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.
Answer:
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.
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

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

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]
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
Which of the following is a true statement a.5/6>10/12
B.6/9=1./3
C.13/15>4/5
D.1/4>1/3
The true statements among the given statement by converting them as like fractions is equal to option c. 13/15 > 4/5.
To compare fractions, it's helpful to have them with the same denominator.
Let's convert each fraction to a common denominator, and then we can compare them:
a. 5/6 > 10/12
Common denominator for 6 and 12 is 12:
5/6 = 10/12
So, a is not true.
b. 6/9 = 1/3
Both fractions are simplified and convert to have same denominator (9),
6/9 and 3/9
6/9 > 3/9
so b is not true.
c. 13/15 > 4/5
Both fractions are simplified and convert to have the same denominator (15),
4/5 = 12/15
13/15 > 12/15
and we can see that 13/15 is greater than 4/5, so c is true.
d. 1/4 > 1/3
To compare these fractions, we need a common denominator, which is 12:
1/4 = 3/12
1/3 = 4/12
Now we can see that 1/3 is greater than 1/4, so d is not true.
Therefore, the true statements is option c. 13/15 > 4/5.

Which lines are parallel in the square pyramid?
Select each correct answer.
BC←→ and DE←→
CD←→ and BE←→
AD←→ and BC←→
AB←→ and AD←→
A square pyramid is a pyramid with a square base. In this problem, this base is formed by the points B, C, D and E as illustrated in the Figure above. So, the correct answers are:
First. (BC←→ and DE←→)
This is indicated in Figure 1. As you can see, the red lines are parallel, that is:
[tex]\overline{BC} \ is \ parallel \ to \ \overline{DE}[/tex]
Recall that two lines are parallel if they are always the same distant apart in which case they are equidistant, that is, they never meet.
Second. (CD←→ and BE←→)
This is indicated in Figure 2. As you can see, the green lines are parallel, that is:
[tex]\overline{CD} \ is \ parallel \ to \ \overline{BE}[/tex]
Answer: The correct options are
(A) BC←→ and DE←→
(B) CD←→ and BE←→
Step-by-step explanation: We are given to select each pair of sides that are parallel to each other in the square pyramid.
We know that
the base of a square pyramid is a square. And the opposite sides of a square are parallel to each other.
So, in the given square pyramid ABCDE, the base is a square BCDE.
Therefore, the pair of parallel sides are
BC and DE ; CD and BE.
This implies that option (A) and (B) are correct.
Thus, the correct options are (A) and (B).
