Answer:

9

Step-by-step explanation:

Step-by-step explanation:

you just do 180 - 90 = 90 degree is x value

Answer:

x should equal 90.

Step-by-step explanation:

x is the sum of those two interior angles. 50 + 40 equals 90.

Answer:

88

Step-by-step explanation:

14 dollars is her allowance

Answer:

20 grams will be left.

Step-by-step explanation:

Half-life is 11 days

This means that in each 11 days, you lose 50% of the amount.

33 days

33/11 = 3 half-lifes.

You start with 160 grams

After 11 days: 160/2 = 80 grams

After 22 days: 80/2 = 40 grams

After 33 days: 40/2 = 20 grams.

20 grams will be left.

Answer:10

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\for\ a \ sample(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\where\ x=raw\ score,\mu=mean, \sigma=standard deviation[/tex]

Given that n = 49, μ = 260 mg/dL, σ = 35 mg/dL

a) For x < 210:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{210-260}{35/\sqrt{49} } =-10[/tex]

From the normal distribution table, P(x < 210) = P(z < -10) = 0.0001

b) For x > 205:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{205-260}{35/\sqrt{49} } =-11[/tex]

For x < 215:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{215-260}{35/\sqrt{49} } =-9[/tex]

P(205 < x < 215) = P(-11 < z < -9) = P(z < -9) - P(z < -11) = 0.0001 - 0.00001 = 0.00009

c) For x < 200:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{200-260}{35/\sqrt{49} } =-12[/tex]

From the normal distribution table, P(x < 200) = P(z < -12) = 0.00001

d) For x > 222:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{222-260}{35/\sqrt{49} } =-7.6[/tex]

From the normal distribution table, P(x > 200) = 1 - P(z < -12) = 1 - 0.0001 = 0.9999

Answer:

80

Step-by-step explanation:

The sum of the opposite inscribed angles is 180

x+100 = 180

X = 80

Answer:

2080 meters

Step-by-step explanation:

An hour is double of 30 minutes so, if you double the length it went you would get how far it goes in an hour, 2080 meters.

Step-by-step explanation:

Answer:

a. 42

b. 122

a. 57

b. 130

Step-by-step explanation:

For problem A:

because both of these values have positive numbers, just use normal subtraction

82 - 40 = 42 degrees warmer

For problem B:

because we are subtracting a negative number from a positive number, we add both of these numbers because 82 - -40 can also be equal to 82 + 40

82 - -40 = 122

For problem A:

the sentences 30m up a cliff and 87m up a cliff are describing positive values.

87 - 30 = 57

For problem B:

Now in this problem, the sentence 100m above the surface is describing a positive value, but the sentence 30m below the surface describes a negative value

how do I know this?

if the sentences above the surface and below the surface are describing positive and negative values, then there has to be a neutral value ( which is 0)

0 meters = the surface, because they are using both positive and negative values, meaning that the surface is the neutral value

by using a number line, you can draw it out like this

below the surface-------------------------the surface----------------------------above the surface

-30--------------------------------------------0--------------------------------------------100

therefore, 100 - - 30 = 100 + 30 = 130

Answer:

6,7,7 is your answer

6.

3x+2=2x+8

x=6

Step-by-step explanation:

7.14x+12+10x=180

24x=180-12

x=168/24=7

8.9x-3=7x+11

9x-7x=11+3

2x=14

x=14/2=7

Answer:

x(the number)=3

Step-by-step explanation:

3×3+3squared = 18

Answer:

3x + x^2 = 18

x^2 + 3x - 18 = 0

(x + 6)(x - 3) = 0

x + 6 = 0

x = -6

x - 3 = 0

x = 3
