If a 100.8 kg cement bag had 20.35 kg removed from it, what is the new weight of the bag?
Snowcat [4.5K]
Just subtract 20.35 from 100.8
100.8 \: kg - 20.35 \: kg = 80.45 \: kg

if your bag weighs 100.8 kg and you scoop out 20.35 kg then weigh your bag it will be 80.45 bc u took out 20.35 kg of the cement to use. hope that explains it

State whether or not the following triangles are similar. If not, explain why not. If so, write a similarity statement
valentinak56 [21]

9514 1404 393

Answer:

  a) ∆RLG ~ ∆NCP; SF: 3/2 (smaller to larger)

  b) no; different angles

Step-by-step explanation:

a) The triangles will be similar if their angles are congruent. The scale factor will be the ratio of any side to its corresponding side.

The third angle in ∆RLG is 180° -79° -67° = 34°. So, the two angles 34° and 67° in ∆RLG match the corresponding angles in ∆NCP. The triangles are similar by the AA postulate.

Working clockwise around each figure, the sequence of angles from lower left is 34°, 79°, 67°. So, we can write the similarity statement by naming the vertices in the same order: ∆RLG ~ ∆NCP.

The scale factor relating the second triangle to the first is ...

  NC/RL = 45/30 = 3/2

__

b) In order for the angles of one triangle to be congruent to the angles of the other triangle, at least one member of a list of two of the angles must match for the two triangles. Neither of the numbers 57°, 85° match either of the numbers 38°, 54°, so we know the two triangles have different angle measures. They cannot be similar.

Which expression is equivalent to the following complex fraction?
user100 [1]

The equivalent expression of (1 + \frac{1}{y}) \div (1-\frac 1y) is \frac{y + 1}{y-1}

<h3>How to determine the equivalent fraction?</h3>

The fraction is given as:

(1 + \frac{1}{y}) \div (1-\frac 1y)

Take the LCM

\frac{y + 1}{y} \div \frac{y-1}y

Express as products

\frac{y + 1}{y} \times \frac{y}{y-1}

Evaluate the product

\frac{y + 1}{y-1}

Hence, the equivalent expression of (1 + \frac{1}{y}) \div (1-\frac 1y) is \frac{y + 1}{y-1}

Hence, second option is the true option.                            {Result of spin, card color}

{Green, Purple} {Yellow, Purple}  {Purple, Purple }

{Green, Green}  {Yellow, Green}  {Purple, Green}

Step-by-step explanation:

It is given that:

A spinner with 3 equal sectors is shown in the figure. The colors Green, Yellow, and Purple are marked on it.

Two cards are shown on the right side. Their colors are Purple and Green.

The table that identifies the sample space of spinning the spinner and then selecting  a card is:

     {Result of spin, card color}

{Green, Purple} {Yellow, Purple}  {Purple, Purple }

{Green, Green}  {Yellow, Green}  {Purple, Green}

( Since in rest of the options the red color in the sample space but there is no card or no such color in the spin which is red)
