

as, we have, the result is greater than 3.

Hence,  a capacity of 25 fluid Ounces more than a capacity of 3 cups is,

Because when you divide 25 by 8, the result is greater than 3.

Answer:

The probability is 0.18

Step-by-step explanation:

Here, we are interested in calculating a conditional probability;

Let the event that a voter is a Republican be R , the event that a voter is a Democrat be D and that a voter is an independent is I

Let the event that the election issue is favored be F

We have the following probabilities;

P(R) = 46% = 0.46

P(D) = 45% = 0.45

P(I) = 1-0.45-0.46 = 0.09

The conditional probability we want to calculate is;

P(D | F) which can be read as probability of event D given event F

From the question, we can identify the following conditional probabilities;

P(F|R) = 0.46 * 0.5 = 0.23 (0.5 is gotten from 50% = 50/100)

P(F | D) = 0.45 * 0.4 = 0.18

P( F | I) = 0.09 * 0.6 = 0.054

P(F) = 0.054 + 0.18 + 0.23 = 0.464

Mathematically; From Baye’s theorem

P( D | F) ={ P ( F | D) * P(D) }/ P(F)

P( D | F) = (0.18 * 0.45)/0.464 = 0.1745

Answer:

B. Exponential Function; base = 2; initial value = - 3.8

Step-by-step explanation:

hey there,

< The formula for exponential functions is [tex]A_{t} = A_{o} e^{kt}[/tex]. The function given DOES follow this formula (At = y, -3.8 = Ao, e = 2, k = 1, t = x) so that means it is an exponential function. C cannot be the answer.

You already know that e is the base in called the "natural base". e is equal to a number around 2. In this function, they just put it as "2". So we know that the base is equal to 2.

Ao means initial value and At means value after the experiment is done. Here, we can see Ao = -3.8 so that is the initial value.

base = 2; initial value = - 3.8 >

Answer:

The inequality is;

2x + 3y ≤ 30

Step-by-step explanation:

Here, we want to select which of the inequalities represent all possible combinations of x roses and y carnations.

From the question, we are told that roses cost $3 and carnations cost $2

So, by buying x roses, total amount spent = $3x

By buying y carnations, total amount spent = $2y

Now, we are told that she does not want to spend more than $30, this means she can spend less than $30 or exactly $30 but cannot spend more than $30

So, by mathematical convention, we say the sum of the roses and carnations bought is less than or equal to $30

Thus we have;

2x + 3y ≤ 30

2x + 3y ≤ 30

≈ 3927 litres

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = Ah ( A is the area of the base and h the height )

Note that h of oil = 250 ÷ 2 = 125 cm ( since half full )

V = πr²h

   = π × 100² × 125 = 1250000π cm³ ( divide by 1000 )

   = [tex]\frac{1250000\pi }{1000}[/tex] = 1250π litres ≈ 3927 litres ( to the nearest litre )

Answer:

3927

Step-by-step explanation:

first u have to find volume of cylinder its volume is

V=

[tex]\pi \times radius ^{2} \times height[/tex]

so it become 7853981cm^3 then convert it into Liters as you know 1liter=1000cm^3

so divide your volume with 1000 and the answers

is 7853 so as u know that it is half filled than divied ur 7853 by 2 then final ans is 3927
