Answer:

1880 Milliliters(mL) = 3.97 pints

Step-by-step explanation:

This can be solved as a rule of three problem.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

Unit conversion problems, like this one, is an example of a direct relationship between measures.

Each ml has 0.002 pints. How many pints are there in 1880mL. So:

1ml - 0.002 pints

1880ml - x pints

x = 1800*0.002

x = 3.97 pints

1880 Milliliters(mL) = 3.97 pints

Question 16
Vadim26 [7]

Answer: 175

Step-by-step explanation: total = x + 5y dollars and dollars = 300 so

x + 5y = 300 then since we know y =  200 we can substitute that

x + 5(200) = 300 then subtract x from 200

x + 5(200 - x) = 300 now solve for x

x + 5(200) + 5(-x) = 300 we know 5 times 200 is 1000

x + 1000 - 5x = 300 then subtract 5x - x = -4x

-4x + 1000 = 300 switch around 1000 and 300

-4x = 300 - 1000 subtract 300 - 1000 = -700

-4x = -700 multiply

x = -700/(-4) then finish up and solve

x = 175

HELP ASAP plz, 45 pts
torisob [31]

Answer:

She didn't take the LCM, made an error while cross multiplying

x = -6

Step-by-step explanation:

a)she didn't take the LCM before cross multiplying.

Also, didn't cross multiply correctly

b) 1 -2/(x-2) = (x+1)/(x+2)

1 - 2/(x-2) = (x+2-1)/(x+2)

1 - 2/(x-2) = 1 - 1/(x+2)

1 - 2/(x-2) = 1 - 1/(x+2)

-2(x+2) = -1(x-2)

-2x-4 = -x+2

x = -6

What is the surface area of the rectangular pyramid
posledela

Answer:

<h2>41.74 m²</h2>

Step-by-step explanation:

We have:

rectangle 4.8 m × 3.8 m

two triangles with base b = 4.8 m and height h = 2.6 m

two triangle with base b = 3.8 m and height h = 2.9 m.

The formula of an area of a rectangle l × w:

A = lw

Substitute:

A_1 = (4.8)(3.8) = 18.24\ m^2

The formula of an area of a triangle:

A=\dfrac{bh}{2}

Substitute:

A_2=\dfrac{(4.8)(2.6)}{2}=6.24\ m^2\\\\A_3=\dfrac{(3.8)(2.9)}{2}=5.51\ m^2

The Surface Area:

S.A.=A_1+2A_2+2A_3\\\\S.A.=18.24+2(6.24)+2(5.51)=41.74\ m^2

Suppose P(E) = 0.3. Find P(not E). Suppose P(not E) = 65%. Find P(E).
larisa [96]
Try this option:
1. rule: P(E)+P(not E)=1.
2. according to the rule above
P(not E)=1-P(E)=1-0.3=0.7;
P(E)=1-P(not E)=(100-65)%=35%.

Evaluate: g(4):g(x) = 8x2 + 9x - 7
Elden [556K]

Answer:

g(4) = 157

Step-by-step explanation:

g(x) = 8x^2 + 9x - 7

Let x  =4

g(4) = 8 * 4^2 +9*4 -7

       =8*16 +36 - 7

        =128+36-7
