Answers

Answer 1

Answer:

Answer is C

Step-by-step explanation:

Answer 2

From similar triangles ABC and ABD. DB/BC = DA/BA is the correct proportion.

Given that, ABC is a right triangle and BD drawn perpendicular to AC.

Consider triangles ABC and BCD,

∠C = ∠C (Reflexive property)

∠CBA = ∠CDB (Both measures 90°)

ΔABC similar to ΔBCD

BA/DC = CB/BD = BC/AC

Similarly,

Consider triangles ABC and ABD

∠A = ∠A (Reflexive property)

∠CBA = ∠ADB (Both measures 90°)

ΔABC similar to ΔABD

AB/AC = AD/AB = BD/BC

Therefore, DB/BC = DA/BA is the correct ratio.

On a coordinate plane, triangle A B C is shifted 4 units to the right and 2 units up to form triangle A prime B prime C prime. Identify the rule for the transformation shown in the figure that translates triangle ABC into triangle A'B'C'.

Answers

Answer:

(x, y) ⟶ (x + 4, y + 2)  

Step-by-step explanation:

If you shift a point four units to the right, x ⟶ x + 4.

If you shift it up two units, y ⟶ y + 2.

If you combine the two shifts into one transformation, the rule becomes

(x, y) ⟶ (x + 4, y + 2)

What is GCF (greatest common factor)?

GCF or greatest common factor is the common number which all the term has in a group of terms. It is the number which can divide each number of the group.

John has 24 blue, 96 green, 16 gray, 16 red and 32 white marbles. He wants to place them in identical groups without any marbles left over.

To find such identical groups, we have to find the greatest common factor of all these numbers. The factors of all the numbers are,

24=2×2×2×396=2×2×2×2×2×316=2×2×2×216=2×2×2×232=2×2×2×2×2

Here, the 2×2×2 is the common factor which is appears in all the terms.

[tex]2\times2\times2=8[/tex]

Thus, the greatest number of groups which John can make with marbles in order to place them in identical groups without any marbles left over is 8.

Solve for x in the diagram below.
(2x + 30°
40°
40°
т

Answers

Answer:

x = 35°

Step-by-step explanation:

assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °

i.e.

40 + (2x+30) + 40 = 180

40 + 2x+30 + 40 = 180

110 + 2x = 180  (subtract 110 from both sides)

2x = 180 - 110

2x = 70

x = 35

Answer:

x=35

Step-by-step explanation:

The 3 angles are on a straight line. A straight line is equal to 180 degrees. Therefore, the 3 angles are supplementary and add to 180 degrees.

40+2x+30+40=180

Combine like terms. Add all the terms on the left side without a variable.

2x+(40+30+40)=180

2x+110=180

We want to find out what n is. In order to do this, we have to get n by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

110 is being added to 2x. The opposite of addition is subtraction. Subtract 110 from both sides.

2x+110=180-110

2x=180-110

2x=70

x is being multiplied by 2. The opposite of multiplication is division. Divide both sides by 2.

2x/2=70/2

x=70/2

There are five more blue blocks than green blocks. Three times the number of green blocks, increased by double the number of blue, equals 95. How many of each colour are there?

Answers

Answer:

22 blue blocks

17 green blocks

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

There are five more blue blocks than green blocks.

So, the number of blue blocks (b) is equal to the number of green blocks (g) plus 5.

b = g+5

Three times the number of green blocks (3g), increased by double the (+2b) number of blue, equals 95.  

3g+2b =95

The system is  

b = g+5

3g+2b =95

Replacing b=g+5 in the second equation:

3g + 2 (g+5)=95

Solving for g:

3g +2g+10 =95

5g = 95-10

5g=85

g= 85/5

g= 17

Replacing g=17 in the first equation:

b = g+5

b = 17 +5

b=22

Equivalent expression:

a) -9

b) 3

c) 9

Step-by-step explanation:

The Property of Additive Inverse states that the summation of a number and it's Additive inverse = 0

An Additive inverse of a positive integer is a negative integer and vice versa.

For example:

5 -5 = 0

The additive inverse of 5 = -5

For the question above, we are asked to use the additive inverses and their properties to find the equivalent expressions.

a) 6 -(-3)

Additive inverse = - 6 + (-3)

= -6 - 3 = - 9

b) -6 -3

Additive inverse = 6 +(-3)

= 6 - 3 = 3

c) 6 - 3

Additive inverse = 6 + 3

= 9

d) -6 - (-3)

Additive inverse = -6 + 3

A line passes through (-5, -3) and is parallel to -3x - 7y= 10. The equation of the line in slope-intercept form is
Y=-3/7x-36/7
Y=-3/7x-6/7
Y=-7/3x-36/7
Y=-7/3x-6/7

Answers

Answer:

A.

Step-by-step explanation:

-3x-7y = 10

In slope - intercept form

y = -3/7x - 10/7

Since the lines are parallel so the slopes will be equal

m = -3/7

Now

Point = (x,y) = (-5,-3)

So, x = -5, y = -3

Putting in slope intercept form to find b

y = mx+b

-3 = (-3/7)(-5) + b

-3 = 15/7 + b

7b = -21-15

7b = -36

b = -36/7

Now the slope intercept form for the line is

What is the volume of the cone to the nearest tenth? A) 401.2 yd3 B) 421.4 yd3 C) 484.3 yd3 D) 536.2 yd3

Answers

Answer:

Option (D). 536.2 yd³

Step-by-step explanation:

Radius of the circular base of the cone = 8 yd

Height of the given cone = 8 yd

Formula for the volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]

Here r = radius of the circular base of the cone

h = height of the cone

By substituting the values of r and h in the formula,

V = [tex]\frac{1}{3}\pi (8)^2\times (8)[/tex]

   = [tex]\frac{1}{3}(512\pi )[/tex]

   = 526.165
