[tex]\bf \begin{array}{ccll} inches&cents\\ \cline{1-2} 17&51\\ 33&x \end{array}\implies \cfrac{17}{33}=\cfrac{51}{x}\implies 17x=33\cdot 51\implies x = \cfrac{33\cdot 51}{17} \\\\\\ x = 33\cdot \cfrac{51}{17}\implies x = 33\cdot 3\implies x = 99[/tex]

Final answer:

To find the cost of 33 inches of wire, we calculate the cost per inch from the given 17 inches costing 51 cents, which is 3 cents per inch, and then multiply by 33 inches to get a total cost of 99 cents.

Explanation:

The student is asking to determine the cost of 33 inches of wire based on the given rate of 17 inches costing 51 cents. To solve this, we can set up a proportion where we compare the given inches of wire to the given cost and then find the cost for the desired inches of wire.

Step-by-Step Calculation:

First, we determine the cost per inch of wire by dividing the total cost by the total length of wire: 51 cents ÷ 17 inches = 3 cents per inch.

Next, we multiply the cost per inch by the desired length of wire to find the total cost: 3 cents/inch × 33 inches = 99 cents.

Therefore, 33 inches of wire will cost 99 cents at the same rate.

Answer:

1/1000 or 1x10^(-3)

Step-by-step explanation:

0.001=1/1000 as a fraction

With a negative exponent?

You can write it into standard notation.

It's 1x10^(-3).

0.001 as a fraction with a negative exponent is 10⁻³.

To express the decimal 0.001 as a fraction with a negative exponent, we need to understand how negative exponents work with powers of ten. The decimal 0.001 is equivalent to the fraction [tex]\frac{1}{1000}[/tex], which can be written as [tex]\frac{1}{103}[/tex].

Using the concept of negative exponents, [tex]\frac{1}{103}[/tex] can be rewritten as 10⁻³. This is because a negative exponent indicates the inverse of the corresponding positive exponent. So, 0.001 = 10⁻³.

Summary in Steps:

Therefore, 0.001 equals 10⁻³ as a fraction with a negative exponent.

The water should fill the aquarium to 1.5 feet

Solution:

Given that the directions for the aquarium say that it should be filled with 9 cubic feet of water.

This means volume of aquarium is 9 cubic feet

Given that aquarium is 2 feet wide and 3 feet long

To find: Height of aquarium

Since a aquarium is in shape of cuboid, we can use the volume of cuboid formula

The volume of cuboid is given as:

volume of cuboid = [tex]l \times w \times h[/tex]

Where "l" is the length

w is the width

"h" is the height

Substituting the values, we get,

[tex]9 = 3 \times 2 \times h\\\\9 = 6 \times h\\\\h = \frac{9}{6} = 1.5[/tex]

Thus the height of aquarium is 1.5 feet

Answer:

m∠HMO=102°

Step-by-step explanation:

we know that

In a Rhombus the diagonals bisect the angles and opposite angles are equal

In this problem

Angles HMO and HTO are opposite angles

m∠HMO=m∠HTO

m∠HTM=(1/2)m∠HMO ----> because the diagonals bisect the angles and opposite angles are congruent

substitute the values

[tex](5x+6)\°=(1/2)(12x-6)\°[/tex]

solve for x

[tex]10x+12=12x-6\\12x-10x=12+6\\2x=18\\x=9[/tex]

Find the measure of angle HMO

m∠HMO=(12x-6)°

substitute the value of x

m∠HMO=(12(9)-6)=102°

The distance between A and B is l(AB) = 13 units

Step-by-step explanation:

Given:

let,

A ≡ ( x1, y1 ) ≡ ( 0, 12 )

B ≡ ( x2, y2 ) ≡ ( 5, 0 )

To Find:

Length AB = ?

Solution:

Distance Formula for the distance between the two points ( x1, y1 ) and ( x2, y2 ) we have,

[tex]l(AB) = \sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} )}[/tex]

On substituting the above values we will get,

[tex]l(AB) = \sqrt{((5-0)^{2}+(0-12)^{2} )}\\l(AB)=\sqrt{(5^{2} +(-12)^{2} } \\l(AB)=\sqrt{(25+144)}\\ l(AB)=\sqrt{169} \\l(AB)=13\ unit[/tex]

Therefore the distance between A and B is l(AB) = 13 units

Final answer:

The correct expression is '2(n + 9),' which corresponds to choice D and represents two times the sum of a number and 9.

Explanation:

The expression that represents the statement 'two times the sum of a number and 9' is D. 2(n + 9). This is because you first need to find the sum of the number (let's call it n) and 9, which is represented as (n + 9). Then, the statement says 'two times' which means you need to multiply that sum by 2, resulting in 2 × (n + 9).

We are testing the claim that males speak fewer words than females. With a p-value of 0.369, which is greater than the significance level of 0.05, we fail to reject the null hypothesis. Therefore, no significant evidence supports the claim that males speak fewer words than females.

The objective here is to test the claim that on average, males speak fewer words in a day than females. To do this, we compare two means using a hypothesis test for paired data.

The null hypothesis (H0) is that there is no difference between the mean number of words spoken by males and females. The alternative hypothesis (Ha) is that the mean number of words spoken by males is less than that spoken by females.

Since the p-value (0.369) is greater than the significance level of 0.05, we fail to reject the null hypothesis. This means we do not have significant evidence to support the claim that males speak fewer words than females.

A key takeaway from this is that the test statistic and p-value are critical elements in hypothesis testing. They determine whether or not you have significant evidence to reject the null hypothesis.

I have pictures to prove that they are the same in the graph as x + y = 11.

Hope this will help a lot more than the other answer.

Answer:

B.) f(x) = -x + 11

Step-by-step explanation:

Answer:

Let x = (the height of the fourth plant)

Then the average of the four heights will be:

(70+71+72+x)/4

Simplify it to (213+x)/4

This average has to be at least 73 inches. Meaning, it has to be greater than or equal to 73.

(I don't have the sign for greater/equal so I'll type >=)

(213+x)/4 >= 73

This is the inequality. Just solve for x, and you have the answer.

(213+x) >= 292

x >= 79

Another way: (I think it's easier to do it like this in my head)

You need average 73.

Look at the heights of the plants you have now: how far are they from 73?

The first is 3 less, the second is 2 less, and the third is 1 less.

The 'total deficit'' is 6.

So to make the average be 73, you need to cancel out the deficit by making an equal overage (by 6).

If you can only add one more plant... that plant has to be 6 inches higher than the average you want. So 73+6=79.

Step-by-step explanation:

4. 3x + 2y = 6

x-intercept = 2 ,  y - intercept = 3

5. 4x – 9y = 36

x-intercept = 9, y - intercept = -4

6. x + y = -3

x-intercept = -3, y - intercept = -3

8. x - 3y = 12

x-intercept = 12, y - intercept = -4

Step-by-step explanation:

To find the x-intercept we put y=0 in the equation and to find the y-intercept we put x = 0 in the equation

4. 3x + 2y = 6

Putting y = 0

[tex]3x + 2y = 6\\3x +2(0) = 6\\3x = 6\\\frac{3x}{3} = \frac{6}{3}\\x= 2[/tex]

5. 4x – 9y = 36

Putting y = 0

[tex]4x -9y = 36\\4x - 9(0) = 36\\4x = 36\\\frac{4x}{4} = \frac{36}{4}\\x = 9[/tex]

Answer:

f(x)=5-x

Step-by-step explanation:

The equation y + x = 5 in function notation is f(x) = 5 - x, done by isolating the dependent variable, y, and expressing it as a function of x.

The equation y + x = 5 can be rewritten in function notation by isolating the dependent variable, y, which is standard procedure in function notation. To isolate y, we need to subtract x from both sides of the equation. Thus, the equation y + x = 5 becomes y = 5 - x. In function notation, where y is typically written as f(x), this would become f(x) = 5 - x.

Step-by-step explanation:

both have equal chances

The required probabilities are 3/8 and 1/8 respectively.

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here: Jackie has 6 skirts and 2 dresses.

Total number of dresses=8

Thus the probability of picking a skirt is = 6/8

                                                                   =3/4

And the probability of picking a dress is =2/8

                                                             =1/4

Also, the probability of choosing either shoe is 1/2

Therefore the conditional probability that she chooses a skirt and brown shoes is = 3/4×1/2

              =3/8

Similarly Probability( dress+black shoes)=1/4×1/2

                                                                   =1/8

Hence, The required probabilities are 3/8 and 1/8 respectively.

Given

[tex]-10x+12i=20+3yi[/tex]

Two complex numbers are equal when they have equal real and imaginary parts.

Equate real parts:

[tex]-10x=20\\ \\x=-\dfrac{20}{10}=-2[/tex]

Equate imaginary parts:

[tex]12=3y\\ \\y=\dfrac{12}{3}=4[/tex]

Final answer:

The values of x and y that satisfy the given complex equation are x = -2 and y = 4, found by equating the real and imaginary parts respectively.

Explanation:

To find the values of x and y that satisfy the equation -10x + 12i = 20 + 3yi, we need to equate the real parts and the imaginary parts of the complex numbers on both sides of the equation.

For the real parts, we have:
-10x = 20
=> x = -2

For the imaginary parts, we have:
12 = 3y
=> y = 4

So the solution for the equation is x = -2 and y = 4.
