Answer:

y = 4.13

Step-by-step explanation:

Plux in x = 33 into y = 1/8x.

y = 1/8(33)

y = 4.125

Round to the nearest hundreth.

y = 4.13

one interior angle of a polygon is a right angle and each of the other interior angles is 126°. Calculate the number of sides of

Vikentia [17]

Answer:

There are 7 sides.

Step-by-step explanation:

Let's Use the formula that states that the sum of the angles of an n-sided polygon is given by.

S=(n−2)180

Since we are given that the two angles are right, the angles and each of the remaining angles is 144.

And Therefore, the sum is:

S=90

(n−2)144

(n−2)180

=90

+90

+(n−2)144

⇒(n−2)180

−(n−2)144

=180

⇒(n−2)(180

−144

)=180

⇒(n−2)(36

=180

⇒n−2=

180

⇒n−2=5

⇒n=5+2=7

Hence, the polygon has 7 sides.

Can someone help me with these three questions?

N76 [4]

Answer:

1. =

2. <

3. <

Step-by-step explanation:

Note: When comparing decimals you always place both decimals right above each other.

1 is equal to because once you put a 0 behind the 2.1 they are both the same.

2.10

2.1 <add 0 as space holder

2 is less than because they are both negative you are looking for which one is closest to zero.

-4.5 <add 0 as place holder

-4.25 <closest to zero

3 is less than because $\pi$ (pie) equals 3.141592654 which is less than 3.2.

3.141 <do not need to add whole decimal

3.2 <add two 0's as a placeholder

Will mark brainly<br> ASAP

Black_prince [1.1K]

The answer is 56 since complementary angles add up to 90 degrees and one of them is 34 degrees

Please help- I don't know math very well :(

Vanyuwa [196]

$\\ \sf\longmapsto f(x)=4(x-3)$

$\\ \sf\longmapsto f(3)$

$\\ \sf\longmapsto 4(3-3)$

$\\ \sf\longmapsto 4(0)$

$\\ \sf\longmapsto 0$

Here

a_n=7n

$\\ \sf\longmapsto a_{10}=7(10)=70$

d=1/4

a=1/4

$\\ \sf\longmapsto a_4=a+(n-1)d$

$\\ \sf\longmapsto a_4=\dfrac{1}{4}+(3)(\dfrac{1}{4})$

$\\ \sf\longmapsto a_4=1$

$\\ \sf\longmapsto y=2x-8$

$\\ \sf\longmapsto 2x=y+8$

$\\ \sf\longmapsto f(x)=\dfrac{8+y}{2}$

$\\ \sf\longmapsto a_n=n-1$

$\\ \sf\longmapsto 4.5- 4(0.5)$

$\\ \sf\longmapsto 4.5-2$

$\\ \sf\longmapsto 2.5$
