Answer:
x = 25
Step-by-step explanation:
Angles in a triangle add up to equal 180
Thus, 180 = 27 + 53 + 4x
We now solve for x
step 1 combine like terms
27 + 53 = 80
we now have 180 = 80 + 4x
step 2 subtract 80 from each side
180 - 80 = 100
80 - 80 cancels out
we now have 100 = 4x
step 3 divide each side by 4
4x / 4 = x
100 / 4 = 25
we're left with x = 25

Answer:
583.4 cm³
Step-by-step explanation:
We have the base dimensions, so enough information to find its area:
A = s²
A = (10 cm)² = 100 cm²
__
The height of the triangle is found by solving triangle AMV for the distance MV. That is found from the trig relation ...
Tan = Opposite/Adjacent
tan(68°) = MV/AM
The length of AM is half the diagonal of the square base, so is (10√2)/2 = 5√2. The length of MV is ...
MV = AM·tan(68°) = 5√2·tan(68°) ≈ 17.50
So, the volume of the pyramid is ...
V = (1/3)Bh
V = (1/3)(100 cm²)(17.50 cm) ≈ 583.4 cm³ . . . . volume of the pyramid
A grocery store sells avocados for $2.35 per pound how much would it cost to buy 7.4 pounds of avocados from this store
Answer: cost to buy 7.4 pounds of avocados from this store=$17.39
Step-by-step explanation:
Sale of avocados per pound in the grocery= $2.35
Sale of 7.4 pounds of avocados= $2.35 x 7.4 pounds =$17.39
Therefore, the cost to buy 7.4 pounds of avocados from this store=$17.39
6. If the measure of an arc is 68, what is the measure of its central angle?
Answer:
68
Step-by-step explanation:
Measure of arc = Measure of corresponding central angle
Thus, if the measure of an arc = 68, then the measure of its central angle also = 68

TYSM TYSM What is the surface area of the square pyramid?
I put a picture!
⬇️
Answer:
the surface area is 133cm.
7 x 7 is 49
7 x 6 is 42.
42 divided by 2 is 21.
21 x 4 is 84
So 84 + 49 is 133.

Step-by-step explanation:
seperate the prism into two. for the long rectanglular prism the formula is (6x2)x2 which is equal to 24. for the wider rectangular prism it's (4x4)x2=32. Add 32 and 24 together which makes the answer 56
What is 8x-2y=6 is slop-intercept form
Answer:
y= 4x -3
Step-by-step explanation:
1) add -8x at both members
8x - 2y - 8x = 6 - 8x
-2y = -8x + 6
2) divide both members by -2
y = 4x -3

Answer:
The second deal is better. It is $2.042 per gallon
Step-by-step explanation:
$11/5 and 51.05/25 are the deals.
Let's multiply the first deal by 5/5.
That is $55 per 25 gallons and the other deal is $51.05 per 25 gallons.
So the second deal is better.
Now lets divide 51.05 by 25 to find out how much dollars per gallon
51.05 / 25 = 2.042, so it is $2.042 per gallon.

The distance between D(-3,5) and E(x, 9) is 15. Find the value(s) of the
missing coordinate.
9514 1404 393
Answer:
x ≈ -17.457 or 11.457
Step-by-step explanation:
The distance formula can help.
d = √((x2 -x1)² +(y2 -y1)²)
Substituting given values, we have ...
15 = √((x -(-3))² +(9 -5)²)
225 = (x +3)² +16 . . . . . . . . square both sides
209 = (x +3)² . . . . . . . . . . . subtract 16
±√209 = x +3 . . . . . . . . . take the square root
-3 ± √209 = x . . . . . . . . subtract 3
x ≈ -17.457 or 11.457

1. What operation would you perform to express a measure given in the first unit as a measure in the second unit?
a) metres to centimetres _________________________
b) metres to millimetres __________________________
c) kilograms to grams ____________________________
d) litres to millilitres
2. Will each number be larger or smaller than the given number? Then fill in the blank.
larger smaller a) 3 m = ________ cm
larger smaller b) 28 cm = _________mm
larger smaller c) 2.4 km = _________m
larger smaller d) 485 mm = _________cm
larger smaller e) 35 cm = ____________m
larger smaller f) 2.4 m = _____________km
larger smaller g) 2495 mm = __________m
1.
a) metres to centimetres :
multiply length by 100
b) metres to millimetres:
multiply length by 1000
c) kilograms to grams:
multiply the mass value by 1000
d) litres to millilitres :
multiply volume by 1000
2.
a) 3 m = 3× 100 = 300 cm
b) 28 cm = 28 × 10 = 280 mm
c) 2.4 km = 2.4 × 1000
= 24 × 10^-1 × 10^3
= 24 × 10^2 =2400 m
d) 485 mm =485 / 10
= 485 / 10 ^1
= 485 × 10 ^-1
= 48.5 cm
e) 35 cm = 35 / 100
= 35 /10^2
= 35 × 10 ^ -2
= 0.35 m
f) 2.4 m = 2.4 / 1000
= 24 × 10 ^-1 / 10^3
= 24 × 10^-1 × 10 ^-3
= 24 × 10 ^ -4
= 0.0024 km
g) 2495 mm = 2495 /1000
= 2495 /10^ 3
= 2495 × 10 ^-3
=2.495 m

HOW TO DO THIS QUESTION
Answer:
see explanation
Step-by-step explanation:
The dot above the 5 indicates the 5 is repeating , that is
2.7555...
We require 2 equations with the repeating 5 placed after the decimal point.
let x = 2.7555,,, ( multiply both sides by 10 and 100 )
10x = 27.55... → (1)
100x = 275.55... → (2)
Subtract (1) from (2), thus eliminating the repeating 5
90x = 248 ( divide both sides by 90 )
x = [tex]\frac{248}{90}[/tex] = [tex]\frac{124}{45}[/tex]

4,7, 10, 13, 16, ....
Answer:
arithmetic sequence
Step-by-step explanation:
There is a common difference between consecutive terms , that is
d = 7 - 4 = 10 - 7 = 13 - 10 = 16 - 13 = 3
This indicates the sequence is arithmetic with common difference d = 3

Mean__
Median__
Mode__
Range__
Answer:
Mean= Summation /number of terms
= 48/8
=6.
Median
To do this
arrange all terms from smallest to biggest
That is
2,4,4,5,7,8,9,9
The two middle numbers are
5 and 7.
To get the median
add both and divide by 2
5+7 = 12... 12/2 =6
Median=6
Mode.... This is the number that appears most
Mode = 4 and 9.(Bimodal) Both appear equally.
Range: Highest - Lowest
= 9-2 =7.
Answer:
mean = 6 median = 6 mode 9 and 4 range = 7
Step-by-step explanation:
mean = 2+4+4+5+7+8+9+9÷ 8 = 6
median = 5+7÷2
mode = 9 and 4
range = 9-2=7
