Answer:
22
Step-by-step explanation:
because if you divide 45 first it will be wrong so you must always first will the biggest number in your problem
Answer:22
Step-by-step explanation:
990/45
45 goes 2 times into 99 with 9 left over. Bring down the 0 and you have 90. 45 goes into 90 2 times evenly. So 22 is the answer,
52+42=7(8+6) yes or no?

Which steps show how to use the distributive property to evaluate 6.49?
O A. 6(49) = 6(50 – 1) = 6.50 +6.1 = 300 + 6 = 306
O B. 6(49) = 6(50 – 1) = 6 - 50 – 6.1 = 300 – 6 = 294
C. 6(49) = 6(50 – 1) = 6 - 50 – 50 · 1 = 300 – 50 = 250
O D. 6(49) = 6(50 – 1) = 6.50 – 1 = 300 – 1= 299
Answer:
Correct Choice: B. 294
Step-by-step explanation:
The distributive property allows modifying expressions in the form of a(b + c) into the form ab+bc.
If we wanted to express the product 6*49 as 6*(50-1), then applying the distributive property we have:
6*(50-1)=6*50-6*1
6*(50-1)=300-6
6*(50-1)=294
Correct Choice: B. 294
Answer:
Answer is B = 294

Answer:
54
Step-by-step explanation:
The sum of angles in this shape is equal to 360° one of the angle is given as 90°
so 90 + 5x = 360
5x = 270 divide both sides by 5
x = 54
You have $125.60 in quarters and
dimes. There is 956 coins
altogether. How many quarters do
you have?
Answer:
Quarters = q = 200
Dimes = d = 756
Step-by-step explanation:
Let
Dimes = d
Quarter = q
Value of each Dime = 0.10
Value of each Quarter = 0.25
d + q = 956 (1)
0.1d + 0.25q = $125.60 (2)
From (1)
d = 956 - q
Substitute d = 956 - q into (2)
0.1d + 0.25q = $125.60
0.1(956 - q) + 0.25q = $125.60
95.6 - 0.1q + 0.25q = $125.60
- 0.1q + 0.25q = 125.60 - 95.6
0.15q = 30
Divide both sides by 0.15
q = 30 / 0.15
= 200
q = 200
Substitute q = 200 into (1)
d + q = 956
d + 200 = 956
d = 956 - 200
= 756
d = 756
Therefore,
Quarters = q = 200
Dimes = d = 756

Answer:
x = 21
Step-by-step explanation:
By the corresponding angle theorem, we can find that the measure of the smaller angle made by transversal and m is 54°.
Using the vertical angle theorem, we can find that the missing angle is the triangle, the two known angles are 4x and 2x, is also 54°.
Since the sum of the interior angles of a triangle is always equal to 180°, we can make the equation:
2x + 4x + 54 = 180
Now we solve for x. Subtract 54 from both sides and combine like terms.
6x = 126
Divide both sides by 6.
x = 21
and now we have found the value of x. x = 21.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
x=21°
Step-by-step explanation:
Relations Between Angles
We need to recall two basic relations:
* Two angles opposite by crossing lines are always equal.
* The sum of angles in a triangle is 180°
We'll add some variables to the image, so x is easier found. Please check the image below.
The angles U and 54° are opposite and they must be equal, thus U=54°
Since m and n are parallel and they are crossed by a line, the angles V and U are equal, thus V=54°
Finally, The sum of the angles inside the triangle RST must be equal to 180°:
2x+4x+54=180
Joining like terms:
6x=180-54=126
Solving:
x=126/6
x=21°
Astrid is in charge of building a new fleet of ships. Each ship requires 40 tons of wood, and accommodates
300 sailors. She receives a delivery of 4 tons of wood each day. The deliveries can continue for 100 days at
most, afterwards the weather is too bad to allow them. Overall, she wants to build enough ships to
accommodate at least 2100 sailors.
How much wood does Astrid need to accommodate 2100 sailors?
Answer:
it requires 280 ton of wood
Step-by-step explanation:
one ship can accommodate 300 sailors so for 2100 sailors you need
2100/300
7 ships
and as I ship require 40 tons of wood then 7*40
280 tons
then
he can get 4 ton of wood per day
then
280/4
70 days
therefore he needs wood for 70 days to accommodate 2100 sailors

Answer:
It is B
Step-by-step explanation:
Plug each value possible into the equation
(48+x) / 31 = x/15
If both sides are equal when you plug x in, it's correct
If they aren't equal, it is wrong.
How did I get this equation?
Lets use proportions to solve.
Since they are similar, (the two triangles are similar, meaning that they have the same ratio of the y and x axis values) you can use proportions meaning you make it so x over 15 is equal to the total length by the total bottom length.
If you plug 45 in as x, you get (48 + 45) divided by 31 is equal to 45/15
If you simplify the equation, you get 93 divided by 31 is equal to 3, of which 93 divided by 31 is 3
I think you know that 3=3
so it is correct.
Jasmine is in charge purchasing tubes of silicone sealant, used for finishing restroom facilities. She finds that she is able to purchase silicone sealant in cone tubes. She knows that a jumbo cone of sealant has a top diameter of 12 inches and a height of 14 inches, and a regular cone of sealant has a top diameter of 6 inches and a height of 7 inches. Jasmine believes that with her order of sealant, that she can get the same amount of silicone sealant from two regular cones as from one jumbo cone.
The question attached is:
Is Jasmine correct about the silicone sealant cones?
If you think Jasmine is correct to explain, why.
Answer:
Jasmine is correct about the silicone sealant cones
Step-by-step explanation:
Given that:
Jumbo cone of sealant has a top diameter of 12 inches and a height of 14 inches, Suppose Jasmine orders or demands for two regular cones of regular sealant, definitely, that will be equal to the Jumbo cone of sealant.
This is because the top diameter when put together in a Jumbo cone will give an actual result as a Jumbo cone, for as much as 6 × 2 = 12 inches (top diameter) and 7 × 2 = 14 inches (height).

Bobby charges $10. per lawn he mows, and an additional $5. per hour.
a) Find the independent and the dependent variables.
b) Write a linear function that models the wage of Bobby per lawn.
c) If Bobby work for 3.5 hours on a lawn, how much does he earn?
Answer:
a) independent = hours
dependent = wages
b ) W = 10 + 5h
c)27.50
Step-by-step explanation:
The independent variable is the one that you change which is the number of hours that it takes
The dependent variable is the variable that changes based on the independent variable. The wages depends on the hour worked so the wages are the independent variable
The wages equal the fixed cost plus the hourly rate times the number of hours where W is the wages and h is the number of hours
W = 10 + 5h
W = 10 + 5( 3.5)
= 10 + 17.5
= 27.5

180+8x=160+6x help me find x
Answer:
x = -10
Step-by-step explanation:
Step 1: Write equation
180 + 8x = 160 + 6x
Step 2: Solve for x
Subtract 6x on both sides: 180 + 2x = 160Subtract 180 on both sides: 2x = -20Divide both sides by 2: x = -10Step 3: Check
Plug in x to verify it's a solution.
180 + 8(-10) = 160 + 6(-10)
180 - 80 = 160 - 60

Write the equation of a line that is perpendicular to the line that passes through (4,−3)and (−7,8).
Line perpendicular to a given line is = 1/m
To find m, use m =y2-y1/x2-x1 formula
m = (8-(-3))/(-7-4)
m = 11/-11,
m = -1
Use y= mx+c to find equation of line
Plug in a pair of values,
-3= -1(4)+ c
c= 1
Thus, equation is:
y = -x+1
Equation of line perpendicular to this line is:
y= x+1

SITUACIÓN 2: Confecciones
Margarita tiene un taller de confecciones y está elaborando mascarillas de tela. Esta semana sus pedidos de mascarillas han disminuido a la mitad por lo que deberá comprar 50 % menos de tela para confeccionar mascarillas. ¿Cuál de las siguientes representaciones muestra de mejor manera las cantidades de tela que necesitará Margarita cada semana? Argumenta tu respuesta.
Answer:
La representación que muestra de mejor manera las cantidades de tela que necesitará Margarita cada semana es:
Representación A.Step-by-step explanation:
Como puedes identificar del enunciado, es ÉSTA semana en la cual los pedidos de mascarillas han disminuído a la mitad (o 50%, que sería lo mismo), por lo tanto, es en esta semana cuando el pedido de tela va a disminuir a la mitad, además debes identificar que el enunciado hace énfasis en que sus pedidos han disminuído, por lo cual puedes deducir que regularmente sus pedidos de mascarillas son el doble de lo solicitado en esta semanal, considerándose lo ocurrido en ésta semana como una anomalía, teniendo en cuenta esto, la próxima semana seguramente los pedidos volverán a la normalidad, necesitándose el doble de tela que en esta semana.
En la representación A puedes ver que se representa la cantidad de tela de ésta semana con un rectángulo, lo cual podría considerarse una unidad, y ya que sabemos que la próxima semana las confecciones de mascarillas seguramente regresarán a la normalidad, es lógico que la cantidad de tela requerida será el doble, así pues, si en esta semana se requirió una unidad de tela, en la proxima semana se requerirán dos, por lo cual la única opción que cumple con estos parámetros es la A.
