Answer: QPS=SPK by reason ASA

Step-by-step explanation:

So first we identify the given parts which already says it. We know PQ=PR right so we consider that a side. Then angle QPR= angle PRK. So we consider that a angle. And angle Q= angle PRK. Then we can figure out the rule. The rule is ASA because side PQ is inside of angle QPR and Q.

Mr. Snow bought 90 grams of Christmas candy for each of his 14 grandchildren. How many total kilograms of candy did he buy?

nignag [31]

Answer:

1.26 kg.

Step-by-step explanation:

We have been given that Mr. Snow bought 90 grams of Christmas candy for each of his 14 grandchildren. We are asked to find the amount of candy bought by Mr. Snow in kilograms.

First of all, we will find the amount of candy in grams by multiplying 90 grams by 14 as:

$\text{Amount of candy bought in grams}=14\times 90$

$\text{Amount of candy bought in grams}=1260$

We know that 1 kilogram is equal to 1000 grams. To convert 1260 grams into kg, we will divide 1260 by 1000 as:

$\text{Amount of candy bought in kilograms}=\frac{1260}{1000}$

$\text{Amount of candy bought in kilograms}=1.26$

Therefore, Mr. Snow bought 1.26 kilograms of candy.

2.8, 3.4, 4.0, 4.6, . . . Write an equation for the nth term of the arithmetic sequence. Then find a50.

vova2212 [387]

Answer:

a_n = 2.2 + 0.6 n

a_50 = 32.2

Step-by-step explanation:

What's the common difference of this series?

$a_1 = 2.8$

$a_2 = 3.4$

Common difference = $a_2 - a_1 = 3.4 - 2.8 = 0.6$ .

Expression for the nth term:

$a_n = a_1 + (n - 1) \cdot\text{Common Difference} \\\phantom{a_n } = 2.8 + 0.6 \; (n-1) \\\phantom{a_n} = 2.8 + 0.6 \; n - 0.6\\\phantom{a_n} = 2.2 + 0.6\; n$

n = 50 for the fiftieth term. Therefore

$a_{50} = 2.2 + 0.6 \times 50 = 32.2$ .

Which choice gives a valid first step to solve 2(w − 3) = 5? Exclude any choice where the explanation for the step is false.

UNO [17]

Answer:

D. Use the Distributive Property. You clear the parentheses and then solve the two-step equation.

Step-by-step explanation:

Given problem;

2(w − 3) = 5

To solve this problem:

Use the distributive property to clear the parentheses;

2w - 6 = 5

Then, collect like terms, add 6 to both sides;

2w = 5 + 6

2w = 11

Now divide both terms by 2

w = $\frac{11}{2}$

An entrepreneur estimates that the total profit (profit = total revenue minus total cost) from his proposed company will be give

SOVA2 [1]

No profit means P(x)=0: x³-4x²+3x-12=0
factor by regrouping: x²(x-4)+3(x-4)=0
take out (x-4): (x-4)(x²+3)=0
x=4 or x²=-3
x² is not a negative number, so x=4 is the only answer.

lilavasa [31]

Answer:

The teacher should use the median for Amo and the mean for Javier.

Complete question;

Mr. Malloy wants to make sure Amo and Javier get the best possible grade after five tests and can either give a grade based on the median or the mean

Test

Number

Amo’s Scores

Javier’s Scores

What measure of center should Mr. Malloy use for Amo and for Javier for the best possible grade?

The teacher should use the mean for both Amo and Javier.

The teacher should use the median for both Amo and Javier.

The teacher should use the median for Amo and the mean for Javier.

The teacher should use the mean for Amo and the median for Javier.

Attached is the image of their scores

Step-by-step explanation:

Amo's Score in Ascending Order: 55,89,90,92,97

Javier's Score in Ascending Order: 65,65,68,92,97

For Amo;

Mean = (55+89+90+92+97)/5 = 84.6

Median = 90

For Javier;

Mean = (65+65+68+92+97)/5 = 77.4

Median = 68

Therefore,

Median is higher for Amo and mean is higher for Javier

So, The teacher should use the median for Amo and the mean for Javier.
