Answer:

Step-by-step explanation:

A = 12 ft²     - area of triangle

a = 4 ft, b    - legs of right triangle

c       - hypotenuse (third side of triangle)

A = ¹/₂ ab

12 =  ¹/₂•4•b

12 = 2b

b = 6 ft

from Pythagorean theorem:

a² + b² = c²

4² + 6² = c²

c² = 16 + 36

c = √52 = 2√13 ft

The perimeter:  P = a + b + c

P = 4 + 6 + 2√13 = (10 + 2√13) ft ≈ 10 + 7.21 = 17.21 ft

Yes

By tripling the height, you would triple the volume.

Also , By tripling the radius, you would increase the volume to nine times the original

Answer: A - 30 cubes

B - Volume of prism =  feet³

Step-by-step explanation: We are given that the dimensions of the rectangualr prism is,

Length =  =  feet

Width = 1 foot

Height =  =  feet

Thus, the volume of the prism = Length × Width × Height

i.e. Volume of the prism =  × 1 ×  =  feet³

Now, the side of the cube =  foot each.

Volume of the cube =  =  feet³

Answer:

x=6 and y=14

Step-by-step explanation:

First lets solve x

We substitute y for 0

So then this is how it turns out:

7*x+3*0=42

To find x you divide 42 and 7 and it becomes 6

Then lets solve y

We substitute x for 0

So then this is how it turns out:

7*0+3*y=42

To find y you divide 42 and 3 and it becomes 14.

THUS x=6 AND y=14

Answer:

There's a easier way to do this just like this you keep 1/6 then you change the division into multiplication and then seance you put the five which a 1 on the bottom like this 5/1 you flip it and it's 1/5 this strategy is called keep change flip so you keep 1/6 change division into multiplication and you flip 5/1 into 1/5 so it will end up like this 1/6x1/5=1/30

so it should be 16

Step-by-step explanation:

Hope this helps!

1 divided by 16 is 16

Answer:

[tex]\frac{20}{9}[/tex] or 2 [tex]\frac{2}{9}[/tex]

Step-by-step explanation:

1. Set up the problem : 2 ÷ [tex]\frac{9}{10}[/tex]

2. Since 2 is a whole number we can give it a denominator of 1, transforming the problem to: [tex]\frac{2}{1}[/tex] ÷ [tex]\frac{9}{10}[/tex]

3. Change the division sign into a multiplication sign.

[tex]\frac{2}{1}[/tex] × [tex]\frac{9}{10}[/tex]

4. Find the reciprocal by swapping the numerator and denominator on the second fraction

[tex]\frac{2}{1}[/tex] × [tex]\frac{10}{9}[/tex]

5. Multiply fractions

[tex]\frac{2}{1}[/tex] × [tex]\frac{10}{9}[/tex] = [tex]\frac{20}{9}[/tex] or 2 [tex]\frac{2}{9}[/tex]

Answer:

               •₁ same side interior angles  

               •₂ m∠1 = 78°,  m∠2 = 102°

               •₃ oars are parallel, conversed the same side interior angles theorem      

Step-by-step explanation:

•₁

The edge of the kayak is a transversal of lines created by oars. The angles are on the same side of transversal and between the oar-lines (inside the area between lines) so they are same side interior angles (or: consecutive interior angles)

•₂  

x = 10

m∠1 = 6x + 18 = 6•10 + 18 = 78

m∠2 = 9x + 12 = 9•10 + 12 = 102

•₃

The measures of angles 1 and 2 add to 180° (102+78=180) so they are suplementary angles. It means the oar-lines are parallel.

Based on:

Conversed the Same Side Interior Angles Theorem: If two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.

Answer:

Combining like terms mean to solve those terms whose have same bases

Answer:

like terms would be like 15 and 24 or 5x and 3x.

as long as they don't have a different variable or on a different side of the = sign they are considered like terms.

3 and 5x are not like terms

Answer:

Let's say the set of downs starts at the 20 yard line (maybe the kicking team kicked deep, the receiving team took a knee and so play starts at the 20).

Ok - we're at the 20. First down - they advance 5 yards. So we're now at the 25. We can write that mathematically as:

20

+

5

=

25

So the second play they get sacked deep and lose 6 yards. So we subtract 6:

25

−

6

=

19

So what's the change in yardage for the 2 plays? We are on the 19 and started at the 20, so we can write:

19

−

20

=

−

1

and this makes sense because we know we advanced 5 and fell back 6:

+

−

=

Answer:

for the third problem a = cb

for the 4th problem x = 5a + g

for the 2nd problem p = (q - 3r) / 4

for the first problem x = (-9 - z) / y

for the last problem: b = 15

A = 1/2 bh

75 = 1/2 b(10)

75 = 1/2 10b

multiply both sides by 2

150 = 10b

divide by 10 from both sides

15 = b

b = 15

Answer:

52 degrees

Step-by-step explanation:

Iscosceles trangle adds up to 180 degrees.

two sides are the same.

180-68= 112

112 divided by 2 = 52

the three sides are 52, 52, 68

The measure of one of the other angles would be x = 44 degree.

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

Isosceles triangles have two angles that are equal.

We are given that One angle of an isosceles triangle is known to be 68°.

Since the two equal angles are 68

We have the angles 68, 68, and an unknown angle x

Now add to 180

68+68+x = 180

136+x=180

x =180-136

x =44
