Need some help with the 5 by 5 puzzle. I keep getting stuck :(

Answer:

m<5 = 133

m<8 = 47

Step-by-step explanation:

m<3 = m<5 b/c of alt. interior angles

m<8 = x

180-133 = x

x = 47

Answer: 5.5

When you subtract 5.5 from 5.5 you get 0

Answer:

8+4

Step-by-step explanation:

Hope this is helpful ! have an amazing day... God Bless you :)

Answer:

8x + 4

Step-by-step explanation:

To answer, we have to make sure to hand out the 4 evenly so that each number or variable within the parentheses gets multiplied by 4:

4(2x + 1) = 8x + 4

As you can see, we multiplied each number inside by the number outside, and we got 8x + 4 as our answer.

Hope this helps :)

Answer:

a) 6/9 shaded.

b) About 67% is shaded. (66.6% repeating rounded to 67%)

Answer:

y=1/3x-6

Step-by-step explanation:

Answer:

y = -3x + 2

Step-by-step explanation:

y = mx + b is slope-intercept form, so you must find m and b

m = -3 since that is the slope

b = ? so use y=mx + b and substitute what you know

-4 = -3 (2) + b so -4 = -6 + b so solve for b since  2 = b

[tex](8 - 3a)(8 - 3a) \\ 8(8 - 3a) - 3a(8 - 3a) \\ 64 - 24a - 24a + 6a {}^{2} \\ 64 - 48a + 6a {}^{2} \\ 6a {}^{2} - 48a + 64[/tex]

Answer:

0.87

Step-by-step explanation:

y = ab^x

b is the rate of decay if it is between 0 and 1. Here, b = 0.87.

Answer: 0.87

Answer:

E, 297.1

Step-by-step explanation:

First, find the area of the triangle using the formula a= (bh) / 2

Base x height would be 16 x 12, which is 192

192 / 2 is 96 sq meters

Then, find the area of the circle using the formula a= Pi (r^2)

If the diameter is 16, the radius would be 8 because you divide by 2

8^2 is 64, 64 times Pi is approximately 201.1

Finally, add the areas together, 96 + 201.1 is 297.1 or E

Find what both expressions have in common

Step-by-step explanation:

e. >

f. <

g. =

h. >

i. =

j. <

.....

Answer:

e. >

f. <

g. =

h. >

i. =

j. <

Answer:

d=h (3+2)

Step-by-step explanation:

1- you cross multiply to bring d to the other side

h/1=d/3+2

2- this step will make this equation look like this

d=h (3+2)

* we kept 3+2 in brakets because h is multiplying the sum of 3+2

h (3+2) is the same as 5h

but they did not tell us to simplyify so we leave it as it is

3- now we have d as the subject

d=h(3+2)

Answer:

7.7 pallets of sod.

Step-by-step explanation:

A parallelogram-shaped field in a park needs sod. The parallelogram has a base of 27.5 meters and a height of 14 meters. The sod is sold in pallets of 50 square meters. How many pallets of sod are needed to fill the field?

Step 1

We find the area of a parallelogram

The formula is given as:

Base × Height

Hence:

The area is calculated as:

27.5 meters × 14 meters

= 385 square meters

Step 2

The sod is sold in pallets of 50 square meters. How many pallets of sod are needed to fill the field?

This is calculated as:

50 square meters = 1 pallet of sod

385 square meters = x

Cross Multiply

50 square meters × x = 385 square meters × 1 pallet

x = 385 square meters × 1 pallet/50 square meters

x = 7.7 pallets of sod.

Therefore, 7.7 pallets of sod are needed to fill the field.

Answer:

155

Step-by-step explanation:

Answer:

155⁰

Step-by-step explanation:

You can see that the figure above is a vertical angle. This means that :-

<a is congruent to <c

<b is congruent to <d

Since <a is 155⁰ and is congruent to <c, this means that <c 8s also 155⁰.

Hope this helps and I would appreciate if you give me the brainlist or not, thank you :) !!

Given:

The equation of a circle is:

[tex]x^2+y^2-x-2y-\dfrac{11}{4}=0[/tex]

To find:

The center of the circle and its radius.

Solution:

The standard form of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]          ...(i)

Where, (h,k) is center and r is the radius of the circle.

The given equation of the circle is:

[tex]x^2+y^2-x-2y-\dfrac{11}{4}=0[/tex]

Write the given equation in standard form of a circle.

[tex](x^2-x)+(y^2-2y)-\dfrac{11}{4}=0[/tex]

[tex]\left(x^2-x+\left(\dfrac{1}{2}\right)^2\right)+(y^2-2y+1^2)-\dfrac{11}{4}-\left(\dfrac{1}{2}\right)^2+1^2=0[/tex]

[tex]\left(x-\dfrac{1}{2}\right)^2+(y-1)^2-\dfrac{11}{4}-\dfrac{1}{4}-1=0[/tex]

[tex]\left(x-0.5\right)^2+(y-1)^2-\dfrac{12}{4}-1=0[/tex]

On further simplification, we get

[tex]\left(x-0.5\right)^2+(y-1)^2-3-1=0[/tex]

[tex]\left(x-0.5\right)^2+(y-1)^2-4=0[/tex]

[tex]\left(x-0.5\right)^2+(y-1)^2=4[/tex]

[tex]\left(x-0.5\right)^2+(y-1)^2=2^2[/tex]            ...(ii)

On comparing (i) and (ii), we get

[tex]h=0.5,k=1,r=2[/tex]

Therefore, the center of the circle is (0.5,1) and radius is 2 units.

Answer: -3/7

Step-by-step explanation:

Slope formula

M= -4-(-7) / 12-19

-3/7

Answer:

14units

Step-by-step explanation:

Let the vertices of a rectangle be A(3, 1), B(3, 5), C(6, 5), and D(6, 1).

Using the formula for calculating distance between two points;

AB =√(5-1)²+(3-3)²

AB = √4²

AB = 4

BC = √(5-5)²+(6-3)²

BC = √3²

BC =>3

CD = √(1-5)²+(6-6)²

CD = √(-4)²

CD = √16

CD = 4

AD= √(1-1)²+(6-3)²

AD = √3²

AD = √9

AD =3

Perimeter of the rectangle = AB+BC+BD+AD

Perimeter of the rectangle = 4+3+4+3

Perimeter of the rectangle = 14units

Answer:

40%

Step-by-step explanation:

If there are 1200 students in the school and 720 of them are boys that means 480 of them are girls.

I like to do cross multiply and divide so the equation for that would be  480/120 = ?/100

if you cross and multiply 480 by 100 you will get 48000 then if you divide that by 1200 you will get 40 as your missing value.

Im basically just saying 480/1200 = 40%

If you need further help there are plenty of you tube videos on how to cross  multiply and divide

Hope this helps
