Convert the decimal to a fraction (please show your work if you can) and also I will give b if correct!

Answer:

obtuse triangle

Step-by-step explanation:

it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!

Answer:

[tex]\boxed {\boxed {\sf (5,-4)}}[/tex]

Step-by-step explanation:

We are given the equations:

[tex]3x+2y=7 \\y=3x-19[/tex]

Since we know what y is equal to, we can substitute that expression in for y in the first equation.

[tex]3x+2(3x-19)=7[/tex]

Distribute the 2. Multiply each term inside the parentheses by 2.

[tex]3x+(2*3x)+ (2*-19)=7[/tex]

[tex]3x+6x+-38= 7[/tex]

Combine the like terms (the terms with variables).

[tex]9x-38=7[/tex]

Since we are solving for x, we must isolate the variable. 38 is being subtracted and the inverse of subtraction is addition. Add 38 to both sides.

[tex]9x-38+38=7+38 \\9x=7+38\\9x=45[/tex]

Now x is being multiplied by 9. The inverse of multiplication is division. Divide both sides by 5.

[tex]9x/9=45/9\\x=45/9\\x=5[/tex]

Now we know what x is equal to and can substitute the value into the second equation.

[tex]y=3x-19[/tex]

[tex]y=3(5)-19[/tex]

Multiply.

[tex]y=15-19[/tex]

Subtract.

[tex]y= -4[/tex]

Coordinate points are written as (x,y). Therefore, the solution is (5, -4).

Answer:

If the bisectors of two adjacent angles are perpendicular to each other, are the angles then supplementary angles?

Suppose two angles ABC and CBD are x and y.

x+y = 180 deg.

The bisector of angle ABC (BE) and the bisector of angle CBD (CF) will form angle EBF = (x/2)+(y/2) = 180/2 = 90 deg.

Conclusion: If the angle bisectors of two adjacent angles are perpendicular to eaxh other, the adjacent angles are supplementary angle

Adjacent angles are when the 2 angles have a common vertex and a common arm.

if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles.

Then the sum of the 2 adjacent angles is a right angle - 90°.

When 2 angles add up to 90°, they are called a pair of complementary angles.

Given:

The scale factor is 1:12.

Dimension of model = 32 cm

To find:

The actual dimension in m.

Solution:

Let x be the actual dimension.

The scale factor is 1:12 and the dimension of model is 32 cm.

[tex]\dfrac{1}{12}=\dfrac{32}{x}[/tex]

On cross multiplication, we get

[tex]x=32\times 12[/tex]

[tex]x=384\ cm[/tex]

[tex]x=3.84\ m[/tex]             [tex][\because 1\ m=100\ cm][/tex]

Therefore, the actual dimension is 3.84 m.

The volume of the sphere is 22/ 336 cubic units

The formula for volume of a sphere is expressed as;

Volume = [tex]\frac{4}{3} \pi r^3[/tex]

Where;

Substitute the values into the formula;

Volume = 4/ 3 × 22/ 7 × (1/ 4)³

Volume = 4/ 3 × 22/ 7 × 1/ 64

Multiply through

Volume = 88/1344

Volume = 22/ 336 cubic units

Answer:

the standard form of a linear equation required is B must be positive

Answer:

C=[tex]14\pi[/tex] or ≈43.96cm

Step-by-step explanation:

Start by figuring out the Area of the circle to get the radius (r)

Area (A)=153.86 cm

A=[tex]\pi r[/tex]²

153.86=[tex]\pi[/tex]r²

153.86÷[tex]\pi[/tex]=r²

49=r²

√49= r

r= 7cm

Next insert r=7cm into the Circumference equation of a circle

C=2[tex]\pi[/tex]r

C= 2×[tex]\pi[/tex]×7

C=14[tex]\pi[/tex] or C=43.96cm

Solve systems of equations by graphing

A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Example

[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]

Graph the equations in a coordinate plane

The two lines intersect in (-3, -4) which is the solution to this system of equations.

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

Step-by-step explanation:

The slope is the "rise" over the "run" of the line, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.

[tex]\frac{rise}{run}[/tex]

We can see that, on the graph, for every 3 units the line travels to the right, it travels 2 units up. Therefore, the rise is 2 while the run is 3.

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

Therefore, the slope of the line is  [tex]\frac{2}{3}[/tex].

Answer:

A = 20°

AC = 6.6

BC = 2.4

Step-by-step explanation:

Given:

B = 70°

C = right angle = 90°

AB = 7

Required:

A, AC, and BC

Solution:

✔️A = 180 - (90 + 70) (sum of triangle)

A = 20°

✔️Use trigonometric function to find AC:

Refernce angle = 70°

Opp = AC

Hypotenuse = 7

Apply SOH,

sin 70 = Opp/Hyp

sin 70 = AC/7

7 * sin 70 = AC

6.57784835 = AC

AC = 6.6 (nearest tenth)

✔️Use trigonometric function to find Bc:

Refernce angle = 70°

Adj = BC

Hypotenuse = 7

Apply CAH,

cos 70 = Adj/Hyp

cos 70 = BC/7

7 * cos 70 = BC

2.394141 = BC

BC = 2.4 (nearest tenth)

Step-by-step explanation:

Alright so we just need to find the percentage values of the discount and tax

What is 10%?:

x/800 = 10/100

8000 = 100x

x = 80

800 - 10%

800 - 80 = 720

What is 8%?:

x/800 = 8/100

6400 = 100x

x = 64

720 + 8%

720 - 64 = 784

Answer:

x=1/5y-2

Step-by-step explanation:

Step 1: Flip the equation

5x+10=y

Step 2: Add -10 to both sides

5x+10+-10=y+-10

5x=y-10

Step 3: Divide both sides by 5.

5x/5 =y-10/5

x=1/5y-2
