560 Square centimetres

Step-by-step explanation:

I'm not sure but I hope it is helpful and have a good luck

Answer:

416 sqr centimeters

Step-by-step explanation:

Area of Trapezoid

A = ([tex]\frac{a+b}{2}[/tex])h

a = 14cm

b = 38cm

h = 16cm

A = ([tex]\frac{14+38}{2}[/tex])(16)

A = 416 sqr centimeters

Recipe for 6 smoothies:

2 apples

3/2 of a lemon

4 peaches

Step-by-step explanation:

Recipe for 1 smoothie:

1/3 of an apple

1/4 of a lemon

2/3 of peach

A family of 6 arrives and they all want that smoothie.

Multiply every recipe for 1 smoothie by 6

Recipe for 6 smoothies:

6 × 1/3 of an apple

= 6/3 = 2 apples

6 × 1/4 of a lemon

= 6/4 = 3/2 of a lemon

6 × 2/3 of peach

= 12/3 = 4 peaches

Recipe for 6 smoothies:

2 apples

3/2 of a lemon

4 peaches

Answer:

D

Step-by-step explanation:

no explination

Answer:

k = -4

Step-by-step explanation:

First multiply 3 for both sides of the equation:

- 9 = k - 5

Then isolate k to get

k = -4

Answer:

K is equal to -14

Step by step:

3 x 3 = 9

We need 3 wholes.

5 + 9 = 14

14 - 5 = 9

K represents -14

Hope this helps!

Answer:

7.85

Step-by-step explanation:

You just put it in a calculator

Answer:

Step-by-step explanation:

A triangle has 180 degrees in total. One of the angles are 145 degrees, so we can subtract and get 35 degrees. Then, it says that the remaining angles are in a ratio 2:3. So, we would have:

[tex]2x:3x = 35 \\2x+3x = 35\\5x=35\\x=7[/tex]

Now that we know what x is, we can multiply that to our ratio:

[tex]2\cdot7=14 \text{ degrees for the first angle}\\3\cdot7=21 \text{ degrees for the second angle }[/tex]

Answer:

y = 1/2x + 10

Step-by-step explanation:

(y-11)/(14-11) = (x-2)/(8-2)

(y-11)/3 = (x-2)/6

2y-22 = x-2

2y = x + 20

y = 1/2x + 10

Let m = slope of the line.

m = (14 - 11)/(8 - 2)

m = 3/6

m = 1/2

We now have the slope and the slope is 1/2.

We plug the slope and one of the point into the point-slope formula.

Here is the point-slope formula:

y - y_1 = m(x - x/_1)

I will use the point (2, 11).

y - 11 = (1/2)(x - 2)

y - 11 = (1/2)x - 1

Now we solve for y by adding 11 to both sides of the equation.

y = (1/2)x - 1 + 11

Answer: y = (1/2)x + 10

Answer:

0=7

Step-by-step explanation:

Distribute

4−5=2(2+1)

4−5=4+2

Add 5 to both sides of the equation

4 − 5 = 4 + 2

4 − 5 + 5 = 4 + 2 + 5

Simplify Add the numbers

Add the numbers

4 = 4 + 7

Result

0=7

Answer:

Currently, scientists have identified at least three potential causes: parasites, pesticides, and poor nutrition of the bees.

Step-by-step explanation:

Answer:

it's A and C

(4, -8) and (-1,7)

Step-by-step explanation:

y = -3x + 4

A. works

x = 4

y = -8

-3(4) + 4

-12 + 4 = -8

B. doesn't work

x = 2

y = -10

-3(2) + 4

-6 + 4 = -2

C. works

x = -1

y = 7

-3(-1) + 4

3 + 4 = 7

D. doesn't work

x = -3

y = 4

-3(-3) + 4

9 + 4 = 13

it's A and C

(4, -8) and (-1,7)

Answer:

The mantle

Step-by-step explanation:

The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the mantle is the thickest layer, while the crust is the thinnest layer

Answer:

I think it's C if not D, but more likely C. Hope this helps, sorry if it doesn't.

Step-by-step explanation:

Answer:

C. 74

Step-by-step explanation:

add up all the numbers but not the value so you have 18 numbers. divide that by 2 and get 9. so 74 is between 73 and 78 so it divides the 18 numbers evenly into 9 and 9.

Answer:

C

Step-by-step explanation:

Clustered data emerge when the data from the entire sample can be grouped into a variety of different categories, refers to as clusters. Each cluster involves numerous observations, giving the data a “clustered” or “hierarchical” structure, with each observations encapsulated within the cluster.

Also, if we plot a series of numbers on a graph and we will see several of our dots gathered together, we have a cluster

From the above definition of clustered data the only option that is fitting into it is option C .

find area of 1 small bub

πr² = 3.14 × 3²

= 28.26 cm

area of 2 small bub

28.26 × 2 = 56.52 cm

area of big bub = area of 2 small bub

= 56.52

find radius by using formula

πr² = 56.52

r² = 56.52 ÷ 3.14

r² = 18

r = √18

r = 4.24 cm

round off to nearest cm

4.24 ≈ 4 cm

i think tanaka might be my favorite :)

Answer:

They do

Step-by-step explanation:

Both have 4 90 degree (right) angles.

A triangle has 3 sides and 3 angles. The angles of a triangle always add up to 180 degrees.The “angle” of a circle is 360 degrees – all the way around.

Hope this helps (Sometimes i think circles don't have any angles at all)

Answer:

Number 7 is 48

I think number 5 is 49 I'm not for sure about this one.

Step-by-step explanation:

Number 7:

Since it's a 90 degree angle, you just add 19 + 23 which gives you 42. Subtract 42 from 90 and it gives you 48, the value of the variable.

Number 5:

Now I'm not for sure about this one because of the number 12 pointing to the connecting point. So, I'd rather not say how I did this one before I get you confused when you learn about this in the future.

Answer: sinx= 8/11

Step-by-step explanation: Since it gives you the hypotenuse and opposite side use sine.

sin= opp/ hyp =  8/11

So... sinx = 8/11
