Question

what does x = ?

please please help

5x(2x+20)= 90

10x=90-20

10x=70

x=70/10

x=7

plz give brainliest +thanks

Answer:

10°

Step-by-step explanation:

5x + 2x + 20° = 90° { Being complementary angles }

7x = 90° - 20°

7x = 70°

x = 70° / 7

x = 10°

Answer:

Step-by-step explanation:

Hello Dear!!!!

Here's your answer...

x=0.353535...

this is equation 1

multiply with 100

100x = 35.353535...

this is equation 2

equation 2 - equation 1

100x = 35.3535...

     x =    0.3535...

________________

99x = 35

x = 35/99

35/99 is the answer....

Answer:

Option B is correct.

Step-by-step explanation:

Recall that the domain is the set of (unique) inputs and the range is the set of outputs (which do not have to be unique).

The set of inputs of the given relation is {-1, 9, -10, 1}, and this set is also found in Option B.  The set out outputs is {7, 2, 6, -6|, which is in Option B.

Answer:

Dave and Anna:

1. Income highlight:

combined take home pay of $900/week

Total income: 4(900) - because 4 weeks in most months = $3600

-----------------------------

2. Expense highlights:

bi-weekly mortgage of $675

property taxes of $1800

Car expenses $160

Car insurance: $128

House insurance: $35

Saving for kids: $200

-------------

Expense calculations:

Mortgage bi-weekly = 675 x 2 = $1350/month

Property taxes = 1800/12 months/year = 150/month

everything else is already monthly

1350 + 150 + 160 + 128 + 35 + 200 = 2,023

---------------------------------------

income - expenses

$3600 - 2023 = $1,577 surplus

-----------------------------------------------------------------------------

Jacob:

Income highlights:

Canada Pension Plan $848/month

Old Age Security: $484/month

Total income: $1332

--------------------------

Expense highlights:

property tax: $3000/yr = $250/month

burial expenses: $100/month (for 6 more months)

golfing: $500/year = $41.67/month

bowling: $100/year = $8.33/month

Total expenses: 250 + 100 + 41.67 + 8.33 = 400

-----------------------------

Income - expenses:

1332 - 400 = $932 surplus

Answer:

$2772

Step-by-step explanation:

Given data

Principal= $8400

Rate= 5.5%

Time= 6 years

The expression for the simple interest on the loan is found using the expression below

SI= PRT/100

substitute

SI= 8400*5.5*6/100

SI= 277200/100

SI= $2772

Hence the simple interest is  $2772

Answer:The answer is actually 3,182.28

Step-by-step explanation:

An approximate equation for the line of best fit is y-hat = 0.018x - 24.5111.

A linear regression equation for the line of best fit would be y-hat = 0.018x - 24.5111 where

y-hat is the predicted value for the recorded weight gain (in pounds)

x is the additional daily caloric intake.

b) The pony's additional calorie intake increases, the weight gain also increases in pounds

c) Set x equal to 2300 and solve for y-hat:

y-hat = 0.018x - 24.5111

y-hat = 0.018(2300) - 24.5111

y-hat = 41.4 - 24.5111

y-hat = 16.8889

Therefore, the predicted value for the weight gain based on an additional 2300 calorie intake is 16.9 pounds.

Correct Question:

At a bake sale, plates of cookies, p, are sold for $5 each. The amount of money from the sale of cookies is expressed as dollars, d. Which equation represents the earnings of the bake sale?

1. p = 5d  

2. d = p + 5

3. d = 5p

Answer:

3. d = 5p

Step-by-step explanation:

As one plate of cookies price is 5 $

The d is expressed as numbers of dollars which are earned.

Earnings = d = 5 x number of plates sold (p)

therefore

d = 5p

Answer:

d+p5

Step-by-step explanation:

The question is incomplete, as the required lengths are not given.

I will use the following data set to answer the question.

[tex]Dataset: 35, 51, 39, 42, 68, 62, 32, 59[/tex]

First, is to determine the range of the dataset

[tex]Range = Highest - Least[/tex]

[tex]Range = 68 - 32[/tex]

[tex]Range = 36[/tex]

Next, we will make use of 4 classes. So, we divide range by 10 to get the number of class. 10 represents the interval

[tex]Class= Range/10[/tex]

[tex]Class = 36/10[/tex]

[tex]Class = 3.6[/tex]

[tex]Class \approx 4[/tex]

So, we use 4 classes

The vertex = 360° - 303° = 57

shaded angle = [tex]\frac{180-57}{2}[/tex] = [tex]\frac{123}{2}[/tex] = 61.5°

Answer:

Step-by-step explanation:

Since there are a total of 6 x 6 = 36 outcomes, then the probability that the sum will be greater than 10 is 3/36 = 1/12.

The probability that the resulting total is even or greater than 10 is 7/12.

Given that, two fair, six-sided dice are rolled.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes

Here, sample space of two dice is

S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6), (2,1),(2,2),(2,3),(2,4),(2,5),(2,6), (3,1),(3,2),(3,3),(3,4),(3,5),(3,6), (4,1),(4,2),(4,3),(4,4),(4,5),(4,6), (5,1),(5,2),(5,3),(5,4),(5,5),(5,6), (6,1),(6,2),(6,3),(6,4),(6,5),(6,6)}

Number of favorable outcomes = 18

Total number of outcomes = 36

Probability of getting the total is even = 18/36

= 1/2

Number of favorable outcomes = 3

Probability of getting the total is greater than 10 = 3/36

= 1/12

So, probability is 1/2 + 1/12

= 6/12 + 1/12

= 7/12

Therefore, the probability that the resulting total is even or greater than 10 is 7/12.

Answer:

Bunnies= 13    Chickens=28

Step-by-step explanation:

Let's put

x = bunnies------4 legs

y = chickens-----2 legs

x + y = 41----------------x= 41-y

4x+ 2y = 108

replace in 2nd equation

4(41 - y) + 2y = 108

164 - 4y + 2y = 108

2y = 56

y = 56/2= 28

x = 41 - 28= 13

3x+y=163 2x+3y=174

Answer:

The surface area of the sphere is = [tex]99426.41 yd^2[/tex]

Step-by-step explanation:

The area of a sphere can be calculated using this formula:

[tex]A=4\pi r^2[/tex]

However, we have a little problem: we do not have our radius yet to utilize in the formula above.

We can get our radius from the circumference of the circle which has been given to us.

circumference = [tex]2 \times \pi \times r[/tex]

[tex]r = \frac{circumference}{2 \pi} = \frac{558.92yd}{2\pi} = 88.95yd[/tex]

We now have our radius. we can input it into equation 1 above

The Surface area of sphere = [tex]4 \times \pi \times 88/95^2 = 99426.41yd^2[/tex]
