Find the surface area of the triangular pyramid.
a triangular pyramid - the base has side length 2.5 inches and height 2.2 inches and each face has height 5 inches
Answer:
31.25 in²
Step-by-step explanation:
Surface area of triangular pyramid
Perimeter, P = 4s = 4 * 2.5 = 10 inches
Lateral surface area = 0.5 * P * height = 0.5 * 10 * 5 = 25 inch²
The base area = s² = 2.5² = 6.25 inch²
Hence, surface are ao triangular pyramid ;
Lateral surface area + base area
= 25 inches + 6.25 inch²
= 31.25 in²
Just do one of them and I’ll know enough to do the rest.
Hope it helps.
If it helps then please mark it as the brainliest.
Thank you.
7. In a bay the time between high tide and low tide is approximately 6 hours. The first low tide is at 7 a.m. followed by a hide tide at 1 p.m. The depth of the water in the bay at low tide is 5 fathoms which rises to 9 fathoms at high tide. a) Sketch a graph of the depth of the water in the bay over time. Start your graph at 7 a.m. and graph at least on complete cycle. b) Write a function equation for your curve. Let t represent the number of hours after 7 a.m. c) How deep will the water be at 11 a.m?

A candy factory makes 292,827 candies each day. About how many candies will it make in two weeks?
Choose the best estimate.
4,180,0004 comma 180 comma 000
4,200,0004 comma 200 comma 000
4,102,0004 comma 102 comma 000
4,060,0004 comma 060 comma 000
Answer:
4,102,0004 comma 102 comma 000
Step-by-step explanation:
If it makes 292,827 candies in a day, to find the approximate value of candies produced in 2 weeks, you have to multiply 292,827 by 14, being 14 days in 2 weeks. But since this is just rounding, the easiest option is just to find the actual answer and see which one is closest.
Find all points on the curve y = cos x, 0 ≤ x ≤ 2π, where the tangent line is parallel to the line y = -x.
Answer:
90⁰
Step-by-step explanation:
y=cosx
y'= -sinx
eqñ of tangent is y=-x
slope of tangent =-1
we know...
slope of tangent = y' or derivative of y
-sin x = -1
sin x= 1
x = 90⁰
after a teacher handed out m packs of notebooks with c notebooks in each pack
Answer:
M/C
Step-by-step explanation:
So you divide the number of notebooks handed out (m) by the number of notebooks per pack (c) to get the number of packs.The number of packs is m/c

Explain why this common mistake is wrong. Many people might say that (2, 4) is an intercept of the equation 5x + 2y = 18.
Answer:
Step-by-step explanation:
(2,4) is point lying on the line represented by 5x + 2y = 18.
They are not intercepts.
x-intercept is point where the line crosses the x-axis and so, y-co ordinate at x-intercept is 0.
y-intercept is point where the line crosses they-axis and so,x-co ordinate at y-intercept is 0.
5x + 2y = 18
To find x-intercept, put y = 0 in the equation
5x = 18
x = 18/5
x = 3.6
To find y-intercept, put x = 0 in the equation
2y = 18
y = 18/2
y = 9
x-intercept : (3.6 , 0)
y-intercept :(0, 9)
Mark works 24 hours a week and earns £11.63.
Calculate Mark's weekly basic pay and then find his annual salary
Weekly pay = amount per hour x number of hours:
24 x 11.63 = 279.12
Annual salary = weekly pay x 52 weeks:
279.12 x 52 = 14,514.24
The relative frequency that the traffic lights will show GREEN at road works is 0.7. Estimate how many times they would be RED over the next 40 journeys?
Answer:
28 reds are expected over the next 40 journeys
Step-by-step explanation:
Here, we want to get the number of reds in the next 40 journeys
From the question, we have that the relative frequency is 0.7
Thus, for the number of reds, we have to multiply the relative frequency by the number of journeys
We have this as;
40 * 0.7 = 28

If Josie runs a 25-mile race in 5 hours and Greta runs a 18-mile race in 4 hours. Who runs at a FASTER pace?
Answer:
Josie because 25 miles in 5 hours is 5 miles every hour and Greta runs 4.5 miles evry hour
Step-by-step explanation:
Josie runs 25 / 5 = 5 mils per hour
Greta 18 / 4 = 4,5 miles per hour
Josie is FASTER
A car travels 384 kilometers in 4 hours. (with a constant speed) how much time will it take traveling at 144 kilometers?
Answer:
1.5 hours or 90 minutes
Step-by-step explanation:
384 km: 4 hours
divide both sides by 4
96 km: 1 hour
multiply both sides by 1.5
144 km: 1.5 hours
Answer:
it will take 1.5 hrs as u multiply 144 with 4 and divide by 384

Answer:
The area of the shape is 21.87 square feet.
Step-by-step explanation:
Assuming the indent on the right is a perfect semicircle, then you need only subtract the area of the semicircle from the area of the rectangle.
The rectangle is six feet on both directions, giving it an area of 36 square feet.
The circle then has a radius of 3 feet. The area of a circle is equal to πr², so in this case, π × 9. Using a pi value of 3.14, nine times that is 28.26. We only want half the circle's area though, giving us 14.13.
Now we can subtract that semicircle from the square giving us:
36 - 14.13 = 21.87
So the total area is 21.87 square feet.
An apartment manager would like to survey a sample of residents to determine whether there may be interest in building a pool what is the best way that the apartment manager could select he sanple
Answer: b. randomly select people from all residents of the apartment building.
Step-by-step explanation:
This issue at hand concerns all residents of the building so the apartment manager should randomly select people to participate in the survey from the entire population of all the residents of the apartment building.
Selecting only those who have children would not be representative of the whole population as there will be people with less or more children than 5 and some would not have children. Option C and D are wrong because only current residents should be included.
You deposit $150 into an account with an interest rate of 3%. After 5 years, how much interest have you earned?
if u earned $150 and had a rate of 3% if u add thise up u get $450 plus the 5 years you will have $950 i thonk that this is the right answer i dont really know
2x+1/2y=7
what is the answer
Answer for Y:
[tex]y = 2(7 - 2x)[/tex]
Answer for X:
[tex]x = \frac{7}{2} - \frac{y}{4} [/tex]
Answer:
y = -4x + 3.5
Step-by-step explanation:
2x + 1/2y = 7
-2x -2x
1/2y = -2x + 7
divide by 1/2
y = -4x + 3.5
WRITE THE EQUATION to Represent: Find x if the area of the rectangle
below is 124 square inches. WRITE THE EQUATION.

Answer:
4(6x+1)=124
Step-by-step explanation:
To find the area of a rectangle, you use this formula: area= length *width
so you input the length (6x+1) TIMES the width (4)
