Answer:
89.14 Sq . meter
Step-by-step explanation:
Divide the figure into a semicircle with diameter 8 m and the remaining into a rectangle . The area of rectangle :
4 metres × 16 metres
= 64 sq. meter
Area of semicircle :
(pi×r^2)/2
= {(22/7)× (8/2)^2}/2
= (22×4×4)/(7×2)
= 176/7
= 25.14 sq. meter
Now , area of whole figure= (64+25.14)sq. meter
= 89.14 sq. meter

the base of a rectangular prism has an area of 1 over 8 ft2 and the height of the prism is 2 over 3 ft. what is the volume of the prism?
Answer: the volume is 1/12 ft³
Step-by-step explanation:
Multiply the area of the base times the height:
1/8 × 2/3 = 2/24 or 1/12
the ft² times ft becomes ft³
So the volume is 1/12 ft³

Hola alguien puede ayudarme a resolver estos ejercicios por favor Ejercicios de intervalos 1.- Escribe en todas las formas posibles los siguientes intervalos y semirrectas: a) { x / –2 ≤ x < 3} b) Números mayores que –1 c) (–[infinity], –5] d) Números mayores o iguales que –7 y menores que 19. e) Números mayores que 9 y menores que 5.
Answer:
Tenemos 3 formas de escribir cada intervalo, una es con solo texto, la otra es usando los símbolos { <, >, ≤, ≥ }, y la última es con intervalos, donde:
( se usa para " < x "
) se usa para " > x "
[ se usa para " ≤ x "
] se usa para " ≥ x "
a) -2 ≤ x ≤3
Esto se escribe como:
"números mayores o iguales que -2 y menores o iguales que 3"
y
[-2, 3]
b) Números mayores que –1
Las otras formas de escribir esto son:
-1 < x
y no tenemos limite mayor, entonces:
(-1, ∞)
con -∞ y ∞ siempre se usan los símbolos ( o )
c) (–[infinity], –5]
Las otras notaciones son:
"Un numero menor o igual que -5"
x ≤ -5
d) Números mayores o iguales que –7 y menores que 19
Las otras notaciones son:
-7 ≤ x < 19
[-7, 19)
e) Números mayores que 9 y menores que 5.
Las otras formas de escribir esto son:
5 < x < 9

4 Eric sketches a rectangle with a perimeter of
90 inches. The length of the rectangle is three
inches longer than the width. Which equation
can be used to determine x, the width of the
rectangle Eric sketched?
F 2x + 2x + 3 = 90
G 2(x + 3) = 90
H x(x + 3) = 90
J 2(x) + 2(x + 3) = 90
Answer:
2(x) + 2(x + 3) = 90
Step-by-step explanation:
Width: x inch.
Length: (x + 3) inch.
P = 2 [tex]w^{}[/tex] + 2 [tex]l^{}[/tex]
P = 2(x) + 2(x + 3) = 90
Daniel wants to know the volume of his cube. He notices that the cube 1/5 centimeters side lengths. What is the volume of the cube?
Answer:
1/125 cm^3
Step-by-step explanation:
Given data
Length of one side = 1/5cm
Required
The volume of the cube
We know that
V= l^3
substitute
V= (1/5)^3
V= 1/125cm^3
Hence the volume is 1/125 cm^3

The points (1,1) and (5,5) fall on a particular line. What is its equation in slope- intercept form
Answer:
y=x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-1)/(5-1)=4/4=1
slope is 1
y-y1=m(x-x1) where m=slope
y-1=1(x-1)
y-1=x-1
y=x-1+1
y=x
Answer:
y = x
Step-by-step explanation:
(1 , 1)
(5 , 5)
m = [tex]\frac{y}{x}[/tex]
m = [tex]\frac{4}{4}[/tex]
Tonya and Mario are asked to use a pan balance to find the mass of the same rock. Tonya finds the rock's mass to be 680 grams. Mario finds the rock's mass to be 672 grams. Which is the best explanation for the difference in their measurements?
A. Either Mario or Tonya measured the mass of the rock incorrectly on the pan balance.
B. The rock was cold when Tonya measured its mass and hot when Mario measured in mass.
C. The rock changed in size between the time Tonya measured it and the time Mario measured it.
D. The rock broke before Mario measured it. So the mass of the two pieces together was less than when Tonya measured it. PLEASEEEE HELPPP

In ΔRST, the measure of ∠T=90°, TS = 65, SR = 97, and RT = 72. What ratio represents the cotangent of ∠S?
Answer:
65/72
Step-by-step explanation:
Given that ∠T=90° then the triangle ΔRST is a right angled triangle. Considering ∠S, RT is the opposite side, TS is the adjacent side and RS is the hypotenuse side. Using the notation
SOH CAH TOA
Tan ∠S = 72/65
Hence the cotangent of ∠S which is the inverse of the tangent will be
= 65/72

Question 2
Evaluate the following function:
f(x) = 7x2 + 8x + 20 for f(2)
type the numerical value for your answer
Answer:
64
Step-by-step explanation:
We have the function f(x) 7x^2 + 8x + 20 and are asked to solve it.
Since we know that x equals 2. We can substitute 2 for every x in the expression.
7(2)^2 + 8(2) + 20
First do the exponent :
2^2
4
7(4) + 8(2) + 20
Multiply 7(4) and 8(2) :
7(4)
28
8(2)
16
28 + 16 + 20
64
Kiran's family took a road trip to Niagara Falls. Kiran slept through the last 62% of the trip. If the total length of the trip was 1000 miles, how many miles had they traveled when Kiran fell asleep?
Answer:
380 miles
Step-by-step explanation:
First, find 62% of 1,000:
1,000 • .62 = 620 miles
Next, subtract 620 from 1,000:
1,000 - 620 = 380 miles
The family had traveled 380 miles before Kiran fell asleep
