Choose either YES or NO to tell whether the expression is equivalent to 179 x 44
(179 x 40) + (179 x 4)
(100x4)+(70 x 4)+(9 x 4)
4,000 + 2,800 + 360 + 400 + 280 + 36
(100 x 44) + (70 x 44)+ (9 x 44)
179 (4 + 4)
Answer:
Step-by-step explanation:
(179 * 40) + (179 * 4) = 179 *(40 + 4) = 179 * 44
YES
(100 * 4) + 70*4 + 9*4 = 4 * ( 100 +70 + 9) = 4 * 179
No
4000 + 2800 + 360 + 280 +36 = 7876 = 179 *44
YES
(100 *44) + (70*44) + (9*44) = 44 * (100 + 70 +9) = 44 * 179
YES
179 *(4 +4) = 179 * 8
NO
what is f(0) for the function f(x) =2x+3
Answer:
3
Step-by-step explanation:
f(x) =2x+3
Let x=0
f(0) =2*0+3
Multiply
f(0) =0+3

A motorist drives at an average speed of 80 km/hr. How far does she travel in 3(1/2)
hours?
Answer: 280 km
Step-by-step explanation:
[tex]3\dfrac{1}{2} \: hours = 3.5 \: hours[/tex]
S = V × t
V = 80 km/h
t = 3.5 h
S = 80 × 3.5 = 280 km

What is an equation of the line that passes through the points (-5, -1) and (5, 3)?
a) Draw the graph of y = 4x - 1 on the grid. b) Use the graph to estimate the value of x when y = 1
Hello,
a) photo attached
b) When y = 1, x ≈ 0.5
Verification through calculation :
We have :
y = 4x - 1
⇔ 1 = 4x - 1
⇔ 4x = 2
⇔ x = 2/4 = 0.5
This is just !

which step in the construction of coping a lin segment ensures that the new line segment has the same length as the original line segment
Step-by-step explanation:
Now out of these points, i guess steps 5 and 6 are the main steps that ensure that the copied line segment is exactly the same as the original segment.
Here are the steps I think you probably will go through.
1. Draw a line that is longer than the segment but shorter than the width of the page.
1a. Make sure this line is at least 1/2 inch from the left hand side.
2. Use a compass to measure the length of the original segment. Never use a ruler. Rulers do not exist in pure geometry.
3. Measure out the distance on the line you just drew with the compass. One end is on the left hand edge and the other end (the pencil end) is marking the segment so it is the same length as the compass. You are done.
The key step either two or three.The steps to copy a line segment are given below:
1. Lets start with a line segment AB that we have to copy.
2. Now mark a point C. below or above AB, that will be one endpoint of the new line segment.
3. Now, put the compass tip on point A of the line segment AB.
4. Spread the compass up to point B, so as the compass width is equal to length of AB.
5. Without changing the compass width, now place the compass tip on the point C that you made in step 2.
6. Now, draw an arc roughly without changing the compass settings. Mark that point D. This will form the new line segment.
7. Draw a line from C to D.
Now out of these points, i guess steps 5 and 6 are the main steps that ensure that the copied line segment is exactly the same as the original segment.
In a school there are 1800 boys and 1200 girls. In an exam only 32 % of the boys passed and 50 % of the girls passed. Find the percentage of the total who did not pass.
Answer:
Step-by-step explanation:
The total number of students is 1800 + 1200 = 3000
The % of boys who did not pass is 100% - 32% = 68%
The number of boys who did not pass is 68/100 * 1800 = 1224
The % of the girls who did not pass is 100% - 50% = 50%
The number of girls who did not pass was 50/100 * 1200 = 600
The total number who did not pass was 1824
The % who did not pass was 1824/3000 * 100 = 60.8%

What type of transformation does shape A undergo to form shape B?
Answer:
Rotated 90° counterclockwise, then reflected across the y-axis
Step-by-step explanation:
By the definition of a ▱, AD∥BC and AB∥DC. Using, AD as a transversal, ∠A and ∠ are same-side interior angles, so they are . Using side as a transversal, ∠B and ∠C are same-side interior angles, so they are supplementary. Using AB as a transversal, ∠A and ∠B are same-side interior angles, so they are supplementary. Therefore, ∠A is congruent to ∠C because they are supplements of the same angle. Similarly, ∠B is congruent to ∠.

Write a quadratic equation that has the solutions: 4 and -7
Answer:
y = ( x-4)(x+7)
Step-by-step explanation:
When we know the zeros of the equation, we can write the equation in the form
y= a(x-z1) (x-z2) where a is a constant and z1 and z2 are the zeros (solutions)
y = a( x-4)(x--7)
y =a( x-4)(x+7)
Since its says write an equation, we can pick a and I will let a=1
y = ( x-4)(x+7)

Two large parallel metal plates carry opposite charges. They are separated by 85mm. The work done by the field is 6x10-3J and its field exerts on a particle with charge +8µC. Calculate the surface charge density on each plate.
Answer:
The surface charge density is [tex]7.8\times10^{-8} C/m^2[/tex].
Step-by-step explanation:
separation, d = 85 mm
Work, W = 6 x 10^-3 J
charge , Q = 8µC
The potential difference is given by
W = q V
[tex]V=\frac{6\times 10^{-3}}{8\times 10^{-6}}=750 V[/tex]
Let the charge on he capacitor is q.
[tex]q = CV\\\\q = \frac{\varepsilon oA}{d}\times V\\\\\frac{q}{A} = \frac{8.85\times 10^{-12}\times750}{0.085} =7.8\times10^{-8} C/m^2[/tex]

If sally completed 6 laps around a circular track with the dimensions shown below, how many meters will she have run? Use 3.14 for up and round your answer to the nearest tenth
Answer/Step-by-step explanation:
The diagram of the circular track is missing, and so also its dimensions.
However, let's assume the dimensions of the circular track given is diameter (d) = 20 meters or radius (r) = 10 meters.
Since it's a circular track, the circumference of the track would give us the number of meters she runs in 1 lap.
Circumference = πd
d = 20 m (we are assuming the diameter is 20 meters)
π = 3.14
Circumference of circular track = 3.14 × 20 = 62.8 m.
This means that 1 lap = 62.8 m that she would have to run.
Therefore,
6 laps would be = 6 × 62.8 = 376.8 m
Therefore, if she completes 6 laps around the circular track that has a diameter of 20 m, she will have to run about 376.8 m.

$500 is shared in ration 2:3 between two girls how much money did each girl receive workout please step by step
Answer:
100:350 simplified: [tex]\frac{2}{7}[/tex]
Step-by-step explanation
A ratio of 2:3 means that for every item of A, we can expect of item B. Therefore, our total group is 2+3=5.
Calculate expected number of item A:
[tex]\frac{2x500}{5}[/tex]
Expected number of item A: [tex]\frac{1000}{5}[/tex]
This fraction can be reduced by 5 giving you:
Expected number of item A: 200
Calculate expected number of item B:
[tex]\frac{3x500}{5}[/tex]
Expected number of item B: [tex]\frac{1500}{5}[/tex]
This fraction can be reduced by 5 giving you:
Expected number of item B: 300
A cube has square sides with area x2 +24x + 144. What expression represents the surface area of the cube?
Given:
A cube has square sides with area [tex]x^2+24x+144[/tex].
To find:
The expression that represents the surface area of the cube.
Solution:
It is given that,
The area of each side of cube = [tex]x^2+24x+144[/tex]
Number of sides of a cube = 6
Total surface area of the cube is the product of number of sides of the cube and the area of each side. So, the total surface area of the cube is
[tex]SA=6(x^2+24x+144)[/tex]
[tex]SA=6(x^2)+6(24x)+6(144)[/tex]
[tex]SA=6x^2+144x+864[/tex]
Therefore, the expression that represents the surface area of the cube is [tex]6x^2+144x+864[/tex].
Which is the graph of f(x) = (x + 3)(x - 2
Answer:
Step-by-step explanation:
f(x) = (x + 3)(x - 2) has two zeros: One stems from (x + 3) = 0 and is (-3, 0); the other stems from (x - 2) = 0 and is (2, 0).
The axis of symmetry is a vertical line located halfway between -3 and 2:
x = -1/2.
The graph opens up because the given (x + 3)(x - 2) has a positive leading coefficient (+1).
With this information we can eliminate the last two possible answers. Note that the x-intercepts of the first graph are -3 and 2, Thus, the first graph is the correct one.
