Answer:

Acyte, Scalene. please mark brainliest when its correct:)

Answer:

acute scalene

Step-by-step explanation:

The best guess is a acute scalene because the measure of the angles aren't shown. However, when you have both the measure of sides and angles, you can use the following image can help you classify triangles :

Answer:

To divide by a decimal, multiply the divisor by a power of ten to make the divisor a whole number. Then multiply the dividend by the same power of ten. You can think of this as moving the decimal point in the dividend the same number of places to the right as you move the decimal point in the divisor.

Answer:

60

Step-by-step explanation:

24 dividend by 4 equals 6.

this means 10% of the original price is 6.

6 times 10 equals 60

9,16,21 - not a right angle

10,24,26 - right angle

Answer:

(x - 1)² + 16

Step-by-step explanation:

Subtract 17 from both sides of the equation.

Use the formula (b/2)² to see which number you have to add to both sides.

Add 1 to both sides of the equation.

Factor the left side of the equation into a perfect square.

Add 16 to both sides of the equation.

(x - 1)² + 16 is the equation in standard form (x² - 2x + 17) rewritten by completing the square.

Answer:

T = 0.29p

Step-by-step explanation:

From the table Given :

We can obtain the uint cost per pound of wood :

Cost of 12 pounds of wood = $3.48

Cost per pound = Cost / weight

Cost per pound = $3.48 / 12 = $0.29

Hence, the proportional relationship cost, T in dollars and p pounds of wood is ;

Cost = unit cost per pound * number of pounds

T = 0.29 * p

T = 0.29p

Answer:

Part A

The height of the stack made of 8 containers is 19.6 cm

Part B

When the tower is 40.6 cm tall, the number of containers in the set are 22 containers

Part C

(Disagree) The height of a single container is 9.1

Step-by-step explanation:

The question relates to containers, stacked one inside the other such that the height increases by only the wider top edge of the containers

The given expression that gives the height of the stack is presented as follows;

1.5·c + 7.6

Where;

c = The number of containers in the stack

Part A

When there are 8 containers, we have;

h(8) = 1.5 × 8 + 7.6 = 19.6

The height of the stack made of 8 containers, h(8) = 19.6 cm

Part B

When the tower (height of the stack set) is 40.6 cm tall, we have;

h(c) = 1.5·c + 7.6 = 40.6

∴ The number of containers, c = (40.6 - 7.6)/1.5 = 22

When the tower is 40.6 cm tall, the number of containers in the set, c = 22 containers

Part C

Given that the height stack increases only by the thickness of the wider rim of each added container, we have;

The expression for the height of the stack , 1.5·c + 7.6, is the expression for a straight line equation, m·x + c

The thickness of each rim = The slope, of the line, m = The increase in height with number of containers = 1.5

The number of containers (The independent variable, x) = The number of stacked rims = c

The minimum height = The height of a single container = 1.5 × 1 + 7.6 = 9.1

Therefore, the height of a single container = 9.1 not 7.6

Answer:

x = − 4y + 16

x = − 6y + 24

Step-by-step explanation:

Let's solve for x.

x + 4y = 16

Step 1: Add -4y to both sides.

x + 4y + − 4y = 16 + − 4y

x = − 4y + 16

Answer:

x = − 4y + 16

Let's solve for x.

2x + 12y = 48

Step 1: Add -12y to both sides.

2x + 12y + − 12y = 48 + − 12y/2x= − 12y + 48

Step 2: Divide both sides by 2.

2x/2 = − 12y + 48/2x = − 6y + 24

Answer: x = − 6y + 24

Answer:

Expression: 2m + 2.50

Step-by-step explanation:

This is the expression that shows the total cost of Jose's trip.

The "2m" is because he has to pay $2 per each mile (m) he travels. The "+ 2.50" is because Jose has to pay $2.50 for the flag fall as well.

Answer:

$3

Step-by-step explanation:

You subtract the amount spent on dinner from the whole - 20 - 11.95 = 8.05

Then you subtract the amount remaining - 8.05 - 2.05 = 6

Then divide by two because they are both the same price - 6/2 = 3

Answer:

38mi

Step-by-step explanation:

to find the side you don't know: 7+5=12mi

to find the perimeter: 5+4+7+3+12+7= 38mi

Answer:

x = [tex]\frac{\sqrt{12} }{3}[/tex]12 = 8[tex]\sqrt{3}[/tex]

y = [tex]\frac{\sqrt{3} }{3}[/tex]12 = 4[tex]\sqrt{3}[/tex]

Let me know if you need some help simplifying the expressions or o the trig side of things

Step-by-step explanation:

I'm not sure if this is full out trig or recognizing special triangles, specifically 30-60-90 triangles.  Of course since one angle is 30 degrees and the other is 90 degrees this is a 30-60-90 triangle.

with 30-60-90 tringles  the basic guide is as follows.

The three legs will be referred to as the hypotenuse, short leg and long leg.  I will use H, S and L.  

H = 2S = [tex]\frac{\sqrt{12} }{3}[/tex]L

S = .5H = [tex]\frac{\sqrt{3} }{3}[/tex]L

L = [tex]\frac{\sqrt{3} }{2}[/tex]H = S[tex]\sqrt{3}[/tex]

If this is trig just break out the unit circle and SOH CAH TOA

So x is the hypotenuse, and y is the short leg and we know the long leg is 12, so we can use that.

to find the hypotenuse knowing the long leg we use H = [tex]\frac{\sqrt{12} }{3}[/tex]L and to find the short leg with the long leg you use S = [tex]\frac{\sqrt{3} }{3}[/tex]L.  now just plug in 12 for L

Answer:

j= 12

Step-by-step explanation:

j = 36/3

j = 12

Given:

The figure of a quadrilateral ABCD.

To find:

The supplement of angle ABC.

Solution:

We know that, two angles are called supplementary angles if their sum is 180 degrees.

[tex]\angle ABC+\angle BAC=110^\circ+40^\circ[/tex]

[tex]\angle ABC+\angle BAC=150^\circ\neq 180^\circ[/tex]

So, [tex]\angle BAC[/tex] is not a supplement of [tex]\angle ABC[/tex].

[tex]\angle ABC+\angle ADC=110^\circ+90^\circ[/tex]

[tex]\angle ABC+\angle ADC=200^\circ[/tex]

So, [tex]\angle ADC[/tex] is not a supplement of [tex]\angle ABC[/tex].

[tex]\angle ABC+\angle DAB=110^\circ+(40+30)^\circ[/tex]

[tex]\angle ABC+\angle DAB=110^\circ+70^\circ[/tex]

[tex]\angle ABC+\angle DAB=180^\circ[/tex]

So, [tex]\angle DAB[/tex] is a supplement of [tex]\angle ABC[/tex].

In the same way [tex]\angle ABC+\angle BDC\neq 180^\circ[/tex].

So, [tex]\angle BDC[/tex] is not a supplement of [tex]\angle ABC[/tex].

Therefore, the correct option is C.
