Answer:
c = 2, d = - 3
Step-by-step explanation:
Expand and simplify the left side then compare the coefficients of like terms on both sides.
5(2x + 1) + c(x + d) ← distribute parenthesis
10x + 5 + cx + cd
= x(10 + c) + 5 + cd
Compare like terms on both sides, that is
10 + c = 12 ( subtract 10 from both sides )
c = 2
Then
5 + cd = 5 + 2d and
5 + 2d = - 1 ( subtract 5 from both sides )
2d = - 6 ( divide both sides by 2 )
d = - 3

A serving size of Oreo cookies is 3 cookies, which is 20% of a box of cookies. How many cookies come in a box?
Answer:
no one eats oreos fatty
Step-by-step explanation:
The number of cookies that came inside the box is 15.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A serving size of Oreo cookies is 3 cookies, which is 20% of a box of cookies.
Let 'x' be the number of cookies the box has.
Therefore 20% of 'x' is 3 which is,
(20/100)×x = 3.
0.2x = 3.
x = 3/0.2.
x = 15.
So, There are 25 cookies in the box.

Determine whether the measures 2, √8, and √12 can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse,
or right. Justify your answer.
Answer:
C
Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = [tex]\sqrt{12}[/tex] and ([tex]\sqrt{12}[/tex] )² = 12
2² + ([tex]\sqrt{8}[/tex] )² = 4 + 8 = 12
Thus the triangle is right → C
Answer:
C.
Step-by-step explanation:
Squaring the numbers we get 2^2 = 4, 8 and 12.
Lets look at the relation between 4 8 and 12:-
12 = 4 + 8
- so it obeys the Pythagoras theorem.
It is a right triangle and the answer is C.

Jesse is making fruit salad. She purchased 5 & 1/3 ounces of 6 different fruits. How many ounces of fruit did she purchase?
Answer:
32 ounces of fruits
Step-by-step explanation:
Given that :
Number of distinct fruits purcahed = 6
Number of ounces of each fruit = 5 1/3
The total ounces of fruits purchased :
(Number of distinct fruits purchased * Number of ounces of each fruit)
6 * 5 1/3 = 6 * 16/3
6 * 16/3 = (16 * 6) / 3 = 96 /3 = 32 ounces of fruits.
Thomas has 12 more marbles than twice the number of marbles Andrew has. Andrew has x marbles. Which expression represents how many marbles Thomas has?
Answer:
2x + 12
Step-by-step explanation:
Let
x = number of marbles Andrew has
Number of marbles Thomas has = 2x + 12
The expression which represents number of marbles Thomas has = 2x + 12
If Andrew has 2 marbles, that is, x = 2
Then, 2x + 12 = 2(2) + 12
= 4 + 12 = 16
Thomas = 16 marbles
Does anyone know the answer?
Answer:
d = 9
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 3
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (d, 21)
m = [tex]\frac{21-6}{d-4}[/tex] , that is
[tex]\frac{15}{d-4}[/tex] = 3 ← multiply both sides by d - 4
15 = 3(d - 4)
15 = 3d - 12 ( add 12 to both sides )
27 = 3d ( divide both sides by 3 )
9 = d , that is
d = 9

The speed of sound (shockwave) in an explosion is 100mph. How many seconds does the shockwave reach 2km away?
Answer:
t = 44.73 s
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 100 mph = 44.704 m/s
We need to find the time taken by the shockwave to reach 2 km i.e. 2000 m
We know that,
Speed = distance/time
So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{2000}{44.704}\\\\t=44.73\ s[/tex]
So, it will take 44.73 seconds to reach 2 km.
Geometry - Law of Sines question #17. Please help, I am stuck.
By the law of sines, m∠EFG is such that
sin(m∠EFG) / (8 in.) = sin(m∠G) / (7.5 in)
so you need to find m∠G.
The interior angles to any triangle sum to 180°, so
m∠DEG = m∠D + m∠G + 43°
m∠DEG + m∠D + m∠G = 2 (m∠D + m∠G) + 43°
180° = 2 (m∠D + m∠G) + 43°
137° = 2 (m∠D + m∠G)
68.5° = m∠D + m∠G
But ∆DEG is isosceles, so m∠D = m∠G, which means
68.5° = 2 m∠G
34.25° = m∠G
Then
sin(m∠EFG) = (8 in.) sin(34.25°) / (7.5 in)
m∠EFG ≈ sin⁻¹(0.600325) ≈ 36.8932°
Work out the point of intersection of the lines
2x + 3y = 11 and 2y = 13 – 3x
Answer:
x = 3.4
y = 1.4
Step-by-step explanation:
2x + 3y = 11
2y = 13 – 3x, then y = (13 - 3x)/2
substitute for y:
2x + 3((13 - 3x)/2) = 11
reduce:
2x + (39 - 9x)/2 = 11
reduce:
2x + 19.5 - 4.5x = 11
subtract 19.5 from both sides of the equation and combine for x:
-2.5x = -8.5
divide both sides by -2.5:
x = 3.4
y = (13 - 3(3.4))/2 = (13 - 10.2)2 = 1.4

En una muestra de 50 restaurantes de comida rápida, la venta media fue de $3.000, y la desviación estándar, $200. El intervalo de confianza del 95% es
Respuesta:
(2945.411; 3054.589)
Explicación paso a paso:
Dado ;
Tamaño de la muestra, n = 50
Media, xbar = 3000
Desviación estándar, s = 200
Nivel de confianza, Zcrítico al 95% = 1,96
El intervalo de confianza se define como:
Xbar ± margen de error
Margen de error = Zcrítico * s / sqrt (n)
Margen de error = 1,96 * 200 / sqrt (50)
Margen de error = 54.589
Límite inferior = (3000 - 54.589) = 2945.411
Límite superior = (3000 + 54.589) = 3054.589
(2945.411; 3054.589)

A rectangle has an area of 1,280.64 square miles and a base of 36.8 miles. What is the height?
Answer:
34.8 miles
Step-by-step explanation:
First, we know that Area = Length * Width. Let's plug in those values.
1,280.64 = x * 36.8 (I put the variable "x" there since we don't know what it is)
Now, solve for x (we want to have x by itself, so divide both sides by 36.8)
34.8 = x
Now that we know that the width of it is 34.8 miles, let's check our work.
34.8 * 36.8 = 1,260.64
This equation IS true, so:
The width of the rectangle is 34.8 miles. Hope this helps!
Anne wants to fill 12 hanging baskets with compost. Each hanging basket is a hemisphere of diameter 40 cm.
Anne has 4 bags of compost. There are 50 litres of compost In each bag. Has Anne got enough compost to fill the 12 hanging baskets?
Answer:
no
Step-by-step explanation:
Steps to answering this question
determine the volume of the 12 basketvolume of a hemisphere = (2/3)πr^3
n = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 40/2 = 20 cm
volume of one hemisphere = (2/3) x (22/7) x (20^3) = 16,761.90 cm^3
volume of the 12 baskets = 16,761.90 cm^3 x 12 = 201,142.86 cm^
2. convert the litres of compost to cm and multiply by the total bags of compost
1 litre = 1000cm
1 bag of compost = 50 x 1000 = 50,000
4 bags of compost = 50,000 x 4 = 200,000 cm
3. compare which figure is higher. the figure gotten in step 1 or 2
201,142.86 cm^3 is greater than 200,000
there is no enough compost

The area of a right triangle is 3gh. Find the height if the base is 3gh.
Area of a triangle: A = 1/2bh
Answer: height is 2
Step-by-step explanation:
A = 1/2bh
A = 3; b (base) = 3. Substitute these values in the formula and solve.
3 = 1/2*3*h = 3/2 h
h = 3 * (2/3) = 2
Answer:
Height = 2
Step-by-Step Explanation:
So, I'm not sure if "gh" is a measurement. But I'm thinking it should be solved like this.
Area = 3gh
Base = 3gh
Height = ?
Plug & Chug
3gh = 1/2 (3gh)(h)
2/1 · 3gh = 1/2 (3gh)(h) · 2/1
[tex]\frac{(2)(3gh)}{(3gh)\\}[/tex] = [tex]\frac{(3gh)(h)}{(3gh)}[/tex]
h = [tex]\frac{(2)(3gh)}{(3gh)}[/tex]
h = 2
