because it involves grouping

I'm probably answering this incorrectly but I'll try.

2.50(4) = 10

50(16) = 800

10 + 800 = 810

The extra is confusing me. Does it come from the very beginning of the trip or does it only count after the first 4 kilometers?

Answer:

16 cm^2

Step-by-step explanation:

Given

[tex]\triangle CAE[/tex] -- Bigger Triangle

[tex]\triangle CBD[/tex] -- Smaller Triangle

[tex]k = \frac{4}{3}[/tex] --- Scale factor

Area of CBD = 9

Required

Determine the area of CAE

The area of triangle CBD is:

[tex]A_1 = \frac{1}{2}bh[/tex]

[tex]\frac{1}{2}bh = 9[/tex]

The area of CAE is:

[tex]A_2 = \frac{1}{2}BH[/tex]

Where:

[tex]B = \frac{4}{3}b[/tex] and

[tex]H = \frac{4}{3}h[/tex]

The above values is the dimension of the larger triangle (after dilation).

So, we have:

[tex]A_2 = \frac{1}{2}*\frac{4}{3}b * \frac{4}{3} * h[/tex]

[tex]A_2 = \frac{1}{2}*\frac{4}{3} * \frac{4}{3} *b* h[/tex]

[tex]A_2 = \frac{1}{2}*\frac{16}{9} *b* h[/tex]

Re-order

[tex]A_2 = \frac{16}{9}*\frac{1}{2}* b* h[/tex]

[tex]A_2 = \frac{16}{9}*\frac{1}{2}bh[/tex]

Recall that:

[tex]\frac{1}{2}bh = 9[/tex]

[tex]A_2 = \frac{16}{9}*9[/tex]

[tex]A_2 = 16[/tex]

Hence, the area is 16 cm^2

Answer:

Step-by-step explanation:

Using the linear combination method, you can multiply the first equation by 2 and add the equations to get 20x = 10. Dividing both sides by 20, x = 1/2. To solve for y, substitute 1/2 for x in the equation 8x + 7y = 39 to get 4 + 7y = 39. Solving this equation, y = 5. Checking this in the other equation, 4(1/2) – 14(5) = –68 results in 2 – 70 = –68 or –68 = –68. The solution of the system shown is (1/2, 5). The system 8x + 7y = 39 and 20x = 10 is formed by replacing 4x –14y = –68 by a sum of it and a multiple of 8x + 7y = 39. Since 20(1/2) = 10, the system 8x + 7y = 39 and 20x = 10 also has a solution of (1/2, 5)

Answer:

1. trapezoid

2. 360°

Step-by-step explanation:

plz mark me brainliest, :)

Answer: 1: D 2: 360

Step-by-step explanation:

the shapes have the top and bottom two that are parallel and then the sides aren’t parallel

[tex] \tt \dashrightarrow 4y - 7 = 15[/tex]

[tex] \tt \dashrightarrow 4y = 15 + 7[/tex]

[tex] \tt \dashrightarrow 4y = 22[/tex]

[tex] \tt \dashrightarrow y = \cancel{\dfrac{22}{4}}[/tex]

[tex] \tt \dashrightarrow y = \dfrac{11}{2}[/tex]

[tex] \tt \dashrightarrow y = 5.5[/tex]

[tex] \large \underline{\boxed{\bf{y = 5.5}}}[/tex]

Hence, value of y = 5.5.

Answer: y = 5 ½ or y = 5.5

Step-by-step explanation:

4y - 7 = 15

Add 7 to both sides of the equation.

4y = 22

Divide both sides by 4

y = 5.5

Substitute y in the original equation.

4(5.5) - 7 = 15

22 -7 = 15

True.

Answer:

32

Step-by-step explanation:

80/100 = .8

.8 x 40 = 32 games won

Answer:

32

Step-by-step explanation:

80% of the games were won.

v. out of 40 games were won

Take 80% and divide it by 100

80%/100 = 0.8

Now multiply it by 40.

0.8 * 40 = 32

Answer: D) 1/32

Step-by-step explanation:

Step-by-step explanation:

-(3x+y=32)

3x-2y=17

-3x-y=-32

3x-2y=17

-3y=-15

y=5

3x+(5)=32

-5. -5

3x=27

x=9

Answer:

x=9

y=5

Answer:

x = 9

y = 5

Step-by-step explanation:

3x + y = 32...(1)

3x - 2y = 17....(2)

multiplying equation (1) by 2 we get,

6x + 2y = 64...(3)

Adding eq(2) and (3) we get,

6x + 2y = 64

+ 3x - 2y = 17

----------------------

9x. = 81

therefore, x = 81/9

therefore, x = 9

substituting value of x in eq( 1)

3 * 9 + y = 32

27 + y = 32

y = 32 - 27

y = 5

Answer: -23

Step-by-step explanation:

Answer:

85 points

Step-by-step explanation:

Let :

Total points made by team = x

Points made by the player :

2/5 of total = 2x/5

1/3 of the rest :

Points left = x - 2x/5= 3x /5

1/3 of 3x /5

1/3 * 3x / 5

= 3x / 15 = x / 5

Points made by rest of the players = 34 points

Hence, total points scored, x :

x = 34 + 2x /5 + x /5

x = 34 + 3x / 5

x - 3x/5 = 34

2x / 5 = 34

2x = 34 * 5

2x = 170

x = 170 / 2

x = 85

Total points scored by team = 85

Answer:

Step-by-step explanation:

7b + 8 < 100

subtract 8 from both sides

7b < 92

divide both sides by 7

b < 92/7 ≅ 13.1

Brian can buy at most 13 books.

Answer: You have to plug in the numbers.

So first let's plug in 13. 7*13+8=99

Now 15. 7*15+8=113

Now 18. 7*18+8=134

Lastly 20. 7*20+8=148

The answer is 13.

Answer:

x =97

Step-by-step explanation:

perpendicular (p) = 65

base (b) = 72

hypotenuse (h) = ?

We know by using Pythagoras theorem

h = √p² + b²

= √ 65² + 72²

= √9409

= 97

Step-by-step explanation:

also if it takes my dad five minutes to got milk and come back why has it been 7 years

Answer:

2 hours.

Step-by-step explanation:

You can see that it says it takes him 1 to walk a mile, so we can come up that once he walks another one, in total it took him 2 hours. Equation: h=hour, m=mile, m=h, 1x2.

Answer:

You would receive $510.08 in return.

Step-by-step explanation:

In order to find the answer, you can use the formula to calculate the future value:

FV=PV*(1+i)^n

FV=future value

PV= present value= 500

i= interest rate=0.03/12=0.0025 per month

n= number of periods of time= 8

Now, you can replace the values in the formula:

FV=500*(1+0.0025)^8

FV=500*(1.0025)^8

FV=510.08

According to this, the answer is that you would receive $510.08 in return.

Answer:

4480ft³

Step-by-step explanation:

formula: V=⅓Bh (B- base) (h-hight)

B=L×W, B=17.5×32= 560

h=24ft

V=⅓(L×W)h

V=⅓(560)24

V=⅓(13440)

13440÷3=4480ft³

Answer:

$600

Step-by-step explanation:

Omar spent $600.

Essentially, we divide his total number of points:

1800

by the amount earned

300

=

6

we take that and multiply by 100 (our amount needed to be spent to earn points) and boom, problem solved.
