Answer:

∠A = 58°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ACD is an exterior angle

∠A and ∠B are the opposite interior angles, thus

∠A + 80 = 138 ( subtract 80 from both sides )

∠A = 58°

Answer:

The correct answer is option A. 18x + 15

Step-by-step explanation:

It is given an expression in variable x,

5(4x + 3) - 2x

To simplify the given expression

5(4x + 3) - 2x = (5 * 4x) + (5 * 3) - 2x   (open the bracket)

  = 20x + 15 - 2x

  = 20x - 2x + 15

  = 18x + 15

Therefore the correct answer is 18x + 15

The correct option is option A.  18x + 15

Well in opinion, i think "rolling a standard number cube and getting an even number"

Answer:

Both events have the same likeliness of happening.

Step-by-step explanation:

A number cube has 6 numbers and 3 of them are even so the probability of rolling an even number is 3/6, which is 1/2. A coin has two sides, so the probability of flipping a coin heads up is 1/2. Rolling an even number on a number cube and flipping a coin heads up both have a 1/2 probability.

Answer: There are 150 bars in a case, and 2 cases per day are used (or 300 bars), Thus, in 7 days you would use 7 x 2 or 14 cases, or 2100 bars.

Step-by-step explanation:

Answer:

14 cases of soap bars.

Step-by-step explanation:

In one case of soap bars there is = 150 bars

You use amount of soap bars per day = 300

You need to order to have enough for 7 days  = 300 × 7 = 2100 bars

150 bars ⇒ 1 case

2100 bars ⇒ [tex]\frac{2100}{150}[/tex] = 14 case

Answer:

B 2 2/3

Step-by-step explanation:

Triangles ADB and CDB are similar. Therefore similar parts can form a proportion.

AD/DB = DB/DC

AD = ?

DB = 4

DC = 6

x/4 = 4/6    Cross multiply

6x = 16

6x/6 = 16/6

x = 2 4/6 or x = 2 2/3

It's B

ANSWER

[tex]AD =2 \frac{2}{3}[/tex]

EXPLANATION

According the Altitude Theorem, the height of the triangle is equal to the geometric mean of the two segment it creates on the hypotenuse.

This implies that:

[tex] {4}^{2} =6 AD[/tex]

[tex]16 = 6 AD[/tex]

Divide both sides by 6.

[tex]AD = \frac{16}{6} [/tex]

Simplify

[tex]AD = \frac{8}{3} [/tex]

Change to mixed numbers

[tex]AD =2 \frac{2}{3} [/tex]

Answer:

see explanation

Step-by-step explanation:

Since the figures are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{8}{x}[/tex] = [tex]\frac{18}{6}[/tex] ( cross- multiply )

18x = 48 ( divide both sides by 18 )

x = [tex]\frac{48}{18}[/tex] = [tex]\frac{8}{3}[/tex]

AND

[tex]\frac{5}{y}[/tex] = [tex]\frac{18}{6}[/tex] ( cross- multiply )

18y = 30 ( divide both sides by 18 )

y = [tex]\frac{30}{18}[/tex] = [tex]\frac{5}{3}[/tex]

Answer:

see explanation

Step-by-step explanation:

Given

6x² + x - 1 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 6 × - 1 = - 6 and sum = + 1

The factors are + 3 and - 2

Use these factors to split the x- term

6x² + 3x - 2x - 1 = 0 ( factor the first/second and third/fourth terms )

3x(2x + 1) - 1(2x + 1) = 0 ← factor out (2x + 1) from each term

(2x + 1)(3x - 1) = 0

Equate each factor to zero and solve for x

2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - [tex]\frac{1}{2}[/tex]

3x - 1 = 0 ⇒ 3x = 1 ⇒ x = [tex]\frac{1}{3}[/tex]

Answer:

[tex]f^{-1}(x) = log_{12}(y)[/tex]

Step-by-step explanation:

We have the following function

y = 12^x, and we need to find the inverse function.

To find the inverse function we should solve the equation for "x". To do so, first, we need to:

1. Take the logarithm in both sides of the equation:

lg_12 (y) = log _12 (12^x)

(Please read lg_12 as: "Logarithm with base 12")

From property of logarithm, we know that lg (a^b) = b*log(a)

Then:

lg_12 (y) = x*log _12 (12)

We also know that log _12 (12) = 1

Then:

x = log_12(y).

Then, the inverse of: y= 12^x is:

[tex]f^{-1}(x) = log_{12}(y)[/tex]

Answer:

  [tex]2a^{\frac{5}{2}}-4a^{-\frac{1}{2}}[/tex]

Step-by-step explanation:

It looks like you want to expand the expression ...

  [tex]\sqrt{a}\left(2a^2 -\dfrac{4}{a}\right)[/tex]

Use the distributive property and rules of exponents.

  [tex]=2a^{(\frac{1}{2}+2)}-4a^{(\frac{1}{2}-1)}\\\\=\boxed{2a^{\frac{5}{2}}-4a^{-\frac{1}{2}}}[/tex]

_____

The relevant rules of exponents are ...

  √a = a^(1/2)

  1/a = a^-1

  (a^b)(a^c) = a^(b+c)

To simplify the expression {x⁵}/{x²}, you subtract the exponents (5 - 2), resulting in x³, which is x cubed.

The given expression is {x⁵}/{x²}. To simplify this, we use the Division of Exponentials rule, which states that when dividing two expressions with the same base, you subtract the exponent of the denominator from the exponent of the numerator.

In this case, we subtract 2 from 5 (because the base is x and we have x to the power of 5 divided by x to the power of 2), giving us:

(x⁵⁻² which simplifies to (x³).

The simplified expression is therefore x cubed, or (x³).

Answer:

The weight of the three blades together is [tex]134\ g[/tex]

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=4\ in[/tex]

assume

[tex]\pi=3.14[/tex]

substitute

[tex]A=(3.14)(4)^{2}[/tex]

[tex]A=50.24\ in^{2}[/tex]

step 2

Find the area of the 3 blades

we know that

The area of the 3 blades represent a central angle of 60 degrees, so

its a 1/6 of the area of complete circle

[tex]A=50.24/6=8.37\ in^{2}[/tex]

step 3

Find the weight of the three blades together to the nearest gram

[tex](8.37\ in^{2})*(16\ g/in^{2})=134\ g[/tex]

Answer:

[tex]\frac{1}{6}[/tex]

Step-by-step explanation:

numbers less than 3 are 1 and 2, hence

P(number < 3 ) =[tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex]

P(tail ) and P(number < 3 )

= [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{3}[/tex] = [tex]\frac{1}{6}[/tex]

Answer:

Option d. [tex]f(x)=\$1,000(1+0.0355)^{x}[/tex]  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=x\ years\\ P=\$1,000\\ r=0.0355\\n=1[/tex]  

substitute in the formula above  

[tex]A=\$1,000(1+\frac{0.0355}{1})^{1*x}[/tex]  

[tex]A=\$1,000(1+0.0355)^{x}[/tex]  

Convert to function notation

[tex]f(x)=\$1,000(1+0.0355)^{x}[/tex]  

Answer:

35 cm

Step-by-step explanation:

To find the area of the bottom portion, you would use the formula for finding out a triangle (B*H*1/2) which is:

(4+4)*5.75*1/2=23

Then, for the top portion, one would find the area of the triangles on the sides (with two marks going through). Since along the middle is 8cm, and along the top is 4, we can see that there is 2cm on either side, so that is the length of the base of the triangle. To solve for the top triangles, you would do almost the same thing as the last one:

2*2*1/2=2

But since there's two identical triangles on either side, we can multiply that by two, which would bring it to 4.

That just leaves the rectangle that is left between the two triangles. To solve this, it's just B*H and luckily both of those are labeled for you already:

4*2=8  

Now, to find the total area, all you have to do is add up the areas of the different sections:

23+4+8=35 cm

Hope this helps!

Answer:

Step-by-step explanation:

n - 4, n - 2, n, n + 2, n + 4 - five odd consecutive integers

The equation:

(n - 4) + (n - 2) + n + (n + 2) + (n + 4) = 295         combine like terms

(n + n + n + n + n) + (-4 - 2 + 2 + 4) = 295

5n = 295        divide both sides by 5

n = 59

Answer:

D and E

Step-by-step explanation:

2 and 3 are verticle angles

1 and 4 add up to more than 180

angles 1 2 and 3 add up to more than 180

Based on the figure, the statements are true include;

D. m∠3 ≅ m∠4 = m∠1 ≅ m∠2

E. m∠1 ≅ m∠4 are vertical angles.

In Mathematics and Euclidean Geometry, the vertical angles theorem states that two (2) opposite vertical angles that are formed whenever two lines intersect each other are always congruent, which means being equal to each other.

By applying the vertical angles theorem to the lines, we have the following congruent angles:

m∠1 ≅ m∠4

m∠2 ≅ m∠3

Based on linear pair theorem, we have the following supplementary angles;

m∠3 + m∠4 = 180°

m∠1 + m∠2 = 180°

m∠3 ≅ m∠4 = m∠1 ≅ m∠2 (transitive property).
