Answer:
[tex] \\ \\ 90-60=30degree \\ \\ [/tex]
Answer:
15° and 75°
Step-by-step explanation:
The sum of the measures of complementary angles is 90.
Angle 1 measures x.
Angle 2 measures x + 60.
Their sum is 90.
x + x + 60 = 90
2x + 60 = 90
2x = 30
x = 15
x + 60 = 75
Answer: 15° and 75°

The side length of an equilateral triangle is 5 cm.
Find its perimeter
[tex]\rule{300}{1}\\\dashrightarrow\large\blue\textsf{\textbf{\underline{Given question:-}}}[/tex]
The side length of an equilateral triangle is 5 cm. Find its perimeter.
[tex]\dashrightarrow\large\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]
We are given that the triangle is equilateral.
"equi" means "equal" and "lateral" means "sides"
✯ So an equilateral triangle has 3 equal sides.
We are also given that one side is equal to 5 cm.
If one side is equal to 5 cm, and the triangle's equilateral, then the other two sides are equal to 5 cm.
◈ In order to find the perimeter of a shape, you should add all of its side lengths together.
✯ Now, we need to find the perimeter, which we can find using the following formula:-
[tex]\bold{Perimeter_{(triangle)}=a+b+c}[/tex]
Where a, b, and c are side lengths of the triangle.Now, we add them:-
[tex]\hookrightarrow\sf{P=5+5+5}[/tex]
So we conclude that the perimeter is equal to:-
[tex]\hookrightarrow\sf{P=15\:cm}[/tex]

Colin invests £2900 into his bank account.
He receives 3% per year compound interest.
How much will Colin have after 4 years?
Give your answer to the nearest penny where appropriate.
Answer:
£3263.98 (nearest penny)
Step-by-step explanation:
Compound interest formula
[tex]\sf A=P(1+\frac{r}{n})^{nt}[/tex]
where:
A = final amountP = principalr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsedGiven:
P = £2900r = 3% = 0.03n = 1t = 4Substituting given values into the formula and solving for A:
[tex]\implies \sf A=2900(1+\frac{0.03}{1})^{1 \times 4}[/tex]
[tex]\implies \sf A=2900(1.03)^{4}[/tex]
[tex]\implies \sf A=3263.975549[/tex]
Therefore, Colin will have £3263.98 after 4 years (to the nearest penny).
Answer:
$3264
Explanation:
[tex]\sf compound \ interest : P(1+\frac{r}{100} )^n[/tex]
"P" is principal, "r" is rate of interest, "n" is time (years)
Here given:
principal: £2900rate of interest: 3%time: 4 yearsAfter 4 years amount:
[tex]\rightarrow \sf 2900(1+\frac{3}{100})^4[/tex]
[tex]\rightarrow \sf 2900(1.03)^4[/tex]
[tex]\rightarrow \sf 3263.9755[/tex]
[tex]\rightarrow \sf 3264[/tex] (rounded to nearest whole number)
What are the measures of ∠CED and ∠BCE in the figure?
Answer:
∠CED = 70°
∠BCE = 134°
Step-by-step explanation:
Finding z :
∠EDC = ∠ABC (Alternate angles)8z = 64z = 8Finding ∠CED :
∠CED = 9z - 2∠CED = 9(8) - 2∠CED = 70°Finding y :
∠CDE = ∠BAC (Alternate angles)70 = 3y + 103y = 60y = 20Finding ∠BCE :
∠BCE = 7y- 6∠BCE = 7(20) - 6∠BCE = 134°Answer:
∠CED = 70°
∠BCE = 134°
Step-by-step explanation:
We don't know if AB and DE are parallel (since there are no arrows on these line segments), therefore we cannot use the Alternate Interior Angles Theorem at this point to definitively say that ∠CDE = ∠ABC.
Angles around a point sum to 360°
Angles on a straight line sum to 180°
⇒ ∠ACB + ∠BCE = 180
⇒ ∠ACB + (7y - 6) = 180
⇒ ∠ACB = 180 - (7y - 6)
⇒ ∠ACB = 180 - 7y + 6
⇒ ∠ACB = 180 - 7y + 6
⇒ ∠ACB = 186 - 7y
The interior angles of a triangle sum to 180°
⇒ ∠ACB + ∠CBA + ∠BAC= 180
⇒ 186 - 7y + 64 + 3y + 10 = 180
⇒ 260 - 4y = 180
⇒ 4y = 80
⇒ y = 20
Using the found value of y to find ∠BCE:
⇒ ∠BCE = 7(20) - 6
⇒ ∠BCE = 134°
Angles on a straight line sum to 180°
⇒ ∠DCE + ∠BCE = 180
⇒ ∠DCE + 134 = 180
⇒ ∠DCE = 46°
The interior angles of a triangle sum to 180°
⇒ ∠DCE + ∠CED+ ∠EDC = 180
⇒ 46 + (9z - 2) + 8z = 180
⇒ 17z + 44 = 180
⇒ 17z = 136
⇒ z = 8
Using the found value of z to find ∠CED:
⇒ ∠CED = 9(8) - 2
⇒ ∠CED = 70°

1. Make an organized list of the sample space for this experiment.
2. Which outcomes represent the event “at least two tails”?
3. What is the probability that there will be at least two tails
I will give brainliest if I see a answer labeled like this 1., 2., 3.,
I can only give brainliest if 2 people answer
Thanks so much! (๑>◡<๑)
Step-by-step explanation:
1.
when 3 coins are flipped the following outcomes are possible
h = heads, t = tails
h h h
h h t
h t h
h t t
t h h
t h t
t t h
t t t
yes, there have to be 8 options, because we have 3 positions with 2 possible outcomes. that means
2×2×2 = 2³ = 8 possibilities.
2.
at least 2 tails means 2 or 3 t in the list item :
h t t
t h t
t t h
t t t
3.
so, 4 out of the 8 possible outcomes. the probability is then therefore
4/8 = 1/2 = 0.5

a triangle that has 2 side lengths of 8 and 12 if x represents the length in inches on the third side, which inequality gives the range of possible values for x
Based on the triangle inequality theorem, the inequality that gives the range of possible values for x is: 4 < x < 20.
What is the Triangle Inequality Theorem?The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the length of the third side.
Therefore, the range of values that is possible for x would be:
12 - 8 < x < 12 + 8
4 < x < 20
The inequality is: 4 < x < 20

How many days would it take to breathe one billion times if you were
breathing at a rate of 12 times per minute?
Answer:
I think it would be 1,000,000.
Step-by-step explanation:
Let's begin with a correction: the verb in question is TO BREATHE; one instance of doing so is the noun BREATH.
12 times per minute; 60 minutes per hour; 24 hours per day; multiplying all of these gives some number of breaths per day. I'm going to call it B (you can calculate it).
Answer:
Step-by-step explanation:
12 / min
720 / hr
17,280 / day
6,307,200 / yr
Now divide 1,000,000,000 by 6,307,200 and you get 158 years

how do you solve x2 – 4 = 5 by graphing the related function
Answer:
see attached
Step-by-step explanation:
The related function we like to graph is the one that has the solutions as its zeros.
__
Subtract 5 from both sides.
x² -9 = 0
This is now in the form ...
f(x) = 0
The related function is then ...
f(x) = x² -9
and its zeros are the solutions to the original equation. The zeros (x-intercepts) of f(x) are x = -3 and x = 3.
__
Additional comment
The second attachment shows a graph of the given equation. Essentially, its graph is two points on the number line: x = -3 and x = 3.

The volume of the solid will be equal to V=64 Cubic inches.
What is volume?The space occupied by any solid object in the three-dimension is called as the volume.
Here we have 8 cubes in the solid object each cube has the side equal to 2 inches.
So the volume of one cube will be:
V=a³=2³=8 cubic inches
Since total number of the cubes are 8 so total volume will be:
V=8x8=64 cubic inches

prism volume = (area) * length
( 1/2 base * height) * length
Use pythagorean theorem to find height of triangular prism = 12
1/2 * 12 * 9 * 21 = 1134 km^3
Pyramid volume = 1/3 base * height =
