An artist is making a mosaic using glass
tiles. He uses a total of 600 tiles.
The ratio of red tiles to blue tiles is 1:2.
How many red tiles does he use?

Answer: C. X + 44

Step-by-step explanation:

Let x be the unknown number.

Given statement : "44 more than an unknown number".

By using addition operation ,

Mathematical expression for "44 more than an unknown number" = 44 +x

Hence, the correct expression is x+44.

So, the correct option is C.

Answer:

seats are in row 12 is 136

seats are in row 136 is 880

seats are in the auditorium is 1071000

Step-by-step explanation:

given data

rows of seat = 51

first row seats =  70

each row seats = 6

to find out

How many seats are in row 12 ,136 and How many seats are in the auditorium

solution

it is AP as 70 , 76 , 82, 88 ............

here A = 70 , d = 6

for n = 12 and 136

so An = a + (n-1)d       .........1

A(12) = 70 + (12-1)6

A(12) = 136

and

A(136) = 70 + (136-1)6

A(136) = 880

and

for total seat we get here Sn for 51 row

Sn = [tex]\frac{n}{2}[/tex] × [ 2a(n-1)d]     ...........2

put here value

Sn = [tex]\frac{51}{2}[/tex] × [ 2(70)(51-1)6]  

Sn = 1071000

Answer:

The 90% confidence interval for pis (0.7342, 0.8658).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

For this problem, we have that:

100 rats mothers, 80 went right. So [tex]n = 100, \pi = \frac{80}{100} = 0.8[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8 - 1.645\sqrt{\frac{0.8*0.2}{100}} = 0.7342[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8 + 1.645\sqrt{\frac{0.8*0.2}{100}} = 0.8658[/tex]

The 90% confidence interval for pis (0.7342, 0.8658).

Answer:

[tex]b=\sqrt{7}[/tex]

Step-by-step explanation:

When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know a and c we can plug that in to find out what b could be but we won't actually solve it.

[tex]a^2+b^2=c^2\\3^2+b^2=4^2\\9+b^2=16\\b^2=7\\\sqrt{b^2}=\sqrt{7}\\b=\sqrt{7}[/tex]

So b would equal whatever the square root of 7 is.

Answer:

37 m

Step-by-step explanation:

First, use trigonometric ratio to find the distance between the top of the shorter silo to the top of the taller silo.

Let the distance between the top of the smaller silo and the top of the taller silo be x.

Thus, we would have:

Tan 30 = opp/adj = x/25

Tan 30 = x/25

Multiply both sides by 25

25*Tan 30 = x

x = 14 m (nearest meter)

The height of the taller silo = height of the smaller silo + x

= 23 m + 14 m

= 37 m

Answer:

i think its 32 pints

Step-by-step explanation:

im pretty sure but sorry if im wrong ❤️

The remaining honey in the beehive is 4 gallons and 2 quarts, or 4 quarts and 2 ounces.

we need to convert the given measurements to quarts and ounces and then subtract them from the original 5 gallons.

1 gallon is equal to 4 quarts, and 1 quart is equal to 32 ounces.

4 gallons can be converted to quarts by multiplying by 4:

4 gallons × 4 quarts/gallon = 16 quarts

1 pint is equal to 2 cups, and 1 cup is equal to 8 fluid ounces.

1 pint and 2 ounces can be converted to ounces:

1 pint × 2 cups/pint × 8 ounces/cup = 16 ounces

2 ounces (already in ounces) = 2 ounces

Now, let's add up the converted measurements:

16 quarts + 16 ounces + 2 ounces = 16 quarts and 18 ounces

To find the remaining honey, we subtract the converted measurements from the original 5 gallons:

5 gallons - 16 quarts - 18 ounces = 4 gallons and 2 quarts

Answer:

  15.8 ÷ 3.9

Step-by-step explanation:

To make up this problem, we can start with two numbers whose quotient we know is 4, such as 16 and 4. Then we can choose two numbers that round to these values, such as 15.8 and 3.9

__

The problem 15.8 ÷ 3.9 has an estimated quotient of 4. The estimate is found by rounding each value to the nearest integer and finding the quotient of those numbers: 16/4 = 4.

Additional comment

The actual quotient is 4 2/39, about 4.05128.

Answer:

2.5v + 5 < 5v is the correct answer.

Step-by-step explanation:

Given that:

Cost to rent one game at store S = $2.50

Monthly fee = $5.00

Let,

v be the number of video games.

Total cost = 2.50v + 5

Cost to rent one game at store T = $5.00

y = 5v

Now,

Store S < Store T

2.50v + 5 < 5v

Hence,

2.5v + 5 < 5v is the correct answer.

Answer and Step-by-step explanation:

First off, write the equation in slope intercept form.

y = [tex]-\frac{2}{3} x + 2[/tex]

(3, 0) is the x intercept, so when we go up 2 and left 3 (opposite of the slope, since we want to find the y-intercept), we get a y-intercept of 2.

Now, you put this equation into point-slope form.

Subtract 2 from both sides of the equation.

[tex]y - 2 = -\frac{2}{3} x[/tex]

2 represents [tex]y_{1}[/tex], and the 0 will represent [tex]x_{1}[/tex]. This is because when you plug in 0 for x, you get 2 as the result.

So, the equation should be:

[tex]y - 2 = -\frac{2}{3} (x + 0)[/tex]

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Answer:

Norma should be offered the job.

Step-by-step explanation:

For Norma;

Population mean; μ = 67.5

Sample mean; x¯ = 84.5

standard deviation; σ = 10

Formula for the test statistic is;

z = (x¯ - μ)/σ

z = (84.5 - 67.5)/10

z = 1.7

For Rebecca;

Population mean; μ = 293

Sample mean; x¯ = 306.5

standard deviation; σ = 27

Formula for the test statistic is;

z = (x¯ - μ)/σ

z = (306.5 - 293)/27

z = 0.5

For Morgan;

Population mean; μ = 7.1

Sample mean; x¯ = 8.38

standard deviation; σ = 0.8

Formula for the test statistic is;

z = (x¯ - μ)/σ

z = (8.38 - 7.1)/0.8

z = 1.6

The person with highest z-score is Norma and as such he should get the job.
