Answer:

it is an acute triangle

Step-by-step explanation:

angle M is 180 - 44 - 77 = 59

since all angles are less than 90 degree, thus is an acute triangle

Answer:

9.74 feet

Step-by-step explanation:

the formula for finding a hypotenuse is [tex]a^{2} + b^{2} = c^{2}[/tex]. We can rearrange that to get: [tex]c^2 - b^2 = a^2[/tex]. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.

It's an equation.

Answer:6.3 in.

Step-by-step explanation:

Given

Radius of sphere [tex]r=4\ cm[/tex]

When ball is immersed in beaker, it causes the water to flowout of beaker which is collected in the conical vessel

Such that amount of water equivalent to sphere volume is collected in it.

volume of ball

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

[tex]V_s=\frac{4\pi }{3}\times 4^3[/tex]

[tex]V_s=\frac{256\pi }{3}\ cm^3[/tex]

Now volume of water collected is in shape of cone then volume of cone

[tex]V_c=\frac{\pi }{3}r^2h[/tex]

and [tex]V_s=V_c[/tex]

[tex]\frac{256\pi }{3}=\frac{\pi }{3}(4)^2\times h\ quad [\text{h=height of cone formed}][/tex]

[tex]h=4^2=16\ cm\approx 6.29\approx 6.3\ in.[/tex]

Answer:

20

Step-by-step explanation:

We can use similar triangles

12/3 = x/5

x = 20

Answer:

VS = 20

Step-by-step explanation:

ST/SV = RT/QV

SV = ST×QV/RT

= 12×5/3

= 60/3

= 20

Hey!!

Solution,

Diameter=40 mm

Radius=40/2=20mm

Height=30mm

Volume of cylinder=?

Now,

Volume of cylinder=pi (r)^2 h

= 3.14*(20)^2*30

=3.14*400*30

=37,680 mm^3

So the right answer is of option A

hope it helps

Good luck on your assignment

__________________________________

Answer:

37,680 mm3

Steps:

Formula: Volume = Area * height

1:    = (pi/4)*D^2 * h

2:   = (pi/4)*(40)^2 * 30  

3:    = 37,680 mm3

Description:

We know that r is the radius and h is the height. So the

radius of the cylinder going to be r=40/2=20mm

Height of cylinder: 30mm

Meaning when you add up all the numbers answer will come as  37,680 mm3.  So a is the right answer for this question.

Answer: A.   37,680 mm3

Answer:

About 2.38 square feet of extra fabric: 1.25 of dark blue and 1.13 of light blue

Need $13.75 to complete template for white fabric

Step-by-step explanation:

Template requires 18 square feet of white, 20 square feet of light blue and 21 square feet of dark blue.

She has more than enough for both shades of blue fabric.

She needs 5.85 square feet more of white fabric

Since it is $2.35 per square feet of white fabric, 2.35 * 5.85 = $13.75.

It will cost her $13.75 for more white fabric

Hope this helps!

Answer:

4

Step-by-step explanation:

A square root has a positive and a negative square root

sqrt(16) = +4 and -4

Answer:

Jason Inherit a land with a 45% chance of having oil.

Step-by-step explanation:

 The probability of the land having oil is = P ( O) = 45 /100

The probability of the land having oil is= Q(O ) =55/100

The machine has an accuracy of 80%. This suggests that 8 out of 10 times the machine will give a wrong reading.

The probability of the correct reading is=  P(M)=80/100

The probability of the incorrect reading is=Q(M)=20/100

The case when the machine predicts there is no oil and there is indeed oil can be calculated:Probability=Probability of oil present  ×  probability of the incorrect reading

Probability=P(O) x Q(M)

Probability=45/100 x 20/100

Probability=9/100

The probability of the test predicting no oil in land and the land has oil is  0.09 or 9%

A

Step-by-step explanation:

The mode is the most frequent or most occurring value. The value 17 shows up the most times, at two times, so this is the mode. The value 19 is not even part of the given set of values, so you can immediately cross of choice A.

Side note: it is possible for a set to have more than one mode, and it's also possible to not have a mode at all.

Answer:

17

Answer:

We can split this into 2 "cases": 2x - 3 = 5 and 2x - 3 = -5 because you can find the absolute value of negative numbers as well. Solving the two cases we get x = 4, -1.

Answer:

x = 3/7y - 13/7

Step-by-step explanation:

7x-3y=-13

  +3y   +3y        Add 3y to both sides

7x = 3y - 13       Divide both sides by 7

x = 3/7y - 13/7

Answer:

1

Step-by-step explanation:

8(y^0) + (-7)(y^0)

Remove parentheses: (a)=a

= 8[tex]y^{0}[/tex]-7[tex]y^{0}[/tex]

Add similar elements: 8[tex]y^{0}[/tex]-7[tex]y^{0}[/tex]= [tex]y^{0}[/tex]

= [tex]y^{0}[/tex]

Apply rule [tex]a^{0}[/tex] = 1, [tex]\alpha \neq 0[/tex]

= 1

Answer:

y = 3/2x - 1

Step-by-step explanation:

Slope intercept form = y = mx + b

m = slope of the line = -2/3

y = -2/3x + b

Plug in (-2, -2) and the perpendicular line is

y = 3/2x - 1
