Sierra plays a video game an earns 2,578 points. If she plays the game 5 more times and earns the same number each time how many points will she get? i really need help im a 4th grader
Answer:
Total points= 12,890 points
Step-by-step explanation:
Giving the following information:
For each time Sierra plays, she earns 2,578 points. Therefore, the total point formula is:
Total points= 2,578*x
x= number of games played
Now, we multiply for 5 plays:
Total points= 2,578*5
Total points= 12,890 points
A students that 42% of 78 is 45
Answer:
this is incorrect. 42% of 78 is actually 32.76

45
26
90°
45
A. 132
B. V13
C. 1
D. 18
E. 13
OF /26
Answer:
Option (A)
Step-by-step explanation:
From the triangle ABC given in the picture,
Since, ∠BAC and ∠BCA are equal in measure, opposite sides of these angles will be equal.
AB = BC
Therefore, ΔABC is an isosceles triangle.
By applying Pythagoras theorem in ΔABC,
AB² + BC² = AC²
AB² + AB² = AC² [Since, AB = BC]
2(AB)² = AC²
2(AB)² = (26)²
AB² = [tex]\frac{676}{2}=338[/tex]
AB = [tex]\sqrt{338}[/tex]
AB = [tex]\sqrt{169\times 2}[/tex]
= [tex]13\sqrt{2}[/tex] units
Therefore, Option (A) will be the answer.
Answer:
A: 13 times the square root of 2.

Yoshio has three peices of fabirc. Each piece of fabric has the same length. The total length of the fabric is 2 1/4 yards. What is the legth of each pice of fabric?
Answer:3/4
Step-by-step explanation:2 1/4/3=3/4
Length of each piece of fabric is [tex]\boldsymbol{\frac{3}{4}}[/tex] yards.
Define length.The term "length" involves the measurement of distance. Length is a variable with the value distance in the International System of Quantities.
Number of pieces of fabric [tex]=3[/tex]
Total length of a fabric [tex]=2\frac{1}{4}[/tex] yards
[tex]=\boldsymbol{\frac{9}{4}}[/tex] yards
Therefore,
Length of each piece of fabric [tex]=\frac{9}{4}\div 3[/tex]

If it took eight men ten hours to build a wall, how long will it take four men?
Answer:
I want to say 20
Step-by-step explanation:
4 is half of 8, so double the time and its 20.........
Since it took 10 hours for 8 men to build a wall. If you had 4 men build a wall it would most likely take twice as long than if there were 8 men due to less people.
So it would take 20 hours for 4 men to build a wall.

2 over 9 minus 1 over 3 in simplest form
Answer:
2/9 - 1/3 (If you want to solved: -1/9)
Step-by-step explanation:
2 over 9 is 2/9 minus is just - and 1 over 3 is 1/3 so the equation looks like this: 2/9-1/3
To solve this you need to multiply the 1/3 by 3 on both the denominator and numerator: 2/9-3/9
simplify: -1/9

in the circle below, the sum of which arcs is equivalent to arc CG?
arc CG = arc CD + arc FG
arc CG = arc CF + arc EG
arc CG = arc CE + arc DG
arc CG = arc CE + arc EG
Answer: arc CG=arc CE+ arc EG
Step-by-step explanation:
The arc CG is the sum of arc CE and arc EG option fourth arc CG = arc CE + arc EG is correct.
What is a circle?
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle shown in the picture.
As we can see the arc CG is marked on a circle.
CG is the sum of CE and EG.
or
arc CG = arc CE + arc EG
Thus, the arc CG is the sum of arc CE and arc EG option fourth arc CG = arc CE + arc EG is correct.

how to find the area of a generic quadrilateral
Answer:
Area = base × height, or A = b × h for short. Example: If the base of a rectangle has a length of 10 inches and the height has a length of 5 inches, then the area of the rectangle is simply 10 × 5 (b × h) = 50 square inches.

A. All real numbers
B. All odd integers
C. All integers
D. All negative numbers
E. All even numbers
The requried range of the given greatest integer function is all integers. Option C is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Given expression g(x)= [[x/2]],
Since the given expression is the greatest integer function so the range of the function will be all integers as given as,
For example,
x = 3
g(x) = [[x / 2]]
g(3) = [[3 / 2]]
= [1.5]
= 2 [since for greatest integer function [x] = x + 1 or = x]
Thus, the requried range of the given greatest integer function is all integers. Option C is correct.

A number has a 6 in the tenths place. The number also has a digit whose value is 1/10 the value of the 6 in the tenths place. Which could be the expanded form of the number?
Answer:
The expanded form of the number is
= 6 × 1/10 + 6 × 1/100
= 6/10 + 6/100
= 0.6 + 0.06
The number is = 0.66
Step-by-step explanation:
A number has a 6 in the tenths place. The number also has a digit whose value is 1/10 the value of the 6 in the tenths place. Which could be the expanded form of the number?
We are told that a number has 6 in its tenth place
This means
6/10 = 0.6
The number also has a digit whose value is 1/10 the value of the 6 in the tenths place.
This means
= 6/10 × 1/10 = 6/100
0.6 × 1/10
= 0.06
Hence, the expanded form
= 6 × 1/10 + 6 × 1/100
= 6/10 + 6/100
= 0.6 + 0.06
= 0.66
