Question seems incomplete but will be explained with assumptions
Answer and explanation:
If for example, a car travels 30 km per hour, then it would travel 60km in 2 hours and 90km in 3 hours and so on
We can apply the formula for distance as such:
Distance(d)= Speed(s) × time(t)
d=st
Where d is distance travelled say 60km
S is speed= 30km/hr
Time = 2 hrs
Also to calculate speed when distance and time is given, we can make speed the subject of the formula:
s=d/t
To calculate time when distance and speed are given, we can make time the subject of the formula:
t=d/s

consecues of chocoches should she use?
Question:
Consider a cookie recipe in which 1 1/2 cups of chocolate chips are needed to make 25 cookies. Lara wants to double the number of cookies. How many cups of chocolate chips should she use?
Answer:
[tex]Cups = 3[/tex]
Step-by-step explanation:
Given
[tex]Cups = 1\frac{1}{2}[/tex]
[tex]Cookies = 25[/tex]
Required
Number of cups when the cookies is doubled
When [tex]Cookies = 25[/tex], [tex]Cups = 1\frac{1}{2}[/tex]
So, when the number of cookies is doubled, the number of cups will also be doubled.
i.e.
[tex]Cookies = 25*2[/tex]
[tex]Cookies = 50[/tex]
and
[tex]Cups = 1\frac{1}{2} * 2[/tex]
Convert to improper fraction
[tex]Cups = \frac{3}{2} * 2[/tex]
[tex]Cups = \frac{3* 2}{2}[/tex]
[tex]Cups = \frac{6}{2}[/tex]
[tex]Cups = 3[/tex]
i.e. 3 cups are needed

An angle measures 130° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
An angle measures 130° more than the measure of its supplementary angle.
Therefore the required angle is (180°-130°)°=50°
50° is the right answer.The measure of the angle is A = 50° and the supplementary angles are given by 130° and 50°
What are Supplementary and Complementary Angles?Supplementary angles are two angles that have a sum of 180°.
Complementary angles are two angles that have a sum of 90°.
Given data ,
Let the first angle be represented as A
Now , the value of A is
Let the second angle be represented as B
And , the value of B is B = 130°
The angles A and B are supplementary
So , A + B = 180°
On simplifying , we get
The measure of A + 130° = 180°
Subtracting 130° on both sides , we get
The measure of angle A = 180° - 130°
The measure of angle A = 50°
Hence , the measure of angle is 50°

Answer:
c and d
Step-by-step explanation:
The equivalent ratios to 6 : 16 are, 3 : 8, 30/80 and 18 to 48.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, A ratio 6 : 16 = 3 : 8.
So, One equivalent ratio is 3 : 8.
Now, Going through options,
10×3 : 10×8.
= 30 : 80.
= 30/80.
6×3 : 6×8.

A popular soft drink is sold in 2-liter (2,000-milliliter) bottles. Because of variation in the filling process, bottles have a mean of 2,000 milliliters and a standard deviation of 20, normally distributed. a. If the process overfills the bottle by more than 50 milliliters, the overflow will cause a machine malfunction. What is the probability of this occurring
Answer:
0.0062 = 0.62% probability of this occurring
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 2000, \sigma = 20[/tex]
a. If the process overfills the bottle by more than 50 milliliters, the overflow will cause a machine malfunction. What is the probability of this occurring
Probability of filling the bottle with more than 2000 + 50 = 2050 milliliters, which is 1 subtracted by the pvalue of Z when X = 2050. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{2050 - 2000}{20}[/tex]
[tex]Z = 2.5[/tex]
[tex]Z = 2.5[/tex] has a pvalue of 0.9938
1 - 0.9938 = 0.0062
0.0062 = 0.62% probability of this occurring

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
The graph of a linear function is shown on the grid.
From the graph, the points are (-2.5, 0) and (0, 5) and the y-intercept is 5. The slope of the line is given as,
m = (5 - 0) / (0 + 2.5)
m = 5 / 2.5
m = 2
The slope of the equation is 2. Then the correct option is D.

Can some one help thanks
Answer:
y = 8
Step-by-step explanation:
First substitute x with 6 in the equation
2y + 1/3(6) = 18
Multiple 1/3 with 6, which is 2
2y + 2 = 18
Solve the equation by subtracting 2 from both sides
2y + 2 = 18
- 2 - 2
You get 2y = 16, so you divide 2 frm both sides
You get y = 8
