6/x= -2/18

Cross multiply. ( Multiply the numerators together ) . ( Multiply the denominators together (.

6*18= - 2*x

108= -2x

Divide by -2 for 108 and -2x

108/-2= -2x/2

x= -54

Answer: x= -54

A laboratory technician can clean 34 pipettes every hour with an automatic washer. How many can he clean in 12 minutes? (Hint: B

Semmy [17]

Answer:

Step-by-step explanation:

you can do a ratio where you have 34 over 60 then cross multiply that ratio with x over 12 and 60x=408 and it equals 6.8 but I am assuming you have to round up.

Find the greatest common factor of the following monomials: 20a3 and 8a2

dimulka [17.4K]

GCF of given monomials are $4a^2$

Solution:

Given that we have to find the greatest common factor

Given monomials are:

$20a^3 \text{ and } 8a^2$

When we find all the factors of two or more numbers, and some factors are the same, then the largest of those common factors is the Greatest Common Factor

Let us first find the GCF of 20 and 8 and then find GCF of variables and then multiply them together

GCF of 20 and 8:

The factors of 8 are: 1, 2, 4, 8

The factors of 20 are: 1, 2, 4, 5, 10, 20

Then the greatest common factor is 4

$GCF\ of\ a^3 \text{ and } a^2\\\\a^3 = a^2 \times a\\\\a^2 = a^2$

Thus GCF is $a^2$

Therefore GCF of monomials are:

$\text{GCF of } 20a^3 \text{ and } 8a^2 = 4 \times a^2 = 4a^2$

Thus GCF of given monomials are $4a^2$

The two hexagonal pyramids are similar.

spayn [35]

Answer: The approximate surface area of the larger pyramid is 159.31 ft².

Step-by-step explanation:

A pyramid is a solid,

And, When two solids are similar then the ratio of their surface area is the square of the scale factor of similarity.

Here, the scale factor of similarity

$=\frac{\text{Height of larger pyramid}}{\text{Height of smaller pyramid}}$

$=\frac{15}{6}$

Thus, by the above property,

$\frac{\text{ The surface area of larger pyramid}}{\text{The surface area of the smaller pyramid}}=(\frac{15}{6})^2$

It is given that, the smaller pyramid has a surface area of 25.49 ft²,

$\implies \frac{\text{ The surface area of larger pyramid}}{25.49}=\frac{225}{36}$

$\text{ The surface area of larger pyramid} = \frac{25.49\times 225}{36}$

$=\frac{5735.25}{36}$

$=159.3125\approx 159.31\text{ square ft}$

Help me please I’ll give a lot of points

Alenkasestr [34]

Answer:

21. B

22. D

23. C

24. y = 3x - 12

Step-by-step explanation:

21. it has to be a positive slope since the graph shows it is increasing/positive slope. Has to be A or B. But it isn't A because where x = 1 1/2, y doesn't equal 0 like the graph shows.

22. It is D if you rewrite the equation starting with y=, so you subtract 2x on both sides to get y = -2x +6. Parallel means slopes are the same, so the slope has to be -2, which is D.

23. The only one that fits the description is C.

24.

in standard form, rearrange the equation so only y is on one side, the rest on the other.

-4x + 2y = 2x - 24

first add 4x on both sides so -4x cancels out on the left hand side.

-4x + 4x + 2y = 2x + 4x - 24

simplify it and get 2y = 6x - 24

divide both side by 2

y = 3x - 12

plot this as shown with arrows on lines.

please give thanks :)
