How many degrees is angle y
Answer:
y = 39°Steps:
w = 180 - (85+42) = 180 - 127 = 53°
y = 180 - (88+w)
y = 180 - (88+53)
y = 180 - 141
y = 39°
Answer:
y = 39
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of both triangles , then
x = 42 + 85 = 127
and
y + 88 = 127 ( subtract 88 from both sides )
y = 39

A person hikes 4 miles in 2.5 hours. Find the unit rate in miles per hour.
Answer:
60 miles per hour
Since d=rt, r = d/t = 420 miles/7 hours = 60 miles per hour
Step-by-step explanation:
Answer:
1.6 miles per hour
Step-by-step explanation:
Step one:
The unit rate is the number of miles in 1 hour
given
distance= 4 miles
time= 2.5 hours
so if he hike 4 miles in 2.5 hours
then he will hike x mile in 1 hour
cross multiply we have
x=4/2.5
x=1.6 miles per hours
Therefore the unit rate is 1.6 miles per hour
Answer: 60 miles per hour

Hi there!
[tex]\large\boxed{x = 16}[/tex]
.5x + 3 = 11
To begin, we can subtract 3 from both sides:
.5x + 3 - 3 = 11 - 3
.5x = 8
To cancel out the .5, we must multiply both sides by 2: (.5 × 2 = 1)
2(.5x) = 2(8)
x = 16.

A round tabletop is 6' in diameter. A sample jar of paint will cover 30 square feet. Is there enough paint to cover the tabletop?
Answer:
Yes, there is enough paint to cover the table top.
Step-by-step explanation:
We are told in the above question that the table top is round = circular
The area of a circle = πr²
Diameter = 6 feet
Radius = Diameter/2 = 6 feet/2 = 3 feet
Area of the table top= π × 3²
= 28.27 square feet
We are told that the a sample jar will cover 30 square feet.
Therefore, yes, there is enough paint to cover the table top.

answer choices:
A) 14.1 cm
B) 18.8 cm
C) 37.7 cm
D) 75.4 cm
Answer:
B. 18.8cm
Step-by-step explanation:
Circumference = π x Diameter
The given diameter here is 6cm and we need to use 3.14 for π so:
Circumference = 3.14 x 6
Circumference = 18.84 = 18.8 (1.d.p)
Therefore B is correct.

What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Desiree works at a dessert counter in the food court of a mall. The dessert counter sells cupcakes and cookies.
Each cookie costs $1.25 and assuming the cost of the cupcake is x.
∴ (1.25×12) + (8x) = 33.30.
15 + 8x = 33.30.
8x = 18.3
x = 2.28
