Answer: 38 minutes

Step-by-step explanation:

Answer: the value would be 3

Step-by-step explanation:

I did the worksheet for math!

Answer: s = 10

Step-by-step explanation:

3(s + 1) = 33

I 3 x s = 3s I 3 x 1 = 3 I

3s + 3 = 33

    -  3  - 3

__________

3s = 30

/3    /3

s = 10

Answer:

I think the answer is a because it not getting any smaller

Answer:

I think a trapezoid that is shorter than the pyramid because it's parallel to the base which automatically know it's not the same height because there's a certain length thats cut off.

Answer:

C. y </ 3/4x +10 and y<l -1/2x - 3

Step-by-step explanation:

Basically first do process of elimination with your focus on one equation

for example :: ( >l is greater then or equal to and <l is lease then or equal to)

focus -> y >l 3/4x + 10

1) determine which line has the y-intercept of positive 10

2) is the line dotted or straight? dotted line = > or < while straight line = >l or <l

this should get rid of B and D now

3) remember this = if the slope is - then the shaded portion would be the way that the less then sign is pointing

( y <l -4x then the shaded portion would be on the left side )

remember again = if the slope is + then the shaded portion would be the way that the greater then sign is pointing

( y <l 4x then the shaded portion would be on the right side )

so the line that we are focused on would have the right side shaded which means that it would be a <l ,so the answer would be C

hope this helped you understand how to solve these a bit better!

(tbh the day I figured how to solve these problems, I swear the whole world turned 180 degrees for me. )

Step-by-step explanation:

First I had to find 60% of 220.

220 × .60 = 132.

132 people are in favor so I have to subtract that number from 220 to find how many people were against.

220-132 = 88

88 people were against changing the mascot.

Answer:

5 servings

Step-by-step explanation:

Given that:

For a particular first snack  to be = 270 calories;

the servings = 3

Then, for the second snack, the calories = 450.

To estimate the servings for the second snack; we need to equate the first snack with the second snack.

Let y be the value of the unknown second snack

Then:

270 calories = 3 servings

450 calories = y servings

y servings = (450 calories × 3 servings) / 270 calories

y servings = 5 servings

Thus; the second snack needs to have 5 servings in order to be equivalent to the first snack

Answer

-15

Step-by-step explanation:

Answer:

Isolate the variable and simplify.

Step-by-step explanation:

13h = 109.2

h = 109.2 ÷ 13

h = 8.4

Your answer would be 8.4 units.

Don't forget units! :)

Answer:

3.225 gram

Step-by-step explanation:

Given that :

Initial weight = 0.06g

Rate of increase, r = 10% = 0.1 per day

Weight gain after 6 weeks

For an exponential model. f(x)

f(x) = a(1 + r)^x

Where ; a = initial amount ; r = growth rate ; x = period

Our model becomes :

f(x) : 0.06(1 + 0.1)^x

f(x) = 0.06(1.1)^x

Number of days in 6 weeks = 6*7 = 42 = x

f(42) : 0.06(1.1)^42

= 3.285 gram

Hence, weight gain after 6 weeks :

(3.285 - 0.06) g = 3.225 gram

Step-by-step explanation:

\(T T)/

Answer:

B. 13

Step-by-step explanation:

We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.

"The sum of two numbers is 46 and their difference is 20."

Meaning we have two equations :

X + Y = 46

X - Y = 20

Looking at the last part of "their difference is 20." We can assume X = Y + 20

So substitute the assumed equation into X + Y = 46

(Y + 20) + Y = 46

2y + 20 = 46

Subtract 20 from both sides :

2y = 26

Divide 2 by both sides :

y = 13

There you go.

Answer:

aₙ = 2*n*n - n -1

Step-by-step explanation:

a₁ = 0

a₂ = 5 = 2*2*2 -2-1 = 8-3 = 5

a₃ = 2*3*3 -3-1 = 18-4 =14

a₄ = 2*4*4 - 4-1 = 32-5 =27

......

aₙ = 2*n*n - n -1

Step-by-step explanation:

They are corresponding angles and therefore will be congruent :) Hope that helps!

Answer:the fourth number is =97

Step-by-step explanation:

Mean = total number of the given numbers( x1 +x2+ x3....) /  numbers given

Let the fourth number be x

given that the mean of 4 numbers = 88 and only 3 numbers are given

such that

Mean = total number of the given numbers( x1 +x2+ x3....) /  numbers given becomes

88=  (80 +90 + 85 + x ) / 4

88 x 4 =80 +90 + 85 + x

352=255+x

x= 352-255

x=97

Answer:

1.1 - 4.4c

Step-by-step explanation:

(-5.8c +1.4c​)+ (+4.2 - 3.1)

Answer:

45 degrees

Step-by-step explanation:

if <9 and <10 are corresponding, it means they are equal i.e <9 = <10

Since <9 and <10 are also complementary angles, their sum will be 90 degrees

<9+<10 = 90

<9 + <9 = 90

2m<9 = 90

m<2 = 90/2

m<2 = 45 degrees

Hence the measure of angle 9 is 45 degrees

Answer:

x = (s - 3πc^2) / 2πc.

Step-by-step explanation:

s = 2πcx + 3πc^2

2πcx  = s - 3πc^2

x = (s - 3πc^2) / 2πc.
