Use the expression -3/7+10

Mathematics

1 answer:

Aleks [24]3 years ago

Answer:

a. Jake told the negative value of the expression which cannot be equivalent to the original expression.

b. 10 - $\frac{\textbf{3}}{\textbf{7}}$ g

Step-by-step explanation:

a. The given expression is: $\frac{-3}{7}g + 10$

Multiplying through out by -, we get:

$- 10 + \frac{3}{7}g$ which was the expression given by Jake. Since, it is the negative of the original one, they cannot be equivalent.

b. $-\frac{3}{7}g + 10 = 10 - \frac{3}{7}g$

$= \frac{70 - 3g}{7}$

Hence, the answer.

(1) a) 5270 cl= ? dal

Ivanshal [37]

Answer:

Check below

Step-by-step explanation:

1) These metric volume units can be easily converted by dividing or multiplying by 10 and its multiple. Like this: each step up on the ladder multiply by 10. Each step down divide by 10

$a)5270 \:cl=527\:dl\\b)kl=5.3 \times 10=530 hl\\c)58000ml=5.8 dal =(\frac{58000}{10000})\\d)0.39 dal=3.9 l\\e)7.8 dal=780 dl\\f)57.2 ml=5.72 cl$ .

2) When it comes to area, the "ladder scheme" remains valid but now we'll multiply or divide by

$10^3$

Bear in mind these useful relations:

$1litre =\frac{1}{10^3}m^{3}$

$1 cm^{3} =1 ml$

$a) 3.7 l=3700 cm^{3}\\b)29.6 dm^{3}\\29.6 dm^{3} \rightarrow 29.6\times10^{3} cm^3=29.6\times10^{3} ml = 29.6\times10^{2} cl \:or\:2960 cl\\c)8.1l=8100 cm^{3}\\d)5l=\frac{5}{10^{-3}} m^{3}\\e)5.2 cl=52ml=52 cm^{3}=52\times10^{3}=52000 \:mm^{3}\\f)375 ml=375 cm^{3}\\g) 1300 cm^{3}=1300 ml=13 dl\\h) 8.6 ml= 8.6 cm^{3}\times\: 10^{3}=8600 mm^{3}\\i) 51.8\times 10^{11} l \rightarrow 51.8\times 10^{-11}km^{3}$

What value of y makes this equation true 14•y =126

Veseljchak [2.6K]

Answer:

y = 9

Step-by-step explanation:

to solve this equation, you first have to divide:

14 * y = 126

/14 /14

y = 9

and there is the answer. If you need to prove that y = 9, just input it into the equation.

14 * 9 = 126

126 = 126

Help please. I did my best to find the answer but...

lorasvet [3.4K]

Answer:

Step-by-step explanation:

This a special right triangle with angle measures of 30° 60° 90°

The side length that sees angle measure 30° is represented with a, the one that sees 90° is represented by 2a and the one that sees 60° is represented by a√2

AC sees angle B which has an angle measure of 60

(6√2)×(√2) = 24
