Which table represents linear function?
Answer:
does not represent a linear function.
Step-by-step explanation:
For the function to be linear, the slope must be the same for every poknt along the function. If is not, then is not a linear function.
Let us now calculate the slope;
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
We shall take the first two points
[tex]m = \frac{4 - 2}{2 - 1} \\ m = \frac{2}{1} \\ m = 2[/tex]
Next we shall take the 2nd and 3rd points
[tex]m = \frac{8 - 4}{3 - 2} \\ m = \frac{4}{1} \\ m = 4[/tex]
The slope is not the same for these two different point, hence this table does not represent a linear function.

A rectangle prisms base is 8 feet long. It is 2 1/2 times taller than it is long and 1/2 wide as it is tall. What is the volume of the rectangular prism?
Answer:
1600 cubic feet
Step-by-step explanation:
8 x 2 1/2 = 8 x 2.5 = 20
20 divided by 1/2 = 10
8 x 10 x 20 = 1600
A jet travels 460 miles in 5 hours. At this rate, how far could the jet fly in 15 hours?
Answer:
1380 miles in 15 hours (92 mph).
Step-by-step explanation:
460/5 = 92.
92 mph.
92*15=1380
1380 miles in 15 hours
Answer:
1380 miles in 15 hours
Step-by-step explanation:
*Assuming the jet travel at a constant speed.
First, find the amount the jet flew in 1 hour. Divide 460 miles with 5 hours:
460/5 = 92
The jet travels 92 miles per hour.
Next, multiply 92 mph with 15 hours:
92 x 15 = 1380 miles
1380 miles in 15 hours is your answer.
4. Angie was given a gift card with a $75 balance. She only uses the gift card to purchase her daily cup of chai tea from her favorite café. A cup of tea is $2.85. The equation y = 75 - 2.85x represents the amount of money remaining on the gift card after x cups of tea. a. Identify and interpret the x- and y-intercepts. Round to the nearest tenth, if necessary. b. Predict how many cups of tea Angie has purchased when the gift card balance is about $35.
Answer:
Angie originally has $75 on her card.
She only uses the card for a daily cup of tea of $2.85
Then the equation:
y = $75 - $2.85*x
represents the balance on the card after x cps of tea.
a) The x-intercept is the pair (x, 0), meaning that y = 0, so this is the point at which the balance of the card is zero.
Here we need to solve:
0 = $75 - $2.85*x
$2.85*x = $75
x = $75/$2.85 = 26.3
Here we have a particular case because she can not buy 0.3 of a cup of tea, so the card will never reach a balance of $0.
The y-intercept is the pair (0, y) so we have x = 0, then: y = $75 - $2.85*0 = $75
This is the initial balance of the card.
b) Here we need to solve
y = $35 = $75 - $2.85*x
for x
$35 = $75 - $2.85*x
$35 + $2.85*x = $75
$2.85*x = $75 - $35 = $40
x = $40/$2.85 = 14.03
So after 14 cups of tea, the card's balance will be near $35.
Given the equation y = mx+q
Change the subject of the formula of
1.1.1 m
Answer:
m = [tex]\frac{y-q}{x}[/tex]
Step-by-step explanation:
Given
y = mx + q ( subtract q from both sides )
y - q = mx ( divide both sides by x )
[tex]\frac{y-q}{x}[/tex] = m
ASAP! what type of angles are <3 and <10
A. Consecutive interior angles
B. Alternate exterior angles
C. alternative interior angles
D. Corresponding angles
Answer:
∠3 and ∠10 are;
B. Alternate exterior angles
Step-by-step explanation:
From the given diagram, we have;
∠3 and ∠10 are angles on the same transversal
The location of ∠3 and ∠10 are on the outer (exterior) part of the two lines crossed by the transversal that forms ∠3 and ∠10 such that the two lines comes between the angles
∠3 and ∠10 are on the alternate sides of the transversal such that ∠3 is below the transversal and ∠10 is above the transversal
Therefore, ∠3 and ∠10 are alternate exterior angles.

The ratioof men to woman at a university is 6 to 5. How many woman students are there if there are 3600 men?
Answer:
There are 3000 woman students.
Step-by-step explanation:
Since the ratio is 6:5, so we have to reduce our number to 3000 from 3600 as 6x6=36 and then we can add the zeros.

Step-by-step explanation:
question:
i am not able to see the following. maybe you forgot to add it in? its okay since i have done that mistake before! but i wont be able to help with a problem i cant see :(
Help me, please, please!
x° = 118°
y° = 180° - (22° + 180° - x°)
y° = 180° - (22° + 180° - 118°)
y° = 180° - 22° - 180° + 118°
y° = 118° - 22°
y° = 98°
Helen needs 60 g of sugar to make 15 biscuits.
She also needs
three times as much flour as sugar
two times as much butter as sugar
Helen is going to make 60 biscuits.
a) Work out the amount of flour she needs.
Answer:
60 grams sugar for 15 biscuits.
3x60 grams of flour, so 180 grams for 15 biscuits.
60÷15= 4 batches.
4 batches with 180 grams each- 4 x 180= 720 grams of flour.
If time is four hours from now, the time left till midnight would be quarter that if it is one hour from now. What time is it now?
Answer:
The time now is 7 pm
Step-by-step explanation:
Suppose that now is the time T.
We know that:
"if time is four hours from now, the time left till midnight would be a quarter that if it is one hour from now".
Then:
if we define midnight as 12, and we assume that T is in the pm range.
Then the "time left till midnigth, assuming that the time is four hours from now" will be written as (12 - (T + 4))
With this in mind, we can write the problem as:
12 - (T + 4) = (1/4)*( 12 - (T + 1))
Now we can solve this for T.
12 - T - 4 = (1/4)*(12 - T - 1)
8 - T = (1/4)*(11 - T)
4*(8 - T) = 11 - T
32 - 4*T = 11 - T
32 - 11 = -T + 4*T
21 = 3*T
21/3 = T
7 = T
Then T = 7 pm
The time now is 7 pm

PyramidRectangular PrismCylinderConeTriangular Prism==============================================
Explanation:
The formula for the volume of a pyramid is (1/3)*B*h, where B is the area of the base. If we're dealing with a rectangular pyramid, like those found in Egypt, then the area of the base is B = length*width. The volume for a prism is found by multiplying length (L), width (W), and height (H). So V = LWH. Think of having a 2 by 3 rectangle of blocks. We would have 2*3 = 6 blocks in total. Then if we have 5 layers of these stacked then we have 2*3*5 = 6*5 = 30 blocks in total. This is one way to visualize how the volume formula works.To get the volume of a cylinder, we multiply the area of the base (pi*r^2) by the height (h). So that's where pi*r^2*h comes from.The volume of a cone is 1/3 that of a cylinder's volume. This is when the cone and cylinder have the same radius, and also the same height. It's not required that r = h.Since all of the other answer choices are used up, the only thing left is "triangular prism". It's strongly implied here that B is the area of the triangular base. Though the formula Bh applies to any prism and it doesn't have to be a triangular prism. Note how B = LW, so Bh is the same as LWH, meaning that a rectangular prism can use the Bh formula.9.

2- write 267000000 in standard form.
3- Maria, Carolina and Pedro receives $1600 from their grandfather in ratio 7:5:4. calculate share of each
Answer:
5.6715 * 10^26 kg
Step-by-step explanation:
Given that :
Mass of earth = 1/95 the mass of saturn
If Mass of earth = 5.97 x 10^24 kg
Let the mass of saturn = x
5.97 x 10^24 kg = 1/95 * x
5.97 x 10^24 kg = x / 95
x = 95 * 5.97 x 10^24 kg
x = 567.15 * 10^24
x = 5.6715 * 10^26 kg
Mass of saturn = 5.6715 * 10^26 kg

Ivana's furniture store buys a chair at a wholesale price of $320.00. If the markup rate at Ivana's store store is 40%, what is the total markup in dollars?
Answer: $128.00
Step-by-step explanation:
From the question, we are given the information that Ivana's furniture store buys a chair at a wholesale price of $320.00 and that the markup rate at Ivana's store store is 40%.
The total markup will then be:
= Markup rate × Price
= 40% × $320
= 0.4 × $320
= $128.00
three consecutive multiples of 2 is 36 then the multiples are
Answer:
9, 12, 15A multiple of 3 can be written 3n where n is a positive integer.
So 3 consecutive multiples of 3 can be written
3n,3n+3,3n+6
The sum of these is 36
3n+3n+3+3n+6=36
9n+9=36
Divide through by 9
n+1=4
n=3
If n=3 then 3n=9 and the three consecutive multiples of three are 9, 12 and 15 which do indeed total 36

While running a 2-sample z-test for two proportions, you find a test statistic of z=1.946. If the test is two-tailed and α=0.05, what decision will you make?
Answer:
Decision is to fail to reject the null hypothesis.
Step-by-step explanation:
Since our significance level is α = 0.05, but since it's a two tailed test for two proportions, in each tail, we will have 0.05/2 = 0.025.
Now, the rejection region will be the critical value at 1 - 0.025 = 0.975
From the z-table attached, the critical value at 0.975 is 1.96.
Thus, our decision rule will be;
If Z-score is less than -1.96, or greater than 1.96, we will reject the null hypothesis.
Now, we have a z-score of z = 1.946 in the question. This lies between -1.96 and 1.96.
Thus,we will fail to reject the null hypothesis
