So the ones that would be true are m<MKQ+m<PKQ=m<PKM and PK is a bisector. These two are the only ones, the first one wouldn't be true, because we don't know if PKQ and QKM are congruent or not so we can't prove if it's a bisector or not. The second one wouldn't be true for the same reason, we aren't given any information about those two angles. The third isn't true because again, we don't know the angle measures or if they are congruent or not. The fourth is true because the segments of an angle add up to the whole angle. The next one is true because we are given the information that <PKM is a right angle and therefore 90° and a straight angle, which <JKM is said to be is 180°. the last one is not true because we don't know the measures of either of the angles and are given nothing about any congruent angles.

Solve: (-5/6) × (9/20) + (-5/6) × 7/25 = ?

jonny [76]

$\bf \underline{★ How \:to\: do -} \\$

Here, we are given with four fractions to multiply two of them and to add two of them. If we add them directly by taking the LCM and adding them is not a similar way. We can clearly observe that in those four fractions, we have two fractions as common i.e, we have two fractions as same. If we have two fractions or numbers as same, we can solve the sum by an other concept called as distributive property. In this property, we multiply the common fraction with the sum of other two fractions. This concept can also be done with fractions as well as integers. So, let's solve!!

$\:$

$\bf \underline{➤ Solution-} \\$

${\tt \leadsto \dfrac{(-5)}{6} \times \dfrac{9}{20} + \dfrac{(-5)}{6} + \dfrac{7}{25}}$

Group the non-common fractions in bracket.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{9}{20} + \dfrac{7}{25} \bigg)}$

First we should solve the numbers in bracket.

LCM of 20 and 25 is 100.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{9 \times 5}{20 \times 5} + \dfrac{7 \times 4}{25 \times 4} \bigg)}$

Multiply the numerators and denominators in the bracket.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{45}{100} + \dfrac{28}{100} \bigg)}$

Now, write both numerators in bracket with a common denominator.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{45 + 28}{100} \bigg)}$

Now, add the numerators in bracket.

${\tt \leadsto \dfrac{(-5)}{6} \times \bigg( \dfrac{73}{100} \bigg)}$

Write the numerator and denominator in lowest form by cancellation method.

${\tt \leadsto \dfrac{\cancel{(-5)} \times 73}{6 \times \cancel{100}} = \dfrac{(-1) \times 73}{6 \times 20}}$

Now, multiply the numerators and denominators.

${\tt \leadsto \dfrac{(-73)}{120}}$

$\:$

${\red{\underline{\boxed{\bf So, \: the \: answer \: obtained \: is \: \: \dfrac{(-73)}{120}}}}}$

A 40 oz jar of peanut butter costs $5.75 , what is it’s unit rate? (round to the nearest cent)

expeople1 [14]

Answer:

$0.14 per oz

Step-by-step explanation:

Step 1: Divide $5.75 by 40.

$5.75/40$
$0.14375$

Step 2: Round to the nearest hundredth.

0.14375 ≈ 0.14
0.14

Therefore, the answer is $0.14 per oz.

Kruka [31]

Answer:

24 slices

Step-by-step explanation

Add the lengths of the two cucumbers together to get 8 inches total. Now if the ratio is 3/8 all you have to do is multiply 8 by 3 to get the number of slices.
