The value of x such that the hcf is 26 and the l.c.m is 1092 is 156

The numbers are given as:

182 and x

The HCF and LCM are given as:

HCF = 26

LCM = 1092

As a general rule;

The product of LCM and HCF of x and y equals the product of x and y

So, we have:

182 * x = 26 * 1092

Divide both sides by 182

x = 156

Hence, the value of x is 156

The maximum number of African cichlids which can put by Chiletso  in this cylindrical fish tank is 19.

Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.

The volume of the cylinder can be given as,

V=(πd^2h)4

Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.

The height of tank is 30 inches and the length of the diameter of the base is 27.5 inches. Thus, the volume of it is,

V=[π(27.5)²(30)] /4

V=17818.72 cubic inches.

One us gallon is equal to approximately 231 cubic inches. Thus, the volume in gallon is,

V=17818.72/231

V=77.12 gallons.

A good rule of thumb is to have about 3 inches of fish per 2 gallons of water. The number of 6 inches cichlids the can put in 77.12 gallons tank is,

V=(77.12 x 3)/(6 x 2)

V=19.28

Thus, the maximum number of African cichlids which can put by Chiletso  in this cylindrical fish tank is 19.

Answer:

D. It takes them more time to deliver packages because 157.3 x 1.25 = 196.625

Step-by-step explanation:

In the question, it states that this week it took the delivery drivers 1.25 times longer to deliver packages than last week, meaning that it took more time to deliver the packages this week than last week. With this, we can eliminate choices A and C.

Because it took them 1.25 times longer, then we can multiply 157.3 by 1.25 to find the correct sum.

157.3 × 1.25 = 196.625

The only answer choice that matches this information completely is choice D, so that is the answer.

Answer:

It's b, 54, because that makes the sum.

Using the normal distribution, it is found that the tree must have heights between 9.49 cm and 10.51 cm.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given, respectively, by:

[tex]\mu = 10, \sigma = 2[/tex]

Considering the symmetry of the normal distribution, the middle 20% is between the 40th percentile(Z = -0.253) and the 60th percentile(Z = 0.253), hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.253 = \frac{X - 10}{2}[/tex]

X - 10 = -0.253 x 2

X = 9.49.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.253 = \frac{X - 10}{2}[/tex]

X - 10 = 0.253 x 2

X = 10.51.

Answer:

Answer = 5.5

Step-by-step explanation:

The formula for finding the surface area of a cube is SA = 6(s^2) where s = sides. Since we know the surface area we plug it in for SA. So,

181.5 = 6*s^2

Now we divide 6 by both sides to get

30.25 = s^2

Now we have to find the square root of both sides to get

5.5 = s

Step-by-step explanation:

The sum of 1/2 and y is equal to 3/4.

The equation to represent this is:

Answer:

(-2,15) (3,0)

Step-by-step explanation:

By substituting the x value in the coordinate (the first number in the bracket) and solving the equation, you must get the y value in the coordinate (second number in the bracket.

So that is to say:

A

y= -3x + 9

y = -3(-2) + 9

y = 6 + 9

y= 15

Also note that B is not one of them, because the y value you get when you substitute the x value in the equation is NOT NEGATIVE 6.

Answer:

D.  The graph of g is the graph of f shifted 2 units down.

Step-by-step explanation:

Transformations

f(x) - a :  vertical shift of "a" units down

f(x) + a : vertical shift of "a" units up

f(x - a)  : horizontal shift of "a" units to the right

f(x + a) : horizontal shift of "a" units to the left

If  g(x) = f(x) - 2

Then g(x) is f(x) shifted 2 units down.

Answer:

302 1/10 is our fraction form more known to be a mixed number.

Step-by-step explanation:

Fraction form from decimal is to keep our 302 and make .1 a fraction.

This is because we already have a base/whole number and just need a fraction to make this decimal an improper fraction. 0.1 is equivalent to 1/10 because in order to get to 0.1 you need to move the decimal point 1 digit to the right. You could also do 1 divided by 10.

302 1/10 is our fraction form more known to be a mixed number.

5=18

Step-by-step explanation:

they are counting by 2s      10,12,14,16,18

Hope this helps!

Answer:

18

Step-by-step explanation:

It seems like for this pattern, as the x-value(base value) increases, the corresponding y-value(value changing with the base value) increases by 2 given that the function starts with a y-intercept of 8. So at the value 0, the corresponding number would be 8. So in this case, by creating a function regrading this information we can solve for the corresoponding value of 5: y = 2x + 8

y = 2 * 5 + 8

y = 10 + 8

y = 18

5 = 18

Another way to approach this is just by following the pattern given to us in the description. We see that the pattern starts at 10, and increases by 2 for each increasing base value. Therefore, if 4 = 16, then 16 + 2 = 5, so 5 = 18.

1500 mg is the least mass

Step-by-step explanation:

Lets convert them all to the same mass unit,

1500 mg to grams: 1500 mg / 1000 = 1.5 grams

13.2 kg to grams: 13.2 kg x 1000 = 13,200 grams

30000 cg to grams: 30,000 cg / 100 = 300 grams

7428g no conversion needed!

1.5 grams, 13,200 grams, 300 grams, 7,428 grams
