Tom, Lisa, and Jane are competing in a cooking competition. They all used different amounts of sugar from a can containing 4 pou

avanturin [10]

Convert all to decimals
percent means parts out of 100
13%=13/100=0.13

'of' means mutiply

Tom=13% of 4
tom=0.13 times 4
tom=0.52 lb

Lisa=0.6 lb

Jane=0.12 of 4
jane=0.12 times 2
jane=0.48

Tom=0.52
Lisa=0.60
Jane=0.48

Rectangle EFGH is similar to rectangle JKLM. Which proportion can be used to

Dominik [7]

*See attached picture for the diagrams being referred to

Answer:

C. ⁵/12= ²/x

Step-by-step Explanation:

Given that rectangle EFGH is similar to rectangle JKLM, it means the corresponding sides of both rectangles are similar, and as such the ratios if the corresponding sides of rectangle EFGH and rectangle JKLM would be equal.

Thus, EF/JK = FG/KL

Since, EF = 5; JK = 12; FG = 2; and KL= x, therefore, the proportion to use in finding x would be:

⁵/12= ²/x

WARNING : NON SENSE ANSWER REPORT TO MODERATOR

Rzqust [24]

Answer:

$\frac{180}{147}$

Step-by-step explanation:

Simplify $(\frac{3}{-7} - \frac{11}{21} )$

$=> \frac{(-3 \times 3) - 11}{21}$

$=> \frac{-9 - 11}{21}$

$=> \frac{-20}{21}$

Find the additive inverse of $\frac{-20}{21}$ by using its property - <em>"Sum of a number & its additive inverse is always zero". </em>Assume that 'x' is an additive inverse of $\frac{-20}{21}$ .
