Solve the right triangle.
Round your answers to the nearest tenth

Answer:

3

Step-by-step explanation:

When you go from x=1 to x=3 you go up twice on the x-value. The y value also increases by 6 which means all you have to do is find the average.

6/2= 3

3 is the average increase between x=1 and x=3

Hope this helps!

Answer:

Missing angle is 55°

Step-by-step explanation:

Given :-

To find:-

Solution:-

We know that the sum of all angles in a triangle is 180°

and let the unknown angle be x

So ,

90°+35°+x = 180°

x = 180° - 125°

x = 55°

Answer:

x = - [tex]\frac{3}{2}[/tex] , x = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

4x² + 4x = 3 ← factor out 4 from each term on the left side

4(x² + x) = 3

to complete the square

add/subtract ( half the coefficient of the x- term )² to x² + x

4(x² + 2([tex]\frac{1}{2}[/tex] )x + [tex]\frac{1}{4}[/tex] - [tex]\frac{1}{4}[/tex] ) = 3

4(x + [tex]\frac{1}{2}[/tex] )² - 1 = 3 ( add 1 to both sides )

4(x + [tex]\frac{1}{2}[/tex] )² = 4 ( divide both sides by 4 )

(x + [tex]\frac{1}{2}[/tex] )² = 1 ( take square root of both sides )

x + [tex]\frac{1}{2}[/tex] = ± 1 ( subtract [tex]\frac{1}{2}[/tex] from both sides )

x = - [tex]\frac{1}{2}[/tex] ± 1

then

x = - [tex]\frac{1}{2}[/tex] - 1 = - [tex]\frac{3}{2}[/tex]

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

Answer:

#1: 4) D

#2: 1) 34.89 = 3 × C

#3: 4) 6y + 18

Step-by-step explanation:

#1

Using the distributive property:

3 × 5z = 15z

3 × -3 = -9

The correct expression is 15z - 9. Hence, D is the right option.

#2

You need to find the cost of each box.

3 × C = 34.89

34.89 ÷ 3 = 11.63

3 × 11.63 = 34.89

Hence, 1) is the right option.

#3

Using the distributive property:

6 × y = 6y

6 × 3 = 18

The expression is 6y + 18. Hence, 4) is the right option.

hope this helps!! p.s. i really need brainliest :)

Answer:

26 is a:

B. Whole number

D. Natural number

E. Integer

F. Rational number

Answer:

B, C, D, E, F or all options except A

Step-by-step explanation:

26 is not an irrational number since irrational numbers cant be put in fraction form while 26 can be. ex: 26/1, 52/2 and so on

26 is a whole number.

whole numbers are 0 1 2 3 4 and so on

26 is a real number

imaginary number example: sqrt of -2

natural numbers are numbers going from 1 to infinity

integers are any number that is not a decimal.

26 is rational since it's not irrational.

Answer:

~6.534653% of randomly selected a book from his bag (I don't know how many decimals you need)

Step-by-step explanation:

Basically you just do (66 (books) /1010 (total items)) * 100 to find your answer because out of the total 1010 items in that bag there is only 66 that are books so its (66/1010)*100 to find your answer, the *100 is added to find the percentage.

Answer:

£13,110.49

Step-by-step explanation:

(A) = P( 1 + r/n) ^nt

P(Principal) = £200 000

r(interest rate) = 1.6% = 0.016

The total amount been saved after 4 years is calculated as:

A = P( 1 + r/n) ^ nt

A = £200,000( 1 + 0.016/1)¹× ⁴

A =  £200,000(1.016)⁴

A =  £213,110.48991

A = £ 213,110.49

Claire will get approximately £ 213,110.49 within 4 years.

Answer:

A = 32 cm²

Step-by-step explanation:

the area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the height )

here b = 8 and h = 4 , then

A = 8 × 4 = 32 cm²

Answer:

Step-by-step explanation:

40 divided by 16 is 2.5

Answer:

327675

Step-by-step explanation:

the formula of the series is:

16

∑5*2^(n-1)

n=1

the formula for the sum of a geometric series is:

Sn=a(1-r^n)/(1-r)

plug in the values from above

n=16 a=5 and r=2 (values from the geometric function) so

Sn=5(1-2^16)/(1-2)

Sn=327675

Step-by-step explanation:

[tex]y=-3x-14[/tex] is a function as it has:

Linear equation in slope-intercept form:  [tex]y=mx+b[/tex]

where:

Therefore, for equation [tex]y=-3x-14[/tex]

So as the equation is a linear equation, its graph is a straight line.

Therefore, the only statement that is NOT true is D as the y-intercept is -14 (not 14).

The equation should look something like this.

[tex]\frac{u(3)}{3}[/tex]

Be careful with your use between cubing and multiplying; Cubing is multiplying the number by itself multiple times, while multiplying is like repeated adding, yet much easier.

In this case, if it says triple, I highly recommend multiplying by 3, which is what I did, it only looks different because it is in parentheses.

The coordinate of point G is its location on the coordinate plane

The area of the triangle would not remain the same

From the question, we have the following points

G = (4,-3) and

G = (4,3)

The above coordinates are two different points, and so they would make the triangle have different areas.

Hence, the area of the triangle would not remain the same

[tex]2*\left[\begin{array}{cc}8&4\\-2&3\end{array}\right]+\left[\begin{array}{cc}5&-2\\2&8\end{array}\right] = \left[\begin{array}{cc}21&6\\-2&14\end{array}\right][/tex]

Dilation involves changing the size of a figure

The dilation rule of a figure in the coordinate plane by a scale factor of 5 is (b) (x,y) [tex]\to[/tex] (5x,5y)

The scale factor (k) is given as:

k = 5

Assume the coordinates of the figure is (x,y)

The dilation rule would be:

(x,y) [tex]\to[/tex] k(x,y)

Substitute 5 for k

(x,y) [tex]\to[/tex] 5(x,y)

Expand

(x,y) [tex]\to[/tex] (5x,5y)

Hence, the dilation rule is (b) (x,y) [tex]\to[/tex] (5x,5y)
