Answer:

2×10^10

Step-by-step explanation:

Answer:

1. You should mix 5 cups of yellow paint with 1 cup of blue paint. The table shows that the ratio is 1:5 (blue:yellow) so 1 cup of blue paint means you need 5 cups of yellow paint.

2. Using the same ratio (1:5), you can multiply both numbers by any number and get the same shade of green.

5 cups of blue paint will need 25 cups of yellow paint.

(1 x 5 = 5  :   5 x 5 = 25)

Answer:

∠LMP = 77

∠NMP = 103

Step-by-step explanation:

to find the measure of ∠LMP and ∠NMP

we know that ∠LMN is a straight line so that will be 180 degrees

so you can say that

∠LMP + ∠NMP = 180

(-16x +13) + (-20x +23)  = 180

-16x +13 -20x + 23  = 180

-36x + 36 = 180

-36x = 180-36

-36x = 144

x = 144/-36

x = -4

∠LMP = (-16x +13)

          = ( -16 (-4) + 13)

         = ( 64 + 13)

         = 77

∠LMP = 77

∠NMP = (-20x +23)

          =  (-20 (-4) + 23)

          = 80 + 23

          = 103

∠NMP = 103

Answer:

80°

Step-by-step explanation:

8x = 7x + 10

They are alternate(different sides of the intersecting or transversal line) interior(inside the two parallel lines)angles

alternate interior angles

8x = 7x + 10

x = 10

7(10) + 10 = 80

Answer:

n is 2.4

Step-by-step explanation:

[tex]3(n - 4) + 2(4n - 5) = (n + 2)[/tex]

open the brackets:

[tex](3n - 12) + (8n - 10) = (n + 2)[/tex]

collect like terms together:

[tex]3n + 8n - n = 2 + 12 + 10 [/tex]

factorise out n :

[tex]n(3 + 8 - 1) = 24 \\ 10n = 24 [/tex]

divide all sides by 10 :

[tex] \frac{10n}{10} = \frac{24}{10} \\ \\ n = 2.4[/tex]

===============================================================

Explanation:

First, let's calculate angle BYC. This is the angle formed by the chords that subtend the arcs mentioned. This angle faces or is aimed toward the direction of the arcs. To find this angle, we'll average the arc measures like so:

angle BYC = (arcAD + arcBC)/2

angle BYC = (50+120)/2

angle BYC = 170/2

angle BYC = 85 degrees

Then we'll use the idea that angles BYC and DYC are supplementary (aka they form a straight 180 degree angle)

angleBYC + angleDYC = 180

angleDYC = 180 - angleBYC

angleDYC = 180 - 85

angleDYC = 95 degrees

which is why the answer is choice D.

Unit conversion involves the conversion of a metric unit to another unit of the same quantity.

[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]

Let:

[tex]x = 19.3 pm/ks^2[/tex]

Multiply by [tex]10^{-17[/tex] to convert megameter per squared kiloseconds

[tex]x = 19.3 \times 10^{-17} Mn/ks^2[/tex]

Divide by [tex]10^{24[/tex] to convert to megameter per squared nanoseconds

[tex]x = \frac{19.3 \times 10^{-17}}{10^{24}} Mn/ns^2[/tex]

Apply law of indices:

[tex]x = 19.3 \times 10^{-17-24} Mn/ns^2[/tex]

[tex]x = 19.3 \times 10^{-41} Mn/ns^2[/tex]

Hence:

[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]

Answer:

2x

Step-by-step explanation:

f(x) = x -4

Step 1:

y = x - 4

Step 2: Replace y with x

x = y - 4

Step 3: Find y

x + 4 = y  

f(-x) = x + 4

f(x) + f(-x) = (x - 4)+ (x + 4) = 2x
