Temp went from -16 to 7.What was the change in temperature

Answer:

b=22

Step-by-step explanation:

1 Remove parentheses.

b-11-29=-18b−11−29=−18

2 Simplify b-11-29b−11−29 to b-40b−40.

b-40=-18b−40=−18

3 Add 4040 to both sides.

b=-18+40b=−18+40

4 Simplify -18+40−18+40 to 2222.

b=22b=22

Answer:

84

Step-by-step explanation:

The equation that models this situation is 1110 = 15x + 150 where x = cameras sold (note that this doesn't include the first 20 cameras, we'll add those on at the end). Let's solve for x!

1110 = 15x + 150

960 = 15x

x = 64 so the answer is 64 + 20 = 84 cameras.

Answer:

x =-15

Step-by-step explanation:

[tex]8x-9x = \frac{150}{10} \\\\\mathrm{Add\:similar\:elements:}\:8x-9x=-x\\-x=\frac{150}{10}\\\\\mathrm{Divide\:the\:numbers:}\:\frac{150}{10}=15\\-x=15\\\\\mathrm{Divide\:both\:sides\:by\:}-1\\\frac{-x}{-1}=\frac{15}{-1}\\\\Simplify\\x=-15[/tex]

Answer:

78 Words per minute

Step-by-step explanation:

A unit rate is simply comparable to an average.  Given this, we can say the following:

Unit_Rate = 3666 Words / 47 minutes

Unit_Rate = 78 Words per minute

Answer:

f(x) * g(x)

Step-by-step explanation:

Hours worked per week = 45 hours

Weekly salary = $850 plus ;

3.5% commission on sales above $6,500

Given the functions :

f(x) = 0.035x and

g(x) = x - 6,500

and the fact that Joe’s dad sold enough this week to earn commission, which composition function represents Joe’s dad’s commissions ?

Commission = 3.5 / 100 = 0.035

Let his sales for the week = x ; since his sales exceeds 6,500

Hence, sales on which commission is payable is x - 6,500

Hence, commission for the week :

0.035 × (x - 6,500)

f(x) = 0.035 ; g(x) = (x - 6,500)

Composition function:

f(x) * g(x)

Answer:

Reliability= 149.94

Step-by-step explanation:

Field data have indicated that Unit A has a failure rate of 0.0004 failure per hour.

Reliability per hour=1- failure rate

Reliability per hour= 1-0.0004

Reliability per hour= 0.9996

Reliability= rate if reliability * number of hours

Rate of reliability= 0.9996 per hour

Number of hours= 150 hours

Reliability= 0.9996*150

Reliability= 149.94

Answer:

The answer is below

Step-by-step explanation:

The relative frequency is the proportion of a class or interval within a category. It is represented by the formula:

Relative frequency = frequency / total frequency

The percent frequency is the relative frequency expressed in percentage, it is given by the formula:

Percent frequency = Relative frequency × 100%

Using the formulas above, the table is filled:

The total frequency = 39

Class           Frequency     Relative frequency         Percent frequency

12 - 14                  2                  2/39 = 0.0513              0.0513 × 100% = 5.13%

15 - 17                  8                  8/39 = 0.2051              0.2051 × 100% = 20.51%

18 - 20                 11                 11/39 = 0.2821              0.2821 × 100% = 28.21%

21 - 23                  9                 9/39 = 0.2308             0.2308 × 100% =23.08%

24 - 26                 9                 9/39 = 0.2308             0.2308 × 100% =23.08%

Class           Frequency     Relative frequency         Percent frequency

12 - 14                  2                  0.0513                          5.13%

15 - 17                  8                  0.2051                          20.51%

18 - 20                 11                 0.2821                          28.21%

21 - 23                  9                 0.2308                          23.08%

24 - 26                 9                 0.2308                          23.08%

Answer:

[tex]\sec^2(\theta)=\frac{25}{16}[/tex]

Step-by-step explanation:

Recall what the relationship between cosine and secant:

[tex]\sec(\theta)=\frac{1}{\cos(\theta)}[/tex]

In other words, secant is the reciprocal of cosine.

So, if we know cosine, we only need to find its reciprocal to find secant.

We are given that cosine is:

[tex]\cos(\theta)=\frac{4}{5}[/tex]

Then secant must be:

[tex]\sec(\theta)=\frac{5}{4}[/tex]

So:

[tex]\sec^2(\theta)=(\frac{5}{4})^2[/tex]

Square:

[tex]\sec^2(\theta)=\frac{25}{16}[/tex]

Answer:

Option (3). EF

Step-by-step explanation:

From the figure attached,

Plane defined by EAB can be represented by the face EABF of the square prism also.

Similarly, plane EFG can be represented by the face EFGH of the prism.

Now these sides EABF and EFGH are joining each other at the edge EF of the cuboid.

Therefore, intersection of the given planes is EF.

Option (3) will be the answer.

Answer:

Addition Property of Equality

Step-by-step explanation:

So we had:

[tex]3x-2=7[/tex]

And then we got:

[tex]3x=9[/tex]

We did this by adding 2 to both sides of the equation. When we added 2, the left side cancelled and the right side equated to 9:

[tex](3x-2)+2=(7)+2\\3x=9[/tex]

Since we added 2 to both sides, this is an example of the addition property of equality.

Answer:

[tex]Per\ Capita = 64[/tex]

Step-by-step explanation:

Given

[tex]Books = 2.7 * 10^3[/tex]

[tex]People = 42[/tex]

Required

Determine the per capita

The per capita is calculated by dividing number of books by people as follows;

[tex]Per\ Capita = \frac{Books}{People}[/tex]

Substitute 2.7 * 10^3 for books and 42 for people

[tex]Per\ Capita = \frac{2.7 * 10^3}{42}[/tex]

[tex]Per\ Capita = 64[/tex] (Approximated)

Hence, the per capita is 64

Answer:

[tex]y=(x-3)^{2} -25[/tex]

Step-by-step explanation:

The standard form of a quadratic equation is [tex]y=ax^{2} +bx+c[/tex]

The vertex form of a quadratic equation is [tex]y=a(x-h)^{2} +k[/tex]

The vertex of a quadratic is (h,k) which is the maximum or minimum of a quadratic equation. To find the vertex of a quadratic, you can either graph the function and find the vertex, or you can find it algebraically.

To find the h-value of the vertex, you use the following equation:

[tex]h=\frac{-b}{2a}[/tex]

In this case, our quadratic equation is [tex]y=x^{2} -6x-16[/tex]. Our a-value is 1, our b-value is -6, and our c-value is -16. We will only be using the a and b values. To find the h-value, we will plug in these values into the equation shown below.

[tex]h=\frac{-b}{2a}[/tex] ⇒ [tex]h=\frac{-(-6)}{2(1)}=\frac{6}{2} =3[/tex]

Now, that we found our h-value, we need to find our k-value. To find the k-value, you plug in the h-value we found into the given quadratic equation which in this case is [tex]y=x^{2} -6x-16[/tex]

[tex]y=x^{2} -6x-16[/tex] ⇒ [tex]y=(3)^{2} -6(3)-16[/tex] ⇒ [tex]y=9-18-16[/tex] ⇒ [tex]y=-25[/tex]

This y-value that we just found is our k-value.

Next, we are going to set up our equation in vertex form. As a reminder, vertex form is: [tex]y=a(x-h)^{2} +k[/tex]

a: 1

h: 3

k: -25

[tex]y=(x-3)^{2} -25[/tex]

Hope this helps!
