Answer:
w = r1r2t is the correct answer which would be the letter C. This is the one that is not algebraically correct.
Step-by-step explanation:
When solving this equation for t the step w= r₁r₂t would not be algebraically correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The following are the basic principles and steps to summarize any linear algebra statement:
Erase all packaging symbols, such as parenthesis and parenthesis, by dividing factors.
Using the exponent rule, grouping can be rule out if the words contain decimals.
To merge words, omit or add similar pictures.
It is given that,
The work accomplished by two people working on the same task for the same amount of time but at different rates is given by the equation,
w=r₁t+r₂t
Taking t common,
w=(r₁+r₂)t
Rearrange the equation as
t=w / (r₁+r₂)
Thus, when solving this equation for t the step w= r₁r₂t would not be algebraically correct.

Kyra was building a bed for her dollhouse. She used her bed, which is 4 feet × 5 feet, as a guide. She scaled down the dimensions of her bed by a factor 1/5. What are the dimensions of the model bed she built?
A,) 0.8 ft × 0.1 ft
B.) 0.4 ft × 0.5 ft
C.) 0.8 ft × 1 ft
D.) 0.04 ft × 0.05 ft
Answer: C. 0.8 ft x 1 ft
Step-by-step explanation:
The scale factor of 1/5 means you multiply
the dimensions by 1/5
4 * 1/5 = 0.8
5 * 1/5 = 1
Answer:
C. 0.8 ft x 1 ft

Angela is following this recipe to make biscuits.
Angela uses 1.8 l of syrup.
How much margarine is needed in kg?
Recipe: Makes 10 biscuits
150 g margarine
180 g sugar
225 ml syrup
225 g oats
40 g sultanas
Asapppp
Answer : The amount of margarine needed is 1 kg.
Step-by-step explanation :
First we have to convert volume of syrup from mL to L.
Conversion used:
1 L = 1000 mL
or, 1 mL = 0.001 L
So, 225 mL = 0.225 L
Now we have to calculate the amount of margarine needed.
As, 0.225 L of syrup needed 150 g of margarine
So, 1.8 L of syrup needed [tex]\frac{1.5L}{0.225L}\times 150 g=1000g[/tex] of margarine
Amount of margarine needed = 1000 g = 1 kg (1 kg = 1000 g)
Therefore, the amount of margarine needed is 1 kg.

It’s just 22-24
Answer:
1) 5.9
2) 8.1
3) 54
Step-by-step explanation:
A is opposite, so we have sine 36=a/10
sine 36(10)=a
a=5.9
B is adjacent, so we have cosine 36=b/10
cosine 36(20)=b
b=8.1
Angles of a triangle add to 180
we have a angle of 36 and a right angle which is 90
36+90=126
180-126=54

Which of the following choices is the x intercept of the equation 2y-x=-6
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
Given
[tex]2y-x=-6[/tex]
Required
Determine the x intercept
To get the value of x intercept; we simply substitute 0 for y;
i.e. y = 0
[tex]2y-x=-6[/tex] becomes
[tex]2(0)-x=-6[/tex]
[tex]0-x=-6[/tex]
[tex]-x=-6[/tex]
Multiply both sides by -1
[tex]-1 * -x=-6 * -1[/tex]
[tex]x=-6 * -1[/tex]
[tex]x = 6[/tex]
Hence, the x intercept is 6

2p+8=20-p what is the value of p??
Answer:
4
Step-by-step explanation:
3p+8=20
3p=12
p=4
Answer:p=4
Step-by-step explanation:
2p+8=-p+20
Step 2: Add p to both sides.
2p+8+p=-p+20+p
3p+8=20
Step 3: Subtract 8 from both sides.
3p+8-8=20-8
3p=12
Step 4: Divide both sides by 3.
3p/3=12/3
p=4

Since 64 is a perfect cube ³√64 = 4
and the exponents 27 and 125 are also perfect cubes ³√27= 3 and ³√ 125 = 5 respectively.
Answer:
D.
Step-by-step explanation:
64 = 4³
x^(27) = (x^3)^3
y^(125) = y^(5*5*5) =(y^5)^3
D. 64x^(27)y^(125) = (4x^3 y^5)^3

Answer :
(i) The size of angle x is 58⁰.
(ii) The size of angle y is 70⁰.
Step-by-step explanation :
From the given figure we conclude that:
∠EFB = ∠FGD = x⁰ (corresponding angles are equal)
∠FGD = ∠CGH (vertically opposite angles are equal)
x⁰ = 58⁰
∠FGD = ∠AFG = 58⁰ (alternate angles are equal)
Now we have to calculate the value of 'y'.
As we know that the sum of interior angle of a triangle is equal to 180⁰.
In ΔAGF,
∠GAF + ∠AFG + ∠FGA = 180⁰
52⁰ + 58⁰ + y = 180⁰
110⁰ + y = 180⁰
y = 180⁰ - 110⁰
y = 70⁰
Therefore, the value of size of angle x and angle y is 58⁰ and 70⁰ respectively.
Celia uses 30% of the money in her savings account to buy a present for her grandmother on her 80th birthday. The present costs $45. The bar model represents this situation. What is the value of each section of the bar, and how much money did Celia originally have in her savings account? A bar model divided into ten equal parts. The first 3 parts from the left each say fifteen. These 3 parts altogether are labeled forty-five. A number line appears above the bar model. It has eleven tick marks that divide it into ten parts, with each part the same width as a part in the bar model. The tick marks go from zero percent to one hundred percent in increments of ten. A Each section represents $13.50. Celia originally had $135 in her account. B Each section represents $15. Celia originally had $150 in her account. C Each section represents $30. Celia originally had $300 in her account. D Each section represents $45. Celia originally had $450 in her account.
Answer:
its each section represents $30. celia originally had $150 in her account
Step-by-step explanation:
there are 3 sections on the bar there are 45 she had 10 sections which is why the answer is this

Answer:
c: 5 x 3/5
Step-by-step explanation:
so the is 15 blocks shaded on the 25 grid
so i would work out each fraction answer and find which one makes 15/25
5 x 5/3 = 25/25
3/5 + 3/5 + 3/5 + 3/5 + 3/5 + 3/5 = 21/5
5 x 3/5 = 15/25
hope this helps :)
if the answer is wrong plz comment and i will fix thanks :)
Answer:
c) 5x3/5
Step-by-step explanation:
Look at one of the bars only. We see that 3 blocks out of 5 are colored in.
So that means the fraction is 3/5. But since there are 5 bars, we must multiply the fraction by 5.
Therefore, the answer is c) 5x3/5
hope this helped:)

HELP ITS ABOUT POINTS AND EQUATIONS AND WHAT THE PERSON FAILED IN DOING EXPLANATION NEEDED PLEASE
Answer:
see below
Step-by-step explanation:
First find the slope
m= ( y2-y1)/(x2-x1)
= (-5- -7.5)/ ( 2 - -3)
= (-5+7.5) / ( 2+3)
= 2.5 /5
=1/2
Then using the slope intercept equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 1/2x+b
Using a point from above
-5 = 1/2(2) +b
-5 =1+b
Subtract 1 from each side
-6 = b
We have the y intercept
y = 1/2x-6
Tahlia forget to find the y intercept for the equation
Answer:
y = 0.5x - 6
Step-by-step explanation:
(-3. -7.5) ; (2 , -5)
[tex]Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-5-[-7.5]}{2-[-3]}\\\\=\frac{-5+7.5}{2+3}\\\\=\frac{2.5}{5}\\\\=0.5[/tex]
m = 0.5 ; (2, -5)
equation of line : y-y1 = m(x-x1}
y -[-5]=0.5(x - 2)
y + 5 = 0.5x - 0.5*2
y + 5 = 0.5x - 1
y = 0.5x - 1 -5
y = 0.5x - 6

Answer: Yes, there is a relationship. As time increases, texting speed decreases.
Step-by-step explanation:
that is for the people looking for the correct answer.
The correct option is B, Yes, there is a relationship. As time increases, texting speed decreases.
What is a scatter plot?A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed.
Although the points plotted on the graph are completely scattered. There exists a basic relationship between the points, as time increases, texting speed decreases, moving from the left side of the graph to the right side of the graph. Hence, the correct option is B, Yes, there is a relationship. As time increases, texting speed decreases.

Pregunta completa:
Al llegar al hotel nos an dado un mapa con los lugares de la ciudad nos dijieron que 5 cm del mapa que representaban 600 metros de la realidad hoy queremos ir a un par que que se encuentra a 8 cm del hotel en el mapa. ¿A qué distancia del hotel está la pareja?
Respuesta: 960m
Explicación paso a paso:
Dado que:
5 cm en el mapa equivale a 600 m en tierra Por lo tanto,
8 cm en el mapa será equivalente a:
5 cm en el mapa - - - - - -> 600 m en el suelo 8cm - - - - - - -> y metros en el suelo
Usando la multiplicación cruzada
y × 5 = 8 × 600
5y = 4800 Luego,
y = 4800/5
y = 960m
Por lo tanto, 8 cm en el mapa serán 960 m en realidad.
