Ans:x=2 and y=5

this is called the elimination method in linear graphs and simultaneous linear equations.

1. multiply each equation by suitable number so that they have the same coefficient but in this case, the coefficient is the same

2. subtract/add from the equations

3.solve the new equation

4.substitute the value of x/y into any equation above and solve it

Answer:

257.1

Step-by-step explanation:

first find area of square and then circles

square A=l^2

a=12^2

a=144

4 half circles=2 full circles

A of circle=pi*r^2

A=pi*6^2

A=36pi

=113.1

113.1+144

257.1

The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

Given that,

The dot plot shows predictions for the winning time in the​ 200-meter sprint.
The winner finished the race in 22.5 seconds.

We have to determine,

What is the greatest percent error among the​ predictions.

According to the question,
The true finishing time is 22.5 seconds.
The prediction furthest from this is 22.9 seconds.
This is a difference of 22.9 - 22.5 = 0.4 seconds. 

Divide this over the true time value to get prediction,
0.4/22.5 = 0.0177 = 1.77 (Approximately)

Move the decimal point to the right 2 spots to get to 1.773% (Approximately 1.8%).

Hence, The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

Hope my answer helps you.

Answer: B [tex]v=\pi 9^{2} h[/tex]

Step-by-step explanation:

to find volume use V=π r^2 h

if the diameter is 18 feet then the radius (r) will be half of that, 9 ft. So, to find the volume we'd just replace the r with 9 in the equation.

Answer:

B

Step-by-step explanation:

π(9)2hV = π ( 9 ) 2 h

Answer:

divide both sides of the equation by 0.15

I hope I help you in this ans and tq.

divide both sides of the equation by 0.15

Step-by-step explanation:

The first thing we need to do is REWRITE the middle term so that a x c = 2 x -24 = -48 AND the sum of b is 13. Please see below for the steps: 2x2 + 13x - 242x2 - 3x + 16x -24 x(2x - 3) + 8(2x - 3)  

Answer:

Step-by-step explanation:

(1) [tex]4x^2 + 36x + 80[/tex]

Let's factorise it:

[tex]4x^2[/tex] + 16x + 20x + 80

= 4x(x+4) +20(x+4)

= (4x+20)(x+4)

L of photograph = (4x+20)

B of photograph = (x+4)

Excluding the boundary/mat:

L = 4x + 20 - x = (3x + 20)

B = x - x + 4 = (4)

21.6 (6 is repeating)

Step-by-step explanation:

30 divided by 6 = 5

35 divided by 6 = 5.83 (3 is repeating)

5.83+5.83+5+5=21.6 (6 is repeating)

Recall that [tex]\cos \frac{\theta}{2}=\pm \sqrt{\frac{1+\cos \theta}{2}}[/tex].

Since [tex]-2\pi<a<-\pi[/tex], [tex]-\pi<\frac{a}{2}<-\frac{\pi}{2}[/tex], meaning [tex]c=\cos(a/2)<0[/tex].

[tex]c=-\sqrt{\frac{1+(1/8)}{2}}=-\frac{3}{4}[/tex]

Since [tex]0<b<|pi[/tex], [tex]0<\frac{b}{2}<\frac{\pi}{2}[/tex], meaning [tex]d=\cos(b/2)>0[/tex].

[tex]d=\sqrt{\frac{1+(1/8)}{2}}=\frac{3}{4}[/tex]

Answer:

Hickory, Delway, Midway, Ridgecrest

Step-by-step explanation:

So this question deals with negative numbers, which are like positive numbers but ordered backwards.  (Example:  -3, -2, -1, 0, 1, 2, 3)  

In that case, the correct order would be -10, -8, -2, 3.  Also known as Hickory, Delway, Midway, Ridgecrest.  

I hope this helped!  :)

Answer: 2 5/12

Step-by-step explanation:

1 17/12

17 - 12 = 5

2 5/12

Answer:

Step-by-step explanation:

-2(6x+36)-7x [tex]\leq[/tex] 23

First, multiply -2 with the terms on the parenthesis, using the distributive law

-12x-72-7x[tex]\leq[/tex]23

Then we gather similar terms, x with x, no x with no x

-12x-7x-72 [tex]\leq[/tex] 23

do -12x and -7x calculation

-19x-72[tex]\leq[/tex]23.

Since we want to find the X, we highlight it turning it into the first term

-19x[tex]\leq[/tex]23+72

then add 23 + 72

-19x[tex]\leq[/tex]95

then divide all members on the equation by -19

-19x/(-19)[tex]\geq[/tex]95/(-19)

x[tex]\geq[/tex] -5.

Now, 6x + 10 > 40

since we want to find x, we make it the first term of the inequation

6x>40-10

6x>30

divide all members by 6

x>5

Answer:

Step-by-step explanation:

To find the value of x, we need to divide 52 by 13.

13 multiplied by x = 52

x = 52 / 13

x = 4

So x is 4.

Answer:

10 ft

Step-by-step explanation:

Because if you look on the other side to the 6 you can tell its going to be bigger and it looks like it would be 4 more, and it wouldn't be ft squared because the rest arent like that so ft is the only one that matches the rest.

Recall that [tex]\sin 2x=2\sin x \cos x[/tex].

If [tex]\sin a=-4/5[/tex], then [tex]\cos a=-3/5[/tex].

[tex]c=\sin(2a)=2(-4/5)(-3/5)=24/25[/tex]

Using similar logic, [tex]d=120/169[/tex].

The value of the variables are,

c = - 24/25 and d = 120/169

From the given graph we can see that two functions,

y = sin (x) and y = sin (2x)

Now, (a, -4/5) lies on y = sin x so,

sin (a) = - 4/5

cos (a) = √(1 - sin² (a)) = √[1 - 16/25] = √9/25 = 3/5 [since cosine function is positive in between - π and 0]

Again (a, c) lies on the y = sin 2x so,

c = sin (2a) = 2 sin (a) cos (a) = 2 (-4/5) (3/5) = - 24/25

Further,

(b, 5/13) lies on y = sin x so,

sin b = 5/13

cos b = √(1 - sin² (a)) = √[1 - 25/169] = √144/169 = 12/13 [since cosine function is positive in between 0 and π/2]

Again, (b, d) lies on y = sin (2x) so,

d = sin 2b = 2 sin (b) cos (b) = 2 (5/13) (12/13) = 120/169

Answer: -3

Step-by-step explanation: You have to multiply 8*-2 resulting in -16*5 which’s equals -80 and divide 240 by -80 giving you -3

      The student forgot to divide the factors, 5 and 6, by the "a" value. In this case, that is 2. Then, simplify the fractions. Once we have these values, the numerator is the constant value and the denominator is the coefficient.

             5/2 = 5/2 ➜ (2x + 5)

             6/2 = 3 ➜ (x + 3)

     This student should have factored the expression as;

                 (2x + 5)(x + 3)

Answer:

(2x + 5)(x+3) = 0

Step-by-step explanation:

ac = 5 * 6 = 30
b = 5 + 6 = 11
Factorizing 2x² + 11x + 15,
2x² + 6x + 5x + 15 = 0
2x(x + 3) + 5(x+3) = 0
(2x + 5)(x+3) = 0

∴ x = [tex]\frac{-5}{2}[/tex], -3

(There was a mistake probably because the quadratic equation was considered with 1 as the coefficient as x², so the factorized equation was for x² + 11x + 30. You must take the coefficient of x² as 2 instead, according to the given equation.)

Recall that [tex]\cos(x)+\cos(y)=2\cos \left(\frac{x+y}{2} \right)\cos \left(\frac{x-y}{2} \right)[/tex].

[tex]\cos(12x)+\cos(16x)=0 \\ \\ 2\cos(2x)\cos(14x)=0 \\ \\ \cos(2x)\cos(14x)=0[/tex]

If [tex]\cos(2x)=0[/tex], then [tex]x=\frac{\pi}{4}, \frac{3\pi}{4}, \frac{5\pi}{4}, \cdots[/tex].

If [tex]\cos(14x)=0[/tex], then [tex]x=\frac{\pi}{28}, \frac{3\pi}{28}, \frac{5\pi}{28}, \cdots[/tex].

So, the three smallest positive [tex]x[/tex] intercepts are [tex]\frac{\pi}{28}, \frac{3\pi}{28}, \frac{5\pi}{28}[/tex].

Answer: 16

Step-by-step explanation:

Entire garden = 7 x 4 = 28m^2
Roses = 3 x 2 = 6m^2
2 Roses = 6 x 2 = 12m^2
Entire garden - 2 Roses = Tulips
So:
28 - 12 = 16 square metres

Answer:

16m2(it's meant to be squared so small 2 on top)

Step-by-step explanation:

1x2=2 (that is for the small turquoise box)

2x7=14(main big box)

2+14=16m2(same here with the 2)

Answer:695 pillow

Step-by-step explanation:

You have 395 pillows, and then 3 shipments of 100 pillows come in. 3 shipments x 100 pillows = 300 pillows

395 pillow + the 300 new ones = 695 pillows.

Answer: 695

Step-by-step Explanation: They started with 395 then got three shipments that add up to 300 so 395 + 300 = 600
