mrs perry shares out 30 biscuits between gemma and zak in the ration 1:4 how many biscuits does each child get
Gemma gets 6 biscuits, and Zak gets 24 biscuits when Mrs. Perry shares out 30 biscuits between them in the ratio 1:4.
To solve this problem, we need to divide the 30 biscuits according to the ratio 1:4 between Gemma and Zak.
Calculate the total parts in the ratio.
Total parts = 1 (from Gemma) + 4 (from Zak) = 5 parts
Find out how many parts each child gets.
For Gemma:
Gemma's share = (1 part ÷ 5 parts) × 30 biscuits
= (1/5) × 30
= 6 biscuits
For Zak:
Zak's share = (4 parts ÷ 5 parts) × 30 biscuits
= (4/5) × 30
= 24 biscuits
Verify the result.
Gemma gets 6 biscuits, and Zak gets 24 biscuits.
6 + 24 = 30 biscuits (which is the total), so the division is correct.
Thus, Gemma gets 6 biscuits, and Zak gets 24 biscuits when Mrs. Perry shares out 30 biscuits between them in the ratio 1:4.

Marcel is designing a circular necklace that will consist of 4 sections, each with a different color of plastic. Determine how he needs to cut the plastic by finding the measures of the angles.

measure of angle 1 is 83 and measure of angle 2 is 97
Step-by-step explanation:
edg
Marcel needs to cut the plastic to create four equal angles of 90 degrees each for his circular necklace since a circle has a total of 360 degrees.
Explanation:The student is being asked to calculate the measures of the angles in a circular necklace that is divided into four equal sections. Since a circle has 360 degrees, and the necklace is divided into four sections, each section must be an equal fraction of the total degrees in a circle. To find the measure of each angle, we divide the total degrees in a circle (360) by the number of sections (4).
Step-by-step calculation:
Identify the total degrees in a circle: 360 degrees. Divide this number by the number of sections: 360 ÷ 4. Calculate the result: each section has an angle of 90 degrees.
Therefore, Marcel needs to cut each angle at 90 degrees to create four sections of the circular necklace.

The equation of line q is 5y - 4x = 10. Write the standard form of the equation of the line that fits the following description: parallel to q and passes through the point at (-15, 8)
Answer:
y = [tex](\frac{4}{5})[/tex]x + 20
Step-by-step explanation:
The equation of line q is 5y - 4x = 10
5y = 4x + 10
y = [tex]\frac{4}{5}x+2[/tex]
If a line is parallel to this line the slope of the line will be the same as the given line = [tex](\frac{4}{5})[/tex]
Let the parallel line is y = mx + c
where m = slope
and c = y-intercept
equation will be y = [tex]\frac{4}{5}x+c[/tex]
This line passes through (-15, 8)
so 8 = (-15) [tex](\frac{4}{5})[/tex] + c
8 = -12 + c
c = 12 + 8
c = 20
Now the equation of the parallel line will be y = [tex](\frac{4}{5})[/tex]x + 20

Under which condition does a country with a small GDP have a large per capita income?
Answer:
Small population
Step-by-step explanation:
GDP is defined as the Gross domestic product of a country. It is the amount of money made in the country at a specific period of time. It measures the economic state and progress of the country.
Per capital income is the average income citizens earn in a country.
However a country with a small GDP will have a large per capital income only if the population size of the country is small. This small population size will make it possible for less competition and more money going round for the citizens.

2.05 MC) Triangles ABC and DEF. Coordinates for A are 0, 2, for B 2, 4, and for C 1, negative 2. Given: ΔABC ≅ ΔEFD What is the length of Segment line FE rounded to the nearest tenth? (4 points) 2.8 3.4 4.1 6.1
Answer:
2.8
Step-by-step explanation:
From the congruence statement, we see that AB corresponds with EF; this means they will be congruent.
To find the measure of FE, we will find the distance between points A and B using the distance formula:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Using our coordinates for A and B, we have
[tex]A(0,2)\text{and }B(2, 4)\\\\d=\sqrt{(4-2)^2+(2-0)^2}=\sqrt{2^2+2^2}\\\\=\sqrt{4+4}=\sqrt{8}=2.828427\approx 2.8[/tex]

7/16
5/8
1 3/16
13/16 - 3/8
convert 3/8 to 16ths
3/8 = 6/16
13/16 - 6/16 =
13/6 =7
7/16 is the answer
Answer:
The correct option is 1.
Step-by-step explanation:
The given expression is
[tex]\frac{13}{16}-\frac{3}{8}[/tex]
We need to perform the indicated operation.
Make denominator common.
[tex]\frac{13}{16}-\frac{3\times 2}{8\times 2}[/tex]
[tex]\frac{13}{16}-\frac{6}{16}[/tex]
It can be written as
[tex]\frac{13-6}{16}[/tex]
[tex]\frac{7}{16}[/tex]
The value of given expression is [tex]\frac{7}{16}[/tex].
Therefore the correct option is 1.

If EF =9x+17 , FG = 35 , and EG=196 , find the value of x
The required simplified value fo x is 16 in the expression of the line segment.
Given that,
If EF =9x+17 , FG = 35 , and EG=196 , find the value of x is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here
EG = 196
EF + FG = 196
9x + 17 + 35 = 196
9x + 52 = 196
9x = 196 - 52
9x = 144
x = 144/ 9
x = 16
Thus, the required simplified value fo x is 16 in the expression of the line segment.

You ride your bike to school. As you approach an intersection, you decrease your speed by 1.5 miles per hour per second. Select an inequality that represents the time tt (in seconds) until your speed decreases by more than 10.5 miles per hour. Then solve the inequality.
Answer:
The time elapsed is greater than 7 seconds
Step-by-step explanation:
From definition
acceleration = change in speed/time elapsed
or:
a = Δv/t
Rearranging:
a*t = Δv
If your speed decreases by more than 10.5 miles per hour, then:
Δv > 10.5
Replacing with the previous equation and solving for t:
a*t > 10.5
t > 10.5/1.5
t > 7 s
How do you write a piecewise function
To write a piecewise function, you need to define different equations for different intervals of the independent variable.
Explanation:To write a piecewise function, you need to define different equations for different intervals of the independent variable. Each equation represents a different part or piece of the function. Here's an example:
f(x) =
2x + 1, if x ≤ 0x^2, if 0 < x ≤ 54 - x, if x > 5In this function, the equation 2x + 1 is used for values of x that are less than or equal to 0, the equation x^2 is used for values of x between 0 and 5 (inclusive), and the equation 4 - x is used for values of x greater than 5.

A line blank has endpoints
Answer: A line never has endpoints .
Step-by-step explanation:
In geometry , a line is a straight one-dimensional undefined figure which extends infinitely in both directions.
Thus , a line contains no endpoints because it is extending infinitely in both the directions.
If a line has one end point then we call it a ray and if it has both endpoints then we call it line-segment.
Therefore , the complete sentence will be : A line never has endpoints
