What is 9+10???????????

Answer:

2

Step-by-step explanation:

First, find h(-4) by plugging in -4 as x in the function:

h(x) = x + 4

h(-4) = -4 + 4

h(-4) = 0

Then, add 2 to this:

0 + 2

= 2

So, h(-4) + 2 = 2

Answer:

9 weeks

Step-by-step explanation:

edge 2020

On solving the inequality, 9 weeks of exercise are necessary to lower the individual’s resting heart rate below 70 beats per minute.

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

[tex]-0.1x^{3} + 0.6x^{2} +85 < 70\\[/tex]

where, x is the number of weeks of exercise is necessary to lower the individual's resting heart rate below 70 beats per minute.

This cubic inequality can be solved by hit and trial method.

when x = 7.

[tex]-0.1x^{3} + 0.6x^{2} +85 < 70\\[/tex]

[tex]=-0.1*7^{3} + 0.6*7^{2} +85[/tex] = 80.1

80.1 > 70

Thus, x = 7 is not suitable.

when x = 8.

[tex]-0.1x^{3} + 0.6x^{2} +85 < 70\\[/tex]

[tex]=-0.1*8^{3} + 0.6*8^{2} +85[/tex] = 72.2

72.2 > 70

Thus, x = 8 is not suitable.

when x = 9.

[tex]-0.1x^{3} + 0.6x^{2} +85 < 70\\[/tex]

[tex]=-0.1*9^{3} + 0.6*9^{2} +85[/tex] = 60.7

60.7 < 70

Thus, x = 9 is suitable.

Answer: C. 60

Step-by-step explanation:

In this situation, they are asking  the least common multiple of 4,5, and 6.

Find the LCM of the numbers or the multiples of the numbers.

Multiples of 4 are  4, 8, 12,16, 20, 24,28,32,36, 40, 44,48,52,56,60.

Multiples of 5 are  5, 10,15,20,25,30,35,40,45,50,55,60.

Multiples of 6 are  6,12,18,24,30,36, 42, 48, 54, 60,

As we can see in their multiples, they do not share the multiple 6 or 30 .

But they all share the number 60 which means that 60  is the least possilbe number of candies in the bag.

Note that is can go on to be 90 or 120 but they are not the smallest ones.

Answer:

m<EFG = [tex]69^{o}[/tex], and m<GFH = [tex]111^{o}[/tex]

Step-by-step explanation:

Linear pair angles are two supplementary angles.

Thus,

m<EFG + m<GFH = [tex]180^{o}[/tex]

2n + 21 + 4n + 15 = [tex]180^{o}[/tex]

collecting like terms, we have:

6n + 36 = [tex]180^{o}[/tex]

6n = [tex]180^{o}[/tex] - 36

6n = [tex]144^{o}[/tex]

divide both both sides by 6,

n = [tex]24^{o}[/tex]

Therefore,

m<EFG = 2n + 21

            = 2 x [tex]24^{o}[/tex] + 21

            = 48 + 21

            = [tex]69^{o}[/tex]

m<GFH = 4n + 15

             = 4 x [tex]24^{o}[/tex] + 15

            = 96 + 15

            = [tex]111^{o}[/tex]

Thus m<EFG = [tex]69^{o}[/tex], and m<GFH = [tex]111^{o}[/tex]

Answer: kindly check explanation

Step-by-step explanation:

Given the following statements :

A.) To find 49 times 73. I multiply 73 times 50 and take off one group of 73

To obtain the product of (49 and 73)

(73 * 50) - 73

3650 - 73

= 3577

B.) To find 15 times 16, I double 15 and halve 16 and then multiply

Double 15 = (15 * 2) = 30

Halve 16 = (16 / 2) = 8 ;

Then multiply:

(30 * 8) = 240

Similarly ;

(15 × 2) × (16 / 2) = 240

Answer:

Option A

..............................................................

ΔABC ≅ ΔFDE by SAS congruence rule.

The correct option is (1).

Congruence is a phrase used frequently in mathematics to refer to a harmonious connection, comprehension, or correlation. A geometric figure is said to be congruent or to be in the relation of congruence if it is feasible to superimpose it on another so that their whole surfaces match. Two triangles are said to be congruent when two sides and their included angles in one triangle are equal to two sides and their included angles in the other.

As per the given data:

In ΔABC :

∠A = 63°

AC = 2.2

In ΔFED :

∠F = 63°

FE = 2.2

By using the distance formula, we can find AB and FD.

From the coordinates, as we can see in the diagram

FD = [tex]\sqrt{(1 - 1)^2 + (4 - 2)^2}[/tex]

= 2 units

Similarly,

AB = [tex]\sqrt{(5 - 5)^2 + (1 - 3)^2}[/tex]

= 2 units

Now from SAS congruence rule:

AB = FD (Both are 2 units)

∠A = ∠F (given)

AC = FE (given)

Hence, ΔABC ≅ ΔFDE by SAS congruence rule.

Answer:

The 2 numbers are 42 and 91.

Step-by-step explanation:

Let one number be x, then the other is 133-x.

So as the difference is 49 we have:

133 - x - x = 49

-2x = 49 - 133

-2x = -84

x = -84/-2 = 42.

The numbers are 42 and 133 - 42 = 91.

Answer:

let the numbers be x and y.

x+y=133......(i)

x-y=49.......(ii)

solving eqn (i) and (ii) we get,

x+y=133

x-y=49

we solved it through elimination method.

Here, y and y cancelled out so, we've,

or, 2x=182

so, x=91

now putting value of x in any of the eqn.

in eqn(i)

or, x+y=133

or, 91+y=133

or, y=133-91

so, y=42

Therefore, the two numbers are 91 and 42.

Step-by-step explanation:

to find the volume all you need is length times width times height and you multiply it and that is your answer

Answer:

Ok, suppose that a man earns X, and a woman earns Y.

if X is larger than Y, then:

((X - Y)/Y)*100% is the percentage by which the man earns more than the woman. (where Y represents the 100%)

Replacing the given values, we can see that:

X = $1200

Y = $1000

(($1200 - $1000)/$1000)*100% = ($200/$1200)*100% = 0.20*100% = 20%.

If you want the expression only in decimals then you need to ignore the 100% in the equation, and you will have:

(X - Y)/Y

($1200 - $1000)/$1000 = 0.20

This would work for any given values of X and Y.

Other way to see this is:

If the man earns X and the woman Y, then we can see at the quotient:

X/Y

For the previous values we have:

$1200/$1000 = 1.2

This means that the man earns 1.2 times what the woman earns.

If we multiply that by 100%, we have:

1.2*100% = 120%

So the man earns the 120%, which is the 100% that earns the woman plus a 20%, that is what we found before.
