Using the law of Sin

[tex]\frac{sinA}{a} \frac{sinC}{c}[/tex]

A=32°, a=?

C=90°, c= 30

[tex]\frac{sin32°}{a} = \frac{sin90°}{30}[/tex]

Answer:1, -1,3,-7

Step-by-step explanation:

For this case we must subtract the given matrices and find the values of a, b, c and d:

Subtracting term from term we have:[tex]a = 5-4 = 1\\b = 2-1 = 1[/tex]

We have that different signs are subtracted and the sign of the major is placed.

Answer:

x= 1.46497

Step-by-step explanation:

[tex]3^{x+1} = 15[/tex]

To solve this , first we convert the exponential form in to log form

[tex]if \ a^x=b \ then \ log_a(b)=x[/tex]

[tex]3^{x+1} = 15[/tex] becomes [tex]log_3(15)= x+1[/tex]

now we apply change of base formula to remove base 3

[tex]log_b(y)= \frac{log y}{log b}[/tex]

like that log_3(15) becomes

[tex]log_3(15)= \frac{log 15}{log 3}[/tex]

[tex] \frac{log 15}{log 3}= x+1[/tex]

2.46497=x+1

subtract 1 from both sides

x= 1.46497

Answer:

The value of x is 1.46.

Step-by-step explanation:

Given : Equation [tex]3^{x+1}=15[/tex]

To find : Solve for x using the change of base formula log base b of y equals log y over log b ?

Solution :

Equation [tex]3^{x+1}=15[/tex]

Applying the logarithmic property,

[tex]a^x=b\Rightarrow \log_a(b)=x[/tex]

[tex]3^{x+1}=15\Rightarrow \log_3(15)=x+1[/tex]

Applying change base formula in LHS,

[tex]log_b(y)= \frac{log y}{log b}[/tex]

[tex]\frac{log 15}{log 3}=x+1[/tex]

[tex]2.46=x+1[/tex]

[tex]x=2.46-1[/tex]

[tex]x=1.46[/tex]

Therefore, the value of x is 1.46.

Answer:

12lbs

Step-by-step explanation:

let x be the amount of apples you need, then:

x-0.14x= 10 8/25

0.86x = 10 8/25

(10 8/25) : 86 * 100 = x

x=12

Answer:

Total fresh apple needed = 12

Step-by-step explanation:

It is given that, While drying apple loses 14% of its weight

To find the fresh apple needed

Let x be the total fresh apple needed.

Apple loses 14% of its weight. Final we need 10 8/25 lbs of dried apple

x - 14x/100 = 10 8/25

0.86x = 10 8/25

0.86x = 258/25 = 10.32

x = 12

Here is the process I did:

2(6x+4)-6+2x=3(4x+3)+1

Step 1: Distribute the 2 to the numbers in the parentheses (6x +4) on the left side of the equation

6x(2)+4(2)-6+2x=3(4x+3)+1

12x+8-6+2x=3(4x+3)+1

Step 2: On the left side of the equation combine like terms

x's go with x's (12x and 2x):

(12x + 2x)+8-6=3(4x+3)+1

14x+8-6=3(4x+3)+1

normal numbers go with normal numbers ( 8 and -6):

14x+(8+(-6))=3(4x+3)+1

14x+2=3(4x+3)+1

Step 3: Distribute the 3 to the numbers in the parentheses (4x+3) on the right side of the equation

14x+2=4x(3) +3(3) + 1

14x+2=12x + 9 + 1

Step 4: On the right side of the equation combine like terms

normal numbers go with normal numbers ( 9 and 1):

14x+2=12x + (9 + 1)

14x+2=12x + 10

Step 5: Bring 2 from the left side to the right by subtracting it to both sides

14x+(2-2)=12x + (10-2)

14x = 12x + 8

Step 6: Bring 12x from the right side to the left by subtracting it to both sides

(14x - 12x) = (12x - 12x) + 8

2x = 8

Step 7: Isolate x by dividing 2 to both sides

[tex]\frac{2x}{2}  =\frac{8}{2}[/tex]

x = 4

Hope this helped!

Given equation is  one degree equation in x

Also it has only one variable 'x' hence it requires only one equation to solve for x  and the equation is given.

hence solution for x can be given as

2(6x+4)-6+2x =3(4x+3)+1

12x + 8 - 6 +2x = 12x + 9 + 1

12x +2 +2x =12x + 10

14x +2 = 12x +10

14x-12x = 10-2

2x = 8

Answer:

14 years old

Step-by-step explanation:

Assume Ray's sister's age is x.  

Ray's age is (x/2)+3, i.e (x+6)/2  

If Ray is 10yrs old,then  

(X+6)/2 = 10,  

x+6 = 20  

x = 14  

Therefore,Ray's siSter's /e is 14years

the distance is 13 length units

Final answer:

Using the Pythagorean Theorem, we calculate the distance between the points (5, -2) and (-7, 3) to be 13 units.

Explanation:

To find the distance between two points on a coordinate plane, we use the Pythagorean Theorem. Given points (5, -2) and (-7, 3), we calculate the difference in the x-coordinates and y-coordinates separately and then square each result.

d² = (5 - (-7))² + (-2 - 3)²

= (5 + 7)² + (-5)²

= 12² + (-5)²

= 144 + 25

= 169

Now, taking the square root of both sides to calculate the distance:

d = √(169)

= 13

Therefore, the linear distance between the two points, often denoted as 'PQ', is 13 units.

The measure of the major arc is found by calculating the circumference of the entire circle 2πr and then using the proportion that the angle of the major arc represents out of 360 degrees.

The measure of the major arc in a circle depends on the angle subtended by the arc at the center of the circle. If we define the angle Θ (theta) in degrees, that subtend the arc, the length of the major arc can be found by using the circumference of the entire circle, which is 2πr (where r is the radius), and the proportion of the circle that the major arc represents. Since the entire circle is 360 degrees, if the major arc corresponds to an angle Α, which is the complement of Θ (since Α + Θ = 360 degrees for the minor and major arcs together), the major arc length will be 2πr (Α/360). To summarize, if you're given the central angle of the minor arc or can otherwise determine the central angle for the major arc, you can use this proportion to calculate the arc length.

The solution is attached below

ANSWER

A. 17.31in²

EXPLANATION

The area of a sector is calculated using the formula:

[tex]Area = \frac{central \: angle}{360 \degree} \times \pi {r}^{2} [/tex]

From the diagram, the central angle is:

145° and the radius is 3.7 in.

We substitute the known values to get;

[tex]Area = \frac{145}{360 \degree} \times 3.14 \times {3 .7}^{2} = 17.3{in}^{2} [/tex]

The approximate area is 17.3 in² to the nearest tenth.

Step-by-step explanation:

We need to assume that the shape of the model is a cone or pyramid, something that tapers linearly to a point. Then its volume is given by the formula ...

V = 1/3Bh

where B is the area of the base, and h is the height. Filling in the given numbers, we have ...

586.7 = (1/3)B(22)

Dividing by the coefficient of B gives ...

B = 3(586.7)/22 = 80.0 . . . cm^2

The area of the base of the model is about 80.0 cm^2.

Ben drove 244 miles before he stopped for lunch.

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole.

As per the given data:

Ben has already driven 4/7 of the way to his friend's house before he stopped to eat lunch.

The total distance from Ben's house to his friend's house is 427 miles.

We have to find the Ben has already driven before he stopped to eat lunch.

Distance Ben's driven = 4/7 of the total distance

Distance Ben's driven = 4/7 × 427

Distance Ben's driven = 4 × 61 = 244 miles

Ben's already drove 244 miles before he stopped for lunch.

Hence, Ben drove 244 miles before he stopped for lunch.

Answer:

m∠4 = 40°

Step-by-step explanation:

Using the vertical angle theorem we can find that...

m∠6 ≅ m∠7

[tex]11x+8=12x-4 \\ \\ x=12[/tex]

[tex]11(12)+8 \\ 132+8 \\ 140[/tex]

Using this, we know that angle 6 and 8 are supplementary so...

m∠6 + m∠8 = 180°

140° + m∠8 = 180°

m∠8 = 40°

Then, we can use the corresponding angle theorem to find that...

m∠8 ≅ m∠4

m∠4 = 40°

the measure of angle 4 is 40

Adding like terms we get:

[tex]=7\left(\sqrt[3]{2}\sqrt[3]{x}\right)-6\left(\sqrt[3] {2}\sqrt[3]{x})-6\left(\sqrt[3]{x}\right\\=(\sqrt[3] {2}\sqrt[3]{x})-6\left(\sqrt[3]{x}\right)\\[/tex]

Answer:

E coli bacterium is 200times larger than Rhinovirus

Step-by-step explanation:

Length of a single Rhinovirus is 2×10^-8m

Length of E coli bacterium is 2×10^-6m

This shows that E coli is larger than Rhinovirus.

To determine the number of times the E. coli bacterium is larger than a Rhinovirus, we will divide the length of E coli bacterium by that of single Rhinovirus to have:

2×10^-6/2×10^-8

= 2×10^(-6-(-8))

= 2×10^-6+8

= 2×10²
