The measure of c is ???

Answer:

The other angle is 100

Step-by-step explanation:

A straight line is 180, and if one angle is 80, then 180-80=100, giving you your answer. ^^

Answer:

i think the answer will be 180-80?

Answer:

1.75x

Step-by-step explanation:

Let a be the area of the triangle

Let b be the area of the parallelogram

[tex]a = \frac{16 \times 9}{2} = 72 \: cm {}^{2} [/tex]

[tex]b = 30h \: cm {}^{2} [/tex]

Given that b is 5 times larger than a

b=5a

[tex]30h = 5(72)[/tex]

[tex]h = \frac{360}{30} = 12 \: cm[/tex]

Answer:

224mm²

Step-by-step explanation:formula for area of triangle = base x height x 1/2

8x10 = 80     80 / 2 = 40       40 x 4 = 160      area for square =base x height

the pyramid is comprised of four triangles and one square, all we need is to find the individual surface areas of the shapes that compose the pyramid

Answer:

(a) see attached

(b) Surface area = 224 mm²

Step-by-step explanation:

A square based pyramid is made up of a square at the base and 4 congruent triangles as the sides which meet at one point.

Area of a triangle = 1/2 × base × height

⇒ area of one triangle = 1/2 × 8 × 10

                                     = 40 mm²

Area of a square = s² (where s is the side length)

⇒ area of base = 8²

                         = 64 mm²

Total surface area = 4 × area of one triangle + area of the base

                               = 4 × 40 + 64

                               = 224 mm²

Answer:

[tex]x = 40.[/tex]

Step-by-step explanation:

[tex]if \: \: y = kx \: then \\ k = y \div x \: and \: x = y \div k \\ so \: k = 0.6 \: and \: x = 40 \: when \: y \: is \: 24.[/tex]

Answer:

Jade's work makes sense, Peter's does not.

Step-by-step explanation:

What's wrong with Peter's work:

Peter did not apply associative property correctly. You cannot change what is inside the parenthesis. He also shouldn't be using associative property to solve this equation because it just doesn't make sense!

Jade's work:

She applied distributive property correctly and multiplied each term in the parenthesis by 2. All of her processes are logical and make sense! I could go on, but everything is correct lol

Best of wishes mate!

Answer:

Jade because she followed the correct order of operations.

Step-by-step explanation:

Always remember your order of operations.

P - parentheses

E - exponents

M - multiplication

D - division

A - addition

S - subtraction

Please Excuse My Dear Aunt Sally is the common phrase used to remember though I find PEM-DAS just as easy to remember.

Answer:

1. 2(2w + w)

2. 2(2w) + 2(w)

Step-by-step explanation:

The formula to find the perimeter of a rectangle is [tex]2(l+w)[/tex], and we can easily apply it with this rectangle as 2(2w + w).

You can find another expression by simplifying 2(2w + w), which is 2(2w) + 2(w).

Answer:

x is 9

Step-by-step explanation:

since they are vertical angles, they are congruent. We make an equation putting each one behind the equal sign (7x+3=10x-24) and we solve.

Answer:

Non-mutually exclusive

Step-by-step explanation:

both events can happen simultaneously... 3 is an odd number, events A and B  have a common outcome.

It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.

===================================================

Explanation:

Ask yourself "is it possible to get a 3 and an odd number at the same time?"

The answer is "yes, because 3 is an odd number"

This is why they are non-mutually exclusive.

Mutually exclusive events cannot happen at the same time. In terms of a venn diagram, mutually exclusive events would be represented by two circles that do not overlap. The overlapping region is where the two events happen at the same time. An example of mutually exclusive events would be flipping a single coin to land on heads and tails at the same time.

Answer:

by technicality, both a and c are correct

a) 5.12 x 20 = 102.4

b) 10.95 x 9 = 98.55

c) 11.24 x 9 = 101.16

d) 12.18 x 8 = 97.44

Answer:

Step-by-step explanation:

Answer:

answer in picture

Step-by-step explanation:

Using the Central Limit Theorem, considering the higher sample size, the sample of 75 students, with a mean of 22.5, is a better representation.

It states that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard error [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

A higher sample size leads to a smaller standard error, hence the sample of 75 students, with a mean of 22.5, is a better representation.

Answer:

64 inches tall

Step-by-step explanation:

We know in 1 foot, there are 12 inches.

We can convert 5 1/3 feet to 16/3 feet.

To do this you convert 5 feet to 15/3 feet and add it to 1/3 feet.

So we now have 16/3 feet and we will multiply by 12  to find the number of inches she is.

16/3 * 12 = 64 inches tall

Answer:

√61

Step-by-step explanation:

using Pythagorean theorem,

h²+b²=hy²

h²+b²=hy²4²+2²=hy²

h²+b²=hy²4²+2²=hy²16+4=20

h²+b²=hy²4²+2²=hy²16+4=20hy²=20

therefore in radical form, Hy=√20

with the same theorem;

h²= hy²-b²

b² is initially given as (√20)²

hy² is given as 9²

h²=9²-(√20)²

h²=81-20

h²=61

h=√61
