Answer:
25
Step-by-step explanation:
If it's 5 for every 4 and the bag has 20, 4*5 = 20 and you'd have to do that to the 5 as well to get 5*5=25.
Which of these statements is true? Sin 18° = cos 72°, sin 55° = cos 55°, sing 72° = cos 18°c both a and c
Answer:
Sin 18° = cos 72° and sin 72° = cos 18°
Step-by-step explanation:
According to trigonometry identity;
sin Ф = cos(90 - Ф)
for Sin 18° = cos 72
Ф = 18°
Substitute into the expression
sin Ф = cos(90 - Ф)
sin 18 = cos(90 - 18)
Sin 18 = cos 72
Hence the statement id true
For sin 72° = cos 18
Ф = 72°
Substitute into the expression
sin Ф = cos(90 - Ф)
sin 72 = cos(90 - 72)
Sin 72 = cos 18
Hence this statement too is correct
The two correct statements are Sin 18° = cos 72° and sin 72° = cos 18°

During a walk a thon,noahs time in hours was,t,and distance in miles,d,are related by the equation 1/3d=t .A gragh of the equarion includes points (12,4)
Question:
During a walk-a-thon, Noah's time in hours was t, and distance in miles, d, are related by the equation [tex]\frac{1}{3}d = t[/tex]. A graph of the equation includes points (12,4).
1. Identify the independent variable.
2. What does the point (12,4) represent in this situation?
3. What point would represent the time it took to walk [tex]7\frac{1}{2}[/tex] miles?
Answer:
(a) d
(b) He spent 4 hours to walk 12 miles
(c) [tex](7\frac{1}{2},2\frac{1}{2})[/tex]
Step-by-step explanation:
Given
[tex]t = \frac{1}{3}d[/tex]
Solving (a): The independent variable
The independent variable, in this problem is the distance walked. Because the distance walked stands alone, and it is when the distance is known, that the time spent is known.
Hence:
The independent variable is distance (d)
Solving (b): What (12, 4) represents
This implies that:
[tex]distance = 12[/tex]
[tex]time\ spent = 4[/tex]
So: He spent 4 hours to walk 12 miles
Solving (c): Point to represent the time to walk [tex]7\frac{1}{2}[/tex] miles
This implies that:
[tex]d = 7\frac{1}{2}[/tex]
Substitute [tex]d = 7\frac{1}{2}[/tex] in [tex]t = \frac{1}{3}d[/tex]
[tex]t = \frac{1}{3} * 7\frac{1}{2}[/tex]
Express as improper fraction
[tex]t = \frac{1}{3} * \frac{15}{2}[/tex]
[tex]t = \frac{5}{2}[/tex]
Express as mixed number
[tex]t = 2\frac{1}{2}[/tex]
So: The point is, [tex](7\frac{1}{2},2\frac{1}{2})[/tex]

how do you multiply add and divide fractions?
Answer:
If the denominators are not the same: First, make them the same. Then add or subtract like fractions with the same denominators.
Step-by-step explanation:
the first step when multiplying fractions is to multiply the two numerators. the second step is to multiply the two denominators. simplify the new fractions. the fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.
to add or subtract fractions they must have the same denominator. if the denominators are already the same then it is just a matter of either adding or subtracting the numerators if the denominators are difrent then a common denominator needs to be found.

5. m∠2 = 180-59-55 = 66
m∠1 = 180-66 = 114
6. 2x+3x+4x=180
x(2+3+4)=180
x(9)=180
x=180/9=20
Plug back in to check:
2(20)+3(20)+4(20)=40+60+80=180
7. (3,8) to (9,24)
(9,24)/(3,8) = (3,3) so scale factor = 3
8. (12,15) to (4,5)
(4,5)/(12,15) = (1/3,1/3) so scale factor = 1/3

Answer: Number 9: x = 20, Number 10: x = 65
Step-by-step explanation:
Number 9:
3x + 10 = 90 - x
3x + x = 90 - 10
4x = 80
80 / 4
x = 20
Number 10:
2x + 15 = 145
2x + 15 - 15 = 145 - 15
2x = 130
2x / 2 = 130 / 2
x = 65

[tex] \frac{5x - 2}{2} = 9[/tex]
Answer:
x = 4
Step-by-step explanation:
[tex]\frac{5x -2 }{2} = 9 \\[/tex]
Cross multiply,
5x - 2 = 9*2
5x - 2 = 18 {Add 2 to both sides}
5x = 18 +2
5x = 20 {Divide both sides by 5}
x = 20/5
x = 4

Based on the equation 7x+42=y predict the number of customers to visit the frozen yogurt when it's 10 degrees
Answer:
112 visitors
Step-by-step explanation:
Given the prediction equation :
y = 7x + 42
x = temperature
y = number of visitors (customers)
Number of visitors when temperature is 10 degree
y = 7(10) + 42
y = 70 + 42
y = 112
Hence, the model predicts that 112 customers will visit when temperature is 10 degrees

A home security company provides security systems for $6 per week, plus an installation fee. The total fee for 10 weeks of service is $345. Write and solve a linear equation to find the cost of the installation fee.
Answer: $285
Step-by-step explanation:
Let the installation fee be represented by x.
Therefore, the equation to solve the question will be:
= x + 6w
where,
x = installation cost
w = number of weeks
x + 6w = 345
x + 6(10) = 345
x + 60 = 345
x = 345 - 60.
x = 285
Therefore, the installation fee is $285
