Help very confusing to me???!

mart [117]

Answer:

Heyy mate... here's ur ans ;)

they asked us to apply pythagarus theorem becoz that theorem proves

that it is rectangle so lets get started

( p - perpendicular / b - base / h - hypotenuse )

a) =>

B = 8.1 m

P = 6.3 m

H = 10.15m

Now applying thm => H^2=p^2+b^2

(8.1)^2 + (6.3)^2 = (10.15)^2

65.61 + 39.69 = 103.02

so now LHS = 105.3 and RHS = 103.02 hence

LHS not equal to RHS

so is not rectangle

b) =>

B = 14.4

P = 5.2

H = 15.31

Now applying thm => H^2=p^2+b^2

(5.2)^2 + (14.4)^2 = (15.31)^2

27.04 + 207.36 = 234.39

LHS = 234.4 and RHS = 234.39

just taking approximation rhs is 234.4

hence

LHS = RHS

so it is a rectangle

What is the measure of angle x? Enter your answer in the box.<br> x=

GREYUIT [131]

Answer:

x = 48°

Step-by-step explanation:

42 + 90 + x = 180 (we can tell because it is a straight line and straight lines are supplementary, ie = 180)

Rearrange the equation so that x is on one side:

x = 180 - 90 - 42

Simplify

x = 48°

Match each term with its notation.

Ugo [173]

Answer:

_<u>k_</u> The number of treatment conditions

<u>_n_</u> The number of scores in each treatment.

<u>_N_ </u>The total number of scores in the entire study.

<u>_T</u>_ The sum of the scores for each treatment condition.

<u>_G</u>_ The sum of all of the scores in the research study.

<u>_F</u>_ The F-ratio

Step-by-step explanation:

These notations are ANOVA (Analysis of variance) notations, where

k is the number of treatment conditions

n is the number of scores in the treatment

N is the total number of scores in the entire study

T is the sum of scores for a specific treatment

G is the sum of all scores in the study

and F is the F-ratio.

Now, for the question, we will match each term with its notation

_<u>k_</u> The number of treatment conditions

<u>_n_</u> The number of scores in each treatment.

<u>_N_ </u>The total number of scores in the entire study.

<u>_T</u>_ The sum of the scores for each treatment condition.

<u>_G</u>_ The sum of all of the scores in the research study.

<u>_F</u>_ The F-ratio

a restaurant sells a coffee refill mug for $6.75. Each refill costs $1.25. Last month keith spent $31.75 on a mug and refills wr

evablogger [386]

y= 1.25x+6.75
Make 31.75 y because that is the total cost he paid.
1.25x+6.75=31.75
1.25x=25
x=20
So he had 20 refills.
