b) 0.069 + 0.84 can u guys plzz help me it math subject and the lesson name is decimal help ​

11.7

Formula: a^2 + b^2 = c^2

so substitute the numbers like this:

10^2 + 6^2 = c^2

both 10^2 and 6^2 are perfect squares:

10 × 10= 100 and 6 × 6= 36

100 + 36= c^2

add:

100 + 36 =

136 = c^2

now in order to get rid of the squared, you put it into a radical:

√136 = √c^2

note: whatever you do on one side, you do to the other

it's easier to use the calculator for this so put √136 and you're gonna get 11.66

since it's asking you to round it to the nearest tenth:

11.66 = 11.7

sorry if the explanation is kinda long ✋ i tried explaining it better in the end but i failed

Answer: I don't know how to do the first question but I think I did the 2nd question correctly I believe we learned this in 7th grade.  I am a freshman so if it is wrong I am sorry anyways the answers for #2 are

A: 34 for JK

B: 15 for MN

and C: 30 for JL

Perimeter: is 79.  

This was fun to do lol ik it wasn't much but better than nothing.  

Step-by-step explanation:

Answer:

we have:

k + 70° = 180°

=> k = 110°

u can see that i = 180°

=> k + i = 110° + 180° = 290°

Answer: y=8

Step-by-step explanation:

Answer:

r + ¾ = ⁷/₈

r = ⁷/₈ - ¾

⁷/₈ - ⁶₈ = ¹/₈

r = ¹/₈

Answer:

-2

Step-by-step explanation:

3*(-2)=-6

-6*(-2)=12

12*(-2)=-24

Answer:

log (2/5)

Step-by-step explanation:

The rule/law you have in mind is as follows:  log a - log b = log (a/b).

Thus, your log 2 - log 5 = log (2/5).

Answer:

Type A Type B

Median 52 grams 52 grams

Lower Quartile 49 grams 51 grams

Upper Quartile 57 grams 54 grams

Range 14 grams 8 grams

Interquartile Range 8 grams 3 grams

From this table we can see that both types of tomato have the same average mass because their medians are the same.

Comparing the medians and interquartile ranges shows that there is far more variation in the masses of the type A tomatoes, which means that the masses of type B are more consistent than those of type A.

However, comparing the two box and whisker plots, and the upper quartiles, shows that type A tomatoes will generally have a larger mass than those of type B.

Nevertheless, there will be some type A tomatoes that are lighter than any of type B.

Taking all this together, the gardener would be best advised to plant type A tomatoes in future as he is likely to get a better yield from them than from type B.

Answer:

45⁰

Step-by-step explanation:

use TanB=(3/3)

B=Tan-¹(3/3)

B=45⁰

Answer:

Step-by-step explanation:

Your answer

About all the sides are equal so we can say (10x + 44) side's triagle is twice than another triangle

So, 10x + 44 = 2( 8x - 23)

..... 10x +44 = 16x -46

...... X = 15

Answer:

[tex]2(x+2)/x+1[/tex]

Step-by-step explanation:

Answer:

2( x +2 )

x+1

Step-by-step explanation:

to add or subtract expressions expand them to make their denominators the same, multiply 1 time [tex]\frac{x-2}{x-2}[/tex]

since [tex]\frac{x}{x-2}[/tex] and [tex]\frac{x-2}{x-2}[/tex] have the same denominators add them by adding their numerators

combine x + x -2

factor [tex]x^{2}[/tex] - 4

to add or subtract expressions expand them and multiply by 1

have same denominator add them by adding their numerators

do the multiplications in 3 + ( x-2 )(x+2)

combine like terms in 3 + [tex]x^{2}[/tex] + 2x - 2x -4

divide [tex]\frac{2x-2}{x-2}[/tex] by [tex]\frac{-1 + x^{2} }{(x-2)(x+2) }[/tex] multiplying [tex]\frac{2x-2}{x-2}[/tex]

cancel out x-2 in both numerator and denominator

factor the expression that are not already factored

cancel out x-1  in both numerator and denominator

expand the expression

Answer:

Step-by-step explanation:

First Question: Equilateral triangles all have the same interior angles. 60 degrees. Size does not make the angles bigger. It makes the sides bigger.

Second Question: No the size does not influence the size of the interior angle.

Third Question: That's true for all polygons. Size is not affect the interior angle size.

Answer:

x = 7.4

Step-by-step explanation:

cos(42°) = x/10 or distance from bases / rope length

Using the calculator find the value of cos(42°):

cos(42°) = 0.74 = x/10

Find x using the value of cos(42°):

x/10 = 0.74

x = 7.4
