A) ratio is 250:1000 = 1:4

B) for 250 mL it is 1 liter now for 2000mL it is X .

=> x = 2000/250 = 8 liters

C) volume of water in 6L of made up juice is 1500 mL

D) 1 liter - 5 glasses

In the diagram, the measure of angle 3 is (23x)°, and the measure of angle 4 is (7x)°.

Sophie [7]

Angles three and four are a linear pair, meaning that they they form a line. When two angles make a line, the measures add up to 180°. Adding the two values together, we see that 3x+27x=180. Simplifying and solving for x, we get 30x=180 ⇒ x=6.

The question, however, is asking for the measure of angle 4. Thus, we plug x=6 into 7x to get 6(7)=42.

1 7/10 x 2/3 what is the product

Ludmilka [50]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{1 \frac{2}{15}}}}}}$

Step-by-step explanation:

$\sf{1 \frac{7}{10} \times \frac{2}{3} }$

Convert the mixed number into improper fraction

$\longrightarrow{ \sf{ \frac{10 \times 1 + 7}{10} \times \frac{2}{3}}}$

$\longrightarrow{ \sf{ \frac{17}{10} \times \frac{2}{3}}}$

To multiply one fraction by another, multiply the numerators for the numerator, and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term

$\longrightarrow{ \sf{ \frac{17 \times 2}{10 \times 3}}}$

$\longrightarrow{ \sf{ \frac{34}{30}}}$

$\longrightarrow{ \sf{ \frac{17}{15} }}$

Convert the improper fraction into mixed number

$\longrightarrow{ \sf{1 \frac{2}{15} }}$

Hope I helped!

Best regards! :D

Sarah has a laundry bag in the shape of a cylinder. The area of the bottom of the bag can be written as the function A(x) = x2 -

NNADVOKAT [17]

As we know the volume of a prism is the product of height and base are

H(x)= height, A(x)= Base area

Thus,
When volume = height(base area )

V(x)= A(x) · H(x)
= (x²-2)(5)
= 5(x² -2)
