Answer: 400 inches by 10 inches
Step-by-step explanation:
Length of the bridge = 4000feet
Width of the bridge = 100 feet
Since Sue decides that her scale model needs to be 1/10th the size of the real bridge.
If she uses a scale of inches to feet, the dimensions of her model will be:
Length = 4000 × 1/10 = 400 inches
Width = 100 × 1/10 = 10 inches.
Therefore, the dimensions are 400 inches by 10 inches

PLS HELP FIND ANGLE MEASUREMENTS
Answer:
From my observations, AOB looks like an isosceles triangle, so A=18 and B=18. Since a triangle must add up to 180. We do 180-18-18=144. O= 144. Then, triangle BOC looks like an isosceles triangle as well. So, we do 180-144= 36 so O = 36 and then we 180-36=144/2 because two sides have the same angles giving us 72 degrees for angles B and C = 72 and for O= 36
So,
x = 72
y = 36
9. Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch?*
Answer: Around 1000 students would buy a schoo lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a schoo lunch.
What are the 4 lowest numbers to average 80 percent . (Lowest possible and one of the numbers has to be 60)
Answer:
5,5,10, and 60
Step-by-step explanation:
Find the remaining numbers
80-60= 20
10 + 10 = 20
Break it up to get 4 numbers total
5 + 5 + 10 = 20
20 + 60 = 80

Answer: QPR=31
Step-by-step explanation: first you would combine 3x and 7x which equals 10x. Then you combine -95 and -38 which equals -133. then you set up an equation like 10x - 133 = 47. Add 133 to both sides. 10x = 180. Divide both sides by 10. X= 18. 18 times 7 equals 126. 126 - 95 equals 31
z+w−3=k
6z−10w=8
Answer:
if your looking for z it is 5/8k+2.375
Step-by-step explanation:
Answer:
Step-by-step explanation:
Please, include the instructions.
I'm assuming you want to solve this system of linear equations for z and w, assuming that k is an unknown constant.
Use the method of elimination by addition and subtraction. To eiiminate w, multiply all four terms of the first equation by 10, obtaining:
10 z + 10w - 30 = 10k
6z - 10 w = 80
Then 16z - 30 - 80 = 10k, or
16z -110 = 10k, Simplifying this, we get:
10(k + 11)
z = ---------------
16
Substituting this expression for z into the first equation, we get:
(10/16)(k + 11) + w - 3 = k. We must solve this for w:
-(10/16)(k + 11) + w - 3 = k), or
-(10/16)(k + 11) - w + 3 = -k
Then -(10/16)(k + 11) + 3 + k = w
and so the solution, in terms of the unknown constant k, is
10(k + 11)
( --------------, -(10/16)(k + 11) + 3 + k )

Sally built a rectangular prism using cubic units. What is the volume of the rectangular prism Sally built?
Answer:
64
Step-by-step explanation:
The volume of rectangular prisms is measured by l*w*h
And by counting the units of the length, width, and height are all 4 units long.
So take the numbers and plot them into the formula
4*4*4 = V
16 * 4 = V
64 = V
The prism is 64 cubic units.

is y=7x proportional
Answer: Yes. It is inversely proportional.
Step-by-step explanation:
In your question, the constant of proportionality already jump out at us which is to get y, we have to multiply x by 7. Therefore the constant of proportionality is y=7x.
If x= 2 what does y equal
Answer:6
Step-by-step explanation:
4.8(x)+1.2(y)=2.4
y would equal -6.
4.8(2)+1.2(y)=2.4
9.6 + 1.2y = 2.4 subtract 9.6 from both sides
1.2y = - 7.2 divide by 1.2 on both sides
y = -6

Monica uso 1,2 litros de leche para hacer 12 flanes iguales ¿cuantos litros de leche necesitaria para hacer 60 flanes? ¿cuantos flanes haria con 0,5 decalitros de leche?
Answer:
1. 6 L de leche.
2. 50 flanes.
Step-by-step explanation:
1. Determinación del volumen (en litros) necesario para realizar 60 natillas.
De la pregunta dada arriba,
Monica usó 1.2 L de leche para hacer 12 natillas iguales.
Por lo tanto, usará xL de leche para hacer 60 natillas, es decir
xL de leche = (1.2 × 60) / 12
xL de leche = 6
Por lo tanto, necesitará 6 L de leche para hacer 60 natillas.
2. Determinación del número de flanes (natillas) que se pueden producir utilizando 0,5 decalitros de leche.
Empezaremos por convertir 0,5 decalitros (deca) a litro (L).
Esto se puede obtener de la siguiente manera:
1 deca = 10 L
Por lo tanto,
0.5 deca = 0.5 deca × 10 L / 1 deca
0,5 deca = 5 L
Por tanto, 0,5 deca equivale a 5 L.
Finalmente, determinaremos el número de flanes (natillas) que se pueden obtener a partir de 0.5 deca (es decir, 5 L) como se muestra a continuación:
Monica usó 1.2 L de leche para hacer 12 natillas iguales.
Por lo tanto, usará 5 L de leche para producir = (5 × 12) /1.2 = 50 natillas
Por lo tanto, puede hacer 50 flanes (natillas) usando 0.5 deca (es decir, 5 L).

−5x + (−2) = −2x + 4
Answer:
x = -2
Step-by-step explanation:
Remove brackets
-5x - 2 = -2x + 4
Rearrange by collecting the like terms and putting them on either side
-5x + 2x = 4 + 2
Simplify
-3x = 6
Divide both sides by -3 to make x on its own
-3/-3x = 6/-3
x = -2
What is the answer for t?
4(t + 3) = 24
Answer:
3
Step-by-step explanation:
4(t +3)=24
4t +12 =24
4t =24 - 12
4t =12
t =12 :4
t =3
Answer:
t = 3
Step-by-step explanation:
Original Equation:
4(t + 3) = 24
Use distributive property
4 x t = 4t
4 x 3 = 12
Your equation:
4t + 12 = 24
Subtract 12 from both sides
4t = 12
Divide both sides by 4
t = 3
