What is the surface area of this figure?
Answer:
582 ft squared
Step-by-step explanation:
15*9*2 = 270
15*4*2 = 120
6*6*2 = 72
9*4*2 = 72
6*4*2 = 48
270 + 120 + 72 + 72 + 48 = 582

3) If the speed limit on a highway in the UK is 70 miles per hour and
it is 120km per hour in Canada, which country has the higher speed
limit for highways? What is the difference between them?
Step-by-step explanation:
for this we need to know the conversion rate between miles and kilometers :
1 mile = 1.60934 km
which means
1 km = 0.621371 miles
so,
70 m/h = 70×1.60934 km/h = 112.6538 km/h
compared to the 120 km/h limit in Canada, it is clear that the speed limit in Canada is higher.
the difference is
7.3462 km/h = 7.3462×0.621371 = 4.56471564 m/h
Cooper has a points card for a movie theater. • He receives 70 rewards points just for signing up. • He earns 8.5 points for each visit to the movie theater. • He needs at least 260 points for a free movie ticket. Which inequality can be used to determine v, the minimum number of visits Cooper needs to earn his first free movie ticket?
FIRST TO ANSWER CORRECTY WILL BE MARK AS BRILLIANT !!!!
Answer:
The correct answer is 70+8.5V > 260
Step-by-step explanation:
The equation of this is that instead of getting 260 points instantly he can get to 23 movies and earn the points each visits. So
8.5x23+70=265.5
Hence the correct answer is C

The price of a camera is $ 9810 inclusive of sales tax. If the rate of sales tax is 9%, find the printed price of the camera.
Answer:
$8927.1
Step-by-step explanation:
printed price is the actual price without including tax price
tax price= 9/100×9810
tax price= 0.09×9810= $882.9
printed price of the camera= 9810-882.9= $8927.1
In a test (+5) marks are given for every correct answer and (-2) marks are given for every incorrect answer. Smitha answered all questions and scored (-15) marks though he got 3 correct answers. How many incorrect answer had she attempted?
Any one help I will mark u as BRAINLIEST ANSWER if u help me plssssss! I will not accept wrong answer pls
Answer:
15 answers
Step-by-step explanation:
To solve this question we need to set up an equation.
Let's name the number of incorrect answers x.
We can set up an equation that's essentially:
(Points for correct answer)*(number of correct answers)+(points for incorrect answer)*(number of incorrect answers)=final score
When we plug in our numbers and variables it looks like this:
5(3)+(-2x)=-15
Simplify
15-2x=-15
Subtract 15 from both sides
-2x=-30
Divide both sides by -2
x=15
This means Smitha attempted 15 wrong answers, and that there were 18 questions in total.
The function C(t)=100*e^-0.000121t describes how to find the percentage of carbon-14, C(t), remaining in an object after t years. According to this information, what was the percentage of carbon-14 remaining in an object after 55 years? (Round your answer to the nearest hundredth.)
Answer:
99.34 years
Explanation:
Given function:
[tex]\sf C(t)=100*e^{-0.000121t}[/tex]
Insert t = 55:
[tex]\sf C(55)=100*e^{-0.000121(55)}[/tex]
Simplify following:
[tex]\sf C(55)=99.3367[/tex]
Round to nearest hundredth:
[tex]\sf C(55)=99.34[/tex]
What is the third term of the sequence described by the following explicit formula? an = 9 + (n - 1)8
Answer: Solve for a: a = [tex]\frac{8n+1}{n}[/tex]
Solve for n: [tex]n=\frac{1}{a-8}[/tex]
Step-by-step explanation:
solve for n: Move all terms to the left side and set them equal to zero. Then set each factor equal to zero.
solve for a: Divide each term in an = 9 + (n−1) ⋅ 8 by n and simplify.

Select two values that can replace \square□\square to make the equation true. \square=5. 40
Answer and Explanation:
x= 5.04
so, as this is a multiple choice question, the two values are
A - five ones and forty thousands
and
C - (5x1) + (4 x 1/100)
and as they both equal 5.04 (the value of "x"), those two would be the correct answers out of the four options given, hope this helps!!

Answer:
in terms of pi: 112.5pi mm squared
substituting pi for 3.14: 353.25 mm squared
Step-by-step explanation:
Surface area cone equation:
Πr2 + π*r*s
4.5^2 = 20.25pi
400 + 20.25 = 420.25
sqrt(420.25) = 20.5
20.25pi + 92.25pi = 112.5pi
Ryan and Patrick are eating together. They spent a total of
18 dollars on pizzas and calzones. Each pizza is 3 dollars
and each calzone is 2 dollars. They spent 2 minutes
eating each pizza and spent 5 minutes per calzone. It
took them 23 minutes to eat their food.
Help me
Answer:
Will you be my friend? please answer
Step-by-step explanation:
what do you need to find ?
the number of pizzas and calzones they were eating ?
if so :
p = number of pizzas
c = number of calzones
3p + 2c = 18
2p + 5c = 23
let's multiply the first equation by 2 and the second squadron by 3, and then subtract the second from the first :
6p + 4c = 36
- 6p + 15c = 69
-------------------------
0 -11c = - 33
c = 3
2p + 5c = 23
2p + 5×3 = 23
2p + 15 = 23
2p = 8
p = 4
so, they were eating 4 pizzas and 3 calzones.

A semi- circle has an area of 35cm . What is its diameter?
Answer:
Area Semicircle = 1/2 πr²where
r radius of semicircle
→ ½ * 22/7 * r² = 35
→ 11/7 * r² = 35
→ r² = 35*7/11
→ r² = 245/11
→ r² = 22.77
→ r = √22.77
→ r = 4.77
Therefore,
Diameter = 2*4.77
= 9.54 cm
